"In both size and shape, this machine closely resembles the Scribola, illustrated in figure 286 (32 X 9 X 7 cm, 2.5 kg), but instead of a chain drive it has ten adding keys. It prints both individual items and totals on 58-mm wide paper. There is a lever, attached on the right, that is used to add and print the items that have been entered. The totals are printed when the left lever is moved-it is not necessary to enter them again. It has a single-color ribbon.

Capacity: eleven-place setup mechanism, twelve-place result mechanism.

The price of the machine is 400 marks. Manufacturer: Amigo Addiermaschinen Gesellschaft, 11 Müillerstrasse, Stuttgart-Gaisburg."

Melitta (1925)

Martin (US), page 355 - 356

Martin (Dtsch), page 380

 

"This is a miniature pinwheel machine with continuous tens-carry in the revolution counter. The shift from addition to subtraction occurs automatically when the crank is turned in the opposite direction. Manufacturer: Mercedes Bureaumaschinenwerke, Charlottenburg 2, Berliner Strasse 153."

Melitta machines were manufactured by the Mercedes Büromaschinen-Werke, Zella-Mehlis, from 1924 on.

In 1926/27 production was turned over to the Walther Werke, also Zella-Mehlis. Identical machines were sold as Melitta and Walther by both companies.

Melitta machines were also marketed by other companies under their brand, like Stolzenberg.

After World-War II, Melitta models were manufactured and sold independent from Walther (see below).

Produx (1928)

 

Manufacturer: Meuter & Sohn, Berlin, later Hamburg (D)

Otto Meuter started 1918 with the invention of an add/subtract slider, which was marketed under the names "Addiator", "Pro Calculo"  and "Correntator". In 1928 he founded his own company and sold the add/subtract slider under the name "Produx".

From 1953 a 3 species machine (division was not possible resp. very cumbersome) was manufactured and marketed under the name "Multator" (in France "Multical"), one model had the name "a x b x c".
