IMPROVEMENT IN RESERVOIR COOKING-STOVES.
Specification forming part of Letters Patent No. 83,407, dated Dctober 27, 1868; reissue No. 5,124', dated October 29, 1872, reissue No. 5,8114, dated April 21, 1874; application filed December 30, 1873.
To all whom t may concern Beit known that I, J ULrUs F. QUIMBY, of the city of Troy, county of Rensselaer and State of New York, have invented certain new and useful Improvements in VVaterReservoir CookingStoves or Ranges; and I do hereby declare that the following is a full and exact description of the same, reference being had to the annexed drawing and to letters of reti erence marked thereon, forming a part of this specification, in which- I Figure l isa perspective view of a cookingstove, and showing my improved water reservoir or tank attached thereto,and connected therewith by my improved manner of construction thereof. Fig. 2 is a vertical longitudinal sectional view taken at the dotted line .fr of Fig. 1. Fig. 3 is a top or plan view of my improved water-reservoir cooking-stove, with the reservoir top plate and a part of the stove top plate removed to show more clearly my said improvements therein. Fig. 4 is a perspective view of the reservoir-casing' with the reservoir removed, showing by the arrows the motion of the heat or products of combustion. Fig. 5 is a vertical section of the rear part of the stove, showing the case with reservoir removed. Fig. 6 is a top or plan view with reservoir removed. Fig. 7 is a view of the outside of the stove-back with the reservoir-casing removed. Fig. 8 is a vertical section of the rear end of the stove with the back plate and reservoir -case removed, showing the top, rear, and bottom lines. Fig. 9 is the damper that closes one of the openings through the back-plate, so as to shut oil'v the heat from the reservoir.
The same letters refer to like parts in each of the said figures.
My said invention relates to improvements in that cla-ss of cooking-stoves.provided with a waterreservoir 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 operation7 to wit: f
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 a and a, respectively, in
Ying the upright sides or jacket to said reservoir. The casing is now complete, inclosing on all sides the reservoir C, 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 C, and inclosing a space or chamber between said walls or sides, which, bein g full of air retards and prevents the cooling ot' 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 the outer casing, and the said chamber or space forms also a flue, c, 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 line therefrom, and which may divert a portion of the heat therefrom, which passes in a horizontal direction around the reservoir C and inside of the outer case E in the flue c, substantially as shown in Figs. 1 and 3 of 'the annexed drawings, to thereby more rapidly heat the water in the tank C. This water-reservoir casing, as thus constructed sub stantially, 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 manner such that the projecting top and bottom edges of the flan ges 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 eX- terior wall or rear side B 'ofa cooking-stove, so as to thereby forin'atransverse flue, b, between the water-reservoir C and thel exterior wall B of the stove, which separates the ue b from the stove-fines c and f, or their equival lent fines, which are, by means of the induction and exit openings a and a aforesaid, connected with the said reservoir-due c, and the transverse due l) connects at each end with the end of the flue c near the apertures ce and c', in manner substantially as shown in Fig. 3. The induction-opening a is provided with the damper d, with which to close itwhenever desired, so as to send or divert all the hot products of combustion under and through the oven-dues. A damper, Gr, is arranged in the ,usual manner within the top flue of the stove to shut off the direct draft to the exit-pipe, when so desired, to thereby send the heat through the oven-fines and also through the reservoir-due b. The reservoir-top is provided with lids or covers which are attached to the top rim D.
To operate this improved water -reservoir cooking-stove, close the direct-draft damper G and open the water-reservoir Hue-damper d.
The heated gases or products of combustion now pass to the descending iiue e, thence through the induction-opening a into the reservoir-fines c and Z1, circulating therein around and about the sides and ends of said water-reservoir 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 water hot within said reservoir. The heated gases pass-thence through the opening d into the rising exit-flue f, thence into the exit-pipe, as shown. The amount of heat passing into said reservoir-dues is easily regulated by said damper d, by partially closing the opening a, therewith,so as to graduate the-temperature Yof the water in said reservoir from warm to hot and hot to warm, as may be wanted, and when no hotwater is wanted to entirely close said damper d, which thereby diverts all of the heated gases through the ovenflues.
This improved water reservoir may be adapted and applied to three-ilued77 and other varietiesof iiues in cooking-stoves, by shift-V ing, if necessa y, the location of the eXit-opening ce', so as to always connect it with the ris ing exit-flue of the stove, and by shifting, if necessary, the induction-opening a, so as to always connect with the descending or diving ilues thereof, thus shifting their positions respectively, whenever necessary, to suit the particular arrangement of stove-ilues in each case to which the improved water-reservoir may be applied. t
The damper d is placed in the divin g-ue opening a, though any equivalenta producing the same result or movement of heat in front of the reservoir may be used.
It will be seen that the products of combustion pass directly from the firebox rearward against the reservoir in the descending flue or flues, and immediately thereafter turn inward on 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. 4 and 6, that therev must be an inlet and an outlet,'an induction and an exit passage, for the products of combustion, the' inlet-openings connected with the`downward rear fines of the stove, while the outlet-opening is connected with the ascending rear Ilue ofthe 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 of the cooking-stove, so as to enlarge the reservoir by increasing its depth, without occupying the 4space below the reservoir 5 and again, it will be seen by Figs. l and 2, that the reservoir comes quite down to the plate F-that is, to the bottom of the casing-so 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 thev reservoir, but rapidly and quickly inV front of it by direct heat from the fire-box.
Heretofore, reservoirs have been heated from below, or bythe motion of the heat up and down the rear upright fines, 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 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 C in its place, and connects and forms close joint with it.
It will be observed that the pipecollar in front of the casing occupies its usual position over the rising rear flue of the stove, and that the hot products of combustion may enter into the casing; but they must return again before passing into the smoke-pipe.
There is nothing to compel the heat of thc flues to pass into the casing, and nothing to compel it to pass around the reservoir in the flue c. It is simply allowed to pass into the reservoir-chamber, which latter is simply aux iliary to the rear fines, acting merely as an assistant to said flues in their double office of heating the oven and the reservoir.
It will be seen that the size of this reservoir with reference'to the size of the casing is not au essential point, as with previous cased reservoirs, because it is not necessary to the free |and perfect operation of the stove that any ilue-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 oi cased reservoir heretofore made, without 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 lue passes through the inclosing-cha1nber 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 iiues of the stove, that the reservoir may be enlarged to lill the casing, or diminished so as to only partly iill it, and yet no working quality of the stove would be altered or even injured thereby, the only eiiect being the in` creasing or the diminishing of the heat the reservoir would receive from the rear iiues of the stove through the openings in front of it.
'As before stated, very little, if any, heatthat is, active heatwill pass through the lue c, practically, then, the space at each end, and on the rear of the reservoir, is simply a dead-1iue space, the office or use of which being merely to hold and preserve the penetrating heat and gases of the active iiues in front of the reservoir.
I am aware that a casing for a water-reservoir is not new inv itself, having been invented by others; nor is it new to place a reservoir in rear of a cook-stove; therefore, neither feature is broadly claimed here.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. A casing for a waterreservoir, located.
on the rear end of a diving-flue cooking-stove, the exit-pipe of the stove retaining its usual position over the ascending rear flue in front of said casing.
2. A casing fora water-reservoir, formed on the rear end of a diving-liuc cooking-stove, and in rear of the exit-pipe and back ilues, and, in combination therewith, a portion of the back of the stove being removed to admit heat or the products of combustion to traverse the ascending and descending iiues and the interior of the casin g.
3. A casing for a water-reservoir, located on the rear end of a diving-Hue cooking-stove, having its top portion elevated above the plane of the top plate of the stove, and in combination therewith, the bottom of the reservoir being below the top plate, and in rear of the back tlues, and in communication there` with.
4. Acasing for a water-reservoir, located in the rear of a diving-flue cooking-stove, and, in combination therewith, the said casing being provided with a top plate elevated above the plane of the top plate of the stove, and
connected therewith by a downwardly-projecting inclined iiange or plate.
5. For a diving-nue cooking-stove, a rescrvoir and casingcombined, the bottom of the reservoir and the bottom of the casing joining with or coming to, or nearly to, each other for enlarging the space below said casing in rear ofthe stove.
6. A water tank or reservoir, situated in rear of a diving-hue cooking-stove, and in combination with the rear iiues thereof, said rear lues being connected with each other by a damper or dampers, opening or openings, forming a transverse or cross ilue in front of the reservoir, permitting the heat or heated products of combustion to pass from the descending ilue or ilues to the ascending iiue, and thereby heating the reservoir intheir passage.
7. A reservoir-casing formed on the rear end and behind a diving# iue cooking stove, and, in combination therewith, inclosing a space or chamber, which connects with the descending rear nue or ues of said stove, whereby the air or the reservoir contained therein may be heated by the products of combustion passing into or through said ilues.
8. Areservoir-casin g formed below, or partly below, the top, and in rear of a diving-nue cookingstove, and in combination therewith, inclosing a space or chamber, connecting with the rear ascending iiue of the stove by an openin g, whereby the air or the reservoir contained in said chamber maybe heated or receive heat from said flue as the products of combustion pass therein upward to the eXit-open ing, said opening being placed over and connected with said flue in the usual manner.
9. The water-reservoir, heated by direct draft from the iireboX by means of a cross iiue formed in front of the reservoir, and in combination therewith, and in rear of the oven, by which the heated products of combustion are allowed to pass from the downward to the upward flues on the front or side of the reservoir, and in close contact therewith.
'10. A casing for a reservoir inclosed therein, and in combination therewith, situatedhin rear cfa diving-tlue cookingstove, having its inclosing chamber connected with rear iiues, thereby permitting the products of combustion, in passing through said ilues, to pass over, along, or against the inner front or side -ot' the reservoir before they enter the exitpipe, located over the ascending'flue of the stove.
11. In combination with an active lue in front of a reservoir, situated within a casing in rear of a diving-nue cooking-stove, a confined or dead-flue space created on the ends and rear side of the reservoir for holding and containing the penetrating products oi' combustion which emerge from an active flue in front, and which may assist in heating the reservoir.- p l2. The combination of a horizontal plate, projecting from the rear plate of a divin gne cooking-stom below the opening in said rear' plate7 for forming with the upright plates the casing, and for supporting the Water-reservoir iuclosed therein.
13. In combination with a, water-reservoir, situated in rear of at diving-Hue cooking-stove, 2L damper placed at the front of the reservoir,
and to the rear of the oven, by the opening of A which the heat, smoke, or products of coml bustion are permittedt' pass from thJ downward t0 the upward. rear ues in front of and against the reservoir, and by the closing of which they are made or allowed. to pass under the oven.
