Though other men had built steam turbines,it was Gustav De Laval, of Sweden, who, in1883, made it a practical success. He did thisby driving a cream separator with it. His tur-bine is a highly developed Brancas impulse en-gine having a single wheel mounted on a flexibleshaft. The small ones run at the enormouslyhigh speed of 30,000 revolutions per minute andthis is slowed down to working speeds by meansof what are called reduction gears. It is shownin Fig. 11. A year after De Laval got out his single wheelturbine, Charles A. Parsons, of England, com-bined the principles of the reaction and impulse The First Engines 19 engines and built the first multiple steam turbine, see Fig. 12, developed 10 horsepower when running at 18,000 revolutions per.
