GASOLENE-BURNER FOR INCANDESCENT LIGHTING.

Specification of Letters Patent.

Patented Get. 24, T916.

Application filed June 26, 1914. Serial No. 847,424.

To all whom it may concern:

Be it known that I, WILLIAM E. Vonz, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Grasolene- Burner for Incandescent Lighting, of which the following is a specification.

Objects of the present invention are first to avoid the troubles due to carbonization and to produce a steady incandescent light from gasolene derived from oils containing a large percentage of compound of the aromatic series, such as asphalt base oils or Texas oils; second, to provide a vaporizing burner for VVelsbach mantles, or other incandescents, in which there is a good distribution of heat, and third, to avoid the use of packing in the burner tube and to insure a full supply of liquid at the point of vaporization, while at the same time preventing carbonization in the feed tube and providing against back pressure efiects in the feed tube.

The invention will be claimed at the end hereof, but will be first described in connection with the accompanying drawings, in which Figure 1, is a side View, generally illustrative of one application of a burner of the invention. Fig. 2, is a side view of a burner embodying features of the invention, principally in section. Fig. 3, is a side view taken at right angles to the plane of Fig. 2, and principally in section. Fig. 4, is a top or plan view with parts removed. Fig. 5 is a fragmentary view, drawn to an en larged scale, and Fig. 6, is a horizontal section of the vaporizing chamber.

In the drawings 1 is a mixing tube, sometimes also called a Bunsen tube, and it is provided with a jet device 2 arranged to discharge into its lower end.

3, is an interrupted annular vaporizing chamber surrounding the mixing tube and it is interrupted as at 4.

5, is a burner head arranged on the mixing tube and provided with openings shown as arranged in groups 6 and 7 and adapted to afford downward sub-jets directed toward the chamber 3 for heating it.

8, is a jet connection from one side of the interruption 4 of the chamber 3 downward to the jet device 20 As shown in the drawings the described parts, along with the braces or stays 9 and 10, make up a structure to which there is applied a wind shield 11 and a feed tube 12.

The feed tube is unobstructed and is pro the feed tube is screwed for the purpose of cleaning it. The groups of openings 6 and 7 are arranged on opposite sides of the interruption 4 and this arrangement tends to promote a good distribution of heat and, as shown, there are more openings or holes in the group 7 than in the group 6, so that by this arrangement more heat is applied at the outlet part of the chamber 3 than at the inlet part.

The level of liquid or gasolene is free to rise in the tube 12. One way of accomplish ing this is to connect the tube 12 as by a valved pipe 15 with an elevated tank or reservoir 16. There is a series of gauze diaphragms 17 arranged in the tube 12 and spaced apart in the general positions indicated in the drawing.

The mode of operation of the burner may be described as follows: When the burner is cold and is to be lighted the level of liquid in the tube 12 may rise pretty well up to the upper end of the tube. Heat is then applied to the burner as from a torch, with the result that vaporization is started and the burner lighted. Thereupon the torch is removed. Sub-jets playing downward through the openings of the groups 6 and 7 heat the vaporizing chambers with the result that gasolene is vaporized and passed by way of the connection 8 through the jet device 2 into the tube 1, where it mixes with air and a part of the mixture is burned on top of the burner head to heat the mantle A, while another and very small part of the mixture supplies the sub-jets. The vaporization of the liquid or gasolene in the chamber 3 gives rise to some back pressure in the tube 12 and the gauze.

may not cause surging of the light, while at c f Gqp es 1 th sra may b6 --0bt 1 r this back pressure may cause the level of liquid in the tube 12 to descend and it will descend until it reaches one of the gauzes 17. The effect of the gauze 17 is to increase the surface tension of the liquid to such an extent that the back pressure is resisted by the surface tension of'the liquid in respect to In this way the back pressure the same time heat is not conducted through the tube 12 to an extent or degree suflicient to produce carbonization .and furthermore there is always sample feed of liquid to the point of vaporization. It may be said in [connection with the gauze that it subdivides the meniscus of the liquid as it would exist in the absence of thegauze, producing :a multiplicity of smaller menisci,

thereby increasing thesurface tension so as to oppose back pressure.

What I .claimis:

1. A .gasolene burner tor incandescent lighting comprising the combination of a mixing tube having a jet device, an interrupted annular vaporizing chamber surrounding the tube, a burner head arranged on the tube and provided underneath with openings affording downward sub-jets for the chamber, a jet connection from one side of the interruption of the chamber downward to the jet device, an upright gravity feed tube communicating with the chamber to the other .side of its interruption and in which :the liquid level is :free to rise, and a series of spaced gauze .diaphra'gms in the upright portion of said tube which by increasing fluid tension holds the liquid level :at one or the other-of said gauzes,:substantially .as described.

2'. A gasolene burner for incandescent lighting comprising the combination of a mixing tube having a jet .device, an interrupted annular vaporizing chamber surrounding the tube, a burner "head arranged on the tube and provided underneath with openings aiiording down-ward sub-jets for the chamber, balls or like bodies in the chamber, a jet connection from one side of the interruption of the chamber downward to the jet device, an upright gravity feed tube communicating with the chamber to the other side of its interruption and in which the liquid level is free to rise, and a series of spaced gauze diaphragms in said upright tube which increase fluid tension and hold the liquid level at one or the other of the gauzes, substantially as described.

3. A gasolene burner for incandescent lighting comprising the combination of a mixing tube having a jet device, an interrupted annular vaporizing chamber surrounding the .tube, a burner head arranged on the tube and provided underneath with openings affording downward sub-jets for the chamber, a jet connection from one side of the interruption of the chamber downward .to the jet device, an upright gravity feed tube having a lateral jet discharge nozzle communicating with the chamber to the other side of its interruption and in which tube the liquid level is free to rise, and a series of spaced gauze diaphragms in said upright tube which increase fluid tension and tend to hold the liquid level at one or the other of the gauzes, substantially as described.

4:. In a gasolene burner for incandescent lighting the combination of a vaporizing chamber, an upright gravity feed tube communicating with the chamber and in which the liquid level is free to rise to the chamher, and ,a series-of spacedgauze diaphragms in said tube which increase fluid tension and hold the liquid level at one or the other of the gauzes, substantially as described.

In testimony whereof I have hereunto signed my name.
