Abstract
A key duplicating machine which automatically liens the original and blank keys, clamping the keys in alignment with the appropriate clamping pressure, cuts double-sided keys in a single pass, prevents operation of the machine without the presence of the original and blank keys in the machine and which is capable of accepting virtually any type of key shape for duplication. The invention includes a single-sided key duplicating module having a motor driven cutter wheel which is slidably mounted on a travel table that, in turn, is slidably mounted on a base plate. The travel table includes a motor driven stacked cam assembly which engages fixed cam followers in the base plate, so when rotated, the cam assembly, travel table and cutter wheels are moved first in a cutting pass, then in a return pass with respect to the original and blank keys. The cam assembly also includes a cam follower which displaces the cutting wheel sidewardly away from the blank key on the return pass. The original and blank keys are pressed against alignment surfaces by springs prior to clamping, and the springs are displaced away from the keys to provide clearance for the cutter wheel during cutting.
