Madas (1908)

Martin (US), pages 196 - 198

Martin (Dtsch), pages 208 - 210 & 427 - 430

 

"The word Madas is composed of the initial letters of the words Multiplication, Automatic Division, Addition, and Subtraction. The machine belongs to the class of stepped drum machines but has automatic division. In all other calculating machines, division requires great attention on the part of the operator because a relatively large number of different kinds of manipulations. and even corrections, are necessary for every individual place of the quotient. The Madas divides entirely automatically. All that is necessary is to enter the dividend and the divisor and then to turn the crank until the bell sounds, which indicates that the division has come to an end. The computation of the quotient, the shifting of the carriage, and the indication of the remainder are automatically taken care of by the machine.

Designer: Erwin Jahnz, Manufacturer: H.W. Egli, A.G. in Zurich."

Note: H.W.Egli also produced the Millionaire calculation machine
