T0. ctZZ whom, it may concern: Y

Be it known that 1, WILLIAM HEUERMANN, a citizen of the United States, residing at Sedalia, in the county of Pettis and State of Missouri, have made certain new and useful Improvements in Stoves, of which the following is a specification.

My invention is an improvement in stoves, having for an object, among others, to provide a novel construction whereby to secure the maximum heating results by means of a circulation of air and by the introduction of drum sections and tubes, as will be described; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a stove embodying my invention. Fig. 2 is a cross-section thereof on about line 2 2 of Fig. 1. Fig. 3is a vertical cross-section on about line 3 3 of Fig. 2, and Fig. tis a detail perspective view of the inner side of one of the hinged drum-sections.

In carrying out my invention I make the stove in two sections, an upper section A and the lower section B, the latter including the fire-box B, with its grate B and the firedoor B and the damper devices B opening below the grate 13 as will be understood from Figs. 1 and 2. The upper section A is preferably hinged at its rear edge at A to the upper edge of the section B, so the section A may be turned back on its hinge A to expose the entire interior of the section B and of the section A wheneverdesired. The section A immediately above the fire-box is provided with a tube D, extending from front to rear of the section A and opening at its ends to the atmosphere. This tube D may be made of any suitable cross-sectional shape, although for convenience in manufacture it may be preferred to make it round, as shown in Figs. 1, 2, and 3. This tube operates to secure good heating results by the circulation of the air from end to end and through the stove, and it also operates to throw the heat out next to the walls of the stove and adjacent to the inner faces of the opposite side flue-sections, presently described. At its upper end the stove is shown as rounded from front to rear and provided at its rear side with the offtake E,-which may be in the form of a nipple for the connection of a Stovepipe, as shown. A cross-flue F extends from side to side of the stove, is open at its ends where it abuts the drum-sections, presently described, and is provided inits lower side, practically in register with the otftake E, with an opening F, controlled by a damper or valve G, having a rod G extending outside the stove, so the damper G may be opened whenever it is desired to establish direct communication between the interior of the stove and the offtake E in the use of the invention.

The drum-sections II and I are arranged at the opposite sides of the stove and may, if desired, be hinged at one edge at H to the body of the stove and provided at the other edge with a latch H so the drumsections can be opened to permit access to the interior of the top section of the stove whenever desired. These drums have a generally circular form and round outwardly from their outer edges toward the center and are provided at their centers with the conical inwardly-flared radiating-surfaces hand 4I,which are in alinement and may be connected at their inner ends by means of a bolt J, as shown. The drum-sections H and I are substantially alike, being formed to provide a curved fiue having the inlet-opening h or t", the discharge-opening 71 or t' registering with the ends of the cross-flue F, said inlet and outlet opening being separated by partitions 72, or of, so that the hot air, smoke, 850., entering the openings h and 2" will be forced to travel around the drum-sections and discharge at 77. or 2' to the ends of the cross-fines F, as will be understood from Figs. 2, 3, and 4 of the drawings. Openings 77. and i may be provided between the inlet and discharge openings and cont-rolled by valves k and t to secure a quicker draft whenever desired, also for cleaning.

' In the operation of my invention it will be noticed the drum-tubeD in additionto heating the air which passes through it will force the heat out toward the inner sides of the drum-sections II and I, so the heat will be caused to pass to the inlet-openings of said sections and then around the drums and from the dischargempenings thereof to the ends of the cross-flue and thence out the ofitake, provided the dampers G, h and t are closed.

If the dampers 72 and are open, the heat will be caused to pass more directly to the dischargeopenings h and t", while if the damper G be open the heat will pass directly from the ofiftake. The conical or funnelshaped centers of the drum-sections operate in a measure as reflectors for the purpose of throwing out the heat and improving the results secured in the use of the invention.

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

1. The improvement in stoves herein described, comprising the lower section having the fire-box, the upper section hinged to the lower section, and provided with the drumtube extending from end to end and opening at its ends to the atmosphere, the olftake at the top of the upper section, the cross-flue below the oflftake and extending from side to side of the stove, and provided with a dam per in line with the oiftake, the circular side or drum sections having the central conical or funnel-shaped reflectors, and provided with the flues encircling the reflectors and having the discharge-openings in register with the ends of the cross-flue, and the inlet-openings adjacent to the discharge-openings and the partition crossing the flue between the said openings, and the rod connecting the said fluesections at the centers thereof, substantially as set forth.

2. A stove having a flue-tube extending from front to rear and open at its end and arranged to deflect the heat toward the sides of the stove, the drum-sections at the opposite sides of the stove and alongside the drumtube, and arranged to receive the heat deflected thereby, and provided with inlet and discharge openings, the cross-flue registering with the discharge-openings of the drum-sections, and the offtake, substantially as described.

3. A stove having a flue-tube extending through it and a drum section or sections to which the heat is deflected by the sides of said drum-tube, substantially as described.

4. A stove having the opposite drum-sections, provided with the central conical or funnel-shaped reflectors and with the fines snrrounding the same, and having inlet and discharge openings leading to said flue, substantially as described.

5. The combination in a stove, of the stovebody having the cross -flue, and -the olftake communicating therewith, and the opposite drum-sections having the funnel-shaped refiectors, and the fines surrounding the same, and the rod connecting the inner ends of the funnel-shaped reflectors, substantially as set forth.

6. The combination of the stove-body, the fine-tube extending from front to rear thereof and open at its ends, and the drum-sections at the opposite sides of the stove and on opposite sides of the flue-tube, and having the funnel-shaped reflectors extending at their inner ends above the flue-tube, and connections between the inner ends of the funnelshaped reflectors, substantially as set forth.
