ABSTRACT:
A combination lock of the dial and sleeve type has a scramble feature enabling a hasp to be engaged with a latch of the lock even when the dials and sleeves are not on-combination, by independent movement of the latch relative to manual actuating means of the lock. When the hasp is engaged, it supports the latch in a position in which the latch is adapted to engage a blocking element that prevents the latch from being moved out of its hasp-engaging position independently of the manual actuator. This arrangement effectively prevents the lock from being forced open when the hasp is engaged.
