Mann/1 A Patented Sept. 15, 1936 UNITED STATES PATENT OFFICE 5 Claims.

This invention relates to gas ranges and particularly to those which utilize a table top, as a working surface, apart from the burner grids. Heretofore, the cooking burners, which usually are four in number have been arranged in the form of a rectangle at one side of the range and have occupied approximately one-half of the available space on the top of the range. The remaining space has been used as a working surface, but it has been located directly over the oven, where it is too hot to be of general use while the oven burner is in operation.

One of the objects of my invention therefore, is to provide an arrangement of burners by means of which approximately one-half the top surface is available as a working surface, and in which half of it is located above the oven and the remainder above the usual utensil compartment. In this way, I obtain a hot working surface, and a cold working surface, whenever the oven is in use.

The arrangement of burners which my invention seeks to accomplish is diflicult of attainment if the usual compact arrangement of valve handles is disposed directly in front of its associated burner, the space requirements would.

necessitate an oven that is too small in height to be practical. Accordingly, I have devised a control arrangement by means of which the gas valves may be compactly arranged at one side of the oven, and by means of which the burners may be located in any desired position with relation to the top of the range. Moreover, I have devised an arrangement wherein the valves are maintained in a cool region at all times, and wherein the adjusting mechanism for controlling the mixture of gas and air is readily accessible for each burner.

' A further consideration in connection with table top ranges is the fact that the'broiler compartment is located directly beneath the oven and is therefore, too low for convenience.

A further object of my invention therefore, is to maintain the broiler beneath the oven, which is the most logical position from a standpoint of manufacture and utility, and yet, to make it as reasonably convenient for use, as is the oven.

An additional object is to provide an arrangement which will increase the efficiency of the burner operation, and yet will conceal all of the mechanism except the gas outlet openings.

Referring now to the drawings, Fig. 1 is a front elevation of a stove embodying my invention; Fig. 2 is a top plan View thereof; Figs. 3, 4 and 5 are sections taken on the correspondingly numbered lines in Fig. 1; Fig. 6 is a sectional view through a broiler drawer having a modified form of pan support, and Fig. '7 is a section taken on an enlarged scale through a burner and on the line 1-1 in Fig. 3.

The stove, which I have illustrated has a top In, end walls II, and a back wall 5. The front wall is formed by an oven closure I2, a broiler closure l3 and a utensil compartment closure I4. The burner arrangement for cooking purposes is illustrated in Fig. 2 as comprising four burners l5 which are arranged in longitudinal alignment in the rear portion of the range top. The burner openings are preferably oval in shape and are provided with grids in the usual manner. By arranging the burners in the manner illustrated and described, it is apparent that substantially one-half of the top surface is available for a working surface, and that there is no necessity to reach across one burner while handling a utensil on another, and that there is therefore, no danger of burning the wearing apparel of the user.

To maintain a compact arrangement of the fuel control handles at one side of the oven, I provide a manifold 20 which is disposed within the range and in the upper portion of the utensil compartment. The manifold is connected to a supply pipe 2|, which is shown, as entering the range from the rear thereof.

A valve 22 is connected to the manifold for each of the cooking burners, and each is controlled by rotatable rod 23 which extends to the front Wall and is provided with a knob 24. In the preferred arrangement the. manifold and associated valves are disposed beneath a partition 25, as is shown in Fig. 4, and hence are in a region in which the temperature is substantially uniform. Thus, there is no danger of the valves sticking on account of their subjection to an excessive degree of heat.

To connect the supply valves with the burners, I provide flexible tubing 26, as is shown in Fig. 3, and I extend each tube from one of the valves to an outlet, which is located adjacent each burner inlet. In Fig. '7, the burner inlet is indicated at 28, at which point the usual air control disc valve is located, and at such point, I provide a needle valve or orifice, indicated in general at 29. By making the openings oval in shape, as heretofore described, and by locating the needle valves at the inlet end of a goose neck tube 30, the needle valves are readily accessible from the top of the stove for inspection and adjustment. Such mechanism may normally be concealed from view,

however, by a curved plate 3| which is supported on the range top beneath the periphery of the grids 32, and which extends downwardly and terminates in an opening that is sufficiently large to enclose the burner. The curved plates have a two-fold use, in that they conceal the fuel adjustment members and direct secondary air into the burners, through the openings between the burner arms.

In Figs. 3 and 7 I have shown a plate 9, which extends longitudinally of the stove and which provides a supporting medium for a plurality of burners. The plate has rigidly fastened thereto, as by welding, a bracket 8, which is shown as a U-shaped member, one leg of which supports the gas conduit 26, and the other leg of which supports a cross plate 1 upon which the burner rests.

To utilize the space over the oven for cooking burners and at the same time to provide an oven .which has a maximum height, I utilize a false oven top 33, which extends downwardly from the oven front in an inclined direction and thence laterally in ahorizontal direction, as is shown in Fig. 5. The horizontally extending portion then provides a support for the two burners, which are located above the oven and enable them to be positioned at the same level as the remaining burners.

The broiler compartment closure is preferably a drawer, which is slidably positioned within the compartment. The drawer has a pan support 35,

that is provided with elevating means to vary its I position vertically with reference to the drawer. In the preferred arrangement, such means comprises a threaded spindle 36 which is attached to the pan, and which in turn engages a correspondingly threaded socket in a pedestal 31. Thus, the pan support may be elevated or lowered merely by turning it on its axis.

In Fig. 5, the pedestal is illustrated as being mounted directly upon the bottom of the drawer in which case, it is rigidly fastened thereto. In Fig. 6 however, the pedestal is shown as being fastened to a false bottom 38 wherefore, it can be removed as a unit from the drawer, whenever desired, as for instance to insert a large roasting pan.

The utensil compartment closure is preferably mounted on concealed hinges, along the line 39, to swing outwardly, and so it is provided with clearance openings 40 for the valve operating knobs 24. I have shown only four knobs exposed in view, and so provision must be made for the oven burner valve and oven heat control mechanism. These are preferably mounted within'the utensil compartment, just below the valve rods 23 where they are readily accessible in the utensil compartment, just below the valve rods 23 where they are readily accessible, whenever the utensil compartment door is opened. I prefer to locate the oven and broiler control mechanism in a concealed location, for they are used so infrequently, that I deem it advisable to avoid exposed valve operating members as much as possible.

A further feature of my range is the use of a splash plate, which is connected to the back of the stove and which is provided wit brackets 4| that extend forwardly from it, and t ence downwardly and are attached to the top I0. In the preferred arrangement, the forward ends of the brackets terminate adjacent the forward ends of the burners, and thus provide guards for holding utensils on the range.

The stove legs 42 are preferably U-shaped tubular members that are attached to the bottom of the range and that extend from the front to rear as is shown in Fig. 4. These supports provide a sturdy construction that can be installed at the factory and shipped with the range, whereas in prior constructions, the practice has been to ship the legs with the stove in dismantled condition.

From the foregoing description, it will be apparent that I have provided a stove, which has many advantages over prior ranges, and which provides a compact structure that may be made principally of pressed steel parts, and therefore produced at low cost,
