ALEXANDER JOHN OBRIEN, OF BELOIT, WISCONSIN, ASSIGNOR OF ONE- HALF TO CHARLES A. GAULT, OF BELOIT, WISCONSIN.

OIL-BURNER.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed September 29, 1905. Renewed December 31, 1906. Serial No. 350,182.

To all whmn it may concern:

Be it known that I, ALEXANDER JOHN OBRIEN, a citizen of the United States, rcsiding at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in gasolene burners, and consists in the novel features of construction, combination and arrangement of parts, hereinafter described and claimed.

The object of the invention is to improve and simplify the construction and operation of devices of this character, and thereby render the same more convenient and eflicient in use and less expensive to manufacture.

The above and other objects. which Will appear as the nature of my invention is better understood, are accomplished by means of the construction illustrated in the accompanying drawings, in which,-

Figure 1 is a side elevation of an oil or gasolene burner constructed in accordance with my invention; and Fig. 2 is a vertical sectional view through the same.

Referring to the drawings by numeral, 1 denotes a gas generator, which is in the form of a cylindrical casting formed with a centrally-disposed, tapered opening 2, through which the tapered end of a burnertube 3 is ada ted to project. The small open end 4 of the urner-tube projects slightly above the top of the generator 1, and its large open lower end 5 is bent at right angles, as shown. In said tube 3, slightly below the bottom of the generator 1, is formed an annular series of apertures or openings 6, through which jets of flame project, when the burner is in operation, for the purpose of heating the gasolene or other oil in the generator 1. Gasolene or other oil is supplied to said generator through a supply-pipe 7, which leads from an oil tank or reservoir 8 to the lower portion of the generator, as shown. In the suppl ypipe 7 is provided a suitable valve 9, by means of which the supply of gasolene or oil to the burner may be readily controlled. The gas generated in the generator 1 passes out of the upper portion of the latter through an outlet tube 10, which extends downwardly and has upon its lower end a needle valve 11, the outlet of which is disposed centrally in the open lower end 5 of the bmner-tube 3. Upon the top of the tank 8, beneath the needle valve 11 and .the end 5 of the burner-tube is provided a drip-cup or pan 13.

The construction, use and advantages of the invention will be readily seen. In starting the burner, the generator 1 is heated sufficiently to cause the gasolene therein to gasify and discharge through the needle valve 1.1 into the lower end of the burner-tube. Air is injected into said tube by a jet of gas, and the llames shoot out of the open top 4 ofthe burner-tube, as well as through the apertures 6 in the-latter. Any form of flame-spreading device a may as shown in Fig. 1 be applied to the top i of the tube 3, according to the use for which the burner is to be adapted. W'hen used in a stove, a cap or spreader plate is preferably spaced above the top of the tube 3, so as to throw the flames laterally around the top of the generator. By applying a long pipe or tube upon the end 4 of the burner-tube 3 as indicated at b in Fig. 2, the device may be used for thawing out frozen water pipes and. the like.

The burner is of simple, durable and incxpensive construction, and is convenient in use and perfectly noiseless in operation.

Various changes in the form, proportion and the minor details of construction within the scope of the appended claim may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is,-

In a liquid hydro-carbon burner, the combination of a tank or reservoir, a valve-controlled supply-pipe projecting vertically therefrom, a cylindrical gas generator upon the upper end of said supply-pipe and in communication therewith, said generator being provided with a tapered centrally-disposed opcning, a burner-tube having its tapered upper end projecting through said opening and extending slightly above the top of said generator, the lower open end of said burner-tube being formed with an annular series of apertures, and being bent at right 1zitlngles, a gas discharge tube leading nesses. frolnt eu er ortion of saidgeneretor,and T a needle 351v; upon said discharge tube ALEMNDER JOHN OBRIEY 5 adapted to discharge gas into the lower open I WVitnesses:
