ABSTRACT:
A combination lock having two or more disks and a cam which includes a drive pin for driving an adjacent disk which, in turn, drives the next disk. The disks have pins adapted to be received in apertures in two or more disks, known as wheel gates, the disks and the cam can be moved inwardly. In this position, a notch on the cam engages a nose on a drop lever which is in turn connected to the locking bolt. Rotation of the cam in one direction will then move the bolt to the unlocked position.
