ABSTRACT:
Apparatus for making a duplicate key when an original key is unavailable wherein the notches in the blade of the key correspond to predetermined coded depth and spacing information. An index card having indexes thereon corresponding to predetermined coded depth and spacing information is inserted into a housing and a key having a blank blade is inserted into a key holder where it is held in a series of predetermined positions relative to a key nipping tool and corresponding to the coded depth and spacing information on the index card. Key blank positioning is indicated by a pair of pointers having arcuate movement corresponding to the coded indicia on the index card. The key blank is positioned, in accordance with the coded indicia on the index card, by linear movement of a key carrying carriage in both lateral and longitudinal directions relative to the key nipping tool, with such lateral and longitudinal movement corresponding to the depth and spacing therebetween of notches placed on the key blade and also corresponding to the arcuate movement of the pointers. Notches are placed in the key blade by depressing a handle which rotates a rocker assembly which in turn actuates a slide bar that draws the nipping tool down to engage the key blade. Cutting is facilitated by a ball and spring shock absorbing assembly located under the key carrying carriage which assembly also facilitates smooth movement of the carriage.
