ABSTRACT:
A mechanism for moving a cross slide in a multiple-spindle automatic machine has a rotary face cam which is driven by a gear and is angularly adjustable with respect to the gear, a first lever which is pivotable on a first shaft parallel to the axis of the cam and which has a first arm carrying a roller follower for the cam and a second arm having a slot for a sliding block which is mounted on a pin-shaped carrier. The carrier extends through one or more slots of a second lever which is rigid with a second shaft, and the carrier can be fixed to the second shaft in a selected position by means of washers and nuts. The second shaft is rigid with a gear segment which meshes with a toothed rack affixed to and adjustable lengthwise of the slide. The first lever may be a bell crank lever or a straight two-armed lever, and the second lever may have a single arm with a single slot for the carrier of the sliding block or a bifurcated arm with two aligned slots for the carrier.
