SPECIFICATION forming part of Letters Patent No. 709,387, dated September 16, 1902. Application led July 3, 1901. Serial No. 67,006. (No model.)

To a/ZZ 1071/0711/ it muy' concern,.- Be it known that I, ERNEST BETZ, a citizen of the United States, and a resident of Washin gton, inthe District of Columbia, have made a certain new and useful Inventionin Hydrocarbon-Burners; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the artto which it appertains to make and use 1o the invention, reference being had to the ac.

companying drawings and to letters of reference marked thereon, which form a part of this specification.

Figure l is a side elevation of my burner.

r 5 Fig. 2 is a perspective view of the burner with cap-plate G removed. Fig. `3 is a plan View of the burner. Fig. e is a partial vertical lon-` gitudinal section of the same. i The invention relates to hyd rocarbon-burnzo ers, `and has for its object theprovision of a simple and practical device of thisoharacter especially suited for burning kerosene-oil and arranged tojheat the oil to effectually convert it into vapor, also providing for the admixn ture of heated air with such vapor for com-` plete combustion thereof toobtain a flame of T maximum caloriic value."

A further object of the invention is to provide for such complete' combustion as will avoid the exhalation of odor from the burner.

y consists in the novel construction and combinations of parts, as hereinafter set forth.

`Referring to the accompanying` drawings,

the letter B designates the burner, and C the oil-feed pipe, supplied from a suitable oil-res` chamber E, through which the extension of` the oil-feed pipe from the reservoir passes. This hot-air chamber is provided with an airinlet in its bottom portion and with an airexit e in its top, such air-exit being laterally 5o arranged and provided with a deflector plate or ange e' above said opening to guide the `With these objects inview the invention The base-casting, 'usually (of rectangular or At the side of orA adjacent to the oily` rising heated air toward the mixing-tube located adjacent thereto. At the opposite side of the base a similar hot-air chamber having similar air inlet and exit passages is usually provided, as shown.

The mixing-tubes F are supported by small arms attached to the top of the base near the air-openingsin the top ofthe hot-air chamber.

From the oil receptacle or retort, being at- 6o tached thereto by means of a threaded opening in itstop, extends the coil-pipe c, which is disposed horizontally.above the base and, extending downward, is connected to the burner-tube c', which extends under the mix- 65 ing-tube and is provided with a burner-tip projecting upward into the same.

`Above the base is a deflector-cap G, which is designed to be secured to the base by means of attachment-lugs g therein being bolted to 7o similar lugs of said base. This `cap G has small openings g2 g2 in its top Wall and separated by the bridge-'bars g3, located directly above `the mixing-tubes to obstruct the direct draft immediately over the same. The cap is designed to be provided with a downwardly and outwardly inclined flange, which extends n nearlyito the top of the base, leaving an opening between its margin and said base, sai openingbeingcontinuous,exceptat thepoin s 8o of attachment of the cap to the base. This flanged cap practically incloses the coil-pipe and the mixing-tubes and forms a dame-chamber of powerful heating capacity, whereby not only these parts are raised to high temi perature, but also the base including its closed oil-chamber and hot-air chambers are heated, the ,former sufficiently to vaporize the oil therein and the latter to heat the draftair to the mixing-tubes. The margin of the 9o depending iiange of the cap is usually made et' wave-like contour in order to subdivide the burning mixture of gas and air as it passes outward thereunder, in this wise giving it a spreading character, whereby its flames rising exteriorly around the cap are designed to envelop it, and thereby produce a mass of fire of very powerful character.

In operation, the valve of the oil-feed pipe being opened, the oil is allowed to pass into roo the oil-chamber E, wherein it rises through the coil-pipe and passes out of the burnertips, falling upon the base-plate, where it is lighted. The burning oil lsoon heats up the burner-tips and coil, vaporizng the oil therein, and the vapor mixed with air becoming ignited heats up the parts further until the entire burner is raised to a high temperatu rev, vaporizing the oil in the oil-chamber, as well as in the coil-pipe. A continuous flame of powerful character is designed to be produced by the burner.

The heating capacity of the burnerl is such that it burns up all the vaporized oil, which escapes, and theodor which may exhale when the supply is cut off is imperceptible.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- A l. In a hydrocarbon-burner, the combination with the base, its oil-receptacle and hotair chamber belowits top, the inclosing deflector-cap supported from said base, and having a depending flange extending downward nearly to said top, the' mixing-tube and coilpipe within said cap., the burner extension of said coil-pipe under said mixing-tube and above the top of said base-plate, and the oilfeed pipe extendingwithin thehot-air chamber to said oil-receptacle., substantially as specified.

2. In a hydrocarbon-burner, the oil-receptacle and the adjacent hot-air chamber forming a base, the pipe from said receptacle, and its burner-tip, on said base, the mixing-tube above said base, said chamber having air inlet and exit openings in its bottom and iop walls respectively, thev deflector-plate above 1 said exit-opening, and the oil-feed pipe passing through said hot-air chamber, substantially as specified.

. 3. A hydrocarbon-burner, comprising the t base, its' oil-chamber and'adjacenthot-air chamber, the mixing-tube supported therefrom, the coil-pipe from said oil-chamber extending to said mixing-tube, and provided base of box `form divided by a partition to form an oil-receptacle and a hot-air chamber, the mixing-tube supported from said base, the cap supported upon said base, and having a top, and a depending flange inclosing said tube and coil, and the oil-feed coil-pipe extending from the oil-chamber upward between the base and cap, and downward under the mixing-tube, substantially as specilied.

5. A hydrocarbon-burner, comprising the base of box form divided by a partitionto form an oil-receptacle and a hot-air chamber,

Vthe mixing-tube supported from said base,

the oil-feed coil-pipe provided with a burnertip, the cap supported upon said base, and having a depending flange inclosing said eoil and tube, said flange being of such vertical extent as to leave only a narrow opening between its`margin and the base, and said hotair chamber having. air inlet and exit openings in its bottom and top walls respectively, substantially as specified.

In testimony whereof I aftix my signature in presence of two witnesses.
