Transfer feed mechanism for power presses

A transfer feed mechanism for use in combination with a power press, said mechanism comprising the combination of

• multiple finger units for moving successive workpieces along a plurality of different axes so as to transfer the workpieces to desired work stations in desired positions and attitudes,
• a plurality of cams driven in synchronism with said power press for controlling the movement of said finger units along said plurality of axes,
• a plurality of rocker arms having cam followers riding on said cams, each of said rocker arms including a slidable adjustment mechanism for adjusting the point of connection of coupling means to any point within a predetermined range and thereby providing a range of adjustment for the length of the stroke of said finger units effected by movement of the rocker arm, said coupling means connecting each of said rocker arms to said finger units for effecting movement of said finger units along different axes in response to the movement of different ones of said cam followers,
• said slidable adjustment mechanism including,
• a hinged connector assembly coupled to said finger units,
• a hollow elongated member into which a portion of said hinged connector assembly transversely extends for longitudinal translation along said elongated member,
• a threaded member rotatably mounted in said hollow elongated member and coupled to said hinged connector assembly such that rotation of said threaded member positions said hinged connector assembly within a predetermined range,
• sensing means for determining the relative position of said hinged connector assembly within said predetermined range, and
• drive means for rotating said threaded member and moving said hinged connector assembly along said hollow elongated member into position to activate said sensing means.
