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 . o w HO CO OH w a O X 5f W s &q CO S1 t3 § GO § W £ MACHINE DRAWING PART II MECHANISM DRAWING Study of Mechanisms. In Machine Drawing, Part I, workingshop drawings have been analyzed in detail, systematic processesfor making them have been outlined, and numerous illustrationsgiven and thoroughly discussed. The student as yet, however, hasnot been shown how to originate the theoretical outlines of thesurfaces controlling motion in machines; and it is the purpose ofPart II to accomplish this. I The theoretical shape of the working surfaces of a machine canbe studied and developed to best advantage without any considera-tion as to their strength or their ability to perform work or with-stand service. Such study is a study of the mechanism of a machine,and must always precede the study of design to provide the properstrength. A mechanism, therefore, is a combination of parts so formedand connected as to produce a desired motion, but not necessarilyto perform any specific work. A mac
