SPECIFICATION forming partof Letters Patent No, 747,434, dated December 22, 1903.

Application filed November 25, 1902. Serial No. 132,809. (No model.)

burner of that class in which oil-gas is gen erated and mixed with a certain amount or percentage of air and adapted to burn a low grade of refined oil, ordinarily known asa distillate oiland of a low gravity, or any ordinary petroleum-oil generating an oilgas which will burn with an intense heat and a clear flame. The burner is easily attached to any type of stove, range, furnace, boiler, or wherever Wood or coal is'used for heating and cooking. In disposing the improved device in a stove, range, or other heating means it is placed in an upright position in the firebox or combustion-chamber after removing the grate and replacing the latter with a draftplate having a central opening therein over which the improved burner is held.

The improved burner meets all the requirements for liberating hydrogen gas from on by bringing the latter as an entirety into direct contact with the hot surface of a hermetically-sealed retort or vaporizing-dome. The flame when the burner is in operation is circular in form and located at the lower end of the burner, and the function of the draftplate is to supply the oxygen and permit it to be absorbed by the hydrogen of the oil and produce an intense heating-flame. The air and gas can be proportionately supplied to each other at will, and the supply of oil .is under the control of a needle-valve to raise and lower the flame by the regulation of the flow of oil, and thereby maintain a' steady uniform heat at any temperature desired.

In the drawings, Figure 1 is a transverse vertical section of the burner on an enlarged scale. Fig. 2 is a top plan view'of the lower portion of the burner with the vaporizing dome or retortremoved. v.

ing through the center thereof.

, The numeral 1 designatesa draft-plate constructed of. suitable metal and of such dimensions as to accurately fit within a fire-box or combustion chamber of a stove, range, or other analogous device and having an open- The complete vaporizingburner is held at a suitable elevation above the plate 1 by means of an oil-feeding pipe 3, which passes down centrally through the plate and outwardly from I the stove, furnace, range, or other device at any suitable point and connects with an oilsupply tank at a convenient location. At a suitable point within the oil-supply pipe, ex-

teriorly of the range, stove, or other heating device, is a needle-valve of usual construction, which is operated to control theflow of oil through the said supply-pipe. The supply-pipe 3 extends upwardly a suitable distance and connects with an interiorly-screwthreaded collar 4;, depending from the lower extremityof a gas-supply chamber 5, forming a part of a vaporizing chamber 6 of shell-like form. The bottom of the chamber 5 is formed with a series of gas-outlet openings 7, and rising from the collar 4 and extending centrally through the chambers5 and 6 is an oil-feeding pipe 8, having a distributer or spreader 9 secured on the upper end" thereof and comprising a series of radial arms 10 with grooves or gutters 11 in the upper sides thereof, communicating at their inner terminals with a central recess 12. The

arms 10 have their upper surfaces inclined downwardly toward their outer ends, and the upper, end of the oil-feeding pipe 8 is completely opened to the recess 12. The feedingpipe Sis wrapped with an asbestos wick or strip 13 to serve as a means for starting the packing-seat for the reception of an asbestos ring 15, and at diametrically opposite points ears 16 project outwardly from the upper edge of said chamber and. are apertured to receive connecting devices. Disposed over the upper open end of the chamber 6 is a retort or vaporizing-dome 17 of inverted conical form and formed with a lower depending rib 18, extending entirely therearound, of the same width as and adapted to be firmly pressed against the packing-ring to establish a tight joint between the mixing-chamber and the retort or dome. The retort or dome also has diametrically disposed apertured ears 19, and t-herethrongh and through the ears l6 connecting-bolts 20 are inserted and hold the vaporizing-chamber and the re tort or dome in immovable joined relation.

I The arms 10 of the distributer or spreader are of less diametrical extent than the interior of the vaporizing-chamber and the retort or dome, and said distributer or spreader is held at such elevation as to be in operative proximity to the inner surface of the retort or dome. To render the mixing-chamber 6 more eifective in its operation, it is circumferentially corrugated, as at 21, to form a series of troughs or gutters to receive the oil and retard its downward flow tosuch an extent as to insure a rapid preliminary vaporization, particularly in starting the burner.

In starting the burner the needle-valve in the supply-pipe is opened to permit a small.

quantity of oil to flow outwardly over the arms 10 of the distributer or spreader, it being understood that the oil-supply tank will be located at such an elevation that the oil in seeking a level corresponding to that in the tank will flow over the arms of the distributer or spreader in the manner stated. The needle-valve is then closed, and the oil from the arms passes down to the under side of the distributer or spreader and is absorbed or flows over the asbestos surrounding the oil-feeding pipe 13. A torch or other igniting medium is then applied close to the bottom of the chamber 5 to ignite the oil on the asbestos 13 through the openings 7 and that which remains in the gutters 11 of the arms 10. The combustion of this initial supply of oil thoroughly heats the entire burner and places it in a condition for rapid vaporization, and after a certain length of time the needlevalve is again opened and the oil permitted to flow into theheated burner, where it is vaporized, and the gas passes down to the chamber 5 and out through the openings 7, Where it absorbs the oxygen fed through the plate, and the mixture becomes ignited and forms a circular white flame about the lower end of the burner. The combustion of the gas at the lower end of the burner establishes a suction which draws the air through the plate 1, and the liberated oxygen mixes with the hydrogen of the oil and sets up a flame of intense heating qualities. The heating capacity of the burner is regulated, as before indicated, by the amount of oil permitted to run into the burner, and as the latter is practically closed thorough vaporization and combustion of the oil will ensue and an intense heat will be regulated.

It will be understood that the proportions and dimensions of the several parts of the burner may be varied at will to accommodate difierent applications, and it is proposed to use metal in the construction of the several members which are affected by the intense heat of such degree of hardness as to render the same virtually refractory, and thereby prolong the practical use of the improved device.

Having thus described the invention, what is claimed as new is- 1. In a heating device of the class set forth, a draft-plate with a single opening through the center thereof, a. closed vaporizing-burner supported above the draft-plate and having a connection with an oil-supply and a gaschamber with bottom outlets, the connection with the oil-supply passing upwardly through the chamber and said outlets forming the sole means of escape of the gas from the heating device, an oil -distributer held within the burner at an elevation above the gas-chamber and to which the oil directly feeds, said distributer being provided with radial arms havin g grooves extending longitudinally thereof, and an asbestos Wrapping around said means for supporting the oil-distributer, a space being formed between the outer surface of the asbestos wrapping and the adjacent wall of the burner of the heating device whereby the vaporized oil or gas is permitted to flow downwardly toward and out through the bottom outlets of the gas-chamber.

2. A heating device of the class set forth, comprising a hollow closed vaporizing-burner with lower gas-outlet openings, the latter forming the sole communicating means to the exterior of the burner, an oil-feeding pipe extending upwardly into the interior of the burner and having an asbestos wrapping thereon, a distributer held on the upper extremity of the feeding-pipe and having radial arms over which the oil flows to the wrapping on the pipe holding said distributer, the said arms being regularly spaced apart and having a combined diameter less than the interior diameter of the portion of the burner where they are positioned, and means for supplying oil to the burner.
