TO ALL WHOM IT MAY CONCERN:

Be it knownv that I, GEORGE W. BERD, of the city and `county of Baltimore, in the State of Maryland;`il`

have invented certain new and useful improvements in Stoves; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, the figures and letters indicating the several parts as follows:

In Figure 1, A is the air-'heating chamber; B the inside tine; D the lower chamber; F the hre-flue; G the coal-flue or feeder; L the4 opening through which the air is to pass from' the lower to the upper chamber; and the arrow indicates the direction of the air from the bottom.

In Figure 2, E is a cast-iron bottom; F is the fire-flue; and K isa collar through which the air enters the heating chamber. i i

In Figure 3, the black lines represent the air-heating chamber; the red lines the stove; and the `dotted lines theframe and casing around the stove. C represents the chamber, of two and a half inches; H; collars;

I, collars between the twovvre-chambers; J, the stove pipe; M, the cast-iron rin or top; O,othe space irl-which the re acts on the stove and chamber.

In Figure 4, P represents the sliding-bars of the rake; R, the teeth-bar; and S, the handle.

In Figure 5, P represents the sliding-bars of the grate; and T, the bars.

In Figure 6, K shows where collar K in iig. 2 is placed.

The nature of my invention consists in constructing and adapting to a Stove a heating chamber of peculiar construction; also, in the construction and adaptation to a furnace of an improved rake.

To enable others to make and use my invention, I will proceed to describe its construction and operation,

I make the stove, furnace, or heater, upright and cylindricalln any of the known forms, and apply thereto an inner double cylinder, say fifteen inches high, eleven inches in diameter, and with a luel-in the centre six inches in diameter, forming a chamber two and a halt' inches between the eleven-inch cylinder and six-inch' flue. Ten inches from the top there. is a bottom with an opening in front, (as'seen in lig. 1,-letter I of onethird the circumference, for the purpose of letting the air pass from the lower chamber l). Five inches below, I place another bottom of cast iron, (as sehn in iig. 2, letter E,) forming a chamber of two and a half by' four and a half inches around the sixinch flue, with the collar attached, (lette'r IQ) through which the air is admitted from the bottom of the stove into the heating chamber. When the air passes through the collar K it passes t`o the right and left, (as seen by the ari'ows in fig. 1,) into the upper chamber at letter Ii', and thence up the chimney-flue to the register.

Having described the air-heating chamber, I will proceed to de`scribe how it is placed in the stove and the action of the fire thereon. i

The rim or top M is one and a quarter inch in width, with a ange on the outside one-half an inch in depthto tit inside the stove cylinder. This rim should be of cast iron to support my heating chamber in its place, and also to close the top oi' space O, (in ig. 3,) in which the re has a direct action on the stove and on my heating chamber. Through this space O the smoke passes, and escapes, through the collar II, into the oval column, as seen on each side of the stove. The tire has also a central action in the heating chamber, entering the iue B at F, (as seen in iig. 1,) and through which the smoke passes through collar I, (as see`n in iig. 3,) into space O, then into collars H as above. ,Flue B is enclosed with a movable top, N.

Isliall now give a description of my improved rake and its operation. It is constructed with a bar, R,

(fig. 4,) withlteeth placed therein, so that there will be a tooth at cach opening of the grate, as in iig. 6; also,

two sliding-bars P on the back, with a handle, S, in front, whichis moved as a piston through ears I on the rear of the grate.

For the purposes I h'avein view, a stove, afurnace, and a heater may be regarded as equivalent terms; and I claiml. In combination with a stove, an air-heating chamber, constructed and arranged substantially as described.

2. In combination withthe foregoing, a grate, with the rake S R constructed and operating substantially as described.

GEORGE W. BEARD.
