SHUTTLE-LOCKING MEANS FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent N0. 787,832, dated April 18, 1905.

Application filed November 18. 1904. Serial No. 233,319.

To (1J7 whom, it nm concern:

Beit known that l, H ENnY COTE, a citizen of the United States, and a resident of \Vest \Varren, county of "orcestQr, State of Massachusetts, have invented an Improvement in Shuttle-Locking Means for Loomsof which the following description, in connection with theaccompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of novel means for automatically locking the shuttle in the shuttle-box of a loom to prevent rebound of the shuttle upon striking the picker and to more accurately position the shuttle for subsequent operations. If the shuttle rebounds, it is not started from the box at the next pick and may fail to reach the opposite box or to box properly, the picking becoming irregular and producing a bad effect on the cloth. If the loom is provided with automatic lilling-replen ishing mechanism, it is highly important for the proper operation of such mechanism that the shuttle shall be accurately positioned in the box, a condition which manifestly cannot be fulfilled if the shuttle rebounds.

The various novel features of my invention will be fully described in the subjoined specilication and particularly pointed out in the following claims.

Figure 1 is a top or plan view of a portion of a loom, showing a shuttle-box equipped with one embodiment of my invention and with the shuttle locked in the box. Fig. 2 is a detail in front elevation of a portion of the shuttle box, the front wall thereof being broken out to show the shuttle-locking means. Fig. 3 is a rear view of the locking means and the shuttle just before it is engaged thereby; and Fig. l is a plan view, partly broken out, of the outer end of the shuttle-box, showing the outgoing shuttle just as it has been released by the locking means.

The lay 1, longitudinally slotted at 2 for the reception of the pickerstick 3, having an attached pickerlr, the shuttle-box, comprising a front plate 5 and top or cover plate (5, and

shuttle S may be and are all of well-known construction.

In Fig. l l have shown a portion of the filling feeder or hopper F and transfcrrer f" of automatic filling-replenishingmechanism substantially of the type shown and described in United States Patent No. 529,940 to automatically insert a fresh filling-carrier into the running-shuttle, the latter being shown of the automatically self threading type. If the shuttle rebounds, it will not only fail to be picked properly, but in an automatic fillingreplenishing loom the incoming filling-carrier will not be inserted properly in the shuttle, and a breakage of the shuttle or some of the adjacent parts of the mechanism willbe almost certain to occur.

In accordance with my present invention I attach to the picker an eh'mgated spring finger or catch 9, extended toward the center of the loom and having at its extremity a lug or projection 10. Herein the catch is shown attached to the rear side of the picker by suitable screws 11, Fig. 3, and the projection l0 is on the front face of the catch, the latter being bent rearward, (see Fig. 4-.,) so that the shuttle-point can pass the projection and impinge against the face of the picker. The length of the catch is such that when the shuttle engages the pickcr the projection 10 will be directly opposite a recess a in the side of the shuttle, and in the present instance this reccss is the socket which receives the end of the screw which holds the threzuling-block in place. An upright elongated lug 12 is fixedly mounted on the lay just behind the shuttle-path and parallel thereto back of the spring-catch 9 and at such a point that the outward movement of the shuttle after impinging upon the picker will cause the catch to wipe over the lug and the latter will press the projection 10 into the recess x in the shuttle. This is shown in Fig. 1, the shuttle being positively connected with the picker, and thereby held from rebounding and at a definite position in the shuttle-box. \Vhen the picker is moved inward to throw the shuttle from the box, the catch maintains the connection between picker and shuttle until the catch is free to spring outward, having passed beyond the control of the lug 12, as shown in Fig. 4:. Just at the instant the springcatch is thus i'reed it withdraws the projection 10 from the recess in the shuttle and the latter is free to travel across the lay. The binder B is bent rearward at b to clear the lug 12, and a longitudinal recess 6 is made in the binder-face (see Fig. 4) to permit the catch 9 to operate, as has been described.

From the foregoing description it will be manifest that the shuttle is locked in the box by means controlled by the picker and that the shuttle is released from such locking means by or through the inward stroke of the picker. The lug l2 constitutes a controlling device to press the locking projection into cooperation with the shuttle and to retain the parts in cooperation until the picker and shuttle have moved inward to a predetermined point.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be varied or modified in different particulars by those skilled in the art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a loom, a lay havinga shuttle-box, a picker, and means movable therewith to automatically lock the shuttle in the box and prevent rebound.

2. In a loom, a lay having a shuttle-box, a picker, means movable therewith to automatically lock the shuttle in the box as it moves to the end of its stroke with the picker, and means to release the shuttle by or through the inward stroke of the picker.

3. A loom having in combination a lay provided with a shuttle-box, a picker, a locking member carried thereby, and means to effect positive engagement of the said member and the shuttle as the latter reaches the end of its stroke.

4:. A loom having in combination a lay provided with a shuttle-box, a picker, means to temporarily and positively connect the picker and the incoming shuttle to prevent its rebound, and a controlling device for said means.

5. A loom havingin combination a lay provided with a shuttle-box, a picker, a springcatch mounted thereon, a shuttle having a recess to be engaged by the catch, to eifect the connection of the shuttle with the picker, and a controller fixedly mounted on the lay, to press the catch into engagement with the shuttle as the latter reaches the end of its stroke, the catch releasing the shuttle when the inward stroke of the picker has carried the catch beyond the range of the controller.

6. In a loom, in combination, mechanism to automatically insert a fresh supply of filling in the shuttle, a picker, and automatic means movable therewith to automatically lock the shuttle in position to receive a fresh supply of filling, said means releasing the shuttle by or through the inward stroke of the picker.

7. In a loom, in combination, mechanism to automatically insert a fresh supply of filling in the shuttle. a picker, a yielding catch mounted thereon and having a projection at its inner end, a shuttle having a recess adapted to receive said projection when the shuttle is to be locked, and means on the lay to force the projection into the recess when the shuttle has reached a predetermined point in its movement, to thereby retain the shuttle in position for filling replenishment.

8. In a loom, a lay provided with ashuttlebox, a binder, a picker, and means movable therewith and operating independently of the binder to lock the shuttle from rebound and to automatically release it by or through the inward stroke of the picker.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. A

HENRY COTE.
