etters Patent No.91,968, dated June 29, 1869; ant edated Janelfi, i869.

COOKING-STOVE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

ervoir removed;

Figure 4, a vertical section, at or about the line zz in figs. 2, 3, 5, and (i;

Figure 5, a horizontal section, at or about the line y y in figs. 1, 4, and 6; and

Figure 6, a vertical section, at or about the line m min figs. 1, 2, 3, 4, and 5; all of one of my improved stoves.

Figure 7 isa vertical section of a modified part of the same stove,'at or about the line w w in figs. 2, 3,

5, 6, and 8; l

Figure 8, aplan of the same part, with the waterreserroir and top-plate removed; and 4 Figure 9 is a perspective view of the reservoir, without its cover; 1

figures, and the arrows therein indicate the directions in which the gases of combustion pass through the stove.

The distinguishing feature of one part of my invention is the combination, in a cooking-stove, of an oven, A, having a fire-chamber, B, at one end, and the lower part c, of the opposite rear portion of the oven, ex-

tended rearward beyond the upper part (1 thereof, with a water-reservoir, .11 extended below the level of the.

top f of the oven, and over its lowerextended part 0, so that while the oven is diminished in size, somewhat in proportion'to the increase, in distance from the firechamber, and the consequent decrease in the amount of heat received. from the latter, the water-reservoir occupies the otherwise vacant upper rear portion'ofthe stove; and so that when the water-reservoir isof the common width and capacity, the upper rear portion of the stove, where the reservoir is located, in rear of'the upper portion of the oven, may extend rearward no further than the rear upright plate 9 of 'the lower portion of the stove, where the lower part of the oven extends under the reservoir, so as to leave room for a warming-closet to extend vertically, and of equal width and capacity from bottom to top, along the whole rear end of the stove- In carrying out: the aforesaid part of my invention,

.I arrange a line or fines, for the hot gases of combustion, from the fire-chamber along and between, and so as to properly heat the oven A and water-reservoir E -in a suitable manner, and with an exit-passage for the gases, either. in front, or in rear, or upward through the top of the water-reservoir; and I arrange the water-reservoir either wholly or partly below the level of the top cooking-plate h of the stove, and have the rear side t, or the ends j j, or the rear side and ends of the reservoir, either covered by a heating or warming-flue space or casing,-or naked, as shown in the drawing, and have the front side It, or the bottom I, or the front side and bottom of the reservoir, either exposed directly to the hot gases of combustion in the stove, as indicated in figs. 4 and 6, or protected or separated therefrom, either wholly or partially, by an intervening plate or plates, m m, fig. 7.

In the aforesaid drawing- N is a sheet'fiue, leading from the fire-chamber B, rearward, between the top cooking-plate hand the top f of the oven.

O is a sheet flue, leading from the rear end of the flue N, downward, between the reservoir E and the upper rear part of the oven.

P P are -fines extended rearward under the lateral portions of the bottom of the reservoir, and leading downward from the bottom of the flue 0, along the side portions of the rear end of the extended lower part .c of the oven. The same letters refer to like parts in the'difi'erent Q Q are flues leading from the bottoms of the flues PP forward, along the side portionsof the bottom of theoven', and communicating 'at their'i'ront ends with a flue, R, which extends from front to rear along the middle portion of the bottom of the oven.

S'is a flue, from the rear-end of the fiueRnpward,

along the middle of the rear side of the extended lower portion of the oven, and under the middle part of the bottom of the reservoir, and terminating in an exitpassage, '1, just below the rear. side of the reservoir.

U is avalve or damper, arranged between the lower 7 part of the flue O and the upper part of the flue S.

\Vheu the valve U is open, as shown in fig. 7, the hot gases of combustion pass from the fire-chamber B, through the fines N O and the upper part of the flue S, into the exit-passage T.

When the valve U is closed, as in figs. 3, 4, and 6, the hot gases then pass from the fire-chamber, successively through the vfines N, O, P P, Q Q, It, and S, into the same exit-passage.

' In either case, the reservoir is strongly heated, whether the draught is direct or under the oven.

And theabove-described arrangement in a cookingstove, of the lines N, O, P P, Q Q, R, S, exit-passage T, and valve U, in combination with the fire-chamber, oven, having its lower portion extended rearward, beyond its upper portion, and water-reservoir extended below and in rear of the top of the oven, and over the extended lower portion of the latter, constitutes one part of my invention. V 7 Another part of my invention in cooking-stoves. is

a hot-water reservoir, E,'arranged in the upper rear reservoir, so that a \varming-closet, of uniform width.

and size from top to bottom, may extend vertically along, and receive heat directly from both the rear side i of the hot-water reservoir and the outer plate g' of the heating-flue or flues in the rear end of the stove, below the reservoir, as indicated by the dotted lines at no 1: in fig. 7..

In the drawing, the rear side i and ends j j of the water-reservoir are shown resting at their bottoms upon, and forming virtual continuations of the main upright rear plate g and side plates a aof the stove.

What I claim as my invention, and desire to secure by Letters Patent, is-,

The combination, in a cooking-stove, of an oven, A, having the lower part c of the portion farthest from the fire-chamber extended rearward beyond the upper part 01, with a water-reservoir, E, extended below the level of the top of the oven and over the rearwardlyextended lower portion thereof, as herein set forth.

. Also, the arrangement of the fines N, O, P P, Q Q, R, S, exit-passage T, and valve or damper U, in combination with the fire-chamber, oven, having the lower portion extended rearward beyond the upper part, and

\vaterrreservoirextended below the level of the top of
