ABSTRACT:
A code changing mechanism for padlocks of the type comprising code wheels and lock operating bushings releasably connected to the code wheels in which axial movement of the shaft disengages the bushings from the code wheels to permit changing of the code, and in which the long leg of the shackle has means for engaging the end of the shaft to move it axially to the disengaging position when the shackle is depressed into the body in an orientation other than the locking orientation. In one embodiment of the invention the shackle can be locked in the open position to prevent code changing without knowledge of the existing code.
