3)~ec~cation of an improvement upon the ordinary Machinejbr Card- ing FFool. Patented byDoa" MAL~CUS BAco~Huntington, Penn. sylvania, Oct. 10, 1828.

MY.. improvement, upon. the.. machine for. cardin.g,' wool~ consists, in raising the mare cyhnder of the carding machine, about fourteen inches above the fi+ame, so that a larger portion of its surface may be made to act upon the small cylinders. In the ordinary machine~ there are three or tour workers~ and two strippers: b y my improve.. ment, I usually employ seven workers~ and three strippers. The seven workers ~ are operated upon by two separate bands or cm'ds, from the same whorl, on the dnit~w shaft. ~ y this arrangement, three or Ibm" of them may, at a W time, be stopped~ when it is in- tended to run the wool twice thvough~ or by running the whole number, the work may be completed at one operation. What l claim as my iuvention is the employmertt of the additional workers and strippers, l)ox M, B~(;oy.

~pecijicatio~ of a Tria~tgular Measure~ca,~,e Ruler, for detineatb~g garments with~ or by. Patented by Ai.LEX WAi'.D, Philadelphia, October t l , 18~8.

To make a triangular measure-case ruler~ foe delineating garments~ l first p,'oeure three strips of tin or other metal plates~ with which 1 fiH'm a triangular tube, baying the edges of the metal strips turned outside, forming a trough or gl:(mve of each strip. .[ next proceed to solder the three troughs, or grooves, together, which, of course, forms a triangular tube, with the troughs or grooves outwards. I next prepare each side of the triangle for receiving the scales which are to be used therein~ by regulating the depth of the at'oove or trough to the t.nckness of the scales, and by marking on eadi side of the trmn~ular tube, some pecuhar mark, such as ~s used m musm to denote tunes, flats, sharps~ &c. any character will do to know the scales apart by' I have used a sliarp to designate the scale of lengtlas, or [mights, of each customer~ and have marked the charac- ter on the side where the length scale belona's~ and on the second side, I have marked the character of a la, ova. ~ in oilier words, a hul.- low square, which denotes the waist scale; ~ lastlv~ 1 have marked the third side of the triangular tube with the character of a natural~ whicli denotes the breast scale; and into these three gr'ooves I slide

• each respective scale, according to the height and tMckness of each eustomero I also make some triangular measure-ease rulers {'ur de- lineating garment8 by~ of wood~ whicli answer t h e same purpose~

but are not so durable. To make a wooden triangular measuro~cgse ruler tbv delineating garments with, I take a piece ~of w0od~ ab0~:t two feet long and two inches square~ of which I form a triang~!~r ruler~ in each side of which I plough a dove-tail groove fot-(the scales to slide in. I then put a band of wood Or metal round each end, {by {he twofold or dot{ble purpose of holding the marks or cha-. vacters of each scale, and for a supporter of a wedge with which the sca~es must be secured, to keep them from sliding back and forth.

Of the 45 premiums ofl'ered by the Institute, £0 were claimed by one or more competitors, of which three remain under advise,nent, and 9 were awarded by the committee to success- ful competitors. Of" the remainder, several were withheld, because the condition of the proposal was not adhered to.
