Abstract

684,525. Locks. ELORZA, B. Z. Nov. 6, 1950 [Nov. 8, 1949], No. 27070/50. Class 44 To prevent the door lock b and keeper plate a being forced apart to release the bolt d e.g. by a crow-bar there is provided a catch c pivoted inside the lock and adapted to turn, as the bolt is shot, to the position shown in Fig. 2 in which it embraces both plates and clamps them together. The catch may be arranged to swing back under gravity to the inoperative position when the bolt is retracted (the bolt d being normally mounted horizontally). Alternatively a spring may be provided to return the catch.
