VIMPRQVEMENT m COAL-OIL, s'rov'ss.

Specification forming part of Letters Patent No. 60,680, dated January 1, 1867.

To all whom it may concern:

Be it known that I, FRANKLIN H. BROWN, of Chicago, in the county of Cook and State of Illinois, have invented a new-and useful Improvement in Goal-Oil Stoves; and I do hereby declare and make 'known that the following is a full,clear, and exact description of the same, reference being had to theacconn panying drawin gs, and the letters and figures marked thereon, which form part of this specification.

My invention relatesto a novel and convenient arrangement for a stovein which kerosene or coal oil may be used as fuel, and whereby cooking, boiling, or baking can be readily accomplished without heating up the room or house, thus rendering it a very desirable artiole, especially for summer use.

To enable those skilled in the art to understand how to construct and use my invention,

' I will proceed to describe'its construction and operation, making reference in so doing to the aforesaid drawings, in whieh- Figure 1 represents a vertical central section of my-invention. Fig. 2 is a plan or top view thereof, the boiler G being removed;

Fig. 3, a detached section of the oil-reservoir and burner; Fig. 4, a detached top view of the burner. Figs. 5 and 6 are, respectively, sectional and top views of a varied form of burner; and Fig. 7 represents an oven attachment, which sits in the place of the boiler G in Fig. 1.

Similar letters of reference in the several figures indicate the same parts of my invention. I

A represents a circular plate of suitable size, generally intended to be ofthe. same diameter and shape asthe body of the stove, which is supported upon the legs Q, to which the plate Ais also attached. The said circular plate has an opening at the center, around which the walls of the stove B C F extend, of the configuration and arrangementshownin Fig. 1.

D represents a circular plate, arranged horizontally at the joint where the inclined or funnel-shaped part of the stove, O, joins the ver-,'

In this plate are made a series of apertures, provided with griddles d, in which, when desired, pots or kettles, saucepans, and the like, may he placed, as shown.

tieal' wall F.

bars; and in the In a suitable central aperture there is suspended a cylinder, E upon the rod e,asshown in Fig. 2, the lower end of which cylinder merges into afunnel, as shown, which has the effect to disper e the heat around the same, and bring it in contact with the exterior series of griddles, 01, when desired. By i nvertingsaid device E, and arranging it as shown by the dotted lines in said Fig. 1, the heat is concentrated beneath the central aperture, whereby very rapid heating or boiling may be effected.

Upon the top of the stove is arranged, as shown, a boiler, G, surrounded by a casing, H, which fits, as shown, within and upon the stove, forming a heat passage up between the boiler and easing, as shown, suitable apertures being provided at the top, (marked h,) through which the heat passes out.

Instead of the boiler G, an oven, as shown in Fig. 7, may be used for baking; or a drum for radiating heat may be used, if desired.

Upon the shelf A a vessel of water, P, may be arranged where it will be heated; or anything whieh it is desirable to keep warm may be set thereon for that purpose.

J represents the reservoir containing. the kerosene or oil, and is connected with a pipe, K, with the burner L, arranged, as shown, beneath the central opening in the shelfA, hereinbefore mentioned.

The quantity of fue or oil supplied to the burner is regulated by tne following-described arrangement: M represents a close tube passing down through the reservoir, through which a narrow longitudinal slot (marked. m) is cut, as shown. Inside of 4 screw, plug, or valve,'working up and down in said tube, (marked N,) which projects from the top, and'is provided. with a suitable'dcviee for turning said plug N, to raise and lower the same, thus lessening or increasing the outlet M for the oil, as desired.

L represents an annular burner, having an air-passage up through the center, as clearly shown, said burner being in form an annular trough, into which the oil is fed, as shown.

Across said trough, near the bottom, as shown at a, is a partition, perforated, or composed of space below the said perfo- ASSIGNOR r0 HIMSELF AND- said tube is arranged a rated plate is placed wicking or cotton, or other suitable fibrous or porous material, while the space above said plate is filled with sand,iron filings, or some other porous or fibrous incombustible material as may be preferred. The said passage below the perforated plate a is designed to facilitate the equal and uniform distribution of the oil beneath the entire burnin g-surface, and may be filled, as above mentioned, with wicking or other similar :natefial when the lighter hydrocarbons are used a burning material, andin other cases may be left free.

Instead of having an annular burner with a central opening, the burner may be constructed as shown in Figs. 5 and G, or in any other form, provided there are suitable .air-' passages up through the same to supply oxy-. gen to the flame and supportthe combuslieu of the oil. The oil saturates the mass below and passes up through the plate a into the iron filings, and is ignited when desired, the heat passing down through the filling and vaporizing the oil, and thus produces a flame from the gas or vaporized oil thus obtained or produced.

The plug N may, when desired, be turned down far enough to cut off the oil wholly from the burner, the lower end of the plug resting in that case a )011 the valve-seat n.

R represent s a portion of the wall F, hinged at r, so as to open as a door, to render the interior of the stove accessible when the boiler I G is in use, or the even, if desired. The said door R is provided with a. latch, which enters a catch, 6, and thus secures the door in place.

Having described my invention, I will now proceed to specify what I claim and desire to secure by Letters Patent.

I claim-- 1. The reversible heat-deflector E, arranged and operating substantially as and for the purposes specified and shown.

2. In combination with astove constructed substantially as herein described, Lclaim the burner L, provided with a passage beneath the perforated partitions a, to effect an equal diffusion of the oil through the burner, when arranged and operating substantially as set forth.

3. I claim, in combination with a burner, L, constructed as described, the reservoir-J, the tube M, provided with a slot, m, and the plug N, operating substantially as and for the pur- I poses set forth.

' 4. I claim the combination of the deflector E and plate I), when arranged within the stove substantially as described.

5. In combination with thestove, constructed substantially as described, I claim the plate A and passage B, when arranged substantially as and'for the purposes set forth.
