Device for use in reproducing characters on cylindrical surfaces
Abstract
Abstract DEVICE FOR ATTACHMENT TO OR INCORPORATION IN ENGRAVING MACHINES AND THE LIKE, PARTICULARLY THOSE WHICH UTILIZE A FLAT MASTER PATTERN TO GUIDE A CUTTER, SCRIBER, OR OTHER TOOL FOR REPRODUCTION. ENABLES REPRODUCING WITHOUT MAJOR ALTERATIONS OR ADJUSTMENT TO MACHINE. WORKHOLDER CARRIAGE, MOVABLE LATERALLY AND HAVING A ROTATABLE CHUCK FOR GRASPING CYLINDRICAL WORKPIECE, IS LINKED TO CUTTER OR REPRODUCER TO MAINTAIN WORKPIECE IN ALIGNMENT THEREWITH. WIRE WRAPPED AROUND WORKPIECE AND ANCHORED TO STATIONARY BRACKETS CAUSES ROTATION OF WORKPIECE SURFACE EQUAL IN MAGNITUDE TO LATERAL MOVEMENTS OF CUTTER AND IN OPPOSITE DIRECTION THERETO. LINKAGE PERMITS LONGITUDINAL MOVEMENT OF CUTTER WITHOUT MOVING OR ROTATING WORKPIECE. COMBINED LATERAL AND LONGITUDINAL MOVEMENTS OF CUTTER RESULTING FROM TRACING CHARACTER PATTERNS ARE RESOLVED INTO DESIRED TRANSLATION AND ROTATION OF WORKPIECE SURFACE TO PRODUCE FAITHFUL REPRODUCTION OF MASTER PATTERN.
