STOVE CONSTRUCTION Filed Sept. 17, 1934 Patented Dec. 1, 1936 UNITED STATES STOVE CONSTRUCTION Anton J. Yeager, Wisconsin Rapids, Wis., assignor to Prentiss Wabers Products 00., Wisconsin Rapids, Wis., a corporation of Wisconsin Application September 17, 1934, Serial No. 744,317

1 Claim.

This invention relates to a new and improved stove construction, and more particularly to a construction including a plurality of burner sections with a single control for such sections. My invention is particularly adapted for use in connection with gasoline vapor stoves, although it is applicable to stoves using other types of gaseous fuels.

It is customary in stove construction to have a plurality of burners of differing sizes and in some cases a plurality of such burners are adjacently placed so that they may be jointly used under a single utensil.

It is an object of the present invention to provide an improved stove construction comprising a joint control for a plurality of burner sections.

It is a further object to provide a construction in which a single rotary valve controls a plurality of adjacent fuel passages.

It is an additional object to provide a construction in which the control means is a disc valve operating against a substantially fiat surface.

It is also an object to provide a construction in which the valve disc is yieldingly held against the flat surface.

Other and further objects will appear as the description proceeds. I have shown a preferred form of construction of my improved device in the drawing accompanying this application, in which Figure 1 is a fragmentary elevation, partly in section, showing a burner and manifold assemly;

Figure 2 is a plan view of the construction of Figure 1 with the burner sections removed;

Figure 3 is a fragmentary View showing the valve disc and associated passages with both passages closed;

Figure 4 is a view similar to Figure 3, with the left passage open;

Figure 5 is a view similar to Figure 3 with both passages open; and

Figure 6 is a View similar to Figure 3 with the right passage open.

In the drawing, as shown in Figures 1 and 2, the fuel manifold H has the burner supporting member l2 secured thereto by bolts I3. The fuel passages l4 and extend through the member l2 and open on the substantially flat face l6 of the member [2, as shown in Figures 3 to 6. When assembled to the manifold H, the wall [6 is located in the side of the manifold passage.

The smaller or simmer burner member I! is carried upon the portion of the member I2 which houses the passage M. The ring burner I8 is carried on the portion of the member l2 which houses passage l5 and also rests on lip 19 formed on the lower portion of member H.

The valve disc 26 is secured to the end 2| of the valve stem 22. The coil spring 23 is carried on the valve stem 22 between the washers 24 and 25. The washer 25 engages the member I2 while the Washer 24 is held in place by the cotter pin 26. The actuating handle 21 is held in place on the end of the valve stem 22 by means of the set screw 28.

The valve disc is provided with an elongated cut away portion 29 and a smaller cut away portion 30. The function of these cut away portions is clearly shown in Figures 3 to 6 inclusive. In Figure 3 the solid portion of the valve disc covers both passages I4 and I5 and this is the normal valve position with both burners off. A rotation of the valve disc to the position of Figure 4 opens the passage 14 to supply fuel to the simmer burner IT. A further rotation to the position of Figure 5 serves to uncover the passage l5 while maintaining the passage 14 also open so that both burner sections I1 and 18 are supplied with fuel. With the valve rotation continued to the position of Figure 6, the passage I4 is closed while passage I5 is briefly closed and then reopened. In this position the simmer burner I1 is off and the main burner section [8 is supplied with fuel.

It will be understood that the burner sections are preferably located sufficiently close together so that one section will be lit from the other. Hence when either section is once lighted any desired change may be made by rotation of the handle 21 without necessity for further lighting of the burner. While the passage I5 is momentarily closed off in moving the valve disc from the position of Figure 5 to the position of Figure 6, this will not put out the burner, as sufficient gaseous fuel will be in the passage I5 and burner cavity to maintain the burner section lighted for this brief period. The spring 23 serves to urge the valve disc against its seat, and the pressure of the fuel in the manifold acts in the same direction. The disc therefore, serves to effectively seal off the passages to the burner sections when closed, and yet may be easily turned to give any desired burner combination for use, and, once lighted, the burner combination may be instantly changed as desired.

It will be understood that the particular form of construction shown is only a single example of apparatus for carrying out my invention and that a valve disc located against said wall, said valve disc serving by rotation to selectively open and close said passages, a rotatable valve stem secured to the valve disc and supported in and extending through the connecting member, spring means carried by the valve stem externally of the connecting member and bearing against said member to maintain the valve disc against the inner wall of said member, and actuating means secured to the outer'portion of said valve stem, the connecting member and valve mechanism being removable from the manifold as a unit.
