This invention relates to gas burners and Supports therefor, and has special reference to burners for use in cooking ranges and stoves.

Objects of the invention are 'to provide pipes of improved construction for conducting the gas from the manifold to the burners, and improved means for supporting the burners in one position for natural gas and in another position for manufactured gas.

Other objects will appear from the following description, reference being made to the drawings in which A Fig. 1 is a plan view of a stove having my improved burners mounted therein. 1

tion isdivided from my prior application 5 for stove, filed August 3, 1928, Serial No.

A gas supply pipe 1 opens into a mani fold 2 at thefront of the stove and has valve devices 3 for controlling and regulat ing the passage of gas from the manifold 2 to burners which are in connectionwiththe pipes 4and 5 each consists of a central hol- .low annular portion 8 and a series of radial arms 9; opening from the annular portion 8. The annular portion 8 and the arms 9 have through their upper walls numerous gas outletoningslilu Theburner '3' is ahollow chamr having through'its upper .wall a I and burner supportsnumber of gas outlet openings 11. These burners are all mounted in a proper order and relationship in a burner box frame 12 which is equipped with a suitable grid (not ral gas are known and are not shown in the drawings.

Each pipe 4 is of increasing horizontal diameter from its front end to its union with one of the arms 9. Said pipe 4 is integrally united with and opens into the end and the under side of the arm 9. The inside horizontal diameter of the pipe 4 at its union with the g arm 9 is the same as the inside diameter of the Figs. 4 and 5 are top plan and side eleva-' 5) away from .the upper wall of the burner arm 9 so that the vertical diameter of the arm '9 into which the pipe 4 opens increases from the end inwardly. The upper wall of the pipe The subject matter-of. the present inven- 4 is a very slight distance below the upper. I

Thus the pipe 4 together with the burner arm 9 with which it is connected forms an enlarged chamber, the horizontal'diameter of which is the same as the horizontal diameter of the unitedportions of the pipe 4 and the burner arm 9, and the vertical diameter of which chamber is greater than the vertical diameter of the pipe 4. Moreover the vertical diameter of the chamber 9'increases from its outer end toward .its inner end. l'his construction obtains'a superior mixture of air. and gas by combustion of which greater heat is obtained than is obtained by the use of other types of burners "with which I am familiar.

Iii their construction and their connectio with the arms 9 of the respeetive burners the pipes are quite similar tothe construction and connection of the pipes 4 with the burner arms 9. That is to say, the pipes 5 open into the ends and under; sides of the arms 9 with which said pipes are connected, being of the same inside horizontal diameter as the arms 9 and of greater vertical diameter. The lower vertical diameter of the pipe 5 and greater than any of the remaining burner arms 9. These pipes 5 are provided with curved extensions 14 at theiriinner ends so that the burners in" connection with the pipes 4 may be made in front of the burners in connection with the pipes 5. In this arrangement the pipes 5 are between the pipes 4.

When manufactured-gas is to be used as a fuel the burners are supported in a higher position in the burner box when natural gas is used as a fuel. The support for each of the rear burners comprises a bifurcated supporting bracket element 15, the ends of the arms of which are removably seated in depressed portions of lugs 16 projecting from the inner side of'the rear portion of the burner box frame 12. Each of the rear burners has an integral projection 17 from its rear arm for attachment with the adjacent supporting bracket to which it is secured by a stove bolt 18. When. natural gas is to be used as a fuel the projection 17 is fastened on the under 'side of the supporting bracket 15; and when manufactured gas is to be burned as a fuel the projection 17 is fastened on the upper side of the supporting bracket15, thereby supporting the burners at a higher altitude in the burner box frame when manufactured gas is burned as a fuel than when natural gas is burned as a fuel.

The support for the burner 7 comprises an arm 19 which is fastened on a lug 20 projecting from the adjacent side of the burner box frame 12 and secured thereto by a stove bolt 21. When'natural gas is to be burned as a fuel the arm 19 is fastened on the under side of the supporting lug 20; and when manufactured gas is to be burned as a fuel-said arm 19 is fastened on the upper side of the supporting lug 20, thereby supporting the burner 7 at a higher altitude in the burner box than when manufactured gas is burned as a fuel.

The pipes 5. support the front burners. Each pipe 5 has an arm 22 projecting laterally and provided with a hole 23. The rear arm of each of the front burners is formed with a flange 24 and with a depending ing 25. The lug 25 is for engagement in the hole 23. Rib 26 is integral with the under side of the flange 24 and seats upon spaced lu s 27 on the upper side of the arm 22. e front ends of the ipes 4 and 5 are raised or lowered as the inner ends' of said pipes are raised or lowered toadapt the burners for use of manufactured or natural gas. The specific means for supporting the front ends of these pipes in different altitudes conforming to the positions of the burners is not shown, as said specific supporting means for the front ends of said pipes is no part of the present invention. It will be understood, however, that the positions of the pipes 4 and their burners are controlled by the positions of the pipes 5.

The rear wall of the burner box has an outlet opening 28. A plate 29 is mounted for sliding movements in guides 30 and is capable of movements in said guides to positions to open and to close the opening 28. When natural gas is burned as a fuel the opening 28 should be kept open in order to permit the fumes to pass out and this con- (ition may be maintained by keeping the plate 29. in open position. However, when manufactured gas is used, it may be unnecessary to keep the plate 29 in open position all of the time.

This outlet opening 28 is above the wall 31 which forms the top wall of an oven 32 and the bottom wall of the burner box. A connection for a stove pipe is provided, the same comprising a pair of side walls 33, a rear wall 34 and a flange 35. The flange 35 is attached to the rear wall of the stove by bolts 36 so that said walls33 and 34 form a passage to receive the gas fumes dischar ed from the burner box through the opening 28. A ring 37 is fastened to the upper end of the part comprising the

walls

33 and 34 by a bolt 38 and is provided with an upwardly extended flange 39 on which the lower end of the stove pipe 40 is telescoped. The stove pipe 40 seats upon the ring 37 and opens into a main stove pipe 41 which, in the embodiment shown, constitutes a smoke outlet from another part of the stove.

The plate 29 is freely movable to open and to closed positions along the guides 30 and is formed with a handle 42 whereby it may be conveniently moved from one position to another. Accordingly, my invention is well designed to use natural gas or manufactured gas as fuels.

I From the.foregoing it must be apparent that I have produced a new and improved type of burnercapable of satisfactory use in burning either natural gas or manu actured gas as fuels. These burners are assembled in a novel relationship to each other and to the cooperating stove structure. This stove in which these burners are embodied is easily capable of adjustment to burn either kind of fuel. The construction and arrangement may be varied within equivalent limits without departure from the nature and principle of the invention.

I claim I 1. In a gas stove, a hollow burner compris- 5 7 ing' hollow radial arms, in combination with a pipe for conducting gas to said burner, said pipe being of increasing diameter from its outer end to integral connection with one ofthe arms of said burner at the inner end of said pipe, the inside horizontal diameter of the pipe at its connection with said arm being equal to the inside horizontal diameter of the arm and thevertical diameter of the pipe at-its connection with said arm being greater k than the vertical diameter of the remaining arms of the burner, the upper wall of the 1 pipe at its connection with said burner arm eing s'lightl below theplan'e of the upper wall of said urner arm and the lower wall of "the pipe inclining downwardly and inwardly throughout nearly the entire length of the burner arm. p 2. In a gas stove, a hollow burner comprising hollow radial arms of approximately the same horizontal diameter, in combination with a pipe for conductinggas to said burner,

said pipe being of increasmg diameter from its outer end to integral connection with one of the arms of said burner at the inner end, of said pipe, the inside horizontal diameter of said pipe at the union thereof with said arm of said burner being approximatel the same as the inside horizontal diameter 0 said I arm.
