When models of this new plan were completed and operating successfully, Edward E. Kleinschmidt immediately thought of Teletype Corporation and brought the apparatus to their attention, submitting models and patent applications for their evaluation. After numerous conferences and correspondence, however, his offer for the sale of patent rights and models was rejected. Discouraged, he left the completed models at the Highland Park lab and moved to Florida. During the second world war, son Bernard abandoned his printing establishment and started a tool and die shop, using the machinery and facilities of the Laboratories as well as space occupied by his printing shop. The B. L. Kleinschmidt Company was kept busy building tools, dies, and special devices for the war effort. Through Bernard’s associations he learned that the United States Signal Corps needed a light-weight, transportable teleprinter for tactical field use, and he asked his father if he could show the progressive stop printer to the Signal Corps at their Chicago headquarters. His father, in Miami at that time, gave his approval. Two days later, the telephone rang in Miami and it was Bernard saying, “Dad, they are interested and want you to bring the printer model to Army Headquarters in Washington.” Nothing could have pleased his father more! In February of 1944, Edward E. Kleinschmidt demonstrated a working model of his teleprinter in Washington at the office of the Chief Signal Officer. Officials of the Signal Corps were greatly interested in the unit, not only because of its extreme lightness and small bulk, but because of the representations that the basic design features of this tape printer, exclusive of the printing mechanism, could be incorporated in a page-type printer which could be constructed with a total weight of approximately thirty pounds. The machine was subsequently informally tested at the Signal Corps Engineering Laboratories and found to have excellent margins when working without an intermediate relay on very low line current, a highly desirable feature in a piece of tactical teletypewriter equipment. The exhibit at Headquarters was successful, and after operative tests at the Signal Corps’ Coles Signal Laboratories in Red Bank, New Jersey, where approval for further studies was given, the Kleinschmidt organization was asked to prepare plans toward a tactical light-weight printer for field use. It should be pointed out that teletypewriters at that time were heavy, cumbersome, and intended for use only at telegraph offices or at other plant or office fixed installations.
