## Abstract

A hand-held guide 50 for manually positioning a workpiece 58 between the anvil rib 25 and tool 9 of a hot die stamping press. A groove completed by interchangable cover plates 60, 70, 70' attached at one end of the guide conforms to a cross-sectional dimension common to similar workpieces and, with a force fit, retentively holds each of the workpieces.

## Claims

### Claim 1

A fixture for holding a flat, stiff workpiece for contact with a stamp head, comprising:
a unitary member having a generally elongate shape providing a hand graspable section (50) and a planar, distal terminal section (51);
a narrow and elongate slot (54) formed in said planar, distal terminal section having a bottom surface, a rear surface, and at least one side wall said slot being open to the end and top surfaces of said terminal section; and
an elongate cover (60) having a flat underside detachably secured to said top surface of said terminal section and forming with said bottom surface, rear surface and said side wall of said slot a continuous force-fit receptacle for a terminal segment of a flat workpiece having a thickness substantially equal to the separation between said underside of said cover and said bottom wall of said slot.

### Claim 2 (depends on 1)

The fixture of claim 1 wherein said unitary member includes a recessed portion (53) intermediate of said hand graspable section and said terminal section.

### Claim 3 (depends on 1)

The fixture of claim 1 wherein said rear surface of said slot has a passage (80) formed therethrough.
