Abstract: 327,199. India. Rubber, Gutta Percha & Telegraph Works Co., Ltd., and Wright, T. H. Jan. 3, 1929. Winding-machines; tension arrangements.-In apparatus for winding cotton threads or cords, metal wires or other filaments into coils or loops and of the type wherein the filament is wound around a former e.g. spaced studs, by a winding member, means are provided whereby on completion of one winding the wound former is automatically moved out of the winding position and replaced by another former without stopping the rotation of the winding device. A number of formers consisting of pairs of studs 54, 55, Figs. 1, 2 and 4, are arranged circularly on a carrierplate 50 mounted on a shaft 49 the carrier-plate being movable towards and away from the winding-member 5 and actuated so that on completion of one winding the plate 50 is moved out of the path of the winding-member 5 then rotated to bring an empty former into the winding position and finally moved back into its correct position relatively to the member 5. The former studs 54, 55 are respectively arranged on a block 52 and on a slide 53, each block 52 being adjustable in a radial slot 51, Fig. 4, and each stud 55 adjustable in a slot 56 formed in the slide 53. The coil is wound in grooves 57 formed in the studs 54, 55. A stud 58 projects rearwardly from each slide 53 and engages a cam-groove 59 in a plate 60 whereby on rotation of the carrier-plate 50 the slide 53 is moved radially from the setting when winding (positions A, A<1>, A<2>, Fig. 4) to the setting when doffing (positions B-C). In the winding position A the studs are the maximum distance apart and are equally spaced about the axis of the shaft 1, Fig. 2, while the grooves 57 are in the same plane as the tip 7 of the guide 5. The filament passes from a braked supply spool 17 round a drum 30 through a guide 14 and the hollow shaft 1 to the winding-member 5. The drum 30 is mounted between the upper ends of arms 27, 28 pivoted to a base 29 and is braked by a band 32 secured to an elastic member 34. A forked member 39, secured to a tension-strip 44 and a weighted cord 40, is attached to the upper ends of the arms 27, 28. During winding the arms 27, 28 are drawn forwardly towards the winding device. When the winding is stopped and the carrier is moved back the slack thread formed at the member 5 is taken up by the arms 27, 28 moving back under the pull of the members 43, 44, the movements being limited by adjustable stops 37, 38. The shaft 49 is moved axially out of the winding position against a spring 65 by a pivoted lever 63 the upper forked end of which embraces a collar 62 while the lower end bears against a face-cam 67. The shaft of the cam 67 is driven from the shaft 12 through gearing 74, 73, 70, 69 and a projection 75 on the cam 67 is adpted to rock the lever 63 and move the plate 50 back from the winding position, whereupon a Geneva stop mechanism 76 on the shaft 49 moves the plate 50 angularly through 60‹ to bring a fresh former into the position A. The plate 50 then moves forward into correct relation with the member 5. The apparatus is particularly adapted for winding loops of thread for use as reinforcement of the flexible couplings for transmission mechanisms described in Specification 321,999, [Class 80 (ii), Gearing, Variablespeed &c.]. The Provisional Specification describes a ratchet-and-pawl gear instead of a Geneva stop mechanism for controlling the angular movement of the carrier 50.
