Patented Feb. 23, 1954 UNIT. ED PAT 1 Claim; 1:
The'robjectnof this: invention is to devisev'a novel range of the dualfuel type,-and ;while: the range is primarily designedizto use oil or. gas/as a fuel, it is practical tov substituteaelectric elements for the gas so thattherangecan use :oil
and electricity.
A furtherobject of the invention is'ito design a range wherein the oven bottom is heated directly by the oil burner; and the hot gases pass up through flues at each side of theoven compartment and leave throughan uncontrolledfiue In the conventional range, the oven is heated by a burner locatedin acompartment adjacent to one side of, the oven, andthe gases are drawn across the; top of the even, down one side and finally underneath :theovento pass to the chimney or outlet for the'products of combustion; By direct bottom, heating, a more effective circulation of air in the oven is ob tained, and food may be cooked on oven racks rather than on theoven bottom, which doubles the capacityrof the oven sincetwo racksmay be used, whereas in the conventionalrange only the oven bottom is available.
A further object of the invention is to devise an oven and heating arrangement which does not require a fairly strongchimney draft and which will vent itself, 'sincethe only function of the chimney is to carry off the productsof. combustion. In the present type of ranges, a chimney draft is required to. draw-vthe products of combustion around the oven, and, if there is a leak insome part of the range=adjacent to, the flue, infiltration of heated airfrom thewoven into the flue causes inefficiency or may cause cold air to be drawn into the oven with the result that there is difficulty in heating up the'oven. In the present invention, as theoven' heats, a natural draft'is set up in the oven compartment causing circulation of air from the bottom to the-top of the oven. A small partof this air willleave through the outlet and-be-replaced by air at room temperature entering through the airintake. This latter air, however; will be heated by the oil burner and passes -upinto the oven-"compartment as heated air.
A further object of the invention is to devise a novel construction whichjvvillv eliminate, the necessity of employing'a damper at the outlet as has heretofore been deemed necessary to permit the oven to heat when using oil as a fuel. A certain amount of air is permitted to escape and the incoming air which replaces it is immediately heated by the burner.
With the foregoing and other objects in view as will. hereinafter clearly appeag; invention comprehendsahovel ,range o f thenual fueLtype.
A further obj ect, of the, invention is to, devise a novel ce t uct nia drran ementota ven and its intake and outlet, and novel means to effect the heating -of the oven bottom.

'The bottomof the oven isthusdirectly'heated by the oil burner'and the gpr oducts 'of, combustion pass from the side flue"l3' o'ver the top of'tlqije oven.
As the .oven heats" up, aynaturalfldraftis set up in the oven compartment g'causing circulation from-- the bottom, of the oven to its top: *Airat roomtemperature enters at air intake opening i5 and leaves the oven compartment atan outlet I6. This air entering" at intake gop enin jfilfi is heated by the oil burner B' -and passesgup; into Top cooking by oil Heat for top cooking with oil as a fuel is supplied by an oil burner l! fed by a conduit I 8 leading from an oil tank l9 supported on a bracket 20 at the rear of the range. The oil burner I! is in a compartment 2| above the oil tank 3 and such compartment has an insulated bottom 22. The products of combustion from the oil burner I! pass beneath the top cooking surface .23, provided with removablepot hole covers 24, and to the flue outlet l4. A limited amount of top cooking is provided by the products of combustion passing from the oil burner to the flue outlet l4. a
Top cooking with. gas 01; electricity V For top cooking with gas on electricity,'a: conventional arrangement of four units 25 is shown in the upper right hand compartmentjfi see Figure 2.
Oven heating with gas Heat for broiling For broiling, instead of using the oven for baking, a separate broiling compartment is provided so that the capacity of the range is increased since both ovens can be used at the same time.
A broiler compartment 29 is provided at one side of the baking oven and has its top and sides insulated, see Figure 2. The compartment 29 is provided with a broiler burner 30 and a flue outlet 3l. A broiler pan 32 is selectively positioned on guides 33.
The range has conventional insulated doors 3d, and its casing is supported on chambered base members 35 having levelling devices 39.
The oil burners may be single or double burners or multiple burners.
It will now be apparent that the oven is heated by oil directly from the bottom.
Heat for top cooking is supplied by a second burner in a separate compartment, although a portion of the heat from the oven burner can be utilized for a limited amount of top cooking.
By heating the oven with oil from the bottom, circulation is set up in the oven which permits food to be cooked on two racks, and it is not necessary to cook directly on the oven bottom.
The foregoing permits the design of the oven when operating with gas to be identical to that of a standard range oven for gas, whereas the conventional combination range requires a makeshift arrangement of the oven burner and various baflles which are usually removed when operating with oil.
No substantial or specific degree of chimney draft is required for the operation of the range. The only purpose which the chimney serves is to carry off the spent products of combustion from the oil burners.
The design aids in manufacturing since the joints in the fiues need not necessarily be tight. If the joints are not tight, the performance of the range is not afiected to any substantial degree.
The arrangement of the parts including the broiler unit is advantageous both from an operating and a construction viewpoint.
A damper is not necessary in the oven outlet. In prior ranges of this type, a damper has been deemed necessaary to permit the oven to heat when using oil as a fuel. In this invention, a certain amountof air is permitted 'to escape and the incoming air which replaces itis immediately heated by the oven burner.
The present design as illustrated permits substantial savings in manufacturing costs.
The oven and the broiling compartment can be used at the same time thus doubling the capacityof the range.
The oven is spaced from the compartments above the partition 1 to contribute to form the side fiues l2 and I3, and the oven is spaced from the top of the range to form a top flue leading to the outlet 14. The flue I3 leads to the top flue, and the inner wall" of the oil burner compartment 2! terminates adesired distance above the oil burner 11 for top cooking.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
In a combination range, a casing having a top cooking surface, a burner compartment beneath said top surface at one side of the range and adapted to contain a burner, a broilercompartment at the opposite side of the range and adapted to contain a burner, an oven having side walls spaced from walls of said compartments to form side fiues and spaced from said top surface to form a top flue in communication with the side fiues, said casing having an uncontrolled flue outletabove the top oven wall and communicating with the burner compartment, side fiues and top flue, a partition below the oven contributing with it to form a bottom flue communicating with the side fiues and provided with a central opening, an oil burner having a clearance in said opening for air admission and for applying heat centrally to the oven bottom, an apertured channel forming an air heating chamber and an air intake within the oven and extending laterally across the bottom above the oil burner, a bafile fixed in the oven above the air intake, and said oven adapted to accommodate a gas burner between the baffle and the air intake.
