Brunsviga S Arithmotype
Four-species pinwheel machine with printing unit (from 1908)
The Brunsviga S Arithmotyp was the first printing four-species calculating machine to appear on the market. The machine is based on a patent issued to Franz Trinks on October 25, 1908 (DRP 226261), which patented the connection between the transmission element (pin wheel) and the printing mechanism. The Brunsviga S arithmotype was marketed by the Brunsviga company as a great development success, because it had been recognized since before 1900 that a synthesis of the printing adding machine (for example, the Burroughs machine) and the four-species machine would lead to an universal calculating machine. The machine remained unrivaled for a while: only two years later, in 1910, the firm of Seidel & Naumann, Dresden, brought a competitor (albeit much heavier and more space-consuming) onto the market in the form of the printing stepped drum machine XxX. However, both machines can only be regarded as stage successes on the way to the printing four-species calculator ("Printing Calculator"), since the calculator and the printing unit formed two separate functional units. Therefore, printing is more than cumbersome, so that it seems explainable that only a few copies of the certainly expensive machine could be sold.
