Synopsis
Excerpt from Electricity and the Electric Telegraph, Vol. 2
The printing mechanism being at that moment released by the: action of the electro-magnet, an impression of the letter would be taken as it was passing, and SO of any other letter when its corresponding key was depressed.
During the greater portion of the years 1855 - 56 Mr. Hughes, in conjunction with Mr. George 'm. Phelps, an accomplished mechanician, at that time residing in Troy, N. Y., was engaged in perfecting the instrument, with a View to its practical intro duction upon the lines of the American Telegraph Company, which were at that time equipped principally with the House apparatus. During this time two important and in fact essential improvements were made in the invention. The first of these is a device for readjusting the synchronism of the type wheel at the printing of each letter, by means of which any Slight irregularity in the correspondence of the sending and receiving instruments, arising from the mechanical inaccuracies of the governors, or from their imperfect adjustment, is corrected. The second improvement consists in gearing the type wheel Shaft and printing mechanism together, SO as to be driven and controlled by the same prime motor and governor, but in SO arranging the parts that four or five letters in succession upon the type wheel will pass the platen during the shortest interval that can elapse between two successive impressions, by which means, as will be hereafter explained, the effective Speed of transmission is very greatly increased. This important im provement is entirely due to the ingenuity of Mr. Phelps.

Seller rating 5 out of 5 stars
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. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
