EDWVARD AUSKIN QUISENBERRY, OF LEXINGTON, VIRGINIA.

STOVE.

SPECIFICATION forming part of Letters PatentNo. 719,139, dated January 27, 1903.

Application filed March 1, 1901.

To rtZZ whom it may concern:

Be it known that I, EDWARD AUSKIN Quis- ENBERRY, a citizen of the United States, re-.

siding at Lexington, in the county of Rockbridge and State of Virginia, have invented a new and useful Stove, of which the following is a specification.

My invention relates to an improvement in stoves, the object of my invention being to increase the heating capacity of a stove and to correspondingly effect an economy of fuel; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a front elevation of a heating-stove embodying my improvements. Fig. 2 is a vertical sectional View of the same. Fig. 3 is a horizontal sectional View of the same. Fig. 4 is a detail view.

In the embodiment of my invention here shown the stove A is of the usual construction and is of the type known as the Franklin stove.

In carrying out my invention I provide a series of air-tubes 1, which are vertically disposed and are placed in the back portion 3 of the stove between the rear side of the grate 4: and the rear wall 5 of the stove. The said tubes form the rear side of the grate in the sense that the fuel is in direct contact therewith. To fit the tubes in the stove, the upper and lower sides of the stove are provided with suitable openings through which the said tubes extend, the ends of the tubes preferably projecting slightly above the top of the stove and slightly below the bottom thereof. The said tubes have their lower ends reduced,

as at 6, whereby the shoulders 7 are formed,

which bear on the bottom of the stove, and the said reduced lower ends of the tubes are tapered slightly downwardly to adapt them to be readily fitted in the openings in the bottom of the stove.

It will be understood from the foregoing that the tubes may be readily removed from the stove by lifting them and may be readily replaced by new ones when they become worn or burned out. By thus interposing the tubes between the grate and the back of the stove the said tubes become highly heated, the products of combustion passing between them owing to the draft. The upper and lower ends SerialNo. &9A55. (N0 model.)

of the said tubes are open. Hence external air passes through the tubes, and owing to the heated condition of the tubes the air is heated in its passage through them, thereby greatly increasing the heating capacity of the stove.

It will be observed by reference to Figs. 3 and 4 of the drawings that the air-heating tubes 1 are cylindrical in form, whereby they are adapted to be readily turned in the openings in the top and bottom of the stove to present new surfaces to the action of the fire, and thereby greatly prolong the life of the airtnbes. When they have become worn or burned out, they. may be readily lifted from the stove and replaced by new ones, as hereinbefore stated.

While I have here shown and described my invention as applied to an open Franklin stove, it will be understood that my invention may be used in connection with any common form of heating-stove, and I do not limit myself in this particular.

Any desired number of the air-heating tubes may be employed, and the same may be disposed in a single row or in a series of rows in the hot-air space of the stove between the grate and the smoke-exit.

Having thus described my invention, I claim- A stove having an open, hot-air space between the grate and one of its walls, a series of vertically-disposed open-ended tubes disposed in the said hot-air space between the grate and the smoke-exit forming a wall of the fire-box, and being immediately adjacent the grate, the stove having openings in its upper and lower sides in which the upper and lower ends of the tubes are disposed, the latter being shouldered and tapered at their lower ends and thereby adapted to be readily removed from the stove, said tubes being revoluble in the openings in the top and bottom of the stove to present new surfaces to the action of the fire, for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

EDWARD AUSKIN QUISENBERRY.
