Be it known that I, BENJAMIN F. LAWToN,

a citizen of the United States, residing at Riv-V erdale, Morris county, NewJersey, have in- Vented certain new and useful Improvements in Ilydrocarbon-Burners, of which the following is a specification.

My invention relates to means for burning Huid hydrocarbons, either gaseous or liquid,

for raising steam and for other kindred purposes; and the leading objects of the invention are to provide means for producing a mixture o f air and hydrocarbon gas or vapor which shall have the maximum combustible qualities and leave no liquid or solid residues,

and also to provide heated air for admixture with the hydrocarbon.

Other features of the invention relate to the Figure l is a longitudinal vertical axial section of the burning apparatus and boiler.

Fig. 2 is a side elevation of a part of the same,

illustrating the igniting feature; and Fig. 3 is a transverse Vertical section on line :1:3 x8 in Fig. 1. Fig. 4 is an axial sectional view of the mixer and burner proper on a larger scale,

than the principal views.

Fig. 5 is asectional view of a more simple form of the inlet-nozzle for the hydrocarbon.l

A represents a steam-boiler of a known kind, having three tiers of tubes or tlues a', The two lower tiers of tubes open at the front into a chamber a, and the upper tier opens in to a breeching a", which leads the gases to an uptake or chimney c4.

At the rear end of the boiler is what I de-l nominate the burner apparatus. Within a casing B of this apparatus are three chambers b', b2, and b3. The upper chamber b is closed except to the two uppermost tiers of boiler-fines c and a2. The middle chamber b2 is the combining-chamber for the combustible gases and the lower chamber b3 is the air-chamber. Air enters an air-pipe c through a register-controlled inlet cxand passes to the air-chamber b3 through the pipe c, 4which latter passes through the chambers b and b2.

The air rises 'from the chamber b3 into the` combining or mixing chamber b2 through perforatious in a partition bx, which separates the'chambers b2 and b3.

I will now explain the construction of the device, (shown best in Fig. 4,) and which I call the ,mixer and burner, as it serves as a mixer forA the air and' hydrocarbon and may serve, also, as a burner, although it does not do so, in the proper sense, as arranged in Fig. l. This mixer and burner D comprises an air-chamber d, to which-air is admitted at vinlets dx, controlled by a rotativelymounted register-plate d. This air-chamber is separated from a mixing or combining chamber d2 by aperforated diaphragm cl3. The casing of the chamberd2 has in it numerous perforations d4 to allow the combustible mixture to escape. The hydrocarbon is admitted to the chamber d2 through a pipe or tube d5, which extendsV up through the diaphram d3 and bears on its upper outlet end an outlet-chaml ber d6, with a vperforated crown. .'lo regulate the influx of gas through the pipe d5, I setin the socket dia slitted tube ds, through which the gas must iow, and provide this slitted tube with a cut-off screw (i9, by which the area of the slits through which the gas must flow can be varied in length by merely driving down orl drawing back the screw. This is merely a device fo rregulating the quantity of gas to be admitted, performing somewhat the functions of a register. This burner and mixer Dis situated in the combining-chamber b2' and is supplied through a pipe d10. The admission of air at the inlets dX-is easily regulated by turning the apertured registerplate d about the lpipe d5.

So far as described the operation is as follows: Gas, for example, is admitted to the combining-chamber dbeing broken up by passing through the perforated crown of the chamber d6. Air, or a mixture ofair and gas,

enters the chamber d2 through the diaphragmA IOO plained, into the chamber b3, and thence up through the perforated partition bx into the chamber b2. The intimately-combined inflammable mixture of gas and air now passes from the combining-chamber b2, through perforated diaphragms b4, into outlet-nozzles b5, extending from the wall of the combiningchamber b2, across an ignitingv chamber h6, into the respective rear ends of the ilues a3 of the boiler A. The igniting-ehamber has a door bl, in Fig. 2, at which to ignite the gases tiowing through the nozzles b5, the latter having apertures b8 to afford access to the stream of combined gases. The ignited gases flow forward through the lues a3 to the chamber a, thence back through the tlues a2 to the chamber b', and thence forward again through the flues a to the breeching ctx and out at the chimney. It will be noted that the hot gases in the chamber b surround the pipe c, which passes through and may have a bend or coil in the chamber b', and the air flowing through such pipe is thus highly heated.

As the device shown in Fig. 4 is a mixer in itself, it may be used as a burner similar to the burner of a lamp, the ignition being effected where the vmixed or combined gases emerge from the perforations (Z4.

As the device included in the casing B is in itself al mixing and combining device, irrespective of the particular construction of the device seen in Fig. 4, I may employ in lieu of the device D a simple inlet nozzle or device DX. (Seen in Fig. 5.) rIhis device of Fig. 5 is in effect the device of Fig. 4E with the air-chamber CZ, the mixing-chamber d2, and the perforated diaphragm d3 omitted.

I do not limit myself strictly to all of the details of construction herein set forth, as these may be varied to some extent without departing materially from my invention.

Having thus described my invention, I claim-- l. The combination with a steam-generator having lines, of an apparatus connected theret. with for mixing hydrocarbon vapor or gas with air in proper proportions for use, said apparatus comprising an airchamber b3, means for introducing heated air to said chamber,acombining chamber baperforated diaphragm or partition between the chambers b2 and b3, a pipe to lead the hydrocarbon to the chamber b2, a mixer or nozzle on the delivery end of said pipe, means for leading the mixed air and hydrocarbon to the flues of the boiler, and an igniting chamber whereat f the gases are ignited at the point where they enter said lines, substantially as set forth.

2. The combination with a steam-generator having three tiers of hues a', a2 and a3, the 1 chamber ct, connecting the front ends of the tiers of flues a2 and a3, the breeching ax, to 1 receive the gases from the upper tier of flues a', and the stack d, of the chamber b', connecting the tlues a and a2 at their rear ends, 65

The combination with a flue-boiler or steam-generator, of an igniting chamber D, at the rear end of the flues of said generator, said chamber provided with a door, means for mixing air and hydrocarbon gas or vapor, a chamber to contain said mixed gas and air adjacent to the igniting chamber, a screened outlet for said gases where the latter pass to the generator tlues, and nozzles b5, extending from said outlets into the tlues across the igniting chamber, said nozzles having apertures bs, to permit of the ignition of the gases, substantially as set forth.

4. In an apparatus for mixing heated air with hydrocarbon gas or vapor, a chamber b', adapted to receive heated gases, a hot airchamber b3, an air-pipe c, extending through the chamber b and adapted to deliver air to the chamber b3 in regulated quantity, a combining or mixing chamber b2, a perforated partition bx between the air-chamber and said combining chamber, and a pipe adapted to lead hydrocarbon gas or vapor to said combining chamber in regulated quantities, said combining chamber having a screened outlet for the mixed gases, substantially as set forth.

5. In a hydrocarbon burner, the combination with the supply-pipe d10, the tube d5, connected therewith, means for regulating the supply'of gas passing from the pipe d10 to the tube d5, the air-chamber d, about the tube d5, means for regulating the admission of air to said chamber d, the mixing chamber cl2, having outlet perforations in its top or crown, the perforated diaphragm d3, between the airchamber and the mixing chamber, and the chamber or perforated nozzle d6, on the end of the tube d5, within the mixing chamber, substantially as set forth.
