SAFE.

SPECIFICATION forming part of Letters Patent No. 512,022, dated January 2, 1894.

Application filed March 6, 1893- To all whom it may concern.-

Be it known that I, EBENN. GOWER, J r., of Flowery Branch, in the county of Hall and State of Georgia, heWe invented a new'and Improved Burglar-Proof Safe, of which the following is a full, clear, and exact descrip tion.

The object of the invention is to provide a. new and improved burglar proof safe, which is simple and durable in construction, and formed without apertures in the outside part of the door, to prevent burglars from tamper- The invention consists of certain parts and details and combinations of the same, as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional plan view of the imtion of the same on the line 2-2 0f Fig. 1 Fig. 3 is a'transverse section of' the same on the line 33 of Fig. 1. Fig. 4: is a like view of part of the same in a diiferent position. Fig. 5 is an enlarged sectional plan view of part of" the bolt actuating mechanism; and Fig. 6 is a sectional side elevation of the combination lock arrangement for the cam.

The safe A is provided at its front end with the usual hinged door B on the inside of which is arranged the bolt mechanism 0 of any approved construction and adapted to engage with its several bolts corresponding recesses D in the walls of the safe A. One of the bolts 0 of the bolt mechanism 0 is adapted to be engaged by the wedge-shaped head E of a transversely-extending bar E mounted to slide in suitable bearings E on the inner face of one of the walls of the safe A. When the door B is closed and the several individual bolts of the bolt mechanism G are in alignment with the recesses D,and the bar E is pushed forward, then the head E presses on the said bolt 0 to actuate the bolt mechanism O to engage the individual bolts of the latter with the recesses D to lock the door B, in place.

In order to unlock the bolt mechanism, I provide a lever F pivoted to the inside of the Serial No. 464,712, (No model.)

door, see Figs. 1 and 5, and engaging with one end a recess 0 near the outer end of the bolt 0', the other end of the said lever being adapted to swing onto the inclined back E of the head E when the bolt 0 is actuated by the forward wedge-shaped end of the head E. Now, when the bar E is moved rearward, the lever F travels up the inclined back E so as to impart a swinging motion to the said lever, which, by its connection with the bolt 0' causes the latter to move outward, thus actuating the bolt mechanism so as to withdraw the individual bolts of the latter from the recesses D. The door B is then unlocked and can be opened in the usual manner.

Near the rear end of the bar E is pivoted a cam lever Ghaving a hook-shaped head G held byits own weight in peripheral contact with a cam I connected bya combination lock arrangementH of any approved construction, with the longitudinally-extending shaft J mounted to turn in suitable hearings in the side walls of the safe A, as plainly shown in Fig. '1. The cam I is provided with a shoulder 1 adapted to engage the head G so as to exert a pull on the latter to move the bar E rearward for the purpose of opening the door B, as above described. The shaftJ turns the cam I only when the said shaft is turned according to a predetermined combination, the combination lock arrangement I-I then turning the cam I in the direction of the arrow a to move the shoulder in contact with the head G and to exert a-pull thereon to move the bar E rearward for opening the door locking mechanism.

On the shaft alongside the cam I is secured a second cam K which presses against the rear end of the bar E so as to impart a forward sliding motion to the latter when the shaft J isturned. Thus, one cam serves to move the bar in one direction to actuate the bolt mechanism to lock the door, while the other cam serves to shift the bar backward to again actuate the bolt mechanism to unlock the door. When the cam K pushes the bar E forward to lock the door, the head G of the cam lever Grises out of the shoulder l in the cam I, the said head traveling up the periphcry of the cam; and when the cam K reaches its greatest distance horizontally and forwardly then the lower hook end G of the lever G moves into a V- shaped notch E formed on one of the bearings for the bar E as plainly shown in Fig. 3. The lever G is now locked in place, as the head G rests firmly on the cam I and the lower end G2 of the lever G is engaged with the notch in the fixed bearing. The bar E is thus held in a locked position by the locked lever G. If the lever G were not locked the bar E would slide back in case the safe were placed on its back, or subjected to jar, 850. One end of the shaft 'J extends into a compartment L arranged in one side of the safe A, and on this inner end of the shaft J is secured a bevel gear Wheel J in mesh with a bevel gear wheel N secured on a transversely-extending shaft N mounted to turn in suitable bearings arranged in the back and front wall of the separate compartment L. See Fig. 1. The front end of this shaft N extends to the front of the safe and is provided on this end with the usual dial 0. By turning the knob of the dial 0, the shaft N is rotated in one direction to cause a rotary motion of the shaft J byv the gear wheels N and J and when the knob O is turned in the opposite direction, a reverse movement is given to the shafts N and J. When the knob of the dial is turned to the proper predetermined combination, the cam K is turned as previously explained to first unlock lever G and then exert a pull thereon to draw bar E rearward. When the door has been swung shut, and the cam K has pushed the bar E forward and outward to actuate the lockingmechanism 0 to move the individual bolts of the latter, in engagement with the recesses D, then the lever F swings onto the back E of the head E, and only the return movement of the bar E causes the said lever F to swing to unlock the bolt mechanism 0. The door B can then be opened. It will be seen that by this construction, no apertures whatever are formed in the face of the door, so that burglars cannot get at the bolt mechanism on removing the usual combination lock arranged on the door, as is the casein ordinary safes. Tampering with thecombi'nation lock H is not possible as the'lock is inside of the safe and only the dial 0 is on the outside, and in case the latter is removed, it does not affect the combination lock H and bolt mechanism C, so that the safe cannot be opened. Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a safe provided at one end with a transverse partition extending from its front wall to its rear wall and forming a closed compartment, of a safe bolt work mounted on the door, a dial shaft extending through the front wall of the safe to the rear end of said closed compartment and bolt operating mechanism within the main compartment of the safe and connected with the rear end of the said dial shaft through the- 'rear end-of the said partition, substantially as set forth.

2. The combination with a safe having a separate and independent closed compartment to one side of its door opening and main compartment, of a bolt work on the safe door, a dial shaft extending through the front of the safe into said compartment, a counter shaft extending through the said partition and geared to the dial shaft, a combination mechanism on said counter shaft, and bolt operating mechanism to be actuated from the counter shaft upon properly actuating the said combination mechanism, substantially as set forth. A

- 3. The combination with a safehaving a separate and independent closed compartment to one side of its door opening and main compartment, of a bolt work on the door, a dial shaft extending through the front wall of the safe to the rear of said closed compartment and adaptedto actuate from its inner end the bolt work and an intervening combination look at the rear of the safe, substantially as set forth.
