LOCKING MECHANISM FOR. SAFES OR VAULTS.

SPECIFICATION forming part of Letters Patent No. 779,145, dated January 3, 1905.

Application filed June 18,1904. Serial No. 213,159.

To all whom, it may concern:

Be it known that I, JAMES HENRY WIL- LTAMS, a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Looking Mechanism for Safes or Vaults; and I do hereby declare the following to be a full, clear, and exact'description of the invention, such as will enable others skilled I in the art to which it appertains to make and use the same.

My invention relates to an improvement in locking mechanism for safes or vaults, the object of the invention being to provide im- 5 proved locking mechanism particularly adapted for use on emergency doors of vaults,which is simple in construction and operation and strong and durable in use; and the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation of the inner face of the 5 door, showing the same closed and locked. Fig. 2 is a view in cross-section thereof, and Fig. 3 is an enlarged detail sectional view.

1 represents the safe or vault door, and 2 the vestibule to receive the same. The door 3 1 is made circular with stepped or irregular outline in cross-section to fit snugly the opening of corresponding shape, and the door and vestibule are provided at regular intervals with interlocking lugs 3 and recesses 4: to absolutely prevent rotation of the door, after it is closed. To the inner face of the door a ring or frame 5 is secured by bolts 6 and provided with an outwardly-projecting flange or lip 7 at its edge to overlap and firmly hold 4 the locking-ring 8 in position yet permit the latter to freely turn on the bolt frame or ring 5. The locking-ring 8 is provided at regular intervals with lugs 9, adapted when the door is closed to move through correspondinglyshaped recesses 10 in the vestibule, and when said ring is turned, as will be more fully hereinafter explained, to move the lugs 9 out of alinement with the recesses 10 they will be disposed wholly or partially behind lugs or solid portions 11 of the vestibule, and the door 5 will be securely locked. A portion of the inner edge of ring 8 is made with a series of notches forming a rack 12, with which a pinion 13, located in a recess in the bolt-frame, meshes, and said pinion 13 is secured upon a journal 14, which latter projects through the door and has any suitable hand h old secured on its outer end to permit the pinion 13 and ring 8 to be turned to lock or unlock the door, as the case may be.

To control the operation of the pinion 13 and consequent operation of the locking-ring, any approved mechanism may be employed. I show for the purpose a time-lock 15 and combination- locks 16 and 17 for controlling 5 the movement of a plate 18, on which a rackarm 19 is provided, meshing with one side of a segmental gear 20, which latter also meshes with pinion 13 and either turns therewith or locks it against turning. 7 O

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I would have it understood that I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what 30 I claim as new, and desire to secure by Letters Patent, is

1. The combination with a door, and a vestibule having a seriesof recesses therein, ofa

ring on the inner face of the door, lugs on the ring to aline with and be moved out of alinement with the recesses in the vestibule, said rotary ring having a series of teeth, a pinion mounted on the door and engaging the teethon the ring and means for turning said pinion.

3. The combination with a door, and a vestibule having a series of recesses, of a ring secured to the inner face of the door, a rotary ring provided with a rack and disposed around the first-mentioned ring, the latter having a flange or lip overlapping the rotary ring, lugs on said rotary ring adapted to'move through the recesses in the vestibule, a pinion mounted on the door and engaging the rack on the rotary ring, a journal projecting through the door and secured to the pinion, and locking mechanism controlling the operation of the pinion.

4:. The combination with a door and'a vestibule having a series of recesses therein, of a ring securely bolted to the inner face of the door and provided at its edge with a flange or lip, a rotary ring around the first-mentioned ring and overlapped by the flange or lip on the first-mentioned ring, said rotary ring provided with a rack, lugs around the rotary ring adapted to move through the recesses in the vestibule, a pinion mounted in the firstmentioned ring and engaging the rack on the rotary ring, a journal projecting through the door and secured to the pinion, a gear mounted on the door and engaging said pinion and mechanism on the door for locking said gear.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JAMES HENRY WILLIAMS.
