  • Articulated arm transfer device
    Patent number: 4909701
    Abstract: In a material transfer device, an articulated arm assembly extends and retracts in a "froglike" motion to transfer an object between a plurality of locations. The articulated arm assembly is rotatable about a pivot point in a radial plane and can be raised or lowered in an axial direction to align the object with the intended destination. A greater degree of axial mobility may be provided, for example by a rotating lift screw. A vacuum chamber may be provided, with the arm assembly moving the object between locations in the chamber.
