MICHAEL O. ARMOUR, OF CHICAGO, ILLINOIS.

STOVE.

SPECIFICATION forming part of Letters Patent No. 284,112, dated August 28,1883.

Application filed August 7, 1882. (No model.)

To all whom it may concern Be it known that I, IVIIGHAEL G. ARMOUR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stoves, which are set forth in the following specification, reference being made to the accompanying drawings, in which Figure 1 shows a stove embodying my improvements, the right-hand half being a front elevation and the left-hand half being in central longitudinal vertical section, the two halves thus shown being counterparts of each other. Fig. 2 is an end view of said stove, showing one of the lamps partially removed. Fig. 3 is a plan section taken 011 the line w m of Fig. 1 through the lamp-chamber and top of the combustion apparatus, and Fig. 4 is a plan view of the perforated covering-plate.

My invention relates more particularly to stoves which use oil or gas for, fuel, though some features are-also applicable to stoves in general.

The objects of my invention are, first, to provide a convenient mode of adjustment between the flues or chimneys of the removable lamp and the flue of the stove proper, into which said chimneys discharge the' combustion-current; second, to provide a stove with a sliding oven, adapted to cook by bringing the products of combustion in direct contact with the food; third, to provide for more thoroughly heating an oven through which the combustion-current passes; and, fourth, to provide for the more equal distribution of the products of combustion through exits not directly over the flame, and over which exits food may be cooked. v

In the drawings, A represents the lamp,

which is composed of a reservoir, wick-tubes,

air-box, cones, chimneys, 8nd, arranged in the usual way. The lamp is supported in the stove by means of the edges of its cone-plate B, which rest on slides 11, projecting from the sides of the lamp-chamber. The chimneys O are surmounted by a horizontal plate, I), provided with openings corresponding in position with the tops of the chimneys. This plate D forms the bottom of a chamber, E, interme diate between the chimneys and the horizontal flue F at the top of the stove. Three sides of this'intermediate chamber are formed by a flange, 6, depending from the floor of thehori zontal flue (which is cut away within this flange) and closely surrounding the back and sides of the plate D, on the front of which is mounted an upwardly-proj ecting flange, d, which forms the fourth side of the chamber. It will be seen that the lamp-chimneys thus make tight joints with the horizontal flue, without in the least detracting from the facility with which the lamp may be adjusted.

d are studs rising from the plate D, which are provided to enable the attendant to remove the combustion apparatus (composed of the lamp and chimneys, 850.) from the stove, and heat flat-irons, &c., on the top of this combustion apparatus without smothering the flame.

Between the two lamps is an oven, I, heated by radiation therefrom, this radiation be ing intensified by thehot air around the lamps being drawn into and through the oven I (through the perforations i and L) by induc- ,tion' produced by the combustion-current in its passage near the latter perforations. The oven I is thus in reality a part of an induction-flue, the lamp-chambers through the perforations z forming the feeding ends thereof.

The top of the flue F is composed of three removable coveringplates, H, the vertical walls of said flue being the four sides of the stove, near its top. The center one of these covering-plates is perforated and provided with ridgesor protnberances h, rising above the general level of the top of the stove, the

perforations h being in the depressions between said ridges. Thc other two coveringplates H are provided with vessel-openings and suitable covers, h", and rings 7L3 therefor. The three plates H all stand in substantially the same place.

G is an upper oven, the bottom of which is composed of a rack, g, the openings in which admit the products of combustion to all parts of this oven, the top of said oven being provided with suitable exit-openings, i", for said products of combustion. This oven G has guides or flanges 9, depending alongside the front and back of the stove-top. The alternate sides of this oven, however, (between the sides on which these guides are attached,) are slightly cut away at the bottom, in order to allow of the sliding of this oven over the ridges h. It will be seen that this oven G may thus, by sliding it, be readily adjusted, so as to be used directly over either lamp, or at any intermediate point, as desired.

In the drawings the oven is shown midway between the two lamps and directly over the perforated plate H; but this oven G can be warmed solely by radiated heat, when it is desired to appropriate the combustion-current otherwise, by simply sliding it over either lamp without removing any part of the closed covering-plate. It will be observed that this oven G, as well as the covering-plate under it, is heated not only by the combustioncurrent, but also by the induction-current. By setting in motion the heated air around the lamps toward the stove-top or oven G, where it can be utilized, less heat is radiated through the sides, of the stove.

It will be observed that the use of two lamps, (instead of one,) one at each end of the stove, when combined, as shown, with the center plate, H, is attended with the advantage that the combustion-current, inasmuch as it proceeds to the exit-openings of an intermediatelylocated covering-plate from opposite directions, is distributed more uniformly in its passage through said plate than would be the case if both lamps were consolidated into one lamp at one side only of said plate H. The perforations h, in whatever angle to the stove the former may be set, always, even when the protuberances are all covered by a cooking utensil, furnishing at least side exits to the outer air, which admit of the escape and consequent continuity of the combustion-current, while at the,

, sure almost uniformly the attainment of these beneficial results.

All this may be accomplished, while at the same time the combustioncurrent thoroughly heats each end of the stovetop, by direct contact with its under side before the currents thus unite at the center plate, II. In this way the whole stove-top is made wholly and equally available for cooking purposes, the disadvantage arising from the center plate being farther from the flame and receiving the combustion current after its heat has been partly exhausted by radiation being compensated for by the union of two currents and their uniform distribution directly upon and around the food or utensil \resting upon or above the perforated plate,

(whether in connection with the oven G or not,) and thus placed in immediate contact with and thoroughly enveloped by said current.

The advantage of heating a combustion-eurrent oven, when used in connection with apart of the stove-top reserved for cooking purposes, by two combustion apparatuses, one at each side, instead of one combustion apparatus at one side, is that the heat is thereby more evenly distributed through said oven; and the draft through the same is improved by reason of the diminution of the distance between the entrance and exit of a given current, which, by the present construction, isrendered compatible, with a thorough permeation of said oven by said combustion-currents.

I do not claim, broadly, a stove having a combustion apparatus at each end and an orifice in the top between said combustion appa ratuses, and accessible to the currents from the same, but not intended for their exit; and I do not here claim the cOVering plateshOWn by Fig. 4.; but

\Vhat I claim as my invention, and wish to secure by Letters Patent, is
