Abstract

223,836. Chatwood Safe Co., Ltd., and Bruckshaw, H. S. May 30, 1924. Locks, preventing release by destruction; seal fastenings.-In a safe or strong-room door lock in which a blocking slide, controlled by locking mechanism, engages the bolt tail to lock the bolt, a spring plunger, normally held retracted by a projection on the lock cover-plate, is provided to retain the slide in its blocking position, without movement of the slide, if the cover plate is blown away in an attempt to burgle the lock. The slide e controlled by the locking mechanism f blocks the bolt, which slides in the casing at right-angles to it. A plunger c pressed outwards by a spring is normally held retracted by the projection b on the cover-plate a. If, in an attempt to force the lock by explosives, the cover-plate is blown away, the plunger shoots forward into the recess d in the slide and retains it in its operative position. A lead or similar seal h prevents access to the screw g so that the plunger cannot be retracted until the seal is removed.
