A PRACTICAL COURSE IN HOROLOGY 1944

The purpose of this book is to present the fundamentals of horology, both in theory and practice.

Part 1 deals with wheel work and gearing, which involve the work of calculating the number of teeth of missing wheels and pinions and in determining their proper diameters. Principles of escapement design and an analysis of the balance and spring are given considerable space.

Part 2 treats repair methods, in which the making of a balance staff and the adjustment of the escapement are given more than the usual space allotted to these subjects.

Part 3 is concerned with the adjustments to position, isochronism, and temperature, factors that may be called the finishing touches of the horological profession.
