ABSTRACT:
A combination lock has a plurality of gated tumbler wheels mounted for rotation relative to a gate entering bar portion of a release lever, blocking a release movement of such lever until gate openings on the tumbler wheels are aligned to said bar and a tumbler locator and lever arm actuator member mounted for both axial and rotative movement relative the axis of rotation of the tumbler wheels. The member has a drive pin engaging, and successively releasable from, drive apertures divided in the tumbler wheels to allow rotation of the tumbler wheels upon rotation of the member and sequential release of located tumbler wheels upon an axial movement of said member relative to said tumbler wheels. A portion of the release lever rides upon a smooth cylindrical exterior surface of the member, preventing engagement of the lever associated bar with any of the tumbler wheels, and the gate openings, until the member has been moved axially into a tumbler wheel release location which aligns interengaging means between the member and the lever in order to operate the latter upon further rotation of the member. A dial assembly and means for selectively adjusting the axial position of the member are also provided.
