9 Claims. I

This invention relates to gas burners formed from two similar, or substantially similar, sheet metal parts. More particularly, the invention deals with burners, wherein the chamber or casing portion of the burner terminates in an outwardly extending peripheral flange, the flange being corrugated angularly to the edge of the flange so as to form, on the resulting burner, angular discharge nozzles. Still more particularly, the invention deals with burners of the character described, wherein the arrangement of one burner part on top of the companion burner part, in securing said parts together, will dispose adjacent discharge nozzles in different angular relationship to each other.

The novel feature of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a plan view of a part of one form of burner which I employ with part of the construction broken away in illustrating opposed angular relationship of the discharge nozzles of the burner.

Fig. 2 is an enlarged section on the line 22 of Fig. 1.

Fig. 3 is an enlarged detail view, looking in the direction of the arrow 3 of Fig. 1.

Fig. 4 is a diagrammatic plan view of a modifled form of burner which I employ with part of the construction broken away.

Fig. 5 is a plan view of another form of burner with part of the construction broken away; and

Fig. 6 is a plan view of another form of burner which I employ, with part of the construction broken away.

In gas burners of various types and kinds, it has been customary to provide a cast burner with a series of discharge ports, or nozzles, spaced along peripheral edge portions thereof, or to form discharge nozzles between two sheet metal parts, usually of difierent construction, wherein the discharge nozzles are disposed at right angles to the peripheral edge of the burner.

The purpose of my invention is to provide a burner of the character described, which is formed from two similar sheet metal stampings and, in some cases, one of the stampings is modified solely for the attachment of the gas supply tube but, more particularly, my invention deals with the arrangement of the discharge nozzle passages on the flanges of the burner parts, so

as to be disposed angularly thereon. Thus, in arranging two similar burner parts one upon the other and securing the same together, discharge nozzles disposed angularly to each other will be arranged along the peripheral edge of the burner, so that adjacent flames will extend angularly to each other and, at the same time, be sub-divided to, at least, a slight extent to insure complete ignition of all of the nozzles and produce a continuous flame throughout the periphery of the burner.

In Figs. 1 to 3, inclusive, I have shown one adaptation of my invention, wherein the burner I0 is in the form of an elongated central tubular body I I, having an admission end it for introduction of the gas and a rounded closed end [3. Along the sides of the body II are laterally directed and opposed tubular extensions l4, having rounded ends, as at IS. The extensions 14 join the body H in rounded wall portions, as at IS. The complete burner is formed from two similar sheet metal parts ll, ll, these parts having peripheral flanges l8, l8 and the flanges are corrugated angularly to the edges of the flanges, particularly on the straight wall portions of the extensions M, as illustrated in Fig. 1 of the drawing and shown in detail in Fig. 3. The corrugations form offset walls l9, 19 which, in conjunction with opposed abutting walls, 29', 20 form the gas discharge nozzles or

passages

21, 2|. The portions of the

walls

20, 20 which overlap between the nozzles Zl, 2| can be welded or otherwise secured together. At the outer edges of the flanges, these walls abut, as indicated at 22 in Fig. 3 to subdivide adjacent nozzles 2|, 2| one from the other.

By an angular arrangement of the corrugations in the manner diagrammatically indicated in Fig. 1 of the drawing, the reversing of the two similar parts ll, ll one upon the other will reverse the angularity of the nozzles. In other words, in one part, all of the flames will be directed in one common direction as, for example, the direction of the full line arrow 23 of Fig. 1; whereas in the other part, the flame will be directed in the direction of the dotted arrow 24 of said figure. Where the corrugations extend through the rounded portions of the flanges, a somewhat wider spacing between the discharge nozzles will prevail but these discharges will be sufficiently close to facilitate complete ignition of the burner from any one position by extension of the flame in ribbon-like fashion around the flanges.

In this connection, it will be understood that the particular size and angularity of the corrugations forming the resulting nozzles 2!, 21' can be varied, depending upon the size and dimensions of the burner and the illustration in the accompanying drawing is simply a diagrammatic illustration.

In Fig. 4 of the drawing, I have diagrammatically shown a slight modification of the structure shown in Fig. 1 which would amount to a section of the burner shown in Fig. 1, including two of the extensions l4 and dispensing with the ends l2 and I3. In other words, a substantially H-type burner 25 is employed, wherein the two

parts

26, 26 are identical, except from the standpoint that the part 26 is apertured, as seen at 21, for the reception of a fuel admission pipe for introducing gas into the burner.

In Fig. 4, the tubular extensions 23 are substantially identical with the extensions [4 of Fig. 1 and these tubular extensions are united in a central tubular portion 29. The peripheral flanges 30 will be corrugated, as with the structure shown in Fig. 1, to produce the distribution of nozzles, the same as in Fig. l. The type of burner, shown in Fig. 4, is suitable for use in small ranges, or two of such burners could be used in a range; Whereas, with the structure shown in Fig. 1, a single burner can be utilized to heat the range compartment of a gas stove.

In Fig. 5 of the drawing, I have shown a modified form of burner which is in the form of a single elongated tubular body 3|, having an ad mission end 32 and a closed end 33, the body having, throughout the major portion of its length, a peripheral flange 34. burner is formed from two similar parts 35, 35', having the flanges corrugated angularly to provide the

nozzle discharges

36, 36. Again, as with the construction shown in the other figures, the formation of a single sheet metal stamping is utilized to produce the resulting burner. It is preferred that the sheet metal employed be of a type and kind that will withstand the tempera.- ture and such material as stainless steel is suitable for this purpose.

In Fig. 6 of the drawing, I have shown my invention as applied to the construction of a round ring-type burner, such as generally used on the top of gas stoves for the heating of pots and pans in the preparation of food. Here again,

the burner is formed from two similar sheet metal parts 31, 31', the part 3'! being modified only to the extent of having an aperture 38 therein for reception of a gas supply pipe.

The burner shown in Fig. 6 has a ring-type tubular casing 39, having an inwardly extending flange portion 4!], 4B and an outwardly extending flange portion 4 l, 4 I These flange portions are corrugated to form the discharge nozzles 42, d2 angularly disposed to each other, as with the construction shown in the other figures. The only difierence in Fig. 6 of the drawing is that, instead of simply placing one sheet metal stamping directly upon the top of the other to form the resulting burner, the one stamping is rotated to a slight extent in this inversion, as will clearly appear from a consideration. of Fig. 6, the purpose here being to provide a distribution of the nozzles through the entire periphery of the burner so as to distribute the flame and to insure complete ignition of the entire flame in carrying from one nozzle to the other. Here again, it will be understood that the illustration in Fig. 6 is diagrammatic in illustrating an adaptation of the invention and the size of the Here again, the

corrugations and angularly thereof can be varied to produce the most desirable results in the finished burner.

Considering Fig. 1 of the drawing, it will be apparent that sufilcient spacing is provided between the extensions 14 to facilitate eflicient operation of the burner and this spacing also will be practical from a standpoint of producing the sheet metal stampings with a minimum of waste by the possibility of nesting the projections or extensions [4 of one sheet with respect to those of an adjacent sheet.
