IMPROVEMENTS IN HOT-WATER TANKS ON GOOKING-STOVES.

TO ALL WHOM IT MAY CONCERN: 7

Be it known that I, DANIEL E. PARIS, of the city of Troy, in the county of Rensselaer, and State of New York,,have invented new and useful Improvements in Stove-Reservoirs, which invention I have duly assigned to the firm of Burdett, Paris, St 00., of the above-mentioned place; and I do'hereby declare that the following is a full, clear, and accurate description thereof, reference being had to the accompanying drawings, and to letters of reference marked thereon, like letters representing like parts, in wh-ich- I Figure 1 is a-perspective view of a cookingstove with the reservoirattached.

Figure 2 is a sectional view of the same, taken through the centre of the stove lengthwise. Figures-3 and 4 are perspective views of the stove and reservoir separated, showing the back of the stove and the frontof the reservoir.

\ Figure 5 presents the same view as is seen in. fig. 2, except the dampers I-and H are placed difl'erently,

producing a different efi'eet. V

In this last figure is also shown a sketch of my hot closet, the construction of which isdescribed in a former application, and it is only slightly modified here to adaptit to its present situation.

The object of this improvement is to simplify my formerimprovements in back-reservoir stoves.

In my former patents was obliged to have a separate top to my stove, in order to attach my reservoir to it. The inside plates had also to be altered; but in this improvementI attach the reservoir to the ordinary plain-top stove, the only diiference being the casting of the holes L L through the stove-top, asseen in figs. 1 and 3. The onlyeha'ngel now make is in the back plate of the stove; in other words, I make my plain stove the some as I make the reservoir-stove, with the exception of the back plate 13, and even this I could use, by

having two loose pieces to close the openings M and N when the stove is used without a reservoir. It costs, to

mou nt'or put together the plates forming and holding the reservoir made under my previous patents, as much as it does to mount or put together all the other plates of the stove, but in this invention 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 at L L, fig. 3, and through the ears 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. The reservoir is held firmly to the stove at its toppart, by means of the two bolts through the holes L L, while at the bottom it is held firmly to the stove by means of the lugs Q, Q, fig. 4,

fitting with or in the slots 0 0 made at theupper front corners of the piece K, seen in fig. 3. The upward and outwardly projccting reservoir-seat K is the sameas in my patent of August 13, 1867, except it is smaller, and the flue R, in front of the reservoir, and in rear of the back plate of the stove, is combined with the flue-chamber formed by the piece K, the same as in the patent alluded to above, except in this the heat passes directly into theexit-pipe, through the pipe-collar G, without again returning to the rear flue or fines of the stove.

The concave shape of the reservoir being depressed inwardly at'its f ront side, was shown and described in i the reissued patent of J. R. Hyde, July 30, 1867, said depression being made in order to throw the heat more to the centre of the water, on the principle that the nearer the heat gets to the centre of a body, the quicker it is heated. The cut-0E damper H, seen in figs. 2 and .5, is the same in effect, producing the same result as'that shown in my patent of July 30, ,1867, although its situation is entirely different. By means of this damper the reservoir can be heated or not, atpleasure but in the patent of July 30, 1867, as also in the Spaulding patent, the reservoir could not be heated except the oven be heated also in other words, the heat had to pass around the oven before heating the reservoir,which is a serious drawback in warm weather, for hot water is often wanted for cleaning purposes, and a convenient and quick means of heating it is very desirable. With any I other back-reservoir stove, it cannot be done without first heating the oven, which not only makes the room very hot, but, by passing entirely around the oven, the heat is so long in reaching the reservoir that 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 both the dampers H and I forward, as seen in fig. 5. The heat then passes down the central back line of the stove, and thence up in rear of the back of the stove thronghthe flue B, 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. When the damper I is 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 backwards, as shown in dotted lines at H", then the heat takes the direction of the red arrows, and the oven only is heated. Instead of the,damper II, the one shown in dotted lines at Z Z in fig. 2, may be used, or it may be placed on the other side of the back plate B, in the flue R. But neither of these arrangements would be as desirable, for then the reservoir could not be heated except the even be heated also, or else the reservoir would have to be heated in order to get direct draught.

My present combination of dampers produces four results never before obtained unitcdly, viz

First. By turning the front damper forward, and the back damper backward, I get a direct draught, without heating the oven or the reservoir either. i

Second. By turning both dampers backward, I hcat thc oven only.

Third. By turning both dampers forward, I heat the reservoir only.

Fourth. By turning the front damper backward, and the back damper forward, I heat. both the oven and the reservoir, the latter with the waste heat of the flucs.

These results have all been secured before by different inventions; that is, all reservoir-stoves produce one or more of these results, but never before have they all been secured in one stove. Thus herein lies the chief value of this improvement, the other advantages being its cheapness in production, trifling expense in mounting, and the reduction in the size of the seat K, thus giving room for aohot closet below, which is made by attaching its upper front corners to the back plate B of the stove, its front wall being formed by said backplate, while its top covering ismade by the bottom of the reservoir. I make the closet very nearly the same as described in one of my applications, filed March 23, 1868. The and frames T T are held together by one or more bottom cross-bars, attached at u u. The sheet metal represented by the black line 11 v in fig. 5, forms the bottom and 1 back of the 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 arc'attached directly to its back top edge, and join with and conform to the back edge or moulding of the stove-top O, which latter isnotched into a little in order to accommodate the top edge of the 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 moulding. The opening N, through the back plate .of the stove, is the same, only smaller, as that shown in my patent of August 15, 1867. Its width corresponds with the width of the central flue of-a three-flue stove; its top is on a line with the bottom of the reservoir, and 1 it should project downward sufficiently far that its capacity may corrcspond'with that of the central flue S, and of the reservoir-flue RI The upperppening M (seen in fig. is not an opening into the stove-fines, for they remain continually closed by the damper II, so that there is no connection at any time between the flue R and the rear flues of the stove; nor can the heat, as it passes through the rear fines of the stove, come in contact with the reservoir, except it pass. through the opening N, as in my former patents; nordoes the heat, after passing through the chamber N, pass again into the fines of the'stove, but directly off irito the smoke-pipe, through the collar G,

It will be seen that both the dampers I and H strike against tllGStllIlG stop-piece, (seen at J, fig. 2,) and that the twodampers turn in oppositedirections from this common centre.

It will also bo'seeu 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 flues. The pipe-collar G may be placed over the fluc R, the back plate B extend upward, and the damper II omitted; but in that case dircct draught could only be had by the heat passing downward through the opening'N, thus heating the reservoir at all times, avcry undesirable result, and which is the greatest fault that is found with the old style of top-reser voi'r.stovcs.

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 of theflue's below, but also to shut it off from the other; that is, if the damper H, in fig. 2, be turned backward at H, it not only lets-the heat through the fiue Sin the direction of the red arrows, but also at the same time shuts it oil, and prevents it from passing, through the fiue R; thus this damper is double acting, producing in this respect the same results as are secured in my patent of'J'uly 30,1867. But instead of one, there may be two pipe-collars, one over each of the upright rear flues S and B, 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 then be controlled, unless there should be a damper in one of the exit-pipcs above they stove-top before they join together, or-else in one of the flues below; but with a damper, the arrangement would be substantially the same as that here shown.

I am aware of boilers with smoke-fines passing through them, as the Pratt and Stewart patents, and others; 'also of'flucs made for the passage of smoke, &c., at the rear part of the stove, by the front plate of the boiler, as in French ranges and other stoves, and of fine-passages in the boiler-seats, as in tho Spaulding patent. These features I do not claim, but only the features, and in the manner set forth in the drawings and specifications, and in the following claims.

I would add that I do not claim the damper H, used to throw the heat around the oven, nor to produce direct draught, for itcan of itself do neither the one nor the other.

I would add, also, that the piece K may extend backward to the back side ofthe reservoir, desired, or two-thirds of the way back, and the fiuc R made to go up through the centre of the reservoir, instead of at its' front side; that is, thefiue R may be formed by a pipe running through or near -the centre of the reservoir,

and the flue-seat K used to conduct the smoke or heat to said flue from the rear flue or lines of the stove, in the same way that it new; conducts it to the flue R.

Having thus described my improvement, what I claim, is

1. For the purpose of heating the reservoir only, I claim a double flue between the oven and the reservoir, s0 arranged as to conduct the products of combustion downward in front of the back plate of a cooking-stove, and upward in rear of it, substantially as here shown and described.

2. I claim a double-acting damper, situated below or underneath the pipe-collar of a cooking-stove, having itsbase 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 flue below said damper, substantially as herein shown and described. i v

3. I claim the back of a cooking-stove as a division-plate for an upward and downward flue, or a double flue at the rear end of the same, in combination with a water-reservoir, when situated substantially as herein shown and described. I

4. I claim a pipe-collar to a cool ing-stove;situated at one side or end of the stove, and over or nearly over a double smoke-flue, and so placed that it shall receive the currents from either flue, as the damper below is shifted from side to side of said pipe-collar, substantially as herein shown and described.

5. I claim, in combination with a water-reservoir, two flue-dampers, both situated at one side or end 'of a cooking-stove or range, and arranged or capable of producing the results substantially as herein shown and specified. r

6. I claim the upright flue R, situated in rear of the back plate of a cooking-stove, connected and in combination'with the flue-chamber K and the pipecollar G, three sides of which flue are formed by the concave shape ofthe reservoir, substantially as here shown and described.

7. I claim the rearwardly and upwardly-projecting flue-seat K, or its equivalent, when used to conduct the smoke or products of combustion from the rear flue or fines of the stove into the flue R, or into a. similar flue 'formedin or near the centre of the reservoir, substantially as herein shown and described.
