day of May, 1859; and whereas the said Letters Patent, with the addition thereto, havo been assigned and transferred to DANIEL E. PARIS, of Troy, in tbc eounty'oi' Rensselaer, and State of New York; and whereas, the said Letters Patent were believed to be inoperative byreason of a defective specification, and thereupon, and on the 19th day of June, 1866, new and amended Letters Patent were granted for the said invention and additional improvements to me, the said DARH- 1L E.A PARIS, as suoli assignee, which said new and reissued Letters Patent are believed to be inoperative by reason cfa defective specification: I, the said DANIEL E. PARIS, assignee, do hereby declare that the following is ai'ull, olea-r, and exactdescriptiog of the said invention and additional improvements', re'feren n=.\beinrnll had' to tho accompanying drawings, making part of this specification. in which; v

Prior to the said invention of the said Spaulding cooking stoves were in some instances provided with a boiler or reservoir for hot water, either by placing such boiler or reservoir on the top plate of the stove, and

heated by the products of combustion acting on the bottom thereof projecting into the upper due-space, or by forming n duc-space under or around the boiler above the exit pipe of the stove. Both of these -plans were objectionable for the reason that the top of the boiler was too elevated for convenient access, and for the further reason that in one plan the water boiler or reservoir occupied space on .the top plate of the boiler l required for other culinary utensils, and that in the other plan, the boiler or reservoir being heated alone by the products of combustion after escaping from the exit pipe, it could not be suiciently heated without the use of more fuel than was required for the other parts of the stove.' The inconvenience of having the boiler so elevated led to the attempt to place it below the top plate of-the stove by enlarging the Hue-space back of the oven to o. sucient capacity to receive the boiler, but such stove was objectionable for the reason that it had a single flue in which the products of combustion from the {irc-place passed under the oven, up the back, and over the top thereof to the exit pipe in front, and as much of the heat was absorbed by the boiler in the back ne, the products of combustion were so much reduced in temperature before passing over the top, that the heating of the oven was in consequence rendered still more unequal, i

The invention of the said Spaulding, avoids all the objections to the said prior plans, and consists in arranging the water boiler `0r reservoir back of the oven and below Vthe top plate of the stove in combination 4 I with ilues so arranged, that the products oi' combustion pass down, and up back of -the oven before 'reaching the exit pipe. i A

In iig. 1 of'the accompanying drawings, A represents tbe fire-place, and B the ovenrwhich is mainly behind= with n. portion extending under the tire-place. 4 A tube, C, may be used extending down from the bottom of the lire-place for the discharge of ashes into a movable ash-pan, D, below. From the {ire-place the products of combustion pass through n horizontal flue between the top of the oven'and the top plate of the stove to the back, there divide and descend in two diving iues, H H, iig. 2, between the back plate of the oven and the .baekplnte of the stove, one being o n eachsidc of a central ilue, G. vFrom the lower end of these diving i'lues the products of combustion lpass in two side horizontal lncs, I I, between the bottom of the oven and the bottom plate of the stove to the front, andvtlion return through a central flue, L, between the two dues I I to.'

. the back 0n theirl way to the central iiue G,bctween the two diving lucs H H, which leads to the exit pipe J.'

0 zwi The stove s'o far as described is called a three-ilued stove, and was known and used long prior to the invention of the said Spaulding, and is the one to which by preference he applied his said invention, it being recognized as the best plan of diving-tine stove, that is, tho best`of that class of stoves in' which the products of combustion descend and ascend in ilues back of the oven` 'l'hc ilues I I and L are extended for some distance back of the back plate ofthe stove, as at M, and to the top plate of this extension is fitted the bottom of the boiler or water reservoir E, the top of the said extension having an aperture to permit the products of combustion to act against the said boiler to heat the waterl therein. Along the said extension, for a short distance forward of it,

the central flue L is sunken, as represented, and in this extension of the flue L there is a sliding damper, F,

which, when pushed forward in the position represented, causes thc products of combustion tcpass under the boiler or reservoir E, to' the central vertical flue G; as indicated by arrows, but when'it is drawn back they pass directlyinto the said vertical ilue to thc exit pipe without acting directly on thc boiler E. From the foregoing it will be seen that thc boiler or water reservoir is brought down low enough for veasy access, it is out of the way, and, what is very important, the products of combustion can act on it before reaching the exit pipe to give the heat required without the necessity of more fuel than is required for thc ordinary use of' thc stove, whilst at the same time the oven w'illvbe equally heated. And although the best arrangement ofdiving lucs to be used ineombinction wi-th the said arrangement of boiler or water reservoir is that above described, as it best equalizes the heat of the oven, yet it will be obvious that an equivalent, although inferior arrangement, known as the two? flue stove, can be substituted for it, in that the products descendl io one iue and ascend in another leading to the Vexit pipe'. i V 4f 'l And the said improvements of the said Spaulding, which were added to the said patent on the 17th day of May,`1859, consist, first, in locating the boiler orboilers on the hearth properly adapted thereto, in combination with the extension of the bottom dues under the hearth, so that the products of combustion, in passing forward and back to heat the bottom of the oven, shali'aot on the bottom of the boiler tohcat lthe water therein;

and second, in combining with ,the arrangement of dues between the bottom of the stove and thc bottom of the stantially as and for the purpose set forth.

oven, a'surrounding case which extends down to the door, and all around the said bottom (lues, for the purpose i of preventing the said iluos from being cooled by the circulation of-air in the room, and to serve for a chamber to receive articles required to be kept warni.

Figswl, 5, and G, of the accompanying drawings, represent a stove similar to the one described in reference to igs. 1 and 2, with the exception of the projection back of the baal: plate of the stove, and the arrangement of the boiler thereon. The horizontal ilues I I, L, are extcndedunder the hearth, so that products of combus\ tion circulate under the hearth plate', which is adapted to receive one or more boilers E, to be there .heatedA The door ofthe fire-place A is placed at the side so as not to interfere with the boiler or boilers. A casing, N, extends all around and from the base rim O, to the door tov form a hot-air chamber, l", provided with one or more doors. This casing prevents the ilues from being cooled by thcotmosphere of the room, forms a chamber in which to place articles required to he kept warm, and answers as a substitutefor legs.

What is claimed as the invention of the said Spaulding,` is U Arranging the )vater boiler or reservoirrback of the oven and below the tcp plate of the stove, substantially as described, in combination with the arrangement of ilues described, or the equivalent thereof, as and for the purpose described. l v

What are claimed as thc'additional improvements of the said Spaulding, arc l '.l'he arrangement of a boiler or reservoir in frontof the stove, in combination with the extension of the bottom lues of the stove under the said boiler, substantially as and for the purpose described. I
