Not illustrated. 1867 Excerpt: ... 41 PLATE 26. The Plan of a Niche in a circular Wall being given, to find the FronPrib. B is the plan given, which is a semicircle whose diameter is a b, and a, i, k, I, in, h, the front of the circular wall. Suppose the semicircle B, to be turned round its diameter a b, so that the point v may stand perpendicular over h in the front of the wall, the seat of the semicircle standing in this position upon the plan will be an ellipse. Then divide half the arch of B upon the plan into any number of equal parts, as five; draw the perpendiculars 1 d, 2 e, 3 /, 4 g. Upon the centre c with the radius c h, describe the quadrant of a smaller circle, which divide into the same number of equal parts as are round B. Through the points 1, 2, 3, 4, 5, draw parallel lines to a b, to intersect the others at the points d, e, f, g, h. Through these points draw a curve: it will be an ellipse. Then take the stretch-out of the rib B, round 1, 2, 3, 4, 5, and lay the divisions from the centre both ways at F, stretched out; take the same distances d i, e k, fl, g m, from the plan, and at F make d i, e k, f1, equal to them, which will give a mould to bend under and mark the front-rib, so that the edge of the frontrib will be perpendicular to a, i, k, I, m. The curve of the front-rib at A is a semicircle, the same as the ground-plan; and the. back-ribs at C D and E are likewise of the same curvature. The curve of the mould F will not be exactly true, as the distances d i, e k, f I, &c, at B, are rather too short for the same corresponding distances upon the mould at F; but in practice it will be sufficiently near for plaster-work; but those who would wish to see a method more exact, may examine Plate 12, fig. 1, where C is the exact soffit that will bend over its plan at B. In ap...
