Specification of Letters Patent. v Patented Jan, 21 1919.

Application filed September 17, 1917. Serial No. 191,671.

To all whom it may concern:

Be ,it known that I, ALONZO E. RHOADES, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in FiIIingEnd-Retaining. Means for VVeft-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to weft replenishing looms preferably of the automatic type and its object is to provide means for catchingfilling carrier passes.

These and other objects of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

Figure 1 is an end elevation partially in vertical cross section of so much of an automatic weft replenishing loom ofthe Northrop type as is necessary to a disclosure of the present invention with a preferred form of the said invention embodied therein;

Fig. 2 is a front elevation of the transfer end of the lay shown in Fig. 1 together with a portion of the picker, the picker guide, and the chute;

Fig. 3 is a detail in plan of a the construction shown in Fig.2.

The presentinvention is not concerned with the particular construction oroperaportion of V tion of the general features of the loom to which it is applied. For convenience of illustration the invention is shown in'the preferred form selected as embodied in an automatic filling replenishing loom of the well known Northrop type. v.

In this type of loom the frame or loom side 1 supportsat the "transfer end obthe tions looma hopper stand 2 upon which is mounted a rotary hopper 3 carrying the supply of fresh filling carriers 4, The lay 5 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 downwarddischarge of an abandoned filling carrier when the shuttle is boxed at the transfer end of the 100m.

A transferrer 8 is pivotally mountedon thehopper stand and provided with a'dog 9 which upon-the call for filling replenishment is lifted into the pathof a hunter 10 carried by the lay thus causing the transferier to force a fresh filling carrier, in this case a bobbin, from the hopper 3 into the shuttle and-thereby discharge the abandoned or exhausted filli'ngcarrier or bobbin in the shuttle down through the opening 7. e filling extending from the The end of th 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 back through the eye of the shuttle and clear of the shuttle or it is liableto be. caught by the shuttleor by the fresh filling carrier and dragged back into the shed and oven into the cloth causing an imperfection. v V

this im'ention mechanism is provided toficatch and retain this filling end as the filling carrier is discharged from the shuttle andprevent it from being dragged back into the shed by the shuttle or the fresh fill-' ing carrier. I T u The, main mechanismprovided for this purpose is mounted on the lay and in the preferred form illustrated consists of a plate 11 having a serrated edge 12 with the serraointing away from the shed, This plate s slotted at 1 3 and secured to the lay by pins 14 passing through the slots, thus permitting theplate to move in and out or transversely upon the lay.

Alever 15 is fulcrumed upon avertical pin 16 carried by the lay and at one end is pivoted at, 17 to the plate 12 and at the other end 18 is curved to project slightly in front of'the bunterlO whichf naybe notched or slotted as shown to receive thi sendof the lever.- A spring 19 abuts afixedportion of the lay and is seated in a socket 20 on the end 18 of the lever and thus acts normally to project the plate 11 rearwardly into the opening 7 through which the discharged filling carrier passes. y

The serrated edge ofv the platen must project into this opening 7 in order that it may catch and retain the trailing filling end. Preferably the to withdraw this serrated edge from the opening or otherwise it might be hitby the discharging filling carrier thus causing damage and breakage of the parts. erably, therefore; means such as illustrated are provided for automatically withrhrawing the plate out of the path of the disc arging filling carrier.

It will be seen that when the call for replenishment takes place and the dog 9 is elevated and the lay heats up, the end '18 of the lever will he first struck by the dog 9 thus'. withdrawing the plate 11 from the opening 7 justin time to get it outof the way before the transferrer-S forces in the fresh abandonedfilling carrier down through the opening 7. Immediately thereafterthe lay moves rearwardly, the dog disengag'es the hunter and the spring '19 acts to restore the plate 11 to its inwardly projected position and the trailing end of the filling drags over the serrated edge and is caught and retained thereby.

The mechanism thus described maybe sufficient of itself to catch and retain the filling end so that it will not be caught and drawn back by the shuttle or the fresh filling carrier into the shed but in addition this inven tion provides in combination therewith filling-retaining means on the .upper edge of the chute which means in connection with other features is made the-subject of an other application Serial No. 1915673, filed September 17 1917.

The chute comprises a metal plate 21 pi-votally mounted on a horizontal stud 22 carried'by a bracket 23 secured to the loom side. '1: he stud 22 is surrounded by a helical spring 24: connected at one end to the stud and at the other end to the plate and aclin'g to swing the chute 21 yieldingly rear- \vardly.v i

The means for catching and retaining the filling carried by the upper edge of the chute is provided. in the serrated edge illustrated in which the serrations protei a bi point away from the shed.

'lhe chute stands normally in the position illustrated in. Fig. 1; As the lay heats,

up it. contacts with the upper edge of the chute on the rear wall of the opening 7. the

'chute yielding toperniit this contact. Upon transfer taking place lhe filling carrier passing through the opening T- contacts with the inclined chute 2 and guided down thereby into a suitable receptacle. As the filling carrier passes down the chute the la moves rearwardly and the trailing end vXlifiltllllg plate must be movable r Preffilling carrier and thereby forces the into said opening to catch and retain trailing end of drawnback into the shed,

either .in the'means specifically shown as the serrated ed e of the plate mounted on the lay or in t e combined means specifically shown as the serrated edge of the said plate combined with the serrated edge of the chute, means for preventing the end of the what I claim as new and desire to secure by Letters Patent is 1. In aweft replenishing loom, a lay pro- .vided with a shuttle'box and having an therethrough to permit the disopening of the abandoned .filling carrier,

charge means mounted on the lay and projecting the trailing end of said filling carrier after it is discharged, and means for temporarily withdrawing. said catching means out of the path of the discharging filling carrier.

2. In a weft replenishing loom, a lay providedwith a shuttle box and having an opening therethrough to permit the discharge of into said opening to catch and retain the trailing end of said filling carrier after it is discharged, and means operated by or the abandoned filling carrier, means mounted on the lay and projectingthrough the replenishing action of the loom temporarily to withdraw said catching means out of the path of the discharged filling carrier.

v3. In a weft replenishing loom, a lay provided with a shuttle box and having an openingv therethrough to permit the discharge of the abandoned filling carrier,

meansmounted onthe lay and projecting intosaid opening to catch and retain the said. filling carrier after it is.

discharged, and a chute located beneath said opening to receive and guide the discharged filling carrier and having its upper edge providcd with filling retaining means to catch and retain the said trailing end.

nation of features as set forth in claim 4 together with means acting to permit the said chuteto contact with, and move forwardly upon the beat up of, the lay.

6. In a Weft replenishing loom a. lay provided with a shuttle box and having an opening charge of the abandoned filling carrier, a plate provided with a serrated edge and horizontally mounted on the lay with its serrated edge projecting into said opening to catch and retain the trailing end of said therethrough to permit the dis filling carrier after its discharge, means for yieldlngly projecting said plate rearwardly, and means operated by or through the re plenishing action of the loom for tempt rarily moving said plate forwardly to withdraw the serrated edge from said opening during the passage of the filling carrier therepast In testimony whereof, I have signed my name to this specification.
