Abstract
A machine for making identical tubular keys from a sample includes a decoder having a gage means mounted on the base of the machine for measuring the axial length of a bite in the sample. The decoder serves to position a first stop means for engagement by the blank to be cut so that the bite cut in the blank by a cutter will be of the same axial length as the bite in the sample. For proper positioning of the stop means, the decoder includes a rotatable cam disk having opposite edges shaped as inverted mirror images of each other. With this shape, the disk may be turned on a support until one of the edges engages the gage means. Once so positioned, the opposite edge of the disk locates the stop means for engagement by the blank at an axial position for cutting the same length of bite in the blank as the length of the bite in the sample being measured by the gage means. A lever mechanism connected with a key-carrying chuck mounted on the base is operable to move the chuck relative to the cutter in both axial and radial directions so that the bite to be cut in the blank can be cut with a single stroke of a lever within the mechanism.
