ABSTRACT:
A key cutting machine formed of a non-movable, horizontal shaft and an L-shaped lever centrally journalled upon the shaft for sliding and pivoting movement. A vise mounted upon the end of the horizontal part of the lever holds a key blank. A stylus mounted upon the vertical end of the lever contacts and moves upon a guide surface. This causes the lever to pivot, to conform to the shape of the guide surface, as it moves in the direction of the shaft. A cutter blade mounted above the vise engages and cuts the blank in accordance with the lever movement. The guide surface is formed by a series of disks which are axially aligned about a horizontal axis that is parallel to the shaft axis. The adjacent disks are arranged in face-to-face contact with each other and are relatively rotatable about their respective axes. The peripheral edge of each disk is provided with a series of steps, and corresponding indicia are provided remotely from the steps on the periphery of each disk so that the disks can each be rotated into pre-determined indicia positions, to thereby align pre-selected steps for contact by the stylus.
