The Corliss Engine
George H. Corliss
Born in North Easton, Washington County, New York, George H. Corliss started out to work in a general store. At twenty-one he was the proprietor of his own store. It was an incident which happened there that set him forth on a career as an inventor. A customer complained of a pair of boots which ripped at the seams. Corliss thought there ought to be a better way to sew and in the process of trying to find it, invented a sewing machine in 1843, three years before Elias Howe received his patent. That was his first step as an inventor and it was followed by many other inventions.
The Corliss steam engine improvements, at the time of their invention and for many years thereafter, represented the most effective device ever designed for economizing in the use of steam and regulating the steadiness of a steam engine’s power and speed. These were essential steps if man was to harness the power of steam and turn it to practical use.
Before the advent of the Corliss engine, those engines which were available were very wasteful in their use of fuel to produce steam and its resultant power. They were also unable to maintain even speeds in driving factory machinery and other units. This uneven flow of power was a serious handicap to those who wanted to use steam to turn the wheels of industry.
The secret of the efficiency of the Corliss engine lay in its most distinctive feature ... the Corliss cut-off valve gear. The cut-off was automatically controlled by the governor regardless of power variations and without any slowing in speed. This was fundamentally responsible for the Corliss’ efficiency and savings in fuel. So efficient was the engine that the inventor often agreed to sell his product under an agreement that the saving in fuel cost by the end of a certain period would be its price. In one case, after the engine had run through the stated period of two years, the purchaser was glad to pay twice the list price rather than the much higher amount represented by actual savings.
The Corliss engine has played no small part in the development of Dayton industry. Two such engines were used by The National Cash Register Company for almost fifty years. One of these has been placed in Carillon Park. In the next few pages this faithful worker for industrial progress tells some of its experiences.
