H EATING=STOVE.

SPECIFICATION forming part of Letters Patent No. 393.018, dated November 20, 1888.

l Application tiled February 9. 1888. SeriahNo. 263,492. (No model.)

To all whom t vmay concern.-

Be it known that we, LYMAN CLARK MAR- TIN and JOHN WILEY HART, citizens of the United States, residing at Iola, in the county of Allen and State of Kansas, have invented a new and useful Improvement in Heating- Stoves, of which the following is a specificatlon. t

Our invention relates to improvements in heating-stoves; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view with a part of the shell or casing of the stove broken away. Fig. 2 is a vertical section taken at right angles to Fig. 1, and Fig. 3 is a detail View of the ash-pan.

Referring to the drawings by letter, A designates a heating-stove -having the usual hearth, B, and grate C at its lower end, and the smoke-pipe D leading from its upper end.

E designates an open-ended tube or pipe extending vertically through the stove, and having its lower end somewhat below the bottom of the stove, and its upper end Hush with the top of the stove, as clearly shown. A short distance above thelower end of the tube I provideit with an annnlarlange,D', through which bolts are passed to secure the tube to the stove.

Fdesignates the opening in the grate,through the center of which the tube or pipe E extends, and G is the ash-pan, supported by the hearth beneath the grate. This ash-pan is madein two sections or members, H Las shown, provided in their adjacent sides with seinieircular recesses J K, which t around the air tube or pipe E, as shown in Fig. 2. One section or member of the ash-pan is drawn out, in emptying, from the front of the stove, and the other one is drawn out from the back of the same, as will be readily understood.

The upper end of the air-tube is provided with a casting, M, upon which I rest the lower ends of a series of concentric heating pipes or tubes, N O P, which extend up through the room to the upper stories of the building. The upper end of the outer tube is arranged Hush with the door of the second story, and is provided with a register, as clearly shown in Fig. l. The next inner tube extends to the third story, and is provided with a similar register, and so on.

In practice are is built upon the grate in the usual manner, and the smoke and products of combustion are carried oft' through the smoke-pipe. The fire thus being in direct contact with the central air-tube heats the air in the same, which at once rises and passes from the open top of the same into the room. The place of the air thus leaving the tube is at once filled by the cold air drawn in through the lower end of the tube, which is in turn heated and caused to pass out at the top of the tube into the room. A constant circulation of the air in the room is thus maintained and the air is thoroughly heated. All of the air in the tube will not pass out into the room in which the stove is placed; but a large portion will pass into the rooms above, thus heating the entire building.

The air-tube can be made in sections, so as to be readily adjusted to the height of the stove, and, if so desired, it may be carried obliquely through the nre-chamber or formed ou the outside of the same.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

The combination, with a heating-stove, of the central air-tube having its lower end arranged below the bottom of the stove and its upper end arranged ush with the top thereof, the casting M in the upper end of the central air-tube, and the concentric pipes having their lower ends resting on the casting M,and each of said pipes having its upper end provided with a register andarranged iiush with one of the tloors of a building, as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
