The Flyball Governors Feb 17, 2006
On a recent return visit I shot a series of these as portraits. As to what they are? A quick check on the web indicated that they're a feedback mechanism for a steam engine.
The shaft of a flyball governor is spun by a steam engine. As it spins, centrifugal force throws weights outward, moving linkages that slow the machine down. As the shaft slows down, the weights fall, engaging a throttle that speeds the engine up. The flyball governor forces the engine to operate at a constant and consistent speed.
