Abstract: 1617. Western Electric Co., [Western Electric Co.]. Jan. 20. Winding-machines; stop-apparatus, non-automatic; thread-guides.-In a winding-machine, particularly adapted for winding magnet spools or the like, the wire is guided to and fro across the spool s, Figs. 1 and 2, to be wound thereon, by a guide-roller g supported on a carriage 14 slidable along a track 13, parallel to the spool, and pivoted at 20 to a lever 17 slidably pivoted at 18 to the machine base and at 19 to a carriage 44<a> slidable along a track 16 parallel to the oppositely-moving portions 34, 35 of a driven belt. Two double-coil electro-magnets 40, 41 are mounted in the carriage 44<a> and are arranged, as shown, outside the belt portions 34, 35, and an armature or clutch member 42, pivoted in the carriage between the belt portions, grips one of the belt portions between itself and the magnet adjacent to the belt and causes the carriage and wire guide to be traversed. The direction of traverse is reversed at each end of the spool s by a hard rubber shoe 46 carried by the middle contact 45 of a circuitbreaking switch 45, 49, 50, Fig. 6. This shoe strikes against one or other of the circular spool flanges f and breaks contact between the parts 45, 49 or 45, 50, thus breaking the circuit, which is normally closed through both magnets, Fig 7, through the magnet 41 or 40, and causing the armature to be rocked over to the magnet 40 or 41 against which it grips the belt portion 35 or 34. The armature is yieldingly retained by a spring-controlled stud 44. The switch 45, 49, 50 is carried by a bracket 56<1> adjustable by a screw 57 and a screw and slot 56 upon a bracket 57<1> extending from the carriage 14, and when spools with square flanges are being wound, the switch is lowered so that the shoe 46 contacts with round nuts 53, 54 adjustably mounted on a fixed screw 55; the guide g is adjusted by means of a pawl 58 having a tooth 59 which engages one of a series of teeth in a disk 60 on the bracket 57'. The contacts 49, 50 are provided with springs 47, 48 adjusted by means of screws 51, 52 having hard rubber points passing through perforations in the contacts. The pivot 18 is carried by a nut 62 slidable in a slot 63 in the machine base and adjustable along a screw 65 by a thumb-piece 66. A worm on the screw meshes with a wheel 68 carrying a dial or indicator i having concentric graduated scales marked in thousandths of an inch and the pivot is adjusted until the diameter of the wire to be wound is opposite the zero point of the scale being used; if the inner scale is used, the gears 28, 29 through which the belt is driven are arranged as shown, and when the outer scale 73 is used, these gears are interchanged. The belt is driven from a motor-driven shaft 21, supporting the spool, through worm gearing 25, shaft'27, the gears 28, 29, and worm gearing 31, 32, and passes around adjusting-pulleys 38, 39 and an adjustable tension pulley r. The shaft 21 is provided with a hand brake 24 and drives a revolution counter 70 showing the number of turns wound on the spool.
