Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed July 17', 1917.. Serial No. 131,038.

To all whom it may concern Be it known that I, HARRY W. HELLER, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have made certain new and useful Improvements in Burglar-Proof Sales or Vaults, of which the following is a specification.

My invention relates to improvements in burglar proof safes or vaults and consists in the combinations, constructions and arrangements hereinafter described and claimed.

The present invention is a division in part of a prior application Serial No. 51997 filed tdeptember 22, 1915. In said prior application means was disclosed for locking the doors of the safe or vault and the present invention is an improvement in the specific form of locking means as well as in the provision of auxiliary dead locking means which are controlled by combination locks.

An object of my invention is to provide means which is dependent upon a time lock and an automatic device for dead locking the means which prevents the opening oi the doors of the safe or vault.

it further object of my invention is to provide an auxiliary means for dead locking the door retaining means when the time lock and automatic device are in position to permit the release of the door retaining means. A. further object of my invention is to provide a novel means for operating certain counter-weight door retaining means Other objects and advantages will appear in the following specification and the novel teatures of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application in which- Figure l is a. horizontal section through the device.

Fig. 2 is a horizontal section on the line 2-2 of Fig. 5.

Fig. 3 is a vertical section on the line 3-3 of Fig. 1.

Fig. t is a vertical section on the line H of Fig. 2.

Fig. 5 is a section on the line 5-5 of Fig. 2.

Fig. 6 is a perspective view of the counterweights.

Fig 7 is a perspective view of the time lock and automatic device and the look ing means connected therewith.

Fig. 8 is a face view of the safe or vault.

Fig. 9 is a rear view of the combination locks and V Fig. 10 is a section on the line 10-1O of Fig. 9.

Referring now particularly to Fig. 1, I have shown therein a casing 1, which may be made of steel or any suitable material and which has at the rear thereof a hinged grating or door 2. At 8 I have shown brackets carried by the casing. Those brackets form journals for the hinges of the doors 5. The latter are stepped at their edges as shown at 5 to engage recesses 6 in the walls of the casing or jambs when the doors are in their closed position. These doors swing inwardly in the interior oi. the casing 1 as shown. The means for operating the doors are alike for each door and a description of one will sutlice for both. It will be noted, that on the exterior of the casing are hand wheels 7. Each hand wheel has a shaft 8 which is provided with a bevel gear 9 arranged to engage a gear 10 on a stub shaft 11. The gear 10 engages in turn a gear 12 which meshes with a bevel gear 13 on a shaft let. This shalt 14- has a gear 15 mesh ing with a gear 16 on a shaft 17. It will be obvious that when the hand wheel 7 is turned the shat't 17 will also be turned. On the shaft 17 is a pinion 18 which is arranged to engage a rack 19 which is secured to movable counter-weights 20 and 21 in the manner hereinafter described, the arrangement being such that when the hand wheel 7 is turned the pinion 18 will also be turned and the door 5 will be closed or opened by the movement of the pinion along the rack 19 depending upon which way the wheel is turned. This feature was set forth in my prior patent application aforesaid Referring now to Fig. 6, I have shown therein an upper member 20 already mentioned, and a lower member 21. Secured to the upper member 20 are side members 20 and 20". while secured to the lower member 21 are side members 21 and 21 respectively. The members 20 and 21 together with side members 20 and 20 form counterbalanceweights. The side members are provided with guides 20* and E21 respectively for guidingthe two sets of weights in their movements. In Fig. 3, I have shown the means by which these weights may be moved. This comprises a hand wheel 23 which is disposed on a shaft 24.- bearing a a slidable locking bar ea a guide for the counter-balance parts when" they go up or down.

The lower member 21 has a pair of slots 21 which are arranged to receive the lugs 30' of a slidable locking bar 30 which is dis posed beneath the member 21 a. shown in Fig. 5. The sli'dable locking bar 30 is for the purpose of dead locking the members and 21 which in turn serve to retain the doors 5 in their locked position as will be eX- plained later. The locking bar is controlled by means oi a time lock and automatic device. The time lock and automatic device are of any suitable type. In Fig. 7, I have shown the time loclr at 31 and the automatic device at 32. The trigger 31 of the automatic device is arranged to be engaged by a bell crank lever 33 which is pivotally mounted at, 3%, and which is connected with a link 35. A stop 36 limits the movement of the bell crank lever. The link 35 extends downwardly through a guide 36 see F i 7 and terminates immediately above an arm 38 carried by the lower, counter-balanced member .21. The automatic device controls a lever 39 which is pivoted at 40, and whose lower end engages a lever 4-1 pivoted at 42 and connected at 43 with one end of the slidable loclringbar 30.

' a similarly inwardly movable member L5 these being common in locks of this type. These two movable members and 45* are connected by means of a link 46 which is slotted at T7 to receive a pin l8 carried by Th latter resigned to extend underneath the upper side member 20 of tie counter-balance weights so as to prevent the movement of the countor-balance weights together until such time as the bar i9 is withdrawn. As will be seen from Fig. 10, this bar 49 isheld by plates 50 on each side thereof.

From the foregoing description of the various parts of the device, the operation thereof maybe readily understood.

Fig. 1 shows the doors in their open position in which they .are swung inside of the casing Prior to the closingof the doors a foot bridge consisting of three hinged sections 51, 52 and see 3, may be folded,

essee? the section 51 upon the section 52 and the two latter being swung back and resting against the grating or door 2 as disclosed in my prior patent aforesaid. The . members 20 and 21 are in the position shown. in Fig. 3, that is to say, out of the way oi the doors. The time lock and automatic" device are wound and the wheels 7 are manipulated to close the doors in the manner described. The wheel 23 may now be operated so; as to bring the members 20 and 21 in position behind the doors, these positions being shown in dotted linesin Fig. 3,so as to prevent the opening of the doors. The forward move ment of the counter-weight 21 causes the arm 38 to engage the rod 35 thus swinging the bell crank lever'against the trigger 31 and tripping the automatic device which thrusts the slidable locking member 30 into its locking position, that is to say, out of registration with the openings 21 thus dead locking the counter-weights and preventing the opening of the safe or vault until such time as the time lock 31 oil the automatic device which will shift the slidable locking member 30 into the, position shown in Fig. 5, thereby permitting the unlocking oi the vault or safe.

At times it may be desirable to close and lock the vault for a few minutes or for few hours during the day, without setting the time lock and automatic device, and this may be done by means of thecombination locks, for when these are set the slidable bar 49 is brought beneath the member 20 thus dead locking the counter-weights which retain the doors in their closed position until such time as the locks are manipulated to withdraw the slide 49 as already explained.

It will be noted, that the time lock and automatic device are located within the vault. The drilling of the outer casing of the vault is ineiiective as tar as opening the vault is concerned, because of the fact that these devices are not in a position to be tarnpered with even should the burglars manage to drill through the outer casing.
