BARN VENTILATION 185 



window open for summer ventilation. G Same, 

 showing shield in place for winter ventilation. 



Note i. This shield is made of sheet or galvanized 

 iron, bent, as shown in sections E and F above, and 

 screwed to the window frame. When in place it de- 

 flects the air upward towards the ceiling, preventing 

 drafts. The opening between this shield and the win- 

 dow frame for the admission of air should be about 

 two inches in width. When the shield is raised 

 slightly, it allows the window to drop forward on its 

 hinges at the bottom and to open fully. 



Note ii. If round iron pipes are used for venti- 

 lating instead of flues, they should be not less than 

 fourteen inches in diameter. Their tops may be cov- 

 ered with revolving hoods, specially constructed to 

 create drafts. If less than four ventilating shafts are 

 used, they should be large enough to have the same 

 capacity. 



The bottoms of all ventilating shafts should open 

 not more than one foot above the floor, and these 

 openings should always be kept free from hay, straw 

 or anything else that will prevent a free circulation 

 of air.
