Chain Belt Company was a company that manufactured chain belts that replace the leather belting used to drive agricultural equipment at the time.
The company was established in Milwaukee, Wisconsin by inventor Christopher W. LeValley, who also went by C.W. Levalley, and two foundry operators, that provided him with $11,000.00 in starting capital, F.W. Sivyer and W.A. Draves. It was incorporated on February 20, 1892. The company applied the concept of chain belts on farm machinery to construction machinery and conveying equipment. Its building was formerly owned by Alonzo Pawling and Henry Harnishfeger of Pawling & Harnischfeger, which eventually became Harnischfeger Corporation.
In the 1890s the company manufactured chain-driven material handling conveyors and bucket elevators for Milwaukee breweries such as the Joseph Schlitz Brewing Company. By 1894 the company began to develop international markets, exporting chains to Europe and opening a sales office in England.
By 1913 annual sales reached $1 million. At that time the company's products were organized into three major divisions: chain products for power transmission; chain-driven construction machinery; and chain-powered bulk conveying equipment.
In 1914 it introduced the Rex brand-name, which was first used on a chain-driven concrete mixer. It soon became a widely recognized trademark.
In 1941 it won the combined Army and Navy Award for Excellence in War Production.
By 1943 it was manufacturing: Rex Chain, Rex Concrete Mixers, Rex Sprockets, Rex Traveling Water Screens, Rex Elevators, and Rex Conveyors and was working on conveyor for chemicals.
By 1944 it was producing rifles, howitzers, anti-aircraft guns(rifles), tank turrets, ammunition hoists for navy vessels and turrets, tracks and gunshields for an armored vehicle called an Alligator.
By 1959 its business was involved in four distinct categories: Construction Machinery, Heavy Bulk Material Handling Systems, Mechanical Power Transmission, Sanitation and Industrial Waste Treatment Equipment.
