CLOSED-TOP GAS RANGE.

Application filed November 10, 1924. Serial No. 748,843.

This invention relates to improvements in gas ranges, and more particularly to those of the closed top type.

Up to the present time the closed top type of gas range has not been successful due to the fact that all of the burners do not re ceive an equal or adequate supply of fresh air to insure complete combustion, with a resultant inefficiency of operation. This is 3 especially true of the rear burners where a floating of gas under the lids is likely to occur.

The object of this invention is to provide a closed top gas range wherein all of the air necessary to insure proper combustion. A further ob]ect of this invention is to provide the rear burners with a separate intake for the fresh air and an outlet for the products of combustion.

A further object relates to the arrangement of battle plates whereby the separation of the incoming fresh air from the outgoing heated air and products of combustion is effected.

The figure in the drawing is a perspective view of the gas range with closed top, cut away to show how fresh air is admitted to the rear burners, and all products of combustion leave through the rear vent.

The general range structure is of the conventional type consisting of an oven, indicated by the numeral 10, and a range 11 adapted for burning gas as a fuel. The closed top 12, together with the sides 13, rear wall 14 and the drip pan 15 form a combustion chamber, constructed of materials of conventional type. Fresh air enters the front opening 16 of the chamber and takes the path indicated by full arrows.

The oxygen in the air is consumed largely by the forward burners 17 and 17. The heated air and products of combustion then take the path of the dotted arrows to the rear of the chamber and through the elbow 18 and vent pipe (not shown).

The rear wall 1 1 of combustion chamber 13 is provided with the vents 19 and 19. These vents supply fresh air to the rear burners 20, as indicated by the full arrows.

To insure an unadulterated supply of fresh air reaching the rear burners and to prevent said air from being withdrawn prematurely through flue 18, a pair of bafile plates 22 are extended outwardly at an angle burners receive an adequate supply of fresh and reach from the closed top 12 to the drip pan 15. These ballie plates serve to direct the fresh air to said rear burners, and also direct all of the products of combustion of the whole chamber up through flue 18. as indicated by dotted arrows.

It will be apparent from the above that the invention disclosed provides a closed top gas range in which all burners give equal service by reason of having a suiiicient amount of fresh air.

It will be obvious that the form of the invention described is shown, more or less, diagrammatically, and for the purpose of illustration only, and that changes may be made without departing from the spirit of the invention.

"What I claim is 1. The combination in a range, of a combustion chamber having a closed top, a drip pan, side-walls, a rear wall, said chamber being open at the front for the admittance of a fresh air supply, a plurality of burners in said chamber, and a plurality of air inlets in the rear wall for supplying fresh air to the rear burners.

2. The combination in a closed top gas range provided with a combustion chamber having side and rear walls, of a front and rear burner in said chamber, an outlet flue adjacent said rear wall for the escape of gases and products of combustion from said chamber, said range having an opening in the front thereof for supplying air to said front burner, one of said walls being provided with an opening for supplying fresh air to said rear burner, and a baffle interposed between said last mentioned opening and said outlet fine for causing the air entering said opening to flow to said rear burner before entering said flue.

3. A range comprising a combustion chamber having a front and a rear burner therein, a flue for carrying off the products of combustion from said chamber, an open ing for the admission of fresh air at the rear of said chamber, and a baflie plate projecting from the rear wall of said chamber to guide incoming air to said burner and outgoing gases to said flue.

Apparatus of the class described comprising a pair of front and a pair of rear burners, a combustion chamber common to said burners having a top, side, rear and bottom walls, said rear wall being provided witlran air inlet opening for-each of said rear burners, an outlet flue adjacent said rear wall between said inlet openings, a pair of battles disposed between the said topand bottom walls of said chamber, and each extending from said rear wall between said outlet flue and one of said air inletsin-a plane approximately tangent to the periphery of the corresponding rear burners and terminating adjacent the side thereof least removed from the corresponding side wall of said chamber, said baffles serving to direct the fresh air entering said openings to said burners, and to direct the products of combustion from both said rear and front burners to said outlet flue.

5. The combination in a closed top gas range provided with a combustion chamber having side and rear walls, of a pair of front and rear burners in said chamber, an outlet flue adjacent said rear wall for the escape of gases and products of combustion from said chamber, said range having an opening in the front thereof for-supplying, airto said front burners, one of said walls being provided with openings for supplying fresh air to said rear burners, and a pair of vertically arranged ba'fiies each 1nter-' posed'between one ofsaid last mentioned having side and rear openings and said outlet for causing the air entering said openings to flow to the corresponding rear burner before entering said flue.

6. The combination in a closed top gas range provided with a combustion chamber walls, of a pair of front and rear burners in said chamber, an

out-let fine adjacent said rear wall for the escape of gases and products of combustion from said chamber, said range having an opening in the front thereof for supplying air to said front burners, one of said walls being provided with openings for supplying fresh air to said rear burners, and a pair of vertically arranged baflies each interposed between one of said last mentioned openings and said outlet for causing the air entering said openings to flow to the corresponding rear burner before entering'said flue; said baffles being secured to said rear wall and converging in a direction toward said wall whereby said baffles also serve to direct the products of combustion to said outlet flue.

In testimony whereof, I have subscribed my name.

FREDERICK W. ROGERS.
