It is most importantthat a markeddistinctionshould bedrawn betweeninstruction anddrill.

During the former the languageusedshould be as simpleas possible,and the meaningof ui-Il technical termgwhichare necessarymustbe carefully explained.

CHAPTER IV. ----SIGHT TESTS.

The field elinometer, sight clinometer and elevationindicatorshould be testeddaily mind after prolongedfiring.Time alignment tests should be carried out -as often aspossible.

Time remainingtest (crosslevelling gear)should be carriedout when required by a qualified artificer. This test isgiven in time Handbook.

Any adjustmentto optical instrumentsmust be carriedout by a qualified artificer.

Test I.—To test the field clinomneter.Set the clinometer at zero ; place it on the clinometer-

plansand elevate or depressthe gun until time bubble isin thecentreof its run; then turn the clinonmeterendforend. If thebubbleis still in time centreof its run, theclino.meter is in adjustment.

If thebubbleis not in the centreof its run, bring it soby moving the slideror, If necessary,time armmm and slider.Onehalf of thenet readingis the indexerror of -the chino-nmet-er. -

If the bubble cannotbe broughtto the centreof its runby this method, the error of theclinometermay be deter-mined by comparison-with a clinometerof known error.

To eliminate an error, the chinometermust be adjusted

- 58

by a qualified artificer. This adjustmentis given in theHandbook.

Test 2.—To test and adjust the sight clinoineter.With the sight clinometer bracket horizontal and the

sight clinometerreadingzero, time bubble of thesight ciino.mnetershould be in the centreof its run.

Place the sight elinomet-er, set at zero, in its bracketandbringthebubbleto time centreof its runby theelevatinghandwheel. Reverse the sight clinomcter end for end;the bubbleshouldstill be in thecentreof its run.

If the bubble is not in the centre, bring it so by turningthe micrometerhead. Notethe readingand act the micro-meterscalesto half this reading. Bring the bubbleto timocentreof its run by theelevatinghnndwheel.

Alignment tests.

Before beginning thesetests the following preparationsshould be made:— -

(1) Placethecarriageon a firm platform andmanipulateit until it is level transversely(seeiv).

(ii) Selectawell.definedobjectat least-1,500yardsdistantaim which to lay.

(iii) If this distant object cannot be found, set up thetarget testing sights (seediagram)about 50 yards in front(or in rear) of the gun at right angles to time axis of timebore, -

(iv) If the carriagecannot be levelled transversely,timetop of the dial sight carrier and the target testing siglmtssimould be slopedto the sameangleas the carriage.

(v) Removethe striker andfix crosswires at the muzzleof the gun.

(vi) Sot theelevation indicator and time cowl, dial plateand muicroameterscalesof thedial sight at zero.

N0TE.—In practice, tests 4 and S are carried out simul-taneously.

Test 4.—To test and adjust the dial sight br line.

The line of sight throughthedial sight shouldbe parallelto time axis of thebore as regardsline. -

- - 2. THE- DIAL SIGHT AND CARRIER.i. The No.- 7 dial sight. -

The dial sight wimen issued is in correct adjustment,watertight,-and with all the cells andjoints securedwithfixing screws.

It is very unlikely that the interior will require-cl-caning,and the dial -siglmt must on no accountbe takento -piecesexcept by a person in possessionof an OrdnanceCollegecertificatestating that he is cdmpet.entto do so.

The body of thedial sight should be cleanedwith a cleansoft cloth anda little oil, wimich nmust be rubbedoff after-wards, care being taken that time glass is not touched. Nogritty substancesimould be uscd.

The exteriors of eye lens and window should be cleanedwith chamoisleather speciallykept for thepurpose. Greatca-remustbe tn-ken that no oil or greaseis allowed to toueimthe glasses. Fingers, though apparently clean and dry,leavemarks on the lens which will impair the definitionof the sight.

When not in use the dial sight should he kept- 1mm timesight box.

ii The No. 5 carrier. - -

If time sight is loose-in the bracket it may ‘be due to:—(a) The clamping screw headworking out of its -recess,

- makingit impossible to clampup. Time remedyis to pressthe head into time recessand clamp.

(5) The bracketbeingworn or atrained,owing to workingthesight aboutwhen taking it -out of the bracketor over-straining theclampinglever. In this easoaclamptocom-pressthebracketshould be fitted if available; if not, nine

64

side of the bracket should be tapped lightly and evenlywith a hammer by an artificer, with the clamping scre~-loosened.

3. THE BREECH MECHANISM.

I. Generalprecautions.t -

The breecimmechanismshould be dismantledperiodicallyin orderthat it maybe thoroughlycleaned. -

The threads of the bree~hscrew should be free fromburrs; thesemayberemovedby careful filing by anartificer,but no portion of thethreadshouldbe cutawayto removea crack.

The breech should be kept covered up, when possible,to preventdustand grit getting into the breecimfittings.

i. To dismantle the breech mechanism:—

Before removing the mechanismthe breech must beopenedand the breech mechanismswung into the loadingposition. -

vi. To teat the protrusion of the striker

Open the breech, press in the retaining catchand turnthe breechscrew to thelocked position by meansof thebreechmechanismlever. Removethe striker as detailed-

above,anddismantlethecap,trigger andmainspring.Placethestriker body in time guide busim, turn one-sixth

of a turn to time left, pressforward to time fired position,and retain while No. 1 gaugeis applied. The protrusionshould not exceed-11 inch nor be lessthan .~9inch.

Care should be taken to see that therearc no burrs ordirt presentto give an incorrectprotrusion.

4. RECUPERATORAND BUFFER.

- General precautions.

i. Before firing :—

Care should be taken to see that the recuperatorand-buffer a-re correctly charged, that there is no abnormalleakageat thestuffingboxes,that time nut securinghowitzeris correctly locked, that thepiston rod andram arc firmlynuttedup to the front cradlecap,andthat the cut-off gearis in adjustment.

It is necessary to strain the oil before charging timereeuporatoror buffer. -

During severeweatherrecuporatorsa-nd buffers should beprotectedasmuch aspossiblefrom time cold.

Recuperatorand buffer cylinders should be washedoutwith paraffin or hot water to removegrit as opportunities.offer.

Any operationsfor the replacementof worn or defectiveparts whelm necessitatecamptying the recoil system shouldbe carriedout only tinder qualifiedmtmupervision. -

— 5. THE RECUPERATOR. - - - -

1. General precautions ;— - -

- Before the front cradle cap is removed, the gun mustbe securedto thecradleso asto preventit slipping back.

68

If the cradle cap is to be left off for along time, the elevatinghandwheelshould be takenoff.

ii. To charge the i-ocuperator with liquid:—

Securethe gun to the cradle. Discharge any pressure inthe air chamber by removing plug B and opening time by-passvalve C. Removeplug A.

Pour in exactly 6~pints of bufferoil throughhole A.ReplaceplugsA andB, closevalve C, androckthe cradle

so as to free any air lock.Level the cradle longitudinally and transverselywith a

clinometer. RemoveplugsA andB, andfully openvalveC.Allow anyexcessliquid to overflow from hole B. Replace

plugs A andB, andclosevalve C. -

Careshould be taken to see timat the recuporatoris cor-rectly charged,as too muchoil will causeseriousdamageandput time gun out of action. -

III. To charge the recuperator with air :—

Before chargingthe recuperatorwith air it is importantto seetimat thesecuringcollar is in thecorrc~tposition onthe recimperatorrem, In order to preventthe ram frombeing~forced-out to the ream~when underpressure. -

Attach time air pump to the bracketon the right trail.Place the cradle at full depression. Remove plmmg B andattachtheadapterandpressuregauge; connectthepumppipe to theadapter. Open time by-pass valve C and punmpuntil thegaugeregisters610 lbs. persq. in. Close valve 0,disconnecttime pipe from the adapter,and placethe caponthe adapter. Let the pressuredown slowly to 500 lbs. persq. in. by openingvalve C slightly and slackingbacktimecap on the adapter. - -

Wlmen thepressurereads500, close valve C, remove timeadapterwith pressuregaugeandreplaceplug B.

Whenchargingby air bottle caremust be takento openthecock graduallyto avoiddamageto thegauge. -

iv. To test the air pressure ;— -

Placethecradleat full depression. -

Remove plug 13 and attach the adapter and pressuregauge. Blank the outer end of the adapterwith the cap.Open valve C and time gaugeshould-register 500 lbs. persq. in.

If time pressureis correct, close valve C, remove theadapterandgauge,andreplaceplug 13. If time pressureisnot correct, closevalvo C, connectup time air pump, andmakeup the pressureto 500 lbs. -

V. To replenish air pressure lost by leakage :—

Proceed as fm~r charging the recuperator with air, but,before opening valve 0 to admit air to the recuperator, pumpthepressurein time pipeup to 500 lbs. per sq. in.

If time air pressurefalls’below 375 lbs., dischargethe airpressureandchecktime amountof liquid in the recuperatorby levelling thecradle,removingplugsA andB, antiopeningvalve C. -

vi. To empty the recuperator :—

Securethe gun to time cradle,disconnectthe piston rodand recuperatorramn, and remove the front cradle Cal).Dischargetheair pressureby removingplug B andopeningvalve 0, Removethesecuringcollar, recuperatorstuffing-box, throttle valve andspring, andrun off the oil. Rock

vii. To renew the packing in the recuperator glandandthe L rubber in therecuporatorstuffing boxTheseoperationsare similar to timose in Section 6 (iv)

and(v) below,exceptthat theair mustbe dischargedbeforeremovingthesecuringcollar from the rain.

6.TRE BUFFER.

- To fill the buffer :-.-~

- Place the cradle at full depression.- -Removethe filling hole plugs D andE at the rear endof the buffercylinder. Pouroil into holeB until it overflowsat hole P. Replaceplugs P andB. About 2~pints of oilare requiredto fill the buffer. -

II; To empty the buffer

- Securethegun to thecradleandtakeoff time front cradlecap. -

Withdrawtime bevel segmentfrom time piston rod, removethepin coupling theactuatingrod to the cut.off lever, aridturn back time bevel segment. - -

Unscrewthestuffing box, depress the cradle, and run- timeoil off into suitable vessels. --

iii. To tightentho gland:— - -

-- Pull the spring ~lunger locking the glandsto the front.Insert a tommy through the hmolo in the cradle cap intoone of the holes in thegland andtighten time gland. - Care

71

should be taken not to tighten the packing mere than isnecessaryto preventleakage. - -

iv. To renew the packing in the buffer glandElevate the gun to a convenientposition, secureit to

thecradle,andremovetimepistonrod andram nuts. Removethe cradle cap and disconnectthe cut-off gear. -

Removethe spring plunger and unscrew the gland ringandgland. Insert a supplementarypacking. Replacetimeglandring andgland, andreassemble. - -

v. To renew the L rubber in the stuffing box

Elevate the gun to a convenient position, secureit tothecradleandremovethe pistonrod andramnuts. Removethecradlecapanddisconnecttime cut-off gear. Removetimespring plunger and unscrewthestuffing box togetherwiththe defectivepacking. Renewthe packing. Replacetimestuffing box and spring plunger, reassemble,andrefill thebuffer.

7. THE AIR PUMP.

Before starting work an externalexaminationshould bemadeto see that the pump is cleanandserviceable.

When assembling,care must be taken to see that allparts are clean and ivell lubricated. Working parts willrequirefurther lubricationduring pumping.

To obtain the bestresultsit is essentialto employ a fullstroke in working thepump, i.e., from stopto stop.

When charginga systemit is be-stto continuewithout~astop until the desi~edpressureis reached,changingthemenif fatigued. If a stopis unavoidable,note thepressureand

72

close valve C. Before continuing, pump the pressureinthepipe up to the pressurenotedbeforeopeningvalve C.

If thereis any falling off in theworking pressure,examinetime valves. If gritty, the valves and springs simould beremovedandcleaned. If necessary,valvesshouldbe higimtlygroundin andcoatedwitlm thin oil. If this doesnot improvetheefficiencyof thepump,thepistonshouldberemovedandtime rings examinedandtried in time cylinders. If thespringof theserings hasbeendestroyed,tlmey must be changed.

- The pump must be replacedin its box immediately afteruse.

The pump should beworkedafew strokesdaily to ensurethat the pa-ekingsarekept underpressure.

GENERAL INSTRUCTIONS.

Practical instruction in the equipmentshould be givento eachrecruit beforeally attempt is madeto instruct himin gundrill. In teachingthedutiesof eachmanat the guns,theinstructorshouldtry to impart the instructionby rea.son-ing ratherthan by a long explanationin words. By meansof questionshe should try to draw from the recruit thocorreetanswersas to the performanceof his duties,beingcareful to lead theman’smind-into thedesiredchannelofthought. Should this attempt fail, the instructor shouldgive a demonstration,- emphasizingthe points the recruithas not grasped. Such demonstrationsshould deal withthe work of each numberin thedetachment;andall menunderinstructionshould,in turn, carry out the work of eachparticularman. - - -

Insti-uctionin gun drill should begin as soon as theyareconversantwith all parts of the equipment,and canhandlein the bestand quickestmannereach of theworkingpartsof the gun. Oncethework of eachmanha&beenthoroughlymastered,it shouldnot takelong for therecruit to learntheactualdrill.

It is most important thata markeddistinction should bedrawn betweeninstruction anddrill.

During theformer the languageusedshould be as simpleas possible, and the meaningof all technical terms whicharenecessarymust be carefullyexplained. A conversationaltone should be adopted,andunderno circumstanceswhat.ever should anythingin the natureof long quotationsfromdrill booksbe allowed. The men should be permitted toassumean easy attitude, and their interestshould not beallowedto flag. Theyshouldbe encouragedto askquestions.

At drill, on the contrary, rigid discipline must be main-tained, ordersmust be clear anddecisive,and thedetach.nientsmadeto work steadily,smartly andrapidly. At thesame time the ‘ltlnost accuracy is essential, and anydeviationsfrom the methods laid down must at once bechocked, -

CHAPTER V.—OARE OF EQUIPMENT.1. CLEANING AND OILING.

Limber gunnersshould be intelligent andreliablemen.The slippersshould be kept clean and oiled, andmain-

tainedin good working order; all working surfacesshouldbe well lubricated,and kept free fronm paiut.

The boreshould be kept cleanandliglmtly greased. Afterfiring, it should be scrubbedout with causticsdaandhotwater(one pound to a gallon), using the piasababrush.Whendry it should belightly greasedwith mnineral jelly.

~o gritty substance,such as sandpaperor bath brick,shotmld be used for cleaning working surfaces.

All sparepartsshould be usedperiodicallyto ensurethattlmey arein working order.

2. THE -DIAL SIGHT AND CARRIEfl.i. The No. ‘7 dial sight.

The dial sight when issued is in correct adjustment,watertight,and with all time cells and joints securedwithfixing screws.

It is very unlikely that time interior will requirecleaning,andtime dial sight must on no accountbe taken to piecesexcept by a person in possessionof an Artillery Collegecertificatestatingthat he is competentto do so.

The body of thedial sight should be cleanedwith n cleansoft cloth and alittle oil, which must be rubbedoff after-wards, carebeing taken that the glass is not touched. Nogritty substnneoshould be used,

The exteriors of eye lens and window simouid he cleanedwith chamoisleatherspeciallykept for thepurpose. Greatcaremust be taken that no oil or greaseis allowedto touchthe glasses. Fingers, thougim apparently clean and dry,leave marks on the lens wimich will inmpair the definitionof time sight.

When not in use the dial sight should ho kept in timesight box.

ii. The No. 5 carrier. - -

If thesiglmt is loosein tho bracketit maybe dueto :—

(a) The clamping screw headworking out of its recessmakingit impossibleto clamp up. The remedyis to presstheheadinto therecessand clamp.

(b) Time bracketbeimmgworn or strained,owing to workingthesight aboutwhen taking it out of thebracketor over-straining time clampinglever. In this casea clamp to com-pressthe bracket should be fitted if available; if not, one

70

side of the bracket should be tappedlightly and evenlywith a hammer by an artificer, with-the clamping scm-ewloosened. - -

3. THE BREECH MECHANISM.

i. General precautions. -

The breecim mechanismshould be dIsmantledperiodicallyin orderthat it maybe thoroughlycleaned. --

The threads of the breech screw should be free fromburrs; thosemayberemovedby careful filing byanartificer,but no portion of the threadshould be cutawayto removea crack. -

Time breecim should be kept coveredup, when possible,to preventdustandgrit getting into thebreechfittings.

ii. To dismantle the breech mechanism :— - -

Before removing the mecimanism the breech must beopenedandthe breechntecimanismnswung into the loadingposition. . -

Care should be taken to see that thereare no burrs ordirt presentto give an incorrectprotrusion. -

4. THE JUNCTION NUT.

%~lmonassemblingthe glmn, care simould be taken to seethat

(i) Time parts of the junction are clean and time screwthreadsof thejacketandjunctionnutaregreased.

(ii) The featheron breechportion, fits into the slot inthemuzzleportion.

(iii) The two portions are brought togetherwithout ablow.

(lv) Theindieatimmgarrow on upperfront of junction nutcoincides with the indicating arrow and word“Enter” on the step ring, when placing thebreechandmuzzleportiommstogether.

(mc) The indicating arrow on time junction nut coincides‘with the arrow on the stopring, showinglimit ofwear,whem~themiut ~sscrowedhome,

73

Generalprecautions.The junction nut should be dismantled periodically, in

orderthat it may be thoroughly cleanedand oiled. Thethreadsof the junction nut andworm simould be free frombtmrrs.(I) To disntantlm thejunctionnut

Removetime slipper ring at the muzzle end of the elmaseportion.

- Removestop ring by taking out the two screws,mmnscremvthe ring and pass it over the muzzle. The securing screwsare not interchangeable. Turn junction nut to the dis.engagepositionandcarefullyslide it overtime muzzle.

Remove set screw of worm spindle and worm spindle;removewormn andball bearingfrom inside junctionnut.

Reversethe order as above. The arrows on worm amidworm spindle,should coincidewhenreplacingthelatter.

5. RECUPERATOR AND BUFFER.General precautions.

I. Before firingCaro should be taken to see that time recuperator and

buffer are correctly charged, that timere is no n-bnormnileakageat the stuffing boxes,that time nut sectmringimowitzeris correctly locked, that time piston rods arefirmly nuttedupto thefront cradlecap,arid that the cut-ofTgearis in adjust-

74

It is necessary to strain the oil before charging therecuperator or buffer.

During severe weather recuperators and buffers should beprotectedas much as possible fronm the cold.

Recuperator arid buffer cylinders slmould be wasimed outwith paraffin or hot water to remove grit as opportunitiesoffer.

Any operationsfor the replacementof worn or defectiveparts whicim necessitateemptying the recoil system shouldbe carriedout only underqualifiedsupervision.

ii. In action ;— -

iii. When guns are restingin actionCool time bore. Allow air to escapefrom the buffer.

Replenishmthebuffer.- Tightenpackingsif necessary. Testthe air pressureafter theegun lmas cooled.

6. THE RECUPERATOR.i. Generalprecautions;—

Before the front cradle cap is removed, the gun must.be secured to time cracllo so as to prevent it slipping back.

If time cradle cap is to he left off for alongtinme,time elevatinglianuiwheei should be takenoff.

ii. To chargetho recuperatorwith liquidSecuretime gun to time cradle. Db~chnrgeanypressurein

elicmommmeter. Removeplugs A andcap of nipple for adapter,amid fully openvalve 0.

Allow any excessliquid to overflow from hole of adapternipple. ReplaceplugsA andcapof mmipple and close valve C.

Careshould be taken to see that time recuperatoris cor-rectly charged;as too muclm oil will causeseriousdamageand put time gun out of action.iii. To charge the recuperatorwith air:—.

Before charging t-he recupei-ator with air it is importantto seethat time securingcollar is in the correct position onthereeuperatorrod, in orderto prevent time rod from beingforcedout to time rear,whenunderpressure.

77

Attach the air ptimp to the bracket on the right trail.Place the cradle at full depression. Remove cap fromadapternipple and attach time adapterand pressuregauge;connecttho pump pipe to the adapter. Open the by-passvalve C and pump until the gaugeregisters510 lbs. a sq. in.Close valve C, disconnect the pipe fromtheadapter,amidplacet-he cap on the adapter. Let the pressure down slowly to500 lbs. a sq. in. by opening valve C slightly and slackingback time cap on theadapter.

When thepressurereads500, close valve C, removetheadapterwith pressuregauge and replace cap on adapternipple.

When chargingby air bottle caremust be takento opentime cock graduallyto avoid damageto thegauge.iv. To test the air pressure ;—.

Place the cradle at full depression. -

Removecap from adapternipple andattachtho adapt-erandpressuregauge. Blank theouterend of time adapter witimthe cap. Open valve C and the gauge should register500lbs.a sq. in.

If the pressure is correct, close valve C, remove theadapterandgauge,andreplacecap of adapter nipple. If timepressureis not correct,closevalve0,connectup theairpump,and make up the pressure to 500 lbs. -

V. To replenish air pressurelost by leakage:—

Proceedas for charging the recupcratorwith air, but,beforeopeningvalve0 to admit air to the recuperator, pumpthepressurein the pipe up to 500 lbs. a sq. in.

If the air pressurefails below 375 lbs., discharge the airpressureand check the amount of liquid in the recuperatorby levelling time cradle, remmmoving plugs Aand cap from adapternipple, andopeningvalve C.

78

vi. To empty the recuperatorSecure the gun to the cradle, disconnect the piston

and recuperator rods, and remove the front cradle cap.Dischargethe air pressureby removing cap from adapternipple and opening valve C. Removethe securingcollar,recuporatorstuffing.box,throttle valve andspring,andrunofftime oil. Rocktime cradleup anddownto ensuretime completeemptyingof time reservoirandrccuperatorcylinder.

vii. To renew the packing in the recuperatorglandandthe L rubberin therecuperatorstuffing box:—Theseoperationsare similar to thosein Section 7 (iv)

and(v) below, exceptthat theair mustbe dischargedbeforeremovingthesecuringcollar from the rod.

7. THE BUFFER. - -

i. To fill the buffer

Placethecradleat full depression. -

Removethe filling hole plugs D and B at the rearendof thebuffercylinder, Pouroil into hmole B until it overflowsat hole P. ReplaceplugsP ‘and F. About 2~pints of oilarerequiredto fill the buffer.

ii. To empty the buffer :—

Securethegun to the cradleandtakeoff thefront cradlecap.

Withdraw the bevel segmentfrom the piston rod, removethe pin coupling theactuatingrod to the cut-off lever, andturn backthe bevelsegment.

Unscrewthestuffing box, depressthecradle,andrun timeoil off into suitablevessels.

79

iii, To tighten the gland:—

Pull the spring plunger locking theglands to the front,Insert a tommy through the hole iii the cradle cap intooneof the holesin time gland andtighten thegland. Careshould be taken not to tighten the packing more than isnecessaryto preventleakage.

iv. To renew the packing in the buffer glandElevate the gun to a convenient position, secure it to

thecradle,andremovethenutsof thepistonrods. Removethecradlecapanddisconnectthecut.off gear.

Removo the spring plungerand unscrewthegland ringand gland. Insert a supplementarypacking. Replacetheglandring andgland, andreassemble.

v. To renew the L rubber in the stuffing box :—

Elevate the gun to a convenient position, secureit tothecradleand removothe nutsof time piston rods. Removethecradlecapanddisconnectthe cut-off gear. Removethespring plunger andunscrewthestuffing box togetherwiththe defectivopacking. Renew the packing. Replace timestuffingbox and spring plunger,reassemble,and refill thebuffer.

8. THE AIR PUMP.

Before starting work an externalexaminationshould bemadeto seethat thepumpis cleanandserviceable.

When assembling,care must be taken to see that allparts are clean and well lubricated. Working parts willrequirefurtherlubrication duringpumping.

80

To obtain thebest resultsit is essentialto employ a fullstrokein working thepump,i.e., from stopto stop.

When charginga systemit is bestto continuewithout astop until thedesiredpressureis reached,changingthemenif fatigued. If a stopis unavoidable,note thepressureandclose valve C. Before continuing,pump the pressureinthe pipe up to the pressurenotedbeforeopeningvalve C.

If thereis anyfalling off in time workingpressure,examinetime valves. If gritty, the valves and springs should beremovedandcleaned. If necessary,valvessimould belightlygroundin andcoatedwith thin oil. If this doesnotinmprovetime efficiencyof thepump,thepistonshouldberemovedandthe rings examinedandtried in thecylinders. If the springof theserings hasbeendestroyed,they nmust be changed.

Time pump mustbe replacedin its box immediately afteruse.

The pumpshouldbeworkeda fewstrokesdaily to ensurethat thepackingsare keptunderpressure.
