BURNER FOR LIQUID HYDROCARBONS AND VAPORS THEREOF.

SPECIFICATION forming part of Letters Patent No. 397,595, dated February 12, 1889.

Application filed September 3, 1886. Serial No. 212,608%. (No model.)

To all 1071,0721, it may concern.-

Be it known that I, WARREN T. KELLOGG, of Lansingburg, in the county of Rensselaer and State of New York, have invented new and useful Improvements in Burners for Liquid Hydrocarbons and the "apors Thereof, of which the following is a specification.

My invention relates to improvements in apparatus for burning liquid hydrocarbons and other oils in furnaces where intense heat, without regard to illumination, is required; and the object of my invention is to aiford means for the proper vaporization of the oils and for obtaining the necessary admixture of atmospheric air with said vapor to produce a more perfect combustion of the oils, and consequently the generation of a greater heat than is obtained by a direct combustion of said oils. This object I attain by means of the apparatus illustrated in the accompanying drawings, which are herein referred to,'and form part of this specification, and in which Figure 1 is a front elevation of my burner; Fig. 2, a plan view of the same; Fig. 3, a vertical section at the line :0 x of Fig. 2; and Fig. at a reduced side elevation of my burner connected with its oil-supplying reservoir.

As represented in the drawings, A is the outer casing or shell of my burner, which is preferably made in the form of a circular pan and is provided with a series of air-tubes, a, whose openings extend through the bottom plate of said casing. Near the bottom of said casingits outer wall is perforated with a series of openings, a,through which air is admitted to support the combustion of the oil contained in said casing, and in the bottom of the latter is placed a layer of asbestus, sand, or other material suitable for holding in suspension a quantity of oil in condition for burning.

B a vaporizing-chamber or retort, which is fixed within the casing A in such manner that a clear space will be left between the bot toms and sides of said retort and the casing A. Said retort is provided with a central tube, 1), which should be integral with the bottom plate of the retort, and by which an annular chamber is formed in said retort. An annular cover, 1), is fitted to close over the annular chamber of said retort, and said cover and the face. of the oil-holding material at the bottom of the casing A to permit a proper combustion of the oil to be maintained beneath the bottom plat-e of the retort B.

D is an oil-reservoir, which may be fixed in any position that is conveniently near the burner, and at a suflieient height above the latter to insure the passage of the oil from said reservoir to the burner by the force of gravity. Thevertical part of the oil-supply pipe C, which connects said reservoir with the burner, is provided with a supply-regulating valve, 0, which is located between said reservoir and a small nozzle or drip, 0 through which the oil can be regulated to feed in as minute quantities as occasion may require. Said nozzle is contained in a gaging-cage, 0 having glass sides, through which the nozzle can be readily seen, thereby affording means for visibly determining as to the sufficiency of the supply of oil that is being fed to the burner.

The several parts being constructed and arranged substantially above described, the operation of my apparatus will be as follows: The oil from the reservoir D is fed through the supply-pipe C and passes through the nipples 0 into the interior of the vaporizing-clhamber B. From the latter a portion of the oil drips through the loose joints around the air'tubes ainto the lower part of the casin g A, wherein it will be absorljied by the layer of asbestus, where it will be ignited, and by the heat gen erated by this primary combustion the oil contained in the vaporizing-chamber B becomes vaporized and escapes in a gaseous form from said chamber through the loose joints formed by the cover 1) around the airtubes a, and as fast as this vapor or gas is emitted through said joints it becomes eommingled with the currents of air which pass up through air-tubes a, and this mixture, becoming ignited from the flame of the oil burning in'the casing A, burns with an intensity of heat that is fully equal to that of the wellknown Bunsen gas-burner. This burner is especially designed for use in the furnaces'of steam-generators, caloric engines, and other apparatus where an intense heat is required; and it is obvious that its construction is not limited to the precise number of air-tubes and points of gas ignition shown in the drawings.

I claim as my invention- 1. The combination of a primary combustionchamber provided with a series of vertical air-tubes which have a free opening through themfrom top to bottom, a vaporizing-chamber fixed within said combustion-chamber so as to leave a clear space between the sides and bottoms of the two chambers, the air-tubes of said combustion-chamber passing loosely through the top and bottom plates of said va porizing-chainb'er, and an oil-pipe arranged to deliver its supply of oil primarily into the vaporizing-chamber, as and for the purpose herein specified.

2. The combination, with a casing, A, provided with standing air-tubes a, and having a bottom layer of asbestus or other absorbent material, of a vaporizing-chamber, B, contained in said casing, and having the air tub'es a passing therethrough, so as to leave leaky joints around said tubes at the top and bottom of said chamber, and an oil-supply pipe, 0, adapted to primarily feed the supply of oil into the vaporizing-chamber B, all being arranged to operate as herein specified.
