409,050. Stopping the picking and take-up motions of looms. CAWTHRA, W., and CAWTHRA, M., 14, Clevedon Place, Ovenden Road, Halifax, Yorkshire. Nov. 12, 1932, No. 32022. [Classes 142 (ii) and 142 (iii).] After the loom has stopped, owing to weft breakage for example, a push rod 32 is operated until a recess 33 thereon engages a catch 34, a lever 31 and a shaft 28 being thereby turned. Levers 36 are thus operated to raise rods 38, 39, which stop the take-up and picking-motions, so that the loom may be turned over by the weaver without these motions functioning. Take-up motions.-The rods 39 operate lever mechanism 42, 45, 46, 49 whereby the take-up motion clutch 50 is disengaged. Picking-motions.-Heart-shaped tappets 3 at each side of the loom, fast on a shaft 1 rotating at the same speed as the crank shaft simultaneously operate arms 4, which are loosely mounted on the picking shafts 5, but are clutchable thereto by the engagement of teeth 9 on slidable clutches 10 with apertures in the arms 4 and in clutch members 8 fast on the shafts. The two clutches 10 are raised and lowered, to cause alternate picking from each side of the loom, by forks 13 on slidable shafts 11 controlled by levers 18, 17, one at each side of the loom. The levers 18, 17 are connected by a rod 20 and operated by a rod 21, and an eccentric stud 22 on a segmentally toothed pinion meshing with a quadrant wheel &c. 27 on the shaft 1. Both spindles 11 are simultaneously raised so that the picking is stopped, when the rod 32 is operated, slotted ends 40 on the rods 36 engaged with necks 16 on brackets 15 on the spindles 11 raising these. According to the Provisional Specification, the take-up catch may be operated by means of a wire or rod so that this catch may be disengaged either simultaneously with or independently of the lifting of the spindles and clutches of the picking motions.
