UNITED STATES PATENT GFFICE.

HENRY BOUNIJS CARY, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO FREDERICK W. BRAUN, OF SAME PLACE.

GASOLENE-BURNER.

SIECIFIGATION forming part of Letters Patent No. 665,670, dated January 8,1901.

Application filed January 4:, 1900. S ri l No. 3'79. N m l To all whom it may concern! Be it known that I, HENRY BOUNDS CARY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Gasolene-Burners, of which the following is a specification.

My invention relates more particularly to an appliance for generating the vapors in starting the burner into operation. Said generatoris applicable to various forms of burner, but is especially adapted for use with a form of burner known as an open Bunsenburner and for which I have filed an application for Letters Patent of the Uni ted States, Serial No. 715,237, filed May 1, 1899, and in which a generating-chamber is provided at the end of the burner opposite the jet-piece and a pipe leads from the generating-chamber to supply the jet-piece.

An object of my invention is to provide convenient and thoroughly-effective means for quickly and readily generating the vapor for starting the burner into operation.

Another object of my invention is to provide for readily igniting the vapors in the generator from the flame from the burner, and vice versa. I

The accompanying drawings illustrate my invention.

Figure I is a perspective view of my improved gasolene-burner. Fig. II is a side elevation in longitudinal section on line II II, Fig. III. Fig. III is a front elevation of the burner. Fig. IV is a cross-section on line IV IV, Fig. II. Fig. V is a fragmental plan view to illustrate the front end of the generating-shell.

(1. indicates the generating-chamber.

b indicates the body of the burner proper for which this invention is more especially designed to be used.

0 indicates the pipe leading from the generating-chamber for supplying gasolene or vapor to the main burner jet-piece d.

e indicates an auxiliary jet-piece connected with the jet-pipe c and arranged to direct a jet along beneath said pipe.

f indicates a shell arranged beneath the pipe to inclose the jet and provided with air-inlets g g and extending toward the generatingchamber and provided near such chamber with an outlet h for the flame and with an imperforate mixer-section h between the airinlets and the outlet h. Preferably the shell is in the form of a trough, and the openings are above the bottom of the trough, and the trough extends underneath the generating chamber.

'6 indicates the gasolene-supply pipe, which opens into the generating-chamber. j indicates the Valve for controlling the same.

In practical use to start the burner into operation gasolene will be turned on through the supply-pipe 'i and will flow into the generating-chamber a and thence into the jetpipe 0 and to the auxiliary jet-piece e, which will then be opened to allow the gasolene to flow out beneath thejet-pipe Q. will be caughtin the troughfand Willthere be ignited by the operator. The flame rising from the trough will heat the j et-pipe and the gasolene therein and will thereby produce the inflammable vapor,which then flows through the auxiliary jet-piecee and through the duct inside the shell or trough f beneath the j et-pipe 0. At first while the pressure is low and the hydrocarbon vapor is practically undiluted with air it will issue at and can be ignited at the air-inlets g g and will burn all along the jet-pipe above the openings of the shell, thus to quickly heat the jet-pipe; but as the tension of the vapor increases the velocity of the jet will carry it through the shell and air will be intrained at the openings 9 g and will be carried into the imperforate mixer section h of the shell, where it will become mixed with the hydrocarbon vapor. The mixture of air and hydrocarbon vapor formed in the mixer-section h of the shell will be of a proper richness of hydrocarbon to ignite as it issues at h and will there produce a flame to heat the generating-chamber a, as Well as the end of the jet-pipe c. When the vapor has been brought to a sufficiently high tension, the main jet-piece at will be opened and the vapor-jet will be blown through the body of the burner, and when it issues at the farther end of the burner it will be ignited by the flame from the auxiliary jet, and the burner will then come into perfect operation. The auxiliary jet may then be cut off; but so long This gasolenecan as the main jet is ignited the auxiliary jet may be ignited at any time by simply opening the auxiliary jet-valve k. The trough formed by the shellfbeing open at the front end, as indicated, and extending beneath the generating-chamber conducts the inflammable vapors to the front of the generatingchamber, thus to beignited by the flame from the burner. The generator-jet Will thus be ignited Whenever it is turned on While the burner is in operation. In case the tension of the vapor should become too low at any time the auxiliary jet will be turned on and its flame used to produce a required heat for the generator.

m indicates a clamp by which the shell f is detachably attached to the jet-pipe c.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In a gasolene-burner, the combination of a generating-chamber; a main jet-piece; a pipe communicating between the generating-chamber and the main jet-piece; an auxiliary jet-piece connected with said pipe and arranged to direct an auxiliary jet along beneath said pipe; and a shell arranged beneath the pipe to inclose the auxiliary jet and provided with air-inlets and extending toward the generating-chamber and provided near such chamber with an outlet for the flame and with an imperforate mixer-section between the outlet and the air-inlets.

inlet and the flame-outlet.

3. In a gasolene-burner, the combination with a main jet-piece and a pipe for supplying a jet of vapor to the main jet-piece; of an auxiliary jet-piece connected with said pipe and arranged to direct a jet of gasolene or vapor along beneath the pipe; a shell arranged beneath the pipe to inclose the et and provided at intervals with inlets to admit air, and with an outlet at the end opposite the auxiliary jet-piece and an imperforate mixer-section between the air-inlets and the outlet.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, California, this 28th day of December, 1890.
