2 Corliss, George Henry
SUBJECT AREA: Steam and internal combustion engines[br]b. 2 June 1817 Easton, Washington City, New York, USAd. 21 February 1888 USA[br]American inventor of a cut-off mechanism linked to the governor which revolutionized the operation of steam engines.[br]Corliss's father was a physician and surgeon. The son was educated at Greenwich, New York, but while he showed an aptitude for mathematics and mechanics he first of all became a storekeeper and then clerk, bookkeeper, salesperson and official measurer and inspector of the cloth produced at W.Mowbray \& Son. He went to the Castleton Academy, Vermont, for three years and at the age of 21 returned to a store of his own in Greenwich. Complaints about stitching in the boots he sold led him to patent a sewing machine. He approached Fairbanks, Bancroft \& Co., Providence, Rhode Island, machine and steam engine builders, about producing his machine, but they agreed to take him on as a draughtsman providing he abandoned it. Corliss moved to Providence with his family and soon revolutionized the design and construction of steam engines. Although he started working out ideas for his engine in 1846 and completed one in 1848 for the Providence Dyeing, Bleaching and Calendering Company, it was not until March 1849 that he obtained a patent. By that time he had joined John Barstow and E.J.Nightingale to form a new company, Corliss Nightingale \& Co., to build his design of steam-engines. He used paired valves, two inlet and two exhaust, placed on opposite sides of the cylinder, which gave good thermal properties in the flow of steam. His wrist-plate operating mechanism gave quick opening and his trip mechanism allowed the governor to regulate the closure of the inlet valve, giving maximum expansion for any load. It has been claimed that Corliss should rank equally with James Watt in the development of the steam-engine. The new company bought land in Providence for a factory which was completed in 1856 when the Corliss Engine Company was incorporated. Corliss directed the business activities as well as technical improvements. He took out further patents modifying his valve gear in 1851, 1852, 1859, 1867, 1875, 1880. The business grew until well over 1,000 workers were employed. The cylindrical oscillating valve normally associated with the Corliss engine did not make its appearance until 1850 and was included in the 1859 patent. The impressive beam engine designed for the 1876 Centennial Exhibition by E. Reynolds was the product of Corliss's works. Corliss also patented gear-cutting machines, boilers, condensing apparatus and a pumping engine for waterworks. While having little interest in politics, he represented North Providence in the General Assembly of Rhode Island between 1868 and 1870.[br]Further ReadingMany obituaries appeared in engineering journals at the time of his death.

11 Bain, Alexander
[br]b. October 1810 Watten, Scotlandd. 2 January 1877 Kirkintilloch, Scotland[br]Scottish inventor and entrepreneur who laid the foundations of electrical horology and designed an electromagnetic means of transmitting images (facsimile).[br]Alexander Bain was born into a crofting family in a remote part of Scotland. He was apprenticed to a watchmaker in Wick and during that time he was strongly influenced by a lecture on "Heat, sound and electricity" that he heard in nearby Thurso. This lecture induced him to take up a position in Clerkenwell in London, working as a journeyman clockmaker, where he was able to further his knowledge of electricity by attending lectures at the Adelaide Gallery and the Polytechnic Institution. His thoughts naturally turned to the application of electricity to clockmaking, and despite a bitter dispute with Charles Wheatstone over priority he was granted the first British patent for an electric clock. This patent, taken out on 11 January 1841, described a mechanism for an electric clock, in which an oscillating component of the clock operated a mechanical switch that initiated an electromagnetic pulse to maintain the regular, periodic motion. This principle was used in his master clock, produced in 1845. On 12 December of the same year, he patented a means of using electricity to control the operation of steam railway engines via a steam-valve. His earliest patent was particularly far-sighted and anticipated most of the developments in electrical horology that occurred during the nineteenth century. He proposed the use of electricity not only to drive clocks but also to distribute time over a distance by correcting the hands of mechanical clocks, synchronizing pendulums and using slave dials (here he was anticipated by Steinheil). However, he was less successful in putting these ideas into practice, and his electric clocks proved to be unreliable. Early electric clocks had two weaknesses: the battery; and the switching mechanism that fed the current to the electromagnets. Bain's earth battery, patented in 1843, overcame the first defect by providing a reasonably constant current to drive his clocks, but unlike Hipp he failed to produce a reliable switch.The application of Bain's numerous patents for electric telegraphy was more successful, and he derived most of his income from these. They included a patent of 12 December 1843 for a form of fax machine, a chemical telegraph that could be used for the transmission of text and of images (facsimile). At the receiver, signals were passed through a moving band of paper impregnated with a solution of ammonium nitrate and potassium ferrocyanide. For text, Morse code signals were used, and because the system could respond to signals faster than those generated by hand, perforated paper tape was used to transmit the messages; in a trial between Paris and Lille, 282 words were transmitted in less than one minute. In 1865 the Abbé Caselli, a French engineer, introduced a commercial fax service between Paris and Lyons, based on Bain's device. Bain also used the idea of perforated tape to operate musical wind instruments automatically. Bain squandered a great deal of money on litigation, initially with Wheatstone and then with Morse in the USA. Although his inventions were acknowledged, Bain appears to have received no honours, but when towards the end of his life he fell upon hard times, influential persons in 1873 secured for him a Civil List Pension of £80 per annum and the Royal Society gave him £150.[br]Bibliography1841, British patent no. 8,783; 1843, British patent no. 9,745; 1845, British patent no.10,838; 1847, British patent no. 11,584; 1852, British patent no. 14,146 (all for electric clocks).1852, A Short History of the Electric Clocks with Explanation of Their Principles andMechanism and Instruction for Their Management and Regulation, London; reprinted 1973, introd.

12 Murdock (Murdoch), William
[br]b. 21 August 1754 Cumnock, Ayrshire, Scotlandd. 15 November 1839 Handsworth, Birmingham, England[br]Scottish engineer and inventor, pioneer in coal-gas production.[br]He was the third child and the eldest of three boys born to John Murdoch and Anna Bruce. His father, a millwright and joiner, spelled his name Murdock on moving to England. He was educated for some years at Old Cumnock Parish School and in 1777, with his father, he built a "wooden horse", supposed to have been a form of cycle. In 1777 he set out for the Soho manufactory of Boulton \& Watt, where he quickly found employment, Boulton supposedly being impressed by the lad's hat. This was oval and made of wood, and young William had turned it himself on a lathe of his own manufacture. Murdock quickly became Boulton \& Watt's representative in Cornwall, where there was a flourishing demand for steam-engines. He lived at Redruth during this period.It is said that a number of the inventions generally ascribed to James Watt are in fact as much due to Murdock as to Watt. Examples are the piston and slide valve and the sun-and-planet gearing. A number of other inventions are attributed to Murdock alone: typical of these is the oscillating cylinder engine which obviated the need for an overhead beam.In about 1784 he planned a steam-driven road carriage of which he made a working model. He also planned a high-pressure non-condensing engine. The model carriage was demonstrated before Murdock's friends and travelled at a speed of 6–8 mph (10–13 km/h). Boulton and Watt were both antagonistic to their employees' developing independent inventions, and when in 1786 Murdock set out with his model for the Patent Office, having received no reply to a letter he had sent to Watt, Boulton intercepted him on the open road near Exeter and dissuaded him from going any further.In 1785 he married Mary Painter, daughter of a mine captain. She bore him four children, two of whom died in infancy, those surviving eventually joining their father at the Soho Works. Murdock was a great believer in pneumatic power: he had a pneumatic bell-push at Sycamore House, his home near Soho. The pattern-makers lathe at the Soho Works worked for thirty-five years from an air motor. He also conceived the idea of a vacuum piston engine to exhaust a pipe, later developed by the London Pneumatic Despatch Company's railway and the forerunner of the atmospheric railway.Another field in which Murdock was a pioneer was the gas industry. In 1791, in Redruth, he was experimenting with different feedstocks in his home-cum-office in Cross Street: of wood, peat and coal, he preferred the last. He designed and built in the backyard of his house a prototype generator, washer, storage and distribution plant, and publicized the efficiency of coal gas as an illuminant by using it to light his own home. In 1794 or 1795 he informed Boulton and Watt of his experimental work and of its success, suggesting that a patent should be applied for. James Watt Junior was now in the firm and was against patenting the idea since they had had so much trouble with previous patents and had been involved in so much litigation. He refused Murdock's request and for a short time Murdock left the firm to go home to his father's mill. Boulton \& Watt soon recognized the loss of a valuable servant and, in a short time, he was again employed at Soho, now as Engineer and Superintendent at the increased salary of £300 per year plus a 1 per cent commission. From this income, he left £14,000 when he died in 1839.In 1798 the workshops of Boulton and Watt were permanently lit by gas, starting with the foundry building. The 180 ft (55 m) façade of the Soho works was illuminated by gas for the Peace of Paris in June 1814. By 1804, Murdock had brought his apparatus to a point where Boulton \& Watt were able to canvas for orders. Murdock continued with the company after the death of James Watt in 1819, but retired in 1830 and continued to live at Sycamore House, Handsworth, near Birmingham.[br]Principal Honours and DistinctionsRoyal Society Rumford Gold Medal 1808.Further ReadingS.Smiles, 1861, Lives of the Engineers, Vol. IV: Boulton and Watt, London: John Murray.H.W.Dickinson and R.Jenkins, 1927, James Watt and the Steam Engine, Oxford: Clarendon Press.J.A.McCash, 1966, "William Murdoch.
