GAS BURNER.

Application fl1ed Ju1y 24, 1924. Serial No. 727,879.

To all whom it may concern.- i Be it known that BERRY A. BAXTER, a citizen of the United States of America,residing at Mansfield, in the county of Richland and State of Ohio, has invented certain new and useful Improvements in Gas Burners, of which the following is a specification.

This invention relates to gas burners.

It is well known to those skilled in the art that in the use and operation of gas heaters especially of the radiant type, that more perfect combustion can be had if means are provided for so mounting and supporting the'radiants that free circulation of air will be permitted around the burner between the. bottom of the radiants and the top of the burner tips.

The primary object, therefore, of the present invention is to provide means for mounting and supporting the radiants of the heater in such a manner as to permit free circulation of air around the burner between the top of the burner tips and the bottom of the radiant and also to provide means for retaining the bottom of the radiants in alignment and in a central position relative to the burner jets.

A further object is to provide a burner and so apportion the jets of the burner tips that the pressure of the gas will be equalized so that the flame of the burner will project up to the same height and to burn within and around the radiants uniformly from the jets in the tips.

Another object of the present invention is to provide means to choke or restrict the lower passage through which the air and gas mixture passes forming a neck-like portion or the like to confine and restrict the mixture therethrough, whereby the mixture of gas and air are brought and merged together to make more perfect mixture, thereby providing means for better combustion of the mixture.

A further object is to provide means whereby the burner tips can be inserted in suitable apertures in the burner and held properly positioned therein through the medium of tongue-like flanges with the aid of one screw which serves to securely fasten two burner tips securely to the top of the burner.

A further object is to provide means of constructing a burner of sheet metal whereby the cost of construction in labor and material is reduced and providing a smooth and unobstructed interior and exterior thereby reducing the friction of the flow of the; mixture through the passages of the burner and also providing a burner with a smooth and unobstructed surface for enamelin' or the like for finishing purposes.

ith these and other objects in view the lnvention resides in the features of construction described and the principle on which they operate, arrangement of parts and combination thereof, which will herelnafter be fully described. A structure which is the preferred embodiment of this mvention is clearly illustrated in the accompanying drawing forming part of this specification, in which: 1

Figure 1 is a side view of the burner of the burner which is preferably made of,

sheet metal and of hollow construction to provide passage-ways for the flow of air and gas to the burner tips 3, which are preferably-providedwith openings or jets 4. The lower part of the burner 1 is pressed or crimped inwardly to form a restricted or small passage for the gas and air at the point indicated at 5. The end of the lower portion 6 is provided with a mouth to provide for full and free admission of air so as to permit it to thoroughly mix with the fuel supplied from the source of supply as indicated at 8.

A partition member or plate 9 is interposed between the burner parts 1 and 2 thereby forming separate and distinct passage-ways for the fuel and air between the upper and lower parts 1 and 2. The partition plate is inwardly ressed or crimped as indicate at 6 toward t e int indicated at 5 of the lower portion 1 t ereby restricting the passage-way formed by the lower part 1 of the burner and choking (or restrictmg) the free flow of fuel and air and at this point forming a neck-like passage-Way between the plate 9 and the lower part 1.

It will be noted that at the points 5 and secure the upper and ower 6 the plate 9 is provided with sides 10 and 11, whiclrwith the bottom 12 of the plate forms a trough-like ortion. In order to rtions 1 and 2 of the burner together and iaving the plate 9 interposed therebetwen, without the use of the rivets or screws, fastening means are made integral with the top and low pertions 1 and 2, as follows:

The edges of the part 2 have loops 13 and 14 formed thereon with the openings extending in opposed relation toward the interior of ,the portion 2. The portion 1 has outwardly extending

flanges

15 and 16 fitted within the loops 13 and 14 and the plate 9 is also provided with outwardly extending

flanges

17 and 18 WlllCh are fitted within the loops 13 and 14. The loops 13 and 14 are then beaded or pressed together holding the bottom portion securely connected to the upper portion 2 with the plate 9 interposed therebetween, thereby providing a burner with an upper and lower passage-way for the mixture of air and gas.

The u per portion of the burner 2 is also provide with a series of apertures 19 which are preferably formed rectangular in shape; Each burner tip 3 is provided with a flange as shown at 20 and it is adapted to be fitted to the aperture 19 formed in the top portion 2 of the burner. Preferably at each corner of the burner

tip supporting members

21, 22, 23, and 24 are formed integral with the burner tip and preferably extend up on a plane or above the top of the jets 4 of the burner as indi-.

cated at 25. Extending vertically therefrom lugs 26 are provided and preferably made integral with, the supporting mem- The lugs 26. are adapted to fit within the bottom of the radiants 27 to position, retain and maintain the radiants in a central position over the jets as stated. The supporting members support the radiants in such a manner as to permit of free circulation of air around the radiants and jets between the bottom of the radiants and the top of the jets. As the top of the jets. of the burner tip are rounded as shown in Fig. 5 at 28 and 29 air can circulate freely around the burner jets and bottom of the radiants even though the bottom of the radiants are slightly below and on a plane with the top of the jets.

Attention is called to the fact that the fuel mixed with air passes through the passage-way inthe lower portion 1 of the burner in the first instance and then passes up and into the passage-way of thepart 2 flowing into the passage-way at the flush ends of the body portions of the burner 2 with more velocity or pressure near the cap 30, therefore the flames emitting from tneburner tips burn stronger and the flames tical direction than at the ends of the burner portions near the plate 31. In order,

therefore, to re ulate the flow of the mixture so that 1t will be more uniform throughout the series of burner tips and to counteract the pressure at the flush end of the burner, the jets 4 are made less in number or smaller in size or area in the first two burner tips adjacent to the flush ends of the burner portions covered by the cap 30. In other words as shown in Fig. 1 there are five (5) jets formed in the first burner tip, six (6) in the second tip and seven (7) 1n the remaining tips. The .construction of the tips, as described, has the effect of retarding or stopping more or less of the quantity of mixture that would ordinarily pass through the conventional jets on account of the decreased size of the jet openings, or of the decreased number of jets formed in the tips adjacent to the end where the pressure is greatest and allowing an equal quantity of mixture to pass through the conventional jets of the other tips, where the pressure is not so reat.

The cap 30 is fastened to one on of the lower parts 1 and 2 of the burner and the plate 31 is fastened to one end of the upper part 2 of the burner by a through-going bolt 32 and a nut 33.

From the above description it will be noted that the body of the burner is composed of but three (3) parts, a lower portion, an upper portion and an intermediate partition plate, which is interposed between the upper and lower portions. It will also be noted that all of these parts are held in their assembled position through the medium of flanges by the beading method, which requires no rivets, bolts, screws, welding or the like.

It will also be noted that a neck-like portion is formed. in the lower part Lof the burner at a predetermined point in the passage-way to force the gas and air to mix and merge more thoroughly together on account of the confined passage-way, and then allowing the gas and air to spread more or less and flow into the upper passage-way formed in the part 2 of the burner, to the burner tips.

Attention is called to the fact that the burner tips are secured to the top part of the burner 2 in a novel manner as follows:

A tongue-like flange 34 is formed integral therewith and is adapted to underlap the top portion of the burner as shown in Fig. 1. I

noted that these flanges are made integral with the burner ti s and extend from the burner tips on a .di erent plane. They further serve to hold and maintain the burner tips in position. I The tongue-like flanges that extend over the top surface ofthe top of the burner on each pair of tips extend inj'uxtapositionor toward each other, so that one screw 36. holds two (2) of the burner tips securely in place. The preferableconstruction of the burner and tips of the burner is of sheet metal so as to afford a smooth and polished surface for enameling purposes, which smooth surface also obviates the friction of the gas and air in passing through the burner.

It will be noted, however, that the burner can be made of cast metal if desired without departing from the spirit or principle .of the invention herein described.

Attention iscalled to the fact that this burner can be constructed upon an economical basis, asto labor as well as material.

It is not intended to confine the invention to the structure shown in the drawing as many immaterial alterations or changes may be made, in the structure without departing s from the spirit of theinvention.

I claim: I

1. A gas burner of the radiant type, comcomprising a section formed for the passage of gas therethrough, means integral with the tip for directly receiving and sup orting the radiant, and upstanding lugs to directly cooperate with the radiant at spaced points to maintain the radiant in position over the tip, the upper surface of the tip between the lugs being rounded to permit the entrance of air beneath the edges of the radiant when in position on such tip.

In testimony whereof I afiix my signature.
