It was the centrifugal governor which brought precision to the application of steam power, and its story can be traced back to 17th century Holland and Christiaan Huygens'' development of both the pendulum clock and system controls for windmills, and governors are still at the heart of sophisticated machinery today – albeit electronic rather than mechanical.Without the centrifugal governor, precise control over the increasingly-complex machinery which has been developed over the past two centuries would not have been possible. It was the first device to give the engineman the control they needed.As machine speed increased, the governor had to evolve to keep pace with the demands for greater precision.Over a hundred British patents were applied for in the nineteenth century alone for ‘improvements’ in governor design, many of which could be fitted, or retro-fitted, to engines from every large manufacturer.Some enginemen, on taking up new appointments – their jobs depending on the precision and consistency of their engine’s operation – would even request that the governor be replaced with their preferred model.This book, the first to deal with the subject, tells the story of the evolution of the original ‘s
