IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 44,449, dated September 27, 1864.

To all whom it may concern Be it known that I, P. P. PARKHURST, of

Milford, in the county of Worcester and State of Massachusetts, have invented a new and Improved Stove; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, making a part of this specification, said drawin g representing a vertical central section of my invention.

The object of this invention is to obtain a stove which will radiate the heat into the compartment in which it is placed by withholding the products of combustion within a chamber above the fire-pot, so that they cannot pass directly into the flue, and having said chamber communicate with the fire-pot by means of a series of tubes, which form in the aggregate a large radiating-surface. The stove is also provided with a pipe arranged in a novel way to afford the necessary draft.

A represents the fire-pot or fire-chamber of the stove, which rests upon an ash-box, B, and is provided with a grate, O, at its lower end.

D representsa series of vertical tubes, which form a communication between the fire-chamber A and a drum or hotair chamber, E, which is some distance above the fire-chamher A.

F isa pipe, which extends vertically upward from the center of the hot-air chamber E,and is provided with two dampers, G G.

H Hare two pipes, which extend upward from opposite sides of the fire-chamber A at the top of the fuel therein, and communicate with the pipe F, between the two dampers, G G, as plainly shown in the drawing. When a direct draft is required, as in kindling the fire, the dampers G G are opened and a strong draft obtained. By closing the lower clamper, G, the gases are retained in the drum E, which is a hot-air chamber, the tubes D serving as radiators. By closing both dampers G G an air-tight stove is obtained and a very slow combustion allowed to proceed in the fire-chamber A. By this arrangement I obtain a radiating and an air-tight stove, and one which may be economically constructed, and a great amount of heat radiated into the room from a given quantity of fuel.

1 claim as new and desire to secure by Letters Patent- The series of tubes D, communicating with the tire-chamber A, and drum or hot-air chamber, E, in connection with the pipes H H F and dampers G G, all arranged substantially as herein set forth.

P. P. PARKHURST.
