Book excerpt: Excerpt from A Practical Treatise on Mill-Gearing, Wheels, Shafts, Riggers, Etc: For the Use of Engineers Tm: circumstances Which have led to the preparation of the following work may be briefly explained. The author was extensively engaged for many years in the practical construction of Mill-gearing; he found the existing rules for calculating the Power of Wheels and Shafts very unsatisfactory; and as to Riggers, the only known rules are of comparatively modern date, and are given in such a form as to be almost useless for practical purposes. Under these circumstances, be was led to search for Rules and to construct Tables for his own daily use, and he now gives the results to the world. It is, perhaps, necessary to say thus much, because the rules are for the most part novel, and it may be well to explain that they have not been adopted in pursuance of any favourite theory, but are the result of the inflexible teachings of a long and varied experience. For the same reason, many examples are given of Wheels, Shafts, Riggers, in practice, that the reader may see how far the rules agree therewith; in fact about one-third of the Tables in the work are devoted to that special purpose. As many of the rules were empirical, and did not admit of a theoretical demonstration, the only course open for proving their correct ness, was by giving examples of successful application.
