Abstract

638,764. Permutation locks. LASSMAN & CO., Ltd., FREEDENBERG, D., and LASSMAN, S. Nov. 13, 1947, No. 30205. [Class 44] In a permutation lock of the kind having a sliding bolt with a number of indicia-bearing rings rotatably supported thereon, the bolt 10 is mounted in a body 1 having bored jaws 3, 4, and has pegs 16 to co-operate with rings 11 which fill the space between jaws 3 and 4; each ring has a gate in its bore for free passage of the pegs 16, and the bolt is urged to unlocked position by a spring 22 and prevented from rotation by a pin 26 engaging in a slot 25 in the bolt. The rings are cut away on each side to form annular grooves in which the pegs 16 work, and click producing recesses 14, Fig. 3, are formed in the side of the annular spaces, as described in Specification 605,018.
