Abstract: 20,529. English Sewing Cotton Co., and Bennett, A. Sept. 11. Threads.-A machine for piecing or splicing threads, shown in plan in Fig. 1, comprises creels arranged at the front and back of the machine so that the pairs of threads to be pieced run transversely across the machine and any number can be pieced without increasing the distance the piecer has to reach from the front of the machine. A number of pairs of spindles i, i<1> and pillars p are provided for the pairs of threads n to be pieced, one thread of each pair coming from a bobbin x at the back creel, through a pillar p to the top of the spindle i, and the other from a bobbin w at the front creel, through guides y, y<1>, an intermediate tension device 25, the spindle i<1> and its connected wheel h, to the pillar p. The threads are clamped in the pillars by plate springs q actuated by cams &c. 31 on a manually-operated rod r, and in the spindles by catches or spring clips m. Each spindle and its driving-wheel h are slotted for the passage of the thread, and are driven by bevel, spiral, or friction wheels from a shaft b<1> driven by pinions e, f from the shaft b carrying two pairs of fast and loose pulleys c, c' and d, d<1> driven respectively by open and crossed belts. A rack v operating two knock-off motions is driven by pinions u, t, s from the shaft b, and, after the threads are clamped as above described, the machine is started by moving the setting-on handle 1, Fig. 2, of the open belt and a certain amount of twist is taken out of each thread by the rotation of the spindles, the machine being then automatically stopped by the first knock-off motion. The operative pieces the threads together and the machine is run in the reverse direction by moving the setting-on handle 2 of the crossed belt until the twist taken out is put into the pieced threads again, when the second knock-off motion automatically stops the machine. The handles 1, 2 of the belt forks 1<a> 2<a> are carried by sliding collars 4, 5 mounted on a bar 3, the collars allowing of only one belt being on a fast pulley at one time; the collar 4 of the first knock-off motion is connected by a bar 6 and stay 8 to a bar 7, and as the open belt is put on the fast pulley c, a weighted lever 9 is caused to engage a slot 7<a> in the bar 7 and hold the belt on the pulley against the action of a spring 10. The lever 9 is actuated, to allow 'the spring 10 to move the belt on to the loose pulley, by a peg carried by the rack v. The second knock-off motion collar 5 is similarly actuated by a spring and a peg on the rack v, the pegs being adjustably mounted in a slot in the rack so as to knockoff when the desired number of twists have been taken out and put in again; a scale is provided on a stationary part of the rack, and a second scale 13<a> is provided in order that the operative may see that the knock-off motions are acting at the correct times. The inclination or height of the baseboard k may be adjustable and the hinged bracket o carrying the pillars p is adjustable for different qualities or counts of thread. The tension device 25 consists of a series of pins 26 carried by a bar held with the pins normally out of contact with the threads by an arm 28 and stop 29; the arm is released from the stop when twist is being inserted into the spliced threads, and a spring 27 causes the pins to catch the threads to tension them and keep them off the gears g, h. The back bobbins are placed on a creel 20 which may be in any number of tiers, any tier being moved into position by a hand-wheel 21 and pinion and rack 23 assisted by weights 24. The springs 10 actuating the knock-off motions may be attached to the sliding bars 7 which would then be provided with slots engaging the stays 8, so that the operative could shift the belts on to the loose pulleys without disturbing the knock-off motions.
