TTOHNE YS Fo all whom it may concern.

Be it known that I WILLIAM H. WILSON, citizen of the United States, and a lresident f New Bedford, in the county of Bristol nd `State of Massachusetts, have invented a iew and Improved Loom-Shuttle, of which he following is a full, clear, and exact decri tion.

iis invention relates to hand-threading oom shuttles and more articularly to the :onstruction of the threa -engaging and deivei'ing portions of the shuttle.

My invention is applicable to the ordinary ype of shuttle in which a bobbin is supported within an opening in the body of t e shuttle so as to deliver the thread oit the end of the bobbin and through a delivery eye in' the side-of the shuttle.

One im ortant feature of my invention involves. a p ate emplo 'ed for preventi loo s formed in the threa at the end of eac pic t, from swinging upwardly and out of the thread-receiving s ot in the shuttle.

A further important feature involves the f tensioning device through which the thread passes to the delivery eye.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of ref eronce indicate corresponding parts in all the figures, and in whichery end of a shuttle constructed in accordance with my invention; Fig. 2 is a side elevntioul thereof; Fig. 3 is a view similar to a `iortioii of Fi 1, the thread-retaining plate being remove Figs. 4 and 5 are transverse sections on the lines 4 4 and 5-5, respectively, of Fi 3; Figs. (l and 7 are transverse sections on t e lines 6-6 and 7-7, respectively, of Fi 6; and Fig. 8 is a top plan view of the t read-delivering and tensioning device detached from the shuttle.

Various different forms of shuttles may be constructed'in accordance with my invention and various different changes made in the details, without departing from the spirit of my invention. l

As illustrating one form which the invention may assume, I have shown in the accom anying drawinlgs, a shuttle 10,'having an e on ated centra openin l. adapted to receive;I he shuttle 1% and de iver the thread therefrom throu h a delive eye in the side of the shuttle. n'theitoplo the shuttle, adjacent the delivery en'd, there is a substanlpcotilcltlon of Letters Patent. animation and september 4, isos. suini No. 516,189.

tially vertical o enin 13, extending'down about half way t roug the shuttle and conuected to the elongated opening 11 by a throat 14. The upper end of the'opening`18 andthe sides ofthe throat may be beveled or clit away, so as to avoid the sharp edges which might cut or sever the thread.

Extending transversely throu h the shuttle is a substantially cy indrica assage 16 of somewhat less diameter than t 1e opening land communicating with the lower end of the latter. A slot 16 extends from the o enig 13 diafronally fprward to one side o the 'shuttle and extends downwardly in depth to approximately the. plane of the diameter of the transverse passage 15. A substantially horizontal slot 17 connects the lower or innermost portion of the slot 16 with the transverse passage 15 along approxima ily one-half the length of the latter.

In threading the shuttle, the thread is dropped through the throat 14, the opening 13 and the slot 16, to the slot 17, and then brought into the transverse passage 15, so that the thread extends out through one end of the latter. For preventing a loop in the thread from rising or ballooning out through rovide a thread-retaining member within t e opening 13, and so constructed as to facilitate the entrance of the thread but to prevent its return movement. Figure 1 is a top plan view of the delivg This thread-retaining means includes a. plate 18 mounted upon a pin 19 and constituting a head for the latter. The iii extends down into the body of the shutte and holds the plate in place although by a plying pressure to the un er side of the p ate, the plate and pin may be readily removed. .The plate has one ed e thereof curved to coincide with the side we 1s of the o enin 13, so that said plate can not rotate about tghe in as a oenter. Opposite this curved si e, the plate has a projection or beak 20, terminating closely ad'acent the side of the o ening13 but space therefrom a suicient distance to permit the passage of the thread. The beak is curved downwardly as indicated in Fig. 4 and extends laterally ast the o posits'ffin'de' of the throat 14, as n icated in 1. .The plate has one side .hereof substantiall -i'i alinement with the side of the slot 1 so that when the th d is brought down through the slot, tliiend in the thread will pass along the edge N the plate to the beak and sli lsst the la As the gea r to the under iside.` is out of a inement .with anyp'orf.

'Within the transverse assage 15 is mounted my im rovcd tensioning and guidin derice.` 'Thdevice is preferably n the orm l 15 of a tube or barrel 21 fitting closely within the'paesa andreinovable len hwise there- Afrom. e tube is formed m a single 'ece of sheet metal so cut and stamped as to orm not onlgathe body 22 of the tube, but also an end and two transverse bars 24 and 25. The end 23 is provided with a slot 26 therein and extending from the lower edge of the end past the center of the end, so that the`upper end ofthe slot constitutes the delivery eye of the shuttle. The entire lower portion of the tube adjacent the end 28 is cut away, so that adjacent this end the tube is only substantially semi-cylindrical in cross section. The bar 25 extends across 30 the tube and has both ends secured to the ed of the senii-cylindrical portion as is n,izricated particularly in Fig. 7. The bar i has a free end extending toward the point of the shuttle and spaced from the edge of the semi-c lindrical rtion, as is indicated particular y in Fig. The free end of the ar 24 fits into a recess in the. wall of the lehnt/tlc andhas its u per surface substantially in the plane o the lower surface of the slot 17, so that as the thread travels rearwardly through this slot, it will pass i on t0 the upper si e of the bar 24. The poi'- tionof the cylindrical passage 15, adjacent the end 23, iscut awa or en urged to form a curved assage 27 a ong the lower portion of the si e of the end 23 toward tbe oint of the shuttle and communicating wit the s1ot.26 in said end 23. Thus, the thread in passing rearwardly through the slot 17 will 'i0 pass beneath the bar 25 and over the bar 24 and thence around a portion of the ed of the end 28 to the lower end of the slo 26. The e'id 23 is spaced inwardly a slight distance from the outer surface of the shuttle so that vafter the thread has once asse through to the position indicated in i 5,

it cannot ass out of the lower end o the slot 26. e bar 24 holds the thread ad'acent the up r end of the slot and nearer t e 00 center of e end.

The tube upon its upper side and intermediate its ends has an opening 28 com- `niiinicatin with the aperture 13 in the body '1- ofthe shu tle, and from this opening a slot 05 29 leads. to the edge of the semieylindrical and-thence travels through the latter to la es mounted on `two separate pins and ing 28 from the end opposite to the and Aslot 29. rI'hc tube at t e en ,oppesite te end 23, has the edges of the sheet m gortion and to the lower end of the slot' hus the thread in passing down thr the slot 16, comes to the end of the si .opening 28. The slot leadsl into the en sozthat as the thread is drawn out this the delivery eye there is no tendency ier y thread to accidentall esca ethrongh il forming the tube s ace/d a art ,a short tance and provide with ependin prays, tions or teeth 30, adapted to enter t e ier-n wall of thc transverse passage 15 and hoiLI the tube against accidental dis laccment.'

In threading the shuttle, it is merely ne i essai to dro the thread through the slot and raw it ack through the slot 17. Tl thread automatically slips over the beak and passes through the slot 29 and beneath` Y the edge of the tensioning and iding de,p i vice 21. The thread slips beneatglil one edgfg" of the end 23, so that it passes between the* two substantially horizontal guiding inem y bers 24 and 25 and between the two substan-,gl1 tially vertical guidin members at oppositci` i sides of the slot 26. gThe shuttle cannot bco como Unthreaded and the thread cannot hripp' come accidentally displaced or fail to oper! A roperly. aving thus described my invention, l claim as new .and desire to secure by Letters Patent:

1. A loom shuttle having a spindle recess, im an aperture extending into the body of the` shutt e adiacent the end of thespindlc rccess, a'slotextending from said aperture for wa'idly and outwardly to the side oi the. shuttle, a transverse passafve leading from 1nsaid aperture to the side ofnthe body, a slot connecting said passage and the lower pon tion of said first-mentioned slot, and a icusion device within said passage and inclufi- I ing two transverse bars extending across. 11i the passage, one disposed above said first mentioned slot and the other disposed below the same.

2. A loomshuttle having a transverse pasA sage through the wall thereof und through 1i` which the thread' assesy and n tensioning dev'ice within sai passage and including two bars extendin. transversely across tbc passage, and a slot eading through the wall of the shuttle to said passage and termi iur natin above one of said bars and below thc other art 3. A loom shuttle having a transverse passage, a` slot communicating therewith, and a tensioning device within said passage and 1 ncludin a transverse bar also extending across t e passage and constituting a continuation o one side ofsaid slot and a sc.;- oncl transverse bar forming a continuation of the opposite side of said slot. i
