HYDROCARBON BURNER Filed Dec. 5l, 1927 Patented Apr. l, 1930 UNITED STATES PATENT ori-ICE JAMES L. BREESE, JR., OF CHICAGO, ILLINOIS, ASSIGNOR TO OIL DEVICES CORPORA- TION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS HYDROCARBON BURNER Application led December 31, 1927. Serial No. 243,782.

My invention relates to a device for burning hydrocarbons, which is particularly adapted for the burning, in heating plants, of a liquid hydrocarbon. One object of my invention is the provision. of a combination gas and fuel inlet for the mixing chamber of a hydrocarbon burner. Another object is the provision of combined fuel inlet and securing means, adapted to aid in positioning and securing the burner assembly. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawin s, whereinigure l is a vertical' section of the heating unit to which my invention is applied;

Figure 2 is an enlarged top plan view of the combination oil nd gas inlet;

Figure 3 is a section along the line 3 3 of Figure 2; and

Figure 4 Vis a section along the line 4 4 of Figure 3.

Like parts are indicated by like symbols throughout the specification and drawings.

It will be realized that I describe and illustrate a complete fuel supply and burner unit which is adapted to be used with any suitable heater, the combustion member of the burner being for example placed within the ash pit of a coal burning heater.

generally indicates a heater of a well lrnown type having the usual supporting legs B indicates a fuel supply and heater unit having a combustion member B1. The latter includes a bottom portion Bresting upon the bottom of the ash pit A* of the heater A, and provided with the upwardly projecting generally cylindrical wall B3 in communication `:with which is the longitudinal air inlet passage B, whichis braced by the member B5 to the wall B. 1

Seated upon the upper edge of said wall is a mixing chamber having the bottom portion C which may be concave as shown and the wardly projecting cylindrical side wall 1, which may be made of two parts C2, C secured togetherby the crimp C1. C are a plurality of large and small apertures pene.y

trating the upper part Cs of the wall, permitting air to enter the mixing chamber. Exteriorly rprojecting from the wall C1 is a circular iiange C with a downwardly projecting ring C7 adapted to be seated upon the upper edge of the drum B3. Cs is a conic shaped split ring positioned in the circular depression or groove C9 in the wall C1. D generally indicates a gas and fuel inlet having a top portion D1 which may be hexagonal in shape, and has an annular channel D1 in its lower side. Projecting downwardly from the portion D1 and centrally located within said channel D1 is the concial portion Ds associated with a downwardly extending stem D4 having an outwardly projecting flange D5 with a conical-shaped end portion D". .As bestillustrated in Figures 3 and 4 the ange Ds and conical end portion De seat in a correspondingly shaped depressed portion C1o centrally located and integral with the concave bottom C of the mixing chamber. D7 are a plurality of passages in the stem D1', extending from the fuel passage D1. D are a plurality of downwardly inclined gas outlet passages extending from the chamber D1 above the tube or pipe D11 screwthreaded into the member D as at D12. The other end of said stub pipe is threaded into the member E as at E1. The member E is an elbow with a side outlet. `It is provided with a seat E adapted to receive the correspondingl shaped depressed portion The mem er E kand member D are secured to the bottom C ofthe mixing chamber and held in place by means of the tube D11, to which they are screwthreaded.

E1 is a liquid fuel pipe screwthreaded into the member E, communicating with the fuel passage E. In line with the lower open end from the fuel passage by means o a wall E.` E' is a. gas supply line communicating with the passage E. As best shown in Figures 2, 3 and 4, gas for the necessary pilot lights for igniting of the liquid hydrocarbon fuel has free access to the mixing chamber by means of the passage E, tube' D11 and passa e D1 communicating with the gas outlets The down .vardly inclined llames of the pilot loc lights will be in the direct path of the liquid fuel flowing through the apertures D7. Integral with the member E is a boss E10 downwardly projecting through the hole BT located in the upwardly pressed portion B of the bottom B2. El.2 is an aperture in the boss E10 adapted to 'receive the locking. pin E13, thus sspuring the mixing chamber to the air drum F indicates a fuel tank having a conical bottom plate F1. F2 is a fuel control valve responding to the action of the float F3 in the float chamber F. Upwardly extending above the upper edge of the fuel tank F is the rotary stem Fs for controlling the flow of liquid fuel through the valve F2. F is a cover. The float chamber F* is provided with an outwardly projecting circular iiange F7 upon which is seated the fuel tank F, centered by means of the upwardly extending flange F8 and held in place by the split locking band F. Mounted in the flange F7 at .either side of the float chamber are the supporting rods F1 Fw, having the adjustable base members F11 with locking screws F12.

- Communicating with the float chamber F* is the downwardly extending pipe G associated with the fuel line E3. The fuel line E3 is positioned within the air inlet passage B4r which may be supported by braces B1 or other suitable means. The fuel line E3 is provided with a control valve Gr1 having the upwardly protruding handle G2. If desired the gas line E7 may also be positioned within the passage Bf although it is not in detail so shown. y

VIt will be realized that whereas I have shown a practical and operative device, nevertheless many changes might be made in size, shape, number and distribution of parts without departing from the spirit of my invention. I therefore wish my drawings and description to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my specific description and showing.

The use and operation of my invention are as follows:

The heater unit herein shown may beapplied to any heater, for example a coal burning heater, bymerely lifting off the ash pit door and removingthegratesandinsertingthe mixing chamber. This ready conversion of a coal burning plant to an oil burning plant is j of eat importance. eferring to the unit itself oil flows from the float chamber F4 along the line Es to the elbow member shown in detail in Figures 3 and 4. The elbow member also receives gas through the line E. It will be noted that the -gas and oil il'ow upwardly through the same member, although being supplied of course through different ducts to the bottom of the mlxing *chamber` The gas jets which pass through apertures D incline downwardly into the path of delivery of the oil through the passages D7, the gas jets being vertically aligned with the oi ducts.
