The rear end of the threader is cloth, can be readily removed by hand withprovided with a guard 8 which overlies the out causing an imperfection in the weave. path of the filling and serves to prevent it A further object of the invention is to from being thrown from the threader. provide a thread cutter of this type which. The rear end of the threader is provided 50 can be readily applied to usual types of with an extension 9 which is bent upwardly threaders. and this extension, together with the lower 10.3

A further object of the invention is to prowall of the threaderis provided with a slot vide a. cutter of the character which can be 10 which extends beneath the cutter which secured within the threader by the same will hereinafter be described. The body of the shuttle is provided with a recess 11 which lies beneath the threader and the slot 10 to enable the running bight of the filling to be The upper portion of the body of the cutter desirably is curved and the crest 14 of the curve lies substantially in the plane of the axis of the thread eye of the shuttle so that this curved surface serves to support and guide the filling to the thread eye. The cutter is provided with an edge 15 Which s located below the horizontal plane of the axis of the thread eye and extends toward the chamber in the shuttle which receives the filling carrier. The blade preferabl abuts against the upwardly turned mem ers of the threader extension 9 so that the slot 10 in the latter, which desirably converges downwardly, against the central portion the cutting blade.

In the operation of the device, where the shuttle thread cutter fails to sever the filling running from the web of cloth to the filling carrier which is discharged during transfer, the ,first pick of the shuttle after transfer formsva running bend or bight 16 in the filling around the edge of the cutting blade as the shuttle moves across the lay. During the beginning of this flight of the shuttle the filling runs freely across the cutof the edge of ting edge as the shuttle approaches the selvage of the web of cloth. When, however, the shuttle passes the selvage the filling is drawn forcibly against the blade and severed. This action of the shuttle is illustrated in Fig. 3 in which the filling 17, which extends from the selvage 18 of the cloth to the discharged filling carrier, is illustrated as being bent sharply around the cutting blade 16. At this time the weight of the discharged filling carrier imposes a tension upon the filling 17 which acts in opposition to the tension upon the portion 19 of the filling extending from the selvage 18 to the blade so that further movement of the shuttle (to the left) causes the filling to be severed in proximity to the selvage of the cloth. By reason of this operation the severed filling end is only two or three inches long and if whipped into the cloth can be readily removed without causing an imperfection in the web of the cloth.

\Vhile it is primarily intended to employ the present invention in connection with the usual shuttle feeler thread cutter it will be obvious that the same will operate in the serves to direct the filling.

mannerabove described even in the absence of a shuttle feeler thread cutter.

It will be understood that the embodiment of the invention disclosed herein is illustrative and not restrictive and that various changes in form, construction and arrang ment of arts may be made within the spirit and scope of the invention, and further that the invention may be embodied in various other types of threaders than that particularlvillustrated herein.

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

1. A shuttle for automatic filling replenishing looms having means carried thereby actlng during the first pick of the shuttle after transfer to sever the filling extending from the web of cloth to the discharged filling carrier.

2. A shuttle for automatic filling replenishing looms having a cutter carried thereby acting by the movement of the shuttle during the first pick after transfer to sever the filling extending from the web of cloth to the discharged filling carrier in proximity to the selvage of the cloth.

3. A shuttle for automatic filling re lenishing looms having a filling carrier c amber, a rigid cutting blade presenting an edge toward the filling carrier chamber acting during the first ick after transfer to sever the running biglit in the filling which extends from the web of the cloth to the dispick after the transfer to sever the filling in proximity to the salvage of the cloth.

A shuttle for automatic filling re lenishlng looms having a filling carrier 0 amber, a threader having a slot in its bottom communicating with said chamber and a recess in the shuttle body underlying said slot, a cutting blade presenting an edge extending toward saidchamber, overlying the slot in said threader, acting during the first pick after transfer to sever the filling in proximity to the selvage of the cloth and filling guiding members extending upwardly from the bottom of the threader acting to direct the bight formed during thefirst pick toward the central portion of said cutter.

6. A shuttle for automatic filling replenishing looms having a filling carrier cham ber, a threader having a slot in its bottom communicating with said chamber and a recess in the shuttle body underlying said slot, :1 cutting blade presenting an edge extending toward said chamber overlying the slot in said threader acting during the first pick after transfer to sever the filling in proximity to the selvage of the cloth and means acting to secure both the threader and the cutting blade in the shuttle.

7. A shuttle for automatic filling replen= ishing looms having a filling carrier chamher, a threader to receive and guide the filling from the filling carrier to the eye of the shuttle provided with a slot in its bottom, a recess underlying said threader communicating with said slot, a cutting blade having a filling supporting and guiding portion located substantially in the horizontal plane of the shuttle eye and having acutting edge located below said plane extending toward the" chamber of said shuttle acting during the first )ick after transfer to sever the running biglit in the filling which extends from the Web of cloth to the discharged filling carrier when said biglit is in proximity to the selvage of the cloth.

In testlmony whereof, I name to this specification.
