IMPROVEMENT IN RESERVOIR COOKING-STOVES.

Specification forming part of Letters Patent No. 146,969, dated January 27, 1874; application filed January 16, 1874.

To all whom fit ma y concern:

Be it known that I, GURDON G. XVOLFE., of Troy, in the county of Rensselaer and in the State of N ew York, have invented certain new and useful Improvements in Cooking-Stoves; and do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this speciiication, in whichy Figure 1 is a perspective view of the rear end of a stove containing my improved waterreservoir. Fig. 2 is a rear elevation of the same withthe reservoir and its casing removed. Fig. 3 is a vertical section of said stove upon a line extending from front to rear, through the center or ascending` flue, and Fig. 4 is a like view of the same upon a line passing through one of the side or descending ues.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to enable water within a reservoir attached to a stove to be heated in an expeditious manner without interference in any material degree with the operation of the oven; and it consists in a cooking-stove provided .with a chamber for receiving and inclosing a water-reservoir situated in rear of the vertical iiues and below the top plate, communicating at its lower side with the descending lues by means of a dampered aperture, and having its front central portion extended forward to the back ovenplate, substantially as and for the purpose herein after specified.

In the annexed drawing, A represents the top plate, B and B, the side plates, and C the rear end plate, of a cooking-stove, provided with an oven, D, top ue E, and descending and ascending flues F and G, respectively, all in the usualma-nner. Secured to or upon the rear end of the stove, from the top plate A downward, is a casing, H, which has, preferably, such lateral dimensions as to bring its ends ilush with the side plates B B, while from front to rear, and in a vertical direction, the dimensions of said casing are suited to the capacity of the reservoir to be contained therein. From a point near the top plate A downward to the lower side of the chamber I, formed by the casin g H, the end plate C is removed in rea-r of the center or ascending ilue G, so as to combine said ue and chamber, and cause the ascending current of heated gases from the former to expand into and circulate through the latter before escaping into and through the exit-iiue K. Near the lower side of the chamber I the end plate C is removed in rear of each descending flue F, so as to form an opening, L, which corresponds in size to the transverse area of said iiue, so as to permit the contents of the latter to pass rearward through the former into said chamber. A damper, M, is provided for each opening L, which damper may be pivoted at its lower edge so as to turn forward and close the flue F while unclosing said opening, as shown in the drawings, or it may be constructed in any well-known manner, so as to enable said opening to be opened or closed without reference to said iiue. rEhe chamber I is now ready for the reception of the reservoir N, which, as seen, is supported by the top plate h of the easing H, or in such a manner as to bring its upper edge against the same, and has between its sides and bottom a space for the circulation of the heated escaping products oi'combustion.

If desired, the upper end of the center or ascending flue G may communicate with the top oven-due E, in the usual manner, by means of a dampered opening; but I prefer to have such' communication eut olf by a fixed fluev strip, or by extending the rear oven-plate d upward at such point to the top plate A.

The stove is now complete, and operates as follows: When the oven is not required for use, the dampers M and M are opened, and the heated gases from the fuel-chamber pass rearward through the top oven-flue E, downward into the descending lues F and F, and rearward through said openings into the chamber I, from whence, after circulating around the reservoir N, said gases pass into the ascending iue G, and from thence into the exit-fine K, having, during their passage through said chamber, imparted a large percentage of their heat to the liquid contents of said reservoir. When the oven is in use, the dampers M and M are closed, and the heated gases pass downward through the entire length ofthe descending dues F and F into and through the usual bottom oven-flues, and thence upward through theascending flue G to the chamber l, into which they expand, and after circul ation around the reservoir7 are drawn outward thronghthe upper end of said line (l.

lt will be seen that while during` the use otl the oven the gaseous products of combustiml are not forced to pass into the cl1a1|1be1'l,"ai1d that while heating' said oven said gaseous products have parted with a portion oi' their heat,

upon reaching' the bottom ot' said chamber said gases will natu ally expand into and cir culate through the same, while their temperature will still be far above the boiling-point, and sufficient for all of the requirements oi' the reservoir, and to insure aV good draft in the exit-flue. In addition to the heat of the current of gases, the rear oven-plate d will radiate rearward aconsiderablev quantity of heat, which, while aftordilig material assistance to the reservoir7 will not lessen the etiicielley of the oven, for the reason that at such point said oven always possesses a surplus of heat, which can be spared without injury.

Having thus fully set forth the nature and merits ofmy invention, whatI claim as new is In a cooking-stove, a chamber for receiving,r and containing a water-reservoir, situated in rear of the vertical tlues and below the top plate, communicating at its lower side with the descending fines, by means of dampered apertures, and, having; its front central portion extendin g forward to the back oven-plate, substantially as and for the purpose specied.

In testimony that I claim the foregoing, I have hereunto set my hand and seal this 14th day of January, 1874.
