T a/ZZ whom, it r11/ag., con/cern; I

Be it known that I, EVERETT S. WOoD,a citi- I zen of the United States, residing at Hopedale,

county of Worcester, and State of Massachu- Setts, have invented an Improvement in Loop- Controlling Devices and Yarn-Guides for Filling-Replenishing Looms, of ,which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates moreparticularly to automatic looms wherein the running shuttle, provided with an automatic self-threading de vice, is replenished with filling fromtime to time, a loom of this type forming the subjectmatter of United States Patent No. 529,940

and others of later dates. f In such looms theb reserve supply of filling-carriers or bobbins is held in a filling-feeder, the latter being moved intermittingly-tobring the filling-carriers one by one Ainto position to be transferred by suitablemeans` from the feederto the running shuttle, transfer being effected automatically while the shuttle is in the adjacent shuttle-box. The filling ends arefsuitably held at-the outer end of the feeder, and after receiving a freshv filling-carrier the shuttle is picked or shot across the lay to the opposite shuttle-box, the held filling end causing the filling to draw OH fromA the lilling-carrier and enter a longitudinal threadpassage in the threading ndevice of the shuttle. Supposingy that the filling enters such passage and b eneatha suitable retainingprong or other device, on the return sliot of' the shuttle thethread is f or should ybe drawn beneath a horn, and thereby. guided through -an open passage Ainto the side-delivery eye of shuttle enters with the threading device at its vleading end, and when the slack thread is .thrown forward it may un'thread the shuttle,-

or Vthe bight of the loop may catch on the prong or some other part of the threading device or even around the shuttle point and break as soon as tension is put upon `the thread when the shuttle is next thrown from the box.

Ineitherv case filling replenishment'or stop-- page of the loom iS required.

vvShuttle-threading devices have been provided with means to prevent unthreading, and

they have also been variously constructed'to prevent the catching of the loop when one is' formed and' thrown forward, such shuttlethreading devices being either of the automatic type for use in automatic filling-replenishing .looms orof the type where the threading is effected by hand', but into a delivery-eye having an open entrance. The most effective of such devices have very largely eliminated unthreading; but when the filling is slack it.`

'will frequently be thrown forward when the shuttle is boxed, catching on some part of the shuttle, and the thread will be broken.

My present invention-has for one of its objects the productionof extremely simple but effective means for'preve'nting Such slack filling if thrown forward from being caught in the threading devicev of 4or on the shuttle itself, 'such means being'independent of the shuttle, so that the latter may be equipped iwith any desired or suitablelthreading device proper entrance of the lling into the threadpassage ofthe threading device on the shuttle is greatly facilitatedand made more sure.

4either automatic or of the other type Specithreading after filling replenishment.

The various novel features of my invention as embodied in one practical form thereof will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a top or plan view of the replenishing side of aloomprovided with automatic iilling-replenishing mechanism of the type referred to with one embodiment of my present invention applied thereto, the fillingfeeder being shown in part by dotted lines and the lay being represented as on its backward stroke just before the replenished shuttle is shot from the shuttle-box. Fig. 2 is a right-hand side elevation of the parts shown in Fig. 1, the filling-feeder, however, being shown in transverse section on the line 2 2, Fig. l. Fig. 3 is a view similar to Fig. 1, but showing the lay farther back and the shuttle well along in its Hight to show more clearlyr the operation of the means for facilitating Fig. 4 is a front elevation of the right-hand shuttle-box, showing the operation of the means' for preventing slack filling' from being thrown forward onto the shuttle; and Fig. 5 is a detail in plan, showing how the loop if formed is held from being thrown forward onto the shuttle.

The' lay A3, having thereon a shuttle-box B, the breast-beam A40, to which is rigidly secured the stand A7 for the filling-feeder, comprising, essentially, plates or disks a a', connected by a sleeve a3, rotatably mounted on a horizontal stud a6, secured to the stand, the transferrer f', mounted to rock on the stud f, the filling-carriers '2), arranged circularly in the feeder and supported by the disks a a', and the filling-end holder b2 (shown indotted lines, Fig. l) may be and are allsubsta-ntially as in United States Patent No. 529,940

and operating as thereinl provided, the means for intermittingly effecting feed movementof said filling-feeder being all substantially as in United States Patent No. 664,790.

rlhe'shuttle S is provided with an automat-i ically self-threadingadevice T, having a longitudinal thread-passage t and a prong t eX- tended across the front end thereof, the filling in the operation of threading being drawn down into the passage t and beneath the prong t' as the shuttle is shot away from the replenishing side of the loom, and on the return shot the thread is drawn down into the usual side delivery-eye tx of the shuttle, Fig. 4, in well-known manner to those skilled in the art.

In the present embodiment of my invention I secure to the feeder-stand a guard which is so located as to project just above the eye end of the shuttle when the shuttle has entered and been stopped in the shuttle-box at the replenishing side of the loom, the position of the guard at such time causing it to engage a loop, if formed, and prevent it from being thrown forward onto the shuttle-point or the threading device. The guard is herein shown as a U-shaped bar l, (see Figs. 1, 3, and 5,) having a long shank 2 extending from one side thereof tothe feeder-stand, the outer opposite side of the guard being elongated toward the'front of the loom, as at 3,'and having a series of rearwardly-turned .teeth 4 on its lower edge (see Fig. 2) for a purpose. to be described. The guard is substantially horizontal, as shown in Figs. 2 and 4, and the shank 2 extends at right angles to the feederstand, said guard being located as near as possibleto the top of the shuttle-box B without hitting it as the lay beats up. At its forward end the extension 3 of the guide is beveled or rounded off to a point, as at 5, Fig. 2. rlhe shank can be secured to the stand in any suitable manner, and herein I have shown it as forming a prolongation of the pivot-stud 300, on which is pivotally mounted the yielding or cushioned buffer m, Fig. 2, constructed and operating as set forth in Patent No. 664,790, above referred to. When the shuttle is about to be picked from the box B on the backward stroke of the lay, the parts are in the relative position shown in Fig. 1, and the various parts assume this same position when the shuttle has just been thrown into said shuttle-box and stopped, except that then the lay is moving forward. If then we suppose the shuttle to have just been stopped, viewing Figs. 1, 4, and 5, shoulda loop tm of filling be thrown forward olf the tip of the filling-carrier such loop will hit the inner side of the guard 1 and will drop back and down either into the opening in the shuttle-body or onto the guard and will be pulled down and off as the lay completes its forward movement. In either case it will be manifest that the bight of the loop cannot fall onto the threading device '.I` of the shuttle nor onto the point of the latter, the interposition of the guard absolutely preventing such action. For a similar reason the loop cannot unthread the shuttle, for such loop cannot be thrown forward beyond the inner side of the guard. When the lay is fully forward, the shuttle is beyond the guard; but the latter has by that time performed its office. If the loop should be extremely long, it would still be rendered harmless by the guard, for the latter would stop its forward throw, so that it could not catch on any part of the shuttle. rIhe guard also serves as a guide for the filling immediately after filling replenishment and facilitates the entrance of the filling into the thread-passage t as the shuttle is picked from the replenishing side of the loom.

Referring to Fig. l, it will be remembered that the endmost filling-carrier of the series is the one transferred tothe shuttle, such endmost filling-carrier prior to transfer occupying the position represented at 0X, Figs. 1 and 2, and its filling end 50 is led around the edges IOO IIO

of the disks' d and 7)1 to the central'stud b2, and, I

as shown by dotted lines inV Fig. 1, the fillingend is led' at an angle/tothe axis of the feeder in order to...give some slack when transfer is effected. 1t willbelunderstood that the vfill-jj ing does not drawzoff (from the filling-carrier just .inserted in the shuttle) in a1 linev parallel with the feeder-axis, -because the lay is mov-l ing back and the shuttle".l is traveling across the lay; sothat suchz-linewillf be diagonalv fromjthe y'edge ofthe disk-Wto thje shuttle.

Again; as the laymovesbaclr the transferrerv frisesfand'the feeder-- is advanced, so that lshuttle hasjust been finserte'dand that the lay hasy moved back t just about the `picling- "point,` the feeder having advanced the next filling-'carrier bx f-to the=position'shown: The filling end-53, extending from thefilling-carrierb around the diskb to stud b2, passes undenthe guard 1 and is engaged by the .teeth 1 onthe-lower `edge of its Vouter side and is thereby -held when the feeder advances vto the position shown .inFig. v1.' As thelay-re'cedes andthe shuttle-is picked theifilling then leads from thee point 54 on the guide, Figs. 1` and 3, rather-.than from. ,the point 52 on disk b', and hence its angularity with relation to the shuttle-path is very much reduced, and it is held .more approximately inline 'with the thread passage t, facilitating its entrance thereto. By beveling the end of the guard extension 3 the filling end easily passes thereunder as the lay moves back.`

It must be borne in mind that inthe explanationof the action of the guide the lay is referred to as going back and the shuttle as just about to -be pickedin Fig. l` while the loop-controlling office of., the guard is performed on the forwardy beatv of the lay just after the shuttle has been stopped in the box. The same illustration, however, serves to explain the action of both guard and guide when the shuttle is boxed, as there is no change in the relative position of the various parts, save that the feeder advances 'one step between transfer and the retrogradel movement of the lay into the positionshown. In Fig. 3, h owever, the shuttle is in;y its fiight and the lay is moving back, the angle'between the shuttlepath and the fresh filling end becoming smaller as the shuttle proceeds to the left.

My invention is not restricted to the pre-` 65 expressed in the appended claims.
