WILLIAM J. BARNES, OF PITTSBURG, PENNSYLVANIA.

SAFE.

SPECIFICATION forming part of Letters Patent N o. 651,288, dated J' une 5, 1900.

Application tiled August 16, 1899. Serial No. 727.429. (No model.)

To all whom, t may concern,.-

Be it known that I, WILLIAM J. BARNES, acitizen of the United States of America, residing at No. 308 Oakland avenue, Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented cert-ain new and useful Improvements in Safes; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, which form a part of this specification.

My invention relates to certain new and useful improvements in safe-doors; and it consists in certain details of construction and combination of parts, as will be fully described hereinafter.

My aim is to produce a safe fitted with my improved screw-door and any approved timelock for use of bankers, brokers, and business men who are accustomed to open their safes in the morning and keep them open until businesscloses. This safe especially appeals to such business men on account of the despatch with which it can be closed and locked. A quarter-revolution of the handles suflioes to screw the door home, and the timelock immediatelylocks the safe and keeps it locked until thetime set for opening. Thus in case of attempted robbery a quick man can lock the safe in a flash and would-be robbers are completely foiled, and this door litted to a burglar-proof safe becomes impregnable.

To enable those skilled in the arts to construct and apply my improved door, I will proceed to describe it, reference being had to the drawings accompanying and forming a part of this specification, in which- Figure lis a front elevation of a safe, showi ng my improved screw-door in place thereon. Fig. 2 is a similar view showing safe-doors thrown open. Fig. 3 is a side elevation of the safe-door complete. Fig. 4 is a rear elevation of the safe-door.

In describing my invention in det-ail, similar figures of reference indicating similar parts throughout each and every view, 1 indicates the outer plate of the door, 2 the inner plate, and 3 the circular door proper, bearing the segmental threads 12, of which six are shown, and constructed of such shape that a quarter-revolution of the handles 8, operating shaft, will securely close the door. This door 3, which is formed integral with the plate 2, is mounted on a 'shaft 4, which pierces the outer plate 1 and is completed with a hand-wheel 7, supplied with handles 8, and a collar 5, provided with arms 6, is formed integral with the shaft and provided with pins 9, formed with circular heads 10, the pins running in grooves 9' when the door revolves and strengtheningl the same. The door is pivotally mounted at 14 on carrier 15 by means of plate 11 and pin entering hollow cylinder 14, and said carrier 15 -is mounted on safe by means of hinges 1G, and the door is secured by time-lock 13.

The operation of the door is very simple. The door -is pushed against the opening and the segmental threads 12 enter openings of threads 17, formed in safe,and a quarter-revolution on the hand-wheel 7 screws them home, the said movement of the hand-wheel 7 operating mechanism within the lock to lock the door until the time set for time-lock to open.

Changes in the details of construction do not alter the general spirit of my invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is as follows:

l. In a safe-door of the class described the combination of a circular door bearing segmental threads, the threads designed to engage similar threads formed in the safe, and pivotally mounted` by means of a shaft on a face-plate, the said shaft having arms bearing pins designed to move in grooves formed in said face-plate and said shaft being provided With hand wheel and grips, designed to revolve the door, the said face-plate being pivotally mounted on a carrier, which in turn is pivotally mounted on the safe, substantially as shown and described.

2. In a safe-door of the class described, the

combination of a circular door bearing Segmental threads, designed to engage similar threads formed in the safe, and pivotally mounted, by means of a shaft, on a face-plate, the said shaft having arms, bearing pins, designed to move in grooves formed in said face- ICG plate, and provided with a hand wheel and fixed mysignature in the presence of tivo subgrip,thesaid fece-plate beingpivotally mouutscribing Witnesses. d ed on a carrier, which is in turn pivotally mounted on the safe, and the door provided VILLIAM 'T' BARNES with a time-lock of approved design, substmi- Vitn esses: taliy as shown and described.

In testimony whereof I have hereunto af H. E. BECKER.
