The relocking of the lock therefore requires rewinding of the clock as a necessity. "On the back of the dialwheel H is a pin, r, Fig. 4, forming a stop. On the pallet 8, which engages with the scape-wheel t, is a pin, u, which projects out through a slot, v, of the stationary clock-frame. As soon as the dial-wheel has acted upon the lever m to unlock the lock the pin r of the dial-wheel strikes the pin u of the pallet and locks the latter in the scape-wheel, thereby stopping the clock. There is, therefore, no loss of motion, nor can the dial-wheel get out of position with respect to the pointer. for which it is designed to obstruct the bolt-work. Thus the resetting of the time-lock requires rewinding of the time mechanism as a necessity, and hence no danger of its being unlocked accidentally during the period of hours for which it is set. "The dial-wheel is turned back to set the time-lock by a key applied at the windingarbor o. "By the means above described I obviate a great objection to common clock-locks, which run on until they run down, thus subjecting the lock to the danger of a lock-out,' caused by neglect of winding. "By this means the timelock cannot be set without winding, for the pins n n, resting in contact with the arms of the yoke, it (the yoke) cannot be engaged with the lockbolt or obstruction until the dial-wheels have been moved back to set the lock, as before described.

If the holder of the combination is forced to open the combination-lock at night, the clock-lock remains intact, and cannot be opened by the burglars or the holder of the combination. On the other hand, when the clock-lock releases its bolt in the morning, the combination-lock still remains locked, and burglars cannot make an entrance to the safe. Such results cannot be accomplished by a clock-lock alone, because when it releases its bolt the safe is absolutely unlocked; nor by two or more combination-locks together, because the holders of the combination may be taken to be taken to the bank and forced to open the lock. Neither can tampering with the combinationlock affect the clock-lock. "The time-lock serves as a safeguard by night, in connection with the combination-lock, for holding the bolt-work in a locked condition; but when the time-lock releases the bolt-work at the appointed hour, the boltwork will remain locked, and the safe or vault-door closed, until the combination-lock is unlocked by the holder of the combination on which said lock is set, when the bolt-work can be retracted and the door opened, thus leaving the time-lock free from performing any locking action, which leaves the combination-lock free for use during the day for locking or unlocking the safe or vault-door- an important desideratum present in my invention. 66 If the time-lock present on the safe or vault-door is set for holding the bolt-work from the time the bank closes in the afternoon to release the bolt-work at a certain hour the next morning, it will admirably and with certainty perform its office, leaving the combination-lock to be opened before the bolt-work can be retracted; and should the officer of the bank holding the combination be seized during the night, carried to the bank, and forced to open the combi 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.

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.

"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.
