ABSTRACT:
A workpiece carrier comprises a circular plate formed with teeth and interchangeably mounted for rotation by an arm longitudinally movable parallel to the plane of the plate. The arm can also rotate about the center of the plate. The arm has at least one pin adjustably fixed relative to the arm and arranged to cooperate alternately with one of the sides of opposite teeth, which side is oblique with respect to the trajectory of the arm. Longitudinal movement of the arm in either direction is effected by hydraulic means, connected with the arm through passage means suitably permitting the rotating of the arm. The longitudinal movement causes the plate to pivot by one step. At the end of the longitudinal travel of the arm, in either direction, the pin is located in the base of the gap between two teeth.
