Excerpt from Mechanism The writer's aim has been to cover the subject of mechanism as briefly, simply and clearly as possible. The text is designed for a half year's work of one lecture, one recitation and four hours' drafting work per week. No especial claim to originality of subject matter can be made, nor has the writer found need for a special effort in this direction. The arrangement and method of treatment are new, and these the author bases upon satisfactory results obtained in the work of his classes in the College of Engineering of the University of Wisconsin. After a brief discussion of motions and velocities linkages are taken up, as they are comparatively easy for the student to understand, and simple problems can be given out while the subject is yet new to him. Cams are taken up in detail, as they form a part of the subject in which the student needs considerable practice in order to work out original problems, and practically all cam problems are original. The involute system of gearing is taken up before the cycloidal system, because it seems to the writer easier for the student to grasp. Having once become familiar with the involute system, the student can more readily understand the cycloidal. Furthermore, the involute system is in more general use at the present time. Problems are given at the end of each chapter. Some of these are designed especially for drafting-room work, and the necessary instructions as to scale, position of drawing on the sheet, method of procedure and time, etc., are given. These few problems are not intended to exhaust the subject, but rather to serve as a guide for instructors in giving the drafting-room work in connection with the recitations. Quotations have been made from the various authorities, and credit given where the quotations appear. The writer wishes to express his thanks to the several authors from whom he has made quotations, the manufacturing companies who have furnished cuts and to all others who have aided in the preparation of the manuscript.
