The plans for a light-weight page printer were submitted to the Signal Corps as requested and were well received by their engineers. These engineers then wrote up specifications detailing their requirements for a rugged, light-weight portable set for hand-carrying through jungles and swamps, and operable under severe climatic conditions; the specifications were submitted to the Teletype Corporation, the Western Union Telegraph Company, and to the Kleinschmidt organization. Western Union did not take on the development job, but Teletype and Kleinschmidt accepted. A contract for the development of a teletypewriter according to Signal Corps specifications was closed with both companies in 1945. The Kleinschmidt Laboratories were not in active operation at this time, so the first development contract was closed with the B. L. Kleinschmidt Company which was fully equipped to carry on the work. Expert tool and model makers were in his employ, some of whom turned out to do well at the drawing board and were of great help in working out mechanical functions. As a matter of fact, five or six of Bernard’s employees are still with the Kleinschmidt Division of SCM Corporation at this writing, some having attained supervisory positions. Edward F. joined his father in further engineering and development work, and models of a typebar page printer and a typewheel page printer to operate at 60 words per minute were built. Upon evaluation by the Signal Corps and Army engineers, a printer with a higher operating speed, up to 100 words per minute, was demanded. This new requirement meant a complete redesign of apparatus, but it was successfully carried through and experimental models were submitted by both companies. Thereupon both Kleinschmidt and Teletype were asked to build ten printers for field tests. This was done, and after extensive field testing, the Kleinschmidt-designed, keyboard-operated, 100-words-per-minute typebar page printer was accepted, and, by order of the then Secretary of War, it was made the standard for the Military, effective on January 1, 1949. (This printer was later to be known as the TT-4 tactical page printer, the principal component of Teletypewriter Set AN/PGC-1.) (See fig. 13.) An announcement from the Department of the Army, in a document released for publication on February 13, 1949,[16] read as follows: _Portable Teletypewriter Developed by Signal Corps_ Portable teletypewriter equipment so light that a parachutist can carry it on a jump from an airplane has been developed and adopted by the Army, promising a major advancement in military communications, the Signal Corps announced today.
