HYDROCARBON COOK-STOVE.

SPECIFICATION forming part of Letters Patent No. 621,959, dated March 28, 1899.

Application filed March 30, 1898.

To @ZZ whom it may concern:

Be it known that I, DANIEL W. COLE, a cit-- zen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Hydrocarbon Cook- Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention7 such as will enable others-skilled -in the art to which it appertains to make and use the same.

This invention relates to an improvement in hydrocarbon cook-stoves, its object being to provide a stove of peculiar construction capable of utilizing waste heat andso disposing the same as to insure thorough heating at a minimum cost and providing means whereby all odors, &c., pervading the combustible gas are destroyed before reaching the outer atmosphere. To attain these desired objects, I provide a stove having two or more compartments or chambers, one 0f which contains the oven, which is constructed so as to permit of the passage of air around all sides thereof, while the other compartments, which communicate with the large or heated chamber inclosing the oven, contain a heating apparatus of peculiar construction. Said heater is composedof a retort or chamber adapted to receive the unburned gases and from which they pass upward through a coil of pipe, then downward to a point immediately beneath said retort, where they are consumed, thereby heating both the surrounding atmosphere and the unconsumed gases passing through the retort, resulting, as will be obvious, in the destruction of all odors, &c., found in hydrocarbon gas of this character. Suitable iues are also provided, whereby the circulation of hot air Within the stove is readily and conveniently regulated.

As an additional feature of the invention a gas burner or jet for illuminating purposes is provided, which is connected to the heater, as will be more fully hereinafter described.-

In the accompanying drawings I have shown the preferred form of my invention.

In said drawings, Figure l is a perspective view of the stove. Fig. 2 is a top plan view thereof with the top removed. Fig. 3 is a versanti no. 675,765. (No mano tical section on line 3 3, Fig. 2. Fig. tis a vertical section on line 4 4:, Fig. 2. Fig. 5 is an elevation of the heater detached, and Fig. 6 is an enlarged Vertical section therethrough.

Referring to said figures by letters of reference, A is the base of a stove, supporting thereon near one end the casing B of the large or heated chamber, within which is held or constructed an oven B, which projects thereinto, preferably resting upon slight supports 6o o at each corner, and thus permitting the free passage of hot air around it, as will be obvious.V

Upon the base or stand A, formed on or secured to the side of the casing B, are one or more heating-chambers C C, containing the heating apparatus hereinafter described. These chambers C C are preferably circular in form and are connected, as shown, forminga chamberorshaftD, communicating with 7o chamber B by means of a flue d at the bottom thereof and to chambers C C by means of openings or lues CZ', preferably at the top, as shown. Additional flues c c are provided A which permit the free and direct passage of air from the heating to the heated chambers, said fines being regulated by slides c', as shown, said slides traveling in grooves c2 and operated, preferably, by rods or arms secured thereto and projecting from the side of the 8o casing B. Within each of the heating-chambers C is placed ahydrocarbon-heater, as shown. Said heater consists, essentially, of a conductingpipe E, adapted to lie along the under surface of the stand A and suitably connected to a gas-supply. Said pipe E projects upward vertically at a point in the center of the heating-chamber C and opens into the lower end of a closed retort or chamber F, substan- 9o tially funnel-shaped in construction. From the center of the upper end of the retort F projects a second pipe G, which circles upward,forming a coil H, and nally turns down to a point directly under retort F, terminating in a burner or tip g. This pipe andthe retort F are constructed of suitable non-fusible metal possessing good heat-conducting qualities. Projecting upward from the top of retort F is a third pipe I, which extends to any roo desired point above the top B2 of the stove by passing through a perforation formed therein. At the end of this pipe is an ordinaryilluminating gas tip or burner. The flow of gas therefrom is regulated by a cock or stop Gas is admitted to the retort- F and coil H by means of the pipe E, which is connected to the supply. Passing through the pipe II downward the gas is ignited as it flows from the tip g, the iow therefrom being regulated and controlled by a cock or stop, as shown. The [lame thus produced is supported bythe atmosphere entering the openings C2 or doors C C in the sides of the heating-ehambers and heats not only the surrounding atmosphere, but the retort Fand coil H as well. All gas escaping from the burner necessarily passes through the retort F and is thoroughly heated, thus resulting in the destruction of all odors, the., contained therein, as well as increasing the heat derived therefrom. This construction also permits of a great saving of heat, as will be obvious, owing to the thorough means for superheating the gas as well as to the distribution of the heat conducted by the coil H through the atmosphere.

The simplicity of construction and thoroughness of operation of my device render the same most desirable for use.

In the foregoing description I have shown the preferred form of my invention, but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

l. In a hydrocarbon cook-stove, the combination of a heated chamber containing an oven around which hot air circulates, the heating-chambers, hydrocarbon -retorts arranged in said heating-chambers, and the intermediary chamber: having openings communicating with said heated chambers at their upper ends, an opening opposite said latter openings communicating with said heated chamber atits upper end, and still anl other opening or flue at its lower end communicating with said heated chamber at its bottom, substantially as set forth.

2. In a hydrocarbon cook-stove, the combination of a heated chamber containing an oven around which hot air circulates, the heating-chambers having valves, openings or flues at their upper ends communicating with said heated chamber at its upper end, hydrocarbon-retorts arranged in said heating-chambers, the intermediary chamber having openings at their upper ends communicating with said heating-chambers at their upper ends, an openin g opposite said latter openin gs, conimunica-ting with said heated chamber, at its upper end, and still another opening or luc at its lower end communicating with said heated chamber at its bottom, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
