Abstract

500,540. Revolving - barrel locks. ELZETT EISENWARENFABRIK AKT.- GES. Sept. 22, 1938, No. 27612. Convention date, Feb. 18. [Class 44] In a revolving-barrel lock operated from either side by an asymmetrical key so that at least. two tumbler pins co-operate with different key depressions when the key is reversed, some of the pins consist of more than two parts so as to be released by depressions of different depths. Where the bolt tongue lies between the tumblers, as, shown, there need be only one pin such as the second or third with more than two parts. With a three-part pin 1a .. 1c in engagement with a depression 9, part 1b rotates with the cylinder 5, but when it engages a depression 10 on reversing the key 4, part 1b is held stationary.
