Founded in 1845 as the Hamilton Agricultural Works as a partnership between Job E. Owens, Clark Lane and Edbridge C. Dyer. This company was both a manufacturer and a reseller of woodworking machinery, especially sawmills. The three titular heads of this company were Job E. Owens, Clark Lane, and Elbridge C. Dyer. They were in business until about 1880. It is mentioned in the Encyclopedia of American Steam Traction Engines that the General Machinery's book states "In 1882 this firm was reorganized by the original George A. Rentschler and his associates, J.C. Hooven, Henry C. Sohn, George H. Helvey and James E. Campbell, and became the Hooven, Owens, Rentschler Company."
