IMPROVEMENT yin LIQUID-SAFE.

'Y iige tlgemlt meint it it these Entert @that mit mating auf tf tige same.

TO ALL WHOM IT MAY CON CERN:

Be it known that I, GARRET D. ANDERSON, of Montrose, in the county of Westchester, and State of New York, have invented a new and improved Oil and Liquid-Safe;and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexeddrawing, which forms part ot' this specification. v i My invention consists in the construction of a metallic tank, for containing oil or other inammable liquid, with a bottom so formed that `the same shall `incline from two sides to a central point, where a depression or' groove is' formed, which increases lin depth to the point where the faucet enters the same, whereby I am enabled to construct the tank with fewer-seams than` has hitherto been done, and at the same time provide a tank from which all the oil or other liquid it contains can be drawn ed', and Without liability of thesedimentcollecting at any point, to impede the perfect flow of the liquid from the safe.

It also consistsin'the combination, with a tank so formed, of an enclosing case of wood, metal, or other suitable material. v n Y,

It further consists in the combination,with such tank and its enclosing case, (whether the latter be Aof wood or.other materiah) of a lining nr filling of fire-proof material, so that if the outer case be made of wood, and the-same burn up, the tank will still be protected, and so that if the outer case be made of metal, the heatw'ill be prevented reaching the inner case, to fire the oil or other'inilammable liquid contained therein.

In the accompanying drawing- I Figure 1 represents a vertical central section through the safe, taken ou the plane of the line x iig. 2, and

Figure 2 is a diminished view'of the bottom ofthe same, introduced more especially to show the formation of the groove for draining the tank. A designates :an-.enclosing case or box, of any suitable form, and of any suitable material. In the present instance, it is shown as being constructed of wood, and of rectangular form. This box is provided with an opening at its top, andalid erdoor, a, to close said opening.

B is a metallic tank, enclosed in the ease A, and it is also provided with an opening at its top corresponding with the opening` in the case A; and b is a necksecured to said tank around the opening, which neck passes up through the case A, and is provided with a metallic lid or cover, c, fitted inside the lid or cover a.

lThe manner in which thistank is constructed constitutes one part of my invention. One principal object has been to construct the tank with asl few seams as possible, not only to save in expense, but to prevent leakage, which is always a contingency occurring at tlie'seams of a-liquidtvessel. I have shown the body of the tank as containingbut two seams all round, which occur where the sides of the tank are secured to the part shown by the blue line in fig. 1. To explain: a strip of sheetV metal, of the width it is desired .to have the tank, is taken, and one end placed so that its edgejwill'forrn one side of the mouth of the tank. It is then bent as shownath j 7c l, and, by making the tank in this manner, ive joints are dispensed with. To this frame, plates of the proper size and shape are applied, and thejoints made liquid-tight all round. It will thus be seen that there are but vtwo seams allround. .Y i

I have described and shown this as' a desirable way of making the tank', but I do not limit myself thereto, as joints might be made at thepoints L i c l, and then .the bottom would be made with fewer joints than in any oil-tank heretofore constructed.

The bottom of a tank, if constructed with the joints h z' k Z, would consist of inclinedplates or surfaces, extending from the point of `junetionfwith the sides to 'a central point, (see fig'. 2.) By such construction ,there 4would be no seam in the bottom except where the same joins the sides.`

A depressionor groove, d, is madein the bottom, (sce iig. 2,) which increases in depth as it approaches the side of the tank at the point where the faucet e enters it. It will therefore be seen that all the contents of the tank can be drawn ofi, and that the sediment will have but little chance to clog up the discharge-orifice of the tank, the same liaving'na free chance to escape.

C is a lining or filling of some iire-proof material or substance, placed outside they tank B. In thel present instance, the said filling is interposed between the tank B andthe enclosing case Afthe ensealing case being, of course, in cases where this iilling is to be used, made suiciently larger than thetank to admit of its introduction. This filling may be of any material suitable for the purpose, and applied in any suitable vway.

Should the enclosing ease -be made of wood, and get on fire, it may all be consumed, and yet the tank be protected. Should the enclosing case, on the other hand, be made of metal, the filling will prevent heat from injuring the tank, and should the fire-proof material be secured to the outside of the tank B, the same object will be gained.

It will be noticed that the cover oflthe tank is also provided with a fire-proof filling.

For'greater security, I will mention that the faucet may be provided with a screw-cap, and in such case, if the tank be iilledwith a highly-infiammable liquid, there would be less danger than with auordinary faucet.

I do not limit my invention to the construction of 'an oil-safe with this filling, as a'tank such as I have described can be made and used without it, and it may be used with or without the enclosing case.

A I am aware that an oil-safe, consisting of a metallic tank enclosed in a wooden case, is not new, the same being'shown in a patent granted to E. L. Allen, ou the v8th of May, 1866; but I wish it to be distinctly understood that the construction of the tank shown in that patent and in my present application -is entirely different.

The bottom of that tankis made like a hopper, the said bottom being constructed of fourr triangular-shaped pieces of metal, inclined to a central point, and united by four joints where the pieces are soldered together, and said bottom' is alsosoldered to the sides', making eight seams at the bottom. The discharge-orifice is at the centre of the bottom, a lead pipe connecting it with the faucet.' I have found, by practice, that with the Allen.

safe, (and I state this without any desire to disparage the invention of another party, but simply to show the advantages of my invention over that cne,`) the sediment clogs up the discharge-milice, andthat much leakage occurs, after alittle use, through the seams at the bottom-of the tank. Furthermore, the cost and labor of constructing thishopper-iike bottom are much more than with that in my tank.'

What I claim as my invention, and desire to secure by Letters Patent, is

1. An oil or liquid-tank, constructed without any joint at either or all of the points lettered L z' c Z in the drawing, substantially as herein specified.

2. An oil or liquid-tank, provided with a bottom composed of two inclined surfaces, andv provided with a depression at about the central point, substantially as and fortlrepurposes herein set forth.

4 3. The combination, with a tank constructed in either of the above-specified ways, of an enclosing case, of

wood or other material, substantially as herein specified.

4. The combination, with said tank foi containing oil or other iniiammable liquid, of some suitable {ireprooi` material, substantially as and for the purposes hereinspeciied.
