Fig. 302 shows the elevation of one of four similar gables occurring in a square pinnacle. The profile of the molding is shown at P. The first step is to obtain the miter line or elevation of the miter shown at K, from which to derive the pattern. Draw the profile P in the molding, as shown, placing it so that its members will correspond with the lines of the molding. Draw a second profile, P1, in the side view of the gable, placing it, as shown in the engraving, so that its members will coincide with the lines of the side view. Space both of these profiles into the same number of parts in the usual manner, and through the points thus obtained draw lines parallel to each of the moldings respectively, as shown, until they intersect, and trace a line through the points of intersection, as shown at K. Then K is the line in elevation upon which the moldings will miter. Draw the center line O M, which represents the miter at the top of the gable.
For the pattern of the molding lay off a stretchout of the profile upon any line, as G H, drawn at right angles to the line of the gable in elevation, as shown by the small figures. Through these points draw measuring lines, as shown. Place the T-square parallel to the stretchout line, or, what is the same, at right angles to the line of the gable, and, bringing it successively against the several points in the miter lines O M and K, cut the corresponding measuring lines, as shown, and trace lines through the intersections. This completes the pattern of the molding, to which the piece forming the roof may be added as follows: Make L D1 equal to E D of the side view of the gable and set it off at right angles to L B1. In like manner, at right angles to the same line, set off A1 B1 equal to A B of the side view, and draw the lines D1 A1 and A1 F, as shown.
