12 Claims.

v Theinvention pertains to cook stoves or ranges and has more particular' reference to an improved mode of construction for stoves of the socalled table top type.

The object of the invention is to produce a practical stove construction of the character indicated at a lower cost than has heretofore been possible without sacrificing neatness of appearance, rigidity, and durability.

In the accompanying drawings,

Figure 1 is a fragmentary front elevational view of a stove embodying my invention.

Fig` 2 is an end view with parts broken away to show details of construction.

Fig. 3 is an exploded perspective view showing various parts employed in constructing the stove body.

Fig. 4 is a fragmentary perspective view illustrating the matter ofl mounting and guiding 20 the utility drawer.

Fig. 5 is a fragmentary transverse sectional view through the front frame and the forward edge portion of the central partition wall between the oven section and lthe cooking top section.

The improved stove is built up from a number of sections or units separately constructed and enameled and subsequently assembled into a rigid structure. While the number and charac- 30 ter of the units may vary, they include inthe present instance two major units of which one is a base unit providing a base frame 7, an intermediate vertical partition plate 8, and a rear wall plate formed from one sheet of metal and providing rear walls 9 and 10 for the oven and cooking top sections respectively; and the other an inner oven unit generally U-shaped in form and having parallel inner

side wall plates

11 and 12, an inner top Wall plate 13, and an 40 inner rear'wall plate 14. In the embodiment herein shown, the oven section is of the insulated type and the inner oven unit is mounted at one end of the base frame in cooperative relation to the partition plate 8 and the rear wall 9 of the base unit to form two of the outer side plates of the oven section.

To the two major units assembled as above indicated, I apply a plurality ci auxiliary units. Thus two separately formed outer side or

end plates

15 and 16 are mounted at opposite ends of the base frame; a top plate 17 overlies both the major units; and a front frame 18 substantially completes the body. The partition plate 8 of the base unit forms the inner end wall of the cooking top section of the stove, and the end plate 16 forms the outer end wall of said section, the rear wall 10 thereof being formed by the rear plate of the base unit. One end of the top plate 17 forms a top nishing plate 17a and the other end is cut away to form a cooking top frame 19. The front frame unit 18 provides door frames for the usual closures including, in the present instance, an oven door 21 (Fig. 1), a broiler door front 22, two utility door fronts 23 and 23a, and a manifold cover plate 24.

The base frame 7 as herein shown (Figs. 1 and 3)` is made from a single elongated sheet of relatively heavy gage metal rectangular in form and having opposite end portions of substantial size cut out so as to form front and

rear frame members

25 and 26, end members 27 and 28, and a relatively wide central frame member 29. The portions of the plate thus remoied in forming the base framemay, of course, be utilized in making other parts of the stove. For the sake of rigidity, the opposite side edges of each of the frame members is anged downwardly so as to make the frame members of substantially inverted channel form. The intermediate partition plate 8 of the base unit is lsuitably secured in position approximately centrally of the intermediate frame member 29 of the base, being `for this purpose provided with a flange 30 which is spot welded to the base frame. The rear walls 9 and 10 are as above indicated formed from one sheet of metal which is secured to the rear depending ilange of the base frame and to a flange at the rear edge of the partition plate 8. Preferably these parts are secured together by spot welding. l

The

plates

11, 12 and 14 of the inner oven unit are preferably'made from a single sheet of metal, and are preferably secured to the top plate 13 by spot welding, said plate 13 having for this purpose upturned anges at each of its edges, as shown clearly in Fig. 3. At the lower edges of the

plates

11, 12 and 14 inturned :flanges 31, 32 and 33 are provided, these flanges being apertured for the purpose of bolting the inner oven section in position on the base frame, which latter for this purpose is provided with suitable openings 34. Similarly, the side plates 1l and 12 are provided at their front edges with apertured outturned flanges 35 and 36 adapted to be secured to the main :iront frame in a manner which will later be described. if

The outer side plate l5 of the oven section is mounted in interengaging relation to the frame f 55 serving to space the oven top plate 18 from insulation material.

member 27 of the base frame and for this purpose carries at its lower edge and upon the inner side thereof a plurality of bracket members forming hooks 39 spot welded to an outwardly offset lower marginal portion 40 of the plate 15. The hooks 39 have down-turned tongues 41 adapted to enter slots 42 formed in the frame member 27. At its front and rear edges the plate 15 has anges 43 and 43H reue space thus formed communicates at its rear` edge through an opening 47 with a space between the inner rear plate 14 and the outer' rear wall plate 9 of the oven section, the latter being provided with a flue hole 48 (Fig. 3). The forward edge of the inner top plate 13 of the oven terminates short of the corresponding edge of the plate 44 to form a passage 49 (Fig. 2) to permit the passage of products of combustion upwardly into the ilue space between the

plates

13 and 44, and preferably baille plates 50 are secured on the plate 13 to retard the passage of the hot gases to the opening 47 at the rear.

'Ihe top plate 17 is formed from aflat sheet of metal andhas down-turned flanges at each of its four edges. The end plate 17 overlies the oven section and the side flanges arel so proportioned as to fit downwardly over the upper edges of the front 'frame and the plates 9 and 15. Thus a front flange 51 is arranged to t over the upper edge portion of the, front frame 18 (Figs. 2 and 3); a rear flange 52 fits downwardly over the upper edge of the rear plate 9 and is secured thereto by means of screws; and an end flange 53 with inturned edges engages the upper edge portion of the end plate 15.

At the front and rear edges of the intermediate plate 44 are upstanding flanges 54 and the plate 44, this space being preferably filled with suitable insulating material 56 (Fig. 2). The spaces formed within the hollow side walls of the oven are, of course, similarly filled with The outer end plate 16 of the cooking top section is mounted on the base frame ina manner similar to the plate 15 of the oven section, being for this purpose provided with hooks 57 en- 'gaging in slots in the frame member 28 of the section.' For this purpose the rear flange 52 of the top plate ts downwardly over the upper edge of the rear plate 10 and secured thereto; and the end ilange 53"i engages the upper outer edge of the end plate 16. Seated within the frame 19 is a burner top plate 62 formed of sheet neemt? metal and having openings for the top burner of which only one is shown at 63.

The main front frame unit 18 is formed from two

castings

64 and 65 each substantially rectangular in form and secured together so as to provide an oven door frame 66, a broiler drawer frame 67, and a front frame 68 for the cooking top section. The two castings Gil-and 65 are preferably secured together by means of screws 69 (Fig. 5), the two parts having an interiltting relation for this purpose with the casting 64 formed with an extension 70 overlapped byv a channel shaped section 7()a of the casting 65.

The frame 18 thus constructedis applied to the front of the oven unit and the open top section after the latter have been assembled and suitably secured in position. In the present instance, the lower frame members are provided with a plurality of inwardly projecting bosses 71 of which one is shown in Fig. 2 to receive screws entered through the down-turned flange at the front of the base frame from the inner side thereof, said flange being provided with suitable openings 72 for this purpose. In fastening the end plate ilange 59 to the front frame, bosses similar to the bosses 71 may be provided on the end member of the frame to receive screws entered through apertures 72a in the flange 59 of the end plate 16.

At the upper front edges of the two major sections the frame 18 is secured in position by means of bolts 73 (Fig. 2) entered through angle brackets 74 spot welded to the underside of the top finishing plate 17 and depending therefrom in rearwardly spaced relation `to the front ange 51 of the top plate. To receive the bolts 73, the front frame is'provided with apertures 75 formed in the closure seating flanges 76 of the frame.

As shown in Fig. 5, the front frame member is provided with lugs 77 and 77a forming with parts of the front castings grooves for receiving the" front edge portions of the oven wall plates 8 and 11. At its upper edge the plate 8 is flanged as at 8 for engagement with the underside of the u top plate 17. f

Within the oven section is a horizontal partition 78 dividing the same into an upper or baking oven and a lower or broiler oven. Beneath the partition 78 is an oven burner 81 supported in any suitable manner. broiler drawer suitably mounted for front to rear sliding movement on tracks 83, which latter may be spot welded to the frame members 27 and 29 of the base. 84 designates roller brackets for additionally supporting and guiding the drawer whose front 22 is arranged to seat in the frame 67 of the front frame unit. Inasmuch as the broiler drawer structure forms no part of the invention, it need not be described in detail.

The main oven door 21 is suitably hinged at its lower edge, the hinges being generally designated in Fig. 2.

The cooking top section provides in its upper portion a burner box in which is supported, preferably by means of the front frame, a manifold 86 for supplying the top burners. A front cover plate 24 pivotally mounted on hinge brackets 88 servesto close the burner box.

'Ihe lower portion of the cooking top section provides a compartment having in the present 82 designates generally a l drawer carry guide brackets 91 engaging the tracks (see Fig. 4) to hold th drawer in position thereon. 92 (Fig. 4) are stopfingers formed on the tracks to limit the outward movement of the drawer. The upper drawer may be mounted for front to rear sliding movement in any preferred manner.

To support the body of the stove, legs 93 are fastened at the corners of the base frame which for this purpose is provided with corner brackets 94 substantially triangular in form and having upstanding corner flanges 95 adapted to t snugly within the corners of the ybase frame formed by the outer depending flanges. The iianges are spot welded to the down-turned flanges of the base frame. The legs have top plates 96 which are secured to the corner brackets as by means of bolts 97 which are entered from beneath and engage in tapped holes in the corner brackets.

The rear edge of the stove body may have secured thereto a back plate 98. 100 designates generally a towel bar of U-shaped form having its legs slidably mounted within the flue space between lthe inner oven plate 13 and the intermediate top plate 44, and its bight projecting outwardly to the outer side of the oven section.

By reason of the construction above set forth, it is possible to reduce substantially the cost of manufacture due principally to the fact that the stove is composed of separate units each having its several component parts secured together and completely enameled before being assembled with other units. Thus the base unit consisting in the present instance of the` base frame 7, vertical partition plate 8, and rear wall plates 9 and 10, together with the broiler and utility drawer guide tracks, is constructed, assembled and enameled as a unit. Similarly, the inner oven unit is completely constructed and enameled and thereupon secured in cooperative relation to the base unit, whereupon the

end plate units

15 and 16 and the front frame unit 18, each having been previously enameled, are applied to the base and oven units. Finally the body is completed by the application of the top plate 17, it being observed that the plate 17 engages with the

end plates

15 and 16 to hold them in position.

It will also be observed that the front frame unit is secured in position in such a way that when the several closure members arev in closed position no bolts or screws are exposed, and the end plates l5 and 16 are similarly mounted so ,as to leave no exposed fastening devices Thus I'have provided a method of stove construction which not only permits of a reduced cost of manufacture and a rigid construction, but which also renders it possible to obtain a neat and attractive appearance.
