ALPHEUS M. BLAKESLEY, OF ROCK ISLAND, ILLINOIS.

STOVE.

SPECIFICATION forming part of Letters Patent No.410,143, dated September 3, 1889;

Application filed July 20, 1888. Serial No. 280,471. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALPHEUS M. BLAKES- LEY, of the city of Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My invention relates particularly to that class of heating-stoves familiarly known to the trade as Oak Stoves; and it is designed to utilize as far as practicable the heat produced by the fuel consumed therein by causing it to Warm a current of external air in a chamber or flue near to, alongside of, in, or partially or wholly surrounded by the fire-pot or fire-chamber with its inlet and exit orifices disconnected therefrom, the heat of the fire causing the air in such chamber or flue to become heated and to ascend, and thereby effecting a continuous circulation of air through such chamber.

My invention will operate effectively and be of practical utility when applied in connect-ion with any variety or class of stoves adapted wholly or in part to furnish heat; but for convenience I will illustrate it in the drawings and describe it in the specification as embodied in the Riverside Oak Stove as at present manufactured by the Rock Island Stove Company.

In the drawings, Figure 1 is a rear elevation of a stove containing my invention. Fig. 2 is a vertical section on the line 00 on. Fig. 3 is a detached view in perspective of the circulating air-chamber F. Fig. 4 is an elevation of Fig. 3. Fig. 5 is a plan view of the base of the stove, with the air flue or chamber in section on the line y y, Fig. 2. Fig. 6 is a plan view of the top plate. Fig. 7 is a plan View of the concentric rings next below the top plate. Fig. 8 is the cover. Fig. 9 is a perspective of the central concentric rings.

A is the base; B, the fire-pot; O, the cylindrical fire-chamber or combustion-chamber.

D is the top plate, having at one side a collar d, to receive the smoke-pipe, and a central opening at d, with preferably a flange depending from the inner edge of the plate.

01 is the cover, provided with openings for the passage of heated air.

D is a ring interposed between the top of the cylinder 0 and the top plate D, the outer edge of which fits over a flange (i d is a vertical ring arranged concentric with the ring D and connected therewith by arms.

The lower part of the circulating air-chamber is shown at E, and of which e e e represent the side walls and onterwall, the part a of the inner wall being formed preferably by a flat section of thefire-chamber, the lower part a of that inner wall being a part of the necting the lower end of the section F to the.

lower section E. The upper end of the section F has a flaring or enlarged part or collar f, adapted to make a close-fitting joint with a ring or flange, to 'be described; or a separate flange or collar f (see Fig.2) may be attached to the upper end of this section.

F is a ring or flange connected by'arms with a smaller concentric ring or flange f which engages with the expanded part or up-- per end of the partF. The ring F is supported between the upper end of the lower section of the fire-chamber and the lower part of the upper section, these parts being socured to each other and to the ring D and fire-pot and base by rods 1) b or in anyother usual or approved way. The upper section G of the circulating flue or chamber is preferably circular in cross-section and of uniform diameter at top and bottom, being supported within the rings (1 f From the above description and the drawings it will be readily understood that when the stove is in operation the product of combustion follows substantially the path indicated by the arrow 1 on Fig. 2, and that a current of air willbe drawn at the bottom of the circulating-flue, will be heated as itpasses through the sections F G, and will be discharged through the openings of the cover 01 into the surrounding apartment. With prop- IOC erly-fitted joints between the parts none of the products of combustion will be mingled with that heated column of air.

Of course a hot-air flue may be connected with this circulating-flue and conduct the heated air to an apartment above the one in which the stove is situated. 7

As will be seen, the section E of the air adjacent to and utilizing the heat from the firepot is separated from and-out of direct contact with the fire, thus preventing the beveling out of the walls of the said section and in no wise interfering with the use of a grate of any desired construction. 7 W

I deem it important that the section E be a part of the stove, and that the inner wall thereof be formed by the adjacent wall of the fire-chamber and base, thus effecting a saving of material and providing for the partial warming of the air in its passage through said section.

I claim- 1. In a stove, a circulating ail-chamber separated from and extending to a point over and above the fire-pot, the outer wall of the fire-pot forming the inner wall of the airchamber, substantially as set forth.

2. In a stove, a circulating air-chamberconsisting of a section E adjacent to and separated from the fire-pot by the fire-pot wall, which forms the inner wall of said section, a section G within the stove, and an inclined sect-ion F, connecting the sections E and G, substantially as described.

8. In a stove, a circulating air-chamber consisting of a section E exterior to and adjacent to the ire-pot, the wall of which forms the inner wall of said section, a section G within the stove-body, and an inclined section F above the fire-pot communicating with the section E through an opening in the said stove-body, and also connected with the section G, substantially as described.

l. In combination with a stove-body, an air-circulating chamber consisting of a lower section E, an upper section G, and an inclined section F, connecting the other sections, and having a flange c on one end and an enlarged part or collar on the other end, said collar and flange being at substantially right angles to each other, and supporting-rings for the sections F and G, substantially as described.

5. In a stove, the combination, with the cy lindrical chamber 0, of the top plate, the cover, and the ring D, interposed between the top plate and formed with depending flange and upwardly-exten ding flange 61 over which the outeredge of the cap fits, substantially as shown and described.

6, In a stove, the combination,witl1 the sectional cylinder 0, the top plate D, and ring D, having vertically-extending flanges, of the ring F and the rods 1) b, engaging said rings and serving to hold the rings and sections together, substantially as and for the purpose specified, 1

'7. In astove, the combination,with the cylinder C in sections, the top plate D, having central openings d and depending flange,

and the ring D, formed with the inner concentric ring d of the ring F, formed with the inner concentric ring f the upper section G of the circulating-flue held in said inner rings, and the rods 19 1), connecting the rings F and D, substantially as and for the purpose specified.
