The Société Alsacienne de Constructions Mécaniques (the Alsatian Corporation of Mechanical Engineering), or SACM, is an engineering company with its headquarters in Mulhouse, Alsace, which produced railway locomotives, textile and printing machinery, diesel engines, boilers, lifting equipment, firearms and mining equipment. SACM also produced the first atomic reactor at Marcoule.
History
Foundation
The company was founded by André Koechlin in 1826 to produce textile machinery. In 1839, he opened a factory to build railway locomotives at Mulhouse in Alsace.[1] The business grew rapidly but in 1871, the annexation of Alsace-Lorraine by Germany, brought about the transfer of some production to Belfort in France. In 1872 the company merged with the Graffenstaden company of Illkirch-Graffenstaden (a suburb of Strasbourg) to form SACM.
Alsthom
The new company diversified into the production of boilers, steel equipment, printing equipment, compressors, firearms and other engineering products growing to 4500 employees by 1910.[2] A new foundry was built in 1922 for textile machinery. In 1928 the Compagnie Française Thomson-Houston merged with the Electrical Engineering division of SACM to form a new company named Alsthom, (Alsace-Thomson), later changed to
Steam locomotives
Production of steam locomotives was originally carried out at Mulhouse and Graffenstaden (for German production), and Belfort for the French production. Both plants also exported models. However, after the First World War, Mulhouse and Graffenstaden built French steam locomotives, and Belfort specialized in the construction of electric locomotives.
During the 1890s the company was particularly noted for its fast and efficient compound locomotives designed by Alfred de Glehn.
Diesel engines
Diesel engines built at Mulhouse have been sold worldwide primarily for ship propulsion, locomotives and railcars, and as power generators. The range of diesel engines produced by SACM included:
MAREP Moteur MGO was the Société de Matériel et de Recherche Pétrolière. Grosshans Ollier refers to Georges Frédéric Grosshans and Jacques Gaspard Ollier who held a patent for liquid-cooled pistons, US patent 3,323,503 of 6 June 1967.[3] Examples of SNCF locomotives using these engines were BB 63400 (MGO engine) and CC 72000 (AGO engine).
- MGO (MAREP Grosshans Ollier) 175 mm bore, 6 to 16 cylinders
- AGO (Alsacienne Grosshans Ollier) 195 mm bore, 12 to 16 cylinders
- AGO (Alsacienne Grosshans Ollier) 240 mm bore, 12 to 20 cylinders
