Abstract: 416,453. Cop-winding machines. LAMBERT, O., 6, Cauwerberg, Tamise, Belgium. Sept. 28, 1933, No. 26698. [Class 120 (ii).] In a cop-winding machine of the kind in which the cop spindle 32, Fig. 4, is rotatable with and slides through a driving member 35 rotated by toothed gearing and is controlled by a stopmotion operating on reduction of the yarn tension and on attainment of the desired length of cop, and in which the cop spindle is associated with a traversing thread-guide 27, Fig. 2, an individual gear unit is provided for each spindle comprising toothed gearing 7, 34 for driving the spindle and fast and loose pulleys associated therewith and individual to the toothed gearing, and an individual belt or band drive 8<a> to each pair of fast and loose pulleys. The belt or band drive is transmitted to the spindle through gearing 7, 34 without the use of a clutch, thus providing a progressive start to the spindle without shock. Each thread guide is traversed by an eccentric 11 driven by the gear unit, and stop mechanism is provided for each spindle for simultaneously arresting the drive through the gearing unit to both the spindle 32 and the traverse mechanism 25, 27. The fast and loose pulleys 8, 19 and the eccentric arm 11 are carried respectively on the opposite sides of the spindle box 1, the shaft 2 and the loose pulley 19 running in ball bearings 3, 18, Fig. 1. The thread guide 27 works in a slotted bracket 29 supporting the cup 28 and is pivoted on a spring tongue 26 carried by the end of a lever 25 which slides in the block 15 and is pivoted at 23 on an adjustable bracket 20. The spindle 32 is carried by a holder 40 pivoted on a pin 39 secured to a bracket 38 slidable on a bar 37 which extends vertically from the box 1. A cop-forming cap 44<a>, against which the cop is built, engages over the lower end of the spindle holder 40. The top of the bar 37 is secured to a rail 49 to which is also secured a slotted holder 52 freely engaging a stop-rod 53. A belt-shifting rod 54 extends through the box 1 and is provided with a thumb piece 55 on its front end, the other end being bent at right angles and engaging the slotted end of a belt-fork 56 fixed on a slidably mounted rod 58. The belt 8<a> is held on the loose pulley 19 by a spring. When the thumb piece 55 is depressed the belt 8<a> is shifted on to the driving pulley 8. A lever 61 pivoted at 60 is provided with an adjustable bevelled latch 62 adapted to retain the thumb piece 55 in the depressed position and has a tubular extension to receive a pin 63 secured to the lower end of the stop-rod 53. The rod 53 carries a curved stop 64 which contacts with the pin 39 when the spindle 32 has been raised with the cop to the height corresponding to the finished cop. The rod 53 is thus forced back and causes the latch 62 to release the thumb piece 55, the spring then moving the belt 8<a> on to the loose pulley 19 and stopping the rotation of the spindle 32 and the traverse of the guide 27. The finished cop is removed by lifting the spindle holder 40 until a catch 45 on the bracket 38 engages a pin 47 on the upper end of the bar 37 to hold the bracket 38 with the spindle 32 clear of the cup 28. The spindle holder 40 can then be turned on the pivot 39 to remove the cop. The bracket 38 may be weighted if necessary. The broken-end stopmotion comprises a bowl 67<a> carried by a pivoted lever 67 having an arm 67b connected to a rod 68 slidably engaging over the pin 63. The yarn Y passes over the bowl 67<a> and if the yarn breaks or fails the spring 70 moves the rod 68 to the dotted position, displacing the pin 63 and stopping the machine.
