Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
128 words
Engraving apparatus which comprises means supporting a workpiece for motion in mutuallyperpendicular X and Y directions along its surface, an engraving head supported for motion in a Z direction substantially perpendicular to the surface of the workpiece, means including a pantograph responsive to variations in the X and Y coordinates of a pattern for shifting the X and Y disposition of the workpiece, said supporting means for the workpiece including a chuck mounted for rotation and adapted to releasably mount the workpiece, said supporting means including a carriage mounting said chuck for rotational motion and itself mounted for slidable motion in an X direction in response to actuation of said pantograph means, and means mounting said chuck on said carriage for angular adjustment of its axis of rotation.
