BURNER My invention relates to improvements in burners for gas heating stoves, this appl cation being a division of my pending application Serial No. 88,753, filed February 1926, which has matured into Patent No.

1,719,994, dated July 9th, 1929.

The object of the invention is to providea burner and mixer for the fuel of a character I particularly adapted for a stove of the peculiar design set forth herein.

In the accompanying drawings:

Fig. 1 is a front elevation of a stove em,-

bodying my improvement.

Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view on the line 33 of Fig. 1. r p

Fig. 4 is a sectional view on the line of Fig. 3.

Fig. 5 is a detail plan view of the burner,

mixing chamber and mixing valve.

Referring to the drawings, 1 represents the base of the stove of curved form.

The 1 forwardly disposed chamber 12, disposed in rear ends of this base are connected to ver;

tical standards 2 and the forward porti on of ments.

This support consists of a curved shaped portion 5, concavo-convex in cross section, an lnner projecting shelf 6, an intermediate shelf 7 and a rear cross bar 8. intermediate shelf 7 forms a support The for a series of heat elements 9, which are known as radiants, while the shelf 6 forms a support for a curved back wall 10 of fire-proof material. This back wall 10 has at its uppe r end an integrally formed overhanging portion 10, the forward edge of which is of curved form. The radiants 9 are formed of proof material and are of a type well known in the art of gas heating stoves. These radiants are held in position by a flange 5 formed at the juncture of the portion 5 'andshelf 7 and also by a groove formed on the under side of the portion 10, as indicated in dotted lines at 10". The fire back 10 is held in position by forming therein grooves 11, which grooves engage the inner projecting edges of the standards 2 as shown in Fig. 3.

As clearly shown in Figs. 3 and 4 a j acket application filed Kay 85,

plate-20 of usual form is secured to the rear facesof the uprights 2, and by reason of the particular connection of the ends of the substantially semi-cylindrical fire-back 10, no portion of the fire-back contacts with the jacket plate, the space between the fire-back 10 and jacket plate 20 providing for. circulation of air therebetween so the stove maybe set close to a house wall without danger of setting fire to the same due to theheat radiating from the fire-back, when the stove is in use.

A cap 4 of ornamental appearance'is laid on the overhanging portion 10 of the fire wall, the upper end of the jacket plate 20 and on the upper ends of the standards.

The curves upon which the support, back Wall, and overhanging portion are formed are such that the radiants at each end of the series are located on the arc of a circle of smaller radius than that of the intermediate radiants.

The burner which employ consists of a a'curvilinear direction corresponding to that of the radiant support, arear chamber 13, two hollow arms 14 connecting the twochambers, a hollow memberv'l5 connected at its rear end with the chamber 13, and a fuel and air mixing valve 16 connected with the forward endof the member 15. Thechambers 12and 13 and the arms 14 are preferably integrallyformed while the member 15 is bolted to the flanged open'bottom of the chamber Theburner thus formed is connected with ears 17, projecting from the rear edge of theshelf 6, and is alsofastened to the standards2 and to bosses formed on its rear side of the cross-bar 8. The chamber 12 is disposed beneath the radiants Qand is providedwith a series of nozzles 18, one 01 each radiant, which are screwed into openings 18 in the upper wall of the chamber 12. It Will be notedthat the passage in the member 15 divergestoward the. mixing chamber, while the passages in the members 14 con verged from the chamber 13 to the chamber 12. This allows the air and gas to enter the mixing chamber in an expanded condition 'to secure a more thorough mixture, and to be then again contracted beforeentering the 7 burner chamber 12 to give it the proper density for eflicient combustion.

Having thus described my invention, I claim:

1. In a burner for a gas heating stove of the type which has a series .of exposed heating elements arranged in the open front of V the stove in a curvilinear series, with the elements at each end'of the series arranged on the arc of a circle of shorter radius than that of the intermediate elements, the combination of a burner member having a chamber arranged beneath said heating elements extending in a curvilinear direction with the ends thereof each formed on the arc of a circle of shorter radius than the intermediate portion thereof to conform to the curvature of the heating elements, and a plurality of noz- 'zles carried by said chamber, .one :for each heating element.

2; In a burner for .a gas heating :stove of the type whichhas a series of exposed heating elements arranged in the open front of the stove inva curvilinear series, with the elements at each end of the series arranged .on the arc of a circle of shorter radius than that of the intermediate elements, the combination .of a

burner member consisting of a rear chamber, a forward chamber, said forward chamber being arranged beneath said heating elements extending in a-curvilinear direction with the ends thereof each formed on the arc of a circle of shorter radius than the intermediate portion thereof to conform to the V curvature of the heating elements, and a pair elements arranged in the open front of the less in length than an-endless structure of the stove in a curvilinear series to present a convex heating surface, the combination of a arranged in a curvilinear direction'beneath said heating elements and being considerably same curvature and having its ends closed, a pair of communicating passageways extending from said rear chamber to said for ward chamber, a gas supply passage extending rearwardly in communication with said rear chamber, and a gas andair valve connected with said last mentioned passageway and located adjacent the forward portion of the stove.

4. In a burner for a gas heating stove of a the type which has a series of exposed'heating elements arranged in the open front of the stove in a curvilinear series to present a con vex heating surface, the combination of a burner consisting of a rear chamber, a forward chamber, said forward chamber being arranged in a curvilinear direction beneath said heating elements, a pair of communicatin passageways extending from said rear chain er to said forward chamber, said passageways diverging from said rear chamber tosaid forward chamber and forming communications between said chambers, each of said passageways being converged from the rear chamber to the forward chamber, a fuel supply diverging passageway leading to said rear chamber, and a gas and air valve controlling said last mentioned passageway and located adjacent the forward portion of the stove.

In testimony whereof, I have hereunto set my hand this 24th day of May, 1929. Y Y JACOB M. OLINGER.
