COOKlNG-STOVE.

SIPEC'JIFIGATICH forming part of Letters Patent No. 898,790, dated February 26, 1889.

Application filed February 9, 1888. $erial No. 263,545. (No inodelfl Be it known that we, JOHN LR] lllih idlc'li and \VTLLARD .T. Awnnuws, ciiizens oi the United States, and residents of the citv oli' St. Louis, in the State of Missouri, have invented certain new and useful lii'nprovements in Damper Systems for Cooking-Stoves, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which our invention apperiains to make and use the 821110, reference being had to the accompanying drawii The object of this invent i011 is to provide a system 01' dampers for cooking-stoves so located and arranged that by opening and closing certain of them, singly or collectively, the heat of the fire ma be conveyed, first, beneath half the stove-top; second, beneath v the entire stove-top; third, beneath half the stove-top and around an upper oven; fourth, beneath the entire stove-top and around an upper oven; fifth, beneath half the stove-top, around the lower oven, and beneath an upper oven, and, sixth, beneath the entire stove top, around a lower oven, and hen eath an up per oven. This object we accomplish by i means of the devices described in the following specification, which we consider the best means of carryin out our invention. It will be seen that the man 5* directions in which we 1 may carry the heat from the tire to the chim ney will give rise to variable degrees of said heat without the need oi. any special form of draft-d ampers either in the ash-pit or sniokeflue, or without, in fact, requiring that such draft-dampers be operated at allthat to i say, in case one, above, where the heat passes v directly from the fire beneath half the stovci top to the smoke flue or chimney, there will of course be more intense heat for cooking purposes than in case two, where the same i beat is distributed over twice the area, and the same rule will hold good throughout the 1 other cases.

In the drawings hereto attached, and forming a part of this specification, Figure l is a general front elevation of our stove with a warming-rack mounted thereon. Fig. 2 is a central vertical transverse section of said stove on line 2 2 of Fig. Fig. 3 is a plan To all whom it may concern: l

i l i of the stove, taken on line 3 3 of Fig. 2, just i beneath the stove-top. Fig. t is a plan view on the line i i of Fig. 2, just beneath the upper oven and grate. l ig. 5 is a vertical section on the line i 5 ol' i ig. 2 through the fire-pot and ash-pit, looking toward the ovens. Fig. 6 is a vertical section on the line 6 (i of Fig. 2 through the ovens and exit-fine; and Fig. '7

. is a vertical section on the line 7 7 of Fig. 2

through the side flue, looking toward the ovens, part of the exit-flue being broken away.

Similar letters and numerals of reference indicate similar parts in the several figures.

It will be understood that our improved damper system may be applied to any stove other than that illustrated and described by conforming its arrangement thereto without departing from the spiritof our invention; also, that any suit-aide and serviceable form of damper may be used other than thatshown,

which, however, we prefer.

In the present instance the ash-pit is arranged at the left, with the fire-pot above and grate l)6h\\'601l,t11(l the balance of the stove-body is filled by an upper oven. and a lower oven, with a lateral top fine, A, over the upper oven and beneath the stove-top S and lids L, a vertical side line, B, leading from said top flue, A, down the side of the stove most remote from the fire-p0t and past both ovens, a lateral bottom flue, C, leading from the lower end of said side line, B, back across the stove beneath the lower oven, :1 short vertical flue, D, leading from said bot tom line, C, upward past the other end of the lower oven, and an intermediate lateral flue,

E, leading from the upper end of said short j agitating the grate to shake or dump the fire,

all of which form no part of the present i11- vention.

At the rear oi the stove disposed a smoke-flue, F, preferably located about centrally behind the ovens, which line connects at its lower end with the rear of the interme diate flue, E, and above with the rear of the top fine, A, its top opening into the chimney. At the point of connection between the smoke flue F and intermediate flue, E, the sides of the former are extended into the latter, and at their open ends f converge slightly, whereby the heat,when passing from said intermediate flue into the smoke-flue, will be slightly retarded, thereby increasing the heat at that point.

The top flue, A, is divided by a central partition, a, running entirely across above the upper oven, and extending from the stove-top S (which it joins on a transverse line between the front and back lids) down to the top of said oven. The upper flue is open at both ends and at the back into the smoke-flue. A damper, 1, is provided across the rear half of the upper flue, A, at that end next the fire-pot, the handle of which damper is led to the exterior of the stove at any suitable point. The heat from the fire passes at all times through the front half of the flue A into flue B, and may be conducted also through the back half, when desired, by opening damper 1. In the latter event a damper, 2, between smoke-fiue F and upper flue, A, is opened, whereby a direct passage is formed from the fire-pot to the chimney. hen, however, damper 2 is closed, (damper 1 being either open or closed, as desired,) the heat will pass through fiueAacross the top of the stove to and down side flue, B. In this case, in order to heat the upper oven, damper 3 is opened to the dotted position in Fig. 2, when the heat will be thrown directly into fine E below the upper oven, whence it passes out at the rear into smoke-fiue F and off in the chimney. The upper oven may now be used for cooking purposes and the lower oven be slightly warmed for a warming-oven.

hen it is desired to heat both ovens, the damper 3 is closed, and damper 2 also closed, (see full lines, Fig. 2,) when the heat will pass across through flue A, down flue B, across flue 0, up flue D, (passing entirely around the lower oven,) and thence through fine E into smoke-flue F and out the chimney.

It will thus be seen that we can heat the several parts of the stove, as in the cases above provided, by simply operating the dampers l, 2, and 3 without respect to the ordinary draftinlet damper in the ash-pit front or to the outlet-draft damper in the smoke-pipe, if one be used.

Modifications may be made to a considerable extent Without departing from the spirit of the invention, the more so from the peculiar nature of the device. W e can employ one or two of the dampers without the other two or one, or make other changes which would appear advantageous and would suggest themselves to any mechanic skilled in the art.

lVhat we claim as new, and desire to secure by Letters Patent, is

In a stove, the combination of the fire-pot, the stove top, the upper flue, A, extending across beneath said top, the upper and lower ovens disposed beneath said upper flue, A, the vertical flue B, leading from flue A down the end of the stove, the lower flue, 0, leading thence back beneath the lower oven, the short vertical flue D, leading thence upward past the end of the lower oven, the intermediate lateral flue, E, leading thence between the ovens and connecting with said vertical flue B, and the smoke-flue F, communicating with the rear of the upper and intermediate lateral flues, A and E,with the damper 2 between the smoke-fine and flue A, and the damper 3, for opening fine E into flue B at will, as and for the purpose set forth.

In testimony whereof we aiiix our signatures in the presence of two witnesses.
