To all who/mit may concern: y y

Be it known that I, Vautrin Lnyiionn, a citizen of the United States, residing,r at Fall. River, in the county of` Bristol and State` of Massachusetts, have invented a new and use- 'i'ul Improvement on Cotton-Loom Shuttles,

of Which the following is a specification.

i My inventionf relates to shuttles and has for its ohjeet to improve the so-called handthreading shuttles in use on cotton and other looms. y i

Many Weaving mills still use a shuttle provided with an inclosed, curved passage through which the Weaver sucks the new tilling. rlfhis shuttle is strong, light, well haianced, impossible `to `unthread while the thread remains intact, and is inexpensive.

"its disadvantages are: the time consumed in` threading and the injury to the health` ot the operative due to the lint drawn into the lungs.

@ne type ot hand threading shuttle is provided with a heavy mass ot metal formed to guide and to y assume control ot" the thread. This type of shuttle is structurally weak owing to Athe amount o Wood which` must he removed to receive the threading device, 'and is also heavy, unlialanced, liable to unthread, and expensive; Another type of haiid-threading shuttle `is rovided with narrow .y slits in the top andJ side ot' the shuttle, with separate devices, usually ot' metal or porcelain, at. the entrance `and dei livery eyes. "These last named devices are .generally fastened in place by rivets or the lilrfr. lShuttles of `this"`type are unsatisfactory,-owing to the location of the slits nhich vare often ditlicult to make,- so placed that they weaken the shuttle, and frequently so formed that they leave projections on the 'shuttle `l`tocatch the Vwarps. They likewise `until-read Jveiy easily, and it has been found t'hfit the :rivets jar outas the shuttle becomes dry with age, thus allowing the guiding' de vices to tall out and injure the loom and the fabric. rlthese eyes. are also heavy and expensive.

In my improved shuttle, I have tried to combine the advantages oi a hand-threading shuttle with those inherent in the closedpassage type. The slits in my shuttle have been placed to facilitate quick threading, to

avoid wealteiiing; the shuttle body, to avoid all 'projections which might catch the ivarps,

and so that they may be made easily and quickly. The entrance and delivery eyes are tirovlildedfivith devices which` `are simple,`

light,""`inexpensive, and self fastening, requiringino rivets o1" other holding means, and vvhicliyadyust themselves to moisture `clmnfcg'es in the' shuttle Wood. The thread is `also positively trapped when once inserted and cannot unthread.

An important feature of any shuttle is the 'entirearrangement oparts in such a Way as to `prevent the unthreading of the shuttle due t'o kinks formed in any way, but particularly to those formed bytheunivmzling;` ot the hohbin and hy the natural twists of the thread itself. y 4 y 'the details of my invention are explained in theollowing description, aihd an attempt has hecnjniade to point out in the claim the notel features above enumerated.

lt ,will he understood that ,wlnle the claim lis intended to read on `the specitc form sliontn hy the diaiviiig, and cna shuttleo the species described, l desire 1t to include thosefohifious modifications within the doctrine oi equivalentswhich, While somewhat,

dilferentiroln my specific. device, will read-` Yily occur to those interested in this art, `and which will allour my, device to be used" on thread carriers of allllcinds and types.` l Figure `l is a perspective view ot a shut tie showing at. one end my iimpi'ovtments.I iiig. i. is :i longitudinal section of said. end

Fig. (i, is a horizontal section ot said end, Vtaken on the line vtf-1i, 'liigg-l, looking inthe direction of the arrow. Fig. 5, is a loi'igitudinal detail section taken on the line w, Fig. l, looking toward the longitudii'ial center of the shut tie. Fig. (l, is a perspective detached view oi the spiral spring 'forming either the entrance or the delivery eye.

The shuttle disclosed is of ordinary construction, eomposed of a body l., with a hohhinopening 2, which is adapted to receive an ordinaryhobbin A longitudinal slit (t leads from the hob hin chamber 3 toward thetip of thelshtittle. iilateral diagonal slit ti leads directly from the end of vsaid slit 4t to the delivery eye. The thread passage has hut one turn, therefore, which makes it easy to construct, and it will he noted that the shuttle is but little weakened. The junction oie the slits rounded as at (l, Fig. 4:, to prevent undue wear of the thread, and a slight depression y 7', Fi 1 vis formedlat the top of this junction in which to placev the finger duringthe threading operation, Y. and also to obviate Janyasha'v rp point, orJvp'rojectionl at this place t'ojcatch'.fthefyvrps vThe diagonal slit 5 is slantedjsinne"what sharply from the top to Athej bottom in the direction toward the obbin'i'chamber as shown-in Fi 5.,.

osed in the drawing, vthe l`spiral Qnfxrl'ailce eye iis turned to .thefright x'inte'rdetjlto beusedwith a bobbin ung'-in the opposite direction.

be evident that the entrance eye 9 and the slant of the slit 5 will prevent the thread from comin to the top of the shuttle. v The slant of sairgLslit acts as an overhanging point to always retain the thread in place. 5o It will also be noticed by viewing F1 3 that the distance between lthe inner en of the spiral Aand the outer body of the spiral constantly grows less as it approaches the extreme inner end. This is deslgned to trap the thread positively. The spiral is so bent and adjusted that the thread must, force this inner end back slightly so that once within the center of the spiral the thread is positively trapped. This feature can be readily adjusted to accommodate the nature of the filling used. The delivery eye is used in the sameway, but it will beunderstood that this positive trapping feature by the resiliency ,l of the spiral may or may not be used as is deelne best. f l
