JOHN STEVENS, OF GALION, OHIO.

VAULT-DOOR LOCK.

To all whom it may concern:

Be it known that I, JOHN STnvnNs, a citizen of the United States, residlng at Galion, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Vault-Door Locks, of which the following is a specification.

My invention relates to looks for covers for vaults, safes, safety deposit boxes and the like and its object is to provide a cover that may be permanently locked to the casing of the vault or the like against removal from the exterior of the casing or one side thereof.

The invention relates in the details of construction and arrangements of the parts of the device described hereinafter and illustrated in the accompanying drawings.

Said drawings illustrate the preferred embodiment, and therein Figure 1, is a plan view; Fig. 2, is a horizontal sectional view through a vault or the like showing the same inverted and its cover in inverted plan; Fig. 3, is a cross section on line 33 of Fig. 2; Fig. 4, is a detall showing the head and wedge plate in unlocked position; Fig. 5, is a detail sectlon show ng the head and associated parts in position for turning or movement to locked position, and Fig. 6, is a detail section on the line 55 of Fig. 2.

Throughout the drawings like reference characters designate like or corresponding parts throughout the views thereof.

Referring specifically to the drawings, 1

is a casing or body of a'vault, receptacle or i the like shown as having its rim extending inwardly to provide a continuous angle flange 2 at its opening. The opening at the flange is spanned by a cover 3. A stem 4 is mounted for sliding movement transversely of the cover and for turning movement in openings in the cover and in a bolt shifting plate 5, the latter arranged lnteriorly of the vault structure. From the plate extend outwardly a suitable numberof properly shaped bolts 6, the same being p1votally mounted on the plate as by means of fastening bolts or members 7. Auxiliary bolts 8 may be bolted or otherwise pivoted as 9 to the bolt 6. Suitable guide devices 10 for the bolts 6 and 8 are preferably employed having suitable enlarged openings through which the bolts pass and sultably fastened as by bolts at 11-to the cover 3. On the plate 5 is formed an offset, substan- Specificati on of Letters Patent. Patent d D 29 1914 Application filed December 18, 1913. Serial N 0. 807,484.

tially U-shaped frame 12 having an open end providing a slot to receive a wedge plate and a head now to be described, at suitable times. A wedge plate 13, is employed, having a bifurcated or forked end providing a slot 14' adapted to receive the stem as seen in Fig. 2. This wedge is carried by a spring wire 13 secured to plate 5. The slidable stem 4 has fastened to its inner end a head 14, shown as square to correspond to the shape of the recess defined by frame 12. Frame 12 forms an abutment for the head 14 upon turning of the stem 4, and the stem 4 in one position forms an abutment for frame 12; thus insuring movement of both the frame and stem upon movement of the stem. A latch15 is employed to engage a notch 16 in the periphery of the plate 5 and is slidingly mounted in the brackets 17 and carried by a spring 18 fastened to the cover 3. For a purpose later to be explained the stem 4 may be provided with a slot or aperture 19, to removably receive a pin 20. Stem 4 has exterior of the casing an operating or tool engaging head 21. I

When the cover is fastened as seen in Fig. 2, the same rests upon the exterior of flange 2, and the bolts 6 and 8 engaged against the interior thereof, effecting the locking of the cover. When thus locked latch 15 engages in slot 16, and wedge 13 is in the recess of I the frame 12 and head 14 is so positioned, as seen inFig. 3, that turning thereof by the manipulation of a suitable tool at head 21, will turn the same beyond the frame and thus not disturb the locking relation of the parts. It will thus be seen that the cover cannot be removed from the exterior without destruction of the vault. The cover may thus serve eliiciently in connection with a vault employing a door or closure member operable for unlocking from the interior of the vault, and may also serve efficiently in connection with a vault used for temporary burial of money or valuables. The bolts 6 and 8 are slidingly mounted but before placing the cover onto the vault casing the stem through sliding movement is moved outwardly so that the head 14 will extend into the recess of frame 12 as seen in Fig. 5, in which position the parts may be fastened by means of the key or pin so extending through the slot 19. Accordingly when the stem is turned in the proper direction for retraction of the bolts they are moved to position permitting the placing of the cover 3 onto the casing. /Vhen thus placed latch 15 is out of engagement with the notch 16 and the wedge 13 bears against the frame 12 or head 14, the latter feature being shown in Fig. 4. After thus positioning the cover the stem is turned in the proper direction to slide or throw the bolt to the locking position shown in Fig. 2. vVhen this position is reached, latch 15 enters notch 16 and arrests movements of the parts, resisting normal turning movements imparted thereto. At this time the wedge 13 is opposite the slot of frame 12. Pin 20, if employed, is then removed and the stem 4 pressed inwardly whereupon the head M is moved out of the slot and the spring 13 moves the wedge 13 thereinto. Thus the stem is locked against further sliding and turning of the stem thereafter will result in turning of the same alone without disturbing the relation of the locked parts. If access is afterward had to the interior of the vault, the vault is broken for that purpose, but if the interior of the vault is accessible otherwise than throu 'h the opening at the cover, latch 15 and wedges 13 are moved from looking position and stem 4 is thereupon properly adjusted to retract the bolts so that the cover can be removed.

As merely the preferred embodiment has been illustrated and described it is to be understood that changes such as fall within the spirit and scope of the appended claims are reserved.

Having thus described my said invention what I claim as new and desire to secure by Letters Patent is:

1. In a device of the class described, a cover, a stem slidable in a plane substantially at right angles to the cover, a plate turnable at times with said stem, said stem cotiperating with said plate and cover, and means operable through movement of the plate to lock said stem against sliding movement, for the purpose specified.

2. In a device of the class described, a cover, a movable plate, a rotatable stem slidable transversely of said plate and cover and a wedge member operable through movement of the plate to lock said stem against sliding movement.

In a device of the class described, a cover, a plate provided with a slot, a stem slidable transversely of said cover and plate and having a head thereon engageable with said slot and a wedge associated with said parts to enter said slot and lock said stem against sliding movement.

4. In a device of the class described, a cover, a turnable plate, a stem slidable transversely of the cover and plate, means to arrest movement of said plate and maintain plate against movement, and means to lock said stem against sliding movement operating automatically upon the arrest of movement of the plate, for the purpose specified.

5. In a device of the class described, cover, a turnable plate, bolts carried by said plate, a rotatable stem slidable transversely of the cover and plate, a head on said stem, said plate provided with abutment means engageable by said head, and a wedge engageable intermediate said plate and head to lock said stem against sliding movement to engage said abutment means.

6. In a device of the class described, cover, a turnable plate, a rotatable stem slidable transversely of the cover and plate, an abutment member on said plate, an abutment member on said stem engageable with said abutment member of the plate, and means to fasten said stem in position preventing abutment of said abutment members with each other.

7. In a device of the class described, a cover, a turnable plate, a rotatable stem slidable transversely of the cover and plate, a latch for said plate, bolts, an abutment member on said plate, an abutment member on said stem engageable with the first mentioned abutment member, a wedge, a spring associated therewith, said wedge adapted to lock said stem to prevent abutting engagement of said abutment members with each other.

In testimony whereof I afliX my signature in presence of two witnesses.

JOHN STEVENS.
