Abstract

1343148 Barrel locks E EDELMANN & CO 19 April 1971 [25 Feb 1970] 22643/71 Heading E2A A barrel lock has only a single tumbler 26, this tumbler being elongated in the direction of the cylinder axis and having an internal profile which necessitates the correct key bitting 37 for its correct attitude for unlocking, Fig. 5. In use, the key enters a slot 32 in the tumbler, but if the key is incorrect, the tumbler will tilt (Fig. 6, not shown) and remain locked, the use of two springs 34 aiding this result. The barrel may have a spring-loaded key-hole shutter (48).
