ABSTRACT:
A clamp for clamping a workpiece comprises a base member, a clamping member mounted on the base member for limited linear and rotational movement relative thereto and a drive member mounted on the base member for rotational movement relative thereto. First and second cam elements are provided on the drive member and the clamping member and arranged such that relative rotation of the drive member and the clamping member produces relative linear movement thereof. The clamp includes a lost motion mechanism whereby rotation of the drive member can produce limited rotational movement of the clamping member without causing linear movement thereof.
