This invention relates to kitchen ranges and has for its object broadly the provision of reversely arrangeable burner box and combined oven and broiler units, the parts of which will be so constructed and arranged that the units may be assembled in their desired relationship without the use of bolts, clamps, or other fastening devices.

Another important object of the invention is the provision of a range of the character de scribed, the parts of which will be so constructed and arranged as to permit of the employment oil the same supply pipes in the two arrangements and without specially fitting or altering the shape andconstruction of such supply pipes. The invention in this regard contemplates the connec tion of the burner box manifold and the burners in the broiler compartment, together with the same section of pipe in the two arrangements.

Another important object of the invention is the provision of an improved range stove construction adapted especially, although not exclusively, for use in the production of a reversible range.

Another important object of the invention is the provision for the control for the burner of the oven both manually and by thermostat infiuence through the front of the oven so that the provision of these parts will in nowise interfere with the reversibility of the major units of the burner box and the combined oven and broiler assemblies.

Another important object of the invention is the provision of a hidden manifold in a reversible stove of improved construction and arrangement.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, when taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Fig. 14 is a partial transverse section through the bottom of the stove showing the mounting of the stove within the iron frame base.

For the purpose of illustrating my invention I have shown in Figs. 1 to 12 and 14 a stove construction comprising generally a frame IS, a combined oven and broiler unit l6 and a burner box unit II. The frame in the instant embodiment of the invention is shown in detail in Figs. 3, 4, and 14, from which it will be noted that the four legs 2| of suitable form and construction are provided at their tops with flat parts 22 arranged at right angles and adapted to receive angle iron rails 23 which may be bolted in place as indicated by reference character 24 in Fig. 14. The angle iron rails 23 are arranged so that the apex or corners of the angles are adjacent and with the opening through the frame.

In accordance with the present invention it is not necessary to bolt or otherwise secure the burner box unit and/or the combined oven and broiler unit together or to the frame work itself. 40 The combined oven and broiler unit l6 and burner box unit I1 are so constructed that they fit within the bottom frame thus provided and rest upon the tops of the side and end rails. The burner box unit I1, shown in perspective in Fig. 45 4, is a completely enclosed unit and contains a drawer 26 mounted below a burner containing section indicated at 21.

The construction of the burner box unit is shown in Figs. 7 to 12. The body of the unit consists in the main of a bottom plate 28 of pressed sheet metal, a back wall 29, side walls 30,

a top rectangular frame 3| of structural angle iron, and a front cast rectangular frame 32.

These parts are so constructed and arranged as to greatly facilitate assembly and to produce a rigid, substantial structure of relatively light gage material, and this without the necessity for provision of a frame upon which the front, back and bottom walls may be fastened and supported.

The bottom wall 28 is depressed to provide a marginal raised horizontal flange 33, the shape of the depression being such that it fits nicely within the base frame of the stove, as will be later more fully described. The bottom is also provided with an upturned flange 34 at the front and rear which is perforated at 35 to receive fastening bolts or other devices.

The top frame consists of four angle irons welded together at their ends, the two side angle irons extending across the ends of the front and back angle irons. The horizontal flanges of all four angle irons are at the top, and those of the side angle irons extend outwardly and those of the front and back angle irons extend forwardly, as may be seen in Fig. 9.

The front cast frame 32 is provided with inset side and top flanges 36 at the opening. At the bottom three bolts 3'! are arranged for insertion through the openings 35 on the front flange 34 of the bottom plate to secure these parts together. Like bolts 31 are arranged to extend rearwardly from the top of the frame 32 and into companion openings in the front angle iron of the top frame, as may be seen in Fig. 8.

The back plate 29 consists of a single flat sheet of metal secured at 38 at the top and bottom to the rear face of the rear angle member of the top frame and to the inner face of the rear upturned flange of the bottom plate.

Each side plate 30 is provided with top, bottom, and rear inturned marginal flanges 39 adapted for engagement with the angle frame at the top, the marginal flange 33 at the bottom, and the adjacent edge of the plate 29. Companion openings 40 are arranged through the rear flange 39 and the adjacent edge of the back plate 29 to receive fastening bolts. At the front, each side plate 30 is provided with an offset vertical flange 4| adapted to be disposed within a continuous side flange 42 of the cast front frame 32, and in behind this flange are lugs 50 cast on the frame and adjacent to the side flanges 42. Thus constructed and assembled, the parts of the casing are all firmly locked together in a rigid sturdy construction. The side plates in the assembly have their top flanges 39 beneath the laterally extending flanges of the side angles of the top frame 3| and the bottom flanges of the side plates are arranged beneath the marginal parts 33 of the bottom plate. The dimension of the parts is such that the rear flanges of the side plates are disposed back of the edges of the back plate 29, the rear angle iron and back plate being cut away to permit this engagement.

Viewing Fig. 8 of the drawings, it will be noted that the unit is provided with a cast iron stove top Ma and a skeleton vessel supporting grate 42a of usual or preferred construction. A front wall of the burner compartment 43 is provided to flt within the top part of the cast iron frame. This wall is provided with inturned marginal top and side flanges 44 and two brackets 45 of stirrup form are spot welded to its inner face. One of these is located adjacent each end or side of the wall 43 and in position to engage a perforated boss 46 provided at each side of the cast front frame of the unit. A bolt 41 (Fig.

12) is arranged through the boss 46 and through the bracket to hold the wall 43 in position.

The manifold 48 for the burners is arranged within the unit and back of the wall 43. It enters the unit through an opening 49 at the rear and is disposed along one side wall and across the front of the stove, as may be observed in Fig. 7. It is held in position from the front cast frame, and to this end clamping members or arms 5| are cast integral with the frame and co-operate with companion clamping members 52 to hold the manifold in position. Burner valves 53 are arranged to extend up from the manifold and have gas outlets 54 adapted to be arranged in the mixing chambers 55 of burners 56. These burners are supported at the front upon the gas outlets 54 and at the rear upon brackets 51 of angle form which extend down from a fastening 58 from the top angle iron along in front of the back wall, and thence forwardly beneath the burner, as may be observed in Figs. '7 and 8. Openings 59 are provided in the wall 43 to permit the passage of valve manifold means 60.

The bottom of the burner compartment consists of a sliding shelf 6| arranged upon slideway members 62 of angle form which are arranged horizontally inwardly of the side walls of the stove and secured at their front and rear ends respectively, to the inset flange 36 and to the back plate. The drawer 26 is adapted to close the opening in the front frame beneath the shelf in the bottom of the burner box compartment and is mounted upon extension slides 63 arranged upon the top of the bottom plate parts 33 and beneath top guide members 64.

A table top is or may be provided for the burner box unit. This top, indicated at 65, is hinged at 5| along the rear of the stove. The table top consists or may consist of two metal sheets, the topmost one of which is flanged downwardly at 66 at the sides and front of the stove, and thence inwardly at 61 to provide a box-like edge. The top plate extends rearwardly through a slot 68 between the top of the back wall 29, back wall extension 30, and the lower edge of an apron 69 which extends up from the back of the stove. The rearward extension of the plate 65 is bent upwardly at and rearwardly at H to receive an arm 72 to which a counterbalancing spring 13 is connected. The spring 13 in turn is fastened to the back of the stove, as may be observed in Fig. 5, two such springs being provided.

The under sheet of the table top of the stove, indicated by reference character 14, is flanged to a box-like structure about its marginal edges to provide an air space within the table top to insulate its upper surface from the heat of the burners when the top is lowered after the burners have been in service.

The combined oven and broiler unit is similarly built and is provided with an upper oven section 8| and a lower broiler section 82 adapted to be closed by doors or drawer fronts as may be desired. The hand operated valve for controlling the oven burners is arranged through the front wall of the unit above the oven door or closure, as indicated at 83, and a thermostatic control is similarly arranged as indicated at 84. These controls extend through across the top of the oven and are connected into the piping back of the back wall of the stove as may be observed from Figs. 5 and 6.

Gas is supplied to the oven from the manifold supply pipe 48 which is connected in a well-known manner to the usual fuel main, through a pipe 85 bent to Z-form and connecting at one end to an elbow 86 at the manifold and at the other to an elbow 81 leading directly to the hand valve 83. A pipe 88 leads from the hand valve to the thermostatic valve 89 and from this valve down to an inlet pipe 9| leading in to the broiler and oven burners. A pilot light 92 extends down similarly.

The burner box unit and combined oven and broiler units just described may be reversely arranged upon the base and Figs. 3 and 4 show the manner of their positioning. One or the other of the units is first mounted upon the base, as may be observed in Fig. 3, and is pushed over until its depressed bottom engages the presented angle iron flange 23 of the base frame, whereupon the companion section may be arranged upon the base frame by merely lifting it and tilting it to insert its bottom depression likewise within the base frame. The Z-pipe may then be connected by the turning of two union nuts I0l to connect with the elbows 86 and 81, already described.

It will be manifest that the two main units, i. e., the burner box unit and the combined oven and broiler unit, may be arranged with either to the left or to the right as may be desired and that the entire assembly in either position may be accomplished without requiring access to the interior of the unit. That is, the doors and the drawers may remain closed during such assembly.

Referring to Fig. 13, a range is illustrated wherein the two parts of the stove are of coextensive height so that when the table top is lowered upon the burner box section an even and substantially unbroken surface is provided across the oven and the burner box, and this independent of which of the two major units is arranged at the right or the left of the assembly.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form' hereinbefore described being merely a preferred embodiment thereof.

I claim:

A range unit, comprising a bottom plate, a top frame, a front casting, and side and back walls, said front casting and rear wall each being secured to said bottom plate and said top frame, and each of said side walls being secured only to said rear wall and being-maintained in proper relation to said front casting by means of a vertical flange thereon engaging between a vertical flange and cast lugs on said front casting, whereby all of said parts are firmly locked together to form a rigid assembly.
