Jacquard-pattern arrangement for circular knitting machines

Claim 1

In a Jacquard-pattern arrangement for a circular knitting machine having one pattern drum per knitting system, said pattern drum being actuated in a stepwise manner by cam means mounted on the rotating needle cylinder of the circular knitting machine, the improvement comprising in combination, a plurality of rods removably mounted on said pattern drum, a plurality of actuating members juxtaposed with respect to each other disposed between said pattern drum and said needle cylinder and adopted to be actuated by said rods on said pattern drum to move into an operating position with respect to said needle cylinder, slidable bar means operatively mounted between said pattern drum and said needle cylinder and adapted to engage said plurality of juxtaposed actuating members and to move them out of engagement with said pattern drum and said rods mounted thereon, first cam means mounted on said needle cylinder and adapted to coact with said slidable bar means so as to cause the latter to disengage such actuating members from said pattern drum and said rods, said first cam means on said needle cylinder comprising a first cam which is mounted in front of said cam means for actuating in a stepwise manner the pattern drum with respect to the rotary movement of said needle cylinder, said slide slidable bar means being slidably mounted in a stationary portion of the circular knitting machine, said slidable bar means being radially movable with respect to said needle cylinder in said stationary portion of said circular knitting machine, said slidable bar means being provided with inclined bearing surfaces, and a bar movably mounted in said stationary portion of said circular knitting machine in parallel relationship to said bar means and having parallel inclined bearing surfaces which are adapted to radially move said slidable bar means when said bar is actuated by said first cam means.
