 of its time. The Corliss engine is widely considered one of the more notable engineering achievements of the 19th century. It provided a reliable, efficient source of industrial power, enabling the expansion of new factories to areas which did not readily possess reliable or abundant water power. Corliss gained international acclaim for his achievements during the late 19th century and is perhaps best known for the Centennial Engine, which was the huge centerpiece of the 1876 Centennial Exposition

. Together they had two children, Maria Louisa and George Frost.

During this time he became more interested in mechanical endeavors. Around 1841, Corliss decided to give his whole attention to these new tasks. In 1842, Corliss obtained a patent on a machine for sewing boots, shoes and heavy leather.

, which at the time was generally regarded as a rather innefficient or supplemental alternative to water power.

Career

In 1848 Corliss entered into a partnership with John Barstow and E.J. Nightingale under the name Corliss, Nightingale & Company. During the same year, the company built the first engine utilizing George's improvements, which except for various technical improvements later on, was essentially the Corliss steam engine

, where the company would expand greatly in the years to follow. By the time of George's death in 1888, the floor space within the plant would cover about five acres, and the company would emloy over 1,000 people.

On March 10, 1849, Corliss was granted US Patent #6162 for his valve gear

. In 1856 the Corliss Steam Engine Company was incorporated with George Corliss as president, and his younger brother, William, as treasurer. William Corliss would go on to develop the Corliss Safe, and form the Corliss Safe Manufacturing Company in Providence.

By 1859, Corliss engines were being exported to Scotland

 for use in cotton mills. By 1864, valves for the engines were being made at Bolton, England. Corliss directed both the business and research sides of this company, and over the years invented many assembly line improvements such as a bevel-gear cutter. Europe eventually became a great purchaser of the Corliss engine and it was copied by the engine builders who placed upon their imitations the name of the American builder.

The dramatic fuel efficiency of the Corliss engine was a major selling point to manufacturers, particularly during the early years. Similar to other engine makers of the day, the Corliss Steam Engine Company often negotiated the selling price of their machines on the projected savings in coal.

Corliss' first wife Phebe died on March 5, 1859. In December, 1866, he married Emily A. Shaw, of Newburyport, Massachusetts

: "A mechanism as beautiful as the human hand. It releases or retains its grasp on the feeding valve, and gives a greater or less dose of steam in nice proportion to each varying want.

Upon the great task of arranging the exposition, he worked with his usual indefatigable energy and it was his suggestion that the Centennial Board of Finance be organized, a body which had no little to do with the insurance of the financial success of the exhibition.

It was also in his own department as engineer that Corliss contributed largely to the success of the great fair, and it was he that supplied, after the plans of all other competitors proved inadequate, the great fourteen hundred horsepower

Horsepower is the name of several units of measurement of power.

. In the matter of his religious belief he was a Congregationalist, and attended the Charles Street Church in Providence from the time of its organization. He was keenly interested in the cause of religion and gave liberally both to his own and to other churches.

Corliss' 1849 patent expired in 1870 after it was extended by U.S. Patent reissue 200 on May 13, 1851 and U.S. Patent reissues 758 and 763 on July 12, 1859. After 1870, numerous other companies began to manufacture Corliss engines. Among them, the William A.

Despite the competition, Corliss would continue to remain active within his company, directing changes to his basic design as market or customer needs dictated.
