Fig. 27 shows the method of obtaining the pattern whenthe four sides of the pan have the same bevel. First draw the sideelevation having a bevel indicated at ^21. Now draw ABCD, arectangle representing the bottom of the pan. Take the distanceof the slant 1 - 2 in elevation and add it to each side of the rect-angular bottom as shown by 1, 1, 1 and 1.

. Cyclopedia of architecture, carpentry, and building : a general reference work .... tly under the wired edge of the pan. Apan folded in this way gives a water tight joint without any sol-dering. Fig. 27 shows the method of obtaining the pattern whenthe four sides of the pan have the same bevel. First draw the sideelevation having a bevel indicated at ^21. Now draw ABCD, arectangle representing the bottom of the pan. Take the distanceof the slant 1 - 2 in elevation and add it to each side of the rect-angular bottom as shown by 1, 1, 1 and 1. Through thesepoints draw lines parallel to the sides of the bottom as extend the lines of the bottom AB, BC, CD and DA inter-secting the lines just drawn. Take the projection of the bevel 31 24 TINSMITHING rt to 1 in side elevation and place it on each corner of tlie pan, as,for example, from a to 1. Draw a line from 1 to B. By pro-ceeding in this manner for all the corners, we will have the buttmiters, if the corners were to be soldered raw edge. Where thebevels are equal on all four sides, the angle l^Bl is bisected as. Fig. 28. follows: AVith B as center and any radius draw the arc ff inter-secting the sides of the bottom as shown. Then with a radiusgreater than one half of ff^ with /and^/ respectively as centers,draw arcs which intersect each other at i. Draw a line throughthe intersection i and corner B, extending it outward toward /. Now with 1 as center, and radius less than one-half of I-l,draw arc d-c^ intersecting the line 1 B at J, and intersecting theline Va at c. Then with Z» as center and he as radius, intersect thearc ccl at e. Draw a line from 1 to c, intersecting the line i] at n draw a line to 1^. Transfer this cut to each of the corners,which will complete the pattern desired. Dotted lines indicate thewire allowance. Soinetimes a drip pan is required whose ends have a different 62 TINSMITHIXG 25 flare from those of the sides, and in one case the folded corners areto be bent toward the end, w
