Advances in Printing Telegraph Technique

    Abstract

    IT is shown in a paper by A. E. Thompson, published in Electrical Communication of April, that at no period in the history of the telegraph has there been such revolutionary improvements in methods and equipment or such rapid development and expansion in its service to the community as during the last ten years. The progress was initiated by the introduction of teleprinter systems, which by providing instruments requiring no telegraphic skill on the part of the operators have completely changed the outlook of telegraphy and greatly stimulated development in all its branches. Teleprinters are superseding all the older types of machine telegraphic apparatus. Even hand Morse working, which has been the backbone of telegraphy for more than a century, has now been abandoned in the British telegraph service, the bulk of the traffic being handled by Creed teleprinters. Similar developments are taking place in other countries. A description is given of the new Creed No. 10 tape teleprinter. The improvements achieved are trustworthy service at 85 words per minute, reduced costs, quiet operation and reduced size. Maintenance costs have been reduced by evolving mechanisms with a breakdown speed exceeding 100 words per minute. The printer operates continuously for 300 hours without requiring lubrication. Ballbearings and oil-impregnated bearings as well as sliding surfaces lubricated by means of oil reservoirs are used. This machine can be used by telegraph administrations and private companies as well as by high-speed news and ticker services.
