Unlike the Walschaerts and Baker systems, the Southern valve gear dispensed with the combination lever which transmitted some of the crosshead motion to the valves. As valve travels increased this approach would become unsustainable. Courtesy Peter Manning and Allan Wallace. Everyone conversant with the history of the steam engine knows the story of the lazy boy who became tired of operating the valve cocks of a Newcomen pumping engine, connected up the cocks by pieces of string to the engine beam, made it self-acting, and went off to play marbles. none of the books or articles that I have seen gives the angle nor do they tell how to figure it. Because Stephenson’s gear can achieve near perfection in enabling a one-piece valve to supply both ends of a double-acting cylinder equally its design in any one particular case ought to follow a complete and correct procedure, in the knowledge that straying from its basic simplicity will impair its excellence. steam engine (Steam engines) Engines powered by boilers to drive powerful locomotives and other machinery.
