position and mode of operation of the parts, and simplify my mechanical organization, as will fully appear by comparison. "What I claim as my invention is —

"1. The combination of independent multiple bolt-work with the time mechanism and locking or dogging mechanism of a time-lock, automatically both dogging and releasing the bolt-work at predetermined times, substantially as described.

"2. The combination, in a time-lock, of a continuously revolving adjustable device for determining the time of operation of the unlocking mechanism, a pivoted arm or lever actuated by said device, and a dog or obstruction movable directly by said pivotal arm at regularly-recurring periods, to permit the retraction of the bolt-work, substantially as described.

"3. In a time-lock, the combination of time mechanism, a revolving dial actuated thereby, a dog and suitable connecting mechanism, whereby the continuous revolution of the dial causes the dog to move into the locked and unlocked positions alternately, substantially as described.

“4. In a time-lock, the combination of a continuously-rotating dial and mechanism which causes the lock to lock and unlock automatically, substantially as described.

"5. In a time-lock, a continuously-rotating dial provided with an adjustable device for automatically determining the time of locking, substantially as described.

"6. In a time-lock, the combination, substantially as above set forth, of the time-movements and an adjustable device for automatically determining the time of locking.

"7. In a time-lock, the combination, substantially as above set forth, of the time-movements and two adjustable devices, one for determining the time of locking, and the other of unlocking.

"8. In a time-lock, the combination with the time mechanism and the locking or dogging mechanism, of an adjustable device which, through the continuous operation of the time mechanism, will periodically, or at required times, cause the lock to remain locked during a greater period than twentyfour hours, substantially as described.

"9. In a continuously-running automatic time-lock, the

combination, with the time mechanism and the locking or dogging mechanism, of an independent device adapted to be set to prevent, at any desired time, the unlocking of the lock for a greater period than twenty-four hours, substantially as described.

"10. The combination, substantially as above set forth, of the adjustable mechanism for continuously locking and unlocking daily the time-movements, and a device for preventing unlocking during a greater period than twenty-four hours.

"11. In a time-lock provided with two independent timemovements and an interlocking device common to both, the combination, with each of said movements, of a ratchet and pawl interposed between the last or driving arbor of each movement and the said common unlocking device, whereby the said device may be driven by either or both of the movements, and the stoppage of one movement will not necessarily cause the stoppage of the other, substantially as described.

"12. The combination, with the time-movements, of the wheels H and I, the ratchets K L, and the common wheel M, arranged substantially as described, for the purpose set forth.

"13. In combination with the dial, the seventh-day camwheel A, adjustable, as described, to prevent the falling of the bent lever R and dog V, either periodically or at required times, as described.

"14. The combination, in a time-lock, of time mechanism, a revolving graduated dial actuated thereby, a bent lever oscillated by the revolution of the dial on an immovable pivot, and a dog or obstruction, also oscillated on an immovable pivot, the lever and dog being so arranged that when one arm of the lever is pushed aside at a predetermined time by the revolution of the dial, the other arm withdraws its support from under and permits the dog to turn by gravity, thereby leaving a free space for the retraction of the bolt-work, substantially as described.

"15. The combination of multiple sliding bolt-work, a dog or obstruction oscillated on an immovable pivot, and tending, by gravity, to turn so as not to dog the bolt-work, a bent lever, oscillated also on an immovable pivot, for holding the
