Abstract

A pattern control mechanism for a circular knitting machine with a rotating needle carrying cylinder, in which the needles are controlled at a pattern position by means of a plurality of electromagnetically controlled pattern devices, each needle being provided with an associated needle jack having control feet which follow each other in sequence in a stepwise manner, the needle jacks being slidable in the needle cylinder and being selectively swingable at the pattern selection point all of the needle jacks with their control feet are carried past a ramp-like cam which swings the needle jacks into a first position, in which they cooperate with their jack-advancing cam. A plurality of radially inwardly yieldably biased slide members are provided for swinging the respective jacks into a second position wherein they do not cooperate with such cam. Every slide means is provided with a magnetic holding mechanism which retains the respective slide means in an outer, retracted position, the returning force which opposes the magnets being less than the holding strength of the magnets. The respective slide members are retracted by magnet slide retracting feet mounted on the cylinder so as to retract the magnet armature into proximity with the pole piece of the magnet. If the magnet is then energized by a pattern control mechanism, the slide members remains retracted and thus the respective needle jack remains swung outwardly in operative position. If the magnet is not energized, the needle jack is swung inwardly into inoperative position by the slide members.
