VAPOR-GASOLENE BURNER.

srEcrFrcA'rIoN forming part of Letters atent'No. 727,087, dated May 5, 1903.

Application filed January 2, 1902. Renewed March 24,1903. Serial No. 149,396. (No model.)

To all whom it may concern:

Be it known that I, HARRY M. BURNELL, a citizen of theUnited States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Vapor-Gasolene Burners; and Ido 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in gasolene-burners more especially intended for use on automobiles or horseless carriages, my object being to provide a device of this class which shall be simple in construction,Y

economical in cost, reliable, durable,and thoroughly practicable in use; and to these ends the invention consists of the features, arrangements,and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a top or plan View of my improved burner, shown in det-ail. Fig. 2 is a section taken on the line y y, Fig. 1. Fig. 3 is a section taken on the line z z, Fig. 1. Fig. 4 is a section taken through the combustion-chamber and the outer drum,

showing the cut-olif slide for regulating the draft from below. Fig. 5 is a section taken on the line o: w, Fig. 1. Fig. 6 is a section taken on the line P P, Fig. 2.

The same reference characters indicate th same parts in all the views.

Let the numeral 5 designate the body of the burner, which consists of a circular mixing-tube 5, a .straight mixing-tube 5C, and jet-tubes 5d. The straight mixing-tube extends diametrically across the circular space inclosed by the circular tube, its intake extremity or nozzle 5g being located between the terminals 5h of the circular tube and communicating with two air-ducts 5i, which enter the nozzle from opposite sides, being formedin theintegral casting which, as shown in the drawings, comprises the circular tube,

parts may, however, if desired, be cast in sep- `arate-pieces and fastened together in any suitable manner.

The tube 5c at its extremity remote from the intake or nozzle communicates with the circular tube, thechannel being separated by a divider 6, consisting of a plug screwed into the core-hole formed in the casing opposite the extremity of the tube 5c, the inner extremity of the plug being beveled to form a separate partition. By removing this divider free access is obtained to the straight tube for cleaning purposes. This divider also facilitates the flow of gas from the straight tube to the circular tube in both directions. (See Fig. 6.) The jetftubes v5d are mounted above and in contact with the straight tube 5 and, as shown in the drawings, extend at right angles thereto. The extremities of these jet-tubes open into the circular tube, whose outer walls are also provided with core-openings 4 in line with the jettube openings. The core-openings are closed when the device is in use by a circular band 7, extending around the circular tube on the outside and fastened in a manner to be readily detachable,whereby access is gained to the jet-tubes for cleaning purposes. The upper edges of the jet-tubes project above the plane of the mixing-tube. These edges are beveled and formed with transverse saw cuts or slots, forming a great many openings for the escape of gas, a jet of iiame being at each opening when the device is in use. There are narrow longitudinal spaces 8 be tween the fines, allowing freedom of draft from below.

The burner is mounted in a casing 9, supported below the boiler 10, andv its bottom is provided with awire-gauze diaphragm 12 to exclude the dirt, while permitting freedom of circulation of air for draft purposes.

Surrounding and attached to the combustion-chamber is a drum 13, Whose bottom plate 14 is provided with draft-openings. The passage of air through these openings is regulated and controlled by a cut-o slide 15, mounted on the drum and having openings arranged to register withv the openings in the bottom of the drum when the plate is properly adjusted. The draft from below may IOC be entirely cut olf by properly adjusting the slide 15.

My improved construction possesses a number of advantageous features. It embodies a considerable length of mixing tube arranged in convenient compass. The air-ducts 5 with which tubes 16 are connected communicate with the outer air and allow a steady and uniform introduction of air for mixing purposes unadected by Winds, gusts, or currents of air. The air is also hot When it joins the gasolene at the nozzle, having passed through a sufficient length of duct for this purpose. The upper edges of the jettubes 5 being raised above the body of the burner, prevent the undue heating of the latter.

Having thus described my invention, what I claim'is- 1. Agasolene-burner comprising a circular mixing-tube and a straight tube extending diam etrically across the space in closed by the circular tube, the straight tube having an intake at one extremity and communicating at its opposite extremity with the circular tube at a central point, and a series of jet-tubes filling the circle surrounded by the circular tube and communicating With the latter at both extremities, the jet-tubes being located above the plane of the straight tube and having gas-outlets at the top, substantially as described.

2. A gasoleue-burn er comprising a circular mixing-tube,a straight tube diametrically arranged with reference to the circular tube, communicating with the latter at one extremity and having an intake at its opposite extremity, the body of the burner being provided with air-ducts communicating` with the intake extremity of the straight tube, and a series of jet-tubes communicating at their opposite extremities with the circular tube and having jet-openings at the top, substantially as described.

3. A gasolene-burner havinga circular mixing-tube,astraight mixing-tubediametrically arranged with reference to the circular tube and communicating with the latter at one extremity, the circular tube having an opening in its outer Wallin line with the straight mixing-tube, a plug inserted in said opening and protruding into the straight tube, forming a separated partition for directing the gas into the circular tube in opposite directions, and jet-tubes extending at right angles to the straight tube and communicating at both extremities with the circular tube, substantially as described.

4. The combination of a mixing-tube arranged in the form of a circle inclosing a space of suitable area, a straight tube diametrically arranged and communicating at one extremity with the circular tube, the opposite extre mity being the intake for the volatile fluid, a series of cross jet-tubes communicating at both extremities with the circular tube, and having jet-openings in their upper edges which are beveled, the said jet-tubes being separated by narrow' longitudinal spaces permitting draft from below, a Wire-gauze diaphragm stretched across the bottom of the burner, a combustion-chamber leading upwardly from the burner,and a drum surrounding the burner, extending below the same and having a perforated bottom, and a cutoff slide mounted on said drum, substantially as described and for the purpose set forth.

5. A gasolene-burner comprising a circular mixing-tube, a series of jet-tubes communieating at their opposite extremities Withthe circular tube and having jet-openings formed in their upper edges, the circular tube having core-openings in its outer Wall in line with the jet-tubes, and suitable detachable means for closing said openings, substantially as described.

6. A gasolene-burner comprising a circular mixing-tube, a series of parallel jet-tubes lling the space inclosed by the circular tube and communicating at their opposite extremities with the circular tube and having suitable jet-openings, the circular tube having core-openings in its outer wall in line With the jet-tube openings, and a band passed around the circular tube for closing said coreopenings, substantially as described and for the purpose set forth.

In testimony whereof l affix my signature in presence of two Witnesses.
