COOKING-STOVE.

Specification of Letters l atent No. 7,459, dated June 25, 1850.

To all whom it may concern:

Be it known that I, ABRAHAM KEAGY, of Middle lVoodbury township, in the county of Bedford and State of Pennsylvania, have invented certain Improvements in Cooking- Stoves, and that the following is a full, clear, and exact description of the principle or character which distinguishes them from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure 1 is a perspective view of the stove with the back plate removed. Fig. 2 is a section through the flue (g) and Fig. 3 a section through the flue (h). Fig. 4, is a view of the damper.

My improvements consist in so constructing the stove that the flue instead of conducting the flame and hot air from the fire firstly around the back and under the bottom of the oven and then either returning under the bottom and back, or else having to cross itself after passing over the top of the oven, through a box. It makes the hot air after passing to the back of the fire to return between the fire chamber and the top of the oven, and thence around it, by the front, bottom and back, to the chimney, or if required it can be made to pass twice around the oven before entering the chimney.

The stove is made in the common form, having the oven (at) underneath the fire chamber (7)) and the chimney (0) at the back. When the damper (d) is open the heat passes directly up the chimney, but when it is closed, and the damper (a) open as in Fig. 3 the heat has to pass around the plate (f) over the top of the oven, through the fines (g and h) in the direction of the arrows and from thence up the chimney.

Thereby enveloping the whole surface of the oven, and circulating once around it. When the damper (e) is closed as in Fig. 2, the heat has to pass around the oven, firstly through the flue (g) which is separated from the fine (it) by the partition (is) from thence it passes by the aperture (2') in the partition (70) into the flue (lb) and then has to pass a second time around the oven before it can make its escape by the chimney. It will be readily seen that by this arrangement I effect a great saving of fuel by causing the heated gases to traverse such a long and circuitous passage, and the oven being separated from the fire chamber by a stratum of air, is less liable to scorch its contents by being too intensely heated in any one part.

The axis of the damper (e) is on the line of junction of the back and top flues. There is a projection (e) upward from this axis on one side of the center line of the stove sufficient to cover the opening into the flue (h) and in the same plane a projecting plate (6") extends downward sufficiently to close the back flue (g) at the same time the other projection closes the flue (h). And when the flue (h) is opened by turning the damper this lower portion (6) closes the opening between the top andback flue.

Having thus fully described my improve ments in cooking stoves, what I claim and desire to secure by Letters Patent is- The combination of the flues with a single damper (6) so that by a single movement I cause the hot air to traverse once or twice entirely around the oven at pleasure, substantially as described.
