of Powers-Samas House, Holborn Bars, London, EC1. Telephone: Holborn 8711, and Croydon (factory from 1932), makers of punched card machines.

Powers-Samas was a British company which sold punched card equipment. The company was in competition with the British Tabulating Machine Co (BTM).

1911 The Powers Accounting Machine Company was formed by James Powers in New York. Powers had worked for the American Bureau of Census maintaining Hollerith’s tabulating machinery. He made several improvements to Hollerith’s original design, including incorporation of an automatic printing mechanism (or tabulator), and a mechanical hole-sensing mechanism.

A lawsuit was brought against Powers on ground of infringement of copyright by a German company acting for the Computing-Tabulating-Recording Company (later to become IBM). Although the German company won, they were obliged to grant Powers-Germany a licence to use Hollerith’s patents on a royalty basis. Powers continued to develop the machines, adding slide punching machines, removable and easily programmable tabulator boxes, etc. which led to increased competition within the industry.

1915 The Accounting and Tabulating Company of Great Britain ("Acc and Tab") was incorporated as a private company in England (formed by the Prudential Building Society). Acc and Tab established a relationship with Powers which eventually became Powers (UK).

1922 Societe Anonyme des Machines A. Statistiques (S.A.M.A.S.) was incorporated in France, handled distribution of Powers machines in France and the French Colonies[1].

The parent Powers company was taken over in the formation of Remington Rand, becoming known as the "Tabulating Machine Division" of Remington; the company later became Unisys.

Post-war the interest in S.A.M.A.S. was reduced to 45%. Vickers-Armstrongs was contracted to produce product for the company to cope with the increased demand[4].

1945 Vickers took an interest in the company[5].

1949 Powers-Samas, one of only 2 British companies involved in punched card machines, terminated its licensing agreements with Remington Rand.[9]

Vickers (Crayford) constructed accounting machines for Powers-Samas

1955 Took a factory at Southport on long lease from Brockhouse Engineering (Southport) to give more capacity for punched card accounting machines[10]
