6 Claims.

My invention relates 'to household stoves or ranges which have built in as a part thereof a gas operated air circulating heater, and relates more particularly, insofar as the present embodiment is concerned, to stoves or ranges of the type known as table top stoves.

An object of the invention is to provide a combination cooking and heater range having a relatively large capacity heater whose presence as part of the stove is practically indiscernible insofar as concerns the outward appearance of the stove, and at the same time the range retains the characteristic lines and dimensions of modern stoves not equipped with such heaters.

Another object of the invention is to provide a stove having a heater of the character described, in which the arrangement for the introduction of air for heating and for burning and the outlet of the heated air and of the burned products,

is conducive to efiiciency of operation of the way interfering with the full'use of such space for the purpose adapted.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.

Referring to said drawing:

Figure 1 is a perspective view of a range constructed in accordance with my invention.

Figure 2 is a fragmentary vertical sectional view taken of the range, the plane of the section being indicated by the line 2-2 of Figure 1.

Figure 3 is a fragmentary vertical sectional view of the front portion of the stove taken at right angles to Figure 2, the plane of the section being indicated by the line 3-3 of Figure 1.

Figure 4 is a horizontal sectional view of the range taken on the line 4-4 of Figure 2.

Figure 5 is a fragmentary vertical section simicluding the oven 3 and broiler 4 arranged below the level of the cooking top 5 and designed to be superimposed by a cover-plate I made up desirably of a pair 'of sections 8 and 9, the latter of which is hinged or otherwise mounted to permit of its being readily raised from or lowered down over the cooking top 5. The oven and broiler compartments are located beneath the section 8 and have provided at the front thereof doors I2 and I3 respectively.

Covered by the cooking plate 5 is a top gas burner chamber M in which is disposed burners l6 for heating the vessels on the plate. Beneath the chamber l4 and arranged in side by side relation is a warming compartment or closet I! and a heater compartment l8, the former being located between the heater compartment and the oven and broiler while the latter is positioned to lie at the side of the range with the side wall l9 thereof preferably defining a side end of the range. As here shown, the warming closet and heater compartment are coextensive in vertical length and are together coextensive in width and depth with the top gas burner chamber. A wall 20 separates the warming closet from the heater compartment and suitable runners 2| or the like are provided in the closet for the support of a pair of horizontally slidable drawers 22 and 23 arranged one above the other and movable into and out of the closet through the front opening 24 thereof. The compartment I1 is heated by the heat in compartment 18 and to some extent by the oven and broiler, and serves both as a warming and a utility compartment.

Within the compartment I8 is a relatively narrow vertical shell or casing 26 which provides a combustion chamber and extends, as here shown, practically from the front of the compartment to the rear wall 21 thereof. The casing, as will be clear from the drawing, is provided with a front wall 30 which is positioned inwardly of the forward edges of the walls l9 and 20, and the casing 26 is spaced somewhat inwardly from the front wall 28 and the rear wall 21 of the compartment, as well as from the walls 19 and!!! so as to define vertical passagesfor the heated air circulating through the compartment.

of the compartment, where it is supported on Desirably the casing extends upwardly from the bottom the bottom frame 29 0f the range, to a point well up near the top of the compartment and is pipe 32 which leads from the top of the chamber to a flue connection 33 at the rear of the range.

An important feature is the location and arrangement of the outlet opening 34 for the air heated and circulating through the heater compartment. As will be clear from Figures 1 and 2 such opening is located in the wall is and takes up practically the entireupper half of the wall so as to leave substantially exposed most of the upper half of the casing 26. By reason of the size and positioning of the opening, not only is there permitted a free discharge of the heated air but a large area for the most eflective heating by direct radiation is afforded. Desirably the opening is engaged by a grill 38 of ornamental nature, and a rack 31 for supporting dish towels, etc. for drying over the opening, is pivotally secured to the rear wall of the stove and arranged for normal positioning at the side of the stove directly above the opening.

It is to be particularly noted that since the heater unit or casing 28 is so relatively narrow, the width of the compartment 18 is required to be but a small. portion of the horizontal space beneath the top gas burner chamber. In this manner practically all of the space beneath the top gas burner chamber remains available for use as a warming closet and no increase in the width of the range is necessary for accommodating the heater.

In order that the range will retain in appearance the effect of compactness such as is so necessary, particularly in the table top type of stove, I arrange for covering the closet and heater compartment area at the front of the stove with the same members. As will be seen from Figure 1, the drawers 23 and 24 are provided with front panels 38 and 39 respectively, which together provide a complete closure for the closet when the drawers are fully inserted therein. The panels however, are not only large enough to enclose the warming closet, but are made wide enough so as to completely cover the entire front of the heater compartment as well. In accordance with the foregoing each panel is extended at the end adiacent the heater compartment an amount equal to the width of the latter and thus both panels in,

horizontal dimension will be coextensive and completely harmonize with the panel or covering 4| in front of the top gas burner chamber. It is important to note .that with this arrangement .there need be but a single vertical division line across the entire front of the stove, and since the panel 38 and the broiler door are co-terminous at the bottom and the meeting edges of the upper and lower panels and the meeting edges of the oven and broiler doors are arranged to be in horizontal registration, considerable harmony in the horizontal divisional lines is also main- 43 and the burner control valves 44, the handles 46 for which are located at the front of the perforated plate 4|. As will be clear from Figures 3 and -5, the space-42 is desirably partitioned offat least in part-from the portion of the chamher in which the burners are located, and such space 42 is open at the bottom so that air may enter same and pass out through the perforations in plate 4| after circulating over the manifold connections and control valves, and thus keeping the parts including the handles comparatively cool. Unless provision is otherwise made, when the panels 38 and 39 are in fully closed position very little air, particularly the relatively cool air from adjacent the bottom of the stove will find its way to the space 42. Heretofore, it has been sometimes attempted to provide for this desired delivery of cool air by perforating the bottom member of the drawer, but quite frequently in the use of the stove such perforations become inadvertently covered with articles placed in the drawer and as a result the flow of cool air to said space is seriously curtailed. In accordance with my invention, the panels for the drawers are formed hollow orotherwise constructed to provide a vertical passage, and the bottom member joins the panel at a point intermediate rows of openings 48 and 43 respectively disposed near the top andbottom of the inner wall of each panel. With this construction air may enter the open bottom of the closet and find its way through the panels to the space "notwithstanding the fact that the drawers may be fully closed and the bottom members thereof entirely covered.- In a somewhat similar way the air from adjacent the bottom of the stove may reach the portion of the space 42 over the heater compartment. In this connection, it is to be noted that by reason of the use and positioning of the front wall 28 not only will the heat from the compartment be effectively confined to the interior of the compartment, but a direct cold air passage will be afforded between such wall and the adjacent portion of the drawer panels even when the drawers are in fully closed position, cold air being admitted to the lower portion of such passage through the narrow space left between the side wall of the lower drawerand the adjacent vertical edge of the wall 28.

It is to be noted that by utilizing the drawer panels 38. and 38 for closing the area in front of the heater compartment, not only is the requirement for a separate door eliminated, but the attendant difliculty of providing a door knob or handle which would be practical and of a design in keeping with the long horizontally extending handles 5| on the panels and on the oven and broiler doors, does, not arise.'
