18 Smeaton, John
SUBJECT AREA: Civil engineering, Mechanical, pneumatic and hydraulic engineering, Steam and internal combustion engines[br]b. 8 June 1724 Austhorpe, near Leeds, Yorkshire, Englandd. 28 October 1792 Austhorpe, near Leeds, Yorkshire, England[br]English mechanical and civil engineer.[br]As a boy, Smeaton showed mechanical ability, making for himself a number of tools and models. This practical skill was backed by a sound education, probably at Leeds Grammar School. At the age of 16 he entered his father's office; he seemed set to follow his father's profession in the law. In 1742 he went to London to continue his legal studies, but he preferred instead, with his father's reluctant permission, to set up as a scientific instrument maker and dealer and opened a shop of his own in 1748. About this time he began attending meetings of the Royal Society and presented several papers on instruments and mechanical subjects, being elected a Fellow in 1753. His interests were turning towards engineering but were informed by scientific principles grounded in careful and accurate observation.In 1755 the second Eddystone lighthouse, on a reef some 14 miles (23 km) off the English coast at Plymouth, was destroyed by fire. The President of the Royal Society was consulted as to a suitable engineer to undertake the task of constructing a new one, and he unhesitatingly suggested Smeaton. Work began in 1756 and was completed in three years to produce the first great wave-swept stone lighthouse. It was constructed of Portland stone blocks, shaped and pegged both together and to the base rock, and bonded by hydraulic cement, scientifically developed by Smeaton. It withstood the storms of the English Channel for over a century, but by 1876 erosion of the rock had weakened the structure and a replacement had to be built. The upper portion of Smeaton's lighthouse was re-erected on a suitable base on Plymouth Hoe, leaving the original base portion on the reef as a memorial to the engineer.The Eddystone lighthouse made Smeaton's reputation and from then on he was constantly in demand as a consultant in all kinds of engineering projects. He carried out a number himself, notably the 38 mile (61 km) long Forth and Clyde canal with thirty-nine locks, begun in 1768 but for financial reasons not completed until 1790. In 1774 he took charge of the Ramsgate Harbour works.On the mechanical side, Smeaton undertook a systematic study of water-and windmills, to determine the design and construction to achieve the greatest power output. This work issued forth as the paper "An experimental enquiry concerning the natural powers of water and wind to turn mills" and exerted a considerable influence on mill design during the early part of the Industrial Revolution. Between 1753 and 1790 Smeaton constructed no fewer than forty-four mills.Meanwhile, in 1756 he had returned to Austhorpe, which continued to be his home base for the rest of his life. In 1767, as a result of the disappointing performance of an engine he had been involved with at New River Head, Islington, London, Smeaton began his important study of the steam-engine. Smeaton was the first to apply scientific principles to the steam-engine and achieved the most notable improvements in its efficiency since its invention by Newcomen, until its radical overhaul by James Watt. To compare the performance of engines quantitatively, he introduced the concept of "duty", i.e. the weight of water that could be raised 1 ft (30 cm) while burning one bushel (84 lb or 38 kg) of coal. The first engine to embody his improvements was erected at Long Benton colliery in Northumberland in 1772, with a duty of 9.45 million pounds, compared to the best figure obtained previously of 7.44 million pounds. One source of heat loss he attributed to inaccurate boring of the cylinder, which he was able to improve through his close association with Carron Ironworks near Falkirk, Scotland.[br]Principal Honours and DistinctionsFRS 1753.Bibliography1759, "An experimental enquiry concerning the natural powers of water and wind to turn mills", Philosophical Transactions of the Royal Society.Towards the end of his life, Smeaton intended to write accounts of his many works but only completed A Narrative of the Eddystone Lighthouse, 1791, London.Further ReadingS.Smiles, 1874, Lives of the Engineers: Smeaton and Rennie, London.

20 Wolseley, Frederick York
[br]b. 1837 Co. Dublin, Irelandd. 1899 England[br]Irish inventor who developed the first practical sheep shears and was also involved in the development of the car which bore his name.[br]The credit for the first design of sheep shears lies with James Higham, who patented the idea in 1868. However, its practical and commercial success lay in the work of a number of people, to each of whom Frederick Wolseley provides the connecting link.One of three brothers, he emigrated to Australia in 1854 and worked in New South Wales for five years. In 1867 he produced a working model of mechanical sheep shears, but it took a further five years before he actually produced a machine, whilst working as Manager of a sheep station in Victoria. In the intervening period it is possible that he visited America and Britain. On returning to Australia in 1872 he and Robert Savage produced another working model in a workshop in Melbourne. Four years later, by which time Wolseley had acquired the "Euroka" sheep station at Walgett, they tested the model and in 1877 acquired joint patent rights. The machine was not successful, and in 1884 another joint patent, this time with Robert Pickup, was taken out on a cog-gear universal joint. Development was to take several more years, during which a highly skilled blacksmith by the name of George Gray joined the team. It is likely that he was the first person to remove a fleece from a sheep mechanically. Finally, the last to be involved in the development of the shears was another Englishman, John Howard, who emigrated to Australia in 1883 with the intention of developing a shearing machine based on his knowledge of existing horse clippers. Wolseley purchased Howard's patent rights and gave him a job. The first public demonstration of the shears was held at the wool stores of Goldsborough \& Co. of Melbourne. Although the hand shearers were faster, when the three sheep that had been clipped by them were re-shorn using the mechanical machine, a further 2 lb (900 g) of wool was removed.Wolseley placed the first manufacturing order with A.P.Parks, who employed a young Englishman by the name of Herbert Austin. A number of improvements to the design were suggested by Austin, who acquired patents and assigned them to Wolseley in 1895 in return for shares in the company. Austin returned to England to run the Wolseley factory in Birmingham. He also built there the first car to carry the Wolseley name, and subsequently opened a car factory carrying his own name.Wolseley resigned as Managing Director of the company in 1894 and died five years later.[br]Further ReadingF.Wheelhouse, 1966, Digging Stock to Rotary Hoe: Men and Machines in Rural Australia (provides a detailed account of Wolseley's developments).APBiographical history of technology > Wolseley, Frederick York
