Frames.

Material. - The following pieces enter into a window-frame the size of that mentioned in the previous Exercise:

Two pulley-stiles,

a, Figs. 1, 2, and 3,

1 1/4" thick,

5" wide,

6' 1" long.

One head,

6, Figs. 2 and 4,

1 1/4" "

5" "

2' 5 3/4" "

One sill,

c, Figs. 1, 2, and 4,

1 1/4" "

5 1/2" "

2' 5 3/4" "

One sub-sill,

d, Figs. 1, 2, and 4,

2" "

6 1/4" "

3' 4" "

Two casings,

e, Figs. 1 and 2,

7/8" "

1 3/4" "

5' 6" "

One casing,

f, Figs. 1 and 2,

7/8" "

1 3/4" "

2' 7" "

Two parting-strips,

g, Figs. 1 and 2,

1/2" "

7/8" "

5' 6" "

One parting-strip,

h, Fig. 2,

1/2" "

7/8" "

2' 5 3/4" "

Two hanging-stiles,

i, Fig. 1,

1 1/4" "

4 1/2' "

5' 7" "

One top,

j, Fig. 1,

1 1/4" "

4 1/2" "

3' 2" "

The pulley-stiles are grooved 1 1/2 from the face-edge to receive the parting-strips, and at the top and bottom for the head and sills. The pulleys are let in with the chisel (d, Fig. 3); the pocket formed by two oblique saw-cuts, the bottom beveled with the chisel and secured by two small nails, and the top screwed (e, Fig. 3). The head b, sill c, and a portion of the sub-sill (d, Fig. 4), are of the same length, the sills beveled before nailing in place. The sub-sill should be grooved on the under side, to receive the siding, and prevent draughts under the window (d, Fig. 2).

The top parting-strip is the full length of the groove, the side parting-strips butting against it to hold it in place; usually none of these strips are nailed, the paint serving to secure them. If the hanging-stiles are chamfered, beaded, or molded, the joint with the top must be like that of Fig. 8, Exercise 16.

Door-frames are much simpler in construction. The diagrams, Figs. 5 and 6, give the necessary parts for an outside door 7' high and 2' 10" wide. The jambs, a, are rabbeted and grooved to receive the head. The sill is nailed to the ends of the jambs. Frames for inside doors are made of three pieces, the jambs and head.

Window and door-frames are built at the same time or before the frame is put up, and are placed in position before the siding is nailed on.

The diagrams in this Exercise are drawn to a scale of 1/2" to 1'.
