CRUDE-OIL BUR/NER.

Application filed July 18,1921, Serial No.r485,532. Renewed December 27, 1923.

To all whom it may concern;

Be it known that I, Gnonen ARBUTHNOTT SMITH, a subject of the King of England, residing at Ocean Park, county of Los Angeles,

5 and State of California, have invented certain new and useful Improvements in Crude- Oil Burners, of which the following is a specification. A

This invention relates to hydrocarbon i burners and more especially to crude-oil burners.

Its object is to produce a simple and inexpensively constructed device of this character which is adapted to be conveniently employed within an ordinary cooking stove, which is economical in the consumption of fuel and which is absolutely safe.

With these ends in view, the invention consists in the novel construction, arrangement and combination of parts hereinafter described and claimed.

In the accompanying drawings,- Figure 1 is a longitudinal vertical section of a burner embodying my invention shown in its preferred form and applied to a stove.

Fig. 2 is a plan view of the burner shown in Fig. 1. Fig. 3 is a transverse vertical section of a burner shown in a modified form,

said section being taken through 3-3 of F ig. 3o 4. Fig. 4 is a plan view of Fig. 3 and Fig.

5 is a perspective view of the burner illustrated in Figs. 3 and 4.

In said drawings, the numeral 5 designates a cooking stove having a fire box 6 and the usual holes, such as 7, in its top 8.

In carrying out my invention I provide a shallow pan 9 of a diameter less than that of the stove hole 7 to ermit its being inserted therethrough. Said pan is of the shape of an inverted truncated cone and is desirably provided about its upper edge with a flange or brim 10. Secured in circumferentia-lly spaced relations to the pan are hangers 11 which depend from a plate 12 of greater diameter than the hole 7 and is supported upon t-he stove top 8. Said pla-te constitutes the cover for said hole and the roof member of the burner.

The plate member in the preferred construction, Figs. l and 2, is of a truncated conical form with a marginal rim 13 which seats against the upper surface of the stove top.

An aperture 14 is provided in the plate member 12 through which fuel oil is poured into the pan for starting a lire or to replenish the samewhen in operation. Said aperture also yaords a means for' applying a flame of fire into the burner to start the burning of the fuel.

Air for vcombustion purposes is yadmitted into the interior of the burnerthrough dra-ft openings 15 provided in the sloping periph-- eral wall 16 of the roof member 12.

In the modified form, see Figs. 8, 4 and 5, the roof member 121 is in the nature of a plane plate having a substantially rectangular shape with a length and width somewhat greater than the diameter of the stove hole 7 and, similar to the member 12, is provided with a centrally disposed fuel supply aperture 141.

18 represents a slot provided in the plate 121 to accommodate a stove lifter of any well known type. In each of the illustrated embodiments of the invention, the pan 9 is disposed at a short distance below the respective plate so that the heat produced by burning oil in the pan will render the plate extremely hot for cooking and will serve to direct the flames against the stove top.

For operation a layer of porous material such as coal ashes or sand is advantageously placed in the pan and a small quantity of oil poured thereupon through the aperture 14.

`A convenient way to ignite the oil is to deposit a burning piece of oil-saturated paper through said aperture. hen the oil in the pan burns it produces a'fire which may be promoted or decreased by regulating a damper, not shown, in the smoke pipe 19 of the stove or, where a plane plate is employed as illustrated in Figs. 3 and 4, by shifting the burner horizontally so that the plate 121 will leave a draft opening of suitable size through the hole 7 at one side of the plate to admit air into the fire box for combustion purposes.

The pan by being suspended adjacent to the plate affords al combustion chamber between the plate and the pan with a relatively small opening above the brim' thereof for the intake of air to combine with the oil vapors and for the escape of the hot combustion gases principally in the form of flames. The

heat produced by the burning oil gases in the pan is sufficient to maintain the temperature therein considerably above that requisite for combustion. TWhen the fire becomes low additional fuel oil may be poured through the aperture 14 without any danger to the operator.

What I claiin, is,-

1. An oil burner, comprising a pan open at the top, a plate of greater diameter than the pan, said plate being of a substantially truncated conical shape, and means rigid with and depending from said plate to support the pan in parallel rela-tions therewith and afford an intervening space, said plate being provided with an oil-feed aperture located in approximately the axis of the pan, and with draft openings in the peripheral Wall thereof. y

2. In apparatus of the character described,

the Ycombination with a fire-box having a top Wall with a hole therein, of a burner coniprising a truncated conical shaped plate adapted to seat upon said top Wall at diainetrically opposite sides of the hole, said plate having draft openings in the sloping peripheral Wall thereof, a pan, and hanger elements secured to said plate and extending through said hole to support the pan Within the lire-box.

Signed at Seattle, Washington, this 6th day of July, 1921.
