This invention relates to stove doors, and has to do particularly with the oven and broiler doors of gas and vapor ranges.

, In recent years, stove ranges of the better class have been so fabricated and finished that all of the exposed surfaces have been enameled. As a result of this practice,.practically all of the better class stove ranges on the market present a very pleasing appear anoe and at the same time are very sanitary in that substantially all surfaces may be easily cleaned and because of such enameled surfaces, all grease and other foreign matter may be readily seen.

As the general appearance of an enameled range depends to a large extent upon the design and fabrication of the doors, considerable attention has been paid to the forming and enameling of the stove doors and heretofore it has been thegeneral practice, in the better stoves, to form oven and broiler doors of cast iron so as to accentuate the various lines and features of the particular design embodied in the stove as a whole. However, such cast iron and enameled doors have not only been expensive to manufacture but have had their limitations in ornamental design.

It is the object of the present invention to provide a pressed metal oven door which retains all of the better features and qualities of the cast iron door but which presents a door much easier to fabricate and enamel and which makes possible the forming of a completely different type of ornamental door. This new result is obtained by so fabricating the sheet metal door panel to present one or more embossed frames, said embossed frames providing suitable recesses for receiving completely separate panels to complete the formation of the stove door. The stove door itself is fabricated in a novel manner both as to the formation of the front panel and the back panel.

In the drawings, 1 is a perspective unit of a stove range provided with doors embodying the present invention.

It, will be understood that the door structure of the present invention maybe embodied in substantially any type of range, and in Fig. 1 I have illustrated a range of the standard type and the design of the novel doors is shown so as to fit in with this general'standard design.

The stove doors for such oven and broiler openings are fabricated by first stamping out a sheet metal frame to define the front of the doors. A portion of such sheet metal frame completely stamped out is shown as 'at 3 in Fig. 3, and in stamping out this sheet'rnetal frame an outer moulding or embossed portion 4 is formed to extend completely around and define the outer edges of the door. A second molding or embossed portion 5 may be formed similarly to the portion 4 but spaced inwardly therefrom.

Spaced between the embossed frame 4 and the embossed frame 5 is a depressions and defined by the embossed frame 5 is a central depression which may be generally designated 7 The bottom edge of each door is preferably curved over as indicated at 8 in Fig. 6 whereby to receive a suitable hinge and spring structure and the sides and top of each door are preferably curved inwardly as at 9 and 10 respectively.

The depressions 6 and Z formed by the embossed panels 4 and 5 may of course take any desired shape and design in accordance with the particular stove with which they are to be used, the main point being that certain embossed frames are formed or pressed out from sheet metal to form a portion of the exposed surface of each door.

In the embodiment shown in the drawings an insert panel 11 is provided, which is perfectly rectangular in shape so as to correspond with and fit in the depression 6 formed between the embossed frames 4 and 5. This insert panel 11 is preferably provided with inturned lugs or projections 12 as best shown in Fig. 2, whereby when the panel is inserted in the depression 6 it will present a well defined outline as well as a very solid appearance. Said lug members 12 also assist in firmly seating the panel in the depression.

In order to permit quick assembly of the inserted panel 11, I preferably provide suitable apertures 13 spaced around the depression 6 and I also preferably secure a plurality of threaded bolts 14 to the back of the panel 11. These bolts 14 are preferably secured to such panel by spot-welding the same thereto. With the spot-welded bolts or studs 14 in position on the panel 11 it will be obvious that as a panel is placed in position in depression 6 that such bolts will protrude through the apertures 13 in order to receive suitable nuts 15 for rigidly securing the panel in place.

In order to compare favorably with the cast iron door and also to cover up the front panel of each door, I provide a back panel which may be generally designated 16. This panel 16 is preferably formed from sheet metal and consists of the dished out portion 17 and inturned peripherial flange 18, such flange 18 contacting with the inner surface of the flange 4, as best shown in Figs. 2 and 5. To permit quick assembly of the front frame 3 and the rear panel 16 I preferably provide corner members 20 which may be positioned either at the lower corners of each door or at all the corners of each door.

These lower corner members are preferably shaped as shown in Fig. 4 and in case the upper corner members are used they are preferably shaped as also best shown in Fig. 4. Each corner member 20 is preferably provided with an aperture 21 which is designed to register with an aperture 22 in the panel member 16. The flange 18 of the back panel member is preferably recessed or cut away adjacent each corner of the door whereby to receive a corner member 20 and this corner member 20 is preferably flanged as at 23 to form a channel member, the back of which contacts with the inner surface of the embossed frame 4, at the corners.

This channel member 23 may be spot-welded to the inner surface of the frame 4 or one lug 24 of such channel may extend upwardly to contact with the grooved in portion or portions of the front door frame. I also provide an L shaped lug 25, having a threaded hole 26, and this lug 25 is adapted to be fitted into the triangular space defined by corner member 20 and the sloping surface of the depression 6.

In assembling the front and back panels of the door it will thus be obvious that I only have to insert the L shaped lug members 25 into position behind the corner members 20. which may be positioned in each corner of the door and then place the back member 16 in place, after which suitable screws 27 may be inserted through the apertures 22 to engage the threaded holes 26 to bring the front panel 3 and back panel 16 rigidly and seicurely together.

In the construction of my door members, I preferably subject the embossed frame members 4 and 5 to a nickel plating or chrome plating action. such embossed frame members making this plating step very convenient. The panel member 11 and the inner panel member 28, which is preferably identical in general fabrication as the panel 11., are subjected to the usual enamelmg steps whereby to receive a smooth finished coat of enamel. To assemble the outer door frame before complete assembly of the door it is then only necessary to insert the desired panels 11 and 28, with their spot-welded studs, into position on the door frame and then secure such panels in position. It will thus be obvious that any number of door frames 3 may be fabricated with the nickel or chrome plated frames 4 and 5 and that any number of different color combinations of panels 11 and 28 may then be inserted in the depressions 6 and 7 to complete the door assembly.

In connection with the depression 7, I preferably form suitable pressed-out portions 29 therein whereby to materially reinforce this central part of the front door frame. It will be obvious that the broiler door and even other parts of the stove may be fabricated and assembled in a manner similar to the oven door, the construction of which is shown in detail. These various doors or other parts of the stove are first fabricated to provide embossed or pressedout frame members which may be nickel or chromium-plated, and it will be seen that any number of different insert panels may be enameled with different colors or different color-combinations and kept on hand as an available stock supply. whereby a large number of different combinations may be obtained. In other words. while the main exposed surfaces of the stove may be of white porcelain enamel and nickel or chromium or any other color, the door panels and other parts which may be separately insertable may be of various other color combinatlons to complete the design and color scheme of the entire stove.
