ABSTRACT:
A double pin tumbler cylinder for a security lock in which a pin tumbler rotates in a cylinder housing. The cylinder housing is composed of an axial stack of discs punched from a sheet of chrome-nickel steel. The individual discs are soldered or welded together to constitute a rigid element. The discs have a tang portion in which an opening is made so that the assembled stack defines a channel for receiving a bar of chrome-nickel steel for additional reinforcement of the cylinder. The bar has an enlarged central portion with a threaded bore for receiving a locking screw.
