Abstract
Abstract The invention relates to patterning mechanisms for modified knitting machines. It particularly relates to patterning mechanisms in the form in which the needles are lifted by jacks having lifting butts movable between a position for engagement with a lifting cam at each feed station and a position for missing the lifting cams, the lifting butts being moved to cammissing position by rocking pressers cammed outwardly on approach to each feed station, to cause retraction of the associated jack, and the rocking pressers having, or being associated with, patterning butts which cooperate with selectors which either miss the patterning butts to retain the lifting butts in cam-missing position, or strike the patterning butts to rock the pressers to cause return of the lifting butts to the lifting cam engaging position. According to the invention, the action to operate the pressers to move the lifting butts to cam-engaging position comprises a first motion in one direction parallel with the needles, and a second motion perpendicular to the needles to complete the operation of the pressers, one of said two motions being applied to the pattern butts by the selectors, and the other being applied to the pressers by a formation fixed relative to the lifting cam.
