*To all whom' 1' t may concern Be it -known that LVFRA-Nii'IEQSEELELa citizen -ol the United States, residing-at Port Chester, in the county ofVestcliester andsState of New York,v have invented 4new andY useful 'Improvements l'in Gas lRar-iges,

lunfnerupward about the lower endet a vessel or lreceptacle placed"` in a iliole or aperture in the top above-the? burner. `Also it is'ffound thatwhere a-plurality of'liurners are provided, the-'flament :thosenearfthe rear of the stove is frequently {deiectedflaty erally bythe rearwardly lmoving current; of

the products ofcombustion from v'a 'front burner or burners.

`The i particular obj eets` of the present;v Tinvention are'toprovidea simple butt-very effective means for :directingathe.fflame .of each burner-of a gas range Aupwardianfdapro Itecting it from being affected'.` by;l the action Vof another burner or burners Ior f the @current of products of combustion therefrom.

With these and other.objectsinaviewA the invention resides in the particular,.construction andkarrangement of parts that will be hereinafter pointed Aout and claimed.

lt is to be understood that in the accompanying drawing some of the parts are shown more or less conventionally and there can, of course, be considerable variation in the details of construction shown without departing from the invention.

In the accompanying drawings:

Figure l is a plan of a gas range embodying the present invention, a portion of the top plate being broken away above one of the burners.

Figure 2 is a transverse vertical section, on a slightly enlarged scale.

Figure 3 is a detail, sectional view, of a slight modification of the embodiment illustrated in Figure 2.

Referring to the drawing, in which like reference characters designate corresponding parts in the several views, l designates a portion -of the'frameof agas range, and 2 designates the :top or cover plate whichis .mounted on saidframe overthe burnersv `3.

Arlheframe may, of course, be of any suitable size andfform, including either elevated ovens or oven chambers arranged below the top 2 and the-latter is, `as usual, provided with Va plurality of openings or apertures,

one above each burner, adapted to'receive a cooking vessel or utensil;

iIn the embodiment of the' invention illustrated'the top plate 2 is provided with an integral. marginal skirt or flange 4 that extends downward andforms asubstantially vertical wall extendingvaroundthe. space in which the burners-13 .are supported.

-The lower edge ofthe marginalange 4 of the topzis preferably in substantially. the horizontal plane of the main gas supply pipe 5,*and the branchpipesA connecting the Amain supplyV pipe' withy each. of the burners Sextend through mixing valves '7 thaty arerembraced: by recesses formed. in the lower edgeofsaid flange. A ksuitable cutofifvalvefS is provided foreachfburner pipe 6 in the ordinary manner.

As shown,a grid or apertured supporti) is arranged `within each ofthe utensilrre- .eeiving openings in the topplate, andy .such

.openings are closed byimperforateplates lO. These features, however,do notconstitute La` part ,of thepresent. invention, and, Vtherefore@ are fnot ldescribed kmore 1n vdetail herein.

.As shown in Figure -l,.the fforward burners and.A .the cooperating utensil receiving apertures or openings in the top plate 2 are considerably larger than the corresponding burners and openings in rear thereof. It will also be noted that the centers of the burners and said openings in the top plate 2 are not in the same plane or line extending from the front to the rear of the stove. That is, the smaller, rearward, burners and apertures are o'set laterally from the lines including the centers of the front burners and openings. This arrangement provides a passage for the products of combustion from the forward burners to the outlet l() of the burner chamber, which passage is of greater Width at its rear end than between the forward burners. Therefore, the currents of the products of combustion from the front burners to said outlet 10 will not affect the-Haine of the rear burners to the same extent that they would if the said rear burners were in substantially longitudinal alignment with the front burners.

Additional means hereinafter referred to are also provided for preventing the currents of the products of combustion from the front burners interfering with or affecting the flame of either of the rear burners. t Y

As shown, each of theburners consists of a suitable body, shaped, as usual, to provide a series of radially projecting arms having perforation in their upper faces, although there can be variations in the designs of this burner with-out departing from this invention. Each burner is provided with an upwardly extending guard or stack 11. The guard 11, as shown, has at its upper end au outwardlyT projecting flange 12, which extends laterally beyond the body of the burner. The guard may be of cast metal or any other suitable material, and of any suitable form. As shown, it extends continuously around the burner and forms a short stack extending above the burner openings so that the flame and products of combustion from the burner will be initially directed upward. The walls of the guard 11, 12, extending above and outwardly from the burner openings prevent the flame of the burner from being seriously affected by moving drafts or currents through the space or chamber in which the burners are arranged and thus aid in insuring perfect combustion of the mixture being burned.

Instead of providing each burner with a separable guard 11, the burner body itself may have an integral upwardly extending marginal flange 13 terminating at its upper end in a lateral extension 14, as shown in Figure 8.

Preferably, although not necessarily, the guard 11 extends completely about the burner. Some of the advantages of the invention, however, may be obtained if such guard extends but partially about the burner, the location thereof being determined according to the direction from which objectionable drafts or currents are likely to approach the burner.

I claim:

1. In a gas stove, the 'combination with a burner chamber having an outlet for products of combustion, of a top plate covering said chamber and provided with four apertures, each adapted to receive a cooking utensil, all situated in transverse planes between said outlet and the front edge of the plate and arranged in two pairs positioned, respectively, adjacent the front edge of the plate and rearward thereof, and a burner below each said aperture, the members of the rear pair of apertures and the burners in alignment therewith being of smaller diameter than the apertures and burners of the forward pair and the centers of the rear pair of apertures and burners being spaced laterally a greater distance than the centers ofthe forward pair, whereby the flow of products of combustion from the forward pair of burners to the outlet is not obstructed by the rear burners.

2. In a gas stove, the combination of a top plate provided with four apertures, each adapted to receive a cooking utensil, arranged in two pairs positioned, respectively, adjacent the front edge of the plate and rearward thereof, and having an outlet for products of combustion adjacent its rear edge, and a burner below each said aperture, the members of the rear pair of apertures and the burners in alignment therewith being laterally separated to a greater errV tent than the members of the forward pair of apertures and their burners, whereby the flow of products of combustion from the front burners to the outlet is not obstructed by the rear burners.

In testimony whereof I have hereunto set my hand.

FRANK E. SEELEY.
