JAMES I. SLOAN, OF KANSAS CITY, MISSOURI.

OIL-BURNER.

Application filed September 24, 1912.

To all whom it may concern:

Be it known that I, JAMES I. SLOAN, a citizen 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 Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to oil burners, and has for its principal object to provide a device of that class for use in stoves, or turnaces, and wherein oil supplied to the burner is spread throughout an extended area in order to secure proper vaporization, and wherein the oil vapor is mixed with fresh air to produce etlicicnt combustion. In accomplishing these objects, I have provided the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein Figure I is a perspective view of a burner constructed according to my invention, a part of the top burner plate being broken away for better illustration. Fig. II is a central, vertical section of the burner, and the fire bowl of a stove to which it is applied. Fig. III is an inverted, perspective view of the top plate of a burner.

teiterring more in detail to the parts: 1 designates the bottom plate or bowl of the burner, which is usually mounted on a fire brick base 2 in the fire bowl 3 or an ordinary stove or furnace and completely covers the grate at, in order to exclude air from the burner and upper portion of the fire bowl. The burner bowl 1 has an upturned, pcriphcral flange 5 and its bottom slopes upwardly and inwardly to a central collar 6 which projects above the face of the plate and has a lower portion 6 depending from the bottom thereof into an aperture 7 in the fire brick base 2.

8 designates a diaphragm plate which is supported from the base by legs 9 and has a central boss 10 located over the collared aperture 11 of the base plate and a depending rim flange 12 spaced from the base plate to form an annular port 13. The top of the diaphragm plate is inclined downwardly and outwardly toward the periphery, and

has a central boss 14 provided with edge notches 1.5 tor spreading 011 over the in clined top, as will presently be described.

Extending upwardly through the collared aperture 11, in the base plate, is a supply pipe 16, of such exterior diameter that it forms an annular space within the collar, through which air may enter the burner beneath the diaphragm plate and pass through the annular port therearound to mix with the fuel vapor. The upper end of the supply pipe is threaded into an opening 17 in the diaphragm plate, but does not project entirely therethrough, the upper portion of the opening forming a port through which the fuel oil may be delivered on the inclined top of the diaphragm to flow thcreover, so that it may mix with the intake air to provide a suitable fuel.

In order to properly spread the incoming oil, I provide the diaphagm port with a float 18, comprising a convex body which is adapted to seat over and close the top of the port, and having a stem 19 which hangs into the port and, preferably, a short distance into the supply pipe, in order to guide the float and retain same in the mouth of the port, the upper edges of the port being provided with corrugations 20 through which the oil may low when the float is seated on the top of the port. It is apparent that with a strong flow of oil the Heat may be lifted sufficiently to allow the oil to pass through the port, but when the pressure is reduced, the float will again drop to its seat.

21 designates a cover plate, of greater diameter than the diaphragm, and provided with depending concentric rings 22 which support the cover from the diaphragm and have notches 23 through which oil delivered through the intake port in the diaphragm may pass as it flows down the inclined top of the diaphragm. The portion of the cover outside of the outer ring is of greater width than the portion between the inner and outer rings, as it is in the outer space that the oil is vaporized, and the central portion of the cover is concavcd upwardly over the diaphragm boss in order that the cover rings may seat on the diaphragm and a space is provided above the boss through which the oil may flow.

In using the burner, presuming the parts to be constructed as described, and assembled as illustrated, in an ordinary furnace the oil is first turned on through the supply pipe, and, rising through the pipe, is delivered onto the diaphragm boss over which plate having central apertures of different diameter, a cover plate having concentrlc it flows onto the top of the diaphragm to the edge thereof, passing through the notches in the edge of the boss and in the bottom of the cover rings, so that it is distributed evenly throughout the top of the diaphragm and passes over the edge thereof in a thin film. As the fuel oil passes up through the supply pipe, fresh air passes up through the aperture in the fire brick base and through the collar of the base plate of the burner and is deflected laterally by the diaphragm, rising around the edges of the latter and mixing with the oil to form a combustible vapor, which, when ignited, burns beneath the edge of the cover plate and coming in contact with the cover plate insures practically complete combustion, owing to the fact that the vapor after con tact-ling the cover plate is deflected back into the flame and must pass therethrough in order to-reach the edge of the cover plateand escapes up through the fire bowl,

aving thus 1 described my invention, what I claim as new therein and desire to secure by LettersPatent, is i 1. In an oil burner, a base plate having a central opening, a diaphragm supported on and spaced from the base plate and covering the opening, said diapl' agm having an opening therein above the base opening, a fuel supply pipe projected through and spaced from the sides of the base opening and fitted snugly within the diaphragm opening, and a cover plate having depending notched rings supporting same on the diaphragm.

2. In an oil burner, a base plate having a central opening, a diaphragm supported on and spaced from the base plate and covering the opening, said diaphragm having an opening therein above the base opening, a fuel supply pipe projected through and spaced from the sides of the bas-eopening and fitted snugly within the diaphragm opening, said diaphragm having a boss on its upper portion surrounding the opening and provided with notches in its outer edge, and a cover plate'supported on and spaced from the diaphragm.

3. An oil burner comprising a base memher, having an edge flange, and an inwardly and upwardly inclined upper surface, a diaphragm having a depending peripheral flange and having legs supporting same from the base plate whereby the peripheral flange is spaced from the inclined upper surface thereof, the diaphragm and base rings, one of which is adapted for supporting the plate on the diaphragm and both having notches through which fuelfiowing over the surface of the diaphragm may pass,

and a supply pipe extending into the opening 1n the base member into the opening in the diaphragm,- whereby fuel is dellvered onto the top of the diaphragm and air de'' livered around the supply pipe to the space between the diaphragm; an base plate.

at. An oil burner comprising a base member having a central 0- enin a dia hra' m.

supported on the base member and having a central opening, a supply pipe extending through the base openlng and into the diaphragm opening, and a fioat seated in the upper mouth of the diaphragm opening and having a loosely pendent stem suspended into the diaphragm opening.

5. An oilburner comprising a base plate, having a central opening, a diaphragm seated on and spaced from the base plate and having a central opening and notches in the upper mouth of the opening, a cover plate supported on the diaphragm, a convex float loosely seated in the upper mouth of the diaphragm opening, and having a stem depending into said opening, and a supply pipe extending through the base opening into the diaphragm opening.

(3. The combination with a fire bowl, pro vided with an opening, an apertured burner base seated on the bowl base and having a central opening, a collar on the burner base depending into the bowl base and having an upwardly projecting portion, a diaphragm seated on the burner base and having a central opening, a supply pipe projecting through the bowl base into the diaphragm opening, and a cover plate on the diaphragm whereby oil. is delivered onto and flowed over the diaphragm and air'is admitted- JAMES I. SLOAN.
