Application filed March 8, 1923. Serial No. 623,716.

To oZ/T whom it may concern:

Be it known that I, EUGENE ORA DANIELS, a citizen ofthe United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Gas Burners, of which the following is a specification, reference being had therein to the accompanying drawing. 7

This invention relates to certain new and useful improvements in gas burners especially adaptedtobe used in connection with stoves, furnaces and the like and is an improvement upon my gas burner as shown in my application filed January 3, 1923, Serial Number 610,462, the object being to provide a gas burner with a. numloer of mixing chambers corresponding in' number to the flame spreaders used so as ,to superheat the airand gas before they are mixed to obtain perfect combustion by converting the moisture contained in either the air or gas into a gas which is consumed, thereby eliminating the forming of soot and the like and providing a construction of burner which is very economical in use.

Another and further object of the inven tion is to provide novel means for constructing a burner of several parts which are so connected that the parts are interchangeable,

extension nipples belng provided for carrying theflame spreaders to enable the burner to be. adjusted to fit various size stoves, furnaces and the like. i

Another and further object of the invention is to provide novel means for holding the extension nipples carrying the flame Spreaders in position so as to prevent the same from turning or moving.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by g the appended'claims.

In the drawings,

Figure 1 is an inverted plan view of a stove, furnace or the like in any desired manner, such as upon the grate or upon a supporting base of any kind or supported in various ways as the particular manner of supporting the burner within the stove is lmmaterial as I am aware that the same can be supportedin various ways without departingfr'om the spirit of my invention.

The hub 1 at its upper end is provided with an annular inwardly extending flange 4 which is notched as shown at 5 for the pur- I posehereinafter fully described.

Arranged within the hollow hub is a cap 6 having radial web portions 7'forming in con unction with the hollow hub a plurality of air and gas mixing chambers which reg- I isterwith the hollow tubular' arms 2, said cap being provided with a threaded stem 8 which extends above the upper end of the hub 1 and is secured in position therein by a nut 9. In order to position the cap 6 within the hollow hub, the stem 8 is provided with proextending projections 11 which are cut away as shown at 12 and are provided with bores 13 forming fuel passages through which the gas passes from thecentral chamber 14: of the cap 6, said chamber being supplied with gas by a' supply'pipe 15 screwedinto athreaded bore 16 formed in the bottom of the cap as clearly shown in Figure 2.

Arranged within each of the tubular arms 2 is an extension nipple l'l, the inner end of which is notched as shown at 18 engaging the projection 11 for preventing the nipple from turning within the tubular arm 2, said arm being provided with threaded bores 19 carrying screws 20 for locking said nipples in adjusted position, each nipple carrying a segmental flame spreader 21 at its outer end in which the threaded outer end of the nipple is secured.

By adjusting the length of the nipples, the size of the burner can be increased or decreased in order to enable the burner to be made to fit the stove or furnace in which the burner is to be used.

In use I preferably arrange a lid 22 over the ring and hub as shown in Figure 2 and while I have shown the use of a lid, of course, I do not wish to limit myself to a burner using the lid as I am aware that the particular construction of burner herein shown will operate without the lid, but I have found that-the heat is confined in the ring by the burner so as to preheat the air and gas to a reater degree when the lid is employed. the draft is poor, more air is forced to and through the mixing chamber so as to supply the necessary oxygen in order to obtain a perfect combustion.

Vhen the burner is in position within a stove and supported in any desired manner, the gas entering through the supply aipe 15 is discharged into a central chamber 1% of the cap and is discharged therefrom through the spuds formed by the projectior 11 and bores 13 into the respective mixing chambers from which the mixture passes through the spreaders and against the wall of the stove or furnace and consumed.

By this particular construction I am able to preheat the air and gas and to produce a mixture very economically so as to obtain the best results.

What I claim is l. A gas burner comprising a hollow hub provided with radial tubular arms carrying a ring at their outer ends, said hub being provided with an annular flange at its upper end, the inner wall of which is provided with oppositely disposed notches, a hollow cap arranged within said hub having a threaded stem provided with oppositely disposed projections fitting in the notches of said hub, a nut working on said stem for securing said cap within said hub, said cap being provided with radial web portions and intermediate projections provided with bores, supply pipe connected to said cap for supplying fuel thereto, tubular nipples mounted in said arms having notched inner ends to receive the projections of said cap, flame Spreaders carried by said nipples and means for locking said nipples within said arms. I

2. A gas burner comprising a hub member having radial tubular arms carrying a ldy the use of the lid, when ring at their outer ends for connecting said arms together, said hub having an annular flange at its upper edge, a cap member arranged within said hub member having a threaded stem, a nut working on said stem for securing said cap member within said hub member, a lid arranged over said ring, said cap member being arovided with radial web portions and intermediate projections forming a plurality of mixing chambers registering with the tubular arms, said projections being provided with bores form- ,4 gas spuds, nipples mounted within said tubular arms carrying flame spreaders at their outer ends and a gas supply pipe con nected to said cap.

3. A gas burner comprising a hub member having radial tubular arms connected together by a ring at their outer ends, Said hub member having an annular flange provided with oppositely disposed notches, a hollow cap member arranged within said hub having a threaded stem provided with oppositely disposed projections registedng with said notches, a nut working on said stem for securing said cap in position within said hub member said cap being provided with radial web portions contacting with the inner wails of said hub to form a plurality of mixing chambers registering with the tubular arms of said hub and terminating short oi": the lower edge of said hub, said cap member being provided with intermediate radial projections provided with bores forming spuds, a supply pipe connected to said cap member, nipples mounted in said tubular arms having bell shaped ends provided with notches registering with said projections for preventing said nipples from rotating within said tubular arms and flame spreaders carried by the outer ends of said nipples.

In testimony whereof I hereunto affix my signature.
