Description
UNITED sTATEs PATENT oEEi'cE.
CHARLES B. SAVYER, OF IVITCHBURG, MASSACHUSETTS.
e AIR-HEATING STOVE.
Specification of Letters Patent No. 17,750, dated July?, 1857.
To all whom it may concern:
Be it known that I, CHARLES B. SAWYER, of Fitchburg, in the county of I/Vorcester and State of Massachusetts, have invented a new and useful Improvement in Air-Heating Devices for Buildings; and I do hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the annexed drawings, making a part of this specilication, in which- Figure 1 is a vertical and central section of my improvement. Fig. 2 is a horizontal section of'ditto; (x), (x), Fig. 1, indicating the plane of section.
^ Similar letters of reference indicate corresponding parts in the two gures.
This invention relates solely to an improvement in an air-heating device formerly patented by John Sawyer, in which a ventilating chamber, hot-air flue, smoke flue, and air-heating chamber are arranged and combined in a peculiar Way for effecting the desired purpose.
To enable those vskilled in the art to fullv understand and construct my invention, I will proceed to describe it.
A, represents an air-heating chamber which may be of cylindrical or other prop-pr form; and B, represents a stove placed wit the chamber A, said stove being provided with a smoke ipe (a), which passes up ver'- tically througiij the chamber A.
C, represents a cooking stove which may be placed outside the chamber A; the pipe (b) of said stove passing into or communieating with the stove B, or its pipe. The stove B is merely an auxiliary, and when not needed, as in summer, may be removed. The cook stove being always in use, remains stationary; its pipe (b), when the stove B is' removed, being connected directly with the pipe (a). E
D, represents a pipe which commumcates with the lower part of the chamber A. This pipe communicates with the external air or atmosphere.
In the u per part of the chamber A a Y small cham er E is placed, and this chamber E communicates with the chamber A by an openg (c) which is provided with a damer a hot-air flue F is placed, and the lue F is encompassed by a Ventilating chamber G. The smoke pipe (a) passes through the center of the hot-air flue F, and terminates in a small chamber H, placed over the hot-air On the upper part of the chamber iiue F and Ventilating chamber G. The hot I, represents hot-air pipes which lead from l the hot-air ilue F to the rooms to be heated.
J, represents a Ventilating pipe. a pipe J leading from each room into which hot airis conveyed by a pipe I. These pipes communicate with the lower part ofthe ventilating chamber G.
K is a pipe which passes through the ventilating chamber G. The lower end of this pipe communicates with the atmosphere, and the u per end passes into one of the rooms to be ieated. There is also a pipe K leading into every room to be heated. Vithin the chamber H a lamp L is placed. Each of the pipes I, J, K, is provided with a damper (7L), and each damper has a chain (i), the chain being placed within the pipes and leading into the rooms with which the pipes communicate.
The air-heating chamber A is placed in the lower story of a building, and the pipes I communicate with the several rooms to be heated as also the pipes J, K. The cold air passes into the chamber through the pipe D and becomes heated in passing u through said chamber into the hot air ue F, and the heated air passes into the several rooms through the pipes I. The air within the chamber G is rareied by the heat from the hot air ilue F, and the cold and vitiated air from the lower part of the rooms will pass through the pipes J into the chamber G and up through the chamber H into the pipe (g), the damper f being open. It will be. seen therefore that a circulation of air is ke t up in each room, warm air entering throug the pipe I, and the impure and cold air at the botton of the roomV passing through the 1 e p In case the temperature of either room becomes too hilglh, it may suddenly be lowered by opening t e damper of the pipe K, which will admit a volume of pure cold air, the draft being produced by the heat of ventilating chamber G, and the temperature of each There is' rooms -by the occupants.
room may be regulated by adjusting the dampers of the pipes I and also those of the pipes J, K. These dampers may all be adjusted by the occupants of the several rooms as the chains (o) lead into the several rooms through the pipes as before stated. A
In case at any time there is no fire in either ofthe stoves B, C, the lamp L may be lighted, which will suiiiciently rarefy the air in chamber H to produce suflicient draft for ventilation and the heat ofthe lue F, as well as that of the chamber G, may be re ulated by adjusting the dampers (e) (j), for t e heat of both chambers may, by opening dampers (e), (j), be made to pass up into chamber H into pipe (g).
n the patent granted to John Sawyer the pipes K are not used nor are the dampers (h) employed; there is no means devised for the regulation of the temperature of the several The hot air Hue F extends u ward the whole height of the building, and) there is no communication between tIle smoke pipe, or rather the pi e (g), and the hot air flue F and ventilating ue G, whereby either or both may be used, or the temperature of either regulated as desired without affecting the temperature of the other. Thus it will be seen that my improvement possesses many advantages over the one patented by John Sawyer. It is cheaper to construct; may be arranged with facility; and the temperature of all or either ofthe rooms in a building regulated as desired. l
I do not claim the hot air pi es I, hotsair iiue F, Ventilating lue G, an air-heating chamber A, provided with cold air pipe D, for these, arranged as shown, have been previously used and patented by John Sawyer, nor do I claim either of the parts herein described separately; but,
I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The pipes K for the admission of cold air direct into rooms, when said pipes are made to pass through the Ventilating chamber G for the purpose of creating the necessary draft as described, and arranged and used in connection with the hot air pipes I, and Ventilating pi es J as shown.
2. I also claim t e chamber H placed over the hot-air flue F and ventilating chamber G, when arranged relatively with the flue F, chamber G, and pipes (a), (g), as shown, for the purpose specilied.
CHARLES B. SAWYER.
