BANK-VAU LT.

SPECIFICATION forming part of Letters Patent No. 428,241, dated May 20, 1890.

Application filed July 16, 1889. Serial No. 317,735. (No model.)

To all whom it mag concern: T

Be it known that I,CHARLES O. YALE, of the city, county, and State of New York, have invented certain new and useful Improvements in Burglar-Proof Bank-Vaults, whereof the following is a specification, reference being had to the annexed drawings, in which Figure 1 represents the vault as seen from the front, showing a part of the surface broken away and exhibiting the construction of the walls. Fig. 2 is a horizontal transverse section showing a part of the floor-plates broken away, exposing the metallic floor.

My invention relates to bank-vaults inclosed by metallic walls, floor, and roof of interlocking railroad-rails, outside of which on all sides is the masonry surrounding the whole.

The improvement embodies a new system of constructing the metallic walls, whereby the railroad-rails are protected, the power of resistance is increased, and the cost is reduced.

In constructing the Vault according to my improvements a foundation A is prepared, as usual, and on this is laid thick drill-proof plates B of steel, or steel and iron welded, covering the foundation completely. These plates are bent at the corners and carried up vertically, as C. The wall D of railroad-rails, the construction of which is well understood, is laid upon and against these plates with the base of the rails outward, and the plates are secured to the rails as they are laid in place to form the walls, floor, and roof. -On the inside face of the rails other plates E are applied, covering the floor F of railroad-rails, the wall D, and the ceiling, and secured to the rails, as in the case of the outer plates I C. The metallic Wall is thus composed of the railroad-rails laid up within an inner and an outer sheathing of steel, covering and protecting the entire structure within and without. This construction of metallic Wall is less expensive than that wherein the railroad-rails are sustained by angle-iron applied at the corners and a lining of two or more thicknesses then applied to the inside. A single thickness of drill-proofplate outside the wall, with the same inside, is superior to a number of thicknesses applied to the inside only. At the same time the angle-form sustaining-irons for the corners are superseded, thus reducing the aggregate cost,while in creasing the security. The usual mason-work G, of brick or stone and cement, is built around the metallic wall aforesaid. In practice I cause a number of steel bars H to be embedded in the wall to increase the difficulty of gaining an entrance through it, and care is taken to lay the inner course of these bars directly against the outer steel sheathing of the wall D, whereby additional protection is given to such plates by increasing the difficulty of removing them, in case the effort to penetrate the vault should reach so far.

I claim as my invention- 1. In a bank-vault, the combination, with a wall built from railroad-rails, of an out-side shell and an inside lining of steel plates for holding the rails in position and protecting the surface thereof.

2. In a bank-vault, the combination, with 'a the outer sheathing of steel plates, as set forth.

In testimony whereof I have hereunto set my hand this 29th day of June, 1889.
