Paperback. Condition: New. Print on Demand. This book explores the technical advancements of type-printing telegraphs throughout the 1800s. Starting with the initial invention of Alfred Vail and the Dial telegraph of Stone in the 1840s, through to the improved systems of Hughes, Farmer, and Phelps, the author provides a detailed account of the evolution of this technology. These type-printing instruments represented a significant departure from the existing Morse system with their step-by-step or synchronous mechanical movements. The author examines each system's key characteristics, such as inking mechanisms and printing methods. Of particular note is the Phelps-Hughes printing telegraph, which operated synchronously at two or more stations, enabling the printing of each letter by a single electric pulse. This advancement greatly enhanced transmission speed. The book highlights the influence of these type-printing telegraphs on the rapid expansion of communication networks and their importance in shaping the development of the broader telegraph industry.
