ABSTRACT:
An adaptor for converting a conventional straight cut key duplicator into one capable of executing both straight and angular cuts. The angular cuts are necessary in duplicating MEDECO and EMHART type keys. The adaptor mounts to the vise grips of a conventional machine. It comprises a back plate and a front plate that is pivotally mounted to the back plate. A key vise is mounted to the front plate and is adjustable by means of an adjustment screw and a fine adjustment collar. The pivoting motion of the front plate allows for the angular cuts to be made on a key held in the adaptor. A set screw that mates with a plurality of apertures on the back plate holds the front plate in position at the desired angle.
