LOCK FOR SAFETY-DEPOSIT VAULTS AND THE LIKE.

Application filed December 5. 1921. Serial No. 519,850.

T 0 aZZ whom it may concern:

Be it known that we, Pn'rnn M. W'non and EDGAR ANnnnsoN, citizens of the United States of America, residing at (irand Rapids and Manitowoc, in the counties of Kent and Manitowoc and States of Michigan and Wis consin, respectively, have invented certain new and useful Improvements in Locks for Safety-Deposit Vaults and the like; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a lock for safety deposit vault doors, primarily, though it is applicable to safes, or other allied structures as well. We have shown the invention used with doors of safety deposit vaults like that shown in United States Patent No. 1,387,818, issued August 16, 1921. wherein the lock on the rear side of the door is safeguarded against being driven from the door. The present invention safeguards the door from being opened forwardly in any manner as by engaging under the side edge thereof and prymg it open which can he done in some cases.

It is a primary object and purpose of the present invention to make a comparatively simple and economically constructed lock of this character by means of which the door is locked at both top and bottom simultaneously with the side locking thereof, the lockin bolts for such top and bottom locking belng located within the body of the door so that the same cannot be easily disconnected therefrom when the door is in locked position, in fact. the locking bolts will have to be broken off in order to get the door open. A further object of the invention is to make a structure of this character which is particularly easy to use with the construction of the patent above noted so that a full safeguard against any unauthorized entrance into a safety deposit vault equipped with the two inventions is made. Many other objects and purposes together with novel constructions for attaining the same will appear fully and in detail as understanding of the invention is had from the following description, taken in connectionwith the accom panying drawings, in which,

Figure 1 is a perspective view showing the invention in its application to doors of safety deposit vaults.

Fig. 2 is an enlarged vertical longitudinal section through a vault cell, showing the usual lock in side elevation and the auxiliary locking bolts and the means of operating the same in side elevation.

Fig. 3 is a horizontal section substantially on the plane of line 3-3, of Fig. 2, looking downwardly as indicated by the arrows.

Fig. 4 is an enlarged front elevation, with parts of the door and adacent portions of the walls of the vault cell broken away and in section to disclose interior construction, and

Fig. 5 is a transverse vertical section on the plane of line 55, of Fig. 2 looking forward as indicated by the arrows.

Like reference characters refer to like parts in the different figures of the draw ings.

The invention is shown in Fig. 1 in connection with a vault containing two cells, sufficient for the illustration of the invention, it being understood that the invention is applicable to the door of each cell in a safety deposit vault, irrespective of the number of cells used. It is also applicable to doors used in many other places. as in safes or the like structures. The vault has a top 1, a bottom 2, back 3 and sides a a partition 4* paralleling the sides 4 and dividing the vault into two cells, the front sides of which are open, being adapted to be closed by doors 5 mounted for swinging adjacent one vertical edge in the usual manner. At the front of each cell, a portion of the under side 1, and of the upper side of the bottom 2 is cut away, forming the shoulders 6 and 7, respectively, as shown. A lock casing 8 inside of which the lock mechanism is placed is located against the back of each door 5, a back plate 9 of sheet metal closing the hack of the casing 8 and attached by means of screws 10 which, passing into the door, serve to securely attach the lock casing to the door at the same time the plate is secured to the lock casing. A vertical bar 11 is permanently secured to the plate 9. by electric spot welding or otherwise, and when the door is in closed position, the ends of the bar come directly in front of shoulders 6 and 7, thereby making it practically impossible to drive the tionary lock casing 8 lock from the door by stripping the threads from screws 10, as is now done in instances of robbery of safety deposit vaults.

The construction so far described is substantially the same as that disclosed in the patent above mentioned. A proper' safcguard is made against driving), the lock to the rear from the door but not against pryin; the door open by insertion of a pry between the free vertical edge of the door and the adjacent side of the vault. )ur invention is chiefly concerned therewith.

The laterally movable locking bolt 12 of the lock mechanism within the lock casing is adapted to enter a slot 13 cut to receive its outer end in the side of the side 4 of the vault. The bolt 12 has a slot 14 cut in one side, receiving a pin 15 on a disk 16 secured at the inner end of or formed integral with a key receiving barrel or tumbler 17 rotatably mounted and extending through the door to the front side thereof. The barrel 17 is limited in rotative movement by a pin 18 fixed with respect to the relatively staand received in an arcuate recess cut in a side of the disk 16 as shown in Fig. 5.

An arm 19 secured at the inner end of a second key receiving barrel 20, also rotatably mounted and extending through the door to the front side thereof is adapted in one position to come against the inner end of the locking bolt 12 and prevent inward more ment thereof until moved out of the way, this being done by the insertion of a master key into barrel 20, such key being in the possession of the vault attendent. This construction of lock, while practical and operative is not in itself new, nor is it.the only type of lock of this character with which our invention can be used.

On one of the barrels. preferably the one indicated at 17 and which is operated by the key in possession of the possessor of the vault cell, a gear 21 is cut, the same being received in a recess 22 therefor cut in the rear side of the door 5. Two cylindrical vertical openings and 24 are bored in the door, the first extending upwardly from the lower edge of the door and the second downwardly from the upper edge of the door, both the recess 22- but at opposite intersecting sides thereof. Additional locking bolts 25 and 26 are slidably received in the openings 23 and 24, having racks 27 and 28 cut on their inner sides at their inner ends to mesh with the teeth of the gear 21. It is obvious that on rotative movement imparted to the barrel 17. the . bolts 25 and 26 are simultaneously and equally moved but in opposite directions. Openings 29 and 30 to receive the outer ends of bolts 25 and 26 are made in the upper side of the bottom 2 and in the under side of the top 1,,as shown in 4, being located to freely receive said ends when the same are projected outwardly with the turning of the barrel 17 tomovc the first locking bolt 12 outwardly to enter the groove or slot 13.

The door of the vault cell thus equipped is insured against opening by outward prying, being locked not only at its side edge but at its upper and lower edges. ll 'hile prying outward on the door may strip the threads from screws and let access to the cell he gained if only the one bolt 12 is in service. with the bolts 25 and 26 projected outwardly and in openings or recesses 29 and 30, to open the door, such bolts must be broken off, an almost impossible proceeding. ln fact, for all practical purposes it cannot be done. The door is positively and absolutely held and the only way to gain access to the vault cell is by use of the proper keys in the barrels 17 and 20.

The construction described is practical. durable and eflicient in every particular. While it has been shown in connection with a two-key lock, it is evident that so far as the operation of the three locking bolts are concerned, the barrel may be very well eliminated. Furthermore it is obvious that either or both barrels 17 and 20 may be equipped with the operating gear for the operation of the two bolts and 2G, and such bolts associated with the gears, a double set of bolts 25 and 26 being used if desired. Many other variations in constructural detail from the specific disclosure made may be resorted to without de 'iarting from the invention which is deiined in the appended claims, the invention comprehending all forms of structure that come within the sco we of such claims.
