IMPROVEMENT IN RESERVOIR COOKING-STOVES.

Specifcation forming part of Letters Patent No. 76,292, dated March 31,1868; reissue No. 5,442, dated June 10, 1873 reissue No. 6,2 19, dated January 12, 1875; application liled January 28, 1874.

DIvIsioN C.

To all whom 'it may concern:

Be it known that I, GURDON G. WoLFE, of the city of Troy, in the county of Rensselaer and State of New York, did invent certain new and useful Improvements in Cooking- Stoyes, for which Letters Patent No. 76,292 wereissued to me upon the 31st day of March, 1868, and thereafter duly surrendered andreissued, bearing date of June 10, 1873, and numbered 5,442, which reissued Letters Patent have been found defective in that the specification and claims do not cover and embrace all of the original invention, as shown in the drawings flled in the Patent Office upon the 14th day of February, 1868.

Now, therefore, being desirous of reissuing said reissued Letters Patent, herewith surrendered, I have prepared, and do hereby declare that the following is, a full, clear, and exact description of the said invention, reference being had to the accompanying drawing making apart of this specification, in which- Figure 1 is a perspective view of Imy cooking-stove and water-reservoir as constructed and combined. Fig. 2 is a like view of said reservoir detached from said stove. Fig. 3 is a perspective view of the rear end of said stove, the reservoir being removed. Fig. 4 is a vertical central section of said stove and reservoir upon a line extending from front to rear. Fig. 5 is a perspective view of the rear end of said stove, the reservoir being removed and a different construction of said end shown.

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

My invention has for its objectv the rapid and economical heating of water within a reservoir attached to-or upon the rear end of a cooking-stove; and it consists, principally, in a chamber extending between the rear casing of the ascending flue of a cooking-stove and the front side of a water-reservoir attach ed thereto, and communicating at its lower side with said ascending iiue, and at its upper side with the exit-fine, in combination with a damper, by means of which the upper part of the said ascending iiue may be caused to communicate directly with or be separated from said exit-iue, substantially as and for the purpose hereinafter specified.

It consists, further, in a chamber situated between the rear side of the descending and ascending iiues of a cooking-stove and the front side of a water-reservoir, partially dvided by a central horizontal lfine-strip, and communicating at its lower side with the ascending iiue and at its upper side with the exit-flue, substantially as and for the purpose hereinafter shown.

It consists, iinally, in combining with a chamber situated between the rear side of the vertical ues of a cooking-stove and the front side of a water-reservoir attached thereto,

partially divided by a horizontal Hue-strip,

and communicating through suitable openings with the center or ascending iiue and the exit-flue, a damper for closing the upper portion of said flue, substantially as and for the purpose hereinafter setforth.

In the annexed drawing, A represents the top plate, B the bottom plate, U and C the side plates, D the frontA plate, and E the rear plate, of a cooking-stove provided with a fuelchamber, F, oven Gr, and the usual system of flues. At the rearl end of the stove the side plates, O and O, project rearward beyond the end plate, E, and in connection with a hori- Zontal ange, h, that extends vbetween the lower ends of such projecting portions c and c, for1n a recess or chamber, H, that is open at its rear, and extends from the upper side of said stove downward to a point, preferably, near the vertical'center of the same. Against the rear open side of the chamber His placed a reservoir, 1, the front side of which incloses said open space, and cuts off communication between said chamber and the outer air. Oommunication between the lower side of said chamber and the centerriiue, K, is effected by means of an opening, L, which passes inward through the end plate, E, while a second opening, M, at the upper side of said chamber,

furnishes communication between the same and the exitflue N. Immediately above the opening L is placed a horizontal iiue-strip, O, which extends from front to rear, between the end plate, E, and reservoir I, and laterally corresponds in dimensions to the length of said opening. A damper, 1?, pivoted within the rear side of the center iiue, directly opposite caping products of combustion passing up. ward through the same are caused to enter the lchamber H through the opening L, and impinge against the lower side of the plate 0, which plate, operating as -a deector, causes the current to divide and pass laterally outward in each direction around its ends, after which said gases turn inward, and, unitingl once more, pass through the opening M into the exit-Hue N, having during such passage given off' a large percentage ot' their surplus heat to the contents of the reservoir.

When but little heat is required for thereservoir the damper P is turned upward, so as to open the upper end of the ascending iiue K and close the opening M between the exitiiue N and the chamber H, when the latter becomes practically aY deadair space, which receives heat principally through the rear plate, Rand in a small degree from the eXpansionot` the heated gases from said flue through the lower opening, L, the degree of heat thus obtained, however, beingsufcient to maintain the' required temperature of the liquid contents or" said reservoir.

The construction described furnishes a simple, efficientand convenient means whereby Water withina'reservoir may be rapidly or lessquickly heated, as is desired.

Having thus fully set forth the nature and merits or" my invention, what I claim as new 1s- 1. A chamber extending between the rear casing of the ascending flue ofA a cookingstove and the front side of a water-reservoir attached thereto, and communicating at its lower side with said ascending iiue, and its upper side with the exit-flue, in combination with a damper by means of which the upper part of the said ascending tlue may be caused to communicate directly with or be separated from said exit-flue, substantially as and for the purpose specified. Y

2. A chamber situated between the rear side of the descending and ascending flues of a cooking-stove and the front side of a waterreservoir attached thereto, partially divided by a central horizontal due-strip, and communicating at its lower side with the ascending iiue, and at its upper side with the eXitiiue, substantially as and for the purpose shown.

3. In combination with a chamber situated between the rear side of the vertical iiues of a cooking-stove and the front side of a waten reservoir attached thereto, partially divided by a horizontal flue-strip, and communicating through a suitable opening at its lower side with the center or-ascending iiue, and through Aa similar opening at its upper side with the exit-line, a damper for closing the upper portion of said ascending flue, substantially as and for the purpose set forth.

In testimony whereofv I have hereunto set my hand this 24th day of January, 1874.

GURDON G. VOLFE.
