PATENT OFFICEo CLOTH-BEAM FOR Looms.

SPECIFICATION forming part of Letters Patent No. 342,148. dated May 18, 1886.

Serial No. 157,080. (No model.)

To aZZ whom it may concern.'

Beit known that we, HARRISON UNDEE- WOOD and SI-IAnLEs SOHWETZEE both of the city, eounty,and State of New York, have invented certain new and useful Improvements in OlotlrBeams for Looms, of which the following is a full, clear, and exact description.

This invention consists of a cloth-beam upon which cloth is to be wound as it is woven, and from which it is to be subsequently removed, constructed in two corresponding semicylin drcal parts attachable to and detachable from a revolving shaft, and provided with an outer casing, substantially as hereinafter described and shown.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding pnrts in all the figures.

Figure 1 represents an end elevation of our improved cloth-beam mounted upon arevolving shaft, shown in section, on the frame of a loom for weaving. Fig. 2 represents two fragments of a sectional cloth-beam in elevation, the outer casing thereof being in section on one ofthe fragments to show its thickness and the screws by which it is secured to the beam, one of the fragments being mounted upon a supporting-shaft,to which it is clamped. Fig. 3 represents a fragment of one end of a clothbeam, showing a clamping device thereon in elevation, by which the sectional beam is to be clamped upon a supporting-shaft, a section of which shaft is also shown in elevation. Fig. 4 is a detail View representing a hook and pin, by which the two semi-cylindrical parts forming the beam are hooked together at the ends opposite to the ends on which are hubs to be clamped to the shaft, the shaft being shown in section.

A in the accompanying drawings represents a shaft supported in suitable bearings on the fra-me of a loom Afor weaving cloth. Upon this shaft is mounted our improved clothbeam, which is composed of two corresponding semi-cylindrical parts, C O', which are clamped to the shaft A by means of two semicylindrical hubs, hy 7L', thereon, so as to be revolved to receive the web of cloth as it is woven and delivered to the beam by the loom.

Projecting laterally from the hubs 7L Zt. are

i anges Z j, to which is fitted a clamping-screw,

D. This screw D is provided with a shoulder,

7e, and collar Z, to receive between them the flange of the hub h. The lower end.j',of this clamping-screw D terminates with a screwthread to engage with a corresponding female screw formed in the fiangej, by means of which the two flanges z' j are drawn together to clamp the hub formed of the two semi-cylindrical parts li h' around the shaft A, as represented in Fig. 1. v

In order to introduce the clamping-screw D into the flanges i j, so as to draw the two hubs 7L h together to clamp around the shaft A, the flange i is recessed,so as to receive the shank of the screw D between the shoulder k and collar Z, as shown in Fig. 1.

Vhen it is desired to loosen the end pieces, a b c cZ,ofthe hubs h h', so that the beam may revolve upon the shaft independently, the collar Z serves to spread the angesi j apart when the elampingscrew D is turned outward, as represented in Figs. l and 2. The two semicylindrical parts C C are provided with the hubs hhnpon one of their ends only, their opposite ends being connectedby a hook, p, and pin p', as shown in Fig. 4. The semicylindrical parts O C are covered with a thin outer casing, e, of metal, with its two ends terminating at the edges of the parts C C on the side next to the clamping device, and secured to the end pieces, c b c eZ, of the parts O C by screws f along their edges, as shown in Figs. 1, 2, and 3. By this casing e the two part O O are held together on the side e when the hubs ZL h are loosened on the shaft A, so that the beam may revolve independently on the shaft and be removed therefrom and replaced at pleasure.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- A clotlrbeam for looms, consisting of two corresponding semi-cyli ndrical parts,O C,pro vided, respectively, with sectional hubs h h', projecting from their ends,with lateral flanges i j, and having a clampingscrew, D, having a shoulder, k, and collar Z, substantially as and for the purpose herein set forth.
