FLY-SHUTTLE ATTACHMENT FOR QARPET-LOOMS.

SPECIFICATION forming part of Letters IPatent No. 537,045, dated April 9, 1895.

Applicatio11 filed November 9, 1894. Serial No. 52 8 ,344. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM H. KYNETT, a citizen of the United States, residing at Battle Creek, in the county of Calhoun, State of Michigan, have invented a new and useful Fly-Shuttle Attachment for Carpet-Looms, of which the following is a specification.

This invention relates to that class of looms employing fly-shuttles which are thrown back and forth through the warp across the batten by picker-sticks at the ends of said batten.

The object of this invention is to give to the shuttle a quick, forcible and never failing momentum to carry it across the batten of the loom as nearly as possible in effect as though thrown by hand, by means of a pivoted lever, the free end of said lever being attached by flexible means to the pickersticks which strike against the ends of the shuttle to throw the same, said lever being 0perated by means attached to the batten and to the loom-frame to swing its free end in either lateral direction when the batten is swung forward and backward, all as more particularly described and claimed below.

In the drawings forminga part of this specification, Figure 1, is a perspective view of a loom with my improvements attached; Fig. 2, enlarged broken details from Fig. 1, in perspective; Fig. 3, a plan of adetail from Figs.

1, 2, and 4; Fig. 4, an enlarged plan of details from Fig. 2, illustrating the operation, and Fig. 5, an enlarged perspective of details from Fig. 2, separated showing their construc? tion.

Referring to the lettered parts and numerals of the drawings, A is a loom, and B the swinging batten carrying the reed O, for closing the weft as in ordinary constructions.

on each end of the batten B, is a binder D, to receive the shuttle E, as it is thrown back and forth across the batten. One of the walls of each binder D, yields outward against the resistance of the spring 2, Fig. 1. This wall is removed in Fig. 2, to show the shuttleE, and the upper end of the picker-stick F, against the end of the shuttle ready to throw it across the batten B, into the binder at the other end of the batten. Fig. 1, shows the shuttle E, in the clamp D, at said other end. The office of these binders is of course to retain the shuttle E, in place until forced out by the picker-sticks Fr These picker-sticks F, are pivoted at the lower end at H, to the side standards I, of the frame of the batten B, so as to swing laterally during the operation of throwing the shuttle E. The upper ends of the picker-sticks F, work in a slot J, in the ends of the batten B.

On the under side of the batten B, at the center is pivoted one end of a lever L, the other end of said lever projecting forward, and to which cords N, or their equivalents are attached. See Figs. 1, 2, and 5. These cords N, extend each way laterally, pass through slots 0, in the picker-sticks F, and are attached at P, to the free ends of springbars R, which bars are attached at the lower end to the picker-sticks E, Fig. 2. At S, is shown a wedge shaped adjustable block by the raising or loweringof which the tension of the spring-bars R is varied.

The pivoted end of the lever L, is enlarged and thickened up at the rear forming araised cam portion T, from the apex of which, said cam portion slopes downwardly, forwardly and each way laterally. This pivoted end of the lever L, is provided with upwardly extending projections U, one on each side, Figs. 2 and 5, for a purpose explained in the operation.

The lever L, is operated by a hooked bar W, Figs. 2, 3, and 4, said bar being provided with a spade like end X, and having a hook Z, on each side atthe junction of said spade like end and the bar. The end of this bar W, opposite to the spade like end is pivoted at e, to the front beam 0, of the loom-frame A, Figs. 1 and 2, to allow the hooked end to play 1atorally during the operation. This end of the bar W, rests loosely on the apex of the raised cam portion of the lever L, between the projections U, Figs. 2 and t.

To add to the strength of the pivotal support of the lever L, and for convenience of construction, I connect the projections U, by a barf, and pivot this bar, at m to a plate 21, on the under side of the batten B, Figs. 2 and 5. I also provide a support n, to which the end V, of the lever L, is pivoted at r. This support 01, is provided with projections 15, which pass up through holes in the ends of the plate '5, and are attached to the batten B, and thus these parts are held together and attached to the batten.

In the operation, referring to Figs. 1 and 2, the batten B, has just been swung rearwardly away from the operator after closing a thread of weft during its forward movement, which of course will be readily understood by weavers. During the rearward swing of the batten 13, the left hand hook Z, of the hookedhar W, caught onto the left hand projection U, of the lever L, and swung the free end of said lever to the right. This action pulled with a sudden movement on the left hand picker-stick R, by means of its connecting cord N, forcing said picker-stick against the end of the shuttle E, and causing it to h y across the batten to the other end. In Fig. 1, the sh uttl e E, is supposed to be just starting, and in Fig. 2, it has crossed'over into the clamp D, at the right hand end. The shock caused by the sudden swing of the lever L, is first received on the spring-bar R, and thus cushioned before exerting the force on the picker-stick F, the cushioned force serving to bring the picker-stick firmly against the end of the shuttle E, before said shuttle is thrown by the tnrther movement-'of thepicken Continuing the operation, the batten is now swung forward to close the thread of stick.

Weft just carried through the Warp by the shuttle, and so on, the shuttle hei-ng thrown across the batten back and forth at e'ach rea rward swing.

No warp and wet t are here shown, but the supply of the weft from the shuttle and c'losing it in the warp by the forward swing of thebatten will be readily understood by those skilled in the art.

Referring to Fig. 4, to f u-rl-her explain the operation,-the lever L, and the hooked bar N, are in the position they occupy when having just operated on the right hand picker-stick. Now when the batten is swung forward toward the operator the spade like end V, of the ha r \V, will slide over the apex of the-raised cam portion T, to theother side as shown by 'dottcd position in said Fig. 4, and its left hand hook Z, will catch the left h and projection II, when the batten is again swung to the rearward. The dotted position shows the hook just caught as when the batten has started to swing back. This makes a positive, never failing movemenhand gives that peculiar and proper momentum to the shuttle E,necessa*ry to carry it across the batten, as explained.

Having thus described my inventiomw hat I claim as new, and desiretosecure by Letters Patent of the United States, is

1. In a lly shuttle attachment,the combination, of a batten, a picker-stick at each end of said batten, a lever provided with the raised cam portion and pivoted centrally to said batten, and provided with upward projections at the sides, means connecting the free end of said lever to the picker-sticks, and a bar having a hook at each side of one end, said end being adapted to slide over the apex of said cam portion of thelevcr. the other end of said bar being pivoted to a fixed support, substantially as set forth.

2. Ina fly shuttle attachment, the combination, of a batten, a picker-stick at each end of said batten, a lever provided with the raised cam portion and pivoted centrally to said batten, and provided with upward projections at the sides, means *connecting the free end of said lever -to the picker-sticks, and a bar having a spade like end with hooks at the junction 'of said end and bar, the other end of' said bar being pivoted toa fixed support, substantially as set forth.
