Abstract
516,692. Sliding bolts and striking plates. ARMSTRONG, F. G. G. July 5, 1938, No, 19866. Addition to 482,364. [Class 44] The trip member 29, 30 engaging the notch 28 in the bolt 22 of the parent Specification is pivoted on that end 32 of the lock casing through which the bolt extends, and has a projection 33 which, when the door is closed, engages a wall 37 on the striking plate 36 and turns the trip member out of engagement with the bolt, so that the latter can be shot by its spring 26. A safety catch 39 actuated by a spring 40 engages behind a shoulder 35 on the striking plate before the door is fully closed, and prevents reopening of the door. The trip member 30 is held in bolt-engaging position by a spring 42.
