LOOIVl-SHUTTLE.

Specification of Letters Patent.

Patented Aug. 7, 1906.

tle at the proper time, the incoming fillingcarrier engaging and ejecting the previous one from the shuttle, and more particularly the invention relates to such shuttles used on so-called feeler-looms. In such looms the filling change or replenishment is effected automatically prior to complete exhaustion of the filling in the running shuttle, so that the outgoing filling must be parted or cut to fa cilitate the threading of the new sup El for the shuttle and to prevent the ejected ling being woven into the cloth. Various means have been devised for effecting such parting of the old filling, and my present invention has for its object the production of novel and very effective means for parting such filling.

In accordance with my invention the outgoing filling is severed by or through the ej ection of the filling-carrier from the shuttle.

The various novel features of my invention will be fully described in the subj oined specification, and particularly pointed out in the following claims. Figure 1 is a top plan view of a loom-shuttle provided with one form of fillin -parting means embodying my invention, tie latter being shown in normal or inoperative position. Fig. 2 is an enlarged transverse section on the line 2 2, Fig. 1, looking toward the right. Fig. 3 is a similar view, but showing the parting means as o crating to part the filling of the ejected ing-carrier indicated by dotted lines. Fi 4 is an under side view of the right-hand en of the shuttle shown in Fig. l, and Fig. 5 is a perspective view of the movable member of the parting means detached.

The shuttle-body 1, having a lon itudinal opening 2 extended therethrou h om top to bottom, as hereinishownfifor t ejreception and discharge of a filling-carrier b, said fillingcarrier having annular projections 12 at its butt-end, Fig. 1 to be engaged and frictionally held by holdmg-j aws 3 in one end of the opening 2, and a threading device 4 at the opposite end of the opening, may be and are all of well-known construction.

The threading device is herein shown as of the automatically-self-threadin type, to thread the shuttle when a fresh fil ing-carrier is inserted automatically therein-as, for instance, in the Northrop loom, which forms the subject-matter of United States Patent No. 529,940, granted to Northrop, and other patents of later date. In Fig. 1 the side wall of the shuttle has a feeler-opening 5 for the intermittent entry of the feeler, WhlCh contacts with the filling and indicates the de me of exhaustion thereof, so that filling rep enishment may be effected prior to complete exhaustion of the filling.

Referring to Figs. 1, 2, and 3, the shuttlebody is cut out at 6 at the entrance to the threading device to form a guide for the filling t, Fig. 1, as it passes to said device from the tip or delivery end of the filling-carrier. In accordance with my present invention have provided the shuttle with filling-parting means adjacent such guide portion 6, sm means in the present embodiment of my invention comprisin a fixed member (shown as two parallel blades 7, fixed in the shuttle- Wood) and a movable cooperating member 8, adapted to swing or rock between them. The parallel blades 7 are cut out or concaved at their upper edges, as at 9, (see Figs. 2 and 3,) so that the filling maypass freely over the uper edges to'the threadin device, the blades being located in front of t 1e tip of the fillingcarrier and transversely to the path of the fillin The memberS has its inner edge concave as at 10, Figs. 2,3, and 5, and its lower end is bent and extended to form a foot 11, the inner end of the foot being provided with a cylindrically-bent portion 12, which loosely embraces a headed pivot pin or stud 13, firmly fixed in the shuttle-wood and substantially parallel to the longitudinal axis of the shuttle.

A spring 14 is coiled around the pm and one end is secured to it, its free end bearing against the foot 11, as in Fig. 4, the sp being so wound as to normally throw the b ade answmamawvnp- Sinto inoperative position, with its tip end 8? withdrawn into a'recess' or housing in the side wall of the shuttle. (See Fig. 2.) When in such normal inoperative position, the movable blade is held away from thepath of the circle I) in Fig. 2 indicating the normal relative position of the tip of. the fillingecarr-ier. When the filling is changed or replenished, the incoming filling-carrier strikes the one then in the shuttle and ejects it from the open bottom of the opening 2 in well-known manner, and as the ejected filling-carrier is discharged its tip hits the foot 11 and turns it and the blade 8 into the position shown in Fig. 3. The filling t, Fig. 1, is thus caught between the fixed and movable parting members 7- and 8 and cut or parted instantly and cleanly close to the tip of the filling-carrier and between it and the threading device, leaving avery short length of the old filling to be pulled out through the threading device and shuttle-eye. The chance of the old filling end fouling or twisting around theincoming filling is thus practically eliminated, and, further, there is no long end of filling hanging from the tip of the ejected filling-carrier. Immediately after the ejected filling-carrier has passed the foot 11 the spring 14 returns it and the member or blade 8 to normal position out of the way of the fresh filling.

So far as I am aware it is broadly new to part the old filling within the filling-receiving opening in the shuttle, and I believe it is also broadly new to part such old filling by or through the action of the ejected filling-carrier. Accordingly my invention is not restricted to the precise construction and arrangement herein shown, which is merely one practical embodiment thereof; but various changes or modifications may be made by those skilled in the art without departing from the spirit and scope of my invention.

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

1. A loom-shuttle provided with a threading device and having an opening therethrough to receive, and permit the discharge of, a filling-carrier, and a' thread-cutting device on the shuttle to cut the filling by or through discharge of the filling-carrier from the shuttle.

2. A loom-shuttle having means to engage and sustain -a removable filling-carrier and permit it to be ejected, and a thread-parting device carried by the shuttle and so located as to be operated by the tip of the filling-carrier when ejected from the shuttle, to part the filling near the tip of such filling-carrier.
