This invention relates jto an improvement l in burnerslof the typ? Vfog-Tiri111g"tliewsu-bf je@ matter f .my ,coren'qlirs ppli'atol, led January -1,192G,Serial $81,779. j One Lof the 'principal objects ofthe invention isl to provide a` burner which thoroughly commingles ,the gasiror rother fuel lused and thelair to produce a highly Combustible meterle .adapted @albe buriedv m to Agenerate a maximumamount of heat with economy in the@Hampton@free and little or no .deposit of carbon.

u Another objecty yof lthe inven-f l,tion is to I,provide a burner having reversible i; jets so constructed and organized to producev either alaterally" directed or Aan up-y wardly directed sheet bf flame thereby making the burner readily adaptable for various types of boilers and to meet varying 2o conditions,

A further object is to provide a burner which is of simple and durable construction, reliable and efficient in operation, and easy and comparatively inexpensive to manufacture.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawing forming a part of this specication, and in which Figure 1 is a perspective view showing a burner constructed in accordance with the present invention and illustrating the jets thereof in a. position to provide a horizontal sheet of flame,

Figure. 2 is a sectional view illustrating the construction of the burner and the mounting of the burner pipes, and

Figure 3 'is a detail perspective View of one of the burner pipes.

Referring to the drawings, the numeral 1 designates generall a furnace or boiler in the rebox of whic the burner constitutting the present invention is placed. The burner is supported at the upper end of a casing or fuel supply pipe 2. The gas pipe 2 delivers the gas or fuel in through the bottom 3 with a as chamber designated generally at 4, and 2having a body portion 5 of frusto-conical form. The gas chamber also has a top wall 6 which is provided with an annular extension 7 from the outer edge of which a depending apron 8 of frustoconical 'form extends, the apron 8 being parallel t the'body portion 5 of the gas `'chamber andY terminating in the planeof theffbottom of the chamber. As illustrated Figure '2, the outer wall of the body por# tion of the cham-ber'l and the apron- 8 ACoact to define an air chamber 9. 'A

' 'The body portion 5 -of the gas chamber is providedwith a circularfseries of openings f IO'thrugh which the gasissues in thefform Of 'jets' lThe apron 8 has openings 11y lalined with the .openings 10, and as illustrated in Figure 2, both the openings 10 'andll are preferably'inclined upwardly.

In the openingsv 11 the'apron 8 burner pipes designated generally yat y12 are mounted." Thewallsof they openings 11 are tapered as 4shown-at 11a, VFigure'2, and the inner ends of the vburner pipes are similarly tapered as indicated at 12a. This provides for the side joint between the burner pipes and the apron, and in order to enhance the mechanical connection between the burner' pipes and the openings, and prevent turning movement of the burner pipes in their openings, each burner pipe has oppositely extending lugs 13 engageable with grooves 14 in the apron 8 between the openings 11. Each burner pipe 12 has a body portion 15 which is straight and a discharge end 16 which extends from the body portion at an angle of substantially 45C. This angularly extending discharge end portion 16 Vhas its outer end closed and has jet openings 17 at each side of its outer end. When the burner pipes are positioned as shown in Figures 1 and 2, the flame which they generate is horizontally disposed in the furnace. However, by taking the burner pipes` off of the apron and turning them'or reversing them, the discharge end portion 16 may be disposed to extend vertically whereby the burner pipes create a vertically extending sheet of flame in the furnace or boiler.

If desirable, the air supplied to the space 9 may be supplied through the ordinary dampers or through the ash pit, or if a forced draft is used, through an air supply duct 20, which is connected up with the lower end of the apron 8.

I claim 2- 1. A burner including a gas chamber having a body portion provided with discharge openings, said gas chamber having an extension at its upper end and an linclined pendent apron carried by the extension and overlying the body portion of the gas chamber and having openings alined with the discharge openings of the gas chamber, `and burner pipes mounted in the openings of the apron, said apron defining with the body portion an air space whereby the jets of gas issuing from the openings ofthe body portion entrain air and carry it into the burner pipes whereby a combustible mixture is produced, said burner pipes having'their inner ends tapered, the walls of the openings of the apron being correspondingly tapered,

, said burner pipes having oppositely disposed lugs, said apron having grooves coacting .with the lugs.

openings of the gas chamber, and burnerpipes mounted in the openings of the apron, said apron defining with the body portion an air space whereby the jets of gas issuing from the openings of the body portion entrain air and carry it into the burner pipes whereby a combustible mixture is produced, said burner pipes having theirl outer ends angularly disposed so as to extend horizontally in one position and vertically in another position.

3. A burner including a gas chamber having a' body portion provided with discharge openings, said gas chamber having an extension at its upper end `and an inclined pendent apron carried by the extension and overlying the lbody portion of the gas' chamberand having openings alined with the dischargek openings of the gas chamber, and burner pipes mounted in the openings of thev apron,

"said, apron defining with the body portion an air space whereby thejets of gas issuing V`from the openings of the body'portion env train air and carry it into vthe burner pipes whereby a' combustible mixture is produced, said burner pipes having their outer ends provided with discharge openings and also being angularly dispose'dso as to extend in' different directions and different positionsV ofthe burner pipes.r 'y
