Description 

The Chapin Mine Pumping Engine is a steeple compound condensing engine capable of lifting 200 tons of water a minute, equivalent to 4 million gallons a day. Edwin Reynolds and his nephew, Irving, designed the steam-driven pumping engine for the Edward P. Allis Company in Milwaukee, Wisconsin, where the engine was constructed. The pump gained world-wide attention as the largest steam-powered pumping engine and its amazing efficiency. The nickname came from the pump being modeled after pumps used in mining operations in Cornwall.

The Edward P. Allis Company, in Milwaukee, was noted for construction of special pumps, mills, steam engines and industrial machinery. It was the largest employer in the area. After Allis' death, the company merged with other manufacturers to form the enormous Allis-Chalmers Corporation.
