ABSTRACT:
An adjustable depth gauge assembly for a key cutting device includes a rotatable gauge or cam member carried by a vertically and transversely movable key blank support that sequentially positions a key blank in selected cutting relationship to a cutting punch or die. The gauge or cam member includes a continuous uninterrupted cam surface which is sequentially engageable with a finger or pin disposed in the path of movement of the gauge member to selectively limit vertical movement of the key blank support. The gauge assembly also includes an indicator arm for rotating the gauge member to a desired position so that the depth of cuts in a key blank may be varied in accordance with a pre-established code pattern.
