ICE HOUSES AND 



A removable ventilator is placed in each gable end of 

 the building to permit the free circulation of air in the attic 

 and thus prevent the penetration of heat from the roof. 



The doors may be made as suggested in the drawing 

 or purchased from some company which makes a business 

 of manufacturing refrigerator doors. In either case it should 

 be remembered that a good door is of primary importance 

 in this type of an ice house and care should be taken to 

 secure one which will open easily from either side, and when 

 closed make an absolutely air-tight joint. 



To reduce the refrigeration loss caused by the door 

 being opened while entering or leaving the cold store room, 

 a vestibule is provided which makes it possible to keep one 

 or the other of the doors closed at all times and thus prevent 

 any direct flow of air between the inside and outside. 



If it is found desirable to put a window in the vestibule 

 at least four-inch sash should be used as shown in the draw- 

 ing and fastened rigidly in place. 



A cooling tank of concrete located as shown by the 

 dotted lines in the plan, through which the water from the 

 melting ice passes before leaving the building, would be of 

 considerable value where quantities of milk or cream are 

 being cooled. Such a tank should be about 2 feet 6 inches 

 deep by 4 feet wide and six feet long. It should be pro- 

 vided with an overflow pipe fitted with an "L" and nipple 

 projecting below the high-water level of the tank. The 

 trapped drain in this case would not be needed. 



A Homemade Ice Box Easily Constructed 



Where one does not wish to go to any great expense for 

 a refrigerator, a cheap and very satisfactory ice box can be 

 constructed as shown in the accompanying plans. (Fig. 5.; 



The frame of the ice box is made of 2 x 43 on both 

 sides of which two layers of matched lumber are nailed. 

 Waterproof paper is placed between the matched lumber. 

 The space between the inner and outer wall is filled with dry 

 mill shavings.
