ABSTRACT:
Cartridges each containing a different punch, stripper and die are moved automatically by a robot-like transfer mechanism between a punch press and a tool rack for storing several of the cartridges. The transfer mechamism is characterized by a hook-like hand having laterally spaced and laterally stationary hooks formed with notches which coact with pins on each cartridge to enable the hand to lift and carry the cartridge. Cam plates with cam surfaces are located adjacent the notches and cam against the pins to automatically shift the cartridge to a laterally centered position in the hand when the hand first lifts the cartridge.
