HENRY W. ODOWD, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO WILLIAM M. CRANE COMPANY, A CGB/PORATION OF NEW YORK.

ens-strove.

Application filed June 1, 1918.

To all whom it may concern Be it known that I, HENRY W. ODowo, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have made certain new and useful Improvements in Gas-Stoves, of which the following is a specification.

The invention relates to heating apparatus, and more particularly to gas stoves having skeleton tops with burners arranged beneath the same. i

Objects of the invention are to provide a construction of the character referred to which shall be highly eiiicient and economical in construction and operation. These and other objects of the invention will in part be obvious and in part more fully set forth in the following description.

The invention consists in the novel parts, improvements, combinations and features of construction hereinafter shown and described.

In the accompanying drawings, which are referred to herein and form part hereof, is

invention, the same serving in connection with the description herein to explain the principles of the invention.

. Of the drawings Figure 1 is a top plan of an embodiment of the invention; and

Fig. 2 is a view partly in front elevation ipd partly in section upon the lines 2-2 of A gas stove constructed in accordance with certain features of the invention includes, in combination, a burner having a plurality of flame members disposed at angles to each other and a top having spaced apart members arranged above and between said flame members. In one embodiment of this feature of the invention a star burner is provided and the bars of the skeleton top have deflected portions extending above and between the flame members.

In accordance with another feature of the invention there are provided in the top of the stove additionally spaced-apart members arranged above and in registry with flame members but not extending thereover.

Referring now in detail to the drawings, there is illustrated therein a preferred embodiment of the invention, the same comprising a frame 3 suitably mounted upon legs 4. While the stove may be of any desired form, preferably and as shown it is Specification of Letters Patent.

Serial No. 237,706.

rectangular in shape and is of the open or skelton-top variety, the top having spaced apart members or bars, to which further reference presently will be made.

It will be noted that the invention is of such a nature that it may be embodied in batteries of units, that is to say, complete stoves or units may be combined, the combination having certain advantages, as that of increased capacity and of rendering unnecessary the duplication of certain parts, for instance, the legs l. These advantages of combination and the parts, the duplication of which is thus rendered unnecessary, will be apparent to those skilled in the art as the invention is described.

While burnersof divers shapes and kinds may be employed, preferably and as shown, each stove or unit is provided with a star burner 6 whose arms or flame members 7, having nozzles 8, are spaced apart each at an angle to the others excepting its oppositely placed member. Each burner is provided with the usual Bunsen tube 9 to which the gas is furnished by a main supply pipe 11, the usual cocks 12 being provided.

As stated, the top of each stove is of the open or skeleton type, bars 13 extending, preferably, longitudinally of the top and being suitably spaced apart and located a suitable distance above the burner. It will be seen that when a vessel is placed upon the bars 13, the heated products of combustion arising from the burner will flow through the passages created by the bars '13 and the bottom of the utensil or vessel placed upon them, heating the vessel in their passage to the atmosphere. If the vessel placed upon the bars 13 is of a size to extend quite to the ends 1a of the bars 13, the free spaces between the said ends 14 will permit the escape of the products of combustion.

A. prime feature of the invention consists in providing means whereby disturbances or cross currents in the flow of the heated. products of combustion are avoided, and a steady, uninterrupted, even flow of the said products of combustion is insured, thus maintaining combustion at its best and imparting the greatest amount of heat to the utensil or vessel and its contents to be heated. To this end, therefore, and preferably and as illustrated in the drawings. means are provided above and in the vicinity of the burner for organizing currents of the heated products of combustion and directing them so that they will flow out between the bars 13 of the top.

While various instrumentalities may be used for this purpose, preferably and as shown, bars 13 to the required number are deflected from their longitudinal paths so as to form extensions 18 between the flame members 7 of the burner.

In the preferred embodiment of the invention shown in the drawings, also, certain others of the bars 13, being four in number in the particular embodiment of the invention illustrated, are deflected from their longitudinal paths to form extensions 19 each in line with a flame member 7 of the burner. It will be seen that the heated products of combustion arising from the flame members 7 of the burners will be confined between the extensions 18 and 19 of the bars 13, thus forming currents which will pass from between the said extensions out through the bars 13 to the atmosphere, and the said extensions 18 and 19 will be continued in the direction of the burner far enough to insure the accomplishment of this function. To lend rigidity to the members 13 and their extensions 18 and 19, in the preferred embodiment of the invention illustrated, connections 21 are provided between said members and extensions at suitable points, as shown in the drawings, being disposed so as not to interfere with the flow of the currents of the heated products of combustion. In this embodiment also the frame is stiflened by the bars 22 suitably secured, as at points 23. i

The invention in its broader aspects is not limited to the precise construction shown and described, nor to any construction by which it has been or may be carried into effect, as many changes may be made in the details without departing from the main principles of the invention or sacrificing its chief advantages.

I claim: i

1. A stove including a frame comprising oppositely disposed side and end sections, stiffening members disposed between the sections, burners associated with said stiffening members, a plurality of spaced-apart bars arranged in approximate parallelism longitudinally of the frame and supported at their opposite ends on certain of the sections, the top edges of the bars being in the same plane and above the plane of the sections upon which they rest at their ends, and a plurality of extensions on the other ends of said bars disposed in angular relation thereto and projecting in the direction of the burners whereby, when the top is covered by a cooking utensil, they deflect products of combustion outwardly between the bars which constitute, with the cooking utensil, channels to guide the heat currents toward the end of the sections.

2. A stove including a frame comprising oppositely disposed side and end sections, stiffening members disposed between the sections, burners associated with said stiifening members, a plurality of spaced-apart bars arranged in approximate parallelism longitudinally of the frame and supported at their opposite ends on certain of the sections, the top edges of the bars being in the same plane and above the plane of the sections upon which they rest at their ends, and a plurality of extensions on the other ends of said bars disposed in angular relation thereto and projecting in the direction of the burners whereby, when the top is covered by a cooking utensil, they deflect products of combustion outwardly between the bars which constitute, with the cooking utensil, channels to guide the heat currents toward the end of the sections, certain of said extensions being carried into approximate alinement with the end of the burners, and others of said extensions extending between the burner sections.

In testimony whereof, I have aflixed my signature hereto.

HENRY ODOVVD.
