JAMES ll. NOR-THROP, OF HOPEDALF, MASSACHUSETTS, ASSIGNOR TO GECIRGE DRAPER- d' SONS, OF SAME PLACE.

TH READ=PARTER FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 556,688, dated March 17, 1896. Application filed November 18,1895. Serial No. 569,283. (No model.)

To all whom it may concern:

Be it known that l, JAMES ll. NORTHROP, of llopedale, county of Vforcester, State of Massachusetts, have invented an improvement in Thread-Parters for Looms, of which the following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing like parts.

This invention relates particularly to that class of looms wherein the shuttle is autom atically supplied with a fresh filling-carrier when the illing is spent or exhausted to a predetermined extent, and has for its object the production of means .for severing or cutting the end of filling leading from the selvage of the cloth to the filling-supplying mechanism when a fresh iilling-carrier has been inserted in the shuttle, as in United States Patent No. 529,940, granted to me November 27, 189i. lf this thread is not positively out or severed it will break as the cloth is wound upon the roll, probably leaving a long end which tends to weave into the edge of the cloth and make a ragged-looking selvage.

l have herein shown the severing device as composed of two members, one of which is attached to the lay, the other preferably to the usual loom-temple, and so located that at each beat of the lay the two members will cooperate to engage a thread of filling which may enter between them and sever it adjacent the selvage of the cloth.

Figure l is a top or plan view of a sufficient portion of a loom to be understood, showing the filling-supplying mechanism and with one embodiment of my invention applied thereto. Fig. 2 is a detail View, partly in section, taken transversely to the lay, showing the severing mechanism in two positions; and Fig. 3 is a perspective view of the severing mechanism ready to sever an end of filling.

The lay A3, breast-beam A40, temple T, shuttle S, the filling-supplying mechanism, including the feeder a a to receive the lill ing-carriers F, the weft or filling end holder b2, the stud f, and the pusher f', mounted thereupon, may be and are all substantially as represented in said patent, the parts being in, practice operated as therein provided for.

l As provided for in said patent, when a fresh llin g-carrier has been inserted in the shuttle and the latter thrown across the lay A3, the end of the filling t will lead from the selvage of the cloth C to the filling-end holder b2, as shown in Fig. l, and as the cloth is wound upon the roll the end will break, usually leaving a long end. To obviate this long end of iilling l have provided a severing device comprising two co-opcrating members, one of which is shown as a casting m suitably se cured to the front of the lay outside of and adjacent the cloth selvage, and provided with a plurality of forwardly and upwardly inclined projections or ears m', with a space between them. The other member is herein shown as an extension n of the outer end of the temple-cap, downturned at n in the path of and to enter the space between the two projections m on the lay as the latter comes forward at cach beat, the two members passing by each other, as shown by dotted lines, Fig. 2.

As will be seen by reference to Figs. l and 3, the position of the two members is such that the filling end t will pass between them, and when the two members come together, as described, the filling-thread will be pressed in opposite directions, to readily sever or part it at such point.

The edges of the severing members do not have to be sharpened, nor do the parts have to intersect snugly, for the motion of the lay is so rapid (nearly two hundred beats per minute) that the filling willbe severed quickly, even if not at the rst engagement.

The rapid and repeated action of the severing members upon the iilling end cannot fail to sever it quickly and accurately quite close to the selvage.

It will be obvious that the member n' might be attached to some other fixed part of the loom rather than to the temple T, or to a separate holder; but as the temple is in the proper position l prefer to make use of it, forming as it does a simple and effective holder.

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

ICO

l. In a loom provided With automatic illing-supplying mechanism, the lay, and a severing device for the end of a fresh supply of filling, said device consisting of a member having a plurality of filling-engaging projections, an independent (3o-operating member to engage the filling on the opposite side thereof, and a stationary support for one of said members, the other member being attached to the lay, whereby When one of said members passes the other the filling held between them will be severed, substantially as described.

2. ln a loom, the lay, a iilling-severing member thereon provided With a plurality of adjacent iilling-engaging projections, a temple having an extension lying in the path of the movable member and to pass between the projections thereon, said extension forming a co-operatin g member, whereby said members pass each other in the path of and oppositely to pass between the Y JAMES H.
