My said invention relates to improvements in that class of cooking-stoves provided with a'water-reservoir at the back, by means: of

which water can be heated in a reservoir so located with less fuel, and when heated can be kept so for a longer space of time than by any other stove before known.

To enable others skilled in the art to make and use my said invention, I now proceed to fully describe its construction and operation, to wit:

In the annexed drawings, A represents a cookingstove of the usual form of construction, and with the addition thereto, as made in and through its exterior, rear, or end plate B, and at each side thereof, of the induction and exit apertures 60 and a, respectively, in manner as substantially shown in Figs. 3 and 4. The hotwater reservoir O is constructed with a continuous flange or rim, D, projecting outward from its top edges at its front, back, and end sides. The bottom F of this reservoir likewise projects outward at and from its front and back and end sides, respectively. It has also a ridge or small flange, L, upon and near the edge of said projecting plate, that extends around the ends and rear thereof, to aid in holding the upright sides or jacket to said reservoir.

lhe casing is now complete, inclosing on all sides the reservoir U, which is secured to the respective top and bottom projecting rims D and F of said reservoir by rivets or bolts, or by other suitable means, and 'in such a manner as to form double end sides and rear side for said reservoir 0, and inclosing a space or chamber between said walls or sides, which, being full of air, retards and prevents the cooling of water in said reservoir by retarding. and preventing the radiation of heat therefrom by the non-conducting properties of air in said chamber, formed between the reservoir and ontercasing, and the said chamber or space forms also a fine, 0, which, being connected with the diving or descending flue of the cooking-stove A, in the manner as hereinafter described and shown, forms a branch flue therefrom, and which may divert a portion of the heat therefrom, which passes in a horizontal direction around the reservoir 0, and inside of the outer case E in the flue c,

' the reservoir-flue b.

' the water hot within said reservoir.

substantially as shown in Figs. 1 and 30f the annexed drawings, to thereby more rapidly heat the water in the tank 0. This waterreservoir casing, as thus constructed, substantially, is now arranged at and attached by lugs or bolts, or. by other suitable means, to the exterior wall or side B of a cooking stove or range, A, and in a mannersuch that the projecting top and bottom edges of the flanges or rims aforesaid, or the equivalent devices therefor, and the end side edges of the jacket or side casing E of said waterreservoir, may make a close joint with the exteriorwall or rear side B of a cooking-stove, so as to thereby form a transverse flue, b, between water-reservoir G and the exterior wall B of the stove, which separates the flue b from the stove-fines e and f, or their equivalent fines, which are, by means of the induction and exit openings to and a, aforesaid, connected with the said reservoir'flne c, and the transverse flue b connects at each end with the end of the flue 0, near the apertures a and a, in manner substantially as shown in Fig. 3. The induction opening a is provided with the damper cl, with which to close it whenever desired, so as to send or divert all the hot products of combustion under and through the oven-tines. A damper, G, is arranged, in the usual manner, within the top flue of the stove, to shut otf the direct draft to the exitpipe when so desired, to thereby send the heat through the oven-tines, and also through The reservoir-top is provided with lids or covers, which are attached to the top rim D.

It will also be observed that the damper d, Q

by means of its two flanges, opens and closes at the same time both the induction and the exit openings, so that when open a circulation of hot-air currents is obtained through the reservoir-chamber, and when closed a deadair chamber is formed on all sides of the reservoir.

To operate this improved water-reservoir cooking-stove, close the direct-draft damper G, and. open the water-reservoir fine-damper d. The heated gases or products of combustion now pass to the descending flue e,- thence 'through the induction-opening a into the reservoir-flues c and b, circulating therein around and about the sides and ends of said waterreservoir G, in the manner about as shown by the arrows in the annexed drawings, and so as to heat quickly and effectively, and keep The heated gases thence pass through the opening a into the rising exit-fluef; thence into the exit-pipe, as shown. The amount of heat passing into said reservoir-fines is easily regulated by said damper d, by partially closing the openinga therewith, so as to graduate the temperature of the water in said reservoir,

from warm to hot and hot to warm, as may be wanted, and, when no hot water is Wanted, to entirely close the damper d, which thereby diverts all the heated gases through the ovenflues, and forms a dead-air chamber about the front, rear, and end sides of the reservoir.

This improved water reservoir may be adapted and applied to threefined and other varieties of flues in cooking-stoves, by shifting, if necessary, the location of the exitopening a, so as to always connect it with the rising exit-flue of the stove, and by shifting, if necessary, the induction-opening a, so as always to connect with the descending or divin g flues thereof, thus shifting their positions, respectively, whenever necessary, to suit the particular arrangement of stove-fines in each case to which the improved water-reservoir may be applied.

The flange of the damper d, by the opening of which the products ofeombustion are forced into the reservoir-chamber, is placed in the diving flue opening a, though any equivalent producing the same result or movement of heat in front of the reservoir may be used.

It will be seen that when the damper d is opened, the products of combustion pass directly from the fire-box rearward into the descendingflne or flues, and immediately thereafter turn inward into the reservoir-casing, and against the face or side of the reservoir, and pass to the rising or exit flue, thus heating the reservoir by direct draft in a manner wholly new with this improved reservoir.

It will be seen, also, by Figs. at and 6, that there must be an inlet and an outlet, an induction and an exit passage, for the products of combustionthe inlet-openings connected with the downward rear flnes of the stove, while the outletopening is connected with the ascending rear flue of the stove.

It will be seen, also, that the top part of the reservoir and its casing or top rim D are raised above the top plate ofthe cooking-stove, so as to enlarge the reservoir by increasing its depth without occupying the space below the reservoir; and, again, it will be seen by Figs. 1 and 2 that the reservoir comes quite down to the plate Fthat is, to the bottom of the casingso as to still increase its capacity without encroaching upon the space below said plate F, which is needed for the usual hot closet, or for other purposes. The hot products of combustion do not go under the reservoir, but rapidly and quickly in front of it by direct heat from the fire-box.

Heretofore reservoirs have been heated from below, or by the motion of the heat up and down the rear upright flues, passing around the oven at the same time, while in this invention the reservoir is not heated from the bottom, nor does the heat necessarily operate on the bottom of the oven while heating the reservoir.

The plate F is substantially horizontal, and entirely so as regards its outer ends and back edges. This leaves the space for the usual hot-closet unobstructed by a sink or flue space below the reservoir, which is not usual with other reservoirs. The covers to the reservoir are hung to the top rim D, which caps and holds the sides of the casing E,'and also holds the top part of the reservoir 0 in its place, and

from the descending flue or fines into the reservoir-casing. This creates an active flue in front of the reservoir. There is nothing to compel an active circulation within the casing around the ends and back of the reservoir, the caloric merely expanding in this fine 0.

It will be seen that the size of this reservoir with reference to the size of the casing is not an essential point, as with previous cased reservoirs, because it is not necessary to the free and perfect operation of the stove that any fine-heat or flue-smoke pass through it. Thus the reservoir may be enlarged or diminished at will, which cannot be done with any other style of cased reservoir heretofore made with out injuring the operation of the stove itself. This is regarded as a very valuable improvement, for the reason that, in order to secure a reservoir of proper size, when a flue passes through the inclosing-chamber, the chamber itself must be disproportionately larger and cumbersome; or,'in other words, with such construction of casing the reservoir would not only have to be very small if the casing were not an overgrown incumbrance, but the water in it would be continually boiling away, and wasting itself in steam in the room, which would be both disagreeable and injurious. It is an essential point, therefore, that this casing is so constructed with reference to the fines of the stove that the reservoir may be enlarged to fill the casing, or diminished so as to only partially fill it, and yet no working quality of the stove would be altered, or even injured thereby, the only effect being the increasing or diminishing of the heat the reservoir would receive from the rear fines of the stove through the openings in front of it.

As before stated, very little, if any, heatthat is, active heat-will pass through the fine 0. Practically, then, the space at each end and on the rear of the reservoir is simply a dead flue-space, the oflice or use of which being merely to hold and preserve the penetrating heat and gases of the active fines in front of the reservoir; but, as also above referred to, if it is desirable not to divert any of the products of combustion from the bottom oven-fines, and direct active currents impinging upon the reservoir are not necessary to heat the water contained therein to the desired temperature, the damper d may i be closed and this result accomplished. The flanges then close the apertures leading from the rear fines to the reservoir-chamber, thus forming a dead-air chamber on all sides of the reservoir, which, not only preventing the radiation of heat from the reservoir, but, acting at the same time as a chamber to receive the caloric penetrating through the back plate from the rear fines, forms a desirable and gentle means of heating the water contained in the reservoir.

I am aware that a casing for a water-reservoir is not new in itself, having been invented by others; noris it new to place a reservoir in rear of a coolcstov'e; therefore, neither feature is broadly claimed here.
