Abstract
A combination padlock has dial-driven rotary sleeves mounted within the lock casing on a longer leg of the padlock shackle. The sleeves have peripheral teeth with at least one tooth being omitted on each sleeve to define a bypass gap. To open the lock, the dials must be rotated so as to turn each of the bypass gaps into alignment with a respective blocking projection in the lock casing. To thwart any attempt to pick the lock, alternate teeth on each sleeve are shorter than the adjacent teeth whereby a detent-type feel may be produced when the sleeve is rotated, simulating the feel produced when the bypass gap is brought into line with the respective blocking projection.
