The Shortt clock, made in the 1920s, is the most famous accurate clock pendulum ever known, having an accuracy of one second per year when kept at nearly constant temperature. Almost all of a pendulum clock's accuracy resides in its pendulum. If the pendulum is accurate, the clock will be accurate. In this book, the author describes many scientific aspects of pendulum design and operation in simple terms with experimental data, and little mathematics. It has been written, looking atall the different parts and aspects of the pendulum in great detail, chapter by chapter, reflecting the degree of attention necessary for making a pendulum run accurately. The topics covered include the dimensional stability of different pendulum materials, good and poor suspension spring designs,the design of mechanical joints and clamps, effect of quartz on accuracy, temperature compensation, air drag of different bob shapes and making a sinusoidal electromagnetic drive. One whole chapter is devoted to simple ways of improving the accuracy of ordinary low-cost pendulum clocks, which have a different construction compared to the more expensive designs of substantially well-made ones. This book will prove invaluable to anyone who wants to know how to make a more accurate pendulum orpendulum clock.

This beautiful book relates the incredible story of how leading clockmakers, primarily of England, struggled to control accurate timekeeping for over 300 years. A remarkably thorough yet concise text, by several of todays leading horologists, is accompanied by nearly 1,000 photographs of clocks, which demonstrate each fascinating development. From museums of international significance, as well as private collections worldwide, the best examples of each new invention to establish accurate time-keepers is illustrated and recorded here. Chapters are devoted to the Royal Observatory at Greenwich and many of the brilliant men of science who made instruments and provided timekeepers. Georgian, Regency, and Victorian advances are shown to have contributed to the eventual success of accurately measuring time, that is so crucial to the success of todays highly integrated society.

This fascinating look at precision time keeping in England is filled with over 700 photographs of historically significant regulators by some of the most well-known 18th and 19th century horologists: Shelton, Ellicott, Arnold, Cumming, Earnshaw, the Vulliamys, Reid, and Hardy. The development of the cases is also explored, from the early Georgian to classic Victorian styles. Concise, thorough text informs and engages the reader in the history of accurately measuring time.
