COTE, G1 \VOONSQCKET, RHODE ISLAND, A S- SIGNOR S, BY DIRECT All?) MESETE ASSIGNMEITTS, TO THE UNITED MILL SUEFLY, INC., A CORPORATION OF RHODE ISLAND CATCH-CORD Application filed April 5,

Our invention re ates to devices carried by loom temples ioi ensing with the use in weavi g of the can i cord or selvage cort formerly necessarily employed to retain the iilling, and sometimes styled catch cord eliminators.

The essential objects of our invention are to enab e the device to be employed either upon right hand or left hand temples; to enable adjustment of device longitudinally of the loom to acconnnodate cloth of various widths; to insure inv riable engagement of the needle with the shuttle-thread whereby missing any pick is avoided; to maintain the cloth at its natural width throughout the operation; to facilitate the application and removal of the device to and from thetemple; and to attain these ends in a simple, inexpensive and easily operable structure.

To the above ends primarily our invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification Figure 1 is a perspective view, from a point above and in front, of our eliminator applied to a loom-temple,

Figure 2. a fragmentary perspective of the base plate and bearing bloclr,

Like reference characters parts throughout the views.

Our device is herein shown supported by a loom-temple 10 of well known construction comprising the body 11 attachable to the top of a breast beam by the retaining plate 12, and a slide including the forwardly directed slidable arm portion 14 and the usual selvage retaining box portion. The latter consists of a base 16 and top 17, clamped together by a screw or bolt 19 whose shank, not shown, passes through an oblong longitudinally disposed slot 22 in an attaching or base plate 23 which is thereby fixed to the upper face of the indicate like ELIMINATOR 1929. Serial No, 352,879

the selvage retaining box, and, by virtue of the slot, is ad ustable longitudinally thereof. In this case a washer 24 1s interposed between the plate 23 and the head of the screw 19. Integral with an intermediate portion of the plate 23 is a lateral forwardlyprojeeting upwardly inclined lug or guide arm 26 provided near its free end with an eye 27.

Cast with the plate 23 or fixed thereto in any convenient manner transversely thereof is a bearing block 29 acent the arm 26 and parallel thereto. Journaled in a bearing opening 30 in the forward portion of the block is a rock shaft 32, In order to facilitate the complete removal of the rock shaft from the block if desired, the block is divided, as at 34, into a seat section 35 and a superposed detachable rectangular section 36. The bearing opening 30 is formed by registering semicircular bores 38 and 39 in the seat section 35 and in the lower face of the removable section 36. The latter section is secured by a screw 40 passing through a vertical hole 41 therein, and entering a threaded cavity 42 in the block seat section 35.

Integral with one end of the rock shaft 32 a forwardly directed lever arm 44, disposed at righ angles to the shaft, has a finger 47 integral with its end and right angularly disposed thereto, the arm and finger forming a crank. Integral with the other end of the shaft 32 is a forwardly directed downwardl inclined stop arm 49 disposed rectangularly with relation to the shaft, and at a radial angle of less than degrees to the arm 44. Integral with the forward end of the arm 49 is an upwardly directed contact lever 50 inclined at an acute angle to the latter.

A thread engaging member is in this instance bent up from a length of wire whose upper end is formed into a series of coils or a sleeve 53 "disposed at right angles to the remainder of the wire length which constitutes an integral pointed needle 54. The sleeve 53 is loose on the finger 47, and the needle 54 passes downwardly and loosely through the eye 27 of the lug 26.

The arm 49, whose outer end forms a stop, is normally pressed downwardly in contact with the front portion of the plate 23 by the following means. A horizontal rod 56 is frictionally or otherwise held in a transverse bore 57 in the rear portion of the block 29. A resilient length of wire is coiled helically upon the red 56 to form a spring sleeve 59, one of whose ends 60 is fir-:ed in a hole 61 in the outer end of the rod, while, at the other end of the coil, the wire is extended to form a spring arm 62 terminating in a loop 63 engaging and depressing the arm 49.

The operation of our device is as follows: As the loom lay in its vibration swings towards the beam, the lay, or an abutment carried thereby, will strike and rearwardly push the lever 50 to the position shown in broken lines in Figure 1, thereby raising the point of the needle 54 above the plane of the fabric being woven, since it is essential that the needle be out of the way while the thread laid in the shed by the shuttle is being beat up by the loom reed. hen, however, the loom lay returns to permit the shuttle to be thrown, and a new shed to be formed therefor, the needle 5% will have been downwardly impelled into the path of the shuttle thread 65 by the spring 59, thus retaining the thread against the pull of the shuttle as it progresses through the succeeding shed. Excessive descent of the needle is prevented by contact of the stop arm as with the plate 23.

It is to be understood that the invention is not limited to the specific form herein illustrated and described, but may be embodied in other forms without departure from its spirit as defined by the following claims.

o claim 1. In a device of the type set forth, a loom temple slide, a plate upon the slide, a rock shaft pivotally supported upon the plate, a forwardly directed crank upon the shaft, a downwardly directed needle upon the crank, a needle guide on said plate and an upwarely directed contact lever carried by the shaft.
