Opinion of the Court. "The combination-lock may be punched from place, but the clock-lock, being separate and independent from it, and having no opening through the door, cannot be affected. It is therefore superior to a lock which has the time-movement combined directly with the combination-lock, both forming one lock, in which case any violence to the lock-work disarranges the clock. nation-lock, the time-lock will remain intact, and cannot be opened by the burglars or the officer in charge of the combination. Such results cannot be accomplished by a time-lock alone, because when it releases its bolt-work the safe or vaultdoor is absolutely unlocked, and no lock present for use during the day; nor by two or more combination-locks together, because the holders of the combinations may be taken to the bank and forced to open the locks. Neither can tàmpering with the combinationlock affect the time-lock. "The combination-lock may be punched from its position by burglars; but then the timelock, being separate and independent from it, cannot be affected or disturbed, because there is no opening through the door by which it can be reached. It is therefore superior to a lock which has the time-movement combined directly with the combination - lock, both An- forming one lock, in which case any violence to the lockwork disarranges the timemovement. other advantage of this invention is the capability of the separate locks of being applied on different parts of the door indifferently. The bolt-work on different doors is frequently "Another advantage of my invention is the capability of the separate locks being ap Opinion of the Court. such that the two locks cannot be applied together. The clock-lock in such case may be. attached at the most convenient location, as before described. It can also be applied with facility on old safes having the combination or key-lock already on, thus securing the advantage of a clock-lock and combination-lock without the necessity of removing the old lock and substituting a new one having a time-movement combined directly with the lock. "I do not claim, broadly, a clock-lock; nor do I claim two or more combination-locks combined with the door-bolt; but "I claim "1. The combination with a door-bolt, E, of a clock-lock, B, and a combination or keylock, A, applied independently on a safe, vault, or other door, so as to rest against or connect with said door-bolt, and plied on different parts of the safe or vault-door, with espect to the bolt-work, indifferently. "The bolt-work on different safe or vault-doors is frequently such that the time-lock and the combination or key-lock cannot be applied together; but in such case the time-lock may be attached at the most convenient location, as no opening through the door is requisite. "The time-lock can be applied with ease and facility to the doors of old safes or vaults having the combination or key-lock already thereon, thus securing the advantage of a time-lock and a combination or key-lock without the necessity of removing the old lock. "I do not claim, broadly, a time-lock of any peculiar construction; nor do I claim two or more combination-locks combined with the bolt-work of a safe or vault-door, as such are old and well known. "What I claim, and desire to secure by letters-patent, is "1. The combination, with the bolt-work of a safe or vaultdoor of a time-lock and a combination or key-lock, both applied independently on a safe, vault, or other door, so as to rest against or connect with Opinion of the Court. out of coincidence with the tongue of the door-bolt, whereby the door-bolt may be retained in the unlocked position for shutting the door and prevented from being withdrawn, when locked, until both locks have been unlocked." cally brought into and out of coincidence with the tongue of the bolt-work, whereby the bolt-work may be retained in the unlocked position for shutting the door, and prevented from being retracted when locked, until both locks have been unlocked. "3. The combination, with the bolt-work of a safe or vaultdoor, of a combination or keylock controllable mechanically from the exterior of said door, with a time-lock having a lockbolt or obstruction for locking and unlocking controllable from the interior of the door, both of said locks being arranged so as to rest against or connect with the bolt-work, the time-lock being automatically unlocked by the operation of the time-movement, both of said locks being independent of each other, and arranged to control the locking and unlocking of the bolt-work, so that said safe or vault-door cannot be opened when locked until both of said locks have been unlocked or have released their dogging action, to enable the door to be opened, substantially as described."
