Gardiner,y University City, Mo., assigner-s to Majestic Manufacturing Company, St. Louis, Mo., a corporation of Missouri Application October 30, 1944, Serial No. 560,922 1 claim. (c1. 12e- 1) rIhis invention relates to improvements in a range construction, particularly of the type wherein the fuel employed is either coal or wood.

One object of the invention is a provision o'f a novel oven and oven surrounding ue arrangement adapted to produce a maximum in heat efciency. A second object is to provide novel clean-up means whereby removal of accumulated soot is facilitated.

A further object is to provide a novel arrangement in conjunction with a removable ash pan adapted to seal the opening for said pan when the latter is in place, thus obviating the escape of fly ash into the kitchen when shaking the grates.

Other advantages and features of the invention will be noted in the description to follow, reference being had to the drawings which form part of this specification. The specific construction illustrated is a preferred one, which is subject, of course, to modifications within the scope of the appended claim.

In said drawings: y

Fig. 9 is a vertical sectional View on the lines 9 9 in Figs. 2 and 4; and

Fig. 10 is a fragmentary side elevational view of an ash pan construction.

The range, generally indicated A, is mounted on and supported by a suitable base B. A conventional oven door C and a re door D of the concealed hinge type are provided, as are ornamental panels E and F and the usual back guard G.

The interior construction of the range body is such that there is provided a rebox and grate assembly compartment I3, an ash compartment I4 therebelow, an oven or a baking chamber I5, a horizontal ue i6 above the oven, a vertical flue Il at one side thereof, a horizontal flue I8 beneath the oven, and a vertical ue I9 at the rear of the oven.

The compartment I3 is adapted to receive a conventional firebox and grate assembly, generally indicated 26 and outlined in broken lines. This compartment is dened by said grating, the left end of the wall 2 I of the range body or casing, the front and rear walls 22' and 23, respectively, of the range body, the Cooktop 24, and the upper portion of a vertical wall included in the oven structure te be described hereinafter.

The ash compartment I4 is similarly defined with one exception, namely, the substitution of the range body bottom plate 25 for the cooktop 2A in the above description.

As shown in the drawings, the oven is unique in that it is formed by two complementary components, generally designated 26 and 21. The member 29, forming the side and top walls, is of inverted channelshaped cross section,4 one vertical side portibn 28 thereof forming the left hand wall, the opposite vertical side portion 29 forming the right hand wall, and the connecting or web portion 39 forming the top wall of the oven. The member 23 extends from the front wall 22 of the stove to the rear wall 23 thereof, and the side walls 28 and 29 of the member` 26 rest-upon the bottom wall 25. The member 2'1, forming the bottom and rear walls, is L-shaped in cross section, the horizontal portion 3| forming the bot-'- torn wall of the oven, and the vertical portion 32 thereof forming the rear wall of said oven. The member 27 is inserted into the member 26, with the bottom wall 3| secured to the side walls 2'8 and 29 above the bottoms thereof, and with the back wall 32 secured to the side walls 28 and 29, and the top wall 3l), but spaced inwardly from the main back panel 23.

The upper horizontal flue I6 is defined by the front and rear casing walls 22 and 23, the top wall 39 of the oven and the Cooktop 2A. The vertical down-flue Il at the right end of the range is defined by the front and rear casing walls 22 and 23, the oven Side wall 2'9, and the right hand end casing wall 33.

The lower horizontal flue I8 below the oven is defined by the front and rear walls 22 and 23, the walls 28, 29 and 9| of the oven, and the body bottom 25. Y

The vertical flue I9 at the rear of the oven is defined by the rear wall 23 of the casing, a portion of the side walls 28 and 29 of the oven, the oven back wall 32, the bottom plate 25, and the baketop 24.

As shown in the drawings, all of the various casing, oven and flue walls or partitions are provided Vwith flanges whereby they may 4'be spotwelded, bolted, or otherwise secured to one another to form a rigid, compact structure.

In addition to an oven opening, the front Wall 22 is provided with a rectangular opening 3ft having an inwardly turned flange 35. This opening is adapted to receive a removable ashpan 36 which extends rearwardly from said opening to a point in the ash compartment ld adjacent the rear wall 23 of the oven body. The opening 34 is considerably larger than necessary to accommodate the removal and replacement of the ashpan.

A cover plate 31, provided with a handle 38, is of a size large enough to completely seal the opening 34 by engagement with the front wall 22 around the opening. The cover plate 31 is maintained in rigid spaced relation to the front wall 39 of the ashpan by means of a flanged, U-shaped bracket ci), welded or otherwise rigidly secured to the cover plate 31 and to the wall 39. The arrangement is such that a downwardly opening notch 4l (Fig. l0) is formed between the cover plate 31, the front wall 39 of the ashpan, and the bottom of the bracket 43. When the ashpan is in place, the notch Si is of a size to engage over the bottom 35' of the inturned flange portion 35 (Fig. 5). By means of this notch engageable with the flange, the entire ashpan proper is suspended and supported wholly on the flange 35 by the bracket s@ in conjunction with the cover plate 31. In this manner, due to the weight of the ashpan, the cover plate 31 is caused to impinge against the outer face of the front wall 22, thus completely sealing the opening 34 to prevent any possibility of fly ash escaping into the room when shaking the grates. The fire door D may be suitably recessed to accommodate the handle 38. As shown, particularly in Fig. 9, a deflector 42 may be secured to the wall 28 to assist in depositing ashes into the pan.

The rear wall 23 has an opening 43 provided with a suitable draft regulating device 43 disposed below the level of the grates. It also has two vertically spaced openings Q and 4G, both leading into a smoke-box 31 provided with an upstanding flange 48 to support the usual stove pipe 42, shown in broken lines. The opening d6 is provided with a damper 50 operable by means of a handle 5l whereby the opening may be covered or uncovered. An access opening 52 is also provided in said rear wall. This opening is normally closed by means of a removable cover plate 53 provided with a knob.

A cleanout opening 53 is provided as shown in the lower portion of the wall 28. It is also nor- L The end mally closed by a similar cover plate 55. wall 23 has formed therein below the bottom of the oven a flue opening 55. A diagonally extending baile plate '51 in the form of an angle is rigidly secured to the underside of the bottom plate 3l of the oven. It extends in the flue I8 from a point adjacent the rear end of the opening 56 forwardly to a point adjacent the left front corner of the oven, as best seen in Fig. 5. Its depth is such that its lower edge is spaced above the bottom 25.

The cooktop 2 is of conventional construction and is removably supported in a rectangular frame 5S suitably contoured to receive it.

Operation.

Assuming now that the range is to be used for cooking purposes only, and that the fuel indicated by broken lines in Fig. 9, has been ignited, the operating handle 5l is manipulated to 4 move the damper 50 to its open or broken line position shown in Fig. 7. Thereupon the hot gases and smoke emanating from the burning fuel are drawn into the smoke-box through the uncovered opening 46. That portion of the cooktop directlyabove the firebox compartment absorbs most of the heat at this time, as is understood.

Assuming, however, that the range is to be used primarily for baking purposes, the operating handle 5l is manipulated to move the damper 50 to its closed or full line position (Fig. '1). Thereupon the hot gases and smoke emanating from the burning fuel are drawn laterally across the horizontal flue I6, thence downwardly through the flue l1, thence through the opening 56 and laterally and diagonally across approximately one-half of the horizontal ue I8 (see arrows in Figs. 5 and 9). The diagonal path of the products of combustion from the opening 56 to a point adjacent the lower left front corner of the oven is effected by the baille 51.

The balile causes the larger part of them to pass around its left hand extremity (see Fig. 5), whence they are drawn rearwardly across the balance of the ilue I8, and next upwardly through the vertical flue I9, and by way of the opening 45 into the smoke box d1.

With the above circuitous flue arrangement, it is evident that the entire top wall of the oven, its entire bottom and rear wall, its entire right side wall, and a substantial portion of its left side wall areexposed to, and in a position to, absorb the heat from the products of combustion originating in the rebox.

Thus, uniformity of temperature is had throughout the entire expanse of the oven, a condition conducive to best baking results.

The accumulation of soot in a range of the present type is unavoidable. A novel arrangement to facilitate its removal is embodied in the present construction. By removing the cover plate 53, which is normally held in place by a latch, or in any other suitable manner, access is afforded a conventional scraper to any and all walls defining the vertical flue I9. The dislodged particles cf soot come to rest upon the bottom plate 25 of the horizontal flue i3.

The vertical flue l1 has little or no tendency to accumulate soot. The horizontal flue I8, however, does accumulate a considerable amount and requires cleaning from time to time.

To remove the soot in this iiue, including that scraped from the flue I9, it is only necessary to remove the ashpan and then the cover plate 55, whereupon a conventional scraper may be inserted through the opening 5d to scrape the soot into the ash compartment. The baile 5i may be cleaned concurrently. Should the flue l5 require cleaning, the scraper may be inserted for this purpose by removing one or more cooking lids.

Obviously, the embodiment illustrated may be modified in some respects without departing from the scope of the invention.

What is claimed is:

Range construction comprising an ash compartment dened by walls including a front Wall, an opening -in said front wall for insertion into and removal from said compartment of an ashpan including a lower edge formed as an inwardly directed horizontal ange, an ashpan disposed in said compartment, and means supporting said ashpan in suspended relation in said compartment o n said lower edge including a bracket secured to the front end of said aslipan above the lower edge thereof and a closure plate for the opening secured to said bracket and depending therebelow, said closure plate being spaced from the front surface of the ashpan, said bracket resting on said lower flanged edge of said opening with said closure plate 5 biased against the outer surface of the front wall in sealing relation by the weight of said ashpan disposed in said compartment, said ashpan depending below the said lower anged edge and bearing against the inwardly directed edge thereof.
