Knight Foundry

Knight Foundry, also known as Knight's Foundry and Shops, is a cast iron foundry and machine shop in Sutter Creek, California. It was established in 1873 to supply heavy equipment and repair facilities to the gold mines and timber industry of the Mother Lode. Samuel N. Knight developed a high speed, cast iron impulse water turbine which was a forerunner of the Pelton wheel design. Knight Wheels were used in some of the first hydroelectric plants in California, Utah, and Oregon. This site is the last water-powered foundry and machine shop in the United States. A 42in Knight Wheel drives the main line shaft, with smaller water motors powering other machines.HistorySamuel Knight came west to California from Maine in 1863. His Knight Wheel was the first kind of water turbine where a high-pressure nozzle from which the water originated was aimed slightly off-center to the cups that caught the water, allowing the energy created by water's splashing not to be wasted. By the 1890s, more than 300 Knight Wheels had been produced and were in widespread use across the Western United States.
