Abstract
Needle selecting device in a circular knitting machine of the type having oscillating needle pusher jacks. The selection is effected by engaging teeth of a toothed selection disk with corresponding pattern butts of respective needle pusher jacks. The jacks are moved into an inoperative position where the jacks are not raised and do not lift the overlying needles to a thread pick up position at a given feed. The toothed disk is rotated by a coaxial entraining disk at a rotational speed such as to achieve substantially a rolling action between the needle cylinder and toothed disk. The disk is angularly displaceable with respect to the entraining disk between an angular position corresponding to engagement and an angular position of no engagement. The angular displacement is ensured by a lever having a hooked end which can be controllably inserted between the teeth of the toothed disk for temporarily stopping the rotation of the toothed disk with respect to the entraining disk against the bias of an elastic member placed between the toothed disk and the entraining disk. The entraining disk has a plurality of peripheral bosses equal in number to the number of the teeth of the toothed disk and shaped to guide the hooked end to a position releasing the toothed disk. The hooked end is provided with discrete engagement surfaces for engagement respectively with the bosses and with the teeth of the toothed disk.
