IMPROVEMENT IN PORTABLE RANGES.

Specification forming part of Letters Patent No. 153,900, dated August 1l, 1874; aPPHGMOD filed September 3, 1873.

To all whom Ait may concern:

Be it known that I, FEEDEIGK J. KENNY, of Boston, Massachusetts, have invented Im provements in Portable Ranges, of which the following is a specification:

This invention relates to the class of stoves known to the trade as portable ranges.

Like letters indicate like parts in all the drawings.

Figure I is a perspective view of the range. Figs. II, III, and IV are sectional views of the same.

A is the re-pot, surrounded by coil-pipe a; b, the grate forming the bottom of the lire-pot. c is the sifting-grate. B B are the coal-boxes. G is the ash pit or box; D D, the water-heaters, d, the lines under the pot-holes; c, the blower 5 f, the damper in front of upper part of fire-box 5 g, the hinges of the water-heaters5 h, the side dampers 7c, the back damper; l, damper which controls the flow of the products of combustion in the exit-passage, E, the uptake; F, the enlargement of the uptake; G Gr, the ovens 5 H, the hot-closet; I, the draft-regulator; m, the draft-damper; n, slide closing the opening in the regulator I; K, the waterback. p is the ledge around the outside of the ovens to receive the lagging. q is the partial partition of the draft-regulator. r and r are the parts of the funnel leading to the chimney-on each side'of the regulator.

The stove or range may be considered in two parts-the base or lower division, containing the fire-pot A, ash and coal boxes B and G, hot-water tanks K and D, and ilnes under the pot-holes d; and the upper part or division, which includes the ovens G, hot-closet H, and regulator I. The base or lower part of the range is built with the fire-pot A in the center of the front half, a coiled water-pipe, a, connected with water-back K, surrounding and forming the sides. The bottom is a sliding removable grate, b, resting on ledges on the side of the firepot. Underneath this grate is a hip-grate, c, with its center higher than the ends, the grate-bars sloping from the center to the coal-boxes B B arranged on either side. The ashes from the re fall on the inclined grate-surfaces c, and the line ashes sift into the ash-pit O, and the coal slides down on either side into the coal-boxes B B placed to receive it, and which, as well as the ashreceiver G, are arranged as drawers. The iront of the stove is made as a blower, e, closing the lower part of the fire-pot. Above this is a door suspended by hinges, and which opens outward and downward, and forms a top damper, f. Adjoining the tire-pot on each side, and forming the two front corners of the stove below the pot-tlues d, are two reservoirs, D, for hot water, which are hung upon hinges g at the sides of the stove, and can be swung upon said hinges outwardly, so that their contents can be reached from the front or ends of `the range, as may be desired. On each side and at the back of the fire-pot are dampers hand k, placed to regulate the passage of the heat to the side or pot ilues d and to the uptake E. The back damper 7c is generally closed when boiling is going on, and the side dampers h when a hot quick oven is desired. Each of these dampers has a coal-guard, s, on the lire-pot side. The entire back of the lower division, below the pot-lines d, is a hot-water tank or reservoir, K, the water being heated by passing through the coil-pipes a that surround the nre-pot, and by direct contact of the re with the plate of the water-back. rllhis reservoir K is of sufficient size to answer all the purposes of the ordinary boiler or hot-water tank used with ranges. The uptake E runs to the fines surrounding the two circular or oval ovens Gr, which are made of single sheets of sheet-iron, and removable from the surrounding frame, if desirable. Above the uptake the tlue is divided into two parts, each passing completely around the cylindrical ovens G as a single-sheet iue, and uniting again just above the point of separation. The ovens are formed with a ledge at the edges p, which may be lagged to prevent radiation. In the uptake E is a damper, l, by which the heat can be completely turned oft' from one oven, if desired. The ovens G are made cylindrical or oval, and surrounded by singlesheet lues, leading rst outward and upward, then upward and inward, then inward and downward. From the upper end of the uptake E the smoke-passage enlarges into two chambers, F, one on each side. These cominunicate with the smoke passages or fines around the ovens G. Through a door, L, in

bined With the tire-pot A and ilue'sl d, in the manner and for the purposes set forth.l

3. The uptake E, chambers F, damper l, and ovens G, having the single sheet iiue, the several parts combined in the manner and for the purposes set forth.

4. The combination of the fire-pot A, coilpipe a, water-tank K, iiues d, with the hinged reservoirs D, substantially as and for the purposes set forth.
