Specification of Letters Patent. Patented il 1 .16.,- 1921.
Application filed August 25, 1919. Serial No. 319,742.
To all to 7mm it may concern I I Be it known that I J OHN R. BA'rns, a citizen of. the United nois, have invented certain new anduseful Improvements in Hydrocarbon-Gas Burners, of which the following is a specification. The object of this invention is to provide agas burning-heater of the type whi ch-burns oil vapor generated in a retort heated by the burner itself, which has a number of novel features rendering it more convenient in use and more efficient in operation than burners of this type heretofore used or suggested. I I I More particularly the present inventlon comprises a neat and substantial gas burner mounted upon a novel and improved stand, which has incorporated therewith a priming device of great convenience and efiiciency, which employs a self-cleaning valve of new design, which is provided with a heat retaining hood for deflecting the heat from the burner plate to the generator for the purpose of keeping the generator hot even when the burner is not turned on full, and which has other novel and important details of construction rendering it a more convenient and efficient article than other burners of its type now in use.
One embodiment of the invention will be disclosed in the following description when taken in connection with the accompanyin drawings in which:
Figure 1 is a plan view of the burner, part of the cap being broken away to show the interior construction; I I I 1 I Fig. 2 is a side elevation of the same, part of the priming panbeing broken away;
Fig. 3-is a side elevation from the left, Figs.1and2;. 1 I

Fig. '6 is a vertical section through the gas valve and adjacent parts;
Fig. 7 isa perspective view of the novel I ing, controlled by a suitable valve, directed supporting stand; I I I Fig. 8 is a perspective viewof the prlm ng pan with its heat retaining shield, and
Fig. 9 is a section along the line 9-9 oi Fi 6. I
The base portion 10 of the burner 1s supported upon the pedestal 11, the foot 12 of gtates, residing at Chi-' .cago, in the county of Cook, State of Illiwhich is slidably held to the stand 13 by lugs 14;. I The base 10 is preferably a casting, cylindrical in shape and having a mixing chamber 1( 3 extending from one wallapproximately a d ametrical distance of three-fourths of the dlstance across the base. I have shown this mixing chamber to be substantially square in cross-section and with side walls 17 and 18 extending between the bottom 19 and the top 20 of the base but the exact shape of the mixing chamber may be varied as desired. An opening 21 is made in the end. wall of the chamber to serve as'an exit for the gases introduced through the mouth 22 of the same.
Surrounding the mouth 22 of this chamber and preferably integral with the baselO is a back fire curtain 23 which prevents the flame from the burner from contacting with and igniting the unburned gases entering the mixing chamber. I
Holes 24 are provided'in the top 20 of the base outside of the mixing chamber and the gases passing throughthe opening-"'21, circulate around the interior of the base and pass upwardly through the openings 24 into the space between the base 10 and a cap 25 havmg a concave bottom, which rests on lugs 26 projecting upwardly from the top of the base. The gases pass outwardly from between the base and thecap in an annular.
stream and pass upwardly between the outer wall of the cap and the cylindrical burner plate 27 which is provided with a large number of small holes 28 through which the gas passes. Upon passing outwardly through the holes 28 the gas is ignited and burns freely in a well known manner. The cap 25 is provided with a hood 29 which extends approximately one-fourth of the distance around its circumference at its upper edge and this hood serves to deflect downwardly the heat of the, burner below it upon the top of thegas generator30. This gas generator 30 comprises substantially a pipe or retort adapted to have threaded connection at 31 with an oil supply pipe and at its other end provided with an openinto the mixing chamber 16. The generator is secured to the base of the burner by two generating gases. I As clearly shown in Fig.
2 the main portion of the generator is hori- Zontally disposed and is arranged along the top of the burner plate 27 immediately under the hood 29. This arrangement is important and has been found particularly advantageous inasmuch as it permits the generator to be properly heated and to operate efficiently even when the gas has been partially turned off and flames are issuing from the burner only near its top, there being practically no combustion at the lower openings in the burner. In oil-gas burners now in use the generator has been disposed practically universally around the lower portion of the burner plate and when the gas is turned low and the flames are present at the upper part of the burner plate only the generator is no longer efliciently heated and soon ceases to generate the necessary quantity of gas, with the result that the flame soon goes entirely out. By arranging the generator at the upper portion of the burner plate and by providing the hood 29 for deflecting downwardly the heat on to the top of the generator I have totally obviated these difficulties.
The flow of gas from the generator into the mixing chamber is controlled, as before stated, by a needle valve 33 having a stem 34: and a handle 35 secured to its outer end. This valve is of usual construction with the exception that it is provided with a selfcleaning feature for removing the carbon deposit which constantly forms at the valves of all burners of this character. In Fig. 9 a large crosssection of that portion of the valve immediately behind the needle point is indicated by the numeral 36. This portion of the valve has the form of a flat plate provided on its opposite edges with knife edges 37 which are designed to scrape the walls of the gas passage 38 each time the valve stem is rotated. The scrapings of carbon from the inner wall 38 fall to the lower endof the generator 30 and may be removed at intervals by unscrewing the plug 30 at its lower end. In the normal operation of the valve the action of these knife edges 37 maintain thepassage from the generator to the' gas orifice controlled by the needle valve free from carbon and it is never necessary to take out the valve for cleaning purposes.
Another feature of my invention is the provision of a novel priming pan indicated at 39 in the drawings. This priming pan is hinged to the base lugs 40 and 41 of the pan and base respectively, being provided with alined openings to receive a pivot bolt 42. The pan is arc-shaped and when folded in to the base extends substantially under the generator, throughout the length of the latter. As the generator takes a downward bend to the gas valve the priming pan is made with two levels, the upper level for heating the higher part of the generator and the lower level for heating the lower part of the generator. A heat retaining shield 43 preferably integral with the priming pan extends from its upper edge approximately up to the top of the generator and this shield directs the heat from the burning alcohol or other combustible fluid in the pan against the bottom of the generator and greatly increases the efficiency of the priming pan. The shield 43 curves outwardly at its free end and the portion 44: is adapted to fit over and rest upon the valve nut 45 to support the outer or free end of the priming pan and to take the strain from the bolt 42.
In the operation of the device both levels of the. priming pan are filled with alcohol or similar fluid which is ignited and the priming pan placed in position under the generator. The heat from the burning alcohol soon vaporizes the oil in the generator. The valve may then be opened and the gas issues in a jet into the mixing chamber drawing in through the mouth of the back fire curtain 23 a considerable quantity of air which is thoroughly mixed with the gas in passing upwardly to the burner plate 27. As soon as the gas is ignited at plate 27 the generator is heated from this source and the priming pan is no longer necessary, the heat from the burner plate being sufiicient for the generation of gas in the generator even when the burner is turned low because of the arrangement of the generator along the upper edge of the burner plate, and the pro design and construction of the invention and I do not limit myself to the exact form shown and described.
What is claimed is: p

In an oil-gas burner, a base portion, a cylindrical burner plate mounted thereon, a curved generator disposed to be heated by the combustion at the burner plate to generate gas, and a curved priming pan hinged to the base portion and adapted to be swung away from said generator to befilled and ignited and to be moved under the genen ator when ignited to heat the same.
