CHAPTER LXIX 

 BARN FRAMING 



Roofs. Several types of roofs are used in barn construc- 

 tion. The hip roof, which slopes from the four sides of the 

 barn to a point, is sometimes used for small barns. The 

 shed roof, which slopes only one way, is used for narrow barns. 

 The gable roof slopes in two directions and has gables, from 

 which it derives its name. Gable roofs are quite generally 

 used for barns. The curb, or gambrel, roof is much like the 

 gable roof, except each side of the roof has two pitches. 

 This type of roof is quite generally used for barns, and, in 

 addition to being quite rigid when properly constructed, it 

 adds to the capacity of the haymow. 



The Braced or Full Frame. In this type of frame heavy 

 timbers are used, which are mortised and pinned together. 

 Many barn frames have been made after this style, but the 

 cost of the lumber and the advantages of the plank frame 

 have caused an almost complete discontinuance of this style 

 of frame. When now used it is a modification of the old 

 form. 



The Plank Frame with Purlines. In this type of barn no 

 attempt is made to keep the haymow free from framework, 

 and the long rafters are supported upon the purlines resting 

 upon posts throughout the frame. It is possible to keep the 

 mow free from framework directly under the hay carrier 

 . track, and when so constructed it should not be inconvenient. 

 This type of a frame is not generally popular, but there can be 

 no serious objection to having the posts support the rafters 

 when they are properly placed.
