' Specification of Letters Patent.

Patented July 29, 1919.

Application filed February 21, 1918. Serial No. 218,536.

To all whom it may concern:

Be it known that I, ARNOLD HINKENs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Bank-Vaults, of which the following is a specification.

This invention relates to bank vault structures, and its object is to provide a wall construction by which the vault is rendered completely burglar-proof, and more particularly immune to being cut or pierced by the flame of an oxy-acetylene or other torch emitting a flame of intensely high temperature.

The object stated is attained by means of a novel combination and arrangement of reinforcing elements embedded in a concrete wall as will be described in detail hereinafter, and in order that the invention may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing,

Figure 1 is a plan view of a fragment of the wall, and

Fig. 2 is an elevation of the. reinforcement and armor.

Referring to the drawing 5 denotes the monolithic concrete wall of a vault or similar burglar and fire-proof inclosure of a bank or other institution. The drawing shows only a fragment of two adjacent walls as this suflices for an understanding of the invention, it being understood that the structure of all the walls is the same. The wall has a metal reinforcement composed of longitudinal rods 6 embedded therein adjacent tg its faces, and vertically embedded rods 7. The wall is further reinforced by horizontally extending transverse rods 8.

In the wall 5 are also embedded semisteel plates 9 located midway between the opposite faces of the wall and arranged in horizontal courses, with the plates of one course breaking joint with the plates of the adjacent courses. The wall is therefore formed with a solid internal metal armor throughout its entire area. The ends of the plates interlock, they being formed with hooks 10 for this purpose. All the plates are cast with square holes 11 through which the transverse reinforcing rods 8 pass.

The plates 9 are also reinforced by vertical rods 12 cast therein near their ends, the plates being here thickened, as shown at 13. The purpose of the rods is to reinforce the plates sufficiently to successfully withstand warping from the blows of a sledge hammer or other heavy impacting appliance.

By embedding the plates 9 in the concrete wall 5, the wall is rendered completely burglar-proof. It will be practically impossible to cut the plates with an oxy-acetylene torch or similar apparatus, even if one side were exposed by removal of a portion of the concrete, as the opposite side would still be covered and would therefore not allow the molten metal to fall through. The plates can also not be broken with a sledge hammer in View of the reinforcement 12. If the wall should be cut into on one side, the reinforcements 6 and 7 on the other side will stop the plates from being driven through the other side. It will be noted that the holes in the plates through which the rods 8 pass are larger than the latter, so that the concrete material fills the space in said holes around the rods, whereby the plaltles are further securely anchored in the wa On the faces of the plates 9 are anchoring lugs 13 which are embedded in the concrete and act as a lock to strengthen the hold of the latter on the plates.

I claim:

A bank vault having a reinforced concrete wall, and metal plates embedded therein and arranged to form a solid internal burglar-proof armor extending throughout the entire area thereof, said plates having interlocking ends, and being arranged in horizontal courses, with the plates of one course breaking joint with the plates of adjoining courses.

In testimony whereof I afiix my signature.

ARNOLD HINKENS.
