Abstract: 727,291. Winding yarn &c. TAYLOR, W. P. March 17, 1953, No. 7408/53. Classes 120(2) and 120 (3). A machine for winding yarn &c., packages of the type set forth in Specification 727,290 comprises a rotary spindle, a reciprocable guide means for traversing yarn, &c., along the spindle, said guide means being slightly outof-plane with the spindle so as to lay successive coils side by side, and means controlled in synchronism with the spindle and guide to vary temporarily after periods corresponding to a substantial number of revolutions of the spindle and at the same angular position of the spindle with respect to the guide, the relative movement of spindle and guide to produce a wider spacing between certain coils, thereby leaving a hole through the package radially thereof. As shown, the machine is driven from a suitable power source M through a pulley 6 and a known speed control device 4 adjustable through a handle 8. On the output side of the device 4, a pulley 12 drives the spindle-supporting shaft 18 and a pulley 22 drives a variable speed device having coned pulleys 26 adjusted by a hand wheel 28. The device 26, through belt 30, gearing 34, and shafts 36 and 40 drives a toothed clutch member 50. The mating clutch part 52 also carries reversed teeth on its opposite face which may be brought into engagement with a toothed braking plate 70, the clutch part 52 being slidably keyed to a shaft 46 and movable to and fro by a lever 60 operated by solenoids 66, 68. The shaft 46 carries two heart cams 72, 74, (72 being for balancing purposes only), the cam 74, through rollers 76, reciprocating slides 78, 80 in guides 82. A clamp 83.on the slide 80 oscillates the slotted lever 86 about a bolt 90 adjustably fixed in a slot 92 in a guide member 94. The guide carriers rollers 96 through which the yarn, &c., guided by rollers 102, 104, 100, passes to the spindle 114 which is split diagonally and furnished with holding pins, the assembled parts being secured on the shaft 18 by a nut 110. The spindle-supporting shaft 18 carries a disc 118 furnished with two angularly-adjustable cam members 120, 122, held to the disc through bolt and slot connections. The cams 120, 122 operate rollers which control micro-switches 132, 134. Similarly, the traverse cam 74 is provided with an angularly-adjustable cam member 136 which has two upstanding portions, one of which may be removed, disposed 180 degrees apart about the shaft 46. These cams co-operate with a roller which controls a microswitch 144. The shaft 18 also carries, an insulating disc 146 provided with a ring of soft iron 148, while on the supporting bushing 20 is fixed a plate 150 having a stop 152 and a microswitch 154. Journaled on the plate 150 is a lever 156 having an aperture in which is slidably mounted a small timing solenoid 158 which co-operates with the ring 148 ; the stop 152 and a switch 154 are in the path of the lever 156. The switches 132, 134, 144 are in series with aholding solenoid 160 which is thus energised only when all three are closed, the switch 172 being normally closed. The clutch operating solenoid 68 is in parallel with the motor M circuit and is thus energised whenever the main switch 162 is closed. When the solenoid 160 is energised, switch 164 is opened to make circuit through the timer switch 154 and the brake solenoid 66. The solenoid 66 closes the switch 166 to shunt the switches 132, 134, 144 and energise the timer solenoid 158. If switch 172 is opened the machine winds the ordinary universal wind, while if switch 170 is closed, the switches 132, 134 are shunted so that adjustments may be made.
