Abstract: 13,668. Haidekker, A., and Berth¾ty, J. June 18. Shuttleless looms for weaving wire fabrics. The warp of the fabric is composed of two wires 1, twisted together between the weft 2, which consists of single wires bent in undulatory manner. Back-bearers.-The warp wires 1 run from spools, and are coiled several times round a grooved roller 4. Warp tension, regulating. - Connected with the roller 4 is a pulley wheel against which brake blocks are pressed by a band 34, operated through a lever by a draw-bar 37 and hand-wheel 38, Fig. 3. Warp wires, doubling and twisting; shedding- motions; beat-up motions.-Each pair of wires 1 is drawn through a tube 6, Figs. 3 and 10, axially adjustable in and rotating with a hollow axle 7, and then through a revolubly-supported box 17 and a hollow axle 10, on which is placed a revolving head 11 formed of two side pieces 12, between which are supported four rollers 13, 18. The hollow axles 7, 10 are rotated together alternately in opposite directions by worm-wheels 98, 99 operated by suitable mechanism, in which the alternate motion is produced by a rocking toothed segment actuated by a cam and operating a spurwheel. After each rotation, the head 11 is vertical, and, as the wires 1 pass between the rollers 13 and over the rollers 18, a shed is thus formed. When the weft has been introduced, a slide 53 is moved forward, through connecting-rods and levers actuated by a cam, and with it a fork 20, of which the prongs 21 carry forward the weft wire into the end 28 of the shed. The hollow axles 7, 10 then rotate and twist the warp wires behind the weft just introduced, the length of wires twisted being determined by the position of the edge 16 of a bar 15, which, fastened to the box 17, has been moved forward by a slide 57, actuated in a similar manner to the slide 63. When the twisting is completed, the slides 63, 57 are drawn back. The wires 1 are alternately twisted and untwisted behind the tubes 6, which are free to slide in the axles 7 to allow the wires to be drawn forward when twisted. Weft, supplying.-The weft wire 2 runs, frdm a spool, between guide-rollers and toothed wheels 104, which crimp the wire and project it through a hole in the frame to guides 22, 23. The toothed wheels 104 are actuated from a rocking toothed segment, operated by a cam. The lower guide 22, Fig. 10, is funnel-shaped, and the upper guide 23 forms a closing-piece. When the fork 20 moves forward, flattened axles 24, 25 are turned, and the guides are displaced to allow the weft wires to pass out. The axles 24, 25 are turned by a rod fixed to the slide 57 being pushed between and separating cranks provided with antifriction rollers and keyed on the axles. Weft, cutting.-The weft wire is cut at the hole in the frame by a knife actuated by a projection from the axle 25, so that the weft may be freely drawn forward by the forks 20. Circular cutters 137, driven from a roller 29, cut off the weft wire ends uniformly, and similar cutters may be placed to cut the fabric in various places, if desired. Take-up motions.-The finished fabric is drawn uniformly forward by the roller 29, which is provided with cross and longitudinal grooves for the warp and weft wires, and is driven by spur and bevel gearing. The fabric is rolled upon a cloth roller which is driven in the following manner:- A sprocket-wheel is driven by a chain from the shaft which drives the roller 29, and with it rotates a loose disc which is pressed against friction clutches on another disc by a forked anglelever, the amount of pressure being adjusted by a hand-wheel. The second disc drives the cloth roller through spur-wheel gearing.
