The constructionis the same, except that a circular flaring lip is attached 204 SHEET METAL WORKERS MANUAL to the top. The handle is double hemmed, and the bodyis graduated into four parts and marked on the metal bymeans of the beading machine. (Figure 59.) The dimensions of the measure and method of obtain-ing the pattern for the lip are shown in Figure 174. Firstdraw the elevation A to the required size. Then drawthe side view of the lip B as shown by abed, extending thelines until they intersect at e. With / as center describethe half section of the top of the measure as shown byb5d; divide this semicircle into equal parts as shown. The. Figure 173.—One-Quart Measure with Flaring Lip. lip is an intersected frustum of a right cone, which canbe developed by the radial method. If the time is limited and only a few pieces are re-quired, there are several short methods which can be ap-plied to the same purpose. An approximate pattern de-veloped by one of the short methods in common use isshown in C, Figure 174, and may be produced as follows:Draw a center line as AB and on it fix a convenient pointe. With the compasses set to a radius equal to ed in theelevation A, scribe the arc dbd; starting from the point bspace off a distance dd on each side equal to one-half thecircumference of the top of the measure, as shown by thefigures 1 to 9 in the half-section in the elevation.
