specification forming part of Letters Patent No. 56,686, dated July 24, 1866 reissue No. 6,785, dated December 7, 1875 application filed July 8, 1873.

To all whom 'it may concern:

Be it known that I, EsEK BUssEY, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvementsin (looking-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. The invention protected by these Letters Patent relates to that class of cooking-stoves which have a reservoir arranged behind the rear flues, and the nature thereof consists primarily in the employment and location of an intermediate plate in the real` of the exitpassage, and between the back oven-plate and the reservoir. It also consists in locating a reservoir heating-chamber between the oven and the reservoir without removing the exitpipe from its usual position immediately in the rear of the oven and over the ascending' fine. It also consists in placing a reservoir heatingchamber behind the ordinary rear flues of the stove, in such a manner that the'hot gases passing down the side flues will expand into said chamber. It also consists in placing a reservoir heating-chamber between the reservoir and ascending flue, and in the rear of the exit-pipe, inv such a manner that the heated gases passing up the ascending fiue will ex- It also consists in providing said intermediate plate ,with openings, whereby a communication is established between the reservoir heating-chamber and the rear Vertical fiues of the stove. It also consists in dividing the reservoir-chambeninto compartments by extending the flue-strips of the rear Vertical fiuesdiack of and beyond the intermediate plate, into said reservoir heatimg-chamber, and between said intermediate' plate and the front of the reservoir.

In the accompanying plate of drawings, in which corresponding parts are designated by the same letters, Figure lis a perspective view of a cooking-stove provided with a reservoir attachment, located behind the ordinary rear flue-space of the stove. Fig. 2 is a Vertical longitudinal section through the ascending fiue of the stove. Fig. 3 illustrates the top plate of the stove. Fig. 4 is a perspective view of the rear part of the stove, with the reservoir removed in order to clearly illustrate the hotair chamber and flue-strip. Fig. 5 is a Vertical longitudinal section through the ascending flue of the stove.

The various parts ordinarily found in a diving-flue stove, arranged With reference to each other in the usual way, are designated by the letters :B S G K L J-that is to say, B is the .top plate of the stove. S is the top flue above the oven. G is the-oven. K is the damper, which, when open, allows the heat to pass directly to the exit-pipe, land when closed causes the heated products ofcombustion to fiow down the side flues. L is a side descending flue. J is the exit-pipe. To the rear'of stove, composed of these old and well-known elements, which have long been in successful use, I attach the reservoir A; but, as the mode of attaching said reservoir forms no part of the present invention, it needs no particular description. The reservoir rests against the plate I, which performs the twofold function of supporting the reservoir and constituting the back of the lower part of the reservoirchamber Fl, which extends beneath andv up the front side of the reservoir. Between the reservoir and oven, and at any distance from the reservoir which may be ,deemed desirable, is placed the intermediate plate F. This intermediate plate constitutes the capital feature of the present invention; and it is confidently asserted that these Letters Patent afford the first example of an intermediate plate so located in the rear of the exit-pipe as to perform the twofold office of the ordinary back plate of a (living-flue stove and fron't plate of a reservoir heating-chamber.

The advantages which accrue from the use of the intermediate plate are as follows: First, when the direct draft is used, the products of combustion, on their way to the exit-pipe, ra-

'diate an intense heat upon that part of the reservoir which is least qualified to bear its effects-i. e., the front wall of 'the reservoir above the water-level. By the use of the in- -the o-ven.

termediate plate this part of the reservoir is thoroughly protected. Second, when the return-draft ,is used-or, in other words,- the heated currents flow down the side fiues, under the oven, and back through the ascending flue to the exit-pipe the use of the intermediate plate prevents the gases from being so suddenly cooled as they would be if the frontplate of t'ne reservoii' forln'ed the rear casing of the fiues. Third, by locating the intermediate plate as described a reservoir heatingchamber is formed without changing the exitpipe from the position it usually occupies.

The size -of the reservoir heating-chamber will depend upon the distanee at which the intermediate plate is placed from the reser-v voir, and this, as hereinbefore stated, may be VVaried at ple-.isure without in any way ai'ectgases expand into the reservoir heating-chamber are designated by letter H. The apertures c in the upper part of the intermediate plate, opening into the flue-space, are intended to produce a circulation of hot air along the front ot' the reservoir, and between it and the intermediate plate.

When the damper is open a direct draft is created, and the products of combustion pass at once to the exit-pipe without impiuging or radiating intense heatupon the upper part of the front wall of the reservoir, as they would otherwise do if the intermediate plate were not placed in front thereof. When the damper is closed the heated currents pass down the side fiues, under the oven, and back to the ascending flue, whence they r'each the exit-pipe, expandin g, in their progress through the openings H at the base of the intermediate plate, into the reservoir heating-chamber F' in such a manner as to heat the reservoir without affecting detrimentally the baking qualities of In other words, the intermediate plate may be so adj usted that only that amount of caloric is extracted from the heated gases which is required to heat the reservoir.

The partition-strips N in the reservoir heatimg-chamber are so arranged behind the pipecollar as to divide the said hot-air chamber into compartments, and also form a support, against which the reservoir rests.

I am aware that it is not new to incase a reservoir in a hot-air chamber, and that as long ago as A. D. 1829 a patentwas granted purporting to cover that ground. I am also aware that a reservoir heating-chamber communicatipg with the central flue .only of a three-flued stove, and having the exit-pipe in the rear of the reservoir, has been heretofore invented, but has been found objectionable, owing to the fact that the water in the reservoir is constantly kept at the boiling-point.

Having thus described the construction and operation of my invention, I will indicate in the following elauses what I claim and desire to secure by Letters Patent of the United Statesthat is to say:

1. In a 'stove in which the exit-pipe is allowed to remain in the usual position over'the uscending flue, the combination of the following elements: first, the exit-pipe; second, the vintermediate plate in front of the Vertical heatin g-chamber; third, the reservoir, substanti'ally as described.

2. The combination of the following elements: first, the exit-pipe placed over the aseending flue; second, the Vertical reservoir heating-chamber in the rear of the exit-pilvie third, the reservoir, as and for the pnrpose described.

3. The combination of the following elements: first, the reservoir heating-chamber located in the rear of the exit-pipe; second, the apertures communicating betweenthe lower part of the chamber and the rear flues; third, the rear fiues, as described.

4. The combination of the following elei diate plate and the tront side of the reservoir,

in combination with the flue-stripsin said chamber.

8. The combination of the following elements: first, the hot-air chamber in the rear of the exit-pipe; second, the water-reservoir; third, the partition-strips between the intermediate plate and the reservoir; fourth, the openings conimunicating between the hot-air chamber and the rear space.
