    Abstract: 15,619. Stewart, W. G. Nov. 5. Shuttleless looms ; smallware looms.-In a loom for weaving tapes and braid, each weft needle 21, Figs. 1 and 2, is arranged and operated so that it first projects the weft threads transversely through the warp sheds, then moves towards the fell of the cloth, and then transversely through the shed so as to beat up or move the successive picks of weft threads into position, thereby dispensing with the beating-up reed. A second needle 22 takes a loop 67, Fig. 8, of the weft thread 60 and draws it back through the previously-formed loop 62, which is shed from the needle 22 as it recedes through a groove in the bar 14, over which the woven fabric parses. The needles 21, 22 are carried by bars 24, 25 slidably arranged on the breast beam 8 one above the other, the needles 21 projecting slantingly from the carrier at one side of the cloth, while the needles 22 are arranged on the opposite side of the cloth and project horizontally. The bar 24 is moved longitudinally against the action of a spring 37 by a cam 28 on an inclined shaft 29 driven by bevelgearing from a shaft 33, and cams 39, mounted on a shaft 40 driven from the shaft 29, move the bar 24 transversely towards and from the fell of the cloth. The needles 22 are reciprocated longitudinally against the action of springs 47 by cams 46 on the shaft 40. Each weft needle 21 has a raised portion 57 adjacent to its eye to permit a part of the adjacent needle 22 to pass between the body of the needle 21 and the thread 60 extending from its eye to the fabric. The chain of loops formed by the needle 22 forms a selvedge at one edge of the fabric, and a selvedge is formed at the opposite edge by the loops which connect the adjacent warp sheds. The weft thread 48, Fig, 2, passes from a spool 49 to a pair of tension disks 52 on a bracket 53 on the bar 24 and through the eye of a spring take-up arm 54 to the eye of the needle 21.
