H EATING-STOVE.

lsrEcrrIcA'rIoN forming part of Letters .Patent No. 747,674, dated December 22, 190s.

Application filed June 1,1903. `Serial No. 159,480. (No model.)

To all whom t may concern.-

Be it known that we, HENRY BEACH, a resident of Carthage, in the county of Hancock, and JAMES B. COE, a resident of Clayton, in the county ot Adams, State of Illinois= citizens of the United States, have invented new and useful Improvements in Heating-Stoves,

of which the following is a full, clear, and` exact description.

This invention relates to improvements in heating-stoves of the base-burner type in which bituminous or other coal is used as fuel, an object being to so construct a stove that the evolved gases are driven through the live coals in the tire-pot into the space below the same, where the gases are burned to give out heat instead of consuming the gases in the fire-pot. By thisfarrangement we find that such perfect combustion is attained that there are practically no cinders, and smoke and soot are practically eliminated, resulting in economy of fuel.

Other objects of the invention will appear in the general description.

We will describe a heating-stove embodying ourinvention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a sectional elevation ofa heatingstove embodying our invention, and Fig. 2 is alsection on the line new of Fig. 1.

Referring to the drawings, 1 designates the ash pit or box, having a'door 2 for its opening, and above this ash-pit is the base or combustion-chamber, consisting ot the bottom wall 3, the surrounding wall 4, and the top wall 5. arched ring and is quite thick, which gives it the necessary strength to support the base mounted thereon. The combustion-chamber communicates through a flue 6 with an uptake 7, and arranged in the base and extending partly around the same `is a cold -air chamber having spaced side walls 8 9, and there is a space between the wall 9 and the wall 4 of the combustion-chamber or base. The bottom wall 3 of the base is provided with perforations 10 to admit air into the cold-air chamber, and this air passes out This top wall is in the form of an.

through perforations 11 in the top wall or ring 5. This double wall-flneor air-chamber gives more radiating-surface and at the same time exposes one surfaceto the air for protection.`

Supported on the`top or ring 5 is a re-pot l2. This tire-pot 12 is seated on a ring 13,

. which engages directly with thering 5, and this ring 13 is made heavy, so as to' withstand heat, and it is provided with vertically-disposed ngers 14, through the spaces between which the gases may pass to the base. On the top of the tire-pot section 12, it being nnderstood that the part 13 is practically a continuation of the tire-pot, is a dome-shaped ring r15, provided with perforations 16, and extended upward from this dome -shapedring 15 is a magazine 17, from which the fuel passes to the fire-pot.

Supported by the dome-shaped ring 15 andsnrrounding the magazine is an air-drum 18, from one side of which a damper-flue 19 extends outward, and at the other side a flue 20 connects said drum with the uptake 7. In this flue 20 is a damper 2l, which is designed to be closed when the tire is well under way. The damper for the flue 1'9- consists of a plate 22, movable outward and inward at the outer end of said flue. The plate 22 is provided at its center with a socket member 23, in which a ball member 24 is arranged to swing, and

rod 25, having a shoulder 26 for engaging with a lug 27, extended inward from the wall of the fiue'l9. Attached to the inner side of the flue 19 near'its outer end is a ring 28, provided with perforations through which guiderods 29 may move. The outer ends of these guide-rods are connected to the damper-plate 22, and the inner ends are connected to a ring 30, slidable in the fine. By this arrange- 4ment it is obvious that by releasing the shoulder 26 from the lug -27 the damper may be moved outward, so as to admit air to the airdrurn, and it may be held closed by engaging. said shoulder with the lug.

To give additional supporting strength, there are bracket connections 31 between the wall of the ash-pit and the bottom wall 3 of the base or combustion-chamber.

Supported by the base and surrounding the ICO provided with variously-placed openings 33, through which hot air may readily pass. The top opening of this shell above the magazine is provided with a door 34. Below the'trepot is a concaved or dish-shaped grate 35, having radial fingers 36, through the spaces between which gases may pass to the combustion-chamber. This grate is attached to a pedestal 37, supported by crossed bars 38, attached to opposite walls of the ash-pit. This pedestal 37 is rectangular in cross-section, and the crossed bars 38 have at the center an opening' 39, which is similar in shape and size to the pedestal. The pedestal near its lower end has a reduced portion40, providing shoulders for engaging, respectively, on the upper and lower sides of the crossed supportingbars 38. To lower the grate when it is desired to clean out the fire-pot, it is to be turned, so that the pedestal may readily pass through the opening 39. It will then drop until its lower end engages the bottom wall of the ashpit. Of course in replacing the grate it is to be raised and the pedestal given a onequarter turn to cause the shoulders to engage with the crossed bars 38, as indicated in the drawings.

In the operation when starting a fire the damper 2l is to be opened and the damperplate 22 closed, so that a draft may be created upward through the tire-pot. When well started, the damper 2l is to be closed and the damper-plate 22 opened, and then atmospheric air will pass into the drum 18 and thence through the perforations 16 through the burning coal. The dome-shaped ring 15 will cause the air to be spread and pass down the inner side of the tire pot wall. The evolved gases will be driven through the live coal, Where they become ignited. Very little Haine or heat takes place in the tire-pot, the gases being almost entirely consumed in the base. Whatlittle product may remain passes -out between the walls 4 and 9 to the uptake. Atmospheric air will pass through the colda-ir chamber through the perforations l1, and in passing through said cold-air chamber it will become heated and will pass out through the distributing-openings 33 of the shell. As practically al1 the blazing flame is in the base the ire-pot or fuel-pot 12 has more room for fuel than is the case when combustion takes place in the tire-pot.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- l. A heating-stove comprising a combustion-chamber having a ring-like and arched top, an air-box extending partially along the chamber, the said top having perforations communicating with the box, and the bottom of the box also having perforations communicating with the box, a shell supported by said top wall and having openiugs, a fire-pot supported on said top, an arched ring forming the top of the re-box and having perforalions, a magazine extended upward from said arched ring, an air-drum surrounding said magazine and supported by said arched ring, means for controlling the admission of air to said drum, a damper-controlled outlet for said drum, and a grate arranged below the fire-pot.

2. A heater comprising an ash-pit, a combustion-chamber above the ash-pit, a tire-pot above the combustion-chamber and having vertical corrugations at its lower end, a magazine communicating with the repot,means for directing air into the tlre-pot, and a concaved or plate-like grate arranged u nderneath the fire-pot.

3. In a heater, an ash-pit, a combustionchamber comprising a bottom wall extended outward from the upper end of said ash-pit, brackets connecting with the ash-pit and said bottom wall, a tire-pot supported 0n the upper Wall of the combustion-chamber, supporting-bars extended across the ash-pit, and a grate removably supported on said bars.

4c. The combination with a base-burning heater, of a fire-potsupported therein, a ringlike and arched top for said fire-pot, the said top having perforations, a magazine supported by said top, an air-drum surrounding the magazine and supported by said top, a damper-flue extended outward from said drum, a plate-like damper for engaging against the end of said flue, a perforated ring secured within the Hue, a ring movable lengthwise of the flue, guide-rods attached to said movable ring and passing through perforations in the first-named ring and connecting with the damper-plate, a lug arranged in the flue, and a latch-rod having swinging connection with the damper and adapted forengagement with said lug.

In testimony whereof we have each signed our names to this specification in the presence of two subscribing witnesses.
