BURNER STRUCTURE Filed July 24', 1939 in LfBS I NV EN TOR.

CLARENCE A.HERMAN ATTORNEYS Patented Mar. 18, 1941 UNITED" STATES PATENT OFFICE BURNER STRUCTURE Clarence A. Herman, Grosse Pointe Farms, Mich, assignor to Detroit-Michigan Stove Company, Detroit, Mich., a corporation of Michigan Application July 24, 1939, Serial No. 286,256

Claims.

ignited gas from flashing or working back into the head and mixing chamber of the burner, there maybe serious consequences, and if the over-all number of such ports is not sufllcient-to provide the proper flame, the burner is inemcient. Ordinarily it is quite difflcult and expensive to drill the required number 0! ports of the proper size, therefore I have designed a burner structure to overcome such difliculties.

One of the essential objects of the present invention is to provide a burner wherein the gas ports are formed by superposed stampings and the like that can be accurately made and assembled to produce the desired results.

Another object is to provide a burner structure that is easier and less expensive to make than the drilled type of burner mentioned above.

Another object is to provide a burner wherein the over-all number of ports may be increased or decreased according to the number of superposed parts employed.

Another object is to provide a burner wherein the gas entrance end of each port is smaller than the exit end thereof so that the flow of gas through the port will be such as to cause the ignited gas to burn close to the exit end of each port instead of being blown away or outwardly therefrom.

Another object is to provide a burner wherein it is possible for more primary air to be used in the mixing tube of the burner so that less secondary air is required at the 'exit'end of each gas port to provide the proper combustion.

Another object is toprovide a burner structure that is easier to clean and service and wherein replacement of parts may be readily and accurately accomplished whenever desired.

Another object is to provide a burner wherein the top part of the superposed members mentioned may be of suflicient area to serve as a cooking plate.

Another object is to provide a burner with such a. cooking plate that effectively conceals and c5 prevents the time from being extinguished by spilling foods, and prevents the letter from entering or clogging the gas ports of the burner.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:

Figure 1 is a side elevation, withparts broken away and in section. of a burner structure embodying my invention;

Figure 2 is a fragmentary top plan view of the from the head thereof:

Figure 3 is a detail plan view of the uppermost part of said superposed members;

Figure 4 is a detail plan view of one of the corrugated parts of said superposed members;

Figure 5 is a detail plan view of one of the intermediate parts of said superposed members;

- Figure 6 is an enlarged fragmentary plan view of one of the corrugated parts;

Figure 7 is a sectional view taken on the line 1-1 of Figure 6;

Figure 8 is a plan view of the assembled superposed members fanned out for cleaning purposes;

Figure 9 is a fragmentary vertical sectional view through a slight modification.

Referring now to the drawing, A is the mixing chamber, and B is the head of a gas burner embodying my invention.

As shown, the head B and mixing chambenA are integral and are preferably formed as a single casting. As usual, the mixing chamber A is tubular in form and is provided at its free end with an enlarged mouth portion 10 provided with a gas supply pipe II and a shutter I2 by means of which the amount of primary air passing into the chamber A may be readily controlled. I

The head B is likewise tubular in form and extends substantially vertically from the mixing chamber A. The upper end of this head is open and carries a. number of superposed stampings,

which provide the ports for gas. As shown, the stampings C and D, respectively, are identical in construction. Each comprises a ring I3 having radially extending corrugations i4 and having a diametrically extending attaching bar IS. The stamping E intermediate the stamping s C and D is a plain flat ring l6 having a diametrically-extending attaching bar 11. The uppermost stamping F is a flat disk. In Figures 1 to 8, inclusive, the area of each stamping C, D, E and F is the same and is substantially equal to the outside area of the open upper end of the head B. As shown,

the stamping D'is lowermost and has its corrugaf burner with the superposed members removedtions l4 resting on the upper end l8 of the head The stamping E rests upon the corrugations H of the stamping D. The corrugations H of the stamping C rest on the stamping E, and the flat disk F rests upon the corrugations i 4 of the stamping C. Thus, four sets I9, 20, 2| and 22, respectively, of ports for gas are formed by the superposed parts illustrated, the lowermost set l9 being formed by the corrugations ll of the stamping D and the upper end I! of the head, the set 20 by the corrugations ll of the stamping D and the stamping E, the set 2| by the stamping E and the corrugations H of the stamping C, and the set 22 by the corrugations ll of the stamping C and the disk F.

By varying the number of stampings in the assembly, the over-all number of sets of ports may be varied accordingly. For example, if only two sets of ports are, desired, the stampings C and E would be dispensed with so that the disk F could rest upon the corrugations H of the stamping D. If six or more sets are desired, additional stampings such as C and E are interposed between the disk F and the upper stamping C. i

In the present instance, each set of ports is substantially the same in contour and cross section and each port has an entrance end which receives gas from the interior of the head B and has an exit end 3| where gas is discharged to be ignited. Actually the entrance end 30 of each port is smaller than the exit end 3| thereof, and the side walls 32 and 33 of each of said ports are gradually flared from the entrance end 30 to the exit end 3| so that the how of gas through each port will be such as to cause the ignited gas 7 to burn close tothe exit end 3| of each port instead of being blown away or outwardly therefrom. The cross sectional area of each port is such as to preclude the ignited gas flashing or working back into the head B, yet the over-all number of such ports is such that a proper flame is assured. .Especially is this so when both the number of sets of ports and the shutter 12 for primary air can be so easily controlled. In fact, my construction is such that more primary and less secondary air may be used to provide the proper combustion.

For anchoring the stampings in place relative to the head, I have provided a crossbar 40 within and fixed to the head adjacent the upper end thereof and a screw II that engages aligned openings 42, 43, 44 and 45, respectively, in the stamplngs and threadedly engages the crossbar 40.

To permit the parts to be cleaned while maintaining their assembled relation, I have provided a hollow rivet 45 that extends through aligned openings 41, 48, 49 and 50, respectively, in the stampings and swivelly connects the same together. Thus, when it is desired to clean the structure, the screw 4! is removediiomthecrosm bar 40 and stampings C, D, E and F so that the latter as a sub-assembly may be bodily removed from the head The individual stampings may then be swung around the hollow rivet 46 as illustrated in Figure8 so that they will be accessible for cleaning purposes.

In Figure 9 I have illustrated a slight modification'in which the top part F of the superposed members is of suflicient area to serve as a cooking plate. As shown, this plate F is thicker and larger in diameter than the disk F and extends over and beyond the burner opening 60 in the top frame H of the gas range. The plate F be a casting and is anchored by a screw H to may the crossbar 40 of the burner. To permit the products of combustion to escape from under the plate F, there are a plurality of legs 63 on the underside of the plate F and resting on the top frame SI of the range. Thus, these legs 63 space the plate F a suflicient distance above the top frame 6| to provide vents $4 for the products of combustion and transmit the load from-the plate F to the top frame 6| instead of to the burner head B. i
