ABSTRACT:
The invention disclosed in the application is a time lock for bank vault doors and the like having a plurality of timer units of the settable dial type with a clockwork mechanism which includes a slip clutch in the gear train which permits the main winding stem to be rotated in an unwinding direction to move the dial in a descending time direction if it has been overdriven to a higher time setting than desired, and which includes a kicker arm mechanism to be abruptly kicked by spring force against a carrier assembly for the time lock unit to shift the carrier to release position when the dial reaches zero time.
