Abstract

205,943. Lawrence, E. M., and Richardson, G. T. Aug. 23, 1922. Striking plates and staples for locks and latches.-A spring plate is mounted in the crack between the door and door-jam, to prevent the insertion of a gimlet or like tool from the outside of the door, into the crack to force back the latch-bolt. The plate 17, may be made of springy metal, or may be spring-controlled and is mounted adjacent to the lug L of the striking plate 15 which enters the crack 12 across which it extends to engage the edge of the door 10 when the door is closed. The edge 20 of the plate 17 is sharp so that it makes a close contact with the door-edge. A gimlet or like tool inserted through the material of the door-jam 11 to enter the crack 12, is deflected by the plate 17 and cannot force back the latch-bolt 14 of the lock 13. The plate 17 may be mounted on the lug L of the striking-plate as shown in Fig. 1, or between it and the door-jam and may be bent so as to allow the lug L to be fitted flush with the door-jam. The plate 17 may be fitted to the edge of the door and may be secured by screws passing through one elongated slot 18 or a pair of elongated slots 21, to allow of vertical adjustability, or it may be secured by two plain screw holes 22.
