About This Book

The author offers first-person technical memoirs recounting education, early mechanical projects, and the design, manufacture, and commercialization of control devices and measuring instruments for steam engines, including centrifugal governors and a steam-engine indicator. It chronicles collaborations and conflicts with contemporary firms, engineering experiments, exhibition displays abroad, and practical refinements to engine beds, condensers, and testing apparatus. Interleaved observations address workshop practice, instrument testing, patent dealings, and the evolution of high-speed stationary and marine engines, while diagrams and case studies illustrate performance, manufacturing challenges, and lessons learned.
