To all whom t't may concern: f

Be it known that DANIEL E. PARIS, of the city of Troy, in the county of Rensselaer and State of New York, invented new and useful Improvements in Stove-Reservoirs, which invention was duly assigned to the firm of BUR- DETT, PARIS & Oo., ot' the above-mentioned place, and Iwhich has been assigned by said BURDETT, PARIS & Go. to BURDETT, POT- TER, SMITH St O0., ot' the above mentioned place, and by said BURDETT, POTTER, SMITH & Oo. assigned to JosEPH B. WILKINSON, of the above-mentioned place; and 'I do hereby declare that the following is a fulll, clear, and accurate descriptionthereof, reference being had t0 the accompanying drawings, and to letters of reference marked thereon, like letters representing like parts, in which- Figure 1 is a perspective View lof a cookingstove with the reservoir attached. -Fig. 2 is a sectional View of the same, taken through the center of the stove lengthwise. Figs. 3 and 4 are perspective views ofthe stove and reservoir separated, showin gth'e back ofthe stove and the front of the reservoir. Fig. 5 presents the same view as is seen in Fig. 2, except the dempers I and H areplaced diii'erently, producing a different effect. This invention relates to certain improvements in reservoir cookingstoves; and it consists, tirst, for the purposeot' heating the reservoir only, of a double Hue between the oven and the reservoir, arranged to conduct the products ot' combustion downward in front of the back plate of a cookingstove and upward in rea-r of it; second, in a double-actin g damper situated below or underneath the pipe-collar of a cooking-stove, having its base at or near the back plate of the stove, while its top part shall move from side to side of said pipe-collar, in combination with the reservoir in rear of .and the double tluc below said damper; third, in a pipecollar to a cookingstove situated at one side or end of the stove and over, or nearly over, a double smoke-tine, and in combination therewith, said pipe-collar being placed to receive the currents ot' heated air from either due as the damper below is shifted from side to side of said pipecollar; fourth, in the combination, with a water-reservoir, of" two ilue-dampers, both situated at one side or end ot' a cooking stove or range, and arr-an ged to produce or capable of producing the results hereinafter named; tit'th, in the combination', with a water-reservoirlocated 'in the rear of the rear tlues of a diving-flue cooking` stove, having the pipe-collar in front ot' the reservoir, of a damper or dampers, whereby the gases et' combustion, in their passage from the lire-box to the smoke-pipe, are controlled, so that they can be made to pass down in the rear of the oven only, and return to the exit-passage through a tiue or auxiliary hot-air cham ber, thereby heating the rear of the oven and the water-reservoir.

without passing under the oven; sixth, ina damper or dainpers, located in and in combination withthe rear upright tine or auxiliary hot-air chamber, for controlling apertures in the division .plate, which, when open, Will cause'the gases lof combustion, in their passage from the lire-box to the smoke-pipe, to pass down in the rear of the oven only, and return upward to exit-passage, thereby lheating the lrear of the oven and the Water-reservoir with a direct draft Without passing under the oven; seventh, in the. combination, with a waterreservoir located in the rear ot the rear tlues ot' a diving-due cooking-stove having the pipecollar in front ofthe reservoir, of a damper or dampers, whereby the currents of heated air or products of combustion are reversed t'rom a downward to an upward motion in the rear vertical ue or dues or auxiliary hot-air chainber, for the purpose ot' heating the rear ot theA oven and the inner or front wall ot a reservoir by direct draft from the re-box t0 the pipe-collar without heating the bottom of the oven.

In Fig. 5 is illustrated a sketch ot' a hot closet, the construction of which is described in a former applica-tion of -D. E. Paris, and it is only slightly modified here to adapt itrto vits present situation.

The object ot' this improvement is to sin1- plity former improvements in back-reservoir stoves of said Paris. In his former patents it was necessary to have a separate top to the stove in order to attach the reservoir to it. The inside plates had also to'be altered,but

lin this improvement the reservoir is attached to the ordinary plain-top stove, the only differ-` ence being the casting of the holes L L through thestoVe-top, as seen in Figs. l and 3. The onlyl change now made is in the back plate of the stove; in other words, the plain stove isV put together the plates forming and holding the Yreservoir made under the previous patents, as much as it does to mount or put together all the'other plates of the stove; but in this in vention it costs nothing -at all, except a moments time spent in putting in the bolts, two of which go through the top plate of the stove va-t L L, Fig. 3, andthrough theears P P, Fig. 4, and three more through the ears X, holding and bolting the piece K to the back B.

(Seen in Fig. 3.) v

The reservoir is held firmly to the stove at its top part by means of-'the two'boltsthrough the holes L L, 'while at the bottom it is held firmly to the stove by means of the lugs Q, Q72 Fig. 4,1itting with or in the slots O 0 made at the upper front corners of the piece K. `(Seen in Fig. 3.) The upward and outwardly-projecting reservoir-seat Kuis the same as in the patent of August 18', 1867, except itis smaller,

and the fine It, in front of the reservoir 'and in rear of the back plate of the stove, scom-` billed with `the Hue-chamber formed bythe: piece K, the same'as in the patent alluded tov above, except in this the heat passes directly? .into the exitpipe,` through the pipelcoll'ar Gr,` vwithout again returning to the rear flue or lues of the stove.

The concave shape of the reservoir, being depressed inwardly at its frontv'side, was shown and described in the reissued patent of J. R. Hyde, July 30,1867; said depression being made, in order to throw the heat more to the center of the water, on the principle that the nearer the heat gets to the center of a body, the quicker it is heated.

By means of dampers the reservoir can be heated or not, at pleasure; but in the patent of July 30, 1867, as also i-n the Spaulding patent, the reservoir could not be heated except the oven be heated also. In other words, thev heat had to pass around the oven before he`at-v ying thereservoir, which is a serious drawback in warm weather, vfor hot water is often want?.

ed for cleaning purposes, and a convenient and quick means of heating it is very desirable. With any other cooki1igstove,'as ordinarily constructed, with a water-reservoir ex-l terlor to lts b'ack plate, and the'exit-passage retaining its usual position over the ascend` ing tlue, it cannot be done without first heating the oven, which notonly makes the room very hot, but, by passing'entirely around the oven, the heat is so long in reaching the reservoir thatwhen it comes in contact'therewith a large percentage of the caloric has become1 ahsorbed,'and as a result the water heats slowly; but by the combination here produced the reservoir can be heated quickly without heating the oven, which is done by turning boththe dampers H and I forward, as seen in Fig. 5. Ihe heat then passes down the central back flue of the stove, and thence up in lrear of the back of the stove through the ue It, which is formed by depressing the front side of the reservoir inward, as shown in Fig. 4. The heat then takes the direction of the arrows, heating the reservoir only on its way to the exit-pipe.

By this arrangement the full power of the heat is turned directly upon the reservoir, and the water heated very rapidly, and in'this consists the chief improvement and advantage of this invention.

When the damper I Vis closed, as seen in Fig.2, the heat then passes around the oven in the usual manner, and then, if the damper H be turned forward, the oven and reservoir both are heated, but if it be turned backward, as shown in dotted lines at Hf, then the heat takes the direction of the X-arrows, and the oven only is heated. Instead ot' the damper H, the one shown in dotted lines Z Z, in Fig. 2, maybe used, or it may be placed on the other side of the back plate B, in the ue R. But neither of these arrangements would be as desirable, for then the reservoir could not be heated except the oven be heated also, or else the reservoir would have to be heated in order'to get direct draft.

rEhe present combination of dampers produces four results, viz., first, by turn'ingthe front damper forward, and the back damper backward, a direct draft'is obtained, without lheatin g the oven, or the reservoir either; second, by turning both dampers backward, the oven only is heated; third, by turning both dampers forward, the reservoir only is heated; fourth, by turning the front damper backward, and the back damper forward, both the oven and the reservoir are heated, the latterv with the waste heat of thefues.

Some of these'results have-heen secured before by different inventions-that is, some reservoir-stoves have been made to produce some of these results, but never before, in a cookingstove, as ordinarily constructed, with a waterreservoir exterior to its back plate, and the exitpipe retaining' its usual position over the ascending fine, did means exist whereby the products 'of combustion could be brought'in contactwith the reservoir and thenpass off lto the exit-pipe without first havingV passed under the oven. This'is one-of the most valuable improvements that the state of the art ldisplays in relation to the modern reservoir cookinglstove. rlhe full intensity of the heat is thus thrown upon the reservoir before its power has been appreeiably dissipated.

Other advantages connectedwith the stove described above are its cheapness in production, t'riin g expense in mounting, and the reduction in the size of the seat-1K, thus giving tached at u u. The sheet metal represented by the black line lv fu, in Fig. 5, forms the'bottom and back ofthe closet, and joins with and is held to the reservoir by another cross-bar placed at the lower back corner of the reservoir at u'. The covers to the reservoir are attached directly toits back top edge, and join with and coliform to the back edge or'molding of the stove-top C, which latter is notched into'a little in order to accommodate the top edge ofthe reservoir, and so that it will set up and join with the under side of the stovetop.

The lugs P P may, and perhaps had better, be cast'on the end of the reservoir, near its front corners, rather' than in its front side, as it would probably facilitate molding. The opening N throughV the back plate of the stove is the same, only smaller, as that s'nown in the patent ot" August 13, 1867. Its width corresponds withv the width of the central tlue of a three-flue stove. Its top is on aline With the'bottom ofthe reservoir, and it should pro- .ject downward sufficiently far that its capacity may correspond with that of the central line S and of the reservoir-flue It. The upper opening My (seen in Fig. 3) is not an opening into the stoveiiues, for they remain continually closed by the damper H, so that there is no connection at any time between the tlues R and the rear fines of the stove; nor can the heat, as it passes through the rear ues of the stove, come in contact with the reserver, except 'it pass through the opening' N, as in the former patents 5 nor does the heat, after passing through the chamber N, pass again into the dues of the stove, but directly off into the smoke-pipe through the collar G.

It will be seen that both the dampers I and H strike against the same stop-piece, (seen at J, Fig. 2,) and that the two dampers turn in opposite directions from this common center. It will also be seen that the pipe-collar G stands almost directly over the back plate B. This is done so as to secure a common opening for the tlues. The pipe-collar G may be placed over the ilue R, the back plate B extend upward, and the damper H omitted, but in that case direct draft could only be had by the heat passing' downward through the-opening N, thus heating the reservoir at all times, a very undesirable result, and which is the greatest fault that is found with the old style of top-reservoir stoves. It will be seen, also,

that as the damper H is shifted from one side to the other of the collar G, it operates not only to let the heat in through one ofthe tlues belo\v, but also to shut it oli' from the otherthat is, it' the damper H,in Fig. 2, be turned backward at'H, it not only lets the' heat through the tlue S in the direction ot' the X-g arrows, but also at the same time shuts it oli',- and prevents it from passing through the flue R.. Thus this damperis double acting, produci'n g in `this-respect the same results Yas are` secured iu the patent of July 30, 1867. cBut,

instead of one, there may be two pipe-collarsone over each ofthe upright rear ilues S and -It-and then the damper H would be omitted,

for the back B would then extend upward to the top of the stove; but this would be inferior to my present arrangement, for the heat could not thenbe controlled, unlessy there should be a damper in one of the exit-pipes `above the stove-top before they join together,

or else inone `ot' the tiues below; but 'witlra damper the arrangement would be substantially the same as that here shown. 1 I am aware of boilers with smoke-lines passing through them, as the Pratt and Stewart patents, and others; also, ot' lues made for the passage of smoke, &c., at the rear part of the stove, by the front plate of the boiler, asin Frenchranges and other stoves, and of fluepassages in the boiler-seats, as in the Spaulding patent.. Theseffeatures I do not claim, but only the features and in the lnanner set forth in the drawings and specifications, and in the following claims. I would ad-d that the damper I in front of the pipe-collar is in common use.

The damper H, on bein g turned back out of the rear vertical flue, will cause the draft to take the shortest possible escapeto the pipecollar from the tire-box. To bake and not to heat the back of the oven too much, and to secure a reverse draft, an important feature of the invention, the damper H is turned into the rear vertical flue and the damper I closed, and the hot currents forced down the corner or descending nues, thence under the oven, and return to the pipe-collar. To heat the back ofthe oven and front of the reservoir only without wasting any heat, as heretofore, the damper H is turned forward into the vertical flue, as already illustrated in Fig. 5, in which case the aforesaid damper I is open.

I would add, also, that the piece K may extend backward to the back side of the reservoir, it' desired, or two-thirds of the way back,

and the flue R made to go up through the center of the reservoir, instead of at its front sidethat is, the ue R may be formed by a pipe running through or near the center of the reservoir, and the tine-seat K used to conduct the smoke or heat to said flue from the rea-r tlue or lues of the stove, in the same way that it now conducts it to the tlue It.

Having thus described the improvement, what I claim is 1. For the purpose of heating the reservoir only, a double iiue between the oven and the reservoir, arranged to conduct the products ot' combustion downward in front of the back plate of a cooking-stove, and upward in rear of it, substantially as described. r

2.
