ABSTRACT:
A transfer device for transferring workpieces progressively from station to station in a press by means of mechanical linkages actuated by the press ram. The linkages are uniquely configured and constructed to provide substantially unobstructed access to the stations. A clutch mechanism is provided that resiliently disconnects the linkages in the face of a predetermined resistance in order to prevent damage in the event of the jamming of a workpiece. At least one of the linkages is constructed as a unitized assembly for ease of installation. Brake means and lift and carry features may also be included in the transfer device.
