Abstract
A combination locking arrangement includes a locking member, a locking lever connected to the locking member; and at least first and second tumbler discs rotatable about a tumbler disc axis. When each of the tumbler discs is rotated to an unlocking orientation, the locking lever engages aligned recesses in the tumbler discs, such that further rotation of the tumbler discs moves the locking member from the locking position to the releasing position. A dial is rotatable about the tumbler disc axis for selective rotation of the tumbler discs, and includes a drive portion rotationally secured in interlocking engagement with the first tumbler disc in one of a plurality of code selecting orientations. The locking lever includes a disc securing portion positioned to prevent axial disengagement of the first tumbler disc from the dial drive portion when the locking lever is engaged with the aligned recesses in the tumbler discs.
