CHRISTIAN" BACKINGER, OF SEATTLE WASHINGTON.
HYDROCARBON-BURNER.
To all whom it may concern:
Be it known that I, CHRISTIAN Biwiuxmcn, a citizen ot the United States, residing at Seattle, in the county of King and State oit' Washington, have invented certain new and useful Improvements in Ilydrocarbon- Burners, of which the following is a specitication.-
This invention relates to means for burning hydrocarbon oils as fuel in stoves, ranges or furnaces.v
The especial object of my improvements is to provide a burner for .use in domestic cook-stoves and -ranges that will be sate,y
practical and economical in operation and that will be particularly adapted to the utilization of the heavier grades ot petroleum oil.
With these and other objects in view, to be set forth in the following description oit' my improvements, the invention consists .in the novel construction ol an apparatus that may be installed in the lire-box ot any cookstove or range; which will generate an intense heat in said fire-box so dillused and general that it obviates the common defect among domestic oil burners known to me, of concentration of highly heated gases impinging on particular parts of the stove structure and a consequent damage thereto from unequal expansion; which will volatilize efficiently all the gaseous constituents` even in heavy oils without the agency ot' atmospheric air, thus avoiding under all conditions ol normal use any possibilit-y ot' generating an explosive mixture within the apparatus; whose parts are all readily accessible and detachable to permit ot convenient cleaning andinspection; in which the supply ot' combustible gas is constant, equable and of sullicient volume for all requirements, such as delivering heated gases ot' combustion through the return tlues about the stove oven; and in which all the said combustible gases are consumed and utilized to the fullest extent in the generation ot' heat, as shown by the quantity ol blue llames delivered therefrom and the absen"e otI smoke in the combustion products.
` The invention further consists in the adaptation and combination ot parts, as`
Specification of Letters Patent.

in the accompanying drawings. In said drawings, Figure l is a longitudinal vertical section ol alwparatus embodying my invention; and Fig. is a horizontal view along the broken `line of Fig l with the hood thereot removed and showing the heat retaining ring superposed on the gratmg.
.ln the said drawings, the reference numeral 5 designates a base-pan, preferably rechmgular, as shown, and capable of being located within the lire-box of a range or cooking-stm'e by resting upon the grate thereol, or on any other suitable support. Such pan is desir-ably formed with outwardly llaring sides tl and a bottom 7 having a centrally located boss S provided with a hole t) through which protrudes an upwardly directed oil supply pipe l0 which conducts oil under pressure from a suitable source ot supply, usually an elevated reser- VOIP.
1l is a columnar support, herein shown as having rectangular vertical walls surrounding said supply pipe l0 and forming a compartment 12 therein. The walls of said support serve as a protection to the said supply pipe against undue heating with a consequent carbonization of oil therein. The -air in said compartment is heated to a moderate degree, gradually warming the oil in said supply pipe and atl'ording a reserve of warmed air in close proximity to the points ol combustion. Apertures 13 at the top and bottom ol? said walls atl'ord admission and egress to air within said compartment. Removably seated upon said support, and trmly held thereon by a depending flange lll, is a horizontal rectangular plate l5 having a central boss 1G with a hole 17 therein in axial alinement with the hole t) and a1'- rangcd to receive in close sliding engagement the upper end lll ot' said supply pipe. 'lhe perimeter ol said plate is provided with a double ridge. 1S extending entirely thereabout with a corresponding groove there between. A rectangular hood 19 provided with depending sides il() is arranged to be tilted over said plate and is l'ormed with double grooves 2l with a corresponding ridge therebetween to be seated in the opposing parts t8 ot' the plate. Upon a small -amount ol residue 'from the oil gases genhollow cone 24:.
erated in the vaporizing chamber 22 comprised between the said plate and the hood being deposited at said interfitting contact, a practically gas-tight joint is effected. Said plate is symmetrically arranged longitudinally upon each comprises upon each side of the latter a horizontal plane surface 23 and an inverted Each said concis provided with an open upper end, a vertically arranged nozzle" opening 25 at its lower slightly truncated end, and comprising a superheating chamber 26 therein. The outer walls of said cones may be corrugated to promote the absorption of heat from the combustion chamber 28 and its radiation within the said superheating chamber. The upper perimeter of said superheating chamber is bounded by a wall 29 raised above the surface 23 and of less height than said ridges 18. 30` is an extension of said wall blocking the iow of oil directly to an opening 31 in the wall and causing any oil not vaporized upon the surface 23 to take a circuitous course, as by the passage 32 to obtain access to said superheating chamber.
Directly beneath and about the exterior walls of each of the said superheating chambers and including the space comprised within and between the said base-pan 5 and the hood 19 is what I term the combustion chamber wherein a combustible mixture is formed between the vapors `generated within the chambers 22 and 26 and the oxygen of the air, the vapor being under pressure. To promote the rapid combination of these elements I interposep a grating 33l of cast iron in said combustion chamber raised above the bottom 7 of the pan, as upon legs 34, to afford a space therebeneath. Said grating may be formed with grate-bars 36, or in any suitable manner to provide interstices4 37 communicating with the space Integral with each of said gratings as shown in Fig. 1, or superposed thereon as shown in Fig. 2, is a heat-retaining ring 38 preferably positioned approximately concentric to the nozzle 25.
All of the said parts are or may be made of cast metal and may be readily assembled and removed for inspection or cleaning. The hood 19 is provided with an apertured lug 39 integrally formed thereon by which it may be lifted conveniently. Dirt or residue -from the volatilized oil deposited on the plate may thereupon be readily removed. Said plate may likewise be lifted from the support l1 and the supply pipe, to which latter it is connected, by a slip-joint, as explained.l
It is to be understood that I do not limit myself to the precise arrangement and combination of parts hereinabove set forth and illustrated in the drawings, as it is obvious that various modifications might or could be side of said boss 16 and.
,and openings as may made in details without departing from the spirit of the invention or from the scope of the appended claims.
The operation of the invention may be described as follows: Oil is permitted to flow through the oil-supply pipe l() from the reservoir and may be controlled by a suitable valve (not shown) exteriorly of the stove. Oilemerging from the open end 10 of said pipe overflows over the horizontal surface 23 of the plate upon each side of said pipe. Said plate is highly heated by the combustion of gases exteriorly thereof. Volatilization and expansion of said oil ensues within the chamber 22 and the gas is forced into the superheating chamber 26 where it is further expanded by. heat and emitted through the respective nozzle 25 and impinged against the grate-bars 36.
Free access of atmospheric air, as by an .open draft in the stove to chamber of my apparatus, is obviated as much as practicable as I have clearly shown by experiment that best results are obtained with said devices by closing any direct draft appliance about the stove and causing the air to enter through such occasional cracks be found therein, to break up the total amount of air entering into many currents flowing from diverse directions. By thus reducing and diffusing the amount of oxygen admitted to the combustion chamber and avoiding any direct draft thereof through the ues of the stove, but causing practically all the air entering the tire-box to unite with the hydrocarbon generated and delivered in the manner described, there results a very perfect combustion characterized by an absence from snn 1re and an intensely hot blue iiame. The vapor generated engages with considerable force upon the grating. The vapor thereupon is divided into a great number of broken and eddying currents, some of which penetrate into the space 35 beneath the grating while vothers are deflected laterally against the `ring 38.
o Vair is admitted into the vaporizing chamber, hence there is no danger of explosion. The gas is discharged from the nozzle opening without violence and is consumed in the combustion chamber withouty the unpleasant roaring noise frequently encountered in this class of device. In case of the flooding of said chamber by oil in greater amounts than can be volatilized, it will spread upon the surface 23 and follow the passage 32 tothe opening 31 whereupon it iiows into the superheating chamber 26 and,
if still in excess of the vaporizing capacity of the apparatus, will flow through the nozzle 25 upon thepan-bottom 7. The oil is permitted thus to flow when it is desired to start the operation of the apparatus; the oil received in said pan being ignited to furthe combustion i,
