IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 122,160, dated December 26, 1871.

rora, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Heating-Stoves; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which-- Figure 1 is a sectional front view of a heatingstove made with my improvements. Fig. 2 is a vertical central section of such a stove taken from front to rear; and Fig. 3 is a horizontal section of the same on line y y.

Like letters indicate like parts in each figure.

To enable those skilled in the art to make and use my invention I will proceed to describe the same with particularity, making use in so doing of the aforesaid drawing.

In the drawing, A represents the grate or fireplace, the exit from which is by way of the throat or passage a. The hollow diaphragm B, standing at an incline across thisthroat, causesthe escaping products to be deflected over the burning coal;

also more effectively radiating the heat to the front of the grate; and, by reason of numerous holes I) in its outer edge, causing a supply of warm air admitted through the pipes G to mingle with the passing gases to produce a more perfect combustion. D is a radiating-chamber which surrounds the grate upon the top and three sides.

The products of combustion passing the throat a find their way directly into this chamber. E is a pendent vertical pipe or flue open at the bottom, and opening also into the small chamber I, which communicates directly with the exitflue G. H is a damper contained within the chamber F, and so hinged as to cover the mouth of the pipe E when lying in a horizontal position;

but when raised to a vertical position disclosing said pipe and closing an aperture, J, in the chamber F communicating from the radiating chamber. When a direct draught is desired to fan the fire in kindling or for other reason, the aperture J is opened and, by the same movement, the pipe E is closed. The draft is now directly from the throat a through the aperture J and chamber F, to the exitfiue. On the other hand, if the heat is desired the aperture J is closed and, by the same movement, pipe E opened. The current is now reverted, the hot air, by reason of its rising tendency, fills the entire radiating-chamber, and, after parting with its heat, is impelled by gravity to the bottom of the pipe E, and is finally forced out through the same into the chamber F and out The damper H is mounted upon a shaft, h, which passes out to a position convenient of access outside of the stove. K is a dust-damper or door leading from the back part of the ash-pit into the bottom of the radiatingchamber, and should be opened when cleaning the fire, when the draught will carry the dust and ashes into the chamber and up the flue, and thus prevent them from getting into the apartment.

The radiating-chamber and its attachments may be built into the breast of a chimney behind the grate and surrounded by a chamber having air-inlets at the bottom and exits at the top, through which latter the air heated in its pas sage through said surrounding air-chamber-is discharged into the apartment.

What I claim as my invention, secure by Letters Patent, is-

The combination and arrangement of the radiating-chamber D, the pipe E, chamber F, and

and desire to damper H, substantially as specified and shown.
