JOHN VILLIAM BARLOV, OF LAWRENCE, MASSACHUSETTS.

LOOM-PICKER.

SPECIFICATION forming part of Letters Patent No. 398,570, dated February 26, 1889.

Application filed November '7, 1888. Serial No. 90,190- (N0 odel) To aZZ whom, it may concern.-

Be it known that I, JOHN lYILLL-ui BAR- LOW, of Lawrence, in the county of Essex. and State of Massachusetts, have invented a new and useful Improvement in Loom Pickers, of

which the following, taken in connection with respectively an elevation and an inverted the accompanying drawings, is a specification.

My invention relates toloom-pickers, andhas for its object the production ofa picker which shallbe more durable than those heretofore in use, particularly in regard to the foot or tenon, which in the pickers now in use is made up of a series of layers of rawhide not tied together below the shoulders of said foot, and which layers are constantly being broken one by onetill they are allgone,which often happens before the picker has become otherwise badly worn, thus rendering the ,picker useless lon gbet'ore it should become so.

My invention consists in certain novel features of construction and arrangement of parts, particularly in connection with the formation of the foot or tenon, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given, and in which my invention is clearly pointed out.

Figure 1 of the drawings is a side elevation of a picker embodying my invention. Fig. 2 is an elevation of the opposite side of the same. Fig. 3 is an edge view of the same. Fig. i is an inverted plan of the same, and illustrates how the parts which form the foot or tenon are interlocked. Fig. 5 is an edge view of another form of picker, in which the body of the picker is made of uniform thickness from its top to the shoulders of the foot. Fig. 6 is plan of the blank of rawhide from which my improved picker is made. Figs. 7 and S are respectively a plan and an end view of said blank after being folded upon itself in the first operation toward forming the picker from the single piece of rawhide shown in Fig. 6. Figs. 9 and 10 are respectively a side elevation and an end view of the same, illustrating the appearance of the same material after the second folding or bending operation and the parts folded upon each other have been riveted or otherwise secured toof picker to be made.

gether. Fig. ll is an elevation of the same as viewed at right angles to Fig. 9. Fig. 12 is an inverted plan of the same material after the bow or eye has been opened out and the same has been subjected to the first molding or shaping pressure, and Figs. 13 and it are plan of a picker such as is now in common use.

In the manufacture of pickers such as are most commonly in use today a rectangular piece of rawhide is folded upon itself twice,

F so as to form a bar of rawhide, say, one and one-eighth inch wide by onehalf inch thick and ten inches in length, these dimensions being variable, of course, according to the size This bar is then bent at the middle of its length, to told one half over upon the other half, and the two parts riveted together. The eye or bow is then opened out and the whole is subjected to pressure in a suitable mold or die to compact and set it, it being understood that previous to any of the forming operationsthe hide has been softened in the well-known and usual manner. The foot or tenon is thenformcd by cutting away a portion of the stock upon opposite sides of the pendent or shank portion of the picker, the result of which is that the foot or tenon when completed is com posed of a series of layers of rawhide, the side ties formed by the folding of the blank into the bar form being all cut away by the cuts made in forming the foot or tenon, all as shown in Figs. 13 and it. This structure of the foot or tenon is objectionable because of the liability of said layers to be broken away one after the other until the foot entirely disappears and there is nothing to guide the picker and hold it; in its proper vertical posit-ion. To overcome this objection is the object of my invention, and to this end I form the blank A as shown in Fig. 6that is, I cut from two diagonally-opposite corners of a rectangular piece of raw hide, as at B B, Fig. 6, pieces of said hide of equal width and length, the width being about one-fifth (more or less) of the width of the blank and the length being somewhat in excess of the desired length of the foot or tenon to be formed upon the picker, and from the other two corners, as at G O, I cut pieces of the same length, but of less width than the cuts B 13.

The cuts in the direction of the length of the blank at the corners C C may be oblique to the edge of the blank, as shown in full lines at a a, or they may be parallel to said edges, as indicated by dotted lines a Z). (See Fig. 6.)

\Vhen the blank has been properly prepared, as above described, it is folded upon itself on the dotted lines g, h, and i in succession, to produce the bar shown in Fig. 7, a portion of the stock at the sides of the cuts B B being turned inward, as shown at c c in Figs. 7 and 8, and the stock at the sides of the cuts 0 C (indicated by the letters a or 1)) being bent, as shown at d d in Figs. 7 and 8. The bar shown in Fig. 7 is then bent at the middle of its length till one half thereof rests upon or is in contact with the other half, as shown in Figs. 9, 10, and 11, when said parts are firmly secured together by the metal staple or rivctsf, the flaps d (1' being first made to interlock, as shown in Fig. 10. That por- 'tion of the bent bar between its bend and the staple'or rivets f is then opened out and the whole is subjected to the first pressure indies to partially shape the picker, when the picker as viewed from its under side will appear as shown in Fig. 12. The second and final pressing operation condenses and compacts the foot to the size and appearance shown in Fig. 4-. The hole 9 is then drilled and the picker is ready for use.

It will be observed that the foot or tenon is formed entirely-by pressure, no stock being cut away. after the operation of forming the picker from the blank- A commences for the purpose ofreducingthe. foot or tenon to. the;

desired thickness, and that the foot or tenon is composed of only two parts, that are firmly interlocked and have their greatest width in thedirection which the picker moves when in operation, and in which the blow of the shuttle is received thereby. By this construction the strength and durability of the foot or tenon are greatly increased, and as a consequence the useful life of the picker is very considerably prolonged.

In the finished article shown in Figs. 1, 2, 3, at, and 5, D is the bow or eye, E is the shank or pendent arm, and F is the foot or tenon.

The depression or reduction in thickness of the shank or pendent port-ion of the picker illustrated in Figs. 1 and 3, which distinguishes it from that shown in Fig. 5, is produced entirely by pressure, the die for shaping it being made of the desired shape to produce the form shown.

WVhat I claim as new, and desire to secure by Letters Patent of the United States, is-

I l. A loom-picker having a foot or tenon composed of two parts, each folded upon itself and interlocked with the other.

2. A loom-picker having a foot or tenon composed of two parts, each folded upon itself and interlocked with the other, and having its greatest width in the direction of the movement of said picker when in operation.

In testimony whereof I have signed myname to this specification, in the presence of two subscribing witnesses, on this 3d day of November, A. D. 1888.
