ABSTRACT:
A combination lock having setting discs which are arranged alongside of each other on a shaft, are turnable independently of each other and extend through slots in a front plate of a lock case, having locking sleeves associated with the setting discs, seated on the shaft, in spring-biased coupling engagement with the setting discs and formed on their periphery with depressions which, when the combination number is correctly set are located in a position opposite projections, and having an actuating handle arranged on the front plate, which handle can be displaced longitudinally from its basic position in order to release a hasp which extends into inside of the lock through an opening in the front plate and cooperates with a latch member, the actuating handle also serving to displace the locking sleeves out of their position of coupling engagement with the setting discs. The actuating handle can be displaced from its basic position in a direction opposite the direction of opening of the lock, and thereby pushes the locking sleeves out of their position of engagement.
