Brothers Dixon, Monroe and John Patterson, formed the Patterson Machine Company in 1878.  At the time, the Company specialized in equipment designed to service the thriving pottery industry in East Liverpool, Ohio.

Over time, as industrial production in the United States ramped up significantly, Patterson Machine expanded into a multitude of enterprises including steel products and industrial processing equipment.

Patterson Test Laboratory

After World War II, the Patterson Foundry and Machine Company grew by leaps and bounds, adding separate machinery and process engineering divisions. As the Company’s quality, durability and revolutionary equipment designs became widely recognized, customers from all over the world sought out Patterson to create custom designs to meet their specific processing needs.

Over the years, the company was separated into various divisions and subsidiaries.  In 1988, the Gorman-Rupp Company acquired the Patterson Pump Company along with the Patterson Process Equipment Division.

In 2000, the assets of the Patterson Process Equipment Division were sold by the Gorman-Rupp Company, and the Patterson Process Equipment Corporation was formed.
