ABSTRACT:
A feed mechanism for transferring workpieces from a loading station to an unloading station comprises a carrier which is arranged to grip the workpieces during their transference and a frame relative to which the carrier is horizontally movable to effect the transference. The carrier is also movable vertically relative to the frame so that it can be raised or lowered vertically into engagement with each workpiece at the loading station. A piston and cylinder assembly is operable to raise and lower the carrier, and is controlled by a cam follower which is movable onto and off a raised portion of a movable cam. A further piston and cylinder assembly moves the cam relative to the follower when the carrier reaches either end of its horizontal travel, and the movement of the cam can be limited to control whether the carrier is raised or lowered or both raised and lowered at each end of its horizontal travel.
