JAMES T. LAMBERT, OF DETROIT, MICHIGAN.

STOVE.

SPECIFICATION forming part of Letters Patent No. 231,819, dated August 31, 1-880.

' Application filed June 25, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES T. LAMBERT, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Base-Burning Revertible-Flue Heating Stoves, of which the following is a specification.

The nature of my invention relates to certain new and useful improvemen ts in that class ofstoves called base-burnin g and rcvertibleflue stoves, by means of which a more perfect combustion of the coal and its resultant gases is obtained than is had in stoves as ordinarily constructed, and by which the coal is prevented from clogging or stickingin the magazine.

Theinvention is more especially adapted to stoves in which soft or bituminous coal is em ployed as fuel.

Soft or bituminous coal in the magazine of a stove of the class under consideration cakes and swells, and is apt to stick in the magazine and not feed down by gravity to supply the firepot below; and one part of my invention consists in providing means for forcing the coal down when it is found thatit will not feed by its own gravity..

My invention further consists in the new and novel construction of the stove as a whole, as more fully hereinafter described.

Figurel is a vertical central section of my improved stove from front to rear. Fig. 2 is a cross-section on the line no a; in Fig. 1.

In the accompanying drawings, which form a part of this specification, A represents the hollow base, connected with the downward flue B and the ascending flue O, in the usual manner. The descending flue communicates with the space D, surrounding the fire-pot E, by means of the opening a, and when a direct draft is desirecL-that is, when the products of combustion are not to be passed through the hollow base-it is obtained by opening the damper b, which discloses the opening 0 in the flue division-strip cl, thereby allowing a direct communication with the exit a.

F is the ash-pan. G is the fire-bed, preferably a solid circular iron disk supported by proper legs, h, upon the inner walls of the ashpit section. E is the firepot, supported upon or by the wall of the ash-pit section H, so that there is no communication between the latter and the combustion-chamber-I except through the lire-pot.

J is a chamber extending across the top of the descending fine, and the bottom t" of this chamber forms the top of said line and extends to the rear side of the tire-pot, thereby forming a deflecting plate to guide the products of combustion through the opening a. The wall of the combustion-chamber I forms the front wall of the chamber.

K is the top plate of the chamber, and it extends rearward to form the cap of the ascending flue, which is enlarged at top as shown, by the forward curvature of the division fluestrip 61 (which forms the rear wall of the chamber) and the rearward curve of the back flueplate, I, thus forming another chamber over which the plate K extends. Over this latternamed chamber, and in the top plate, there may be a boiler-hole, m, if desired, and the collared exit 6.

The ends of the chamberJ are perforated to admit the outer air into the rear part thereof, and in front of the perforations is placed the strip or plate 0, extending nearly to the top of the chamber, to prevent the too-rapid passage of the air into the combustion-chamber through the opening 19, which affords 'commu- 8o nication between the combustion-chamber and the chamber J.

After the fire is started in the stove the direct draft should be closed, as well as the usual draft-openings in the ash-pit doors, when the air will enter the chamber J through the perforations inits ends, will becomehighlyheated, pass into the combustion chamber, mingle with the gases therein, and, being within the draftforce, will be drawn downward through the 0 incandescent coal in the fire-pot, so that the gases will be entirely consumed.

It will be noticed that the tire-bed is supported at some little distance below the bottom of the fire-pot. This is to allow, under the 5 downward draft, the currents to pass out from the bottom of the firepot without being brought so largely into contact with the tirebed.

K is the outer wall of the magazine-section, I00 and L the magazine, with a flaring mouth opening downwardly and centrally into the combustion-chamber, and having preferably three vertical and elongated openings, 8, at

- equal distances apart.

M represents a ratchet-bar with a downward pitch of its teeth, designed to fit the openings 8, the points of the ratchet-teeth being flush, or nearly so, with the inner face of the magazine. These bars are each pivoted to two links, a, the opposite ends of which are pivoted. to the inner side of the outer wall of the stove in such manner, substantially as shown, that when forced inward the links form radial bars and give a downward motion to the bars, thereby loosening the coal in the magazine and forcing itto feed downward into the fire-pot. These bars may be connected together by a suitable yoke, so as to be operated simultaneously, or they may be operated singly from outside the 'stove by any desirable and proper means.

WVhat I claim as my invention is- 1. In a base-burning revertible-flue stove, an air-heatin g chamber with perforated ends communicating directly with the outer air and provided with the opening 19 and divisionplate 0, said air-chamber being situated above the top of the descending flue and below the top of the ascending flue and communicating with the combustionchamber, substantially as and for the purposes set forth.

2. In a base-burning stove, the combination, with the fire-pot- F, surrounded by the space D, and the deflecting-plate i, forming a division between said space and the air-cham- 'ber, of the descending fine 13, damper b, and

parallel ascending flue O, substantially as described, and for the purpose set forth.

3. The combination, with the air-heating chamber J, having end perforations communieating with the outer air, and opening 19, bottom plate, 2', forming a division between the air chamber and space around the fire-pot, combustionchamber I, fire-pot E, surrounded by the space D, descending flue B, damper I), 1

and parallel ascendingflue (l, substantially as described, and for the purpose set forth.

4. In a stove, the combination of a fire-pot, a fire-bed, a descending flue having no communication with the combustion chamber above the fire-pot and having communication with the space surrounding the fire-pot, a hollow base, an ascending flue having communication with the descending flue by means of a dampered opening between the two said flues, with an air-heating chamber in rear of the combustion -chamber, above the descending flue and below the top of the ascending flue, constructed, arranged, and operating substantially as and for the purposes set forth.

5. In abase-burning heatingstove having a magazine provided with vertical openings, the ratchet-bars having a radial movement, substantially as and for the purposes described.
