Be it knownthatl, HARRY-M; Hannioma citizen of the: United States, residing in'the city and. county, ofv Philadelphia, -State of Pennsylvania, haveiuventeda new and useful ImprovementinBurners, which improve; 1 'ment is fully set 'fo-rtlrinfthe following specif fication and accompanying drawings. My invention relates to burners g iand it 10 consists in the employment of an auxiliary series of gas-superheating chambers which are located in such relation above and in proximity to the generator properemployed that the gas contained,in said chambers becomes intensely heated and aplurality of flames are produced which are opposed to each other in such'a manner that the inten sity of the light is greatly increased thereby without adding tothe consumption of vapor. It further consists in avnovel manner of assembling the burners of the'auxiliary gasholding chamber, which latter are formed within a plurality of branches which have mantle-supporting devices thereon, whereby a 5 said auxiliary gas-chambers are subjected to a highly-increased degree of heat and the flow of the gas from the burner-tube by reason of the construction of said chambers is somewhat retarded, so that a maximum 'qu antity of heatnnits are abstracted from each contiguous branch and serve to further heat the gas contained in said chambers prior to ignition.

It further consists of novel details of gconstruction, all as will be hereinafter fully set forth, and particularly pointed out in the claims. r

Figure 1 represents aplan view of a burner employing my invention. 0 a side elevation thereof, partly in section. Fig. 3 represents a side elevation of a portion of Fig. 2.

Similar letters of reference indicate corre sponding parts in the figures.

.Referring to the drawings, A designates a hydrocarbon-inlet which is controlled by a suitable valve B, said hydrocarbon passing upwardly through the pipe C to the generator D and thence out through the pipe E as ber,although it will,of course be evident Fig. 2 represents a gas.o1' vapor to the gas-chamber F, cone 5:: tainedwithin thecasing G, theoutlet"from thelatt er being'through the injector tip H. J designates a burner-tubefwhichiis made preferably flaring atjit's'lower portion Kand is 'inthe present instancesupported upon the v casing G, the upper'port'ion of saidtube Jbe- 'ing' provided with openings L, around which. is placed the gauze M, whereby heat can-flow throughsaid openings and. thereby be im parted-to thegenerator D, so that the latter is heated .toafhigh degree being in practice almost a cherry-red f -N designates a gauze supported upon the upper portion of' the burner-tube J, the latter having supported thereupon the auxiliary gas-superheating chambers P, which are contained within the casing Q, the same being shown in the present instance as being com- I posed of branches, which are three in mum-- that this number may be increased or diminished, according to requirements, said casing having a neck Q, by which it is secured to the tap of the burner-tube. ,The casing Q-is provided with a top; portion R, which serves to deflect andto a certain extent retard or check the egress of the hot gases, the same leaving. said chambers P through the upwardly-turned outlets S, which latter have screens or gauze T thereon. i

U designates bosses or projections secured to suitable portions of the casing Q, in which the rods Vare supported, said rods sustaining the mantles W. .The generator D is prefer-' ably provided with a supporting-post X of suitable conductin g material, whereby a high degree of heat is conducted to the gas-chamber F, so as vto assist in thoroughly volatilizing the hydrocarbon employed.

N designates a tuft of very fine wire or similar material interposed between the top portion of the burner-tube J and the under side of the gauze N, said tuft serving as a strainer and to thoroughly break up the gas before the same reaches the chambers P.

The operation is as follows: The hydrocarbon, which is preferably gasolene, is forced up the tube 0 to the generator D, down the tube E into the chamber F, and thence into the burner-tube, at the same time drawing in the requisite supply of oxygen by reason of the flaring mouth K. When the hydrocarbon reaches the top of the burner-tube, it is momentarily retarded and escapes out the openings L, at which point it is ignited, and the heat here generated is imparted to the generator D, which becomes highly heated, and consequently the hydrocarbon which flows through the generator at this stage becomes converted into a gas, some of the heat being conducted from said generator to the lower gas-chamber F by means of the conductive port X. The hydrocarbon is in the meanwhile passing through the straining material N and the gauze'N, after which it flows into the auxiliar heating-chambers B, and after impinging against the top R thereof it escapes through the gauzes T, at which points v it is ignited and burns with a steady white,

flame of great brilliancy.

The casing Q of the auxiliary chambers is heated to a high degree by radiation from the generator D and also by the auxiliary flame adjacent the latter, whereby the contents of said casing are highly superheated prior to ignition, and the heat from each of the mantles being imparted to the burnerimmediately therebelow it will be apparent that the heat units are effectively utilized for the purpose of superheatin g the hydrocarbon prior to final ignition.

I have found by experiment that a cluster of two, three, or more lights arranged so that their reservoir or casing Q, is subjected to the intense heat of the generatorD substantially in the manner described will, while consuming only slightly more hydrocarbon than a single light or burner, give proportionately twice or three times as much light, according to the number of burners used, the advantage of this construction thus being apparent.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combinationof aburner-tube, a generator adjacent the upper portionof the lat- 2. The combination of a burnertube having ports in the upper portion thereof, a generator located adjacent to said ports and having a pipe leading therefrom to a gas-chamber below said tube, asupporting-post of conductive material "com mon to said gas-chamber and to said generator, a casing containing auxiliary gas-su-perheating chambers supported above said tube and having gauze and straining material located in the path of the gas to said casing, burners leading from said casing, bosses or projections upon said burners, rods mounted in said bosses and mantles supported upon said rods.

3. The combination ofa burner-tube, a generator adjacent the upper portion of the latter' and heated by the fiamesissuing through ports in said tube, auxiliary gas-superheating chambers supported above said generator, the outer portions of said chambers being heated by, radiation from said generator and the inner portions thereof being heated by the flames impinging on said generator, a gaschamber below saidburner-tube and in communication with said generator and an injector-tip located in the outlet from said gaschamber and projecting beyond the casing of the latter.
