Object Details
- Egli, Hans W.
- Description
- This is the mechanism for a direct multiplication, lever-set, manual non-printing Millionaire calculating machine. It includes a metal base, an iron frame for the base, and part of the carriage and the mechanism for entering numbers (but only part). Also present are a component used in direct multiplication, and two cranks on their shafts. The parts of the machine are marked with different numbers. The machine has no case or lid.
- Stamped on the iron frame near the right front corner is the serial number: 4154. A mark painted on the carriage reads: 27-80. The number “27-80” indicates that the machine came from the collection of New York teacher and historian of mathematics L. Leland Locke (see accession 155183 and non-accession 1983.3003). Other parts of the machine may well be in non-accession 1983.3003.
- According to the estimates of Daniel Lewin, a Millionaire calculating machine with serial number 4200 was made in 1915. Hence the rough date of 1914 is assigned to this object.
