arrangement and con struction of shuttle-holders., which are made to move at the same time through the warp from opposite sides, meeting at'or near the center' of the warp, where `the shuttle,-which has through the one-half of the warp been carried by one holder is taken hold of by the other holder and carried through the other halt` of said warp by this other shuttle-holder durngits- `receding motion.j i

In the accompanying drawings, Figure I l'represents afront view of my improved shuttle 4arrangement on a loom constructed to weave two pieces oi' fabric at onetime. The other figures represent detail parts and will be hereinafter referred to.

Similar iigures represent similar parts.

In the accompanying drawings, A A are the two side standards. Bis the breastbeam. In this breast-beam two sliding bars, G C', (shown in dotted lines,) are arranged,capable of sliding past each other, to which strong cards a a'- .are attached, running over suitable guide-rollers, ff, and connected with 'an arm or lever, generally called the peg-arm, in the usual manner, to give the required motionlto said bars. Near the other ends 'of said bars C C. cords a: x are attached, the lower ends of which are connected to springs lW W to bring the said bars C C back again to their original position as soon as relieved by the ac tion of the cords a a. To these barsC C the shuttle-holders D D and D D are attached. Theseshuttle-holders are made of a lower arm, n, firmly attached `to the sliding To this arm n an upper arm,"m, is hinged similar to shears or scissors. The forward part ot' the fixed arm n and movable arm m, forming the shears, are shaped so as to receive the shuttle between them. (See Figs. I and III.) The after V end of the arm mv is bent slightly upward and has a springe, attached, acting against the after part ot' the fixed lower arm, n, so as to press the forward ends of said arms a and m together to keep the shuttle E iirmiy between them. At the back of the breast-beam B levers G G G G are xed, provided with suitable projections at their upper ends, (see Figs. I and IV,) which, at the proper time, are made to act upon the ends of the arms m, so as to counteract the spring o, and, at the same time, open the shears to liberate their hold uponthe shuttle, as will be hereinai'terdescribed.

By operating the cords a c' the bars C C 'and consequently the shuttle-holders D and 'D' will move toward each other;

sented in the drawings, the shuttle-holders D have hold of the shuttle E, and will consequently bring said shuttles, by the above described motion, into the warp between the warp-yarns. At the same time the shuttle- `holders. D will enter the warp between the warp-yarns from thel opposite direction, and

meeting the former, which'has hold of the shuttle near or at the center of the warp, and cause the shuttle to enter likewise between the arms n m of the shuttle-holder D At the same time the levers G G are moved so that their projections shall act upon the after end of bent arm m of the shuttleholders D, relieving thereby the pressure of the forward end of the said arm m upon the shuttle E, while the arm m of the shuttle-holder D is acted upon by its spring O, so as to press the arms n and m tightly together to hold the shuttle E rmly between them. Thehpressure or power on the vcords a a is then taken off, when the bars C C will be forced back again by the action of the springs W `W" acting Ythrough the cords a: fr upon said bars C G,

and consequently the shuttle-holders'D D andl D D will be moved out of the warp again, and, as above described, the lever G'has acted and is still acting upon-the end of the arm m ot' the shuttle-holder D, so as to relieve the shuttle E of the pressure of said arm, whereby said shuttle E was held irinlyin said shuttleholderD, and as this shuttle E has been forced between the arms a and m f the shuttle- As reprey holder D, in which the arm m isacted upon by its spring O, so as to hold thereby the shuttle E rmly between the arms n and m of said shuttle-holder D', said shuttle-holder D' will, by the above-mentioned return-motion of the bars U C', carry the shuttle E past the second half of the warp and out of the same. The next motion communicated to the bars C C' will cause the shuttle E to be taken be'- tween the warp-yarns, fast -to the shuttleliolder D', until the same is niet in the-center under side of the breast-beam B, provided with suitable slots, R it Et' R', Ainto which the lower ends of the levers G G G' G.' work, and through which said levers are operated, so as to be brought -clear of the projecting part of the `arms m or the shuttle-holders, or to act upon the same in the manner and for the pur pose and at the required time, as above speciv:hed. 'This sliding bar H- is provided with two hook-levers, N N', acted upon by springs r r', respectively, fastened-to kthe .sliding bar H, and acting upon said hookdevers so as to press the same inward., s and s' are two springs fast to thebreast-beain B, but stronger than the springsr o", and acting against the hook-levers Nor N' in the opposite direction to the action oi' the springs 7' r', when said hooli-V levers are, in connection with the bar H, moved past said springs as'. p p' are arms fast to the shuttle-holder bars C C', projecting downward through the beam B and below-the slid ing har H and the hook-levers N or N', so as` to operate the said sliding har H.

In the position of the bar H, Fig. il, (shown in the drawings, and which corresponds to the position of the shuttle-holders, dac., asv

shown in Fig. l,) the hook-lever N is opposite the spring s, and acted upon by said spring, which being, as before mentioned, more powerfui than the spring-w, has moved said hooklever outward in such a position that by the motion of the bars C C' the arm p of the bar C will come into the hook at the end of the lever N, and thereby move the sliding bar H at the right time forward. The hooklever N', which in this position is away from the action of the spring s', is acted upon by' its spring r', and thereby pressed inward so as to allow the arm p' of the bar C' to pass the same during this motion., By'thismotion ofthe bar H, communicated to the same i'romthe connection ci' the arm p with the hook-lever N, the levers G G are made to pass from part 3 into part 2 in the slots R R, whereby the upper or projecting ends of said levers are thrown over the arms m of the shuttle-holders D, and act upon said arms in the manner and for the purpose abovo speciiied. G' G' are moved from part 2 into part 3 inV tl'e slots it' R', whereby Jthe upper ends ot saidl levers are brought clear of the shuttlehold` ers D, allowing thereby the full action of the spring o for the purpose oi1v forcing the arms n and m together to hold tight the shuttle E between them. .-During the return-motion of the bars C C', the. sliding bar H remains where the arm p has moved the'same, as above described, but the hook-lever N has thereby been moved away froinrthe spring S. in consequence of which the springr acts now upon said lever N and forces the same inward again, while the hook-lever N' is now in a position to be acted upon bythe spring S', and is by the same forced outward, sothat by the next motion ofthe bars C C',the arm -p' of the bar C' will catch into the hook at theend'oi:l the lever N', and move thereby this slidingbar H back again. By this back-5 motionof the bar H. The lower ends of the levers G' G' pass from part 3 to part 2 in the slots R', and throw thereby the upper end`s of said lever so as to operate the arms m of the shuttle-holders D', while thenlower ends of the levers 'G pass from part 2 to part 3 in the slots R, and move thereby their upper ends clear of the shuttle-holders D.

At the backside of the' shuttleholders a shield-plate, F, is attachech'sccurely fastened to the lower and Xed arm, a, of said shuttlef-I holders, and made sufficiently wide to project a little above and below the two -arms n and m, forming the' shuttle-holder.4 This shieldplate F is pointed at its forward end, wedgeshaped. This shield prevents any of the threads of the warp from coming into and between vthe arms n and m of the shuttle- 'holders, While the same passes between the warp-yarns empty, as this wedge-shaped end of said shield-plate F will either separate the yarns or cause the same to pass either above or below the shuttle-holder.

I do not claim, broadly, passing the shuttle vhy a shuttle-holder through one-half the distance of` the warp, where a second shuttleyholder takes hold of said shuttle and passes the samethrough the remainingother half of the warpduring its receding motion; but
