EXCEPTIONAL QUALITY & ABSOLUTE DEPENDABILITY

A Rich Legacy

The Cooper-Bessemer engine is the embodiment of the rich history of Cooper Machinery Services. In 1833, Charles and Elias Cooper started a foundry in Mt. Vernon, Ohio that produced farm equipment. A few years later, they expanded to horizontal gas compressors. The C. & G. Cooper Company eventually merged with the Bessemer Engine Company of Grove City, Pennsylvania, and formed Cooper-Bessemer Corporation in 1929.
