This is a mechanism to stamp Hallmarks on wire, to identify the
alloy of the wire. ie 14 K Gold, or Sterling 925 etc.
The pancake air cylinder at top provides the downward pressure, and it has very little stroke, 1/2" or less. The air-pressure is controlled by a limit valve, going through a 4-way valve for the pulsations required. The force is controlled by the two hardened flat plates in the housing at bottom, the reverse image of the lettering is engraved into one of the plates and a ground groove the thickness of the wire in the other to provide for centering of the wire to the stamp engraving.
