<p>A combination lock, including a plurality of dials and associated sleeve means for each dial, has a plug member which is longitudinally movable to first and second positions and which is cooperable with the sleeve means for being locked in the first position when the dials are off combination. A manually operable latch member formed to engage a hasp is longitudinally movable from a latching position to an unlatching position only when the plug member is not locked in the first position. Longitudinally movable pullers are provided for moving the latch member from latching to unlatching position and from unlatching to latching position, respectively.</p> |
