ABSTRACT:
An apparatus for producing copies of keys comprises a pair of vertically spaced clamps, one of which clamps the key to be duplicated and the other of which clamps the key blank to be cut. A movable carriage carries, in vertically spaced relationship, a stylus for tracing the contours of the key being duplicated and a driven cutter for cutting the key blank. A drive mechanism drives the carriage through a working stroke carrying the stylus and cutter, respectively, along the length of the key and key blank so as to cut the key blank into the shape of the key, and a cam arrangement thereafter displaces the carriage laterally so that the drive mechanism returns the carriage through a return stroke while maintaining the stylus and cutter out of contact with the keys.
