Abstract

A jacquard pattern control mechanism for a circular knitting machine is provided in which a plurality of rocker bar supporting members are each slidable in one of the grooves along which one of the knitting elements move, a plurality of elongate rocker bars are pivotally mounted on one of unsaid plurality of rocker bar supporting members for movement about a medial pivot, the opposite end portions of the rocker bars being selectively movable between operative and inoperative positions and having magnetically attractable sections thereon, magnet attracting devices are operatively associated with the opposite end portions of the elongate rocker bars for selectively attracting one of the magnetically attractable sections at opposite ends of the rocker bars to pivot the rocker bars and selectively move one of the opposite end portions thereof to the other operative position and the other opposite end portion thereof to the inoperative position, the magnetic attracting devices comprising a permanent magnet and a pair of electromagnets disposed on opposite sides of the permanent magnet and connected in series, the permanent magnet having an extension extending outwardly towards the rocker bars and having a pair of wing portions extending outwardly from the center portion of the extension, generally parallel to the rocker bar supporting members and having outer sections disposed in attractable relation to the magnetically attractable sections at opposite ends of the rocker bars.
