Specification of Letters Patent.

Patented .hpri; 30, 1907.

Application filed A ril 27, 1906. Serial No. 313,955.

To all whom, it may concern:

Be it known that l, CONSTANT AILLERY, a citizen of the United States, and a resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented an Improvement in Loom-Shuttles, 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 to loom shuttles, and it has for its particular object the production of novel and effective means for exciting the proper tension on the yarn or thread as it is drawn through the shuttle-e ye.

In my present invention I have provided a friction device around which the thread passes in contact as it turns from the longitudinal passage in the shuttle to the side delivcry-eye, the drag exerted upon the thread by engagement with the frictiondevioe keeping such thread under proper tension.

I have so arranged the friction device that it can be moved to bring a fresh engaging surface into acting position when the old surface becomes worn.

The various novel features of my invention will be fully described in the subj oined specification, wherein one practical embodiment of my invention is set forth, and particularly pointed out in the following claims.

. Figure l'is a top lan View of the delivery end of a loom-shutt e, with one embodiment of my invention applied thereto; Fig. 2 is a side elevation of the threading device or block detached, to more clearly illustrate the tension-producing means; Fig. 3 is a front view of the threading-block; and Fig. 4 is. an

enlarged cross-sectional detail on the line 4=-4, Fig. 2.

I have herein shown my invention enibodied in a loom-shuttle of the automaticallyself-threading type, the threading device or block being substantially that shown in United States Patent No. 769,914, granted September 13, 1904 to Northrop, but the particular threading device is not material to my invention, and the latter may also be used in other forms of loom shuttles.

Referring to Fig. 1 the shuttle-body 1 having an opening 2 to receive the filling-carrier or bobbin 3, and the side delivery eye 4, may be all of usual construction. The metallic threadingblock 5 has a longitudinal threadpassage 6 having a slot-lil-ze thread enirsnce 7 at its rear end, and at the from: end of the passage an inclined horn 8 is provided, Figs. 2 and 3, on the under side of the head 9 which overhangs the deliveryeye. A beak it) crosses the front open end of tho thread-pas sage and is overlapped by a shield 11 the filllug-thread when drawn into the thread-passage 6 and under the beak, being directed downward automatically by the horn 8 and adjacent parts of the threading block into the delivery-eye.

In my present invention I have provided a friction device which engages the-thread as it passes from the thread-passage and turns in a lateral direction to the delivery-eye. A

steel pin' 12 depends from the threadingblock adjacent and back of the horn, and ordinarily such pin serves as a fixed guide for the thread. I provide this pin or guide with a covering of friction-producing material, such as felt, flaimel, or other suitable mate rial, the rough surface thereof acting upon the thread and exerting the requisite tension producing drag or strain thereon. A convenient mode of applying the material is to cement or otherwise secure a piece 13 of the material upon 'a cylindrical sleeve 14, slipped onto the pin and held thereon with a frictional fit so as to be immovable or held from rotation under normal conditions. It is unnecessary to head or upset the end of the pm as the bottom of the recess in the shuttlebody, out to receive the threading block, will engage the lower end of the friction device and hold it in lace. When one portion of the surface of t we cylindrical friction produc ing covering 13 becomes so worn that it will not act properly upon the thread the block can be removed from the shuttle and the covering turned slightly by hand to present a fresh friction surface to engage the thread.

From the location of the friction device it will be seen that the filling-thread must draw across and partly around the same as it travels along from the front end of the threadpassage to the delivery-eye, and hence the tension is always exerted properly during the delivery of the thread. I

The construction herein shown and de" scribed may be varied or modified in different de tails by those skilled in the art without departing from. the spirit and see c of my in vention as set forth in the appen ed claims.

Having described my invention What I claim as new and desire to secure by Letters Patent isi i 1. In a loom-shuttle having a ileliver ve \'e and adap'ed to contain a suppl of filling, means to direct the iilling-tliread to theeve, a thread guide around which the thread passes to the (.leliverv-eye, and acovering of friction producing material surrounding and normally innnovable on said guide and acting upon the threadv v 2. In a l0om-shuttle havinga side deliv er v-e, re and a longitudinal thread-passage, a fixed thread-guide around whieh the fillingthread passes as it travels from said passage to the delivery-eve, and a covering oflfriction producing material mounted on and normally held from movelnem relative to said guide to engage the thread, said covering being adapted to beturned on the guide to present a fresh engaging surface when de-' sired.

In testimony whereofll have signed my name to this specification, 111 the presence of two subscribing witnesses.
