Was/is the foundry driven directly from a turbine, or is it hydro-electric, what type of turbine is used, a Pelton wheel, or a Francis type?

The main power for the shop is a Knight water wheel, 42 inch diameter, rated at 35 H.P. It's belted to the lineshafts. The Knight wheel is similar to the Pelton (which it preceded). The main difference is its cups lack the central septum that Pelton's cups have. Water to the wheel comes from a reservoir 400 feet up in elevation. It's regulated to about 120-140 PSI. Samuel Knight designed his wheel in the early 1870's. He had it cast by Campbell & Hall foundry in Sutter Creek and in 1875 bought the foundry and renamed it Knight Foundry.
A common product of the foundry was the Knight Water Motor which consisted of a Knight wheel inside a cast housing. I think there's one shown in the video I posted. Knight designed and built a Knight wheel powered mine hoist. It had two water motors run in opposite directions with a mechanism to give forward and reverse motion to the hoist. Knight also developed a regulating mechanism so that the Knight wheel could be used to generate A.C. power. There was a power plant in the state of Utah that used the Knight wheel.
The Pelton wheel was more efficient than the Knight and eventually supplanted it in the marketplace. There's some thought that if the Knight wheel had prevailed it would have been necessary to move production to a larger plant in a more industrialized city and we would not have been left with this nearly intact late 19th-early 20th century industrial site. Looks like I'm out of room… David
