Now divide the normal profile of the bracket into equal spaces, as shown by the figures 6 to 15, through which, parallel to E 0, draw lines intersecting the normal sink profile from 10' to 15' and the face lines of the bracket EFG, JH, KI,, and ONM, as shown. To obtain the true profile for the side of the bracket on the lines OM and GE, pro ceed as follows: Parallel to OM, draw any line, as Y' and at right angles to OM, and from the various intersections on the same, draw lines indefinitely, crossing to the line Y' Z' as shown. Now, measuring in each instance from the line YZ in the normal profile, take the various distances to points 6 to 15 and 15' to 10', and place them on similarly numbered lines measuring in each and every instance from the line Y' Zl, thus obtaining the points 6' to 15' and 15" to 10", as shown. Trace a line through the points thus obtained. Then will Y' 6' 7' 9' 10' 15' be the pattern for the side of the raking bracket, and 10' 10" 15" 15' the pattern for the sink strip shown by the lines K L and H J in the front.
For the pattern for the face strip B, draw any line, as A' B', at right angles to G M, upon which place the stretchout of 10 15 in the normal profile, as shown from 10 to 15 on A' B'. Through these points, at right angles to A' B', draw lines as shown, which intersect with lines drawn from similar intersections on the lines F G and H J. Trace a line through points thus obtained as shown by F° G° H° JO, which will be the pattern for the face B, B.
The pattern for the cap D and the face A will be developed in one piece, by drawing at right angles to E0 the line E' P. At right angles to E' F', and through the figures, draw lines, which intersect with lines drawn at right angles to E0 from similarly numbered intersections on REF and NOP. A line traced through the points thus obtained, as shown by R° E° F° and N° O° P° will be the pattern for D and A.
For the patterns for the cap returns R E and 0 P, draw any line at right angles to 1 1 in the normal profile, as G', upon which place the stretchouts of the profiles R E and 0 P, being careful to carry each space separately onto the line H' as shown respectively by 6° 1° and 6z 1a. Through these points draw lines at right angles to H', which intersect by lines drawn at right angles to 1 1 from similar numbers in W and X. Trace lines through the points thus obtained. Then will W S' be the pattern for the lower return of the cap, R E; while JIM' L' K' will be the pattern for the upper re turn, P 0.
In Fig. 316 is shown a perspective view of a gutter or eave trough at an exterior angle, for which an outside miter would be re quired. It is immaterial what shape the gutter has, the method of obtaining the pattern for the miter is the same. In Fig. 317 let 1 9 10 represent the section of the eave-trough with a bead or wire edge at a b c; divide the wire edge, including the glitter and flange, into an equal number of spaces, as shown by the small divisions d to 1 to 9 to 10. Draw any vertical line, as
A B, upon which place the stretch out of the gutter as shown by simi lar letters and numbers on A B, through which, at right angles to A B, draw lines, which intersect by ones drawn parallel to AB from similar points in the section. Trace line through the points thus obtained. Then will C D E F be the pattern for the outside angle shown in Fig. 316.
If a pattern is required for an interior or inside angle, as is shown in Fig. 318, it is necessary only to extend the lines C D and F E in the pattern in Fig. 317, and draw any vertical line, as J H. Then will J D E H be the pattern for the inside angle shown in Fig. 318.
In Fig. 319 are shown a plan and elevation of a moulding which has more projection on the front than on the side. In other words, A B represents the plan of a brick pier, around which a cornice is to be constructed. The projection of the given profile is equal to C, the profile in elevation being shown by G. The projection of the front in plan is also equal to C, as shown by The projection of the left side of the cornice should be only as much as is shown by D in plan. This requires a change of profile through D, as shown by D'. To ob tain this true profile and the various patterns, proceed as shown in Fig. 320, in which AB CD represents the plan view of the wall, against which, in its proper position, the profile E is placed and divided into equal spaces, as shown by the figures 1 to 12. Through 1 2, par allel to C D, draw G F. Locate at pleasure the projection of the re turn mould, as B H, and draw H G parallel to B C, intersecting F G at G. Draw the miter-line in plan, G C. From the various divisions in the profile E, draw lines parallel to C D, intersecting the miter-line C G as shown. From these intersections, erect vertical lines indefi nitely, as shown. Parallel to these lines Prect the line K J, upon which place a duplicate of the profile E, with the various divisions on same, as shown by E'. Through these divisions draw horizontal lines in tersecting the similarly numbered vertical lines, as shown by the in tersections to 12'. Trace a line through these points. Then will F' be the true section or profile on H B in plan.
For the pattern for the return H G C B in plan, extend the line B A, as B M, upon which place the stretchout of the profile F', being careful to measure each space separately (as they are unequal), as shown by figures 1' to 12' on M B.
At right angles to this line and through the figures, draw lines, which intersect by lines drawn at right angles to H G from similar points on C G. Trace a line through the points thus obtained. T h en will H' G' be the pattern f o r th e return mould.
The pattern for the face mould G C D F is obtained by taking a stretchout of the profile E and placing it on the vertical line P 0, as shown by similar figures, through which, at nght angles to P 0, draw lines intersecting similarly numbered lines previously extended from C G in plan. Trace a line through these intersections. Then will 1 B' 12 be the miter pattern for the face mould.
In Fig. 321 is shown a perspective view of a gore piece A joined to a chamfer. This presents a problem often arising in ornamental sheet-metal work, the development of which is given in Fig. 322. Let
