WARP-BEAM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 776,082, dated November 29, 190%.

7 Application filed July 8, 1904. Serial No. 215,706. (No model.)

To (I/ZZ/ whom, it flea/y concern.-

Be it known that I, ANTHONY J. OREILLY, a citizen of the United States, residing at Worcester, county of WVorcester and State of lVIassachusetts,have invented an Improvement in VVarp-Beams for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object to insure the accurate and quick clamping of the heads of a warp-beam to the bodies thereof in proper position to insure that the inner sides of the heads stand at right angles to the longitudinal axis of the beam.

Heretofore many plans have been devised for clamping and adjusting the heads on the ends of the beams, such plans usually employing webs and screws. In my invention I interpose a saddle between the head and beam, and bya clamping device, shown as a threaded bolt carried by the head and enteringa threaded part of the saddle, I cause a part of the head to be seated on a partof the beam on one side of its longitudinal center and a part of the saddle to be seated on the beam at the opposite side of the longitudinal center of said beam. The heads are shown as split, and the hub of each head is represented as chambered, the chambers being opened. next the beam, and the saddle, made preferably as a ring, enters said chamber and is maintained in position therein when the two parts of the head are clamped together.

Figure 1 shows a warp-beam made in accordance with my invention, the body of the beam being broken out centrally and one of the heads and the saddle being representedin section. Fig. 2 is an end view of the head and beam, the dotted line X representing the section for the head at the right end in Fig. 1.

The body A of the warp-beam is provided with usual metallic trunnions A, that extend from the end thereof and may extend entirely through the beam. These trunnions may be of any usual construction.

My invention resides chiefly in the construction of the heads of the beam. Each head comprises, as represented, two like halves B B, said halves being connected together to be applied to the beam by suitable bolts B ex. tended through webs of the heads, said bolts having suitable nuts B. Each head has its hub Z) easthollow, leaving that side of the hub next the body A of the beam open for the reception of a saddle (1, (represented in section and dotted outline, Fig. 1,) said saddle, as herein illustrated, circular in form. The saddle has a screw-threaded opening 0, and apart of the hub has an opening for the reception of a clamping device, represented as a boltl), that is extended loosely through the opening in the hub, the threaded part of the bolt entering the threaded hole in the saddle. The head of the beam has extended from one side thereof a friction-surface B, having an outturned rib b, said friction-surface receiving any usual brake, band, or cord commonly employed in connection with warp beams in looms.

The saddle having been applied inside the open hub of the warp-bea1n, said parts are applied to the end of the body A of the beam, and thereafter the clamping device 1) is turned, causing, as herein illustrated, the portion of the saddle at the upper side of the beam of the body A, Fig. 1, to be seated firmly on said body, and during the rotation of the clamping device the edges 3 and 4t of the hub at the lower side of the body A are seated against the said body. As the clamping device is turned it will be obvious that the saddle is forced closer and closer against the body of the beam at one side of the longitudinal center thereof, while the two edges referred to will be forced more and more firmly against a portion of said body at the opposite side of the longitudinal center of said body.

Having described my invention, what I claim, and desire to secure by Letters Patent, 18

1. A warp-beam head, combined with a saddle encircling the warp-beam, and clamping means to force a part of thesaddle against one side of the longitudinal center of the beam and a part of the head against the opposite side of the longitudinal center of said beam.

2. A warp-beam head having a hollow hub presenting an open space next the warp-beam, a saddle contained in said space and completely encircling the warp-beam, and a screw extended loosely through the hub of the head and engaging screw threads of the saddle whereby said saddle and head may be adjusted to fit the beam.

3. A Warp-beam head having a hub chambered and open next the warp-beam, and provided outside said hub with a friction-surface combined with a saddle located in the hollow hub, and means to move said saddle whereby ANTHONY J. OREILLY.
