TO ALL WHOM IT MAY CONCERN:

Be it known that I, HEZEKIAH II. BRYANT, of the city of Boston, county ot' Suilolk, State of Massachusetts, have invented an Improvement in the Construction of Safes; and I do hereby declare the following to be ar full and correct description of' the same, reference being had to the accompanying drawings and the letters ot` reference marked thereon, making part ot' this specification. In said drawings- Figure l is a vertical view of a section of a'safe constructed as herein proposed.

The letters a thereon represents the first or outer case; cl the inner. case, enclosing a space between said cases. The letters c represents the vessels for holding water or other liquid; the letters I1 represents a. space or steam-chamber between the vessels c and the case a; the letters E represents the fixed tube, and letters f the flexible tube and float attached, both of said tubes showing a different mode for conducting the steam or vapor generated in the vessels c into the steam-chamber b, whence it escapes through the vent shown in the case a by the letter S. The letters L represents'the water or feed pipes for supply'mg the liquid to the vessels c; the letters Q shows the flanges or guards holding the liquid vessels in their intended position,

Figure 2 represents the door of the structure.

The letters g thereon the liquid vessel attached; that of E the steam-escape pipe; t the water-supply pipe.

In Letters Patent of the United States, recently granted to Ine, I have described and shown a method of rendering safes and 'other similar structures tireproof. My present invention is based essentiallyr upon that method, its object being to remove certa-in objections in the plan of construction of the safes described in said Letters Patent, 2'. e., to lessen the cost and labor. of making the same, and admit of ready access to the watervessels or chambers enclosed within the walls of the structure.

My invention consists of forming the several walls of a safe with the two cases a and d, made of the required dimensions or form. The case designated by a forms the rst or outer walls of the safe; that marked d forms the inner walls of the same, enclosing live sides of the space required for the vault or deposit place in the structure. These two cases also enclose a space between them suitablevto hold one or more liquid or water-vessels, for the purpose of generating steam or vapor, which it is known will prevent the struct-ure from 'being heated to a degree that would seriously injure it'or its contents. Upon one side of the liquid vessels, designated by the letter e, I place a flange or guard such as will keep them removed from the case a, so as to form a space shown by the letter Z1, for the circulation of any steam or vapor escaping from the liquid orwater-vessels, said steam or vapor escaping thence through the vent in the case a, `shown by the letter S. Each of the flexible tubes is provided with a float, as shown by the let-terf, and each of the liquid or walter-vessels is provided with such a tube, for the purpose of conducting 'the steam and vapor from said vessels into the space b, whence it escapes as before shown. It will be understood that the float attached to the free end of the tubefserves to carry the same to the surface ofthe water, regardless ofthe position in which the vessel is placed. Instead of using this flexible tube, one of a fixed nature, as shown bythe letters E, may be substituted. Such a tube would lead from the common centre ofthe water or liquid-vessel into the steam space I); and it will be readily seen that the vessels provided with suoli a tube, soadjusted, would remain about half full of the contained liquid, whatever position they were placed iu. The operation of each of these tubes isshown in the accompanying drawings. In constructing the outer case a one of its sides is made to attach to the others by rivets or otherwise. Any number of said sides may be se constructed, but I prefer to limit the number to one, locating the same opposite from that in which the door of the structure is placed.

My object in making one of the sides in a manner that renders its detachmentfrom the others inexpensive und practicable wit-hout serious injury to it or to the other parts of' the structure, (further than the loss of the rivets and the cost of removing the same,) is that of providing a means for the removal of the water or liquid vessels et any time when repairs might become necessary to the same. It being my object to build a structure that time alone will destroy, it is an object of much importance to have its several parts so constructed that they can be easily and inexpensively repaired, hence the provision for the removal of the water-vessels, as they would decay sooner than any other part of the structure. Each of the'water or liquid-vesselsis provided with a. pipe, shown by the letters L, leading from the exterior surface of thc case a into said vessel, for the purpose of supplying them with the liquid that they are intended to contain. The door of the structure is provided with one or more water-vessels, shown by the letter g, and witha Water-supply pipe, shown. by letter k, and a steam-escape pipe, shown by letter E.

Having fully described my invention, I wish it clearly understood that/I do not conne myself to the exact mode of construction herein set forth7 for the details ofthe same may be more or'less varied, while the essential features of it are retained.

I claim, and desire tot secure by Letters Patent-- 1. The combination, with the inner and outer Walls or cases of a. safe or other structure of asimilar nature7 of Water or liquid vessels or tanks, located between the said Walls or cases, under an arrangement substantially as herein described. I

2. .The combination with the cases a and d of the removable water or liquid-tanks er vessels and llanges er supports by which the same are held in position in the space intervening between seid eases, as and for the purposes described.

3. In a safe or other similar structure :is herein specified, I claim the construction and arrangement of one or more sides of the enter well or case, so that the saine may be readily removed without injury to the said structure, as and for the purposes shown and set forth.

The above specilication of my said invention signed and witnessed at Boston, this twenty-fifth (25th) day of June, A. D. eighteen hundred and sixty-seven (1867.)

H. II. BRYANT.
