GAS BURNER.
Appnoatmnmea April 2, .1926.e serial no. 99,213.
M invention relates to an improvement in .gas urners, and my object is to providea| burner in which a commingling tube is ada ted to jet a mixed stream of air and as atuhigh velocity against a baiiie member whlch is preferably a separate element sleeved on v the tube, whereby va vsupplemental mixing .such
- a llame under normally high .gas pressure' i'efect is obtained and a spreading sheet of -fiame maintained oppositethe mouth of ,the tube. The gas orifice in the tube is so small that it causes a fine stream ofgas to jet through the open mouth ofthe tube with orce that it is impossible to maintain o rations unless the ilow of gas is checked a er it issues from` the mouth of the tube. The baille member which I mount upon the commingling tube not only checks the gas stream but also serves to effect a more intimate mix of the gasand air which passes .through the tube, it being understood that the air which is drawn into the commnglingtubeis notvsuicie'nt in itself tomaintain a flame at themouth of the tube exceptin at such times as the gas pressure' is reduce or notl sufficient to'jet the gas against the baille mixer with spreading and intermixing effect.
separate baille member sleeved` rotatably on the commingling tube rmits variable settings to be made where y the flame may be caused to spread in different directions relatively to the mouth of the tube, and where A a. plural number of such devices Vare grouped together the llames may be either concentered kor diiused to lay on smaller or larger heating surfaces. hese desirable results are further fostered by grouping a plural num ber ofsuch devices on angularly relatedflines ;-,on,line 4 4 of Fig. 2. Fig. 5 is a cross-sec-v A tignof the hub or sleeveportion ofthe. baille ixiember, showing that it may bemade hex- 'substantially as herein shown and described` and as delineated in the accompanying draw-3 ings, in which Fig. 1 is a sectional view of a burner embodying my invention, andFig. 2 is assectional view .of a part of the same burner showing the baille mixer rotated or turned to deflect the-dames downwardly and outwardly. Fig. 3 is a cross-section of the baille memberon line 3-3 of Fig.'2, and Fig. 4 is a sectional view of the same element agonal instead of round, if preferred.' Fig.
6 is a top view, on a reduced scale, of a burner such as delineated in Fig. `1, the arrows 1ndicating in a general way the circumscribed -the direction and spread of the flames from each mixing unit. Fig. 8 is 'a side view, partly in section, of a modified form ofburner having two mixing unitsarranged back to back in upri ht position, and Fig. 9 is al'top tiew of anot er modified form of burner in which three mixing units -are grouped to` gether. Y
The'burner comprises a gas distributing body or-manifold 2 of any suitable shape,
Iupon which any desired number, of relatively small commingling tubes 3 may be mounted. As shown in Figs. 1 to I, body 2 is a hollow ring with a, flat inclined wall 4 annularly Y at itstopinto which a series of brass tubes 3 are screwedat uniformly spaced intervals z radially of the ring. These tubes inclineout- Wardly and uupwardly and are divergingly related, and a small gas orifice 5, located axially -within the base end of the tube, per-l mits. a fine stream of pure gas, either natural or artilicial, to be pxrojected into and through I a larger bore or amber 6 within the tube. One or more lateral openings 7 in the hexag# .onal enlargement or lower end 8 of the tube permits a small amount vof air to be entrained y the stream of as issuing from orifice 5, a d the air intake and the mouth oforice 5 are preferably closely related tomore eectively entrain the air. The diameter of the tube and the length thereof are such that the fine stream of gas is jetted, undernormal operating conditions, not only through the tube'but also some distance beyond the mouth thereof, and although air 1s entrained with the gas the mixture is not sufficiently complete to 'eifect rfect combustion and constant burnin ereof at the rapid rate of speed at which 1t issues. How'- ever, upon reduc'v the pressure by valve or otherwise a small ame-can be maintained at the mouth of the tube without backfire. But upon incre the pressure and jetting the as in increase volume through the tube the' ame .will be blown out unless a back res'- sure is .established at some distance om the mouth of the tube.. A more intimate ioo mixture with the` air is also required to prov ditional air vmixture by attaching a spoonshaped element 9 directly to the tube; preferably by means of a round or hexagonalA hub portion 10 having a longitudinal bore adapted to sleeveover the round part of the tube in rest vposition against its enlar ement v8.- Element 9 comprises a concaved ranch 11 of lflaring shape cast integral with hub 10 and extending from one side thereof on substantially parallel lines with the axis of the tube, although the concaved recess or cavity in the innerface of the branch may diverge slightly on inclined linesv relatively to such axis unt-il merged with a similar concaved surface lof a curved lip or liange 12 Which'v is bent a`t substantially right angles and forms a shallow cup or ocket directly opposite the mouth of the tu e and some distance therefrom, the distance or space between the cup and the mouth of tube 3 being approxivmately the same as the length of the tube.
Thus thel gas stream whichpasses through the tube is projected approximately the same distance beyond the mouth `of the tube before striking the curved concaved surface of the flan e or cup 12. The gas str eaml is thereby di used within the open cup or pocket and a cushioning bod of gas and air con-v stantly maintained in a vance of the stream or jet, whereby a more intimate andthorough mixture of gas and air is effected and a spreading sheet of blue flame obtained. This dame naturally rises to a higher elevation but may be directed either toward the center of theburner body, or in the opposite direction and to a greater distance from the center, by rotatingl the element upon the tube so as to project the flange or cup 12 either upwardly or downwardl as delineated in Figs. 1 and 2. In Fig. 6 a of the baie elements are turned up whichconfines the I iiame within a small circumscribed area,
whereas .in Fig. 7the elements are turned alternately up and down to show the greater spread of ame where the elements are turned down.
In Fig. 8 I show a modified form of the invention, a relatively small {lat-sided head 14` I In Fig. 9 I show a top view of a small gas distributing head or manifold 16 of. clover leaf shape having three upright tubes and auxiliar mixers and spreaders therefor arranged ack to back to direct the separate sheets of flame in three directions. Other modifications of the same nature may be made and still fall within my concept 'and scope ofthe invention.
What I claim', is: f
v A gas burner, comprising a hollow as distributing body, av series of short tu es eX- tending upwardly from said body, a baiile member spaced apart from the mouth of each tube approximately the same distance as the length of the tube, and each tube having. an
axial gas vorifice of small diameter Vadapted to jet a stream of gas at high velocity a substantial distance beyond the mouthof the v tubeunder normal gas pressures, and each tube also having intake ports of restricted area to permit a limited amount of air to be entrained by the gas 'stream without causing combustionwithin the tube itself under the bafck pressure established by said baille member.-
ture.
