Page 370 - Ah, to build, to build ! That is the noblest art of all the arts. Painting and sculpture are but images, Are merely shadows cast by outward things On stone or canvas, having in themselves No separate existence. Architecture, Existing in itself, and not in seeming A something it is not, surpasses them As substance shadow.
Page 257 - No. 1, 29 more", as 30 sheets are required to go around the tower, and cut 29 more for course No. 1. Treat all of the paper patterns from No. 1 to the apex in similar manner. Of course where the patterns become smaller in size at the top, the waste from other patterns can be used. In Fig. 217 is shown how the sheets should be edged, always being careful to have the narrow side towards the top with the edge toward the outside, the same as in flat seam roofing.
Page 300 - For the development of the hexagonal prism, extend the line 4" 1" as shown by HJ, upon which place the stretchout of twice the number of spaces contained in the half section F, as shown by similar figures on the stretchout line H J. From these points, at right angles to HJ, draw lines as shown, which intersect by lines drawn at right angles to the line of the prism from intersections ly to 4v, thus obtaining the points of intersection 1X to 4X.
Page 160 - Take the various lengths from 2 to 3 to 4 to 5 to 6 to 7 to 8 to A in plan and place them as shown by similar numbers on the horizontal line ab (Fig.
Page 73 - ... of the vertical cylinder, and B its elevation. Draw the plan of the horizontal cylinder C, shown in elevation by D placed in the center of the vertical cylinder. Draw the half section E in plan and divide it into equal parts, as shown from 1 to 3 to 1. In a similar manner draw the half section E1 in elevation, which also divide into the same number of spaces as E, reversing the numbers as shown. The following suggestions are given to avoid confusion in numbering the points or corners of irregular...
Page 264 - J inches and HS equal to 1 £ inches respectively. In similar manner draw LD and OC and connect by lines the points PD and S C. Then will PSCD be the pattern for the standing seam strip, of which 22 more will be required. When the strips are all cut out, use the roofing tongs and bend up the sides, after which they are laid on the tower, fastened with cleats, and double seamed with the hand seamer and mallet in the usual manner. If the tower was done...
Page 260 - Fig" 221' desired, bend up 1J inches and 1J inches, giving a f-inch finished doubled seam in the first case and a 1-inch seam in the second. When laying standing-seam roofing, in no case should any nails be driven into the sheets. This applies to tin, copper or galvanized iron sheets. A cleat should be used, as shown in Fig. 222, which also shows the full size for laying the sheets given in Fig. 221. Thus it will be seen in Fig. 222 that j inch has been added over the measurements in Fig.
Page 75 - ... of the opening to be cut into the quadrangular prism, is obtained by extending the line DE in elevation as NO, upon which place the stretchout of one-half the section A, with the various points of intersection, as shown by similar figures on O N. At right angles to ON erect lines from these points, which intersect by lines drawn from similarly numbered intersections in elevation at right angles to the quadrangular prism, thus obtaining the points of intersection 1'" to 4'
Page 322 - F1, and through the figures, draw lines, which intersect with lines drawn at right angles to EO 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.
Page 309 - B. The problem consists in obtaining the developments of the gable mouldings on a square turret. In developing this pattern, the half-elevation only is required, as shown in Fig. 301, in which first draw the center line EF; then establish the half-width of the turret, as CD, and draw the rake B C. At right angles to the line BC, and in its proper position as shown, draw the profile A, which divide into equal spaces as shown by the figures 1 to 6, through which, parallel to BC, draw lines intersecting...
