FILLING-END-WITHDRAWING MEANS FOR WEFT-REPLENISHING LOOMS."

Specification of Letters Patent.

Patented May "2, 1918 Application filed September 17, 1917. Serial No. 191,701.

; a citizen of the United States, residing at Atlanta, county of Fulton, State of Georgia, have invented an Improvement in Filling- End-lVithdrawing Means for lVeft-Replen: ishi'ng Looms, of which the following des'cription, in connection with the accompany- 7 ing 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 engaging and withdrawing the trailing end of the abandoned filling carrier after its discharge from the shuttle in the operation of replenishment so that it will not be caught and carried by the shuttle or the fresh filling carrier into the cloth upon the succeeding pick.

This object is secured in the present invention by means mounted upon the lay and operated by the picker and acting when struck by'the picker to engage and Withdraw the trailing end of the filling from the shuttle.

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.

In the drawings,

Figure l is a front elevation of so much of the transfer end of an automatic wei't replenishing loom of the Northrop type as is necessary to a disclosure of the present inrention with a preferred form of the said invention embodied therein;

Fig. 2 is a top plan view partially broken away and partially in' horizontal cross section of a portion of the construction illus* trated in Fig. 1.

The present invention is not concerned with the particular construction or operation of the general features of the loom to which it is applied. For convenience oi? illustration the invention is shown in the preferred form selected as embodied in an automatic filling replenishing loom of the well known Northrop type.

In this type of loom the frame or loom side 1 supports at the transfer end of the loom a hopper stand 2 upon whichis mounted a rotary hopper 3 carrying the supply of fresh filling carriers 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 downward discharge of an abandoned filling carrier When the shuttle is boxed 'at the I transfer end of the loom. j The usual transferrer 8 pivotally mounted on the hopper stand at 9 is actuated upon the call for filling replenishment to force a fresh filling carrier, in this case a bobbin, from the "j j hopper 3 into the shuttle l0 therebeneath on v the lay and thereby discharge the abandoned or exhausted filling carrier or bobb the shuttle-down through the open The shuttle is picked back and the lay by the usual pickers one oi shown at 11. This picker projects through the opening 7 and operates It is shown in Fig. 1 at its extren hand position when the shuttle is be swings from this position to the left t. the shuttle across the lay.

The end of the filling extending or ing from the abandoned filling 1 through the eye of the shuttle is, in i eeler looms, usually severed by suitable rue-chm nism adjacent the nose of the shuttleand this severed end must be drawn back through the eye of the shuttle and clear of the shuttle or in other words it must bewithdrawn from i the shuttle or it is liable to be caught by the shuttle or by the fresh filling carrier and dragged. back into the shed and Woven into the cloth causing an imperfection.

In this invention means are provided mounted upon the lay and preferably actuatcd by the picker to engage and Withdraw co from the shuttle the trailing end of the dis charged filling carrier and thus prevent'itl from being dragged back into the shed by the shuttle or the fresh filling carrier. 1

The preferred form of mechanism illustrated for this purpose is shown as a device comprising a fixed member mounted on the I lay in frontof the opening 7 and a movable to a stud 15 and by which it is conveniently 5110 pivoted in the finger 12 and in a bracket 16 secured by the bolt 13 to the lay and dea :2 WW8 'asshown atfull lines'in Fig. 2. When the icker 11 moves to the left it comes imme-4;

The operat on'of the inventionwill now be apparent. .When' replenishment takes a place and the exhausted and abandoned filling carrier is discharged from the shuttle 10 it passes down through the opening ,7 andfalls into a receptacle usually provided beneath the loom, The trailing end of the filling if not withdrawn from the shuttleby the filling carrier itself extends back through the eye' of the shuttle and between the shut-' tle and the .box. From the eye the end extends down through the opening 7 in front of-the loop-14.. If it remains in-this posiand with a quickjerk swingsthe loop into the position shown in dotted lines'in Fig. 2 thus causin the loop to engageit-he trailing end of quick jerk through the ,eye of the shuttle and" from between'the shuttle and the box thus freeing it entirely from the shuttle.

Having fully described my invention, what I claim as new and desire to'secure by Let- 'ters Patent is:
