UNITED STATES PATENT OFFICE.

ADELBERT M. BRAINARD, OF CHICAGO, ILLINOIS.

HYDRDCARBON-GAS STOVE.

SPECIFICATION forming part of Letters Patent No. 275,127, dated April 3 1883.

Application filed March 11, 1881. (No model.)

T 0 all whom it may concern Be it known that I, ADELB-ERT M. BRAIN- ARD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hydrocarbon- Gas Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to the class of vaporburning stoves or heaters provided with a reservoir for liquid hydrocarbon, a generator, and burner with connecting-pipes, and has for its object to render the apparatus more compact, convenient, and safe, and in particular to adapt to this class of stoves the method of carrying the liquid to the generator by airpressure without increase, but rather with a diminution, of peril in so doing from the change made in the location of the liquid-reservoir.

To this'end the invention consists in the combination of parts hereinafter specified, arranged in a particular manner, as set forth, and as indicated in the appended claims.

In the drawings, Figure 1 is an end elevation ofthe apparatus usually called and herein referred to as a hydrocarbon-gas stove, and Fig. 2 is a side elevation of the same, both figures showing my improvement.

The same letter indicates the same part in both figures.

A is the stove top or table, of which A A are thelegs or supports.

B B may represent the gas generating and burner devices of the stove, which devices will be herein designated burners. They are here shown as of a peculiar form; but they may be of any desired or approved form or construction for all purposes of this invention.

G represents the main pipe, which supplies liquid hydrocarbon to the burners, and G G are the branches leading to the several burners.

A is a horizontal shelf supported from the legs A.

Ris the reservoir for the liquid hydrocarbon. Said reservoir is here shown as resting on the shelf A but it may be in any other suitable manner supported rigidly below the top A or by the legs A of the stove. Said reservoir is preferably made of east-iron and in a single piece, or nearly so. It has a screw-capped opening, R, discharging into the reservoir below .the top, by which it may be nearly but not entirely filled, and the main pipe Gr enters it by a close joint. Said pipe terminates near the bottom of the reservoir or tank, 1%, as shown by dotted lines in Fig. 2, If secured between the legs A, as shown, the reservoir It is clearly protected from injury or disturb ance.

P is a pump, preferably resting on the tank R, and communicating therewith by means of a pipe, 1 provided with a three-way cock, P which allows air to be forced from the pump into the tank, and also allows the air to escape from the tank at the cock when properly turned for the purpose.

P is a hand-lever for the pump, pivoted at one end to one of the standards A of the stove-frame, and also pivoted to the piston-rod p of the pump P. Its free end is in form and position convenient to be seized by the attendant. Valves G and G in pipe G cut off the flow of liquid to the several burners.

in this class of stoves it has been the usual practice heretofore to support the reservoir at a-considerable elevation above the stove-top and burners for the purpose of obtaining a suitable head to give a proper flow of liquid to the" burners. of removing the reservoir to a safe distance from the flame of the burner, said reservoir has been'generally raised to a much greater height than is necessary to produce the flow required.

Perhaps for the further purpose The support of such elevated supply-tank has side the limits of the stove-frame, it is more liable to be overturned, fractured, or loosened in its connections than in its former elevated place. In the construction shown, wherein the reservoir is placed between the legs of the frame, the latter serves as a guard or protector, and il' additionally secured, so as to be essentially rigid with the stove-frame, the reservoir cannot be overturned without overturning the 4 stove. In the construction here shown these objections are removed.

'When the stove is to be used the operator turns the cock P to give communication from the pump P to the reservoir R, and by one or more movements of the lever P compresses air in said reservoir above the contained liquid, so as to force the liquid to the burners. The cock is then turned to retain the air so compressed. If an attempt is made to fill the reservoir while the burners are alight, the first step to such operation-namely, opening the inlet R-releases the pressure, and the flame at the burners is instantly extinguished. hen the use of the stove is discontinued the cock P is turned to allow the compressed air to escape from the tank, whereupon the liquid in the pipes G and G flows back to the reservoir, whence it cannot escape, except when again expelled in the further use of the burners under the control of the attendant.

By arranging the inlet R to discharge below the top of the reservoirs, and thus at all times insuring an air-space above the liquid therein, a sufiicient quantity of air maybe compressed above the liquid immediately after filling the reservoir to force all of the liquid to the burners with a comparatively uniform pressure without again operating the pump.

Instead of a screw or other cap for the inlet R, a cock may be employed, as being better adapted to tightly close the same against the escape of air.

I am aware that it is not new to raise liquid to a burner from a tank below the level of the- I'am aware that airpressure has been emreservoir arranged within and supported by the 7 frame, an air-pump, a pipe arranged to receive from the air-pump and to discharge into the reservoir, a valve in said pipe accessible to the operator, and a valved pipe leading from the reservoir to the burner, substantially as described, and for the purposes set forth.

3. In a hydrocarbongas stove, the combination, with the stove-frame and an elevated burner or burners, of a reservoir for hydrocarbon liquid, located wholly beneath the burner, said reservoir being supported by the frame, and provided with an inlet for the hydrocarbon liquid, located ata considerable distance below the top, so as to have a relatively large airspace above the liquid therein when fully supplied, means for compressing air into said airspace, means for retaining the air when so compressed, and a pipe leading from the bottom of the reservoir to the burneror burners provided with suitable cook or cocks, whereby sufficient air may be compressed and retained in the reservoir when fully supplied with liquid to force all of said liquid to the burners ata substantially uniform pressure.

4. In the hydrocarbon-gas stove described, having the cast-iron frame A A, elevated burner or burners B, reservoir It, pump P, and the connections described, the reservoir and pump rigidly secured to the frame beneath the top A, and between the legs A, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

ADELBERT M. BRAINARD.
