GEORGE XV. WALKER, OFVBOSTON, MASSACHUSETTS.

` 's1-OVE,

Specification i'orniing part of Letters Patent No. 47,474, dated April 25, 1865.

To all whom it may concern Be it known that I, Gnou GE W. WALKER, of Boston, in the county of Suolk and State of Massachusetts, have invented an Improved Stove 5 and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

1n stoves which are designed for warming apartments much heat is lost by reason of too direct a passage of thc products of combustion to the outlet from the stove, and also by reason of the bottom of the stove being so covered with ashes as to be practically a nonradiating surface. A

To increase the radiating-surface ofstoves, to retain the products of combustion long enough to cause them to part with a large portion of their heat, to make the stove send forth heated currents of air near the floor and where the feet can be conveniently warmed, and to make use of the corners of the stove for iues,

which serve to strengthen the structure as well as to convey the gaseous products of combustion, are the objects of my invention.

Figure l is a perspective view of a stove embodying my invention. Fig. 2 is a verti cal section taken through the center ofthe stove from front to rear; and Fig. 3 is a horizontal section taken in the plane of the line z z, seen in Fig. 2, and showing the radiatingbase in plan below.

In these igures, which represents a stove adapted for burning wood, a shows the door through which fuel is supplied, b the passage through which the air to support combustion passes, and c the arrows showing the direction of the current when passing most directly into and out of the stove at the outlet d.

The bottom of the stove upon which the ashes are deposited, and which supports the fuel, is represented by e, while beneath this bottom, with a space intervening, is a hollow .sub-base wit-h which communication can be had through flues formed at f f f f in the corners of the stove, these tlues opening out of the interior of the main part ofthe stove and discharging into the sub-base, the upper plate or surface of which is marked g, and the lower plate or surface h. The nues before mentioned are formed to a great extent of the material making the main part or body of the stove, requiring the addition only of inner tie-sheet, p ppp, (see Figs. 2 and 3,) these making part of the dues at ff ff, which flues are thus formed with but very'little addition to the cost to the stove and to the amountot' its material, while at the saine time the strength of the body of the stove is greatly increased.

I do not wish to beunderstood as claiming herein cylindrical flues madeseparate from and located outside of the `body ot the stove when used in combination with a hot-air chamber extending in front of the stove, such a construction being old and being expensive as compared with mine, and not operating to strengthen and tie together the-main body at its corners. The space between these plates is divided by an arched sheet, shown in dotted lines in Fig. 3, which is open at the front toward the hearth` of-the stove, and makes a passage which communicates with the vertical flue i, seen at the rear of the stove, which connects with the outlet d.

In the passage by which the currents designated by the arrows marked c escape, adamper or valve of any suitable kind is arranged, as at j. When this is closed, it will be evident that the gaseous products of combustion must take the direction of the arrows marked k, passing from the interior of the body of the stove to its corners, down the lines atj'fffinto the subbase at each of its four corners, and thence toward the front into the space under the hearth, and thence through the center or arched-formed iue to flue t' and to the outlet d.

At l, in the upper part ot' the front of the stove is placed a damper or valve, through which air can be admitted to regulate combustion. Two small pipes, m m, pass through the sub-base, and serve for passages by which air can pass into the space between the plates e and g, thereto be heated and expelled in the direction indicated by the arrows u n.

In the sub-base at the front of the stove is a door, o, through which the interior of the sub-base can be got at for removal ofany deposite therein.

It will be obvious that by the construction herein specified two more radiatingsurfaces are obtained than exist in former constructions, each of which surfaces is as large as the bottom e, or larger, as shown in the drawings, and it will also be seen that said surfaces will 2. Also, the construction of astove with lues formed of the material of the outside of the stove-body and of tie-sheets within the body7 when such ues are arranged to convey the products of combustion to heat a hollow extension of the base in front of the stove.

In testimony whereof I have 'hereunto set my hand this 21st day of February, A. l). 1865.
