Description

I April 9,1940.
0. A. NOE 2,196,339
STOVE Filed Aug. 15, 1938 2 Sheets-Sheet 2 Patented Apr. 9, 1940 UNITED STATES AVTENT oFFrcE I 3 Claims.
This invention relates generally to stoves. More specifically, it relates to an improved stove top for use with gas and other fluid fuel burning stoves.
In the conventional type of fluid fuel burning stoves, a number of separate burners are arranged in spaced relationshipwith each other and are covered with an open grill, the sole purpose of which is to supportthe cooking vessels.
9" It is well recognized that this type of stove is face, is relatively thick at its center and is relavery inefficient when considered from the point of view of the quantity of heat which is actually utilized as compared withthe amount of heat which should be'useful-ly available per unit of fuel consumed. Also with the conventional type of stove, it is not feasible totu'se more cooking vessels than the number of available burners in the stove. A further objection to the use of a grille to support cooking vessels is that this grill is difiicult to clean and, therefore, due to the spilling of foods, frequently becomes greasy and unsanitary.
'It is the primary object of my invention to provide a stove top which gives greatly increased cooking emciency per unit of fuel consumed.
Another object of my invention is to provide a stove top which will support'a greater number of cooking vessels than is possible with the conventional type of stove, and with which all of the cooking vessels will be heated by a single burner. 1 F 1 l Anotherobject of'my invention is to provide a stove top which will provide an evendistribution of heat to large cooking vessels or to a num-' ber of cooking vessels.
Another objectofmy invention is'to provide a stove top which maybe easily cleaned and which will consequently be much more sanitary.
The above enumerated objects and other obvious advantages of my invention are accomplished by providing astove top in the form of a metal sheet which has a'plane upper surface and having its lower surface in the form of an inverted polygonal pyramid.- I prefer to construct my stove top of metal'having a high cone ductivity, such" as aluminum. From the above description, it will be seen that I have provided a stove top which, while having a flat upper surtively thin at its edges due to the uniform tapering of the lower surface. When heat is applied by means of a single burner located at the vertex of the inverted pyramid which forms the lower surface, the stove top will become heated and after the burner has been lighted for a few moments, the stove top will reach a state of equilibrium in which all parts of the upper surface of the stove top are at substantially the same temperature. In this way I am able to provide a stovetop which is heated by means of a single burner and which prevents any part of the stove top from becoming overheated while other parts remain relatively cool. Since the upper surface of the stove top is merely a flat plane, it is easy to clean and thus contributes to cleanliness and sanitation. I 1
A more detailed description of myinvention may be had with reference to the appendeddrawings in which" s Figure l is a perspective .view of the upper surface of a stove top'constructed with my invention; I 1 i 1 Figure 2 is a front'elevational view of my stove top showing the supporting frame and a burner in position; Figure 3 is a cross sectional view taken on the line 3-3 of Figure 1; I
Figure 4 is a plan view of the supporting frame with the stove top removed and the burner. in position;
Figure 5 is a plan view of a stove top constructed in accordance with a modified form of my invention; and I Figure '6 is a cross sectional view taken along the line Gm-G of Figure 5.
In the drawings, wherein like parts are designated by like reference characters in all of the views, the stove top in general is designated by the reference character I; The' reference numeral. 2 designatesthe flat plane upper surface of the stove top, while its edges are designated by the reference character 3. The lower surface of the stove top is in the form of an inverted polygonal pyramid with a vertex 4 at its center and withupwardly-inclined surfaces 5. While. in the form of the invention which I have il1ustrated, the stove top is square, I do not wish my invention to be understood as limited to this shape, since it is obvious that the stove top may be made of any desired polygonal shape, or, if desired, item be. madepcircular in shape and having a lower surface in the form of an inverted cone. The stove top may be supported by a framework designated generally by the reference numeral 6. The framework 6 comprises angle irons I extending around the edges of the stove top and an inner frame of angle irons B'Which are riveted together and connected to the outer frame formed from angle irons I by means of the in accordance diagonally extending braces 9. Depending from the inner supporting frame are the L-shaped burner supports l0. These burner supports are provided at their lower ends with diagonally directed extensions II which are provided at their inner ends with drilled holes 12.
A burner I3 is provided on its lower side with lugs l4 which are spaced to fit into the drilled holes I 2 in the burner support. The burner l3, which is thus supported, may be of any conventional design, but I prefer to use a large polygonal shaped burner which, though of course much smaller, is of the same general shape as the stove top. The shape of this burner is best shown in Fig. 4, where I have illustrated a square gas burner which is provided with combustion apertures 29. At the center of the large burner I prefer to provide a pilot burner [5 which is provided with combustion apertures IS. The pilot burner is supported within the center of the large burner by means of the shelf type brackets ll.
Gaseous fuel is introduced into the large burner by means of the flexible tube It. The introduction of this gas is controlled by means of the valve l9 and the gas is mixed with air within the mixing chamber 20 which is provided with air vents 2|. Gaseous fuel is introduced into the pilot burner by means of the flexible tube 22. The pilot burner I5 is designed to burn continuously.
Since my stove top is Well adapted to be used as a replacement for the conventional grid type top, I have found it advisable to provide my stove top with draft holes 23 to permit ventilation and escape of gases in case the burner is completely enclosed within a conventional type gas stove.
It will thus be seen that I have provided a stove top and burner arrangement which utilizes a single burner to heat a large surface area to substantially equal temperature.
It will also be seen that this is accomplished by the use of a stove top which is ornamental and easy to clean. It will be apparent to those skilled in this art that the use of this stove top will conserve much of the heat which is now lost by the use of the grill type stove top now used on gas stoves.
In the modified form of my invention shown in Figs. 5 and 6, I form a circular hole in the center of the stove top which is designated by the reference character 24. At a point below the upper surface of the stove top, the opening 24 is provided with an internal shelf-like flange 25 and the opening below this flange is of reduced diameter, as shown at 26. This hole is so positioned as to be directly over the pilot burner l5, and is provided with a lid 21 which fits within and is adapted to close the opening 24. The lid 27 is provided with a recess 28 to permit the insertion of a lid lifter to remove the lid. The purpose of this lid and lifter is to permit the insertion of any small utensil into the opening 24 for the purpose of heating it by means of the pilot burner l5. In this manner, it is possible to heat a small utensil without the use of a large burner and without appreciably heating the stove top. The lid 21 should fit snugly into the opening 24 so that when this lid is in place and the large burner in use, there will be a good heat conducting joint between the stove top and the lid 21.
While I prefer to construct my stove top of cast or cold rolled aluminum, it will be obvious that any other material of high heat conductivity will be suitable.
Having thus described my invention, I claim:
1. In a stove assembly, the combination of a stove top comprising a solid metal plate having a plane upper surface and a lower surface in the form of an inverted polygonal pyramid, a central pilot burner underlying the vertex of said lower surface, and a second burner surrounding said central pilot burner and underlying the relatively thick central portion of said stove top.
2. In a stove assembly, the combination of a stove top comprising a solid plate of metal of high heat conductivity having a plane upper surface and a lower surface so formed that the thickness of said plate increases uniformly from relatively thin edges to a relatively thick central portion, a central aperture through said plate, a central pilot burner underlying said aperture and a second burner surrounding said pilot burner and underlying the relatively thick central portion of said plate.
3. A stove top adapted to be uniformly heated by means of a central burner comprising a solid metal plate having a plane upper surface and a lower surface in the form of an inverted polygonal pyramid, the thickness of the solid metal plate at any given point being inversely proportional to the horizontal distance of said point from the vertex of said lower surface whereby heat applied at the vertex of said lower surface is conducted through a substantially greater thickness of solid metal than heat applied to other portions of said lower surface.
