Abstract: 25,939. Hiller, G. Nov. 8. Warp threads, uniting.-In a warp-uniting machine, the old warp K, Figs. 2 and 27, having its ends secured by gripping-bars 8, 8<1>, is mounted on a carriage 1 running on rollers 206, and the new warp K', which is wound on the beam 2' and has its ends secured by gripping - bars 15<1>, 15<11>, is mounted on a carriage 15 supported by rollers 13, 13<111> running on tracks on the carriage 1. The warps K, K<1> are tightened by means of hand-wheels 85, 208, and the carriage 1 is then moved along rails 201 until it is locked in position by spring - pressed bolts 198 engaging notches 199 in the rails. The twisting-in carriage W, Fig. 1, which is drawn across the machine by a chain 25, is. brought into its correct position at the left side of the machine by turning the chain-wheel 26, and the carriage 15 is then moved laterally on the carriage 1 by means of a handle 24 to bring the extreme threads of the warps K, K<1> into the same vertical plane. When the machine is started by means of a rod 92 arranged to operate a friction clutch engaging the belt pulley 89, camoperated brushes 121, 121<1>, Figs. 11 and 27, mounted on the carriage W, engage the extreme threads in the warps K, K<1> and move them backwards, as viewed in Figs. 11 and 27, the adjacent threads being retained by the vertical arms of cam-operated bell-crank levers 101, 103, Fig. 11. Notched levers 128 then move the two separated warp threads farther backwards, while the brushes 121, 121<1> return to engage the next pair of warp threads, which are thereupon released by the levers 101, 103, the adjacent threads being kept back by levers 100, 102 arranged to work alternately with the levers 101, 103. The threads engaged by the notched levers 128 are seized near the clamps 8, 15<1> by tongs 153, 154; Fig. 27, and, after the threads have been cut by scissors, the tongs 153, 154 raise their ends, while the bent bar 136 holds them down at their point of crossing.The tongs 153, 154 introduce the raised warp ends between friction disks, which twist the warp' ends together in the manner described in Specification 25,515/07. Soon after the commencement of the twisting operation, the warp threads are released by the tongs and by the bar 136. The machine is provided with additional means for holding down the threads, consisting of bent wires 134, 135. The carriage W is moved across the machine intermittently by ratchet mechanism controlled by a vibrating finger, which bears against the extreme thread of the warp K and is so arranged that, when the carriage W needs to be fed to the right, the finger causes a square rod 65, Fig. 1, to turn, thus putting into operative position the pawl of the ratchet mechanism. If a warp thread breaks, or if all the warp threads have been united, one or both of a pair of fingers, which normally bear against the extreme left-hand threads of the warps K, K', turn from their normal position and put into action mechanism for operating the driving-clutch, so as to stop the machine. To the carriage W is pivoted a weighted indicator 73, Fig. 11, the lower end 74 of which rests against the edge of the new warp K'. By turning the handle 24, Fig. 2, from time to time, and thus moving the carriage 15, the operator is enabled to bring the indicator 73 into a vertical position, thereby bring- ing the warp threads about to be joined together into the same vertical plane.
