HYDROCARBON BURNER Filed Nov. 17, 1927 2 Sheets-Sheet @www Patented Dec. 3l, 1929 imitan STATES PATENT loI-rica JAMES L. BREESE, JB., OF CHICAGO, ILLINOIS, ASSIGNOR TO OIL DEVICES COBIOMTION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS HYDnooARBoN BURNER My invention relates to adevice for burning hydrocarbons, which is particularly 4adapted for the burning, in heating plants,

A of a liquid hydrocarbon. One object of my 5 invention is to provide a simple and easily manufactured complete fuel supply and heating unit adapted for installation in any suitable heater. Another object is the provlslon of clamping means for sealing oil' the air in the ash pit door. Other objects will appear from time to time in the course of the speclcationand claims.

I illustrate my invention more or less diagrammatically 1n the 'accompanying drawi ings, wherein- Figure' 1 is a perspective view of my device, showing the heating unit withdrawn from lthe heater or stove; Y

Figure'2 is a vertical section ofthe heating` unit positioned within the heater;

igure 3, is a section along the line 3-3 of Figure 2;

-Figure 4 is an enlarged top plan view of the combination oil and gas inlet;

Figure 5 is a section along the line 5-5 of Figure 4; and

Figure 6 is a vertical section along the line 6-6`of Figure 5.

Like parts are indicated by like symbols throughout the speciiication and drawlngs.

It will be realized that I describe and illustrate a complete fuelv 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.

A generally indicates a heater of a well known type having the usual supporting legs A1, a flue escape pipe A2 and a fire dox door A3.

B indicates a fuel suppl and heater unit having a combustion mem er B1. The latter includes a bottom ortion B2 resting upon the bottom of the as pit A4 of the heater A, and provided with the upwardly projecting generally cylindrical wall B3 in communication with which is the longitudinal airl inlet passage B", which is braced by the member B5 to the wall B3. Said wall may be provided with indentations Bv for clearing the lugs A*s or other projections inside the ash pit opening;

Seated upon the upper edge of said wall is a mixing chamber having the bottom portion C which may be concavev as'shown and the upwardly projecting cylindrical side wall C1, which may be made of two parts C2 C secured together by the crimp C4. Cs are a plurality of large and small apertures penetrating the upper part C3 of the wall, ermitting air to enter the mixing cham er. Exteriorly projecting from the wall C1 is a circular flange C with a downwardly projecting ring C1 adapted to be seated upon the upper edge of the drum B3. C8 is a conic shaped split ring positioned inl the circular depression or groove C9 in the wall C1. l

D generally indicatesa gas and fuel inlet having a top portion D1 which may be hexagonalin shape, and has an annular channel D2 in its lower side. Projecting downwardly from the portion D1 and centrally located within said channel D2 is the conical ortion D8 associated with a downwardly ex nding stem D4 having an outwardly projecting flange D5 with a conical-shaped end portion D". As best illustrated in Figures 5 and 6 ,the flange Dl5 and conical end portion D1 seat in a correspondingly shaped depressed portion C10 centrally located and integral with the concave bottom C of the mixing chamber. D7 are a plurality of passages in the stem Df, extending from the fuel passage D8. D9 are a plurality of downwardly inclined gas outlet passages extending from the chamber D10 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 sidefoutlet. It is provided with a seat E2 adapted to receive the correspondingly shaped depressed portion C10. The member from the fuel passage E4 by means of a wall E2. E7 is a gas supply line communicating with the passage E5. As best vshown in Figures 4, and 6, gas for the ,necessary pilot 5 lights for igniting of the liquid hydrocarbon fuel has free access to the mixing chamber by means of thepassageE, tube D11 and assage D1o communicating with the gas outets D". The downwardly inclined flames of m the pilot lights will be in the direct path of the liquid fuel flowing through the apertures D7. Integral with the member E is a boss E downwardly projecting through the hole B7 located in the upwardly depressed 15 portion B2 of the bottom B2. E12 is an aperture in the boss E1o adapted to receive the locking pin E13, thus securing the mixing chamber to the air drum B3.

F indicates a fuel tank having a conical bottom plate F1. F2 is a fuel control valve v#responding to the action of the float F3 in theiioat chamber F4. Upwardly extending above the r'upper edge of the fuel tank F is the rotary stem F5 for controlling the flow '25 of liquid fuel through the valve F2. F6 is a cover. The float chambery F4 is provided with an outwardly projecting circular flange .F7 upon which is seated the fuel tank F, centered by means of the upwardly extending o flan .e F8 and held in place by the split locking ban F. Mounted in the fiange F7 at'either side of the float chamber are the supporting rods lF1o F10, having the adjustable base members F11' with locking screws F12.

Communicating with the float chamber F4 is the upwarly extending pipe G associated with the fuel line E2. As illustrated in Figures 2 and 3, vthe fuel line E3 and gas supply pipe E7 are positioned within the air. inlet assage B2 which may be supported by braces him or other suitable means. The fuel line E3 is provided with a control valve G1 havingr the upwardly protruding handle G2.

Figures 2 and 3 illustrate the heating unit j with the combustion member positioned withl in the ash pit A4. The usual ash pit door of the heater A has been removed and been replaced by the closure plate H cut away as at H1 to conform to the shape of the laterally projecting air passage B". H2 is a locking member, hinged as at H3 to the usual pin H4 provided for'the ash pit door. H5 H5 are spring members mounted on the member H2 adapted for frictional engagement with the plate H, pressure being applied by means of the screwthreaded stud H6 mounted in the heater A and penetrating the locking member H2 and the wing nut H7.

It is understood that the usual grating associated with the heater` A may preferably'be removed as shown, leaving free access to the combustion chamber A7.

It 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 vplant is of greatimportance.

Referring to the unit itself oil flows from the float chamber F4 along the line E3 to the elbow member shown in detail in Figures 4, 5 and 6. The elbow member also receives gas through the line E7.' Itv will be noted that the gas and oil ilow upwardly through the same member, although being supplied of course through different ducts to the bottom of the mixing 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 oil ducts.

In order to prevent the inow of air through the grate door, the grate door being removed, I provide the structure shown in detail in Figures 2 and 3 which includes the plate H, cut away as at H1 to conform to the air' passage'E, upon' which it may rest. In order to hold it against the edges of the grate door I provide vertical spring arms' H5 which are secured to the transverse strip H2, one end of which is hinged to the `normal pivot pin H2 of the ash pit door, whereas the other is secured at the opposite side of the door, fory example bythe screwthreaded stud He and the' ring nut H7. yielding pressure against the closure member H, which keeps it tightly sealed in place the pressure being applied particularly to the four corners of the plate.
