H EATING-STOVE.
SPECIFICATION forming; part of Letters Patent No. 736,740, dated August 18, 190B. Application filed March 30,1903- Seral No. 150,173. (No model.)
T0 all whom/ t ntcty concern.:
Beit known that I, CHARLES J. KIRCH, a citizen of the United States, residing at Keokulr, in the county of Lee and State of Iowa, have invented certain new `and useful Improvements in Heating-Stoves, of which the following is a specification.
This invention relates to heating-stoves and furnaces.
The object of the invention is to produce a stove or furnace of sim ple construction which shall be habitually a downdraft-stove, but which can be used as anupdraft-stove for purposes of ignition orotherwise, and-in which the air for the downdraft shall have been heated before it is fed to the fire. i
The invention consists in constructions and combinations of elements hereinafter pointed out in the claims.
Figure 1 is a vertical central section of the stove through the plane of the door and smokestack. Fig. 2 is a section on line 2, Fig'. 1. Fig. 3 is a front view'of the stove-body on a reduced scale. Y
The stove-body 1 is preferably of cylindrical form, as shown, and contains a fire-pot. 2 of common construction, preferably tapering. Below the fire-pot is an ash-pit 3, from which ashes may be removed as usual. The base of the fire-pot is supported by a partition 4, which partition is nearly cylindrical in form, but at the front side of the stove curves outwardly and is joined to the body 1. This partition has openings 5 at each side of the fire-door a and below the nre-pot. The stove-body has an opening at the backside below the fire-pot, and a flue 7 covers this opening. The flue 7 is preferably a crescentshaped sheet of metal attached at its edges to the outside of the stove-body. The stovebody also has an opening Sinto the iiue above the {jre-pot, and this opening may be closed by damper 9. A
At the front of the stove, extending through the base 10 and alongside the body 1, are two pipes 11, which are open below and open above into an outside air-chamber 12. This chamber has an opening or passage 13 into the stove-body above the lire-pot, and suchv opening can be closed by the sliding damper 14.
`The fire-door is suppliedrwith a suitable damper or draft-controller 15, as is usual. Fuel is introduced at the top of the fire-pot in convenient manner, as by removing the covers 17 and 18.
In starting a iire the damper 14 is closed and the damper 9 opened, and the fire is ignited from below, as is usual in updraftstoves, Aair being supplied Ithrough the door. `When the fire is well burning, damper 9 may be closed (as well as the damper 15) and damper 14 opened. The air-supply is then through pipes 1l, cold air being taken in at the bottom of said pipes and this air becoming heated as it rises in the pipes, and so this air entersthe body of thestove above the fire-pot already well heated, entering through the opening 13. The direction of air-currents are thence indicated by arrows. Air passing down through the iire-pot enters openings 5 and passes around the stove toward the rear, being in contact with the outside of the fire-pot between said fire-pot and the body 1 of the stove. The hot air and products of combustion escape from the nearly annular chamber 2O into the tiue 7, and so pass to the chimney `or smoke-stack.
The air of the room in which the stove is VVlocated is heated byradiation only. The
pipes which conduct the air to the stove for downdraft purposes being external form no obstruction to the circulation of air and gases within the stove, yet the air within such pipes is thoroughly heated before it reaches the re.
To protect the grate from excess of heat, I arrange pipes 30 in the side or sides of the stove. Pipe 30 is preferably a pipe extending through the side of the stove and turned up just below the grate, the upper end being closed to prevent ingress of ashes and the sides of the upturned portion perforated to permit escape of air. The inflow of air through these pipes prevents the heating of the grate to such a temperature as would be destructive while not preceptibly interfering with combustion.
What I claim is* 1. In a stove, the combination of a cylindrical shell or body, a tapering fire-pot within the same, and tting said stove-body at its upper end, a nearly cylindrical partition be- IOO low the fire-pot, and passages through this into the stove-body above the fire-pot, and a partition so that air entering the space bedamper controlling said opening. 2o tween the partition and shell may surround 4.

The combination of a cylindrical body, body and leading into the stove-body above tapering fire-pot, and nearly cylindrical parthe fire-pot, an annular chamber surrounding ition supporting the fire-pot, of a flue outthe fire-pot, a passage for hot air from below 25 side the stove, a passage through the parthe fire-pot leading to this chamber, and a tition below the fire-pot and a passage from smoke-flue outside the stove-body communi- Io the annular space about the fire-pot to the eating with the annular chamber below the outside lue which extends up alongside the fire-pot, all combined.
