Bunzel-Delton (1908)

Martin (US), pages 198 - 199

Martin (Dtsch), pages 210 - 211

 

"This is a stepped drum machine. The designer was Hugo Bunzel, a calligraphy teacher and former painter in Prague. The manufacturer was the Bunzel-Delton-Werk Fabrik automatischer Schreib- und Rechenmaschinen, Favoritenstrasse 194, Wien X.

The machine was supplied with one and two result mechanisms, with and without tens-carry in the revolution counter, and with additional stepped drums. In some machines one could switch from addition-multiplication to subtraction-division by reversing the direction of the crank. A number of different sizes were available. Factories were set up in Austria, Germany, Italy, and France, although the number of units sold was never large. At the end of 1915. production was stopped because of the death of the factory owner.

Since that time, a Bunzel-Delton calculating machine factory has been set up again (12 Klimschg., Vienna III/I), although there are no details available about their machine at this time."

Note: the translation incorrectly states "factories were set up in Austria .....", it should read: the product was introduced in Austria, Germany, Italy and France, although .........
