Letters Patent No. 104,269, dated June 14,1870.

COAL-STOVE.

The Schedule rei'eiredto in these Letters Patent and making part of the same To all whom it may concern Be it known that we, Du Wrr'r O. CLARKalld HEN- RY W. CADY, of Sioux City, in the county of Woodbury and State of Iowa, have invented a new and use,- i'ul Improvement in Stoves for Heating Purposes; and

.we do hereby declare that the following is a full, clear,

iuent in heating-stoves, whereby such stoves are ren-' dered more eiiicientv for the purpose intended than stoves of ordinary construction, and

It consists in forming chambers between the outer wall or casing of the stove and the lining, and in a damper inthe lining, and a dividing partition, as hereinafter more fully described.

In the accompanying drawing- Figure 1. represents a' vertical section of a stove constructed according to our invention, the section being; through the line a; a: of fig. 2.

Figure 2 is a horizontal section through the line 3 y of fig. '1.

Similar letters of reference indicate corresponding parts."

A is the outer wall or casing of the stove.

B is the-lining.

O is an air-chamber immediately surrounding the fire-box or furnace of the stove. Air is admitted to thischamber through the damper D.

' E is a damper in the lining B, which is opcrat ed by means ot the rod F. The damper D works onthis l0d+ By this arrangement a current of air may be carried directly into the stove and in contact with the. fuel,-

whichmay be of advantage inlstartiug a fire, but ordinarily the air for the support of combustion is admitted from the chamber Gthrough a series of holes This chamber H receives air from the outside through a series of holes, J, through the cylinder or casing A, just above the partition I. The air which enters this chamber is discharged from apertures, L, through the top Kof the stove, which apertures communicate with the chamber.

' In this manner, air which has entered the chamber above thcfire-hox is heated and discharged into the room at the top of the stove. The current which enters the chamber 0 through the damper for the support of combustion may be cut off, or nearly cut off, after the fire has been well started, so that, by this arrangement, there will be a constant flow of heatedaii" The air necessary for combustion will into the room. he introduced, while the disagreeable current of cold air on the floor toward the stove will be avoided. The latter inconvenience is felt in all cases when heatingstoves receive their air'at the bottom, as is usual.

- M is the door for the introduction of the fuel.

N is the smoke-pipe.

O is a cover over an aperture in the top of the stove.

These stoves may be made either round. or oval, andare adapted for either wood or coal.

By admitting the air upon all sides of the fuel, through the orifices G, a more perfect and economical combustion of the fuel is produced than by the ordinary method. 1

Having thus described our invention,

We claim as new and desire to secure by Letters .Patenty 1. The damper E in the lining B of the stove, arranged to operate substantially as set forth.

2. In combination with the chamber C and H, the partition I, by which the two chambers are separated. arranged substantially as described.
