Machine drawing; a practical guide to the standard methods of graphical representation of machines, including complete detail drawings of a duplex pump and of a direct-current generator . e 3V, length of face 1|.Make an outline like Fig. 120, indicating the pitch diameters, pitchcones, and normal cones. This plate should be inked in, fine lines being used for the con-struction lines, and heavy ones for the body of the gears, which maybe made any proportions to suit the students conception of what theyshould be. This may be treated as a case for development of thestudents mechanical judgment and sense of proportion, based, ofcourse, on the exact skeleton outline made from the data as given.
