JAMES A. KENWORTHY, F LDS ANGELEE, CALIFGRNIA.

GAS BURNER.

Application filed January 18, 1922. Serial Ho. 530,013.

To all whom it may concern:

Be it known that I, JAMES A. KENWORTHY,

. a citizen of the United States, residing at ent entitled Gas Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Gas Burners, of which the following is a specification.

My invention relates to an improved gas generator and burner, and is especially directed to an improvement on my generator and burner constuction as illustrated and described in my nited States Letters Patenerators and burners, 1,417,745. issued ay 10th, 1922. In the construction above referred to I have provided a casing having a gas generating coil mounted therein, and a centrally disposed air supply tube within the casing, the gas discharge outlet of the generator being disposed in tangential relation to the burner casing.

While the above described construction has proved highly eiiicient and economical in operation, I have discovered that by employing a substantially cylindrical casing and admitting the fuel supply centrally thereto, and at the some time forcing the air supply to the interior of theburner casing tangentially, I am able to effect simplicity of nanilfaeture of the generator burner without sacrificing eiiiciency and economy in operation.

The object of this invention is to provide a generator burner construction consisting of a body portion having fuel and air inlets leading thereto, a compressed air inlet disposed tangentially with respect to said body portion so as to cause a whirling action to the} burning fuel during the operation of the burner, and at the same time to effect a thorough atomization and complete combustion of the liquid fuel.

Other objects and advantages will be apparent from the following description, and as illustrated in the accompanying drawing, in which:

Fig. 1 is a central vertical section through my burner.

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1, looking in the direction indicated by the arrows thereon.

Fig. 3 is a transverse section through my burner casing embodying a modified form.

Referring more specifically to the drawin 5 designates a casing having a substantizilly flat bottom 6, and an annular wall 7 extending upwardly therefrom. The diameter of the upper end or the casing is preferably less than the diameter directly above the bottom wall 6, thus forming a restricted flame exit opening, the bulging configuration of the casing wall preventing any liquid fuel being carried or creeping upwardly and outwardly from the casing by the air pressure before complete vaporization.

The bottom wall 6 is provided with a centrally disposed .fiuid inlet opening 8 into which is screwed or otherwise secured a fluid supply pipe 9 that lea s from a source of fuel supply tank (not shown).

Adjacent the bottom wall 6 is formed an air inlet opening 10 in the form of a pipe preferably formed integral with the annular wall or" the burner casing, and having its outer end internally threaded for the reception of an air pipe line that leads to a source of air supply (not shown); Air inlet opening is arranged at a tangent to the annular wall '2 of the burner in order to cause a whirling motion to the air on its entrance to the interior of the burner casing.

The inner end of air inlet opening 10 is of smaller diameter than the outer end, and is preferably elongated transversely with respect to the burner casing so that the air may be forced within the casing in a comparatively thin horizontal sheet, this method of iadmittingair tending to a more complete vaporization of the liquid fuel.

In Fig. 3 of the drawings l have shown a modified form of burner casing in which the casing 5 is provided with a plurality of air inlets, preferably located at diametritrated in Figs. 1 and 2 of the drawing, both of said air inlets discharging air in the same general direction.

In the operation of my improved burner liquid fuel is admitted to the burner through the fuel pipe line 9, the oil flowing in an even volume over the bottom floor 6 in the burner casing, :from whence it is carried in a whirling motion by the air which is forced thereto through the air inlet opening 10. As the air irilet opening 10 is arranged tangentially with respect to the wall 5 of the burner casing and above the bottom fioor of the casing it will at once he noted that as the air passes over the liquid fuel in the bottom of the burner it will become richly surcharged with the liquid fuel to form a highly combustible vapor, also the whirling motion of the air within the casing will tend to produce a partial vacuum in the center of casing and thus further assist inthe complete carburization of the liquid fuel.

The form illustrated in Fig. 3 which is provided with two air inlets, is for the purpose of uniformly cooling the entire Wall of the burner casing, the Wall opposite the air inlet, as shown in Fig. 1, becoming much more highly heated than that portion of the Wall adjacent the air inlet open ing. By forming the peripheral Wall of the burner casing in a pot form and with a restricted opening, all tendency of the oil to creep upwardly and outwardly without becoming vaporized is prevented.

By means of the construction herein described, it will at once be obvious that I do away with all generator pipes that are liable to become clogged with carbon, and that there is no need of a firing pan to start the burner in operation as in usual constructions. The flame issuing from the burner will have a whirling motion and will distribute the heat therefrom in a uniform and even manner throughout the fire box in which the burner may be located.

By means of valves which may be secured to-the fuel inlet and air inlet pipe lines the ratio of the oil and air can be readily regulated.

What I claim is:

l. A gas generator and burner, comprising a substantially cylindrical casing open at the top and closed at the bottom, said casing having a liquid fuel supply opening leading thereto in the bottom well thereof, and provided With an air supply opening in said casing wall arranged to diszieeeeca charge a current of air to the interior of said casing tangentially with respect to the cylindrical wall. the burner 2. A gas generator and burner, compris; ing a casing of annular form open at the top and closed oi: the DOt'iOlliyfillG opening at the top portion being of less diameter than the lower portion of said casing, said casing being provided with a. liquid fuel inlet in the bottom Wall, and, having a compressed air inlet leading thereto arranged tangential to its annular wall, whereby to cause a whirling motion to the air on an operation of the burner.

3. A gas generator and burner construc tion, comprising an annular Walled chasin ber open at the top and having liquid fuel inlet leadin thereto said walled chasm oer being further provided with an air in let arranged above the fuel inlet end disposed tan entially to said well where n the i c .1 7 3/ air current admitted therethrough will be given a whirling motion on an operation of the burner.

4. A gas generator and burner construction, comprising a walled chamber havin a liquid fuel entrance leading thereto, sai chamber having a lame outlet leading therefrom, said Walled chamber heinag inrtlier provided with .an air inlet errenged tangentially to said walled chamber and lead ing to the interior thereof, said sir inlet being located above the fuel of and in said Walled chamber, whereby compressed air will be given a whirling motion to effect a vaporization of the liquid fuel;

in Witness have hereunto subscribed my name this 15th day of December, 1921.
