od how to obtain the pattern for the openingin the cone to miter with the cylinder. For this proceed as follows:Draw radial lines from I in plan through the intersectJ_ons 1, 2, 3,4, and 5, cutting the outer curve E F G H at 1, 2, 3C4, and 5,resj)ectively. Now with A B in elevation as radius and A^ as center,describe a short arc as S T. Place the arc as far above the marginline as the j)lan G, and have S T central between the plan andmargin line. From A^ drop a vertical line intersecting the arc S Tat 1. Now starting from 1, set ofiP on either side of the centerline A^ 1 the distances shown in plan from 1 5 to 4 to 2 to 3,as shown by sindlar numbers on S T. From these points drawradial lines to A. Kow^ using A as center and with radii equalto A e\ A f/, A r, A 1j\ and A a in elevation, describe areaintersecting respectively the radial lines A 1 at e, 2 2 at d d\3 3 at c c\ 4 4 at V l\ and A 5 at a\ Through theseintersections trace a line as shown, which wdll be the desiredopening. 138
