Letters Patent N 107,394, dated September 13, 1870.

COOKING-STOVE.

T e Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern.-

Be it known that I, JAMES H. MCGONXELL, of Beaver Falls, in the county of Beaver, and State of Pennsylvania, have invented a new and useful Improvement-in Stoves; and I do hereby declare that the following is a full and exact description thereof, referencebeing had to the accompanying drawing and to the letters of reference marked thereon.

The nature of my invent-ion consists in so constructing a stove that its fire-back shall have an airchamber in the rear of it, communicating with a flue which passes over the top plate of the oven of the stove.

My invention also consists inproviding the fines of the stove with a damper or valve, so constructed that, when it has closed the most direct opening to the stove-pipe or chimney, there shall be a communication between the air-chamber in the rear of the fireback and the stove-pipeor chimney.

To enable others skilled in the art to makeand use my invention, I will proceed to describe more fully its construction and operation.

In the accompanying drawing my specification- Figure 1 is a vertical and longitudinal section of an ordinary stove provided with my improvement.

Figure 2 is a transverse section of the same.

Figure 3 is a face view of the damper or valve of the stove.

The stove represented in the accompanying drawing is of ordinary construction.

A represents its fire-back, in the rear of which is an air-chan'lber, B, which communicates with the flue O, which communicates with the pipe or flue S.

which forms part of The fine O is arranged on the top plate c'of the pivoted at the back end of the flue Q, between the flue-plates a.

"As the construction and arrangement of my improvement, with relation to'the ordinary cookingstove, will be readily understood from the foregoing description and by reference to the accompanying- .drawing, I will therefore proceed to describe its operation, whichis as followsi The air passes, at openings in the sides of the stove, into the chamber B, where it becomes heated it then passes into and through the flue G, into the stove-pipe flue S, and out through the stove-pipe or chimney; \Vhen the damper on is in the position turned up, as shown in figs. l and 2, then the" communication between the fines O and S is kept open by means of the opening a in the damperm. When the damper is up the heat and smoke will pass back and down the fiues land 1, and through the fines l to a very great degree, the fire-plate from burning out, and overheating the front and the central portion of the top of .the oven, equalizing the heat in all parts of it.

Having thus described the nature, construction,

and opera-tion of my improvement,

What I claim as of my invention is' .l. -Providing the air-chamber, back of the fire-plat of a cooking-stove, with a flue, which passes over the top'plate of the oven, as herein described, and for thc purpose set forth.

2. Combining with the above flue and air-chamber the damper an, arranged and operating substantially as herein described, and for the purpose set forth.
