Improvements in time locks for use in safes, vaults, or the like wherein the lock includes a clockwork mechanism which can be preset to a time until which the safe or vault cannot be opened. The improvements include improved means for bypassing the clockwork mechanism should one be locked inside the safe or vault on which the lock is installed. An improved simplified housing is provided for the time lock so that the entire lock need not be disassembled if there is a malfunction of the clockwork mechanism. Improved viewing means for the time lock are provided so that the face of the clockwork mechanism can be viewed from a convenient location above and at an angle to the face of the clockwork mechanism. An anti-tampering mechanism prevents the locking bolt from being released even if the device in which the lock is installed is dropped or vibrated. Finally, various other improvements are presented in other parts of the lock, such as the release lever assembly for releasing the locking bolt.
