OIL Brianna.

Application filed August 17, 1925, Seria1 No. 50,662. Renewed February 14, 1927.

This invention relates more specifically to an oil burner designed to be operated under air pressure.

main object of this invention is to provlde a simple burner mechanism in which combustibility.

A still further object is to provide a burner construction in which the burner flames are efficiently controlled.

Other objects and advantages will be apparent from the following description, reference being had to the accompanying drawings forming a part of the specification, in-

which:

Fig. 1 is a central vertical section through the burner showing its oil and air inlet connections.

Fig, 2 is a plan view of the same.

Fi 3 is a cross section taken on line 33 of Fig. 1.

Fig. 4 is a diagrammatic view of the burner showinin dotted line the form of flames produced y the air deflecting means.

Referring now more particularly to the drawings, the burner preferably consists of a circular dish shaped cast metal body number 5 provided with a centrally disposed air inlet 0 ening 6, the under and upper surfaces of t e body member 5, around said opening being provided with circular flanges 7, 8, preferably cast integral therewith. Secured to flange 8, is an air inlet conduit 9 that leads to a blower of any preferred type (not shown) for supplying the burner with air to form with the fuel a combustible vapor, a butterfly valve 10 being mounted in the conduitto control the volume of air admitted to the burner during its operation.

Detachably mounted directly above the air inlet opening 6 of the burner is a circular disk deflector 11 concaved on its under face and provided with an annular bead 12 adjacent its edge.- Disk 11 is supported above 7 Y the air inlet opening by means of a plurality of studs 13, here shown as three in number, their lower ends being cut away on their sides to formabutments. In order to maintain the disk deflector in immovable relation,

tween the fuel tank and the burner by a suitable needle valve (not shown).

The operation of the burner will be clearly apparent from the following description. Fuel is admitted to the burner body or pan by gravity flow in the required quantity where it is ignited, the air delivered by the blower apparatus passing through the air inlet opening is deflected by the disk 11 downwardly against the body of oil in the body member or pan of the burner, the annular bead 12 directing the blast of air at such an angle to the oil that the two elements are thoroughly commingled to form a highly combustible gas or vapor. As the body member is of dish form the annular side wall will direct the flames of the burner in .cone shaped form or a compact mass, which is not desirable as such mass formation of the burner flames will not heat the fire pot of a furnace as efliciently as when the same are spread out or lengthened, and to this end the deflector disk 11 is provided with a plurality of apertures 17 around the central disk clamping bolt 14 to permit of a portion of the air passing through the inlet to pass through said apertures to spread the flames of the burner outwardly as clearly shown in the diagrammatic view of the drawings.

The burner as constructed has been found to be highly eflicient, almost perfect combustion taking place during its operation this being apparent from the entire absence of any gaseous odors. By arranging the air deflector directly above the air inlet to the burner so as to deflect the air downwardly into the body of oil in the burner, perfect atomization takes place utilizing every heat unit of the fuel, and producing a greater volume of heat from a given quantity of fuel than it has been heretofore possible to attain in burners of such type,

What I claim is:

1. A gas generator and burner com rising a burner pan having an air inlet supp y pipe connected thereto, a fuel supply pipe leading to said pan, and an air deflecting plate detachably secured to said pan above the air inlet opening adapted to deflect a portion of the air from the inlet supply downwardly against the fuel in the burner pan to vaporize the same, said deflecting plate having a plurality of openings therein forcontrollin the direction of the burner flames, an means to control the volume of air passing through said air inlet supply pipe.

2. A gas generator and burner construction comprising a shallow pan having curved side 'Walls, an air inlet and fuel supply pipes leading thereto, and an air'deflecting plate secured above said air inlet opening adapted to direct the air from the inlet pipe downwardly against the fuel in the pan to vaporize the same, said plate having air outlet openings formed therein for controlling the direction of the burner flames.

In witness that I claim the foregoing I have hereunto subscribed my name this 7th day of August, 1925.

JAMES A. KEN WORTHY.
