Abstract: 666,292. Winding yam. ABBOTT MACHINE CO. May 23, 1949 [Aug. 17, 1948], No. 13690/49. Class 120(iii) A yarn winding machine including a plurality of winding units each adapted to wind yarn packages is combined with means for conveying the packages wound by the several units in a procession to a common point and mechanism for arranging the packages of such procession in rows upon individual package holders. In one modification, as applied to a winding machine wherein a number of winding units 15 travel around the machine, the wound packages are released from the winding centres by an abutment 31 to fall on to a plate 32 along which they are rolled by rods 36 on the winding units. The packages then roll into a pivotally-mounted cradle 40 attached by links 49, 52 to a crank disc 53, which is intermittently rotated, the cradle also having attached thereto a microswitch 57 and delivering each package into a carrier 41 of a series of carriers supported by an endless chain 59 intermittently advanced by a Geneva stop motion. The carriers 41, guided bv a curved bar 63, are disposed substantially horizontally as they receive their packages from the tiltable cradle 40 and then assume a generally vertical position before they deliver their packages, in say, groups of eight to the pins 12 of pin-boards 11 forwarded intermittently beneath the carriers 41 by frictional contact with endless chains 80. The packages are kept in their carriers during the change of position thereof by a curved plate 65 and when the carriers 41 are substantially in the vertical position, a tiltable gate 67 closes the mouths of, say, eight containers, the gate 67 being opened by a cam-like device operated by a onerevolution clutch 90 when eight packages have been fed into position. the one-revolution clutch device 90 is driven by a belt in synchronism with the travel of the winding units 15 and furnishes the power for driving the carriers 41 and other parts of the package arranging and delivering mechanism. The clutch 90 is latched by a member 98 which is lifted to release the shaft 115 for a single revolution when the switch 57 is made, thus energizing a solenoid 110, by a package entering and tilting the cradle 40. The crank disc 53 feeds the package in the cradle to a carrier and repeats the process until eight such carriers have been fed into position. The pinboards 11 are stacked horizontally between angle-pieces 140 above a gate mechanism and released one by one by a cam-operated elevator plate 146 raised and lowered through sprockets 152 and chain 151. Each pin board 11, upon release from the stack, moves with the chains 80 until it abuts the one being supplied with packages which is retained in position by hooks 82 which engage pins 12 and are released when a row of packages has been fed through the gate 67. A switch 160 opens if a pin board is not in position to receive discharged packages and stops the travel of the winding units 15. A manually operated starting switch 172 is fitted in the supply lines so that the machine can be run until a pin board comes into position to close the switch 160. The current supply 168 energizes the motor 171 which drives the chain 18 forwarding the winding units 15, and through a transformer 170 supplies the rails 20 and hence the individual winding unit motors 19. A further modification is described in which the several winding units are stationary, the wound packages therefrom being guided by shoots to a conveyer wherein they form a procession and are led to the carriers 41 operating as previously described.
