Double Glazed Windows 



The double glazed window is essential in the dairy barn, because the dead air space 

 between the double glass prevents undue radiation of heat, and eliminates condensation 

 of moisture on the windows. 



The window illustrated on page 294 is the James standard barn sash, 9 lights, each 

 8 in. X 14 m., I %-in. glazed double glass. Glass is of single strength. 



The Sash is 29 in. x 14 in. over all. 



James Window Ventilators 



For use where the fresh air enters the barn through the windows. James Window 

 Ventilators when the windows are tilted in, throw the fresh air up against the ceiling, 

 diffusing it and prevent the air entering the stable at the sides of the open windows. 



Furnished with a device that permits locking of the window in any of five positions; 

 this holds the window solid and prevents the wind from knocking it back and forth. 



James Registers 



(For Intakes Only) 



The James registers are designed specifically for barn ventilation purposes. Registers 

 made of cast iron have two serious objections: the metal takes up too much room in the 

 opening, cutting down the effective area; in the second place the cast iron registers are 

 too quickly affected by the moisture usually found in the dairy stable. 



The wire mesh of the James register gives far greater effective opening and the register 

 being galvanized throughout is not affected by moisture. In twenty-four hours, twenty 

 cows will throw off moisture equal to almost one barrel of water; this shows how important 

 it is that the registers be galvanized. 



The complete register has a "tell-tale" device to fasten register open in several posi- 

 tions; a glance down the row of tell-tales shows which registers are open and how much. 



Register faces (designed for outside intakes only) are regularly furnished 8 in. x 

 8 in., I in. X I in., 6 in. x 14 in., 8 in. x 1 4 in., I in. x 1 4 in., I 4 in. x 14 in. 



The complete registers are furnished: 8 in. x 8 in., 1 in. x 10 in., 1 4 in. x 14 in. 



The 1 4 in. X 14 in. complete register is recommended for use where the intake flues 

 open into the stable — that is, in the ceiling or side wall near the ceiling. This size 

 being larger than the intake flues, reduces the high velocity of the incoming air, drafts are 

 lessened and better diffusion of the fresh air secured. 



The 8 in. x 8 in. and 1 in. x 10 in. registers are intended for concrete, brick and 

 hollow tile wall and under conditions where there are but a few head of stock.
