More specifically, 8 indicates fthe burner ilY in section as'seen on fr body, whichv isv formed 'at its ends with-disc-V- like portions 9 and V10,` arranged toextend horizontally, and inthe direction Jofthe" ,e

length of the 'burner body and ,with the end 85.

portions' disposed l0n substantially thesame plane.- *The end portions 9 and 10 of the burner body afford a" support and mounting for a pair ofburner headsll and 1'21e'spectively, 'and for whichpurpose each ofV the vportions) and 10 is ormedwith an annular marginal fiange or lip 13, and an upwardly extending annular ange`v 14,"'the outer periphery of which Harige is spaced 'in-y wardl ya short distance from the outer mar; gin o the lip 13'. Each burner head comon lthe lip 13 with its inner periphery Vspaced '95 ,prises an annular'side wall Y15, which seats l a short distance from the outer yperiphery of the flange 14. Thewall 1 5 extends'above the upper c edge V of -the flange 14 andv connects with a circulartop plate 16 in the case of the 'case of lburner head V12, which top plate projects over the space boundedby the wall 15 and is spaced from the upper surface'of the end portion `of the burnervr body.- Thef burner head thus formed, is heldin place by meansV of screws 17, which f' are passed through openings in the top plates 16 and 16 and whichxare screwed into'engagemex'it'with`I the end,V portions'of the' burner-.bodyr'as par# ticularly shownin 'Figure 3*.' The annular side wall 15 of each burner head is formed with a plurality of superposed rows of perforations 18. Any suitable number of such rows of perforations may be provided as occasion may require; one or more of the rows of perforations 18 being located between the upper face of the lip 13 and the upper edge 'of the flange 14 and constitute air inlet openings, and one or more rows of the perforations extend between the upper edge of the flange 14 and the top plates 16 and 16 constituting burner orifices.

The burner body 8 is hollow and is formed intermediate the ends thereof with an enlarged chamber 19 constituting a vapor reservoir which chamber con'uuunicates at its opposite ends with reduced passages 2O and 21; the passage 2O being upturned and opening directly into the space within the burner head 11 and the passage 21 opening into a horizontally extending cylindrical chamber 22 formed in continuation of the passage 21, from which chamber leads a side port 23 opening into the space within the burner head 12. The outer end of the chamber 22 is closed by a cap 24 through which extends a longitudinally slidable stem 25 having a plunger valve 26 Amounted thereon within th-e chamber 22 and which valve is adapted to be positioned to regulate the flow of fuel to the burner head 12 by sliding the valve longitudinally of the chamber 22 to vary the tent of opening of the port 23 and whereby 'the burner head-12 may be placed out of operation by positioning the plunger valve 26 between the port 23 and the outer end of the passage 21 so as to close the latter. The burner body is provided with a vapor and air intake indicated generally at 27 and which embodies an upwardly extending tubular projection of approximately U- shaped form including a. vertically extending air intake portion 28 leading upwardly from the top face of the burner body and connecting with a horizontally and downwardly extending portion 29 opening to the chamber 19; the interior of the portion 29 constituting a. mixing throat. An air inlet opening 30 is provided in the wall of the portion 28 contiguous to the top face of the burner body and formed in the upper part of the side wall of the portion 28 is an opening 31 into which projects a nozzle 32 on the end of a generating tube 33; the nozzle being arranged to project vapors horizontally into the mixing throat from whence the vapors intel-mixed with air drawn into the mixing throat through the air inlet opening 30 will be delivered to the reservoir chamber 19 and thence 'flow to the burner heads. The generating tube 33 extends over the top plate 16 of the'burner head 11 and is spaced a short distance therefrom. The top plate 16 is formed with a pair of rows of elongated burner orifies 34 and 35 which are formed as particularly shown in Figures 5 and 6 and which burner orifices are adapted to direct flames against the generating tube 33.

The top plate 16 of the burner head 9 is formed with a central depression 36 constituting a generating pan to which leads a fuel supply pipe 37 opening. horizontally above the pan 36. As a. means for holding the generating tube 33 and the pipe 37 in proper relation to the burner head 11 a plate 38 is mounted on the top plate 16 of the burner and is held in place thereon by. the screws 17; this plate being formed with a central opening 39 over the pan 36 and having side straps 4() formed thereon extending over the generating tube at each side of the opening 39 and being form-ed at o-ne end of the opening with an upstanding strap 41 through which the discharge end of the pipe 37, extends and rising from the margin of the opening 39 opposite the open end of the pipe 37 is a fia-nge 42 which serves as a Haine guard. I y Y In the operation of the invention, after initial heating of the generating tube 33, a hydrocarbon fuel is delivered to the latter from any suit-able source of supply and is vaporized in the usualV manner. The vapors thus formed are delivered to the interior ofthe burner body intermixed with air as before stated; the mixture filling the reservoir 19 and being delivered from the latter to the burner head 11 from whence the mixture is discharged through the burner orifices 18, 34 and 35 and arehere ignited to set the burner head 1l in operation. If desired, a portion of the mixture is delivered to the burner head 10 on opening the port 23, and on passing through the burner orifices 18 in the burner head 10 are ignited to set the latter burner head in operation.

An important feature ofthe invention resides in providing a reserve supply of the mixture of hydrocarbon vaporV and air in the chamber 19 so that in event a burner head is Y exposed to a draft tending to momentarily,

induce a flow of vapors from the burner head faster than ordinarily would be suppli-ed by the generator, the reserve of vapors in the chamber 19 will be drawn upon to maintain the flame at the burner head.

While the manner of carrying the invention into effect is specilically set forth herein, I do not limit myself to the exact construction, arrangements and embodiments shown and described, as the invention is subjected to various changes, modifications and applications, and accordingly, the invention as herein defined is to be understood in a comprehensive sens'e. i
