This is a sales brochure from the Samas punched card division of Underwood. Before electronic computers a lot of companies did their data processing on punched card machines.
In 1915 the American company Powers Tabulating Machine Company established European operations through the Accounting and Tabulating Machine Company of Great Britain Limited, in 1929 renamed Powers-Samas Accounting Machine Limited (Samas, full name Societe Anonyme des Machines a Statistiques, had been the Power’s sales agency in France, formed in 1922).
In 1952, Underwood, the typewriter manufacturer, acquired the American punched card tabulating equipment assets of the British Powers-Samas company.
Unlike IBM equipment Powers-Samas equipment was entirely mechanical. Rectangular holes in punched cards were converted into electrical signals as they passed under a row of wire brushes. Pins that could drop through round holes in cards were connected to linkages and their displacement when a hole was present actuated other parts of the mechanism to produce desired results.”
The next two images show the range of equipment that might be found in a punched card installation.
Some of the reports that could be generated by a punched card installation.
