Abstract
A combination lock for bank vaults, safes and the like, including a pack of peripherally gated tumbler wheels loosely journaled for rotation on a tumbler post about a common axis in the lock case, a peripherally gated rotatable driving cam positioned by a manually operable dial and knob member to angularly adjust the tumbler wheels through a lost motion coupling to an opening combination for the lock, and a fence lever having a pivot connection at one end to a slidable bolt for movement arcuately between raised and lowered positions relative to the peripheries of the driving cam and tumblers. The fence lever has an upwardly arching body and a fence portion defining a foot formation projecting from the arched portion having a downwardly facing recess spanning most of its lower end portion and an elongated unitary contact bar member pivotally seated therein to normally bear on the driving cam periphery.
