Beit known that I, GEORGE H. IRELAND,

. of Somerville, county of Middlesex and State of Massachusetts, have invented certain new 1` and useful Improvementsin `the Construction u of Safes, Vaults, 8vo.; andthat the'following isa .full andxexact description `of the same, referencebeing had to the accompanyingdrawlng. .i

The object of the present invention is to provide a vault or safe vforthe ,reception of articles of value, &c wherein they will besecure 1 from thieves and re,.and from the action of f moisture, frost, or other atmospheric elements.

The invention "consists, first, of a vault or chamber constructed of stone or brick masonry, with the layers tied together by metallic straps, in combination with a metallic frame,

` -in which the door `of the vault is to besecured andlocked in any proper mode. This frame is arranged upon the interior of the vault,

" r against the walls thereof, `with which, as they are built, thesaid frame is constructed to vinterlock, becoming as it were a part and parce1 thereof. Second, `in combination with the above, the openin g into the vault is extended beyond the outside of the` said door thereto,

. and at such .extension adapted for another i door, which yin its construction, as also in the construction ,of the opening, is such as to rel sist the actionof fire and prevent the conduc= R1 Qtion of heat to the said inner door, between `which and the said outer chamber orspace.

door is left anair- In the accompanying drawingmy improvements inthe construction of vaults, Safes, Sac.,

Figure `1 being a central vertical section through avault constructed according thereto,

, i and with the entrance to the vault arranged in Y .i U l the top and ush or nearly so with the surrounding licor. or surface; Fig. 2,a `plan'or top view .d of the vaultshown in Fig.' 1,but with the doors removed, and with one side in partial horizontal section for more perfectly illustrating the I Construction of inside metallic frame Fig. 3,

a plan view in detail, to be hereinafter referred A in the drawing, Figs. 1 and 2, represents avault or chamber surrounded and inclosed `in part `or parts, or in the whole.

`upon its sides B and bottom C by masonry,

metallic straps F, producingl walls of the greatest solidity and rigidity, and equal to resist the operations ofthe most forcible attempts by burg-lars to displace them, either l The upper side'G of the vault is open, and at such, in the present instance, entrance to the` vault is ef- A fected. b, a lining of hydraulic cement to in-4 side surface of walls to vault; H, a frame made of iron or other suitable metal. This frame, in thepresent instance, consists of a part, I, made of a shape corresponding to that of the vault. This part I of the frame H, in the construction of the vault-walls, is located at the vault-entrance, and it is suitably formed to `interlock with the masonry, as shown at J The frame H also consists of vertical rods or bars K, that are rigidly fastened to the part I, one rod at each corner of the vault. These y.

rods extend down against the vault-walls, and at their lower ends are formed `to interlock with the masonry in its construction, as shown at L. The part I to the frame H is open in its center, and around the Ysame is constructed with a square shoulder, forming a seatY for the cover or door A provided for the vault, .as shown at a, which is suitably formed with a square shoulder therefor.` The cover E is made of metal in any Suitable mode of construction for strength, and it is to be provided with any suitable arrangement of bolts for locking it on and to the metallic frame H I. The opening G to the vault is extended bbeyond the door,

and at such extension constructed to forma seat, M, for an additional and outside door, N,1eaving a chamber or space, z, between the two doors. The door N is constructed of a metallic frame, O, shown in Fi g. 3, braced and stiffened by straps, P, intersecting each other at'the center of the frame, within which frame hydraulic cement is molded into the proper shape to produce the complete cover, shown in Fig. 1. The seat M fo`r the door N is also constructed of hydraulic cement, which is extended beyond'to form a hydraulic-cement `exterior coating for the upper ends of the vault-walls. Q, a case or cabinet made of wood or other material, suitably prepared to resist moisture and heat. This cabinet has hooks R iixed in its upper end, by which it is suspended from staples S to the under side of inner door E.

In Fig. 4. a modification in the construction of the vault is shown. It consists in extending the masonry, together with the part I of frame H, over the top of the vault and in narrowing the entrance into the same, as shown, the same principles of construction, however, being involved as in the vault hereinbefore described and illustrated in Figs. 1 and 2 of the drawing.

From the above description of my invention it is obvious that, first, with a vault or safe constructed for entrance through its top it is rendered susceptible of being on all its other sides completely banked and surrounded by. earth, reducing the danger of injury to its contents by tire, thieves, 85o.; second, but comparatively very little iron is used in the construction of the vault or safe, while at the saine time great st-rength is secured; third, between the outside and inside of the vault there is no direct or continuous communication by iron or metal, it being broken, as is obvious from the description and drawing, thus reducing the power of conduction of heat to the interior of the vault.

The doors of the vault may be hinged or not, according as may be deemed preferable.

Having thus described my invention, what I claim, and desire to secure by Letters Patcnt is- 1. A vault, safe, or chamber constructed, as set forth, of masonry, in combination with a metallic frame arranged to interlock with the said masonry, substantially as and for the purpose described.

2. In combination with the above, the entrance to the vault, constructed, as described, together with a door arranged to t therein, of hydraulic cement, substantially as and for the purpose specited.

The above specilication of my improvements in the construction of safes, vaults, 81e., signed by me this 1st day of February, A. l). 1870.
