Abstract
368,541. Obstructing keyholes. WINSTANLEY, H. M., The Cedars, Bray, Berkshire. March 26, 1931, No. 9235. [Class 44.] The withdrawal of a lock-key is prevented when a door 2 is moved from its fully closed position by a pivoted bar 5 which obstructs the keyhole either by itself, Fig. 1, or by a pivoted member 9, Fig. 2. A projection 12 on the striking plate holds the member 9 from the keyhole when the door is closed.
