Fig. 12 is a sectional view as taken along the line XII--XII in Figure 4, and looking in the direction of the arrows. Figl-13 is fa plan Y view of the burner base plate and of the burning ports and by making them as 15' narrow as shop practice ’would permit.A However, the deep narrow ports occasion considerablere sistance to the flow of gas and it is thereforede sirable to make the sides of the ports smooth and free from rough projections. 'The narrow slotted 20 ports, however, prevent the flame from travel ing back down through them, which sets up a definite resistance to ñashback. The additional depth of the burning ports by increasing the area of metallic surface contacted 25 by the air-gas mixture during its flow from the orifice to the burning edge, presented the possi bility of heating the air gas mixture to such an extent that excessive pressures would result with in the burner box. I overcome this tendency by 30 cooling the burner head, this is done by bringing the secondary air for combustion up between the ports; this feature also furnishes a further ad vantage in that it gives a desirable distribution of such secondary air throughout the entire ñre. To recapitulate; my improved gas burner in 35 cludes an increased area of cooling surface on the Venturi ~`tube integral therewith. VSimilar nu merals» of ' reference designate the same pa'yrt throughout the several figures of the drawing. Referrlng'fto the drawing, Yat Ill are the base 20 casting walls, integral with an intermediate cast T-pipe fitting II provided with a jet I2. A rec tangular shaped upper portion I3 is also integral with the side walls I0 and at the four corners thereof may be seen corner elements I4 and a 25 raised triangular portion I 5. Upon the base seen in Fig. 8 and just described, I next assemble the element seen in Fig. 7 which has a base member I6 as a plate supported by the four corner ele ments I5. Integral with the member I6 is a 30 Venturi tube I'I extending a little below the base I6 as at I'Iœ and upwardly the height desired as seen in Figs. 9, 11, and 12. This Venturi tube may be surrounded by the wall element I8 as shown Figures 1, 2, and 11 in which case a slotted 35 projection I9 would occur at the upper part of from a study of the drawing and as amplified the end walls for purposes later explained. I next assemble an inner box-like element 20, open at its lower end and surrounding the Venturi tube I'I as disclosed in Figs. 6, 9, 11, and 12. The lower 40 end of the element 20 is provided with a pair of centrally disposed extensions 2| and a pair of centrally disposed extensions 22, thus providing through the description thereof which follows. ports 23 and 24 at the lower side and end walls burner head for the purpose of reducing the heat ing effect at these points; next, the increased depth of port overcomes flashback under variable 40 conditions; and finally, I provide a wide and im proved secondary air distribution to the' fire. These and other advantages will be apparent Fig. 1 is an end view of a single burner; it being understood my burner may be employed in mul tiple units if so desired. Fig. 2 is a side elevation of the burner shown in Fig. 1; a portion of the figure is broken away for purposes of description. 50 Fig. 3 is a plan view of the burner. Fig. 4 is an end view of a modified form of the burner. Fig. 5 is aside elevation of the burner shown in Fig. 4. Fig. 6 is a top view of the elements seen in Fig. 2 with the burner port section disclosed in Fig. 3 45 55 removed from the assemblage. Similarly Fig. 7 of the element through which the air-gas mixture, 45 admitted through the jet I2, tube I'I and passage 25, will pass into the passage 26 intermediate the element 20 and the outer side walls I8. It will be noted that the upper end of the element 20 is closed by an inverted V-shaped roof portion 50 as seen at 21. The assemblage shown in Figures 1 and '7 just described is now ready to receive the burner ele ment seen in Fig. 3. As will be noted in Figs. 4, 5, and 12, this element may have a depending 55 2 2,057,216 box like side wall section cast integral with the burner section as at |83: with slotted projections such as |91: adapted to register with the slotted My burner by eliminating flashback also elim projection 163:, Fig. 13, and be clamped by the bolt inates noise and ñre hazards and other dangers. The invention in general is for similar purposes to that of my pending application for Gas bur means 28. ners, Serial No. 693,128. Or the burner element may ñt as seen in Figs. 1, 2, 9, 10, and 11 upon the upper part of the Wall element I8 and slotted projections I9’ register withV the projections I9 for bolt clamping purposes; the passage 26 leading to the burner 10 ports being the same in either application. If Ydesired a gasket maybe employed as seen at 29 . Such modiñcations may be employed as lie within the scope of the appended claims. Hav ing fully described my invention, what I now claim as new and desire to secure by Letters Pat ent is;_„ _. „ Y 10 . V1.

The `effect of having an inverted V-shaped top portion andgas the pitch given at 33 is shown in Figures 9, 10,` 11, v ports adjacent said plate, a flat top gas burner 20 and 12 as a top section arranged above the roof element arranged above the top- portion of the - element 21 previously> described, and for a con tinuation of the gas passage 26 as seen at 26:1: ad rnitting the air gas mixture to the gas ports as 25 later described. It will be noted in the several figures that the effect of the conventional Venturi tube seen at l1 is continued throughout the pas sage 25, the pasasge 26 and 26x, the ~wall elements being so fashioned or cast as to give this charac 30 teristic. Deep narrow slots'34 provide the gas ports. A plurality of burner sections suchas 35 are seen in Figures 2, 3, 5„ 11, and 12 cast integral with the part 33 as disclosed in Fig.f11, in each Yof the sections 35 is disclosed >the/deep narrow 35 slotted orifices 34. Wide air passages for secon dary air therefore occur from the side 36 to the side 3lY as clearly shown in Figs. 2 and 9. The effect of this secondary air upon theflame at the burner tip 30 is very pronounced both for cooling the members 35 as well as foi` improving the sec ondaryV air distribution.
