Excerpt from Principles of Mechanism: A Treatise on the Modification of Motion, by Means of the Elementary Combinations of Mechanism, or of the Parts of Machines, for Use in College Classes, by Mechanical Engineers, Etc, , Etc This work aims to treat the whole subject of Mechanism in such systematic and comprehensive way that by its aid any machine, however elaborate, may be analyzed into its elementary combinations, and the character of their motions determined. In the classification, the System of Prof. Robert Willis has been followed in the main, as serving best the present purpose, and largely his names and terms as well. The work contains the substance of lectures given in my classes during the past twenty-seven years, with such additions and amplifications as might come by reason of a somewhat extended with an aptitude of the thinking out of inversions involving more or less novel and varied forms and combinations. besides Willis, some of the Authors whose works have been referred to with profit may be named: Prof. C. W. MacCord, Geo. B. Grand, J. W . M. Rankine, F. Renleaux, J. B. Belanger, Ch. Laboulaye. Some of the topics to which special attention is invited, as embracing either entirely new solutions of important questions, or previously unpublished discussions and extension of inquiry concerning them, are: Log-spiral Multilobes as derived form one spiral, also Proportional Sectors. Easements to Angular Pitch Lines. Transformed wheels. General Solution of Non-circular Wheels, External and Internal, for the case of Given Laws of Motion. Similar and other Wheels from Auxilliary Sectors, Plane and Bevel. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
