10 Booth, Hubert Cecil
SUBJECT AREA: Civil engineering, Domestic appliances and interiors, Mechanical, pneumatic and hydraulic engineering, Ports and shipping[br]b. 1871 Gloucester, England d. 1955[br]English mechanical, civil and construction engineer best remembered as the inventor of the vacuum cleaner.[br]As an engineer Booth contributed to the design of engines for Royal Navy battleships, designed and supervised the erection of a number of great wheels (in Blackpool, Vienna and Paris) and later designed factories and bridges.In 1900 he attended a demonstration, at St Paneras Station in London, of a new form of railway carriage cleaner that was supposed to blow the dirt into a container. It was not a very successful experiment and Booth, having considered the problem carefully, decided that sucking might be better than blowing. He tried out his idea by placing a piece of damp cloth over an upholstered armchair. When he sucked air by mouth through his cloth the dirt upon it was tangible proof of his theory.Various attempts were being made at this time, especially in America, to find a successful cleaner of carpets and upholstery. Booth produced the first truly satisfactory machine, which he patented in 1901, and coined the term "vacuum cleaner". He formed the Vacuum Cleaner Co. (later to become Goblin BVC Ltd) and began to manufacture his machines. For some years the company provided a cleaning service to town houses, using a large and costly vacuum cleaner (the first model cost £350). Painted scarlet, it measured 54×10×42 in. (137×25×110 cm) and was powered by a petrol-driven 5 hp piston engine. It was transported through the streets on a horse-driven van and was handled by a team of operators who parked outside the house to be cleaned. With the aid of several hundred feet of flexible hose extending from the cleaner through the windows into all the rooms, the machine sucked the dirt of decades from the carpets; at the first cleaning the weight of many such carpets was reduced by 50 per cent as the dirt was sucked away.Many attempts were made in Europe and America to produce a smaller and less expensive machine. Booth himself designed the chief British model in 1906, the Trolley- Vac, which was wheeled around the house on a trolley. Still elaborate, expensive and heavy, this machine could, however, be operated inside a room and was powered from an electric light fitting. It consisted of a sophisticated electric motor and a belt-driven rotary vacuum pump. Various hoses and fitments made possible the cleaning of many different surfaces and the dust was trapped in a cloth filter within a small metal canister. It was a superb vacuum cleaner but cost 35 guineas and weighed a hundredweight (50 kg), so it was difficult to take upstairs.Various alternative machines that were cheaper and lighter were devised, but none was truly efficient until a prototype that married a small electric motor to the machine was produced in 1907 in America.[br]Further ReadingThe Story of the World's First Vacuum Cleaner, Leatherhead: BSR (Housewares) Ltd.

11 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.

12 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.
