SAMUELS. WALES, OF MINNEAPOLIS, MINNESOTA.

HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 408,773, dated A ugust 13, 1889.

Application filed July 26, 1887- Serial No. 245,309. (No model.)

Be it known that I, SAMUEL S. WALES, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and-useful Improvements in Heating- Stoves, of which the following is a specification.

My inventionrelates to certain improvements in heating-stoves5 and it consists, generally, in the combination and arrangement hereinafter described, and particularly pointed out in the claims.

In the drawings which form a part of this specification, Figure 1 is a front elevation of my improved stove. Fig. 2 is a vertical crosssection of the same. Fig. 3 is a vertical longitudinal section; and Fig. 4 is a detail.

The lower portion of the stove is constructed in the ordinary manner, having the fire-pot 2 and grate 3, and ash-pan 4, made after any well-known pattern of heating-stoves.

6 is a ring or band, preferably of cast metal, which fits the upper rim of the fire-pot and may be made either round or square to suit the style of stove. Upon the upper surface of this rim I prefer to provide two sets of flanges, the flange 7 at the inner edge or around the opening in the rim, and the flange 9 at or near the outer edge.

10 is a combustion-chamber, consisting preferably of a sheet-metal drum that is placed above the fire-pot and rests upon the top of the rim 6, just within the flange 7. This combustion-chamber is closed at the top and provided with a smoke or draft pipe 12.

14 is a drum, preferably formed of sheet metal and extending over the combustion chamber and resting upon the rim 6, just within the flange 9,leaving an annular space between the drum and the combustion-chamber. An inlet-opening 18, covered by a suitable damper, is formed near the bottom of the drum to provide for the admission of the outside air. at the top of the drum, and pipes may be placed over these openings and the heated air from the drum conveyed to other rooms.

22 is a fuel-door in the wall of the outer drum or casing surrounded by a chute 23, extending from said door across the annular space between the drums and opening into the combustion-chamben The fuel may be the top of the combustion-chamber.

Outlet-openings 20 are provided fed through this door and chute into the firepot.

The inner drum, forming the combustionchamber, is preferably of considerably less height than the outer drum, so that an airspace of considerable size is provided above The inner drum is also preferably provided with a flat top and the outer drum with a door 16in its wall nearly opposite this top, so that the chamber above the inner drum is adapted to be used as a heating-oven. By opening the door 16 articles that it is desired to heat may be placed in this chamber on the flat top of the inner drum. The chamber thus serves the double purpose of a heating-oven and an air-heating chamber, fromwhich the air after being heated may be conveyed to any desired point. The annular space between two drums forms a continuous air-heating flue, into the lower part of which the air is admitted through the draft-openings 18, and wherein it is raised to a high temperature as it passes up over the wall of the inner drum or combustion-chamber. The smoke-flue preferably passes out at the top of the combustion-chamher and passes through the heating-chamber, so that the heat radiated from it aids in increasing the temperature of the air in this chamber. chamber may be used in connection with any kind of stove, self-feeder, base-burner, &c. The construction is verysimple and inexpensive.

The base of the stove radiates heat to the This arrangement of the heatingroom in Which it is loeated,while the heating- 1 drums, without lessening the radiating effect of the base of the stove, in addition heat a large supply of air which may be thrown out into the same room or conveyed to other rooms of the building' I claim as my invention- 1. In a heating-stove, the combination,with the base 2, constituting a surface for directly radiating heat into the room, of the rim 6,

inlet 18 in its side above the base and rim 6 and opening into the space between the two drums and provided witha closed top having exit-openings 20 for the attachment of conducting-fines, and having a door 16 above the flat top of the inner door, all substantially as and for the purposes set forth.

2. The combination, in a heating-stove, of the fire-pot 2, the rim 6, fitted to the top of said fire-pot and projecting inwardly over the chamber of the same and formed with the flanges 7 and 9, the drum 10, having a closed top and resting on said rim next to the flange 7, the drum 14, resting on said rim next to the flange 9 and provided with inlet-openings 18
