Project Gutenberg 2007-06-30 Public domain in the USA. 455 Playtner, H. R. 31008430 An Analysis of the Lever Escapement Produced by Sigal Alon, Fox in the Stars, Laura Wisewell and the Online Distributed Proofreading Team at http://www.pgdp.net "An Analysis of the Lever Escapement" by H. R. Playtner is a scientific publication written in the early 20th century. The book serves as a comprehensive examination of the lever escapement mechanism, which is crucial for the accurate functioning of watches. Playtner delivers this analysis as a lecture for the Canadian Watchmakers' and Retail Jewelers' Association, offering insights aimed at horologists and enthusiasts of timekeeping instruments. In this detailed work, Playtner explores the mechanics, geometry, and principles behind the lever escapement, tracing its origins to Thomas Mudge's innovation in the 18th century. The book discusses key concepts such as the number of teeth in the escape wheel, the importance of precise angles, and the relationships between various components, such as pallets and teeth. Through diagrams and calculations, the author delves into practical applications, theoretical underpinnings, and the craftsmanship necessary for producing efficient escapements. Ultimately, Playtner emphasizes the importance of both theory and practice in horology, providing a resource that seeks to enhance the reader's understanding and skills in watchmaking.
