Abstract
A key duplicating apparatus is disclosed which includes a base and platform supporting a reciprocating carriage assembly and a pivotally mounted housing. The carriage assembly has a key securement means which secures a blank key and a template key in alignment for positioning, respectively, with a notch cutting means and a notch depth indicating means, so that a template key may be duplicated by cutting notches of a predetermined depth and position into the shank portion of the blank key. The duplicate key may be cut by use of the template key as a pattern, with a guide cam affixed to the indicating means aligned with a cutter wheel affixed to the notch cutting means. Alternatively, the guide cam may have indicia about its circumference, which may be used to "dial" and decode a manufacturer's code for the purpose of creating a duplicated key. As the guide cam is rotated, the invention may be used to cut a duplicate key from the notch pattern presented in the code.
