One of the great Victorian engineers, Sir William Fairbairn (1789-1874) had started his career as a millwright's apprentice, going on to become a civil engineer, a designer of industrial machinery and an expert on the failure of materials and structures. The present work distils a lifetime's experience of mechanical design into two highly illustrated parts. First published in 1861 and 1863, they are here reissued in a single volume. Part 1 gives a general overview of mechanisms such as gears, cranks and cams, and then moves on to the design of prime movers: waterwheels and turbines, steam engines and boilers, and windmills. Part 2 covers the design of mechanisms in more detail, and discusses power transmissions and their components: shafts, gears, bearings, couplings and so on. Lastly, Fairbairn gives overviews of the most important types of industrial mill - including cotton, wool, paper, iron and gunpowder - and their machinery.
