Title: Improvements in or relating to pattern controllers for knitting machines
IPC: D04B15/66
Filed: 1949-02-28
Abstract: 673,655. Pattern mechanism for circular knitting-machines. JACQUARD KNITTING MACHINE CO., Inc. Feb. 28, 1949 [Feb. 28, 1948], No. 5393/49. Class 74 (ii). In a mechanism for controlling the advance of pattern calling means, comprising a master pattern directing change calling patterns; the patterns are advanced through Geneva type mechanisms - without the use of ratchets. The embodiment described is applicable to a six-feed machine and comprises a continuously rotating shaft 1 having keyed thereon a slidable sleeve 8 carrying a cam 7 and Geneva wheel driving tooth 9. The tooth 9 constantly drives a Geneva wheel 13 rotatable on a hub 12 itself rotatable on a shaft 11. A cam-track 17 on the wheel 13 has rises 18 which oscillate an arm 38 to withdraw a pin 41 from and advance a pin 44 into the path of the cam 7. The pin 41, when advanced, serves to keep the sleeve 8 to the leftwhereby a Geneva wheel 20 secured to the hub 12, is kept locked by a portion 10. The advanced pin 44 slides the sleeve 8 to the right, whereby both wheels 13, 20 are driven by the tooth 9 for the period of the rise 18. A sprocket 22, coupled to the wheel 20, thus advances the master pattern chain 35, any rise 36 of which operates through levers 45, 49, 51, pins 54, 57 and a sleeve 58 actuated similarly to members 41, 44, 8, a Geneva wheel 66 coupled to sprockets 78 of the change calling pattern chains 83. The pattern chains 83 actuate feelers 85 and push-rods 94. The wheels 20 and 66 may be disconnected from the pattern sprockets by withdrawing spring-loaded pins 25, 74 when adjustment of timing is necessary.
