Abstract (en)
[origin: US4420955A] A permutation lock wherein a locking bolt is reciprocable in a housing between extended and retracted position. The housing contains a set of coaxial tumblers rotatable by a cam having a lobe which can move the bolt to extended position through the medium of a coupling lever which is pivotally connected with the bolt. The coupling lever can be pivoted to an operative position, in which it extends into the path of movement of the lobe on the cam, only when at least one of the tumblers is moved from a predetermined position in which a notch in its peripheral surface is out of alignment with similar notches in the peripheral surfaces of the other tumblers. The bolt is movable to the retracted position by a locating lever which is pivoted to the bolt and has a pallet receivable in a recess of the lobe only when all of the notches are aligned with each other so that they can receive a finger which is provided on the locating lever and extends in parallelism with the common axis of the tumblers.
