To. all whom-t mayA concern Be it dknown that-I, LEWIS F. OSTRANDER, a citizenof the' United? States, residing`- at u My invention relatesfgenerally to heating g appliances and-:more:particularlyto. a gas burner,v the principal object ofimy invention beingtof provide a .comparatively Vsimple and inexpensive .gas burner, thef same being;l Constructed so'that the gaseous fuel-and the airtosupport perfect combustion thereof vis preheated; Yto a consider-able degee' prior to I the;

discharge of the gas throughr ther j et lfopenf ings,= and f which construction y is not only economical in point-of fuel cosumptiombut effective gto a maximum degree,I owing to-thei utilization. of all. the thermal energycontainedin the gaseous fuel.

Further objects -ofL my u inventiongfarfe toprovideE ,a comparatively simple gas burner which can: bereadily positioned within the heater when the usual grate isremoved therefromyand .fur-ther .to provide .a gas burner having, an adjustablehood by means of.- :which airis prefheated and delivered tol the iames resultinglfrom. the ,combustion of the gaseous fuel issuingin .jet form from` the burner, and` which actionis effective infprofr ducing perfect combustion-gandthe conservingiand utilization` 0f all: of the-.heat A units produced f such combustion.

As l.illust-rated in the accompanying ,draw-V ings my improved burnerincludes a'hollow With' `Vthe foregoingg and other obj View, my invention consists in certain novel? member 87,: preferably cast, and `formed integral withythe'outer wall thereof atsuitableL distances apart l, are lugs 38 through which are lformed suitableapertures which servey asjetgopenings 89. In the present vinstance',l I ihave show-nA the hollow member 37 the form' of a ring',} but lit will be readily understood that said membercan be square, oblong, or of anydesired` shape and size.

Formed integral :withfthe member 37 4isa ldiametricaljly arranged-hollow member 40 and formed integral with ,the sides thereof are flateral-ly projecting,v flanges 41, thev outer edges -Aofwhich are concentric with the inner iedge ,of ring ,37.`

The gas supply pipe 44'V is connected to;

The lower edgeofothe inner wall or 'leg'offthis Vhoodvvbears directlyupon or is ,positioned immediately adjacent 'to the outer edges of flanges 4l and said innerV wall is `provided onwoppositef sides with notches-48 which accommodate `thevhollow member140-of1theburnerring; The f outer fleg yor' wall `of lthe hoodr is ver? ticlallydispos'edi. with its `lower edge :positioned slightl'yrbelowf theibottom of ring 37 and formed integral with the loweredge ofsaidfouten-'wallAv or leg is an outwardly projecting Vflange 49. u

Formedfthrough'fthe. outer wall of the hood lisfa series tof apertures 50, there being. onefapertureffor each ofthe jet openings 39;v

justing-.screws' 46 and: .by manipulating the I lattera'theheight at which theehood is mainl/Vhere the burners are made in regular sizes, the set screws 46a may be dispensed with, in which instance, the hood rests di-V rectly on top of the lugs 46;

It will be understood that burners con` Ystructed in accordance with my invention can be made in various shapes and sizes so as to be utilized in connection with all forms of stoves, furnaces, fire boXesand the like.

When my improved burner is in use, gaseous fuel is supplied through pipe 44 and passes from nipple 42 into the chamber within hollow member 40, from thence latur erally in both directions to thechamber within burner ring 37 and from which latter, the gaseous fuel discharges in jet form from apertures 39.

Combustion of the jets of gaseous fuel takes place within apertures 50 and immediately outside the outer wall of the hood 47 and the heat resulting from such combustion maintains the hood and the burner ring in a highly heated condition, and as a result, the gaseous fuel entering and passing through the burneris thoroughly pre-heated Vprior to its discharge through the jet openings to the points of combustion.

Further, the jets of gaseous fuel issuing from the apertures y89 and burning imme-v eective results are obtained, and practiu cally all'of the thermal energy of the heat units contained in the gaseous fuel is developed and utilized. p

VRepeated tests which I have made with a burner constructed as hereindescribed have demonstrated the fact that the heat from the burner is increased from V() to 800 degrees F. above the heat developed in burners which are not provided with hoods over the burner rings.

The apertures 50 in the outer wall of the hood are considerably larger than the jet openings 39, and this construction results in a continuous. or circularY area ofA pre-heated air which entirely surrounds and passes outward in the same direction with the ets of flame produced by the combustion of the fuel at the jet openings. In vsome instances, it may be found desirable to utilize slots instead of round jet openings, and

where such construction is carried out, the openings 50 in the outer wall of the hood are correspondingly changed.

A burner of 'my' improved construction is comparatively simple, can be easily'and cheaply manufactured, is adapted for a wideV I claim l. The hereindescribed gas burner com- Y. prising'a hollow burner ring provided with jet openings, a gas supply pipe leading to said hollow member, an annular hood removably positioned overV the hollow ring, the body of which hood Yis of substantially inverted U-shape in cross section, the walls of said hood being spaced apart from said` ring, and there being openings formed 1n.

the outer wall of the hood directly opposite the jet openings. Y

2. The hereindescribed gas burner comprising a hollow member provided with jet openings, means for supplying gaseous-fuel Vto said hollow member, an annular hood positioned over said 4hollow `member, the

body of which hood is of substantially in?V verted U-shape in cross section, Vadjustable means seated in saidV hollow' member Vfor supporting said hood, and there being .openings formed in the outer wall Vof the hood directly opposite the low member.

3. In' a burner of the class described, a hollow memberV provided withA jet openings, a tubular member connecting opposite sides of said hollow member, flanges on said jet openings in the holtubular member, a hood positioned over the'V hollow member, the inner wall of which hood rests upon the tubular member and the flanges thereof, and there being openings formed inthe outer wall of the hood directly opposite the jet openings in the hollow mem er. 'Y Y 4. In` a burner of the class described, a hollow member; provided Vwith jet openings, a tubular member connecting opposite sides of said hollow member, flanges on said tubular member, a hood positioned over the hollow member, the inner wall of which hood rests upon the tubular member andy the flanges thereof, there being openings formed in the outer wall of the hood directly oppo? site thejetropenings inthe hollow member, and adJustable means seated in the hollow member for supporting said hood.

5. The combination with a burner ring. `having a gas inlet and a series of )et open-4 ings,-of an annular hood for said burner ring, the body of which hood is substantially of inverted `U-sliape in cross section with both of its walls eXtending downward to the sides of the burner ring so as to provide an air chamber above and on both sides of the burner ring when the parts are assembled, and there being openings formed in the outer wall of the hood directly opposite the jet openings in the burner ring.

6. The combination with a burner ring having a gas inlet and a series of jet openings, of an annular hood for said burner ring, the body of which hood is substantially of inverted U-shape in cross section with both of its walls extending downward to the sides of the'burner ring so as to provide an air chamber above and on both sides of the burner ring when the parts are assembled, there being openings formed in the outer wall of the hood directly opposite the jet openings in the burner ring, and

means for adjusting the vertical position of the hood with respect to said burner ring.

7. The combination with a hollow member provided with a gas inlet and a series of jet openings formed through its outer'wall, of a hood positioned over said hollow member,

the body of which hood is substantially ofA signature in the presence of two witnesses,
