ABSTRACT:
A loader assembly for use with a machine tool comprising a drum-shaped carrier including a plurality of equispaced workpiece receiving recesses, means for selectively indexing the drum-shaped carrier, a workloading chute including means for sequentially advancing a plurality of workpieces to a selected one of the plurality of carrier recesses, and a loader mechanism including a housing supporting a pair of rams having gripper means at one end thereof, means for selectively displacing the rams intermediate retracted and advanced positions, the rams being selectively angularly related so that the center points of the gripper elements coincide at the advanced ram positions, and means for selectively displacing the gripper elements intermediate open and gripping positions, and means for selectively pivotally displacing the housing from a first position, whereat the coincident center points coincide with the centerline of the stocks of the machine tool to a second position, whereat the coincident center points coincide with the center of a second one of the equispaced carrier recesses.
