Abstract

A time delay combination lock having the usual combination mechanism including a stack of rotatable tumbler wheels journaled on a dial spindle by a driving cam, and a fence lever pivoted on a bolt to descend to a lower coupled position with the drive cam and retract the bolt along an unlocking path when the proper combination is dialed. A timing movement is provided having an intercoupling gear train including an input gear rearwardly adjacent the driving cam for winding the main spring to woundup condition upon rotation of the dial and driving cam through a predetermined arc. A pivoted blocking lever biased to a normal stop position is located in the unlocking path of part of the fence lever to bar unlocking movement of the fence lever in its lower coupled position, and the lock case has a fixed backup shoulder immediately adjacent the blocking lever to support the blocking lever against attempted forced displacement of the fence lever and bolt in a bolt unlocking direction. The intercoupling gear train permits multidirectional operation of the dial to dial the combination for a limited time dialing period following wind-up of the main spring, and a lever system is provided to displace the blocking lever to a release position for a later short time period after termination of the multidirectional dialing period to allow retraction of the bolt to unlocked condition. A formation on the input gear bars change key access to the combination change mechanism except at selected positions.
