Paperback. Condition: New. Print on Demand. This book presents a novel system of Time Telegraphs (electric clocks) created by the author. In an era when electric clocks were marked by serious drawbacks such as noise, fragility, and unreliability, this book introduces a system that addresses these issues head-on. The author's system boasts a unique 'Sparkless Current-Breaker' that eliminates the destructive spark produced by induced currents, ensuring a more stable and longer-lasting operation. Moreover, the author introduces a novel 'Electro-Magnetic Escapement' that eliminates the violent actions and loud clatter of armatures in conventional electric clocks, improving overall clock performance and longevity. Beyond the technical advances, the book underscores the author's keen understanding of the broader challenges and potential of Time Telegraphy. The author emphasizes the role of Time Telegraphs in distributing accurate time across vast distances, with applications in public transportation, industrial settings, and everyday life. This book is a must-read for engineers, electricians, historians of technology, and anyone interested in the evolution of timekeeping and the practical applications of electricity. The author's insights into the complexities of electric clocks and his innovative solutions continue to shape the field of Time Telegraphy today.
