Before obtaining the pattern it will be necessary to obtain a true section or profile at right angles to the moulding F D. To do so, pro ceed as follows: Transfer the given profile L M in elevation in Fig. 307, with the divisions and figures on same, to a position at right angles to F D of Fig. 308, as shown at L. At right angles to F D, and from the intersections in the profile L, draw lines intersecting those of simi lar numbers in F D E J. Trace a line through intersections thus ob tained, as shown from 1 to 8, thus giving the profile M, or true sections at right angles to F D.
For the pattern, proceed as follows: At right angles to F D, draw the line H K, upon which place the stretchout of the profile M, as shown by the figures. At right angles to H K, and through the figures, draw lines, which intersect with those of similar numbers drawn at right angles to F D from points of intersection in the miter-lines D E and J F, as shown. Lines traced through points thus obtained, as shown by N 0 P It, will be the pattern for the raking moulding shown in plan, Fig. 307, by A B C Q'.
In Fig. 300 is shown a view of a spire, square in plan, intersecting four gables. In practice, each side A is developed separately in a manner shown in Fig. 310, in which first draw the center line through the center of the gable, as E F. Establish points B and C, from which draw lines to the apex F. At pleasure, establish A D, At right angles to F E, and from B and J, draw the lines B H and J K respectively. For the pattern, take the distances B K, K A, and A F, and place them as shown by similar letters on the vertical line B F in Fig. 311. At right angles to B F, and through points B and A, draw lines as shown, making B H and B H' on the one hand, and AN and AO on the other hand, equal respectively to B H and A N in elevation in Fig. 310. Then, in Fig.
311, draw lines from N to H to K to H' to 0, as shown, which repre sents the pattern for one side.
In Fig. 312 is shown a perspective view of a drop B mitering against the face of the bracket C as indicated at A. The principles for developing this problem are explained in Fig. 313, and can be ap plied to similar work no matter what the profiles of the drop or bracket may be. Let A B C D E represent the face or front view of the bracket drop, and F H G I the side of the drop and bracket. Divide one-half of the face, as D C, into equal spaces, as shown by the figures 1 to 7 on either side, from which points draw horizontal lines crossing H G in side view and intersecting the face H I of the bracket at points 1' to 7'. In line with H G, draw the line J K, upon which place the stretch
out of the profile B C D, as shown by 1 to 7 to 7 to 1 on J K. At right angles to .1 K, draw the usual measuring lines as shown. which inter sect by lines drawn parallel to J K from similarly numbered intersec tions on H I. Trace a line through the points thus obtained. Then will J K L be the pattern for the return of the drop on the face of the bracket.
In Fig. 314, A shows a raking bracket placed in a gable moulding. When brackets are placed in a vertical position in any raking moulding, they are called "raking" brackets. B represents a raking bracket placed at the center of the gable. The patterns which will be develop ed for the bracket A are also used for B, the cuts being similar, the only difference being that one-half the width of t h e bracket in B is formed right and the other half left, the two halves being then joined at the angle as shown.
In Fig. 315 are shown the principles employed for obtain ing the patterns for the side, face, sink strips, cap, and returns for a raking bracket. These principles can be applied to anyform or angle in the bracket r gable moulding respectively. Let S U V T represent part of a front elevation of a raking cornice placed at its proper angles with any perpendicular line. In its proper position, draw the outline of the face of the bracket as shown by E G M 0. Also, in its proper position as shown, draw the normal profile of the side of the bracket, indicated by 6-Y-Z-15; the normal profile of the cap-mould, as W and X; and the normal profile of the sink strip, as indicated by 10 10' 15' 15.
Complete the front elevation of the bracket by drawing lines par allel to E 0 from points 7 and 9 in the normal profile; and establish at pleasure the width of the sink strip in the face of the bracket, as at J K and L H. To complete the front elevation of the cap-mould of the bracket, proceed as follows: Extend the lines G E and M 0 of the front of the brackets, as shown by E 6 and 0 6, on which, in a vertical position as shown, place duplicates (W', of the normal profiles W and X, divided into equal spaces as shown by the figures 1 to 6 in and From these intersections in W' and drop vertical lines, ,hich intersect by lines drawn parallel to E 0 from similarly numbered intersections in X, and trace lines through the points thus obtained. Then will It E and 0 P represent respectively the true elevations, also the true profiles, for the returns at top and foot of the cap of the raking bracket.
