Abstract: 19,550. Schmidt, O. Sept. 1. Endless fabrics; wire fabrics ; smallware.- Endless straps and bands of cotton, camel hair, hemp, wire, or other material are produced in any required width and length by winding for each strap a single warp helically round the necessary loom rollers so as to form a band of warp of the required width, uniting the two ends of the warp, and interweaving weft with the band of warp in the usual manner. Yarns, warping; looms, general arrangement of ; backbearers.-The warping, is effected in the loom, by passing single warps from spools, corresponding in number to the straps to be woven, over a beam a, rollers b, c, and a tension roller d, and back to the beam a, where the free ends of the warps are provisionally knotted to the parts of the same warps running on the beam a. The beam a is then rotated by means of a disk e, whereby the warps are drawn from the spools and are warped in sections over the rollers. When the required widths are warped, the beam a is stopped, and the provisionally-knotted ends of warp are loosened and are joined to the other ends of the same warps. The roller d is then moved towards the beam a to slacken the warps, and back-bearers h, i and guiderollers f, g are passed through or under the band of warps and inserted into suitable bearings. The lay is pivoted to the lower part of the frame as shown, the rollers b, c are mounted in the upper part of the loom, and the warps and woven fabrics pass over the loom. The loom is driven by power in the usual manner. Loom healds ; lays ; reeds.-The healds k, which consist of rods, can be disconnected and have open thread-eyes, into which the warps can be readily inserted. The reed m is removable, and is inserted into the lay after the yarn is warped, whereupon the lay-cap is screwed on to the lay to hold the reed in position. Looms, warp tension regulating in; let-off motions; take-up motions; breast beams.-The tension roller d is mounted in a carriage s, which runs on rollers r in a groove in the frame. Chains v are connected to the carriage and pass round chainwheels w geared to a wheel y, which can be rotated by a hand-crank z. Rotation of the wheel y is retarded by means of a brake-wheel and a spring-actuated brake z<1>, so that the action of the brake must be overcome before the roller d can be drawn towards the loom by the tension of the warps. During the weaving operation, the rotation of the beam a is retarded by a brake n, and rollers p, q are pressed tangentially against the regulating roller o and the beam a by means of hand-screws, to prevent the warps and fabrics from slippirig on the rollers. The regulating-roller o constitutes the breast beam. Looms, hand-power.-When the woven fabrics approach the healds, the loom is stopped and the motion of the healds is made as small as possible, so that the weaving may be continued for some time by hand-power. The healds are then removed and the weft is inserted into the unfinished parts of the straps by means of needles or other suitable tools. Loom framework.-The bearings of the various rollers are so constructed that the rollers can be readily removed to allow the woven straps to be taken away from the loom. The transverse beam at the top of the loom is bolted to the frame at a<1>, b<1>, so that it can be loosened at b<1> and turned as on a hinge at a<1>.
