Claim 1
Independent Claim
265 words
An apparatus for embossing an imprint in a workpiece, the apparatus comprising: a rigid frame having a front end to one side of the workpiece to be embossed and a rear end to the other side thereof; means supporting at least the front end of the frame for movement relative to the workpiece in a longitudinal direction which extends across the workpiece and between the front and rear frame ends; an anvil on the front frame end and engageable with the one side of the workpiece; a tool support; means supporting the tool support on the frame for longitudinal movement relative to same and to the workpiece; a tool wheel rotatable on the tool support about a transverse tool axis generally perpendicular to the longitudinal direction and having a periphery carrying a plurality of tools spaced angularly about the tool axis, the wheel being angularly displaceable through a plurality of respective positions in each of which a respective one of the tools longitudinally forwardly confronts the other side of the workpiece in line longitudinally with the anvil; drive means on the tool support for rotating the tool wheel about the tool axis through the respective positions; and actuator means engaged backward against the rear end of the frame and engageable forwardly with the tool wheel at a location thereon diametrally relative to the tool axis opposite the tool confronting the workpiece, whereby the actuator means can expand longitudinally and pull the anvil back into engagement with the one side of the workpiece while pushing the wheel into engagement with the other side of the workpiece.
Claim 2
Independent Claim
