LOUIS, MISSOURI, A CORPORATION OF NEW JERSEY GAS RANGE Application filed January 3, 1930, Serial No. 418,381. Renewed December 14, 1931,

This invention relates to ini n'ovements in gas ranges.

One of the objects of the invention is the provision in a single range of a combined right and left hand oven range.

Another object of the invention is the pro-- Vision of'a range which lends itself to the insulation of the baking oven more readily.

Another object of the invention is the In provision of an improved gas range which is very symmetrical and pleasing in appearance.

A still further object of the invention is the provision of a gas range of the thermol5 statically controlled type in which the thermostat control housing is completely encased and hidden from View and in which all of the gas pipes, burners, manifolds and valves are completely encased and hidden from View all to the end of making a range of more pleasing appearance.

Another and further object of the invention is the provision of swinging covers for completely housing and hiding from View the cooking top portions of the range when the cooking top'portions are not in use.

Other novel features of construction, improved results and advantages of the invention will appear from the following description and accompanying drawings.

In the drawings:

Figure 1 is a perspective View of agas range embodying the present invention, portions of the view being broken away and shown in section to more clearly illustrate the constructional features.

a, Fig. 2 is a top plan view, a portion of the broiling oven top being broken away'and the parts'therebcneath being shown in horizontal section to more clearly illustrate the constructional features of the range.

Fig. 3 is a top plan view of the burner, gas supply pipe and valve arrangement of the cooking top portion of the range.

Fig. 4 is a view in side elevation of the burners appearing in Figure 3, a portion of the figure being shown in vertical section.

To successfully manufacture and sell gas ranges it is essential that the manufacturer keep closely in touch and follow the trend ventional legs 5 and that supported upon 7 of public demand and the present range has been conceived to meet such demand, which at the present time is that gas ranges be more pleasing in appearance and have incorporated in their construction all of the improved features for a convenient, easy and highly efficient operation and use.

It "has always been the practice of gas stove manufacturers to make what are known as right and left hand models. Right hand model ranges have the cooking and broiling ovens at the right side or end of the range while the left hand models are of course the reverse. The range of the present invention eliminates the necessity of two models inasmuch as it combines in a single range both the right and left hand models by having the cooking and broiling ovens centrally ar-' ranged with cooking top portions at either side thereof.

Describing the invention in broad terms it will be seen by reference to Figures 1 and 2 of the drawings that there is provided a stove base A supported upon the usual conthis base central of its length is a cooking oven B upon which is superimposed a broil ing oven C. At either side of the broiling oven are the cooking top portions D and E of the range immediately beneath which are the burner chambers F and G in which are mounted the front burners H and the rear burners J. These burner chambers are-closed at their front ends by panels 6 and 7.

Immediately below the burner chambers and at either side of the cooking oven are the utensil compartments K and'L.

Describing the invention in more detail it will be seen that access is had to the cooking oven through a swinging door 8 and that entrance to the broiling oven is through a swinging door 9 both of which are provided with the usual handles 10. The burner in the cooking oven is of a U-shape as designated at 11 while the burner in the broiling oven is of a rectangular shape as designated at 12.

The cooking tops D and E are bordered by angle iron frames 13 in which are removably supported suitable grids 14. Extending 100 transverse each of the cooking top portions of the range are burner supporting rods 15.

Fuel for the range is brought from a suitable source of supply through a pipe 16 which enters the rear of the range into the rear end of the cooking oven where it has connection with the supply pipe 17 which runs lengthwise of the rear of the range. This pipe 17 has portions 18 and- 19 which parallel the end walls 20 of the range to a point adjacent the front of the range and then turns so that their portions 21 and 22 parallel the panels 6 and 7 immediately below the front ends of the burner top frames 13.

Immediately behind the concealingpanels 6 and 7 are the gas valves 23 which are threadedly connected to and supported by the supply pipes as indicated at 24. These valves have elongated jets 25 which extend rearwardly into the burner chambers.

The burners H and J have tubular burner portions 26 provided in their upper ends with burner orifices 27. Struck out from the bottom of these tubular portions 26 are tongues 28 which have at one side adjacent their inner-ends a shoulder or abutment 29. The burner supporting rods 15 are provided with openings 30 of a size to loosely receive the tongues 28 of the burners and when the tongues are inserted into the rod openings the shoulder 29 forms an abutment or stop.

The mixing tubes of the burners are designated at 31 and terminate in mixing chambers 32 the lower ends 33 of which are open. Suitable conventional shutters 34 control the admission of air into these mixing chambers. The jets 25 of the valves extend through the end walls 35 of the mixing chambers into the interior thereof and support burners at their upper ends. It will therefore be apparent that the burners are supported by the burner rods 15 and the valves 23.

The valves illustrated in the drawings are of the rotary type and are provided with elongated rods 36 which extend through the front concealing panels 6 and 7 and carry attheir outer ends the valve operating handles 37.

Mounted upon the side wall of the cooking oven and within the burner chamber F is the housing 38 carrying the thermostatic control mechanism.

The thermostatic element is designated at 39 and is positioned within the front upper end of the cooking oven. The thermostatic control wheel 40 for setting the thermostat is positioned adjacent the upper front edge of one end of the range and has operative connection with the mechanism within the hous ing 38 through the medium of an elongated rod 41 which extends transverse the burner chamber F. Gas is taken from the supply pipe portion 21 through a pipe 42 into the thermostatic housing 38 and is led' from there by a pipe 43 down to the mixing bell 44 of the cooking oven burner 11. It will be readv,

ily apparent that all of the pipes and hous-e ings above referred to are concealed from broiling burner has communication with the atmosphere at 48- through the broiler oven side wall 49.

Gas supply to the cooking and broiling oven burner is controlled by the valves 50 and 51 respectively.

The products of combustion from the cooking and broiling ovens is carried off by a suitable flue 52.

Entrance to the utensil" compartment is shown as being had through doors 45 and 53 provided with suitable handles 54;, but it will be obvious that sliding drawers could be substituted for this construction without departing from the spirit of the invention.

The cooking tops at the ends of the range are one burner wide and two burners deep so that the two taken together provide four cooking top burners which is the number usually found in the conventional type of gas range in common use.

It has proven desirable to provide means for hiding the cooking top portions of the range from view when they are not in use and to this end there is provided the swinging covers or housings X and Y. These hous ings are pivotally supported as at 55 upon the cooking top frames 13 so that they may be readily swung up or down by the handles 56.

These covers have side walls 57 and 58,

a top 59 and front walls 60 so that when they are in a lowered position they completely conceal the cooking top portion of the range yet form a housing thereabove so that they can be lowered and still accommodate cooking 4 utensils which might be left upon the grids of the cooking top portion of the range.

As will be readily apparent the broiling oven extends considerably above the cooking top portion of the range which is a more or less conventional construction. For the purpose of lending to the appearance of the range when the covers X and Y are lowered these covers are made of a depth or have a side wall height equal to the height of the broiler oven above the cooking top portion of the range so that when the swinging covers are lowered their tops 59 are flush with the top 61 of the broiling oven as is clearly illustrated in Figure 1 of the drawings.

That a range constructed in accordance with this invention clearly lends itself to the insu ation of the baking oven is readily apparent in Figure 1 of the drawings, as here it will be seen that only the front and back of the oven are exposed.

An examination of Figure 1 of the drawings will also clearly show that the range is very pleasing in appearance when the swingj ing covers are lowered as none of" the operating portions of the range are visible and it will also be readily seen that even with the covers in their raised position that all of the burners, gas valves, gas manifolds, thermostatic housings, and like parts are completely concealed from view.

Attention is directed to the fact that when the cooking top swinging covers are in their elevated positions that their side walls 57 and 58 and the rear wall 59 form splash plates at the rear end of the cooking top portions to prevent the splattering of grease or dirt upon the walls of the room in which the range is installed.

Access can be had to the burners and valves by merely removing the grids from the cooking top and it will also be readily apparent that the burners themselves can be readily removed from their supports.
