2 Claims.

This invention relates to new and useful improvements in cloth rollers such as are employed on looms and on to which woven cloth is transmitted from the take-up roller. At present, conventional rollers must be reclaimed by unwinding the cloth from the same, or spare rollers must be kept on hand to replace those which are taken off the loom by the operator. quires considerable time.

The principal object of the present invention is to provide a roller which can be collapsed within the roll of cloth and easily slipped out and reassembled in a moments operation by the Weaver, thereby eliminating the necessity of spare rollers and the handling of the same from one department of a mill to another.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings Figure 1 represents a fragmentary side elevational view showing the roller.

Figure 2 is an. inside elevational view of one bar of the roller.

Figure 3 is an other bar of the are identical.

Figure d is an caps.

Figure 5 is a longitudinal through the roller assembled.

Figure 6 is a side elevational view of the roller collapsed.

Figure '7 is a cross sectional view.

Figure 8 is a cross sectional view showing the sections collapsed.

Figure 9 is an inside elevational view of one of the caps.

Figure 10 is a longitudinal sectional view through one of the caps.

inside elevational view of the roller, showing that both bars elevational view of one of the sectional view This obviously re- Referring to the drawings wherein like numerapart relation with flat sides facing and each provided in the longitudinal center thereof, on its flat side, with a plate 1 having ears 8. A pair of spacer rolls are journalled at their ends in the ears 8 of the plates 5, said rolls extending across said flat sides in peripheral engagement in the longitudinal center of the bars and spacing the bars apart at said center.

The end portions of the bars 5, 6 are reduced as at 9, 9 and are secured together in spacedapart relation by end caps H, I2.

The caps are substantially of the same con struction, and a description of one will suffice for both. Each cap is of cylindrical shape having a relatively thick end portion [3 formed with a squared socket M for receiving the usual spindle end. Each cap ll, l2 has a diametrically disposed web I 5 therein for interposition between the corresponding reduced end portions 9 of the bars 5, 6 and on each of these webs I5 is a U- shaped spring member I t, the leg portions of which exert pressure against the opposed sides of the bars 5, 6 when the end portions are inserted into the caps I I, I2.

The cap l2 has openings l2 therein registering with openings H) in the ends of the bars 5, 6 and a bolt H is disposed through these registering openings and equipped with a nut It. The bolt I! obviously serves to prevent any collapsing action of the bars 5, 6.

When it is desired to collapse the roller, all that is required is to take oil the nut l8 and pull out the bolt I1 and remove the caps H, l2. The bar 5, for instance, can be forced inwardly from the right and this will collapse the bars 5, 6 to the position shown in Figure 6 whereupon they can be easily removed from the roll of cloth.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A roller comprising a pair of solid bars of semi-circular shape in cross-section opposed with flat sides facing and spaced apart, a pair of spacer rolls mounted on said flat sides, respec tively, in the longitudinal center of the bars and extending crosswise of said sides in peripheral engagement to space said bars apart in the longitudinal center thereof, and a pair of cap sections securing the ends of said bars together at opposite ends of the roller, respectively, and provided with diametrical webs interposed between the ends of the bars to space said bars apart at said ends.

2. A roller comprising a pair of solid bars of semi-circular shape in cross-section opposed with flat sides facing and spaced apart, a pair of spacer rolls mounted on said flat sides, respectively, in the longitudinal center of the bars and extending crosswise of said sides in peripheral engagement to space said bars apart in the longitudinal center thereof, and a pair of cap sections securing the ends of said bars together at opposite ends of the roller, respectively, and provided with diametrical webs interposed between the ends of the bars to space said bars apart at said ends, and a pair of U-shaped springs straddling said webs and bearing outwardly against said ends of the bars and frictionally locking the caps to the bars.
