2 Ferguson, Harry
SUBJECT AREA: Agricultural and food technology[br]b. 4 November 1884 County Down, Irelandd. 25 October 1960 England[br]Irish engineer who developed a tractor hydraulic system for cultivation equipment, and thereby revolutionized tractor design.[br]Ferguson's father was a small farmer who expected his son to help on the farm from an early age. As a result he received little formal education, and on leaving school joined his brother in a backstreet workshop in Belfast repairing motor bikes. By the age of 19 he had built his own bike and began hill-climbing competitions and racing. His successes in these ventures gained useful publicity for the workshop. In 1907 he built his own car and entered it into competitions, and in 1909 became the first person in Britain to build and fly a machine that was heavier than air.On the outbreak of the First World War he was appointed by the Irish Department of Agriculture to supervise the operation and maintenance of all farm tractors. His experiences convinced him that even the Ford tractor and the implements available for it were inadequate for the task, and he began to experiment with his own plough designs. The formation of the Ferguson-Sherman Corporation resulted in the production of thousands of the ploughs he had designed for the Ford tractor, but in 1928 Ford discontinued production of tractors, and Ferguson returned to Ireland. He immediately began to design his own tractor. Six years of development led to the building of a prototype that weighed only 16 cwt (813kg). In 1936 David Brown of Huddersfield, Yorkshire, began production of these tractors for Ferguson, but the partnership was not wholly successful and was dissolved after three years. In 1939 Ferguson and Ford reached their famous "Handshake agreement", in which no formal contract was signed, and the mass production of the Ford Ferguson system tractors began that year. During the next nine years 300,000 tractors and a million implements were produced under this agreement. However, on the death of Henry Ford the company began production, under his son, of their own tractor. Ferguson returned to the UK and negotiated a deal with the Standard Motor Company of Coventry for the production of his tractor. At the same time he took legal action against Ford, which resulted in that company being forced to stop production and to pay damages amounting to US$9.5 million.Aware that his equipment would only operate when set up properly, Ferguson established a training school at Stoneleigh in Warwickshire which was to be a model for other manufacturers. In 1953, by amicable agreement, Ferguson amalgamated with the Massey Harris Company to form Massey Ferguson, and in so doing added harvesting machinery to the range of equipment produced. A year later he disposed of his shares in the new company and turned his attention again to the motor car. Although a number of experimental cars were produced, there were no long-lasting developments from this venture other than a four-wheel-drive system based on hydraulics; this was used by a number of manufacturers on occasional models. Ferguson's death heralded the end of these developments.[br]Principal Honours and DistinctionsHonorary DSc Queen's University, Belfast, 1948.Further ReadingC.Murray, 1972, Harry Ferguson, Inventor and Pioneer.

3 Bedson, George
SUBJECT AREA: Metallurgy[br]b. 3 November 1820 Sutton Coldfield, Warwickshire, Englandd. 12 December 1884 Manchester (?), England[br]English metallurgist, inventor of the continuous rolling mill.[br]He acquired a considerable knowledge of wire-making in his father's works before he took a position in 1839 at the works of James Edleston at Warrington. From there, in 1851, he went to Manchester as Manager of Richard Johnson \& Sons' wire mill, where he remained for the rest of his life. It was there that he initiated several important improvements in the manufacture of wire. These included a system of circulating puddling furnace water bottoms and sides, and a galvanizing process. His most important innovation, however, was the continuous mill for producing iron rod for wiredrawing. Previously the red-hot iron billets had to be handled repeatedly through a stand or set of rolls to reduce the billet to the required shape, with time and heat being lost at each handling. In Bedson's continuous mill, the billet entered the first of a succession of stands placed as closely to each other as possible and emerged from the final one as rod suitable for wiredrawing, without any intermediate handling. A second novel feature was that alternate rolls were arranged vertically to save turning the piece manually through a right angle. That improved the quality as well as the speed of production. Bedson's first continuous mill was erected in Manchester in 1862 and had sixteen stands in tandem. A mill on this principle had been patented the previous year by Charles While of Pontypridd, South Wales, but it was Bedson who made it work and brought it into use commercially. A difficult problem to overcome was that as the piece being rolled lengthened, its speed increased, so that each pair of rolls had to increase correspondingly. The only source of power was a steam engine working a single drive shaft, but Bedson achieved the greater speeds by using successively larger gear-wheels at each stand.Bedson's first mill was highly successful, and a second one was erected at the Manchester works; however, its application was limited to the production of small bars, rods and sections. Nevertheless, Bedson's mill established an important principle of rolling-mill design that was to have wider applications in later years.[br]Further ReadingObituary, 1884, Journal of the Iron and Steel Institute 27:539–40.
