GAS-STO V E.

SPECIFICATION forming part of Letters Patent No. 448,579, dated March 17, 1891.

Application filed August 20, 1890. Serial No. 362,467. (No model.)

To aZZ whom it may concern: and downwardly flaring in shape. This down- Be it known that I, CHARLES H. EVANS, a wardly-flaring arrangement of the perforacitizen of the United States, residing at J acktions greatly accelerates the draft and causes son, in the county of Jackson and State of the air to pass to the burners, situated below 5 Michigan, have invented certain new and usesuch foraminated plate, in sufficient quantity ful Improvements in Gas-Stoves; and I do to insure a complete combustion of the fuelhereby declare the following to be a full, clear, gas, and I have devised such further details and exact description of the invention, such and combination of parts as will be hereinas will enable others skilled in the art to after pointed out and covered in the claims. IO which it appertains to make and use the I will now proceed to give a detailed desame. scription of myinvention, reference being had Myinvention relates especially to that class to the accompanying drawings, in which of gas-stoves in which fuel-gas, or what is Figure 1 represents a vertical section of known as water-gas, is burned. a stove embodying my invention; Fig. 2, a r 5 The object of my invention is to provide a sectional plan of the same; Fig. 3, vertical gasstove in which the same burner or burnsection taken on a plane at right angles to ers will serve to heat both a broiler and an that of Fig. 1.

I accomplish this bodying my invention.

It is in the features now to be tie the carbonic oxide contained in the fuel-gas, scribed that my invention relates. inasmuch as the accumulation of that gas in In the upper part of the broiling-oven D a room may prove dangerous to life. I have are located the burners h, and above them is attained this object by providing, preferably, arranged a foraminated reflecting-plate .I, too

as best shown in Fig. 6. By this arrangement of the forarninated plate I am enabled not only to throw sufficient heat downward into the broiling-chamber, but also to utilize the waste heat by carrying the products of combustion through the perforations and upward around the oven C. By the conical shape of the perforations I am enabled, moreover, to produce a far greater draft of air through the same, the air being sucked into them with a much greater force than if the perforations were cylindrical in shape. I am thus enabled to produce the requisite circulation of air to or around the burners to insure a complete combustion of thefuel-gas employed.

The burner-frame ll consists of a main conduit G, from which run a number of parallel tubes 71, closed at their ends and having perforations 7t, preferably at their sides. This burner-frame If, it will be seen, may be readily slipped into the stove-easing, which is provided with perforations at the proper point for the insertion of these tubes as also the broiling-oven I). When the burner-tubes h are inserted into the stove to the full extent, their ends preferably rest upon a ledge t', attached to the interior of the broiler opposite the perforations in the stovecasing above referred to. The tubes h are preferably screwed into the main conduit G, and the latter is connected to the permanent gas-pipe e by a union is, best shown in Figs. 2 and 7.

When it is desired to remove the burnerframe If from the stove, all that is necessary is to uncouple the pipe 6 and the main conduit G by turning the union it, when the entire frame may be withdrawn from the stove for the purposes of cleaning or repair, the gas-pipe 0 having been shut off by turning the cockf.

In Figs. t and 5 I have shown a modification of a stove embodying my invention,and wherein the oven 0 has been entirely omitted, and the broiling-oven L may be here utilized as a baking-oven, the ledges which are shown serving to support shelves when required for such purposes. I have also omitted the pot-lids, but have provided perforations l\' in the sides of the chamber M, adjacent to the broiler L and above the foraminated plate J, for the escape of the products of combustion. The top of this last-described stove or broiler is covered with a smooth polished plate m, of cast-iron or other suitable material, upon which griddle-cakes or the like may be baked and the waste heat of the products of combustion passing through the chamber M from the broiler utilized. I thus produce a combined broiler or toaster and cake-baker heated by one and the same burner or burners.

I have shown the foraminated plate, oven, or chamber M and burners 7b as located above the broilii'ig-chamber L; but it is evident that their location might be modified in various ways. All that is necessary is that the supplemental chamber to be heated by the waste heat be adjacent to the broiler and that the foraniinated plate be located between the two and adjacent to the burners, so as to reflect their heat into the broiler. Still I prefer the construction as shown. It is also apparent that the devices herein described and shown may be modified in many details without departing from the nature of my invention,and I therefore do not desire to limit myself to the exact details shown and described; but

What I claim, and desire to secure by Let ters Patent, is

1. In a gas-stove, the combination with a broiling-oven and burners located within the same, of a chamber adjacent to the broilingoven and a foraminated reflecting-plate adjacent to the burners and between the broiler and the adjacent chamber and extending entirely across the broiler, substantially as and for the purposes set forth.

2. In a gas stove, the combination of a burner or burners with a partition having conical perforations flaring toward the burner or burners, said partition being arranged over the burners and extending entirely acrossthe interior of the stove, substantially as and for the purposes set forth.

In a gas Steve, the combination of a broiling-oven and burners located within the same with a foraminated upper wall located above the burners, extending entirely across the broiling-oven and beneath the heatingchamber above and having conical downwardly flaring perforations, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
