ABSTRACT:
An automatic contact ink stamping assembly characterized by repetitive movement of the die stamping surface between inverted positions defining an ink supply and a printing position. The apparatus is characterized by a stamping die assembly pivotally mounted to a carrier block reciprocally driven by a piston and cylinder assembly between the ink supply and printing position. The die assembly is provided with an upstanding ear having a cam surface which engages a rotatably mounted wheel in a manner to cause the die assembly to pivot 180 degrees responsive to the stroke of the piston and to align the die stamping surface in an accurate position perpendicular to the axis of said piston in both the ink supply and printing position.
