ABSTRACT:
A clamp to hold a workpiece on a machine work table provides a body carrying an elongate fastening beam extending therefrom for adjustable positioning over a portion of the workpiece. The beam pivotally carries a vertically depending holder arm in a first outer end portion and is carried at a second inner end in the clamp body structure for both axial and vertically angulated motion. The clamp body is releasably fastenable to the machine work table and defines a vertically extending channel to receive the fastening beam. A vertically adjustable support pin extends horizontally through the channel to support the second beam end and the body carries a fastening screw depending into the channel spacedly distant toward the first support beam end to contact the medial portion of the support beam and create downward force thereon to hold a workpiece supported on the machine work table.
