SPECIFICATION forming partof Letters Appiimion inea Julyi, 189s.

-Be it known that I, WLLIAM' H. JAMES, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in food Burning Stoves; and I do hereby declare lthe followof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in wood-burning stoves, and more particularly to the stove shown in Patent No.. 600,248, granted me MarchS, 1898; and it consists in the parts and combinations of parts, as will bemore fully described, and pointed out in the claims. v j

In the accompanying drawings, Figure l is a view in transverse vertical section of my improved stove. Fig. 2 is a view' in longitudinal vertical section. Fig. 3 isa horizontal sectional view. Fig. 4 is a detached view of a portion of the inner casing or tire-pot, and Fig. 5 is a view of a modiiication.

In the stove shown in my Patent No. 600,248 the outer casing is angular and the inner casing or iire-pot curvilinear in-horizontal crosssection, the sides of the inner chamber or firepot being parallel with the sides of the outer casing, thus forming enlarged air-spaces at the angles of the outer casing and-greatlyrestricted spaces at points intermediate the angles.

In my present invention I have employed a re-pot curvilinear in vertical cross-section and located horizontally Within the angular jacket with its ends adjacent to the front and` rear of the jacket and with its curved sides presented toward the bottom sides and top of said jacket. f

A represents the outer jacket, open at its lower end andv preferably rectangular longi tudinally and square transversely. This jacket is mounted on legs a, which latter are secured to the lowerend of the jacket, at the angles thereof, and hence elevate `the lower open end of the jacket above the floor.

B represents the sheetmetal.fire-pot,located within and wholly supported bythe jacket. This tire-pot has iiat ends b and c, which latter rest in close proximity to the front and Patent No. 629,191, dated July 1s, 1899. serai no. 686,126. (Nc man.)

rear faces of the, stove, While the bottom, top, and sides of the tire-box are curved. This fire-pot can be of oval or cylindrical shape in transverse vertical cross-section with the centers d of its curved sides in close proximity to the sides of thejacket, thus forming restricted passage-ways through which -the hot air must pass. Viithv this construction it will be seen that the side passages for the air are 6o enlarged at the extreme bottom of the nre-pot, thus accommodating a large volume of air,

and as the base or bottom of the fire-pot is curved it presents a much greater heating and radiating surface than the flat-bottom repot ofmy patented device. j The air as it eni ters or passes yunder the jacket is heated, and as it becomes heated it rises. As it rises through the gradually-converging air-passages at the sides the heat becomes more in- 7otense and the upward movement morerapid until the air passes the most restricted portions of the passage. By this construction ample space for the reception of the heated air is provided above and at the sides of the re-pot and for the cold air at the base of the fire-pot. y

The top ofthe jacket is provided with perforations e for the free escape of the lhot air, and it may also, if desired, be provided at its 8o top with an opening f, surrounded by a collar g. This collar may form a seat for a perforated hood E, ory it may be used for the attachment of a hot-air pipe leading to a drum or register in a distant portion o f the house, S 5 as shown in dotted lines, or it may be a fuelopening, as shown in Fig. 5. Y

As shown in Fig. 5, a collar h connects the top of the jacket and the re-pot',.theflatter .being openfor the free introduction ofthe 9o fuel. I prefer, however, to locate the fueldoor at the front, as shown in Figs. 1 and 2, and When so located the front flat end of the fire-pot is slitted, as shown vin Fig. 4, to form the four flaps F.y These flaps are then turned outwardly at right angles to the front face of the firepot and again bent inwardly, as at h, toward each other and parallel to the front face ofl the` ire-pot. Thelips hrest againstthe rearface of the jacket adjacentto the 10o fuel-opening therein, `and the door-frame, jacket, and lips 71, are secured together by bolts. The openings at the `four corners, caused by bending the iiaps outwardly, are closed by the angle-plates H, which latter are secured to the iiaps by bolts or rivets.

By employing an angular jacket and a curvilinear fire-pot so located With relation to each other that the side passages for the air are restricted at their centers and enlarged at both extremities the large volume of air at the lower ends of the passages moves upwardly slowly at the start, and hence is subjected for a longer period to the heat, and increases its speed as it passes upwardly. After passing the restricted centers, Where the heat is the greatest, the passages again expand Y and permit of the free and rapid expansion of the highly-heated air.

Air of course passes up between the ends of there-pot and adjacent faces of the jacket; but the greater volume passes up between the curved sides of the hre-pot and the sides of the jacket.

It is evident that many slight changes might be resorted to in the relative arrangement oi' parts herein shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not restrict myself to the exact construction of parts shown and de,- scribed; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

2. In a Wood-burning heating-stove, thel combination of an outer jacket angular in cross-section, open at its bottom and provided with air-escape opening in its top, a irepot having vertical ends, and located within said jacket, the front end plate of the lire-pot being slitted to form four flaps Which are bent, irst at right angles to the end plate forming flaps and then toward each other forming lips, angle-plates connecting the flanges at the angles or corners and devices for securing the lips to the jacket.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
