COOKING STOVE OR RANGE.

SPECIFCATION forming part of Letters Batent No. 693,343, dated February l1, 1902. Application filed December 13, 1900. Serial No. 39,687. (No model.)

To all w/tom 'it may concern:

Be it known that I, EDGAR W. ANTHONY, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Cooking Stoves or Ranges, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part 1o of this specification, in explaining its nature.

Figure l is a view in vertical section of a' range havingthe features of my invention.

upon the dotted line l l of Fig. 2, also showzo ing in elevation the parts of the range back 3o ranges.

4o right angle to the Walls.

of said line. Fig. 2 is a vewof the range in cross-section upon the dotted line 2 2 of Fig. l. Fig. 3 is a view of the range in horizontal section upon the dotted Yline 4 Al of Fig. l. Figs. 4, 5, and 6 represent the hearth-plate and its riln or band.

The cooking stove or range has the ash-pit A,the fire-pot B, and` ordinary dues cornmon to the usual types of cooking stoves or The bottom, top, and side walls of the baking-oven O are made of sheet metal, preferably in one piece. This produces a box-like structure open at both ends. It is attached to the stove or range in the following manner: One end is riveted to the flange c of the oven-door frame c,the door-framebeing itself bolted or riveted in place to the side plate of the range. vThe inner end of the side walls has lugs or ears c2, which extend at a These lugs or ears preferably are of cast-iron and formed integral with the plates O O2, hereinafter referred to. The lugs or ears have holes through which are bolts or screws c3, extending through the side plate o* of the stove. The side plate c is formed, as represented in Fig. 3, to provide a shallow chamber c5 on its inner side, having the inclined or tapering edge or wall c6. The inner end of the sheet-metal walls is a little larger in size than the inner end of `not rust or tarnish under any condition.

The bolts or screws' engaging the lugs or ears serve when tightened to draw toward the side plate o4 of the stove and into the shallow chamber the inner corners of the oven-walls against the inclined wall c ofthe 'side plate, causing thc corners of the oven-walls to conform to and tightly hug or bear against the inclined wall to such an extent as to make a sufficiently tight joint between the inner edge of the oven-walls and the side plate ol' the stove. The door-frame c' is at the same time drawn by the screws or bolts c3 to its seat against the side frame ofthe range. The lugs or ears c2 serve to receive the oven end plate D and to hold it separated from the side plate c4' sufficiently to create a dead air space c7 between it and the side plate. The side platelnay also be lined orcovered upon its inside with a sheet or layer of asbestos paper cl or other non-heat-conducting material, and the dead-air space c and heatdeadening 'layer prevent conduction of heat from the oven through the side plate of the stove. The metal plate D, which forms the inner end of the'oven, is fastened at one end by the lugs d, extending from the plate, and at the other end by a tap-screw d2, which screws into one of the ears or lugs c2. This end plate D preferably has its out or exposed sidelined or surfaced with porcelain or similar material to provide a whitepolished illuminating-surface to reflect forward the heat of the ovenin the oven-chamber and to disseminate and reect inthe oven-chamber the light striking against it when the oven-door is open, so that the backpart of the oven is made attractive and visible and the end provided with a clean white finish which will The plates O C2 are cast-metal plates andare riveted or otherwise attached to the sheet-metal walls ot' the oven, and they are provided with ears or ledges for supporting an oven-shelf.

The plate O is also a fine-forming plate, and

it is attached by its outer end to the flanges cand o8 of the oven-door frame c. (See Fig. 2.)

Between the side wall e of the oven and the rear wall e of the ash-pit there is an air-flue IOO ing through the bottom of the range. (See l `igs. l and 3.) The said air-flue E is connected, by means of holes ein the side wall e, with an air-circulating flue or passage el within the oven, formed by the castanetalplate C'. 'lhis plate C is of an angular shape-that is, it is formed to cover a large section of the side wall and of the top of the oven-and it is connected with the oven by the opening e5 along its lower edge, and it opens into the oven by an outlet e at its rear end. The plate is further fashioned to provide an enlargement e7 of the line or passage e* by being bowed outward into the oven, and this bowed portion of the plate covers a considerable part of the upper central area of the side wall e. This increases the width of the (lue or passage against the portion of the wall of the oven which is most liable to become overheated and provides a larger air circulation against this portion of the wall, and thus tends to prevent the overheating ot the plate e from overheating the oven. The operation of this part of the invention is as follows: Airis drawn into the iiue E through inlets and passes into the oven circulating ilue or passage c" and through this passage about one side and a larger portion of the top of the oven to the on tiet e, where it enters the oven. As the ilue or passage e4 also has an inlet el from the oven, it follows that the circulation it provides not only supplies `the oven with fresh air of uniform temperature, but also establishes a circulation through the oven by causing air to be drawn from the oven through the inlet e5 and to be mixed with the atmospheric airas it enters and passes through the flue el. The flue e4 establishes an airspace at the side of the oven toward the [ire-pot and. at the top of the oven, which serves, in addition to its functions as a source of supply of fresh air to the oven as a circulating agent, to prevent the overheating of the oven by checking the conduction of heat from the side wall and top of the oven. The castmetal plate C may have one or more small holes e* opposite the inlet-holes e3 through the flue e4, through which air from the oven may enter the passage, and there may also be one or more vent-holes e in the back plate opening into the back flue.

I have shown in Fig. 2 a shelf construction comprising a shelf F, having an extension which is therein indicated in dotted and full lines. This construction I do not describe in this application, as it forms part of my application for Letters Patent of the United States, Serial No. 72,867, filed August 22, 1901.

I have shown in Figs. 4, 5, and 6 a construction of a band or rim which, while as shown it is applied to a hearth, may be applied to a stove-plate or other like portion of a stove. I will describe it here, however, as applied to a hearthband for purposes of convenience merely. lleretofore hearth-bands have been made in two parts, which abut at or near the front corner oi' the hearth andform a straight joint, indicating at once that the band or rim had been formed of two pieces. This is ob jeetionable because of this appearance and because the joint collects dust and other inatter. 3y my improvement, while the l1earth band is still made in two pieces, it has the appearance of being continuous or in one piece.

"This result is obtained by causing the corner end 7i of one section Il to be shaped alongits outer end and to have its top adjacent to said end so formed as to provide a portion of a design 7L and also by fashioning the abuttingend h2 of the other section H of the band to form a part of the entire design, the edge of which section H', with the edge of the corner h, constituting a line 71.3 of the design. The said end of the second section may servo to secure the corner of the first section in place to the stove by being shaped to form a stinken recess or support under which a lip h4 may extend or lap.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a cooking stove or range, a side plate having a shallow chamber upon its inner side provided with inclined walls with a sheetmetal oven having a bottom, top and sides and open at its back, slightly larger than the inner end of said chamber and of a shape to lit into the same, and connections between said side plate and the oven for drawing the sheet-metal oven into said chamber until its inner edge or portions thereof are brought into close contact with the inclined walls of the chamber, as and for the purposes set forth.

2.
