ABSTRACT:
A transfer for hot forging machines or the like is disclosed. Such transfer includes a gripper support structure including a housing providing a longitudinal bore in which spaced cylindrical sleeve bearings are mounted. A gripper support provides the cylindrical portion journaled in the bearings for limited longitudinal movement. Mounted within an axial bore in the gripper support is a spring which resiliently urges the support in the direction of workpiece gripping. The support is provided with a longitudinal opening through which a key projects to prevent relative rotation between the housing and the support, and against which one end of the spring abuts. The housing provides substantially full enclosure of the working parts of the gripper to prevent damage by scale or the like.
