v Application filed September 17, 1917, Serial No. 191,673.

Be itlnio'wn'that I, ALoNzo E. Riioanns, a

"citizen of the United States, residing at 'Hopedale, county tion with the accompanying drawing, is a discharging filling carrierivith means catching and meta specification.like characters on the drawing representing like parts. 3 This in vention rel atestowcft replenishing iooins pre't'eri'ibly of the automatic type an its object is to providenicans for catching and thus retaining the trailing end of the a nandoned filling carriei-ai'terits discharge from 'the shuttle 'inthe operation of repleniFlllDfll'lij' sothat it will not be caught and carried by the shuttle or the fresh filling carrier into the cloth upon the succeeding pick.

This object isseeured in the present invention by providing the rhutefwhich guides the for hung the trailingfilling" end which means is preferably provided by serratiug'the upper edge of; the chute.

The invimiionnlso has for its object to i provide a chute capahle of yielding both forwardlv and rearwardly from its norn'ial posiiiou so that danger of breakage or a smash is *[ueveuied ii the fillingcarrieibe caught be tween. the. chute and a inovinn part of the loom dli'ruig its discharge.

lhese and other objects oi: the invention will appear iuoretullvfrom the:accompanyingr d'eshriptiol'iand d rantings and'will hepar- "ticularl v pointed out in the claims.

nan end elevation"partially in ct'ion of so much of an autoinatir w 'tt pleni'shi ig'iooiu of the Northrop type/as is no i yadisclosure of the Figure l' ].n-esentinventionwith a preferred form oi the a d im'enliim embodied therein;

"F11 is 1: front eleiation of the transfer end ielav shown i all 1g. 1 together With a per the chute.

The present invention is not concerned with the'particular construction or operation of the general features of the 100m to which it is applied. For convenience of illustration the invention is Shown in the preferred form. selected embodied in an automatic filling woven into the cloth -tion.

In this type of lo'oin the frame or loom side 1 supports at the transfer end oi the 100m a hopper stand 2 upon which is mounted a rotary hopper 3 carrying the suppl of fresh filling carriers a. The lay :3 carries at the transfer end the shuttle box 6, and the lay and Shuttle box are provided with a vertical opening '7 therethrough to permit the downward discharge of an abandoned filling carrier when the shuttle is boxed at the transfer end of the 100m.

A transferrer 8 is pivotally mounted on the hopper stand and provided with a dog which upon the call for filling replenishment is lifted into the path ol 'a hunter 10 carried by the lay thus causing the trans terror to force a fresh filling carrier, in this case a'bobbin, from the hopper into the shuttle and therelo discharge the almndoned or exhausted filling; carrier or bobbin in the shuttle down lhrougltthe opening 7.

The end ot' the filling extending from the abandoned filling carrier through the eye, of the shuttle is usually, in feeler looms, severed by suitable mechanism adjacent the nose of the shuttle and this severed end must be drawn bar]; through the eye of the shuttle and clear of the shuttle or it is liable to be caught by the shuttle or by the fresh filling carrier and dragged harh'into the shed and causing an iinper'i ec in this invention mechanism is provided to catch and retain this filliug'end as the filling carrier is (llStil'ltll'god from the shuttle and. prevent it from being dragged back into the shed by theshuttle or the ,fresh filling eartion otthophflier, the picker guidc, and

rier.

For this purpose thechutc which coinprises a guiding plaie' ll upper edge l2 the serrations preferably pointing away from the shed. hen thelay heats up this chute contacts at its upper edge with the rear wall of the ()DGHIHQ 7 and as transfer takes place the discharged bobbin forced out through the opening 7 slides down and is guided by the chute 11 into the usual receptacle placed beneath the hopper. As the lay starts on its return movement the trailing end of the filling is serrated at its.

is caught over the serrated edge 12 of the chute and is caught and retained thereby so that it cannot be.

carried back by the shuttle or the fresh filling carrier into the shed. a

The chute 11 is provided at its lower edge with journals l3 and 14 by which it is pivotall mounted on a stud 15 carried by a brac (et 16 secured to theloom side. A heli- .cal-s'pring 17 upon this stud is secured at one end to the journal 14 of the chute and at the other end to a collar 18 fastened to the stud 15 by the cotter pin l9. This spring acts to hold the chute yieldingly in its normal position or about the position illus-' trated in Fig. 1 while allowing it to yield and swing forwardly. As the lay beats up the edge of the chute contacts with the rear wall of the opening 7 and the chute yields forwardly keeping in contact with the said wall.

If the filling carrier in descending on the chute should be caught by a moving part of the loom such as the hunter 10 while the lay was moving rearwardly it might get wedged in against the chute 11 and break or injure the chute and this not infrequently happens. To prevent this the invention provides means for permitting the chute to yield rearwardly from its normal position. For this purpose the bracketl-B carries at the rear of the stud 15 a socket support 20 in which is mounted a plunger 21. A helical spring 22, of greater tension than the spring 17, contained in the socket of the support 20 abuts at its upper end the head of the plunger -21gand'at its lower eng the bottom of the socket thus servin yiel ingly to project the un er u we rdly. A pair of nuts 23 are ghre ded dh the lower end of the plunger 21 and serve to Q0 limit and adjust the upward projection of the'Tplunge'ln' The adjustment issuch that when the chute 11 is in its normal position it contactswith the plunger 21 and the nuts- 23 contact with the bottom of the supp0rt20. If new upon the retracted movement of the lay the discharging filling carrier be caughtor jammed against the chute the chute will yield rearwardly pressing the plunger 21 against the action of the spring 22 and thus preventing b. :akage of the parts. A suitable guard 24 may be provided to prevent endwise movement of the filling carrier as it passes down the chute and is herein shown as rigidly supported from the lay by the bracket 25.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a weft replenishing loom a lay provided with a shuttle box and having an opening therethrough to permit the discharge of the abandoned filling carrier, a chute. located beneath said opening to receive and guide the discharged filling 1 carrier, .means for mounting said chute on the loom frame and permitting it to yield both forwardly and rearwardly from its normal position whereby the said chute may contact and yield forwardly from its normal position with the lay of the beat up and whereby the said chute may yield rearwardlyfrom its normal position if the discharging filling carrier be i caught between it and a moving part of the loom.

I at its upper edge to catch th trailing end of the discharged filling carrier.

4. In a weft replenishing loom a lay provided with a shuttle box and having an opening therethrough to permit the discharge of the abandoned filling carrier, a chute mounted on the loom frame and located beneath said opening when the lay is in position for transfer, the said chute acting to receive and guidevthe discharged filling carrier, and fillmg retaining means upon the upper edge of the chuteto catch the trailing end of the discharged filling carrier.

n a weft replenishing loom a lay pro-- vided with a shuttle box and having an opening therethro'ugh to permit the discharge of the abandoned filling carrier, a chute mount- ,ed on the loom frame and located beneath said opening, when the lay is in position for transfer, the said chute acting to receive and guide the discharged filling carrier and serrated at its upper edge to catch the trailing end of the discharged filling carrier.

.In testimony whereof, I have signed my name to this specification.
