SPECIFICATION formingpart of Letters Patent No. 729,115, dated May 26, 1903. Application filed February 26, 1908. Serial No. 145,237. (No model.)

To all whom, it may concern.-

Be it known that I, CORTLAND BALL, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

The object of my invention is to provide means whereby a more perfect combustion of hydrocarbon oils, either crude or refined, may be obtained free from soot or smoke without the employment of preliminary spraying or vaporizing devices. I accomplish this result by means of wood-ashes and the admixture of air and steam into flame, as hereinafter described, and set forth in the claims forming a part of this specification.

Another object of my invention is the provision of a hydrocarbon-burner which will be the embodiment of simplicity and durability, which can be produced at a low price, which can be readily and easily applied, and which will be efficient and practical in every particular.

With these objects in view my invention consists of a hydrocarbon-burner embodying novel features of construction and combination of parts, substantially as herein disclosed.

Preliminary to a more detailed description of my burner it may be well to state that itis adapted to fit within the fire-box of any ordinary cook or heating stove, and it is to be understood that a tank or reservoir for the oil is to be located at any desirable place and at a height to cause the oil to flow to the burner through the oil-supply pipe connecting. It is also to be understood that a tank or reservoir for the water-supply used in generating steam is located, preferably, at the rear end of the stove, with sufficient elevation to cause the water to flow readily into the steam-generators through a connecting pipe. Valves are to be connected to the pipes to control and regulate the flow of oil and wa ter into the burner and steamgenerators. When a burner is put into a stove, it is be understood that fire-clay, brick, or some other suitable foundation is to be placed in the firebox, so that the burner may be secured in position by the flanges resting thereon. Then mortar made of fire-clay must be put all around it, so as to insure that all air drawn into the stove by the draft of the flue will pass by way of the air-inlet into the burner. This air will be deflected, by means of a deflector, into the flame, with which the steam and air will mix, producing a complete and perfect combustion and a flame of intense heat.

In the accompanying drawings, Figure l is a perspective view of my h ydrocarbon-burner, having some of the interior portions broken away, so as to more clearly show theinterior construction. Fig. 2 is atransverse sectional View showing air and oil inlets. Fig. 3 is a detail view showing one way by which the steam generators may be secured to the burner-case.

In the drawings the same characters refer to the same parts in all the figures.

In the fire-box of the stove I place the burner-case 1, having the supporting ledge or rim 2 and opening 3 in the bottom, through which air is admitted to the burner and directed into the fire by the deflector 4. A wall 5, formed integrally with the burner-case 1, forms with it and the shield 6 the combustionchamber- 7. The vertical wall of shield 6 separates the combustion-chamber 7 from the distributing-chamber 8, while the horizontal wall covers and incloses said chamber 8, thus preventing the oil from being ignited before it passesinto the combustion-chamber 7 through the proper passages, as indicated by the arrow. The vertical wall of shield 6 rests upon the bottom of case 1 and is provided with openings at a, through which the oil is admitted to combustion-chamber 7. Upon the floor of distributing-chamber 8 and between the oil-inlet 9 and feeder-openings a a is placed a rib or dam 10. One or more steam-generators 11 are secured to the burner-case 1 by means of screw-plu gs 12. The generators are connected each to the other by means of pipes 13. The water-supply pipe 14, as shown, is connected to the center generator 11.

16 are pipes that lead from the end generators to the discharging steam-pipe 17, which is provided with small vent-holes 18, which are arranged at predetermined distances apart and are so directed that theescaping steam will be discharged directly into the fire. By this form of constructing a steam-gener- 15 and ating device the steam will be more evenly discharged into the fire than it would be it the steam entered the discharging steam-pipe 17 at only one end. This is a very important feature in the construction of my burner. Plate 4: is so combined with the burner-case 1 that it forms a deflector whereby the air necessary to combustion is so directed upon the fire as to cause the most effectual heatproducing combustion that can be obtained.

I fill combustion-chamber 7 with wood-ashes level with the top of shield 6, as shown. I have found by thorough test under actual working conditions that ashes made from hard wood, preferably hickory, will produce a much better result than can be obtained with ashes made from coal or any finely-pulverized capillary substance, and while the reason for this result is not fully understood still I'believe it is wholly due to the action of the alkali contained in the ashes. I have also found that by removing the ashes occasionally and replacing them with fresh ashes very gratifying results are obtained. I have found, too, that the volume of heat can be momentarily greatly increased by taking a poker and stirring up the ashes occasionally.

In starting a fire the valve in the oil-supply pipe is to be opened to allow oil to flow into the oil-distributing chamber, and when it has passed out through the feeder-openings into the. combustion-chamber, so as to permeate the ashes sufficiently, then a piece of paper or a match may be lighted and placed on the top of the ashes, when it will be ignited instantly. Then the valve in the water-supply pipe may be opened just for a moment to allow the steam generators to partially fill with water. Then the valve should be closed until the steam begins to generate, when it may be gently opened again.

Having thus fully described my hydrocarbon-burner, I claim 1. In a hydrocarbon-burner the combination of a case, having an oil-distributing chamber formed by a wall therein, an oil-supply pipe connected with said chamber, a rib or dam in said chamber to distribute the oil to the combustion-chamber, a shield to cover said distributing chamber, a combustion chamber filled with wood-ashes, an air-inlet adjacent thereto and a deflector located on top of burner-case directly over the air-inlet substantially as shown.

2. In a hydrocarbon-burner, the combination of a case, having an oil-distributing chamber formed by a wall therein, an oilsupply pipe connected with said chamber, a rib or dam in said chamber to distribute the oil to the combustion-chamber, a shield to cover said distributing-chamber, a combustion-chamber filled with wood-ashes, an airinlet adjacent thereto, a deflector so placed as to direct the air into the combustion-chamber, and one or more steam-generators connected with a steam-discharge pipe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CORTLAND BALL.
