GAS-RANGE.

SPECIFICATION forming' part of Letters Patent No. 722,414, dated March 10, 1903.

Application ned July 18,1901.

To all whom it may concern,.-

Beit known that I, GEORGE A. SIMPSON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of 5 Pennsylvania, have invented certain new and useful Improvements in Gas-Ranges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a new and improved gas cooking stove or range; and to this end my invention consists of a new and improved cooking stove or range, of new and improved means for heating the oven whereby the Walls thereof are uniformly heated, in a new arrangement of the oven burner or burners whereby the intense heat heretofore generated in gas-ranges directly over the door isdone away with, in a new and efficient flue system, and in the construction and combination of parts, all as hereinafter describedV and claimed.

In the accompanying drawings, which illustrate an application of my invention, Figure l is a perspective view of a range, showing a part of the front broken away to show the location of a burner and a portion of the oven. Fig. 2 is a vertical sectional view of the range, showing an oven-burnerin side eleration; and Fig. 3 a central vertical sectional view taken at right angles to the view of Fig. 2.

Referring to the drawings, the casing or stove-body comprises the front l, provided with a door 2, sides 3, and back 4, all preferably supported on a base-plate 5. As illustrated, the interior of the stove or range is divided into an oven 6, a broiler-space 7, in which is a burner 7 a space 8 for the upper burners 8*, and the flues or passages, all as hereinafter described.

The oven comprises the top plate 9, the bottom plate lO, the back plate 10, and the perforated side plates 11. Located between the side walls 3 and the side plates 11 are detlecting-plates 12, one on each side of the oven, and between said deecting-plates and the sides of the body I arrange the oven- For the purpose of admitting fresh air to the burners 13 the base-plate is Serial No. 68,814. (No model.)

I preferably provided with a series of openings 14.

A characteristic and important feature of the present invention is the means shown for producing an efficient and uniform heat throughout the interior of the oven. Heretofore, so far as I am aware, the oven of a gas-range has always been heated from a burner or burners located directly under the bottom plate of the oven, and consequently it has been impossible to heat the oven uniformly. By the construction shown I am enabled to cause the heated air and products of combustion to travel upward from the side burners through passages 15 over the tops of the deIiecting-plates and into the interior of the oven through openings 16 of the 'side plates 11, down through the oven to a flue or passage 17, located under the oven, and from thence to a flue 18 at the back of the oven. The course of the heated air and products of combustion is. clearly indicated by the arrows. I have shown the due or passage 17 having its top formed by the bottom plate 10 of the oven and the line or passage to the rear of the oven utilizing the back plate 10a of the oven for one wall of the said passage. However, instead of employing this construction-namely, utilizing the bottom and back oven plates for walls of said passages 17 and l8-separate and independ-` ent plates could be employed for the same purpose. In other words, if found desirable these lues could be formed separately from the oven and led under the bottom thereof and also up the back. Theinner face of the door 2 is employed for the front of the oven and directs the passage of the heated air and products of combustion into the flue 17, as particularly shown by Fig. 2. The back flue 18 continues upwardly above the oven and is in communication with the broiler-chamber 7 by openings 19 and with the upper burnerspace 8 by the openings 20. 'lhis Hue connects with the chimney-flue (not shown) in the usual manner. Rack-holders 21 are preferably placed directly above the openings in the side plates of the oven, and said openings are arranged to properly distribute the heated air entering the oven therethrough.

The advantages obtained from the forni of gas cooking stove or range, as illustrated and described, will be evident to those skilled in the art to which this invention relates; but I desire to particularly call attention to the uniform heating of the interior, top, front, bottom, back, and sides of the oven; also, to the arrangement of the oven-burners Wherebythe liability of the floor on which the stove stands catching fire, as is sometimes the case under the method of manufacture of gasranges as heretofore followed, lis done away with; further, to the new and improved flue system employed; also, to the fact that the burners are not located directly under the bottom plate of the oven, and consequently the iames from the burners are not brought in contact therewith, thus removing the liability of burning the articles placed in the lower part of the oven and also prolonging the' life of said plate.

Having thus described my invention, what I claim is l l. In a gas stove or range, the combination, with a casing, of an oven, a fine at the side of the oven within the casing, a combustionchamber in said ue, a burner in the combustion-chamber, a defiecting-plate between the burner and side Wall of the oven, openings in the side Wall, a flue or passage Linder the oven into which the heated air and products of combustion pass after their travel through the interior of the oven for the purpose of heating the bottom of the oven, and a flue or passage back of the oven in communication with the iiue or passage under the oven, substantially as sot forth.

2. In a gas stove or range, the combination, with a casing, of an oven having a perforated side Wall and an imperforated top and bottom, a burner and a combustion-chamber in a flue at the side of the oven, a flue or passage under the oven of substantially the same Width and depth as the oven and independent of the combustion-chamber, into which the heated air and products of combustion pass after their travel through the interior of the oven, and a back flue or passage in communication with the flue or passage under the oven, substantially as set forth.

3. In a gas stove or range, the combination, with a casing, of an oven, a flue at the side of the oven Within the casing, a combustionchamber in said flue, a burner in the combustion-chamber above the bottom plate of the stove, openings in a side wall of the oven for the' passage of heated air and products of combustion from the combustion-chamber into the interior of the oven, a flue or passage independent of the combustion-chamber under the oven, and a flue or passage at the back of the oven in communication with the iiue orpassage under the oven whereby the heated air and products of combustion have-a continuous travel from the combustion-chamber to the back flue or passage by way of the interior of the oven and the iue or passage under the oven, substantially as set forth.

4. In a gas cooking stove or range, the combination, with a' casing, of an oven having openings in the side walls thereof, a burner located at each side-of the oven, and arranged over openings for air, and a deflecting-plate between each burner and the side walls of the oven, substantially as set forth.

5. In a gas cooking stove or range, the comb'ination, with a casing, of an oven, a ue at the side of the oven, a burner therein, openings in a side Wall of the oven for the passage of heated air and products of combustion from the side flue to the interior of the oven, a flue or passage under the oven, a back flue or passage in communication with the flue or passage under the oven, a broiler-chamber having a burner therein above the oven and in communication with the back fine or passage, substantially as set forth'.

6. In a gas cooking stove or range, the combination, with a casing, of an oven, a ue at the side of the oven, a burner in said side ue, openings in a side wall of the oven for the passage of heated air and products of combustion from the side flue to the interior of the oven, a flue or passage under the oven, a back iiue or passage in communication with the flue or passage under the oven, a burnerchamber above the oven in communication with the back Hue, and a burner in said chamber, substantially as set forth.

In testimony whereof I aix my signature in presence of tWo witnesses.
