39 .1. General .-a. Scope .-This section coversa general descrip-

tion of the on-carriagefire control andsighting equipment for the 16-

inch barbette carriage-M4, with instructions for operation of the

equipment, and necessarycare and maintenance to be performed by

battery personnel.h. (1) The fire control equipment forms a coordinated system for

placinga target under effective firs in the minimum.amount of time.(2) The completefire-control equipmentincludes instruments for

determining target data, plotting room equipment for translatingthetargetdata into gun pointing data, anda data transmission systemfortransmitting thegunpointing data from theplotting room to theguns. Thegunpointing data consists offiring azimuth (in degreesand hundredths) andelevation (in mils).

(3) The data transmission system M5is used withthe 16-inch bar-bette carriage M4. Arrangement ofthe system is shown in figure173 .7 ..Thesystem includes an azimuth indicatorM6 andan elevationindicator M5f r each carriage. Theindicators are mountedon thecarriage ne the- a-versingand elevating handwheels, respectively.Theindicators have "inatch-the-pointer" dials. Thehandwheel oper-atorskeep the dial pointersmatched and thereby applythe trans-mitted data to the gun. Aready signal lamp in each indicator showswhen thetransmitted data are correct for firing.

(4) Theindicators receivetheir data either from thegundata com-puter M1,or from the azimuth transmitterM5 and elevation trans-mitter M6. The gun datacomputer and the transmitters are in theplotting room. The transmitters are used in connection with theconventional plotting board method of determininggun pointingdata. Thegun data computer automatically computes gunpointingdata directly from the target data, and in effect replacesthe trans-nzitters and plottingboard equipment .

with acloth slightly moistened with solvent, dry-cleaning, and wipe

thesurface witha clean cloth.

d. (1) To obtain satisfactory vision, exposedsurface of lenses and

other optical parts must bekeptclean and dry. Corrosion and etching

of the surface of theglasscan be prevented or greatlyretarded by

keepingthe glassclean and dry.

(2) For wiping optical parts use only paper, lens, tissue. The use

ofcleaning cloths for wiping opticalparts is not permitted. Do not

wipe lenses or windows with the fingers. To remove dust, brush the

glass lightly with a clean brush, camel's-hair. Rapthe brush against

a hard body to knock out the small particles of dust that cling to the

hairs. Repeat this process until all dust isremovedfrom the glass

surface. An additional brushwith coarse bristles is provided with

some instruments for cleaning mechanical parts. Each brushshould

be used only forthe purpose for which it is intended.

(3) Exercise particularcareto keep optical parts free from greaseand oil. Toremovegrease oroil from optical surfaces, apply soap,liquid, lens cleaning, with a tuft of lens paper. Wipe thesurfacegentlywith clean lens paper. 1f lens clearing liquid soap is notavailable, breathe heavily on the surface and wipeit off with cleanlens paper. Repeat this process until the surfaceis clean.

(4) Moisture maycondenseon theoptical partsof theinstrumentswhen the temperatureof the parts is lower than that ofthe surround-ing air. The moisture,if not excessive, canbe removed by placingthe instrument in a warns place. Heat fromstrongly concentratedsourcesshould notbe applied directly as it may causeunequal expan-sion ofparts, thereby resulting in breakage ofoptical partsor inac-curacies in observation.

39 .3. System, data transmission,X5 (on-carriage compo-nents) .--ca. Description.-The on-carriage componentsof the data,transmission systemMy consist of the azimuth indicator Ms, the ele-vation indicator M5, the switch box and the junction boa (fig. 173.2).

(1) The azimuth andelevation indicators receive four elements ofdata: coarse azimuth and fine 'azimuth; coarse elevationand fine ele-vation. The indicator dial for each of these four elements consistsof an inner dial bearing a pointer index, an outer concentric ringbearinga similarpointer index, and a graduated scale. The innerdial is electrically driven by thecorresponding transmitter elementin theplotting room, and its pointer index.shows the same scale readingas the plotting room transmitter. The outer concentric ring isgearedto the traversing or elevating drive of thegun carriage, and itspointerindex shows theactual azimuth or elevation of the gun. Hence. when

both the coarse and the fine inner andouter pointer indexes are:hatched, the gun is at the same azimuth or elevation as that whichis set on the transmitter dials in the plotting room.

(2) For each element of data transmitted, an a-c synchronoustransmitter, an a-c synchronous repeater,and connecting means areprovided. The repeaters and transmitters resemble small electricmotors in external appearance. Therepeater follows the motion ofthe distanttransmitter and synchronizes (lines up) with the trans-mitter when power is applied, regardless of relative position priorto application of power. The repeatercannotcarry mechanical load,and is thereforeused in connection with a "follow-the-pointer" drive.Each repeater carries onlyan index (electrical) with which anotherindex (mechanical), connectedto the element to be positioned, isbrought into alinementby means of a handwheel or other drive.

(3) The azimuth indicator M6 (fig. 173 .3)is mounted on theleftside of the gun carriage. Thecoarse dial indicates 360° perrevolu-tion, and the fine dial indicates 10° per revolution. Aready signallamp is mountedbehind aredbull's-eye between the dials. The en-tire mechanism is inclosedin aweatherproof caseprovided withashatterproof glass window.

(4) The elevation indicator M5 (fir. 173 .4)issimilar in construc-tion to the azimuth indicator except that the unit ofgraduation ofthedials is themil instead of the degree. The coarsedial is graduatedfrom 0to 1,600mils in 104-mil divisions and numbered every 140 mils.The fine dial is graduated from 0 to 100 mils in 1-mildivisions andnumbered every 10 mils.

(5) A switch boa (fig. 173.2) near theelevationindicator containsa trouble lamp receptacle and a toggle switch. Theswitch operatestheelectric lamps in the indicators forilluminating the indicator dials .

(6) On-carriage wiring is carried in metal conduits to the gunjunction bog, whichismounted in the lower rotating part ofthe guncarriage, above the emplacement well. Aloop offlexible cable leadsfrom the gun junction boa to theemplacement junction box, whichis mounted in astationary position on the side of,the emplacementwell. The flexible cable loop permits free traverse of thecarriagethroughout the field of fire. From theemplacementjunction boathewiringis carried byunderground armored cable to the mainjunctionbox in the plotting room.

b. Operation .-(1)Ifpossible, verify theadjustments before com-mencing operations. These adjustments are described in dbelow.

(2) At theguns, the traversing and elevatinghandwheel operatorsfirstmatch the pointer indexes on the coarse indicator dials and then

Thus,acoarseindication between 40' and5D°,togetherwithafine indication of5 .15° is read as 45 .7.5°.

d.Veriflcation ofadjustments.-The following adjustments shouldbe checkedwhen -possiblebeforecommencing operation

Page 11: 16-Inch Seacoast Gun

TX 9-471CZ TECHNICAL MAN-UAL

(1) Orientation .-The outer dials on the azimuth and elevation iiz-dicators should indicate correctly the actual gun azimuth and eleva-

tion. Instructions foradjustment are given in ebelow.

(2) Synchronization .-The innerdials on the azimuth and eleva-

tion indicators should read the same asthe corresponding transmitter

dialswhen the system is energized. Theyshould alsoread thesame

as the corresponding dials on the gun data computer. Instructionsfor adjustment are given in f below-.

(3) Ready signal lamps andindicator illuminating lamas .-Tyrolamps are connectedinparallel at each lamp position,so that if onelamp burns out the other lamp will remain operative. Ifthe lampsat any position show reduced illumination, indicating that one of thelamps is burned out, the defective lamp should be replaced. Instruc-tions forlamp replacementaregiven in gbelow .

. e. Orientation .-(1) Orientation refersto themechanical adjust-ment ofthe azimuth and elevation indicators so that when thegun ispointed in agiven direction,the outer indexesfor azimuth and eleva-tion will indicate correctly the direction in which the gun is pointed.

(2) Each gun is oriented independently of the other. The instruc-tionswhich follow are for one gun. Readjustment will seldom berequired after the initial adjustment. Readjustment will, however,be required afterany disassembly operations involving the indicatordrives on the gun mount.

(3) Orientation of azimuth, indicator M6.-(a) Using the boresights traversethe gununtil it is accurately directedon a datum point.

(b) Note that thezero adjusting device is located on the split. gearatthe bottom of the azimuth indicator drive shaft- tube. The zeroadjusting device has an adjusting worm anda clamping screw. Thehead of the adjusting worm is slotted for screw driver operation.

(c) Loosen theclamping screw andthen turn the adjustingwormasrequired until theindicator scale reading (the combined readingof the coarse and finescales) is thesame as the knownazimuthof thedatum point. Tighten the clamping screw to retain theadjustment.

(4) Orientation of elevationindicator 11.5 .---(a)Usingthe clinom-eter, set the gun to aconvenient reference elevation. Any elevationcanbe chosen, butthegun must be setaccurately to thechosen eleva-tion .

(b) Note that the zero adjustingdevice is located on the shaft be-hind the elevation indicator. Thezero adjusting devicehas an ad-justing worm and a clamping screw. The adjusting worm and theclamping screw have knurled socket heads whichcan be operatedeither by hand orby use ofa 7/a,-incli socket head set screw wrench.

(c) Loosen the clamping and then turn theadjusting worm as re-quired until the indicator scale reading (the combined readingofthe coarse and fine scales) is the same as the gun elevation. Tightentheclamping screw to retain the adjustment.

f.Synchronization.-(1)Synchronization is theadjustment of the

indicator inner indexes to the same reading as thecorresponding

transmitter dials.

Fioauw 173.3 .-Elevatlon indicator 115-ready signal larupsandsynchronizing adjustingshafts.

(2) Synchronization is performed with the system energized. Itwill seldom be necessaryto alterthesynchronization adjustments, butthe adjustments should be verified periodically.

(3) Slotted adjustingshafts forthe coarse aiid fine indicatorinnerindexes are locatedunder the indicator signal lamp cover (fig. 1"x3.5).Themotion of these shafts is limited to afew turns, sufficient topro-vide adjustment under all normal conditions. No attemptshould bemade to force a shaft if astop is encountered.

(4) To synchronize theazimuth or elevationindicator, energizethe system andnote the readings ofthe coarse and fine transmitteroutput dials. By'means of theslotted adjusting shafts,set theinnercoarse and fineindexes to read thesame as thecorresponding trans-mitter output dials.

Page 13: 16-Inch Seacoast Gun

TX 9-471CI TECHNICAL MANUAL

(5) Do not attempt to synchronize if the direction of rotation of.anyof the indicatorinner indexes is reversed, or if there is alargedeparture from synchronism (often amultiple of 64°). Such condi-tion indicates a wiring fault which must first be determined andcorrected.

(6) Synchronizing adjustmentsperformed with the azimuth andelevation transmitters -will normallyhold also for the gun data com-puter. If thesynchronizing adjustment changeswhen thegundatacomputer is connected in placeof the azimuth and elevation trans-mitters, it will be necessary to adjust the transmitter elements in the

transmitter to bring them into agreement with the correspondingtransmitter elements inthe gun datacomputer.

g. Lamp replacement.-Lampsused in the azimuth andelevationindicators are Mazda No. 51 type (1 cp, 6-8volts,412ampere,G 31/2

bulb). Thelamps areaccessible for lamp replacementafter removal

of the lamp well covers. (See figs.173.5and 173.6 .)h.. Care and preservation.- (1) Power shouldbeswitched offbe-

fore cables are connected or disconnected.Seethat cables aresecurelyheld in the receptacles beforeturning on the power.

(2) Do notkink or twist the cables. Avoidbendingthe cables ona short radius, or allowing them to chafeagainst moving parts. Keep

Page 14: 16-Inch Seacoast Gun

TM 9-47116-INCH SEACOAST GUI MATERIEL C].

the cablesclean of oil or grease. To remove oil or grease, wipe the

area as clean as possible andthen wash with soapy water.

(3) When the cables arenot connected, keep plugs andreceptacles

closed with thecovers provided to exclude dirt and moisture.(4) When the cablesare connected, keep the plugs andreceptacles

tightened firmly together by means of the round nuts. Screw the

plug and receptacle coverstogether tokeep them from dangling and

to protect the threads.(5) When disconnectinga cable, pull onthe body of the- plug. Do

not pull on the cable or spring.(6) The indicators and transmitters do not require lubrication

when in service. Suchlubricationasisrequired is performedin con-

nection with major disassembly or overhaul.(7) Should anyrepeater startto "run away" (run asa motor ata

high rate ofspeed),cut offthe power immediately and then reapplypower after the repeatercomes torest. Repeatersaremost likely torun affray at the instant when power is applied.

(8) Should arepeater on either gunbind or stickduring operation,turn off thepower to that gun by means of the switch in the mainjunction box. .A,binding orsticking repeater will cause inaccuratetransmission of data, and will be subjectto overheating and possibleburn-out . Referto ordnance maintenance personnel for repair orreplacement.

39 .4. Mount, telescope, M35, with telescope X31 .-a. Gen-eraZ.--The telescope mounts 11235 (fig.173 .7)aremounted on therightand left side of the carriage. Thetelescope M31 fits into thetelescopemount. The combination of telescope mounts and telescopes formsthe sighting element for aiming thegun in azimuth (case II pointing).

b. Description. a f tekSCOPe mount 111J5.-(1) The cradle of thetelescopemount has clamps and locatingsurfaces for securing thetelescope. The open sights at thetop of the cradle provide a line of

sight parallel to thetelescope line of sight, and are used forrapidapproximate aiming. The front. sight can be folded down when notin use.

(2) The elevatingknob of the telescope mountelevates or depressesthe cradle and telescope.

( 3) The deflectionknob,deflectsthe cradle and telescope in azimuth.Deflection motionis read in degrees andhundredths of degrees on thescale and micrometer. The deflection scale is calibrated from 0° to20° in 1° intervals. The deflection micrometer is calibrated directlyin hundredths ofdegrees. "Normal" deflection setting (line ofsightparallel to axis ofgun bore) is 10.00°.

(4) Built-in electric. lamps illuminatethe deflection scale and mi-

crometer of thetelescopemount, and the reticlecross wires of the tele-

scope. Thelampcircuits are controlled byswitches on the rear face

of the telescope mount. Ashort interconnectingcable, whichis fur-

nished as anaccessory, ties the telescopeto the telescope mount.e. Description. of telescope M31 .-(1) The telescope (fig. 173.7)

hasan 8-power magnification anda field of view of $°45'. -

(2) The eyepiece canbe focusedto meet eyesight variations of in-dividual observers. The diopter scaleon theeyepieceenables the ob-serverto prefocus the telescope, ifhe knows his own eye correction.

(3) Amber,neutral, or clear filters canbe introduced by use of thefilter selector knob.

(4) The objective capcovers and protectsthe objectivewhen the

telescope is not inuse.d. Preparing for operation-.-(1) Clamp thetelescopein the cradle

of the telescope mount. If illumination will be required, connectthecable between the telescope and telescope mount.

(2) Focusthetelescopeby turning the focusing nut until objects attarget range appear sharp and clear. The observershouldrecordthe diopter scale setting for his future use. Ifthediopter scale settingis known, the telescopecan befocused by simply bringing the scaleto the known setting.

(3) Select the proper telescope filter accordingto thelight condi-tions. Usetheclearfilter fordim light or fornormal lightwith noglare. Use theamberor neutral filter to reduce glare. The neutralfilter is most useful when observing into the direction of the sun.

e. Operation, gun pointing.-(1) Set the deflection scale and mi-crometer to the announceddeflection by turning the deflection knob.If nodeflection is required, setto 10.40°.

(2) Traverse thegun to bringthetelescope to bear on the target.The opensights may be used initially to speed pointing. Usethe ele-vating knob to bringthetarget onto thehorizontal crosswire of thetelescope reticle, then refine the gun traverse to place the targetexactly at the intersection of the horizontal and vertical cross wires.This final operationpoints the gun in azimuth.

f. Test and adjustment.-At regular intervals depending on serviceconditions, the gun should be bore sighted to verify thealinement ofthe telescope and telescope mount. Procedure for bore sighting isas follows

(1) Placethebreech bore sight in thegun and stretch theblacklinen cord tightly across the muzzle,vertically andhorizontally in thescoremarks on themuzzle .

15

(2) Use thebore sights to point thegun at a distantdatum point,at or beyond midrange of the gun. Set thedeflection scaleand mi-

crometer of the telescope mount to read 10.40°and observe the datumpoint through the telescope. Usetheelevatingknob,if necessary, tobring the datum point onto the horizontal cross wire of thetelescope.Ifthe adjustment is correct, the datum pointwill appear exactly onthe vertical cross wire.

(3) 1f the adjustment is notcorrect, turn the deflectionknob to

bring thedatum point onto thevertical cross wire. Adjust the deflec-tion scale and micrometer to read 10.00'with the telescopein this position. To adjust themicrometer, loosen thethree screws in thecuppedend ofthe deflection knobto unclamp the micrometer,thenturn themicrometerto zero reading and reclamp. To adjust the scale. loosenthe screw at each end ofthe scaleand shift. the scale to bringthe"10"graduation inregister with the index, then reclamp.

g. Lamp replaaemertt .-The electric lamps are mounted in indi-vidual lamp receptacles which are removable topermitlamp replace-ment. The lamps arethe sametype asthose used in the azimuth andelevation indicators. Toremovethelamp receptacle, loosen the smallheadlessclamping screw (using the jeweler'sscrew driver provided)in the edgeof the receptacleand then unscrew thereceptacle.

h,. Care and Preservation.- (1) Refer to paragraph 39.2 for generalcare and preservation instructions.

(2) Keepthe objective capin place whenever the telescope is notin use. During idle periods,storethetelescope in thecarryingcaseprovided.

(3) Lubricate the telescope mountoccasionallyby applying a dropof oil, lubricating, for aircraft instruments and In'achine guns, in eachof the six oilcups . Lubricate sparingly. Wipe offany excess lubri-cantto prevent accumulation of dust and grit.

1. SCOPE.

a. Thismanual contains all the essential information ofatechnicalcharacter required by the using arms and services forthe identification,use and care of the weapon, ammunition, and spare-parts andacces-sories; but does not include the sighting and fire-control equipment.

b. This technical manual is intended to cover -only 16-inch Barbette

Carriage, M4 materiel. Seesection XV for publications covering 16-inch

Barbette Carriage M1919, M1919M1, M2 and M3.

c. Disassembly, assembly and repairs by battery personnel will be

undertaken only under the supervision ofan officer or ordnance mechanic.

al. In caseswherethe nature of the repair, modification or adjust-ment isbeyond the scope and/or facilities of the batterypersonnel, thelocal or otherwise designated ordnance servicewill be informed in orderthat trained personnel with suitable tools and equipment may beprovided.

CHARACTERISTICS .a. The 16-inch Barbette Carriage gunmaterielM4described herein

consists of thefollowing units :16-inch Gun Mark 11 Navy design.16-inch Gun Cradle and Recoil MechanismNavy design.16-inch Barbette Carriage (exclusive of cradle and recoil mechanism)

Army design.h. The materiel isofthe Seacoast type,set in a permanentemplace-

ment and protected by ametal shield against aerial, land or navalbombardment .

". The casemate designof emplacement limits the elevation ofthegun as well asthe degree of traverse of the rotatingparts.

3. DIFFERENCE IN MODELS.a. The 16-inchBarbetteCarriageM4is a modification of Barbette

Carriage model 1919. The previous modifications to the M1919BarbetteCarriage are designated M1919M1, M2 and M3. The variations indesign and construction are substantially as follows:

NOTE: The forces required to initiate movement in.elevation or de-

pression of the gun when appliedto the elevating crankor elevating

handwheel vary with the angle of elevation of the gun. These forces are

also affected by the weight of the projectile and powder in the breechwhenthe gun is loaded.

d. The gunis in balance at level position (zero elevation)when it

is loaded with a weight equaltoone-half the weight of the normal

powder charge plus one-half the weight of the projectile. Thisweight is

inserted in the breech in such position as to simulate the projectile and

its propelling charge. When unloaded the gun is muzzle-heavy at all

points of elevation.It will depress by gravity withno measurable forceapplied to the elevating crank orhandwheel when the elevating brakeband is released.

e. The effortrequired to elevate and depress the gunas outlined inthe above tabulation was determined by shop tests made lit the timeof assembling the parts. These effortswill vary as a result of changesin temperature and for other reasons.

DESCRIPTION AND FUNCTIONING

5. DESCRIPTIONAND FUNCTIONING OF GUN.

a. The gun (fig. 6) consists of tube, liner, jacket, hoops,rings (fig.

7), recoil band (fig. 8) and the breech mechanismwith closing cylinder

and gas ejector systems.

(1) GUN KEY. The gun is provided witha stake-in key (fig . 6)'

attached to its uppersurface which slides through a keywayin the cradle

and prevents rotationofthe gun duringrecoil and counterrecoil.

(2) AUTOMATIC ELEVATING STOPS. To prevent elevation or depres-

sionofthe gunbeyond prescribed limits automaticdevices are provided.

These consist ofprojections nearthe upper and lower ends ofthe elevat-

ing racks which engage with a bufferlever (W, fig. 87) onthe right side .

frame and abuffer lever (H, fig. 88) on the left side frame. When the

limits of elevationordepression are reached the stops onthe elevating

racks come intocontact with elevating buffers preventing further eleva-

tion or depression of the gun.

(3) HREECHELOCK. The breechblock (T, fig. 9) and (fig. 10) is of theinterrupted-step-thread design and is so constructed as to enter thebreechrecess easily and quickly whereit is ldcked in place by a rotarymotion of the block. Thisrotary motion is effected by meansofa systemofrotating cams and rollers attached to the gun breech and breechblock(figs. 10, 11, 12 and 13). The action of opening or closing the blockautomatically engages or disengages the threads ofthe block from thethreads of the breech recess. The blockis provided with an obturatorspindle (J, fig. 11), obturator nut (G, fig. 11),obturator spring (H, fig.11), dummy pressure plugs (L, fig. 11), pressure plug washers (K, fig.11), front ring (E, fig. 11), rear ring (S, fig. 11), inner ring (C, fig. 11)and gas check pad (D, fig. 11). The end of the obturator spindle isdesigned to receive the firing lock.

(4) ROTATING CAM (UPPER). Arotating cam (upper) (fig. 14),which housesthe salvolatch, islocated onthe upper left-hand surfaceof the gun breech against which a roller (N, fig. 13),connected tothebreechblock, operates to rotate the block. The block carrier is raised orlowered in the operation of closing or opening the breech.

DESCRIPTION AND FUNCTIONING

1, Traversing Group. The traversingmechanism enablesthe gunnersto traverse the mount through its maximum permissible movementof145degreesso as to point theguys at anygiventargetwithin its held offire. Themount can be traversed by power or by hand as the occasionrequires.

(1) TRAVERSING PINION AND RACK. The traversing bracket (V, fig.91), boltedto the racer, houses the traversing pinion (U, fig. 91) andshaft. The pinion mesheswith the traversing rack(K, fig. 30), fastenedto the stationary base ring, so thatrotation of the pinion causes themount to revolve on the traversing rollers.

(2) TRAVERSING GEAR-FRICTION Box ASSEMBLY.

(a) A traversinggear-friction device protects the traversingmecha-nisrnagainst excessive strain, due toabrupt starting orsudden stoppingof the weight traversed,and provides positive drive ofthe traversingpinion within safe limits of strain.

(b) Arnulti-diskclutch inside of the friction disk oil container inthe friction box assembly (J, fig. 91) limits theforce or strain trans-rnittedthrough the friction device tothe grip ofthis clutch. Frictionis accurately maintainedat the desired point bypressing together thedisks of the multi-disk clutch by means ofBelleville springs andbylubricating the disk surfaces.Lubrication is accomplishedby filling thefriction disk oil container with oil. The traversing shaftnut (R, fig. 92)is used to adjust thecompressionof the Belleville springs and in thismanner to control thegrip of the multi-disk clutch (fig. 141).A screw(T, fig. 92) locks thetraversing shaftnut in position.

(3) TRAVERSING CLUTCH.

(a) Thetraversing clutch (AA, fig. 92) provides alternativemechani-cal connection to thetraversing pinion either for the traversing crank-shafts- (E, fig. 91) or for the traversing-speedgear and so providesforeither handor power traversing ofthemount:

(a) Atraversing shiftlever (L,fig . 91, and N, fig.94), located on theleft side of theframe, operates the clutchshifterfrom a position which

121

(b) The traversing clutchis keyed to theclutch shaft which drivesthe friction box gear (Ua fig. 92) connected tothe traversing pinion. --

(4) TRAVERSING CLUTCH SHIFTER. A traversing clutch shifter (E,fig. 92) slides the clutch onthe clutch shaftso as to engage eithertheclutch bevel gear(Z, fig. 92) or theclutch spur gear (B, fig. 92). Bothgearsturn freely onthe clutch shaft when disengaged from the clutch.Atrain of gearsconnects the clutchbevel gearto eachtraversing crank-shaft (E, fig. 91). The clutch spurgear is drivenby the traversingspeedgear throughanother gear train. `-=--

Page 59: 16-Inch Seacoast Gun

is readilyaccessible to the azirnuth operatoratthe left side of the mount

(fig. 139).

16-INCH SEACOAST GUN MATERIELGUN MK. 11Ml ; BARRETTE CARRIAGE M4

(b) When operating by hand,a spring plunger in the shiftlever

handle (L, fig. 93) must beengagedin the upperhole marked"HAND"

in the locking bracket (Q, fig. 94). When operating by power, the lever

handle plunger must beengaged in thelowerhole, marked "POWER"

in the lockingbracket (fig.138).

(5) TRAVERSING CRANKS. Traversing cranksassembled on crank-

shafts on theright andleft sides of the carriage are used to swingthe

gun rapidly from onetargetto another.Direction plates (H, fig. 94) on

each crankshaft bracket cover (E, fig. 93) indicate the direction of

rotation of the crank to traverse the piece tothe right or left.

(6) TRAVERSING SLOW-MOTION HANDWHEELS.

(a) Accurate adjustmentofazimuthis accomplishedby using thetraversingslow-motion handwheels(fig. 141) of whichthere are twosets,one (U, fig. 95) and (fig. 97) on the right side and one (M, fig.93)

and (fig. 96) on the left side of the carriage.Either the right-side or left-side traversingslow-motion handwheelsmay be used as the occasion

requires, but they cannot be used simultaneously.A direction plate onthe outer handwheel ofeach traversing slow-motion mechanism indi-

cates the direction ofrotation ofthe handwheelsto traverse the pieceto the right or left.

(b) Aclutch (H, fig. 98) in each slow-motioncrankshaft bracket(E, fig. 98) engagesand disengagesthe adjacent traversing slow-motionmechanism.The clutches are operated by rods (A, fig. 98, and C, fig.91) which are connected with the clutch treadles (D, fig.91, and M, fig.

99) by shafts and leversunder the platform. Acounterweight (D, fig.80, and L, fig. 99) keeps each treadle raised when unlatched. Fullydepressingthe treadle engagesthe traversing slow-motionmechanism.only on the side of the carriage where the operation takes place. Thetreadle islocked in this position bypushing it outward from the centerof the carriage so as to engage the dog on thetreadle with thelatchplate (N, fig. 99). Thetreadleis released by kicking it inward towardsthe center of the carriage.The counterweight raises thetreadleand so

disengagesthe slow-motion clutch connected to it.

(7) TRAVERSING SPEED GEAR. Thetraversing pinion maybe driven

at varying speeds -in either direction orheld motionlessbythe hydraulicspeed gearwhile the motor end of thespeed gear is driven atconstant

DESCRIPTION AND - FUNCTIONING

speed and in one direction only.When traversingby power, the motor

supplies the power for thetraversing pinion but thespeed ofthe pinion

is controlledby the traversinghydraulic speed gear operating through

the horizontal control shaft (R, fig. 91, and U, fig. 100).

(S) TRAVERSING CONTROL STATIONS.

TM 9-4715

(a) Agroup of bevelgears (fig. 100)connects thehorizontal control

shaft (U, fig. 100) to the two control handwheels(F and K, figs. 7.02).

The lower end of the vertical shaft is provided with bevel gears (C, fig.1,01)connecting with the lower indicator shaft (D, fig. 101). This

arrangement permits-the power traversingof the gun to be controlled

from either of two stations-the azimuth observer's cab (M, fig. 102)

or the left side azimuth operator's station.From the azimuth observer's

cab the gun may be traversed by power (fig.143) to any desiredreading

of the azimuth indicator (G, fig. 103).The azimuth operator on theleftsideof the mount can read.the azimuth data indicator (K, fig. 94) fromhis position whiletraversing the gun. Heis able tooperate according to

_the reading on the data receiver ofthe azimuth dataindicator or hecanlay the piece to an azimuth reading as occasion requires.

(b) Markings on the traversing control. gear cases(B, fig. 103,andR, fag. 93) of eachtraversing control mechanism indicatethedirectionin which the control handwheel (D, fig. 103,and T, fig. 94) is to bemovedfromneutral position in order to traversethe mounttothe rightor left. When the zero mark on the indicator dial (C, fig. 103,and Q,fig. 93) coincides with the index line on thegear case, thetraversingcontrol is in neutralposition and thespeed gear holds the traversingpinion motionless.The traversing controlmechanism (fig.103) isshownin neutral position. The graduations marked "one-fourth, one-half,three-fourths and full speed" at each sideof the zero mark indicate thetraversingspeed at whichthecontrol is set when they coincidewith theindexline on the gear case.

(9) TRAVERSING LIMIT SWITCH. The power traversing of the pieceis stopped bya traversing limit switch(S, fig.90.)and (fig. 104) breakingthe electriccurrentto the traversing motorwhen the mount approachesits limit of traverse in either direction.It is mounted on aplate (K, fig.104) at thebottom of the traversing bracket (C, fig. 104). Near thelimit of traverse 'in either direction, alimit switch stop rail, of whichthereare two (B, fig. 104),engages the cam wheel (R, fig.104) of thelimit switch, forcingtheoperatinglever arm (Q, fig. 104) to swingback,thereby.operating the switch. A slight movement ofthe limit switch

123

operating lever arm in eitherdirection from its normal central position

will operate the switch soasto deenergize the traversing motor.

(a) The limitswitchstop rails are so located onthe base ringas

to break the electric circuit when the carriage has traversed 66 degrees

in either direction fromthe centerlines of the emplacement.

(b) Afterthe lirnit switch has stopped the traversing ofthe piece,

and so long" as the limit switch cam wheel is in contact with the stop

rail, the traversing motor can be started and keptrunning only by

keeping the limit switch button at the traversing push-button station

(E, fig. 154) depressed. Before restarting the motor, the traversing

control must be set at neutral. If the mount is to be rotated beyond

the point wherethe limit switch has stopped the movement in azimuth,

caution must be exercised and the traversing control must be so oper-

ated as to. obtain a very limited traversing speed. Generally, it will beadvisable to continue traverse in the same direction by using slow-

motion hand power. (See Limits of Traverse, par. 9j (2)).

(l0) AzIMUTH DATA INDICATOR. The operator in the azimuth

observer's cab can only lay the piece to an azimuthreading onthe

azimuth circle. The azimuth . data indicator (K, fig. 94), located near

the left traversing handwheels, is for tracking in azimuth with off-

carriage fare-control instruments which transmitazimuths mechanically

too oneof the dialsof the indicator_ The azimuth dataindicator contains

two sets of pointers, one operated electrically and one by mechanical

means. The electrical pointer is controlled and operated from the off-carriage station in conjunction with the fire-control system. The

mechanical pointer is operated through a drive mechanism (R, fig. 90)

and is driven from the traversing rack by the azimuth indicator gears

(C and D. fig, 105). As the mount is traversed the rotation is trans-

mitted tothemechanical pointero ¬the azimuth dataindicator showingthe exact position ofthe gun in azimuth.

(11) ZERO AD]USTING DEVICE. Azero adjusting device (F and G,fig. 105) permits adjustment of the drive mechanism of the azimuthdata indicator soasto bringthe readings of the azimuth data indicatorand the azimuth indicator in the observer's cab into alinement. Thezero adjusting devicealso eliminates backlashat the traversingrack sothat the readings of theazimuth data indicator are not affected by thedirection of traverse of the mount.

DESCRIPTION AND FUNCTIONING

7. DESCRIPTION ANDFUNCTIONING OF RAMMER.

a. The mountis provided with a loading yammer.Itis attached tothe racer between the side framesat the rear of the gun breech.Eitherelectric orhand power may be employed ia its operation.

(1) MOTOR OPERATION. When operated by electricpower the move-ment of 'the yammeris controlled by a hydraulic speedgear directlyconnected to and driven by an electric motor.

(2) HAND OPERATION. When operated by hand, the power is sup-plied by meansof two cranks (P,' fig. 109) located on therightand leftsides of the rammer near the rear end.

(3) PARKING TABLE. A parking table (G, fig. 10$)oneither sideofthe yammer is provided to receivethe projectiles and powder charges.

(4) RAMMER CASE. The yammer case(13,fig. 108) is provided withgrooveson its inner sides whichserve as a path fortherollers on therammer chain.

(5) RAMMER CHAIN. The rammerchain (fig. 106) consistsof a seriesof links connectedby chain pins with rollers on each endwhichrunfreely in the grooves in theyammer case.

(6) U'NSTROKING DEVICE. An unstrokingdevice (P, fig. 110) pre-vents the yammer head from advancing beyondapredetermined dis-tance in the gun. When this point is reached the device returns thecontrol leverto neutral position (fig.109), therebystopping theforwardmotion of the rammer head. Azero adjusting coupling (L, fig. 110)provides adjustment oftheunstroking position of the yammer head.

(7) RAMMER HEAD. A rammer head (D,fig. 107)and (fig. 111) pro-vided with ahydraulic buffer is attached to the rammer chain. Thisbuffer preventsexcessive shockto the chain and yammer head whenoperated.The construction of the buffer provides for compression oftwo inches. It is returned to its normal position by means of buffersprings. Danger of injury to the yammer head and chain whenit iswithdrawn is minimized by meansof this buffer action and bya systemwhereby the oil used in the operation of the motor speed gear isbypassed aroundthegear, rendering itinoperative.

($) CONTROL LEVER. .

(a) The movement of the yammeris controlled by means of acon-trollever (Q, fig. 109).Moving the lever upwardto the position marked"RAM" (i3, fig. 149) drives theprojectile or powdercharge forward,and acorresponding downward movement to the position marked"WITHDRAW" (N, fig. 109) returnsthe yammerhead and pertaining .parts to the starting position .-_-

(b) Thecontrol lever is held in neutralposition by a controlleverdetent assembly (M, fig.109).Raising or lowering thecontrol lever fromthe neutral position putsthe speed gear(Q, fig. 174) into operation.

(9) LOADING TROUGH. A loading trough(fig. 106,and A and Q, fig.107) on which the projectilesand powder charges areconveyed fromthe yammer to the gun is attached to the frontend of the yammer.

(10) INrERLvCKINO DEVICE. To prevent accidentalforward move-ment of the ammunition before the loading trough is lowered to itsproperposition in the gun breech,an interlockingdevice (C,L and M,fig. 108) is provided. This arrangementprevents any upward move-ment of the control lever aboveneutral position (N, fig. 7.07) until. thetroughhas been lowered to its seat in thegun breech.

(11) LOADING ANGLE. Thecorrect loading angle for the gun is 3degrees, 48 minuteselevationand this angle ofelevation mustbe main-tainedwithout variation when the gun isbeing loaded.Failure to placethegun at this loading anglewill result in undue strain upon the load-ing trough due toimproper seatingof the troughend in the gun breech(fig. 1.12).This positionis determinedby the loading positionpointer(P, fig. 73).

(12) AMMUNITION. Projectilesare delivered to theyammerby meansof ammunition trucksor by overhead trolley (fig.113) (dummy projec-tile shown). Powder charges are conveyed by meansof ammunitiontrucks only.

(13) AMMvNITioN TRUCKS. Trucks forconveyingammunition areprovided with aprons extendinglongitudinally along their sides.Theseaprons arehinged to thetruck body and areutilized asbridges to insuresafe transfer of the ammunition fromthe truck to the rarnmer trough.

(a) Safety dogs designed to preventrolling of the ammunition dur-ing transit are provided onthe truck bed. These dogs maybe releasedby hand power, permitting thetruck to be unloaded from either side.

(b) Bumpers assembledto theright and left side frames limit theforward movement ofthe truck.

(14) SH0T TONGS .

(a) When projectiles are transported by trolley they are broughtfrom the magazine suspendedin ammunition shot tongs (fig. 113) anddelivered directlyto therammer trough . Chain falls (fig. 113) are em-ployed forraising and loweringthe projectiles.

(b) Description and functioning of ammunition trucks and shottongs is outlined under "Tools and Accessories for theCarriage ."

(a) Elevation of the gun by power is accomplished by means of all

a°elevating motor (hg. 69). acting througha hydraulic speed gear. This

speed gear transmits power by means of a vertical drive shaft (N, fig.r

7() through a train of gears connecting with the elevating rack. To

F hl (P fi 74) thlioperateby power, the clutcever,g . neare eevatng hand-

wheel is moved to engage the clutch lever handle plunger in the outerhole in the clutch lever arc (G, fig. 74). Placing the lever in this positionengages thepower clutch in the train of gears to the elevating pinion(F, fig. 87, and L, fig. 88) and rackwhich operatestoelevate or depress

f the gun.The motion of elevation or depression is controlled by the oper-ator at the follow-up control handwheel (M, fig. 74, and J, fig. 68).

(6) Control of Speed Gear. The speed gearis stopped automaticallybefore the extreme limit of elevation or depression is reached 1- eans-of elevation and depression cams (H, fig. 72, and X, fig. 87) attached tothe right elevating rack. When the cams strike the cam lever (T, fig. 72,and M, fig. 87), amovement of the connected parts takes place whichcauses the control shaftstop clutches (fig. 68) to come into engagement,thus stoppingthe movement of the control shaft which in turn stops theactionof the speed gear. The clutches may be released by pressure fromthe knee on release lever(T, fig. 74).

DESCRIPTION AND FUNCTIONING

TM 9-471

(s) Elevation by hand from the right side of the mount (slow- ...motion) is performed bymoving the clutch lever (F, fig. 74) to theposition marked "HAND" on lever are (G, fig. 74). In this position,rotation of the handwheel (E, fig. 74) transmits motion to the elevatingrack through the same train of gears as is used in power elevation. Oneturn of elevating harndwheel counterclockwise tlevates gun 56.509minutes.

(h) Elevation by hand on the left side (fast-motion) is accomplishedby means of the elevating crank (fig. 136). When the hand elevatingcrank is being used the clutch lever must be in "HAND" position on theclutch lever arc on the right side of the mount . One turn of the crank. counterclockwiseelevates the gun2 degrees 56.897minutes, (The crankmust beremovedwhen elevating by power.)

(3) ELEVATION POINTER .

pressionis shown by the position of the shoulder of this nut with relation ,X

to the spring indicator (B, fig, 83). If the nutis tightened so that theshoulder is below the indicator the compression of the spring is in-creased.Normally this shoulder should be flush with the spring indicatorwhen thebrake is locked.

(d) The brake band adjusting rod brackets (K, fig. 86, and C, fig.85) anchor oneend of each brake band to the adjacent gear plate (G,fig. 68, and A, fig. 86). One ofthe nuts (fig- 85) provides an adjustmentof the brake band for wear, the other nut locks this adjustment .

(6) ELEVATING Bu3 :FExs. The elevating buffers (figs. 87 and 88)absorb the shock which results from sudden stopping of the gun andothertipping parts atextreme elevation or depression.

(a) These buffers areself-contained units, bolted to the lower edgesof the right and left side frames so asto make contact with the elevatingracks (g, fig. 87, and Q, fig. 88). Buffer levers (W, fig. 87, and H, fig. 88)attached to the buffer housingbrackets (V, fig, 87, and S, fig. 88) extendoutward in the path of the elevating and depressing stops on the ele-vating racks.

(b) As therack reaches its maximum limits in either direction the 17stops contactthe buffer lever stopping the rotation of the tipping parts . X" .-This action is cushionedby theBelleville springs (Q, fig. 87, and B, fig.88). Any pressure on the rack end of the buffer lever resulting fromeither anupward or downward movement is transmitted to the other endof the lever, causing sompressiorzof the Belleville sprin Yildifgs.engothe springs under pressure absorbs the shock resulting from suddenstopping ofthe tipping parts.

(7) RANGF- DATA INDICATOR. An elevation data indicator (S, fig. 74),located on the right side of the carriage near the elevating control hand-wheel, enables the gunner to set the gun to the correct angle for anygiven range (fig. 135). The range data indicator contains two sets ofpointers, one operated electrically and one by mechanical means. Theelectricalpointer is controlled and operated from an off-carriage stationin conjunction with the range finding mechanism . The mechanicalpointer is operated through a drive mechanism (fig. 89) and is drivenfrorna rack (C, fig. 89) attached to the cradle. As the tipping parts areelevatedor depressed the rotation is transmitted through the train ofgraysof the drive mechanism to the mechanical pitfh ionero tendicator Itshowingtheposition of the gun in elevation.(a) A zero adjusting device (fig. 89) is located in the indicator drivererchanismwhich provides a means for setting the mechanism in properrelationto theposition of the gun in elevati on.

(6) CAM TRippmo DEVICE. When the gun is being elevated bymotor power and the approximate limitof elevation or depression isreached, cams (X, fig. 87, and H, fig. 72) on the right elevating racknear its upperand lowerendsengage with a cam lever (T, fig. 72) onthe inside of the right side frame.

(a) This device, consisting of a series of cranks, levers, rods andsprings, acts to engage clutches (fig. 68, and N, fig. 69) located onthecontrol handwheel shaftand to prevent further elevation or depressionof the gun.

Figure 144--Extending Loading Trough into Breech Opening

RA PD 38802

(b) When these clutches are in engagement it is not possible tocontinue movement ofthecontrol handwheel in the direction in whichthe gun has been moving. Operation of the handwheel will then be pos-sible only in the opposite direction.

(7) CLUTCH. RELEASE . To facilitate release of the clutches employedto stop the elevating gearing at extremes of elevation and depression,a knee operated lever (T, fig. 74) is provided which enables the operatorto throw the clutches out of engagement in the event of inability toeasily release the mechanism by reversing the movement of the controlhandwheel. When the clutches are released the gun may be elevated ordepressed, by . power, sligntly beyond the position determined by theautomatic action of the cams and cam levers.

(fig. 138, and L, fig. 93) on the leftside frame at "HAND" position,assemble the traversing cranks (fig. 139, and F, fig. 94) on the crank-shafts (G, fig. 94) and lockthem inplacewith the splitpins providedfor the purpose. Traverse the mountto the rightand left by means ofthe cranks and note that the mount traverses freely. Rotate themountto its extreme right and left position within prescribed limits. The mountmay be traversed 72 .5degrees tothe rightand left of the center lineof fire.

(a) Before attemptingto traverse the mount by either hand or elec-tric power, the traversing multi-disk friction device must be set withproper friction on the slipping parts to prevent injury to the traversingmechanism. This adjustment will be made only under the supervisionof trained Ordnance Department personnel (fig. 141).

(2) LIMITS of TRAVERSE. Care must be exercised when approach-ing the limits of traverse to slow down the movement of the rotatingmass. The following precautions mustbe observed

(a) The carriage shouldnever betraversedmanually soasto comeinto contact with the positive stop under full power.

(b) The limitswitch button and the start buttonat the traversingpush-button station (fig. 156), or the manual resetleveratthe motorcontroller, should notbeoperated unless the speedgear control indicatordial (C, fig. 143, and R, fig. 96) is set at zero.

(G) When the gunistobetraversed beyond theazimuth limitsoftheelectric limitstop, the carriage should berotated manually unless careistaken to use the least possible speed gear stroke thatwill movethe car-riage in azimuth.

(3) SLOW-moTIDN HANDWHEELS. Manipulate the slow-motion trav-ersing handwheels (fig . 140, 3, fig. 93, and U, fig. 95) on the- right andleft sides of the mounttoascertain thatthe slow-motion train of gearingis in proper working condition.

(4) TRAVERSING CLUTCH SHIFTER. Operate the traversing clutchshifter lever (fig. 138, and N, fig. 94),located onthe leftside frame, toseethat it moves the traversing clutch inand out of engagement withoutinterference_ If necessary, rotate the slow-motion handwheel, afterpress-ing down the foot treadle (fig. 140), to bring the teeth ofthe engagingparts into proper alinement .

(5) FooT TREADLES. Test the operation of the slow-motion foottreadles (M, fig. 99) to insure that the treadle counterweights (L, fig.99) will return the treadles to the "UP"position whenreleased . and thatthe treadle latch plate (N, fig. 99) will holdthe treadle in "DOWN"position until kickedloose by the operator.

(b) TRAVERSING CONTROL INDICATOR. With electric current to thetraversing motorshut of, testthe traversing indicator control parts bymaneuvering the traversing control handwheels in the operator's cab(T, fig. 94) at the leftslow-motion handwheel to insure free operation

186

Page 124: 16-Inch Seacoast Gun

OPERATION

TM 9-471

of the mechanism. This test will be made only after the operator isassured that the traversing motor is not running.

k. Traversing by Electric Power . Traverse themourntwithin pre-scribed limits byelectric power to insure that all working parts operateproperly . The followingsequence of operations will be observed:

(1) Check all push-button stations to insure thatthe switches areopen by testing the spring return action ofthe switches at start and stoppositions.

(2) Note that the handles on all motor controllers are at "OFF"position and that the traversing indicator dials are at zero position onthe traversing control gear case.

(3) Remove caps (3, fig. 150) fromthe power cable loop receptacles(A, fig. 149, and E, fig. 150) atthe recess inthe emplacement andon theinclined surface ofthe racerand assemble the loop cable in place.

(4) Attachthe plug retaining nuts (D, fig. 150) on the cable to thereceptacles on theracer and emplacement.

(5) Assemblesupporting chains (F, fig. 149, and Q, fig. 150) to thebrackets (U, fig. 1.49,and. M, fig. 150) on the racer and emplacement.Note that the supporting chain located nearest to the receptacle on thecable must be assembled to the chain bracket onthe racer.

(6) In order to traverse the mount by "POWER" the traversingclutch shifter lever (fig_ 138, and N, fig. 94) must be set at "POWER"position and the control switch at the traversing push-button station(fig. 156) mustbe pressed intostart the motor. The traversing controlindicator MUST show that the traversing control detent is in neutralposition before the pushbutton at the control station is used to startthe motor . Failure toprovide for this sequence of operations will resultin an overload on the motor.

(7) Speed and direction of traverse is controlled by means of thetraversing control handwheel (fig. 142, and T, fig. 94) located beneaththe left slow-motion handwheel Q, fig. 93), and also by the controlhandwheel (D, fig. 103) and (fig. 143) in the operator's cab.

(8) The direction of traverse is determined by manipulating thecontrol handwhees in the direction indicated bythe arrows on the indi-cator dials (Q, fig. 93, and C, fig. 103).

(9) TRAVERSING LIMIT SWITCH. The limit switch button at thetraversing control push-button station (fig. 156) is designed to reestab-lish operation of the motor when it is automatically shut off by contactof the traversing limit switch (M, fig. 104) connected to the racer, withthe limit switch stop rail (B, fig. 104) attached to the base ring. To re-establish electrical contact the limit switch button at the traversing push-button station must be pressed in and held in thatposition until themount is traversed to a point where there is no longer contact betweenthe wheel on the control switch and thelimit switch stop rail. In orderto activate the motor the starting button must be pushed while the limitswitch button is held in operating position .

(a) Before pressingthe limitswitch button and the starting buttonwhich activates the motor, be surethatthe position arrow on the trav-ersing control gear casepoints tozerograduationon the dial indicator.With the motor running, the mount may now be traversed to the rightor left, asrequired by operating the controlhandwheel either undertheleft slow-motion handwheel or in the observer's cab.

(b) Ifitisdesired to continue rotation inthe same direction beyondthe,point where the limit switch device has shut off the electrical power,it will be advisable to continue this movement by hand power usingslew-motion handwheel to bring the gun to further rightor left positionas may be desired. (See Limits of Traverse, par. 9 J (2) .)

(c) If it is desired to reverse the movement of the rotating,parts,electric powermay be used andthe direction of movement will be con-trolled by manipulation of the traversing control handwheel. If handpower is to be used at any time to traversethe rotating parts, the clutchshift lever on the left side frame must be set at "HAND" position.

(lfl) TRAVERSING DATA RECEIVER. Observe the action of themechanical traversing dial on the data receiver (K, fig. 94) while themount is being traversed to insure that the dial moves smoothly. If thereis any indicationofmalfunction of this device, the matter must be calledto the attention of Ordnance Department personnel for correction. Noadjustment of this device will beundertaken by the using service.

a. To loadthepiece, set the gun at 3 degrees, 48 minutes elevation.Thisangle willbeindicated by theloading pointer (P, fig. 73) locatedon the right side frame which must be set to agreewith the loading anglemarking onthe right elevating rack (L, fig. 73).

(2) RzcUPERATOR CYLINDERS. Check recuperator cylinders (figs.50and 51)foroil leaks which may occurat oneormore of four points onthecylinder-i.e .,betweenthefront endof thecylinder (C, fig. 50) andcylindergland (G, fig.50), between gland(G, fig.50) and gland (L, fig.50), between the forward endof theplunger (AE, fig.50) and plungergland (AM, fig.50), or betweenplunger gland (AM, fig.50) and outersgland (AN, fig.50).

16. FILLING DEVICES .a. Recoil Cylinders.For filling the recoilcylinder a fillingfunnel

(G, fig. 48), which iscarriedin the armament chest,is attached toabracket (E, fig.48) on therightside of the cradle.Afitting onthe lowerend of the flexibletubingof the funnelis attached to the fillingvalve(fig. 48) which is locatedat the bottom andto the rear ofthe recoilcylinder.Aplug cap (K, fig. 48) on tee(J, fig. 48) in the expansionchamber piping providesfor ventingof therecoil cylinder duringthefilling operation.

b. Recuperator Cylinder.A filling funnel (fig.120) used forfillingthe recuperator cylinders with liquidiscarried inthe armament chest.When thisfunnel isused the oil flows into the recuperator cylinders bygravity and there must be neither liquid nor airpressure in the cylinders.The filling funnel isattached atthe top of the liquid valves(fig. 54)after the fillingcap (E, fig. 54) has been removed.

(1) Aliquid pump (fig.55) ismounted onthe left side ofthecradleand providesa meansof replenishing theliquid in the recuperatorsafter they have been charged.

(2) Acompressed aircylinder tubing (fig.116)used for fillingthe- recuperators withair is carried with accessories for the carriage.This

tube iscoiled formechanical flexibility andits ends areattached totheair maneuvervalve (B, fig. 44) and (figs_ 56and 116) and totheportablecompressed air cylinder.

CARE AND PRESERVATION

17. FILLING HYDRAULICSPEED GEARS WITH OIL.

a. Speed gears must be completely filled with air-free oil. Thepresence of air in the oil will prevent the proper functioning of thedevice, To insure freedomof air from the oil chamber, each motor speedgear is provided with an oil expansion reservoir which must be keptfilled to one-half capacity at all times.

b. Examination of the oil level in the oil expansion reservoirsforthe elevating, traversing and rammer speed. gears will be made at fre-quent intervals. If the oil is found to be below the required level it willbe replenished.

18. AIR COMPRESSOR .

a. General. The compressor is equipped witha crankcase (H, fig.59) which is kept filled with oil to a level determined by the oil gagelocated in the oil well of the crankcase. A drain plug (R, fig, 58) isprovided for draining the oil from the case. The compressoris alsoprovided with a moisture trap and air filters (fig. 62, and S, fig. 58)which operateto care for condensation in the line leading to thepres-sure switch and magnetic unloader. The trap hasa drain cock (fig. 62)at the bottom fordrawing off accumulated moisture andisalsoprovidedwith an air filter (fig. 62) atthetopforfiltering the air to the controlsystem.

b. Filter Elements. The filter elements may be taken offfor clean-ing by removing the wing nuts (fig. 65). CAUTION: The filter elementmust be washed in light oil. The use of kerosene or gasoline is prohibited.

e. Relay Vales. Occasionally foreign matter accumulates in theunloading relayvalves (fig,63, and Kand S, fig. 58) and underthis con-dition the unloadingsystem will not function properly. Thevalves maybe cleared by pressing in the plunger of the magnetic unloader (fig. 128)in section III. This action releases the airinthe unloading system andcleans the seats of the relay valves.

(1) The unloading systern is provided with an oil priming cock(fig. 64) which is used to prime the relay valves when the valve seatsare dry. Dryness ofthe valveseatscauses f.Allure of the unloading systemto operate until the seats have been lubricated. The oil priming cockis provided with a dust cap which moves with the lever in opening thevalve.

d. Lubrication . The compressor is equipped with a pressure systemfor lubrication. When the oil pressure gage (J, fig. 66) registers 35 itindicates proper lubrication of the compressor. An oil filter (fig. 67)insures a flowof clean oil to the compressor parts .

197

TM 9-47117-18 _ '.

e. Operation. When the compressor is operated "CONTINU-OUSLY" the unloading system holdsthe three compressor cylindersuction valves (fig. 65) open, thereby interruptingthe pumping action `--while the compressor continues in motion . The unloading system releasesthe three compressor cylinder suction valves for normal operationwhen

(2) To check the oil level:(a) Removethe oilgage andwipeitoff witha clean rag.

(b) Reinsert theoil gage in theoil well and pressdown asfar aspossible.

(c) Remove theoil gage and observeto what extentthe gagehasbeenwet byoil. If the oil reachesthe uppernotch ofthe oilgage,thecompressor hasample oil;but if the oil doesnot reachthe lowernotch

of thegage,oil mustbe added.

19. LUBRICATION INSTRUCTIONS.a. General. The following lubricationinstructions forGun, 16-in .,

information and guidance of all concerned, and supersede all previousinstructions. Materiel must be lubricated in accordance with the latestinstructions contained in Technical Manualsand/orOrdnance FieldService Bulletins.

b. Except when lubricants areused to protect metal surfaces fromrust or corrosion, lubricants are always appliedto metal surfacesthatrub together. When even the tiniestparticles of dust or grit get into thelubricant between these rubbing surfaces, scoring andextremelyrapidwear occurs. For this reason cleanliness should be emphasized. Dirtshould not be allowed to accumulate onthe weapon. Where these rub-bing surfaces are not closed off and lubricated by fittings or holes thelubricant should be thoroughly cleaned. off and replaced with clean lubri-cant at the intervals given in the Guide following . Before removingplugs from holes and covers from fittings and before lubricatingopenholes, thoroughly clean the adjacent surfaces to prevent dirt fromentering.

c. Lubricating fittings are painted red for ease in locating. Oilholesare encircled by red rings.

d. Lubrication Guide. Lubrication instructions for all points tobeserviced by the using arm- are shown in War DepartmentLubricationGuides Nos, 148-1, 148-2, 148-3and 148-4, whichspecifythetypesoflubricants required and the intervals at which they are to be applied.The following lubrication instructions contain the same informationas the guide. Guides from which data are reproduced are 10- x15-inchlaminated charts which are part ofthe accessory equipment of eachpiece of materiel, Data contained in the Lubrication Guides is taken ,Yfrom Technical Manuals, and are binding on using troops.

e. Points to he Serviced and/or Lubricated by Ordnance 11ain-teraancePersonnel at Time of Ordnance Inspection.

(1) TRAVERSING GEAR CASES. To remove accumulated sediment inthe gear cases, the units will be disassembled once a year, and allinterior parts washed with SOLVENT, dry-cleaning. Dip gears inOIL, engine, seasonal grade, and reassemble . Fill cases sufficiently toinsure that gears are partially submerged. T -

f. Cradle Trunnion Bearings . These must be kept thoroughly `-lubricated at all times,

g. Lubrication frequencies as outlined intheLubrication Guide arebased upon continuoususe of the materiel with frequent firing. When,however, the materielhas been unusedfor a considerable length oftimeall moving parts will be thoroughly lubricatedbefore maneuveringoper-ations are undertaken.

h. When cleaning sliding orrevolving parts of the gun and carriage .care mustbe exercised toremove all dirt, residue or other foreign matterfrom the partsbefore lubricant is applied.

TM 9-47119

16-INCH SEACOAST GUN MATERIELGUN MK. II MI; RARSETTE CARRIAGE M4

i. Moisture and grit accumulate in the trunnion bearings. Therefore,they will be cleaned oncea year. They will also be cleaned beforechanging grades of lubricant. Use following procedure:

(1) Remove trunnion covers and clean all grease from bearings,housings and covers with SOLVENT, dry-cleaning.

(2) Thoroughly drybearings and housing and pack bearings withGREASE, O.D ., seasonal grade.

(3) Replace trunnion covers andfill housings with GREASE, O.D .,seasonal grade.

j. Waterbury HydraulicSpeedGears . The oil used for a hydraulicmedium in Waterbury speed gears becomes contaminated with water,dirt and oxidized oil that combine to form sludge . Although the systemis drained, and fresh oil supplied at the specified intervals, agood portionof this sludge remains in the mechanism. To prevent sludge fromaccumulating, the machine will be disassembled and cleaned onceeachyear.

k. Traversing Reduction Gears. Twicea year, these gears will bewashed with SOLVENT, dry-cleaning, and coated with GREASE, O.D .,seasonal grade.

m. Reports and Records.

(1) REPORTS. Iflubrication instructions areclosely followed, properlubricants used and satisfactory results arenot obtained, a'report willbe made to the ordnanceofficer responsible for the maintenance of themateriel.

(2) RECORDS.A complete record of lubrication servicing will be keptin the Artillery Gun Hook for the materiel.

8. SAFETY PRECAUTIONS.

DESCRIPTION AND FUNCTIONING

a. The following safety precautions are enjoined upon all persons

handling the gun, carriage and rammer:

(1) Be assured that the recoil parts Jock (figs. 45 and 130) is in

lockedpositionat all times exceptwhen the gun is to be fired.

(2) Be assured that the lock is open whenthe gun is fired.

(3) Do not attemptto operate the various mechanisms of the gun,

carriage and rammer by electric power until these mechanisms have been

first operated by hand power to insure that they are in proper working

order.

(4) If there is evidence of malfunctioning of any of the parts, do

not persist in operatingtheparts until corrections have been made.

(5) Avoid excessive speed in traversing the mountwhen reaching

the limits of traverse to avoid bringing the gun forcibly into contact

with the emplacement.

(5) Do notuse excessive speedwhen approaching thelimits of ele-

vation and depression to avoid undue shock to the moving parts.

9. OPERATION OFTHEGUNAND CARRIAGE .

a. Prepare the piece for action in accordance with the followingprocedure

(1) RECOIL PARTS LOCK. See that the recoil parts lock (fig. 45) is

assembled with thenut (A, fig. 45) securely screwed ontothe stud (F,fig. 45).

b. Preparing the Gun.

(1) Remove breech and muzzle covers. Lubricate all moving partsof the gun and mount in accordance with requirements as outlined inLubrication Guide. See that all oil reservoirs or retainers are suppliedwith sufficient quantities of proper lubricant.

(2) REMOVING COMPOUND, RusT PREVENTIVE. Remove allCOMPOUND, rust preventive, from gun breech, breech mechanismparts and other exposed finished surfaces of the gun and carriage.

(3) CLEANING BREECH MECHANISM. Open the breechblock by re-leasing the operating lever latch (X, fig. 14) fromthe upper end of thebreech operating lever (F, fig. 13) bringingthe carrierto full open posi-tion (fig. 14). Complete the operationof thoroughly cleaning all partsof the breech mechanism. Particular care must be exercised to insurethatthe channel throughthe obturator spindle (J, fig. 11) is free fromoil, grease, or dirt of any kind.

(4) CLEANING GUN BORE. Using the borescraper, bore sponge andchamber sponge, remove all preservingcompoundand oilfromthe boreand powder chamber of the gun (fig. 14). Cleanthe bore and chamberwitha sodaand water solution as prescribed, andthoroughly dry allinterior parts of the gun.

(5) OPERATING BREECH MECHANISM. After ascertaining. that theair compressor is inproper working condition asoutlined ind,below, thebreech mechanism should be operated in the following manner:

(a) Test efficiency of the compressed air systemby first shutting offthe flow of air through the breech closing valve (fig. 26, and Y. fig. 13).

(b) Open thegas ejector valve (fig. 25, and R, fig. 13) to permit flowof air into gun breech.

(c) Close gas ejector valve and open the closing valve gradually,allowing air to enter the closing cylinders slowly to avoid too rapidclosing of the breech mechanism.

(f) Close valve in the maneuvering valve body (fig. 116) and thevalve on the portable cylinder.

(g) Disconnectthe filling device fromthe empty cylinderand attachit to a full cylinder.

(h) Reopen thevalveinthe maneuvering valve body (fig. 116) andcontinue torepeat thisoperation untilthe airpressuregage Q, fig. 55)shows apressure of 1,700 pounds per square inch.

(i) The piston rod nut washer (U, fig. 50) should now coincidewiththe zero markings on the liquid indicators (AP, fig. 50) and the liquidpressure gage (W, fig. 55) at the liquid pump should show a readingof 1,842 pounds per square inch.

(j) When this condition is evidenced theair and liquid pressure inthe cylinderwill be in balance.

(k) Now close all valves, remove the filling device and replacemaneuvering valve plug (L, fig. 56).

(1) To replenishpressuresin the recuperator cylinders madeneces-sary by escape of air or in the initial filling of the cylinders the pro-cedure outlined above will be followed.

e. Filling and Replenishing Recuperator Cylinders with Liquid.Having in mind the necessity of keeping the prescribed quantity ofliquidin the cylinders at alltimes, air pressure will not beapplied untilthecylinders have been filled with liquid. The sameliquidis to be used asis used in the recoil cylinder.

(1) LIQUID PRESSURE IN RECUPERATORS. Examine recuperatorliquid gage (W, fig. 55) at the liquid pump toascertainthat the pressureregisters 1,842 pounds per square inch. If the pressure is below the pre-scribed reading of1,842 pounds the liquid pump will be operated untilthe required pressure is indicated on the liquid pressure gage dial.

(a) Examine the position ofthe recuperator piston rods. With airpressure of 1,700pounds and liquidpressure of 1,842 pounds the circum-ferential line on the piston rod nutwasher (U, fig. 50) should coincidewith zero marking on the graduated liquid indicator (AP, fig. 54)attached to each piston rod outer gland (AN, fig. 5Q). Should there beany variation inthe longitudinal position ofthepiston rods it indicatesa lack of uniform liquid pressure in the recuperator cylinders. To correctthis condition check the liquid pressure in each individual recuperatorcylinder separatelyby opening the pressure filling valve (J. fig. 118)in the valve body ofeach recuperator. Thiswillallowthe liquidpressurein each individual cylinder to register on the liquid pressure gage. Ifthe liquid pressure is below 1,842 pounds per square inch inany cylinder,the pressure will be increased bymeans ofthe liquidpumpuntil allcylinders show pressure of 1,842 pounds per square inch.

(b) Theliquid pump (D, fig. 44) and (fig. 55) is used to replenishthe liquid supply inthe three recuperator cylinders and will beoperatedto replenish each one of the recuperator cylinders independently.

OPERATION

(c) To replenish liquid in therecuperatorcylinders remove the fill-ing cap (D, fig. 55) in the -pump cover, fill the pump with liquid (fig.119) and replace the cap. Then open the pressure valve (fig . 118),attached to the particular cylinder to be filled, bybacking off thevalvestem approximately three-quarters of an inch (six turns). Now applypressure by operating the lever of the liquid pump forcing liquid intothe recuperator cylinder until the index mark onthe piston rod nut

(d) When opening the pressure valves (J, fig. 118) for replenishingrecuperator cylinders with liquid DO NOT OPEN the.hexagon headgravity filling valve (D, fig. 118) OR REMOVE cap (E, fig. 118) whilethe recuperators are under pressure, as thehexagon head filling valveand cap arefor gravity filling only.

(e) Thepiston rodnut washer (U, fig. 50)should never he allowedto bear against theouter gland (AN, fig, 50). So long as a one-half inchspace is maintained between these parts the floating piston and rod willbe in balance and willhave notensile stress broughtupon them.

(f) Pressure of liquid in any recuperator cylinder should never bepermitted to fall below a point where the piston rod nut washer movesto the front a distance greater than five inches from the face of theouter gland.

(g) Initial filling ofrecuperatorcylinders (fig. 120) with liquid willbe done in accordance with the following procedure-

]. With. no compressed air in the cylinders and with recuperatorassembled at 2-degree depression, set piston rod so that the markingon the piston rod nut washer (U, fig. 50) coincides with graduationmarked zero on liquid indicator (AP, fig. 5Q).

2. Remove dustguards that house therecuperator mechanism.

3. Remove capfromvalvebody (G, fig. 118) and attach specialfilling device designed forfilling cylinders with liquid. (Thisdevice iscarried in the armament chest .) Unscrew filling valve (D, fig. 118) aboutone-halfinch (approximately seventurns) and pour liquid into funnel(fig. 120).

4. In filling the recuperator cylinder withliquid, the liquidshouldbe poured into the funnel graduallytopermit the air to escape pastthe stream of liquid while the cylinder is being filled (fig. 124). After

_ filling, allow sufficienttime for all air to escapefrom the cylinder beforeclosing the valve stern.

5. Eachcylinder will be filled individually in the same manner.

(B, fig. 66) tosee that the air pressure registersbetween 135 and 155pounds per square inch. Examine the oil pressure gage (3, fig. 66) toinsure that proper lubrication for the compressor parts is being main-tained. The gage pointer should indicate pressure at 36 to 35 on thedial. Ifoil pressure gage shows less than minimum pressurethe mattershould be called to the attention of the ordnance personnel who willmake adjustments-as indicated in figures 125 and 126.

(1) The interstage cooler vent cock (L, fig. 58) must be in openposition when the compressor is operating automatically. The cock maybe closed when the compressor is operating continuously.

(2) If there is leakage at the relay valves (K and S, fig. 58), theunloader fingers (fig. 65) will fail to release the three intake valves(Fig. 65) and pumping action will not be reestablished at the prescribed

the blank pressure plug holes in the mushroom head ofthe obturatorspindle. Arod may be inserted through the two eyes, if desired, to liftthe obturator spindle for insertion into breechblock or for removingfrom breechblock.

b. Removable PrimerSeat Wrench Eyebolt. The removable primerseat wrench eyebolt (fig. 194) is about3 inches long and l4 inch in

diameter. It is used to insert the locking pieceinthe removable primer

seat wrench (fig. 194).

71. FUNNELS.

a. Recoil Cylinder Filling Funnel. The fillingfunnel assembly (fig.190) which contains a funnel, abronze ferrule, a flexible copper tube,anipple, a nut and washer, is used to fill the recoil cylinder. The funnelis hooked on abracket on the right side of the cradle. This bracket keepsthe funnel higher than the recoil cylinder and the expansion chamber sothat the recoil cylinder can be filled with liquid and anyair that mightremain inthe cylinder isforced up into the expansion chamber.

b. Counterrecoil Cylinder Filling Funnel . This funnel assembly(fag. 190), which consists of afunnel, ferrule, coupling, a shortnipple,awasher and nut, is screwed over the filling hole of the counterrecoilcylinder and isused for pouring liquid into the cylinder.

72. GAGES.

a. Propelling Charge Gage. This gage (fig. 191) is made fromaV2-inch brass rod which is shaped to form a truecircle, the diameter ofwhich is the exact diameter the propelling charge should have. The endsof the rod project outward and are riveted together to form a handle. Thepropelling charge gage is used to determine the maximum allowablediameter of the propelling charge to be used. If the diameter of thecharge is too great, thespacebetweenthe top surface of the charge andthe topof the chamber wall is eliminated, thereby interfering with theprojection of the flame from the igniter to the front of the powdercharge. This conditionsometimes builds up excessive pressures whichprove dangerous when firing the gun. Thisgage,however, is not used onthe "care-igniter type charge ."

b. Thickness Gage. This gage (fig. 191) is afeeler gage which is astrip of spring steel 0.008 inch thick. The thickness gage is used to gagethe clearance between the cradle trunnion and trunnion bed. The cradletrunnions aresupported in floating rollerbearings until thegun is re-coiled. Inrecoil the trunnions seat down in the trunnion bed to take careof the extra load. Therefore, the clearancebetween the cradle trunnionsand trunnion beds must be gaged accurately andthe antifriction devicemust be adjusted for this clearance.

89. PROTECTIVE MEASURES.a. When materiel is in constant dangerof gas attack, unpainted

metal parts will be lightly coated with engine oil. Instruments are in-cluded among the items to be protected byoil from chemical clouds orchemical shells, but ammunition is excluded. Care must be taken thatthe oil does not touch the optical parts of instruments or leather orcanvas fittings. Materiel not in. use will be protected with covers as faras possible. Ammunition will be kept in sealed containers.

b. Ordinary fabricsoffer practically no protection against mustardgas or lewisite. Rubber and oilcloth, for example, will be penetratedwithin ashort time. The longer the period during whichtheyareex-posed, the greater the danger of wearing these,articles. Rubber bootsworn in an area contaminated with mustard gas may offera gravedanger to men who wear them several days after the bombardment.Impermeable clothing will resist penetration morethan anhour, butshould not be worn longer than this.

90 . CLEANING.

a. All unpainted metalparts of materielthathavebeen exposed toany gas exceptmustard andlewisite must be cleaned assoon as pos-sible with SOLVENT, dry-cleaning, or ALCOHOL, denatured, andwiped dry. All parts should then be coated with engine oil.

b. The using arm will decontaminatethe exterior surfaces, the bore,the breechblock assembly, and all porous attachments suchasstraps,covers, etc .,of artillery fieldpieces exposed togas .

c. Ammunition which has been exposedto gas must be thoroughlycleaned before it can be fired. To clean ammunition use AGENT, de-contaminating, noncorrosive, or ifthis is not available, strong soap andcool water. After cleaning, wipe all ammunition dry with clean rags.Do not use drypowdered AGENT, decontaminating (chloride of lime)(usedfor decontaminating certain typesof materielon ornear ammuni-tion supplies) ; asflaming occursthrough the use of chloride of lime onliquid mustard.

91. DECONTAMINATION.

a. For the removal of liquid chemicals (mustard, lewisite, etc .)from materiel, the following stepsshould be taken;

308

Page 212: 16-Inch Seacoast Gun

MATERIEL AFFECTED BY GAS (DECONTAMINATION)

(1) PR o'rECTI VE MEASURES.

TM 9-47191

(a) For all of theseoperationsa completesuit of impermeableclothing andaservice gas mask will be worn.Immediatelyafterremovalof thesuit, athorough bath with soap andwater (preferably hot) mustbe taken.If anyskin areas have comein contact with mustard, ifevenavery smalldrop ofmustard gets into theeye,or if thevaporof mus-tard has been inhaled,it is imperative that complete first-aidmeasuresbe given within20 to 30minutes after exposure.First-aid instructionsare given in TM 9-850 and FM 21-40.

(b) Garments exposedtomustardwill be decontaminated.If theimpermeableclothing has been exposed tovapor only,it maybe decon-taminated by hangingin theopen air, preferablyin sunlight,for severaldays.It may alsobe cleanedby steaming fortwohours. If the im-permeable clothing has beencontaminated withliquid mustard,steam-ing for six to eight hours will be required.Various kinds ofsteamingdevices can be improvised from materials available in the field.

b. Procedure.(1) Commence byfreeing materiel of dirt through the useofsticks,

rags,etc .,whichmust beburnedor buriedimmediatelyafterthisoperation.

(2) If thesurfaceof themateriel iscoatedwith grease or heavy oil,thisgrease oroilshould be removedbefore decontaminationis begun.SOLVENT, dry-cleaning, or otheravailablesolventsfor oilshould beused with rags attached to ends of sticks.

(3) Decontaminate thepainted surfaces ofthe materiel withbleach-ing solution made by mixingonepart AGENT, decontaminating (chlo-ride oflime), with one part water.This solution should be swabbedoverall surfaces.Wash offthoroughlywith water,thendry and oil allsurfaces.

(4) Allunpainted metalpartsand instrumentsexposed tomustardor lewisitemust bedecontaminatedwith AGENT, decontaminating,noncorrosive,mixed one partsolidto fifteen parts solvent(ACETY-LENE TETRACHLORIDE) . If this isnotavailable, usewarm waterand soap.Bleaching solutionmustnotbe used, because of itscorrosiveaction.Instrument lenses maybe cleanedonly with PAPER, lens,tissue,using a smallamount ofALCOHOL, ethyl. Coat allmetal surfaceslightly with engine oil.

(5) In the event AGENT, decontaminating(chlorideof lime),isnot available,materiel maybe temporarilycleaned withlarge volumesof hot water.However, mustard lying injointsor inleather or canvaswebbing isnot removed bythis procedure and will remain a constantsourceof danger untilthe materielcan beproperlydecontaminated.All mustard washed from materielin thismanner liesunchangedonthe ground, makingit necessarythat thecontaminated areabe plainlymarked with warningsigns beforeabandonment.

92. DEFINITIONS .a. The Elastic StrengthPressureis the computed internalgas

pressure ina gun which, at the section under consideration,will stressthe metal insome layer ofthe wall tangentiallyrip to the minimumelasticlimit which isprescribed forthe metal from which the memberis made.

b. The Maximum Pressure isthe maximumvalue ofthe pressureexertedby thepowdergases on thewallsofa gun duringthe firing ofaround.

c. The Rated Maximum Pressure for any ty,pexofgunis thatvalueof the maximum pressure which isspecifiedi the 9orderspecificationsas the upperlimit of average pressure whichmay!te'developedby anacceptablepowder inthe formofpropelling chargeswhich willimpartthe specifiedmuzzle velocity to the specified projectile.

d. The PermissibleMean MaximumPressure forany type ofgunis that valuewhich, should not be exceeded by the average ofthe rnaxi-mum pressuresdeveloped ina seriesofrounds fired under anyservicecondition.

e. ThePermissible IndividualMaximumPressure forany typeofgun is that value which should not be exceededtry the maximumpressuredeveloped 'by any individual round under any servicecon-dition.

93. USEOFPRESSURE GAGES FORSEACOAST ARTILLERY .a. Major CaliberPressure Gages.Forseacoast cannon equipped

for major caliberpressure gages,pressuremeasurements willbe madein all practiceswith serviceor targetpracticeammunition.Coppercylindersshould be changedaftereach shot oftrial fire andmust bechangedafter completion oftrial fire. Coppercylindersneednot bechanged between shots of record fire,

b. Mediurn or Minor Caliber Gages. For seacoast cannon usingmedium orminor calibergages,pressure measurementswill be limitedto shotsof trial fire ..Extreme care must be taken aftereach round toinsurethat no gage remains in the bore.

NOTE: Shouldthere beevidencethat excessive pressuresare beingdeveloped, the firing will be stopped and an investigation made todetermine the cause.

94. EXCESSIVE PRESSURES.

a. Excessive pressuresare considered as follows:

b. When the average of the maximum; pressures developed intheindividual rounds exceedsthe permissible mean maximum pressure, or:

c. When themaximum pressure developedinanyindividual round

exceeds the permissible individual maximum pressure.

95. LIMITATIONS ON USE OF PROPELLING CHARGES.

a. The propelling charges should notbeused in a practice if inthe trialshotsthe mean,of the maximum pressure readings exceeds thepermissible mean for the particulargun, orthe recordedpressure on anyround exceeds the permissible individualmaximum pressure, or if thedifference between the maximum pressures obtained on any two roundsexceed avalue equal to 15 percent of the mean of the group. In thelatter case, the powder isliable todevelop dangerous pressures if firingis continued, or, if not actually unsafe, may give excessive velocityvariation which will be reflected into the range dispersion.

b. The ro eu 9d_X'p pJ XI n Xcharges will notbe used in subsequent practices

if in the record shots the recorded pressure exceeds by more than5percent the permissible. individual maximum pressure. TheS percentincrease is based upon the assumption that the coppers in the gageshave not been changedbetween individual rounds. Under such condi-tions gage readings are usually somewhat higher thanthe pressure onany individual round.

96. MAXIMUM PERMISSIBLE PRESSURE.

a. Maximum permissible pressures forvarious cannonare listed in,columns 4, S and 6 of the table below. Column 3lists the rated maxi-mum pressure for each cannon. This pressure is listed in firing tablesunder the captions "Maximum pressure for which the gun is designed"or "Maximum pressure ."

ELECTRICAL, EQUIPMENTParagraph

a. The electrical equipment for the M4 mount consists of power

circuits, lighting circuits and firing circuits .

(1) Current for power and lighting is brought to the emplacement

by means of. cables which terminate in special receptacles located in

arecess in the emplacement well .

(2) The current is generated at the fortifications by means of Diesel

engine generators.

Current far power and lighting is delivered to the receptacles(3)

on the emplacement through two cables either of which may be used

independently . From this point it is carried througha cable loop and

receptacle on the front segment of the racer to the main distribution

box located under the inner platform on the right side of the mount.

(4) power for the firing circuit is generated on the mount by means

of firing magnetos located on the right and left sides of the carriage.

b. Cable Loop. A cable loop (fig. 149) approximately 24 feet in

length, designed for carrying the power and lighting current from the

receptacle (E, fig. 150) on the emplacement to an identical receptacle

on the racer is provided This cable is of sufficient length to compensate

for the traversing movement of the mount to extremes of position to

the right and left of the center line of fire, without strain or fracture of

the cable and connecting parts.

(1) The cable is provided at each end with three-wire, three-pole,

600-volt a-c commercial receptacle plugs (C, fig. 154) equipped with r",

a retaining nut (I), fig. 150) which must be screwed onto the receptacle

when the loop is assembled.

(2) Hookclamps (A, fig. 150) areassembled onthe cabletowhichchain snap fastenings are assembled . These fastenings are assembled tobrackets on the wall of the emplacement and to the racerbody (fig.149) and are intended to sustain the weightof the cable and relieve thestrain on the receptacle plugs.

(a) The cable endhaving thehook clamp located approximately 18

inches from the cable plug is assembled to the receptacle on the racer_

The end hav#rigthe hook clamp approximately 31 inches from thecableplug is assembled to one of the receptacles on the emplacement.

(3) The ends of the receptacles onthe racer and emplacement are

provided with closing caps (J, fig. 150) to be screwed ontothe ends of

thereceptacles when the plugs are removed.

(4) Duplicate receptacles (fig. 149) are assembled side by side inthe foundation recess at the front of the mount to insure a continuousflow of current tothe emplacement incase one of the cables becomesunserviceable.

(a) Inthe eventofinjury toeither of the main feeder cables, theother may be employed by changing the receptacle plug from the"DEAD" line receptacleto the activeline receptacle continuing an un-interrupted flow of current to the power and lighting devices on themount.

(5)- Afeeder cable and cableloop for conveying electrical data tothe elevating and traversing data receivers is under development andwill be connected to the mount when completed. Location ofthe re-ceptacles for the cable and loop, when assembled, is indicated by dotson figure 149.

c, Main Distribution Box. The main feeder cableleading fromthereceptacle located on the front segment of the racer enters the maindistribution box (G, fig. 151) and (fig. 152) through a watertightcon-nector at the top. The cable is of the three-conductor type, coded red,white, and black. The outside diameter of the cable is 1.67 inches andthe total length is approximately 19 feet. The cableis divided insidethe distribution box and isattached to three parallel bars (K, L andN,fig. 152) from which position the current isdistributed tothe powerandlighting cables.

(1) Four of the cables leading from the main distribution box carrycurrent for power. The fifthcableleads to the mainlightingtransformer(E, fig. 151) and (fig. 153) located under the rightplatform.

30. DESCRIPTION AND FUNCTIONING OF POWER EQUIP.MENT.

(1) MAGrEro6. Either magneto may be used to firethe piece throughacircuit extending fromthe magneto tothe circuit breaker onthe gunbreech. The magnetos should not be operated simultaneously as suchaction might tend to decrease the volume of currentto the firing contactand result in a possible misfire.

(a) Tofirethe piecefromeither sideofthemount, first remove themagneto plug (fig. 132) from the firing plug box,which is attached tothe front web of the side frame on the opposite side. Assemble the plugin the firing plug box on the sidefromwhichthe magneto is to beoperated (fig. 172 is a right sideview).

(2) FIRING PLUGS AND BOXES. Be assured that the firing plug (fig.172) on the endof the firing cord leading from the plug box on the leftside frame is assembled in the plug box (A, fig. 56) on the gun cradleunder the left trunnion. To assemble this plug it is necessary toinserthand and arm in the five-inch opening (fig. 142) provided for this pur-pose in the left side frame near the left trunnion.

(3) CONNECTORS AND CovERs. The plugs assembled onthe firingcords areeach provided with aconnector nut which must be screwedonto the receptacle when the plugs are assembled. Each receptacle isalso provided with a closing cover which must be assembled on thereceptacle whenthe firing plugs are removed.

(4) The.safety firing connactor (fig. 173) connecting the circuit atthe cradle and recoil band operates automatically and requires no handmanipulation .

a. General. Uninterrupted service of the parts of the electricalequipment is vital to the proper operation of the mount and any evi-dence of malfunction of the parts will be given ixnrnediate attention.

(1) POWER EQUIPMENT. The current supplied to the mount forthe operation of the power equipment is 440 volts; and caution will beexercised to avoid making repairs or replacements of parts while thecurrent is turned "ON." Except in cases of emergency, all defects inthe power equipment should be corrected by trained ordnance per-sonnel. It is important that the covers ofallboxes, panels and similarequipment he securely in place to prevent entrance of dirt and moistureto the electrical parts which might result in malfunctioning of themateriel.

(2) LIGHTING EQUIPMENT. Failures in lighting circuits are gen-erally due to defective fuses, loosened terminals, broken or damagedlighting cords or cables, loosened lamps, or improper seating of plugsin their receptacles. When repairs or corrections are necessary on anyof the parts of the lighting circuits, care must be exercised to see thatthecurrent in the defective circuitis shut og while repairs or correctionsare being made. All defective fuses removed fromthe lighting panel,transformers, or other parts of the mount should be destroyed ordefinitely marked to indicate that they are unserviceable.

(3) FIRING EQUIPMENT . Malfunction of the parts of the firing cir-cuit is liable to result in serious injury to the materiel and personnel:extreme care will be exercised to see that any existing defects arepromptly remedied.

(4) MISFIRES. A misfire occurs when the piece fails to fire. Misfire iscaused by

(a) Failure of the primer to fire.

(b) Failure ofthe propelling charge to ignite when the primer fires(c) When a misfire occurs all personnel must remain clearofthe

path of recoil of the piece.(d) The piecemust bekeptpointedat the target or at a safe point

within the field of fire.

(e) If the primer is heard to fire, a new primer must notbe insertecor the breechblock opened untilafter 10 minutes have elapsed. At threxpiration of 10 minutes, insert anew primer.

(f) If the primer has failed to fire, at least three attempts will b{made to fire it before it is removed. If a special. device is available bywhichthe primer can be safely removed by a person standing clearothe path of recoil, the primer may be removed andexaminedafter twtminutes have elapsed sincethe last attempt to fire. When the primehas been removed under the above conditionsinsert a newprimer an(continue firing. If nospecial device as above referred to is available, th,primer must not beremoved or the breechblock openeduntil 10 minutes have elapsed since the last attempt to fire.

TM 9-47139

(1) POWER Loop. Todisassemble power loop, backoff the connectornuts from the receptacles on the racer and emplacement. Unhook thechains from the brackets on the emplacement walland racer, pull theplugs out ofthe receptacles and screwthe covers ontothe receptacleopenings. In order to exclude dirt and moisture from the receptacleopenings, covers mustalways be assembled tightly on the cableloopreceptacles whenthe loopis removed . The chain assembled 18 inchesfrom the end of the loopis attached to the bracket on the racer.Thechain assembled 31 inches from the end of the loop is attached to thebracket in the wall of the emplacement.

(2) MAIN DISTRIBUTION SOX . The cover on the main distributionbox is fastened in place by means of wing nuts. When the cover is openedfor the purpose of tightening terminals or for any other purpose carewill be exercised to see that wing nuts are screwed securely inplacewhen the cover is again closed. The terminals in this box must neverbehandled while the current is "ON" as such action mightwellresult inserious injury to the operator.

(3) MOTOR CONTROLLERS. The construction of themotor controllersis such thatno effort to disassembleor assemblethe controllerswill bemade by the using service, They will be handled by the service only sofarasmay benecessary to reset the controller yoke in the eventofashort circuit as described in paragraph 31 a (9) under the heading"Operation of Power Equipment ."

(4) PUSH-BUTTON STATIONS. Push-button stations will not be dis-assembled or assembled by the using service.

(5) TRANSFORMERS. The covers of the main lighting transformer,sight lighting transformers and plugboxesaresecured in place by ma-chinescrews, When itbecomes necessary to remove these covers for thepurpose of tighteningterminals or for any other purpose, care will beexercised to insure that the covers are reassembled tightly to avoidentrance of dirt ormoisture into the transformersor plug boxes.

(G) SIGRT LIGHTING PLUGS AND PLUG BOXES. Theplugs on theends of the cords leading from the sight lighting plug boxes to the sightsare of special construction and the plugs and boxes are so designed asto enable the operator to assemble and disassemble the plugs in theboxes quickly and with a minimum of effort. To turnthe current "ON"to any lights insert the plug. inthe boxand turn clockwise as far aspossible. To extinguish the light turn counterclockwise as far as pos-sible. To assemble or remove the plug turn to the rightor left until theprojection on the plug is in alinement with thegroove in the box recep-tacle and push into place or withdraw as required.

(7) PORTABLE HAND LAMPS. Plugs on the ends of portable lamp ,cords are of the push varietyand each plug is equipped with aconnectornut which should be screwed ontothe end ofthe receptaclewhentheplug is inserted. When plugs are withdrawn from the receptacles thecovers should be screwed ontothe end of the receptacletoexclude dirtand moisture.

(8) FIRING MAGNETOS. To disassemble eitherfiring magneto ,fromthe mount it will be necessary toremove the firing magneto bracketPram its seat on the handwheel bracket. The card leading from themagneto to the magneto plug box on the sideframeshould not be dis-connected from the magneto. The plug should be withdrawn from theplugbox, and the cordclips removed from the side frame. The entireunit may be dismounted in this manner without disassembling theterminals in the magneto case. Toassemble the unitthereverse ordershould be followed. Excepting for the purpose of replacinglever returnspring orhandle catch spring or for the purpose of assembling or tight-ening terminals in the magneto, the using service will not assemble ordisassemble the parts of the magneto.

(9) FIRING Locx. When the piece is to remain inactive for acon-siderable length of time the firing lock should be removed from thebreech and stored in a safe, dry place. s

(a) To removethefiring lock disconnectthe firing cable (AG, fig.28) from the firing lock terminal nut (N, fig. 28) bytipping theterminalstop (H, fig. 28) and removing the cable terminal (AF, fig. 28) from thenut. Now pull outward on the retracting lever latch (L, fig. 19) andoperate the firing lock retracting lever (P, fig. 19) to openthe firinglock and clear the firing lock safety arc (Z, fig. 19). Now pull downwardon the firing lock operating bar latch handle (fig. 21) and release thefiring lock from the operating bar. Turn thelock counterclockwise onthe obturator spindleone-fourth turnuntil the interrupted threads in thefiring lock are in proper alinement with correspondingrecesses on theobturator spindle and remove the lock .

40. GENERAL.a. Ammunition fortheGUN, 16-inch,Mk. II-Mod. I (Navy), is

of the separate loading type.The loadingof each complete round.intothe cannon requiresthree separateoperations.One, the projectile;two,the propellingcharge;and three,the primer. Thesecomponentsareshipped separately.Armor-piercing projectiles forthis gun are shippedfuzed.

41. NOMENCLATURE.a. Standardnomenclatureis used in this sectionin all references

to specific items ofissue.

42. FIRING TABLES .a. For applicablefiring tables,seethe section ofthisManual en-

titled"References ."

TM 9-47143-44

43. CLASSIFICATION.a. The projectilesauthorizedfor use inthisgunareclassifiedas

armor-piercing,target-practice,and dummy. The armor-piercingpro-jectileis a thick-walledshellfittedwith an armor-piercingcapandfilledwith an explosivebursting charge. Target-practice projectiles areinert castironshot similarin size,shape, and weight to theservice shell,or are service shell. in which aninertfiller is used in place of an explosivebursting charge. Dummyprojectiles consist ofa steel and bronze as-sembly of somewhat similarsize,shape andweight toservice projec-tiles;they are designedfor trainingin handling projectiles andloadingcannon, and are completely inert.

44. IDENTIFICATION.a, General. Ammunition,includingcomponents, is completely

identifiedby means ofthe painting,marking (includingammunitionlot number),and data card or linen data tag.Other essentialinforma-tion ismarked on thecomponents, for example;Onthe projectile,itsweightand the kindof filler;on thepropelling charge,the weightofthe igniter,designation of each section, etc.See figures174to 180, andthe following paragraphs. The muzzlevelocity may beobtained fromthe tag on the propelling charge.

b. Mark or Model.To identifya particular design, amodel desig-nation is assigned at thetime thedesignis classified as an adapted type.This modeldesignationbecomesan essential part of the standardnomenclature and isincluded inthemarking on the item.The presentsystem ofmodel designation consistsof theletter"M" followedby anarabic numeral.Modifications areindicatedby adding theletter"A"andthe appropriatearabic numeral. Thus, "M3AI," indicates the firstmodification ofan itemfor which theoriginalmodel designation was"M3 ."Priorto July 1,1925, itwas thepractice to assign mark numbers.The word "MARK," abbreviated"MK .," was followedbya romannumeral, for example:"SHELL, A. P. MK. XI ."The first modificationofa model was indicatedoythe addition of "MI"to themark number,the second by"MII," etc. In caseof items ofNavyorigin, the modeldesignationoftentimes appears as "MK. II---MOD. I-IN., ..MR. 1I-MOD. 2-IN .,"etc.

e. Ammunition LotNumber. When ammunition ismanufactured,an ammunitionlot number, whichbecomes anessentialpart of themarking,is assignedinaccordance withpertinent specifications.In thecase of separateloading ammunition,such a lotnumber is assigned to,and marked on,eachof the components-projectile,fuze,propellingcharge,and primer-as well asonall packingcontainersand theaccom-panying datacard.It is required forallpurposes ofrecord, includingreports oncondition, functioning,andaccidents, inwhich theammuni-tion isinvolved. To provide forthemostuniform functioning, all ofthecomponents in anyone lot are manufacturedunderas nearly identicalconditionsaspracticable.For example,in thecase ofprojectiles,anyone lotconsists ofprojectiles made by onemanufacturer, loaded by one

16-INCH SEACOAST GUN MATERIELGUN MK. II MI; BARBETTE CARRIAGE M4

manufacturer, and of one weight. Therefore, to obtain the greatestaccuracy in firing separate loading ammunition, successive roundsshould consist of

Projectiles ofonelot number (one type and one weight).

Propelling charges of one lot number.

Fuzes of one lot number.

Primers of one lot number.

d. Ammunition Data Card. A five- by eight-inch card, entitled

Ammunition Data Card because of the information thereon, accom-panies each shipment of ammunition or ammunition components. Inthe case of separate loading propellingchargesa linen tag containingessential data is attached to the charges in place of a data card. Whenrequired, assembling and firing instructions are printed onthe reverseside of the card or tag. Forregulations governing shipments ofseparateloading ammunition components, see OFSB 3-2.

e. Painting anti -Marking.

(1) PAINTING. All projectiles are painted to prevent rust and toprovide, by the color, a ready means of identification as to type. For theprojectiles described herein, the colorschemeisasfollows

Armor-piercing . . . . . . .. . . . . . . . . . . . . . . Yellow; marking in black.

Practice (inert) . . . . . . . . . . . . . . . . . . . . . . Black; marking in white .*

f. Weight Markings.Because itis not practicableto manufactureprojectileswithin thenarrow limitsrequiredfor the desired accuracyof fire, the actual weight of each projectile, to the nearestpound, isstenciled onthe projectilebody inorder that theappropriate ballisticcorrections indicatedbyfiringtables may beapplied.

45. CARE,HANDLING AND PRESERVATION.a. Ammunition componentsare packedtowithstand conditions ordi-

narily encountered inthe field.Projectilesareshipped with agrommetto protect therotatingband, oneprojectileper wooden crateor box.Chargesand primers arepacked in moisture-resistant containers.Sinceammunitionand explosivesare adversely affected bymoisture andhightemperature, the followingprecautions should be observed -:

(1) Moisture-resistant sealsshouldnot bebroken until thearnmuni-tionis tobeused.

(2) Ammunition, particularlyprimersand propellingcharges, shouldbe stored intheoriginal container, ina dry, well-ventilated place,pro-tectedfrom sourcesofhigh temperatures,including thedirectrays ofthe sun.More uniform faring isobtained. if successive roundsareat thesame temperature.

1). Primers must alwaysbe storedin adry place.Prolongedex-posure tomoisture ordampnessmay causemalfunctioning.

Page 285: 16-Inch Seacoast Gun

TM 9-47145-46

c. Explosiveammunition mustbe handled with appropriate care atall times. The explosive elements in primers are particularly sensitiveto undue shock and high temperature.

d. Each of the separate loading components should be free of foreignmatter-sand, mud, grease,etc .--before loading into the gun.

e. Components ofroundsprepared for firing but not fired will bereturned to their original condition and packings, and appropriatelymarked. Such components will be used first in subsequent firings, inorder that stocks of opened packings may be kept ata minimum.

f. Propelling charges will be gaged for maximum diameter withgages furnished by the Ordnance Department. Charges which do notpass through the gage will not be fired .

The sideboard oneach sideofthe truckis raised tovertical positionand locked with the latch handle and pawl when haul-ing a projectile or powder charge. Torollaprojectile off the ammunitiontruck onto the rammer assembly the side board is extended over theparking table of the rammer assembly. The truckhas a filler pieceplaced between the casters and the truck frame to give the truck thecorrect height. The truckis of sufficient length to accommodate thelargest projectile that might be used. The truck is used to serve the gunwhen the emplacement is not equipped with overhead trackage forservice of the ammunition.

63. ARTILLERY GUN BOOK.a. The gun. book (0 .0. Form 5825) is used to keep an accurate

record of the materiel and remains with the piece regardless of- whereit may be sent. It includes records of assignments, the battery com-mander's daily record, and the inspector's record of ammunition, aswell as forms to be filled out in case of premature explosions. This bookshould be in the possession of the organization at all times. It is the soleresponsibility of the organization commander asto the completenessofthe record and as to the whereabouts of the book. It must also containthe date of issuance of the materiel, to and by whom issued, and theplace where issued. If a new gun is installed on the carriage, all datain the oldbook with reference to sights, carriage, etc ., must be copiedinto the new gunbookbefore the old gun book is relinquished.

64. BORE GREASINGDEVICE, 16-INCH, M6.

a. Description. The bore greasing device (fig. 184) consists ofthreeparts

(1) Two friction disks assembled to aspacer.

(2) Asmoothing brush and spreading disk assembly.

(3) Ashaft fitted with aneye on each end. The friction disks serveas guides. They keep the shaft centered and parallel to the bore of thegun. This in turn centers the slushing compound spreading disk, whichis assembled to the brush assembly, and insures aneven pressure ofbrush bristles against the bore of the gun. The friction device and brushassemblyare free to slide on the shaft.

b. Method ofSlushing Bore.

(1) Attach the dragline to the fixed eye on the shaftofthe boreslushing device and insert in the muzzle end of the gun. As the firstfriction disk enters the boreofthe gun,the studs inthe rimofthe disk(fig. 184) will strike against the muzzle face of the gun. These studs areheld out by springs recessed in the disk. Compress the studs by woodensticks held against their ends and insert both disks. Pushthe frictiondisks in, holding the shaft, until the device is in the position shown in(fig. 185-3) i.e ., with the frictiondisk assembly to the extreme endofthe shaftand the otherendofthe shaftextending out beyond the muzzleface of the gun a distance equal to the thickness of the smoothing brushand spreading disk assembly. This will allow the smoothing brush andspreading diskassembly tobefitted after the slushing compound hasbeen applied.

(2) Pack the slushing compoundin the muzzle end of the gun (fig.185-4), taking care to pack solid with no air pockets. Care should alsobe takentoprevent theboreslushing device from beingpushed breech-ward during this operation. In some instances it may be necessary tohold the shaftin order to prevent this breechward movement. _.

(3) Installthe smoothing brush and spreading disk assembly withspreading disk next to the slushing compound (fig. 185-5). At this point,coat the brush bristleswith slushing compound, to insureslushing ofthefirst few inches of the bore at the beginning of the pulling operation.

(4) By means of the dragline (fig. 185-6) pull the bore slushingdevice and slushing compound through the bore ofthe gun_ The forceof the pull is exerted on the brush and spreading disk assembly whichpushes theslushing compound and friction disks through the bore. Pres-sure is built upagainst the compound bythe resistance of the frictiondisks, causing the compound to ooze outaround the spreading disk andfill the grooves. After the bore slushing device has been drawnthroughthe bore to the point where the friction disks enterthechamber, pressureagainst the compound is lost and, to compensate for this loss of resistanceand to slush the last several inches of rifling, it is necessary to holdapole or staff against the friction disk.

(5) The pull onthe dragline may be supplied by hand or, wherespace will permit, by tractor. Always takecaretokeep the direction o¬pull along the axis of the bore. Once the pulling operation isstarted, itisdesirable to continue the pull until the bare is completely slushed. eachstop and start leaves aheavy ring of slushing compound in the bore.
