SELF-THREADING LO'OIiVI-SHU'TTLE.

srncirrcn'rron forming art of Letters Patent No. 559,306, dated April 28, 1896.

Application filed February 12, 1896. Serial No. 678,992. model.)

To all whom it may concern:

Be it known that I, PATRICK J. OGoNNELL,

of Hopedale, county of Worcester, State of Massachusetts, have invented an Imprvement in Self-Threading Loom-Shuttles,,of which the following description, incoiinec-J tion with the accompanying drawings, is a specification, like letters the construction of which is hereinafter more fully described and claimed.

Figure 1 shows a shuttle containing my improvements; Fig. 2, an enlarged top View of the delivery end of the shuttle;, Fig. 3, a like view of the end of the shuttle with the selfthreadingdevice removed. Fig. 4 shows an inner end view of ;-tiie*seif-'threading" device detached; Fig. .5, a side elevation thereof,

Fig. (i, an inner side view'of one half of the device; Fig. '2, an inner side view of the other half of the device; Fig. 8,'an outer or front end view of the self-threading device with the end of the finger cut on, and Fig-9.an under side View thereof.

The open shuttle-bodyA and the bobbin 1),

havinga cop c of thread, are and may be all as usual. The top side of the frontend of the shuttle-body is out out or chambered, as best shown. in Fig. 3, to leave a circular chamber a with a larger'eircular chamber b at its-upper end, a point-receiving chamber bleading from the ehamber a'toward the end of the body. .The' chamber a is intersected by two passages-b b the wall of the shuttle-body at the end of the passage b having a slot b,,which leads to the deliveryeye 0 thus making that eye open .for the (49'. i

HThe-selE-threading device is composedof.

reception of the'bobbin-thread.

two half-circular parts (1 6, having, respectively, faces d c, which abut together, a pin j d on the part d entering a hole 6 in part c and a pin (2 in part e entering a hole d -in part at the said pins supporting the bobbinthrea after the latter has entered theselfthreading device. The art d has a forwardly-e'xtended finger d recessed at its inner side to leavean overhanging flange d and a gliidaspace (1 and the top of part (Z on h rawin is provided with an annular semiflange d to enter the recess b The half e is-widened to form a flange c5 and has -a'forwardly-extended horn e provided with an inwardlyextended lip e which enters the space at the inner side. of the finger (1 below the flange d a slotbeing left between the flange of the fingerand the lip of the horn for the threadicaught under the point of the 110m draws under the horn and. is,by its down wardly-curved breasts and its outer inenne'aguidm edgavmece ,totravei' in the space f between the horn and the inner wall of the space 12" of theshuttle-body, and ar-;.

riving at the shoulder e' will enterthe open delivery-eye c. I

- The threadingdevice is held in the shuttle by a screw 'g, which enters the shuttle at its side rather than at its bottom, as heretofore,

and said screw, besides holding the device in theshuttle, also acts to hold together the two parts d 'e of the device. Where the screw for holding the threading device is inserted through the-bottomj-of the shuttle, it will be obvious that the shuttle is weakened in the direction of its length and in the line of the open chamber receiving the bobbin or fillingcarrier, and therefore the tendency of the shuttle to split lengthwise is greatly increased; but by inserting-the screw through the side of the shuttle the splitting of. the

shuttle is also obviated. By making each partd and e separately they may be cast in a mold, thus obviating cutting-slots and mil 1-. ing operations, which are very expensive.

I-Iaving .described my'invention, what I claim as new, and desire to secure by Letters Patent, is g A 1; A shuttle-body having a receiving-chamwall an open delivery-eye communicating with said chamber, combined with a'selfthreading device composed of two separate,

her at its upper side and having in its side detachable parts, one of said parts being made as a finger having its inner side recessed longitudinally to leave an overhanging flange 61 the other part, designated as a horn,. having a pointed lip to enter the recess below'the said flange, a downwardly-inclined breast e and outer inclined guiding edge, the said guiding edge forming one side of the thread-guiding slot through which the thread travels into the open delivery eye, substantially as described.

2. A shuttle-body having a receiving-chamber at its upper side and having in its side wall an open delivery eye communicating with said chamber, combined with a selfthreading device composed of two separate, detachable parts, one of said parts being made as a finger having its inner side recessed longitudinally to leave an overhan ing flange. d, the other part, designated as a horn, having a pointed lip to enter the recess below the said flange, and a screw passing through the side of the shuttle-body and entering and holding together the said separate detachable parts, substantially as described.

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