2 Claims. (prize-39) This invention relates to stove and range structures, either gas or electric, and among the chief objects of the invention are: to simplify and improve the structure of such articles, to reduce their cost of manufacture and consequently their cost to users, to substantially reduce their weight as compared with known stoves and ranges, to provide a simplified and improved frame and body structure and top, to provide a structure that avoids danger of chipping or scratching the enamel on the upper edges of the side and front walls, to provide improved re-' movable burner grids and grid supports, and. generally to provide a multiple burner modern cabinet type stove or range of neat and trim appearance and that can be easily cleaned.

An illustrative embodiment of the invention is shown in the accompanying drawing, in which- Fig. l is a perspective elevation of the stove, showing the lids whichform a table top when the stove is not in use partly raised.

Figs. 2 and 3 are respectively top plan views of rectangular angle-iron horizontal top and bottom frame members that form important novel parts of the stove assembly.

Fig. 4 'is an enlarged vertical section taken on the line 4-4 of Fig. 1.

Fig. 5 is an enlarged vertical section through the side wall and wall supporting skirt or leg opposite that appearing in Fig. 1, showing the attachment of both the wall and skirt to the lower horizontal frame member and the location of the floor of the broiler chamber.

Fig. 6 is an enlarged vertical section taken on the line 6-6 of Fig. 1, showing the joint formed by the rear portion of one of the stove side walls, the upper horizontal frame member, and an end wall of the usual splash board at the rear of the stove top.

Fig. 7 is a perspective view showing the rounded corner formation of the horizontal frames,

the front and side members of which are bent to shape'from a single length of angle-iron.

Fig. 8 is a vertical section taken on the line 8-8 of Fig. 2.

Fig. 9 is a vertical side-to-side section through the stove top, taken on the line 99 of Fig. 1.

Referring to the drawing, l designates as an entirety a supporting base or leg of the short skirt type, consisting of a rectangular frame made of channel bars vl i, with the lower flange 92 (Fig. resting on the floor. Supported on the upper flanges 13 of the leg II are the inwardly extending horizontal limbs I 4 of the front and side members of a bottom rectangular horizontal angle-iron frame designated as an enpartment that has a downwardly bent and laterally offset extension l9 entered between the flange l3 of the leg H and the limb Id of the angle-iron frame l5; said broiler floor being' also attached. by a screw bolt 20 to a horizontal flange 2| on the lower edge of the inner lining of the wall I 1. Screw bolts 22 extend through and unite the relatively superposed elements 16, Hi, I9 and I3.

23 designates as an entirety, a top, rectangular horizontal angle-iron frame shown in top plan view in Fig. 2. The two end members of the frame 23 rest upon and are bolted to inwardly extending top flanges on the walls ll, whereby the top frame is mainly supported by and from the walls I].

It will be observed that the vertical limbs of the side and front members of the top frame 23 extend upwardly; while the vertical limbs of the side and front members of the bottom frame l5 extend downwardly. The side limbs of the top frame 23 are connected together somewhat inwardly of their rear ends by an angle bar 24, the vertical limb of which extends downwardly,

asshown in Fig. 8; and the side limbs of the bottom frame I5 are similarly connected inwardly of their rear ends by a bar 25, the vertical limb of which extends upwardly.

The portions of the side limbs of the frames l5 and 23 that extend beyond the bars 24 and 25 serve as frame supports for the customary narrow rear chamber of the stove that contains and mounts instruments of varying kinds, with which the present invention is not concerned; this rear chamber extending above the stove top in the form of a splash board or fence designated as an entirety by 26, this splash .board being equipped with end walls 21 that, as shown in Fig. 6, are formed with inwardly offset horizontal flanges 28 that rest upon and are bolted to the rear extensions of the side members of the top frame 23.

Fig. 7 illustrates how the front and side members of the frames 23 and ii are preferably fabricated from a single straight length of angleiron. At points opposite the front corners of each frame, the metal of the inwardly extending horizontal limb of the angle-iron is cut away from the vertical limb, and the bar is bent to rounded form as shown at 29, which causes the corners of the horizontal limbs to meet and contact each other. Since, as shown in Fig. 7, the horizontal limb is somewhat wider than the vertical limb, these meeting corners are mitered to permit'a rectangular bend, the meeting mitered corners being indicated at 30 in Fig. 7.

The front member of the top frame 23 and the rear member 24 thereof are rigidly connected and spaced by a pair of parallel cross bars 3| preferably of inverted. channel shape and buttwelded at their ends to the horizontal limbs of the frame bars, as clearly shown in Fig. 8. The top surfaces of these cross bars 3| are flush with the horizontal limbs of the angle frame bars as also shown in Fig. 8.

32 designates the usual upper front panel through which extend the usual gas burner knobs 33, and the panel 32, as shown in Fig. 4, is formed on its upper edge with an inwardly extendinghorizontal flange 34 that is secured to and beneath the horizontal limb of the front top frame member by screw bolts 35. 32 are the usual doors or panels-36, 31, 38, and 39 of the ovens and storage compartments. The storage compartments are, of course, equipped with suitable supports and guides for the drawers and the oven and broiler are similarly equipped with racks and slideways for baking and broiling utensils; but since the present invention is not concerned with these features of the stove, illustration thereof is not deemed necessary.

It will be observed by reference to Fig. 1 that the vertical edges of the side wall panels I! are rounded as shown at IT, so that their upper and lcwer'ends register with the rounded corners 29 of the top and bottom frame members 23 and I i5, which affords a neat and trim appearance encircle the. burners 43 slightly above the latter.

The removable burner. grid consists of a ring 45 shaped to fit and seat within the upper portion of the circular flange 44, and radial fingers 46 attached to and crosswise of the ring 45. The

rear portions of the fingers 46 rest on the plate 40, while their remaining portions overhang the Beneath the panel opening 42 above the burner. Heretofore, so far as I am aware, it is customary to form the grid and the grid ,7 supporting plate as an integral casting. My present construction is both lighter and cheaper to make, and enables either the grid or the grid and its-supporting plate to be removed when necessary to clean the burner or the usual plate underlying the burner.

In Fig. 1 I show the customary burner lids 41 that arehinged'at their rear edges to the rear member 24 of the top frame 23. r

In this cabinet type of stove, the parts making up the side and front walls are usually enameled, the enamel also extending over the top edges. It frequently happens that the housewife or cook, when removing a cooking utensil such as a fry- .ing pan, kettle, or the like, from the stove top drags it across the top edge and thereby chips,

scratches or otherwise mars the enamel finish,

which creates an unsightly appearance. By emplaying for this top edge the angle-iron frame 23, this marring of the enamel finish on the top edge of the stove is entirely avoided, the frame 23 customarily having a black lacquer finish. This is a substantial improvement in'this, type of stove and constitutes an important feature of the present invention.

From the foregoing it will be-seen that the described stove structure consists mainly of the horizontal top and bottom angle-iron frames 23 and I5, and vertical sheet metal walls and panels that are attached to the horizontal limbs of said frames. This affords a relatively/light construction which at the same time is very strong and rigid.

Variations and modifications in the structural details shown and described. may be resorted to within the spirit and coverage of the claims.

I claim:

1. In a stove structure of the class described, a rectangular horizontal frame member made from a single length of solid angle-iron having portions of its horizontal limb cut away on lines substantially at right angles to its vertical limb and having the portions of its vertical limb opposite said cut away portions bent to form rounded corners coextensive with said cut away portions.

2. In a stove structure of the class described, a rectangular horizontal framemember made from a single length of solid angle iron having its horizontallimb-wider than its vertical limb and rectangular portions of its horizontal limb cut away and the spaced ends formed thereby mitered at their comers, and further having the portions of its vertical limb opposite said cut away portions bent to form rounded corners coextensive with said cut away portions with said mitered corners in meeting contact with each other.
