' ons BURNER.
This invention relates to a gas burner. More particularly it comprises a gas'burner of the type wherein 'air' is mixed with the gas at one end of 'said burner and the 'mixture consumed at the other end of said burner, certain vnovel features of rcoi'istruction insuring the'thorough mixing of they gas and air and the proper combustion ofsaid mixture; y f
In burners of this type, as heretoffn'econ`- structed, under'certain conditionsof low gas pressure `the flame yhas been found to snap 'back causing an explosion `within thepassageway for the 'mixture of gas *andan` and l5 the extinguishment of the llame yatlthe` yout.-
.side thereof. `Such actionof the burnerfis dangerous'in that' if' suchliame continues to burn underimperfect conditions of combusftion within the burner, poisonous gases would begenerated and if the liamelis ex,- tinguished altogether. the flow of gas through the apparatus' may resultv in an explosionor endangerlife through asphyxiation.l 0 The object of the presentinventlon 1sv to obviatel the'dangers above referred tof/and to provide a burner of simple construction which will insure thev thorough mixingof lthe gas and airy andftheir proper combustion at the orifice yof the burner. Afurther ob- 'jecty of the invention iste improve theenoz` zleend of the burner so lthat the samemay utilize a very lar e quantity of air and-produce perfect com ustion. yStillanother eb- `ject ofthe inventionis towsimplify the conrstruction so thatfa loose plate maylbe employed with a burner producingk a vertical llame and at the samel time providea ldevicewhich may be-readily inspected-and maintained in perfect operating condition. @ther objects ofy thel invention` vwill appear in the course of the following description. Tov thefaccomplishment of the foregoing and related ends, said invention, then, consists ofthe means hereinafter fully vdescribed and particularly pointed out in the claims.
The annexed drawing and the following description set' forth inl detail a.- certain structure embodying theinvention, such disclosed means constituting, however, but several of various structural' for-ms in which fthe principle of the invention 'may be used.
In said r'annexed drawing Fig. l is a top plan view of our'inven- Vtiony as embodied in lthe stove type burner; Fig. 2 is a? longitudinal sectional relevation taken centrally of the yview shown in Fig. l;
.or passageway, asis clearlyfshown in Figs. l
Application iled July 13, 1923. Serial No.A 651,237.
Figi` 3 is a detailview takenv along the line 3-3 shown inqFig. l, looking in the direction of the arrows; Figs. 4, 5 and 6 are transverse sectional views taken `along the lines if-4, 5-5 and 6-6 shown in/Fig.' l; Fig-7 vis a-fraginentary viewy showinga modifiedform of the gas passagewayoffthe burner, and@ Fig. 8Y is aside elevationof the conventional Bunsen burner as modiedvto include certain features "of the invention.
; Asis clearly shownin Figs. land 2,'the
gasburnerwhen ofthetype utilized on domestic glas-f stoves, is` preferably vmade as an integral casting embodying a jet or'nonzle ,sect-ioni, agas mixturey chamber 2,5 and an airzval-ve portion .3. The jetL or nozzle sec'- tion of the burner comprises an annular base portion 4: anda loosel top plate 5, which pro'- vide at their meeting edges a pluralit Iof orifices, as4 .will be hereinafter described.
The gas mixture chamberor passageway 2, `conveys to the vjet portion of the burner the `combusti-ble mix/ture of gas and air received in the usualmanner from the valve portion 3=of the burner, which is of theconventional form -found-.in gas 'stoves for domestic `use andils 4ofconmal shape and providedvon its rearwardvface'with' a pair of valveplates (i` having a central opening (notfshown) for `afjet from thefsourceA of gas supply4 and a plurality of registering" openings arranged 4aboutmthe samef and adaptedftobe secured '1n adjust-ment withj any; desired degree f of opening by means of a set screw 71. lt has :been found that these openings maybe made very Alarge because of the` efficiency of the withstanding` lsuchV 'enlargedl openings the flame does not snap back.
The body of thegas and air mixture chamber 2, 5.and 6is ofy irregular configuration, ythe interior thereofpresenting a `series of inclined. wallsl alternately disposed at different anglesatrspaced intervals inthe length of saidpassageway. In the form illustrated .the circumferential size of the tube is not changed, butits cross-sectional shape is varied- 4throughout its length.` Thus, asis showin in Fig; 4, 'at a point adjacent the valve end of the device, the gas mixture passagevvayy presents a circular crossesection, Whileat a pointsomewhat nearer" the jet portion 'of the devicethe gas mixture II'Jassageway presents an kelliptical cross-section,
as is. shown in Fig. 5, having its larger vdvburner andr it `has alsoi beeni found vthat not- CTI ameter in a vertical direction, while at a point still somewhat closer to the jet portion of the device the gas mixture passageway presents an elliptical cross-section having its larger diameter in a horizontal direction, as is shown in Fig. 6. rlhu-s, as the mixture of the air and gas passes from the valve end of the device to the jet portion thereof, it will be thoroughly intermixed through the cross currents set up by the irregular conformation of the interior wall of said passageway.
The particular shape of the gas and air mixture chamber may be greatly varied according to the uses to whichtlie burner is to be put. 1n the form of device shown in Fig. 7, depressions 8in t-he gas mixture passageway are formed longitudinally instead of transversely of said tube and are placed at different radial angles alternately so as to provide an irregular inner wall forv said passageway. Y
The jet portion of the burner comprises, as has been indicated, an annular base portion 4, and a loose top plate 5. rlhe annular base portion has an upstanding central flange 11,- which is joined with a circumferential flange 12 by means of an integral bottom plate 13. Said bottom plate is depressed at the point where it merges with the laterally extending gas and air mixture chamber or passageway and thus provides a shallow chamber within the nozzle portion of the burner when the top plate is in position.
The central flange 11 is preferably in the form of an upwardly tapered truncatedcone and, as shown in Fig. l, is formed in octahedral shape, the sides being formed in a series of short arcs facing outwardly from the center of the device the edge thus presenting a serrated or scalloped appearance. The circumferential flange 12 is preferably inclined outwardly and upwardly and likewise has a serrated or scalloped appearance, the edge presenting a series of short arcs facing 1nwardly with respect to the center of the device.
The top plate 5 of the jet portion of the burner comprises an annular member having a shallow central flange 14 and a circumferential fiange 15. The circumferential portion of the plate is inclined upwardly and outwardly and presents a serrated or scalloped outer circumferential edge formed of a series of short arcsfacing outwardly from the center of the device. The central aperture of the top plate has an inwardly and upwardly inclined wall presenting a serrated or scalloped edge formed of a series of short arcs facing inwardly toward the center of the device. As is clearly shown in Fig. 1, when the top plate is seated about the upstanding central flange of the base the marginal arc-shaped portions of the top plate will engage with the similarly shaped portions of the base, the points of juncture of the several series of arcs on the top plate being interposed between similar points in the arcshaped portions of the flanges of the base member. Thus, as is clearly shown in F ig. 2, the marginal surfaces of the top plate will be in close contact with the flanges of the base aty the points where said arcs join in said top plate and base, respectively. Between such pointsof contact, as is clearly shown in F ig. 3 of the drawing, the top plat-e and marginal flanges will be spaced from each other providing a series of lenticular gas orifices 21 about the inner and outer circumference ofthe annular jet portion of the burner.
rl`hrough the construction just described there is produced a thorough mixture of the air and gas as it passes the inclined surfaces on theinterior of the gas mixture passageway, anda still further mixture as it emerges rfrom the lenticular angularly dis,- posed orifices of the jet portion of the burner. The thorough combustion of the gas andrair mixture is furtherassisted by the fact that the individual upstanding arcshaped flanges forming the orifices of the jet portion of the burner have beveled outer sides 21, 22, 23, 24C, respectively, and that at the meeting points of said respective arcshaped sections there are formed vertical grooves which serve as channels through which the surrounding air is drawn during the process of combustion. This Vinfiuences the height and shapel of the cones of flame over the separate orifices and improves the action of the burner. V
In order to support the burner in the usual manner upona gas stove, an integral stud 16 may be secured to the under side of the jet portion of the burner at a point opposite the enlargement at one side thereof. Similar, supports may be provided where desired. f
It is to be understood that while the body of the burner apart from the top plate has been described as a single kintegral casting, it is not intended to limit the invention to `such particular construction and it is contemplated that the burner may be made in separate parts and assembled, or that if desired, the gas and air mixture chamber may be of metal tubing having its sides indented to provide the interiorly inclined walls.
Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
We therefore particularly point out and distinctly claim as our invention 1. A gas burner comprising ya tubular gas passageway, a valved intake member at one end thereof and a jet member at the opposite end thereof, said jet member being angularly disposed with respect to said tubular gas passageway, an an inner and outer series of lenticular orifices formed in said jet member, eaclralternate orifice being angularly disposed with respect to its immediately adjacent orifices.
2. A gas burner comprising a tubular gas passageway, a valved intake member at one end thereof and a jet member having an annular base portion provided with inner and outer anges in the form of a series of small arcs, the concave portions of the arcs ofthe respective ianges facing toward each other, 15
and an annular top plate having inner and outer edges shaped in the form of a series of small arcs having their concave portions facing outwardly, said arceshaped parts of said @seV and top plate respectively intertting 20 BERNARD A. GEURINK. LOUIS H. GEURINK.
