Not illustrated. 1912 edition. Excerpt: ...which miters on to it at right-angles, as shown by the plans Fig. 92 _ _ __ and 103. The vertical height of both these members beingr fixed, it remains only to obtain the true outline of either profile, one taken from the of uer as the case may be, it one outline has been drawn, this being the case in this instance as the Fig 109 shows. For number 5 in this case the manner in which the entire operation is accom-plished is as follows, both to obtain the correct corresponding profiles and also the data for the miter line for both members, as demanded for Fig 109 this case. 1 may add at this instance that tl.e seen-a Z.4'-t0th'.f.)()'i.. same principles governing this case are also applicable to most any problem wl ere it is de sirable to join moldings of dlflerent widths to gether and their development in full. First draw the line A to B, Fig. 109. The distance from point A to C in this case being made only the precise length demanded for the miter or width of section number 6; I leave it to the student to add whatever length is desired on any cornice he may employ this method for, my aim being merely to show how to develop the data for a miter-joint of this class, the line from O to point 2 being at right-angles to line A to B--as shown for the top of this section. The outline of the profile is shown from point 2 to 41; this completes the projection of section number 5. Next draw the miter line S to A as shown. Draw line A to K at right-angles to line A to B. Draw the line S to N as shown, the distance from point A to N is the same as the extreme width of section 5 shows as a matter_of course. Now the lines from both the lines S to N and S to O downward have the same corresponding length to each other as shown, but their positions...
