WarimiMg Rooms by Bleated Air. 



Fig. 8. 



"In peace prepare for war,' is a maxim as 

 important as it is familiar to our readers. 

 Our present version of it is, in summer pre- 

 pare for winter. Tliis is our reason for offer- 

 ing at thiis time the following article from the 

 Genesee Farmer on warming rooms by lieat- 

 ed air. The subject is one of importance. 



EXPLANATIONS. 



A Ash-pit; B Furnace; C Flue; D 

 Drums; E Smoke-pipe. 



In the figure the ash-pit is supposed to be 

 eight inches in height, with a door in front, 

 in which is an aperture for the admission of 

 air. 



The furnace above it is constructed of cast 

 iron plates. It is three feet in length, eighteen 

 inches in height, and of the same width. A 

 g-rating upholds the wood. 



The flue C is eight inches in diameter, and 

 two inches in height. 



The drums D are three feet in length, 

 eighteen inches in width, and four inches 

 high. They are connected by flues at tlieir 

 alternate ends, similar to C. Their number 

 may be profitably increased, if the height of 

 the room will allow. The two upper ones 

 are of sheet iron. 



The smoke pipe E may be carried where 

 most convenient. On account of the rapid 

 accumulation of soot, however, the shorter the 

 distance, the better. 



For the purpose of cleaning the drums, a 



small door is made in the back end of each. 

 They are supported at the end opposite the 

 furnace by a brick wall, F. 



At the distance of two feet from the fur- 

 nace, a brick wall is constructed around the 

 whole. It is carried up four inches above the 

 upper drum, and is then extended across, sup- 

 ported by bars of iron. Outside of this, and 

 leaving at the sides and top a hollow space 

 of two inches, a wall is built similar to the 

 former. 



It will be observed by reference to the fig- 

 ure, that the inner wall in front is carried 

 over the furnace, and a space is necessarily 

 left in the outer one opposite the door. On 

 one side of the furnace four or five holes, 

 four inches square, are left through both 

 walls near the bottom. The air passing 

 through these becomes strongly heated in its 

 ascent, by the drums, wall, &c,, and is con- 

 ducted by pipes of tin from eight to twelve 

 inches in diameter, set as nearly upright as 

 possible, to the rooms above. Grates of brass 

 or iron on a level with the floor regulate the 

 quantity of air admitted, and consequently 

 the heat of the room. The furnace should be 

 set in a room in the cellar entirely devoted 

 to the purpose, and the window left open ; but 

 if tliis cannot be done, an air trunk one foot 

 square must be constructed, leading from 

 without the building through the outer wall 

 of the furnace; for few things are more in- 

 jurious than the breathing an atmosphere 

 loaded with the products of the fermentation 

 of vegetables which are kept in the cellar.
