Abstract
A pattern control mechanism for embroidering machines of the type which use punched tape and a gear-type analog computer with input cam slides for the generation of pattern movements in a large number of different magnitudes, the improvement relating to the cam slide driving mechanism, where pivotable horizontal slide pushers which are attached to the cam slides are selected vertically by transversely moving selector bars whose position is determined by feeler needles of the punched tape sensing device, and where the raised non-selected slide pushers remain back, while the lowered selected ones are engaged by a reciprocating pusher drive bar. The selector bars, which execute a vertical approach motion, have selector teeth which prevent the simultaneous drive engagement of both cam slides.
