2 Priestman, William Dent
SUBJECT AREA: Steam and internal combustion engines[br]b. 23 August 1847 Sutton, Hull, Englandd. 7 September 1936 Hull, England[br]English oil engine pioneer.[br]William was the second son and one of eleven children of Samuel Priestman, who had moved to Hull after retiring as a corn miller in Kirkstall, Leeds, and who in retirement had become a director of the North Eastern Railway Company. The family were strict Quakers, so William was sent to the Quaker School in Bootham, York. He left school at the age of 17 to start an engineering apprenticeship at the Humber Iron Works, but this company failed so the apprenticeship was continued with the North Eastern Railway, Gateshead. In 1869 he joined the hydraulics department of Sir William Armstrong \& Company, Newcastle upon Tyne, but after a year there his father financed him in business at a small, run down works, the Holderness Foundry, Hull. He was soon joined by his brother, Samuel, their main business being the manufacture of dredging equipment (grabs), cranes and winches. In the late 1870s William became interested in internal combustion engines. He took a sublicence to manufacture petrol engines to the patents of Eugène Etève of Paris from the British licensees, Moll and Dando. These engines operated in a similar manner to the non-compression gas engines of Lenoir. Failure to make the two-stroke version of this engine work satisfactorily forced him to pay royalties to Crossley Bros, the British licensees of the Otto four-stroke patents.Fear of the dangers of petrol as a fuel, reflected by the associated very high insurance premiums, led William to experiment with the use of lamp oil as an engine fuel. His first of many patents was for a vaporizer. This was in 1885, well before Ackroyd Stuart. What distinguished the Priestman engine was the provision of an air pump which pressurized the fuel tank, outlets at the top and bottom of which led to a fuel atomizer injecting continuously into a vaporizing chamber heated by the exhaust gases. A spring-loaded inlet valve connected the chamber to the atmosphere, with the inlet valve proper between the chamber and the working cylinder being camoperated. A plug valve in the fuel line and a butterfly valve at the inlet to the chamber were operated, via a linkage, by the speed governor; this is believed to be the first use of this method of control. It was found that vaporization was only partly achieved, the higher fractions of the fuel condensing on the cylinder walls. A virtue was made of this as it provided vital lubrication. A starting system had to be provided, this comprising a lamp for preheating the vaporizing chamber and a hand pump for pressurizing the fuel tank.Engines of 2–10 hp (1.5–7.5 kW) were exhibited to the press in 1886; of these, a vertical engine was installed in a tram car and one of the horizontals in a motor dray. In 1888, engines were shown publicly at the Royal Agricultural Show, while in 1890 two-cylinder vertical marine engines were introduced in sizes from 2 to 10 hp (1.5–7.5 kW), and later double-acting ones up to some 60 hp (45 kW). First, clutch and gearbox reversing was used, but reversing propellers were fitted later (Priestman patent of 1892). In the same year a factory was established in Philadelphia, USA, where engines in the range 5–20 hp (3.7–15 kW) were made. Construction was radically different from that of the previous ones, the bosses of the twin flywheels acting as crank discs with the main bearings on the outside.On independent test in 1892, a Priestman engine achieved a full-load brake thermal efficiency of some 14 per cent, a very creditable figure for a compression ratio limited to under 3:1 by detonation problems. However, efficiency at low loads fell off seriously owing to the throttle governing, and the engines were heavy, complex and expensive compared with the competition.Decline in sales of dredging equipment and bad debts forced the firm into insolvency in 1895 and receivers took over. A new company was formed, the brothers being excluded. However, they were able to attend board meetings, but to exert no influence. Engine activities ceased in about 1904 after over 1,000 engines had been made. It is probable that the Quaker ethics of the brothers were out of place in a business that was becoming increasingly cut-throat. William spent the rest of his long life serving others.[br]Further ReadingC.Lyle Cummins, 1976, Internal Fire, Carnot Press.C.Lyle Cummins and J.D.Priestman, 1985, "William Dent Priestman, oil engine pioneer and inventor: his engine patents 1885–1901", Proceedings of the Institution ofMechanical Engineers 199:133.Anthony Harcombe, 1977, "Priestman's oil engine", Stationary Engine Magazine 42 (August).JBBiographical history of technology > Priestman, William Dent

3 Reynolds, Richard
[br]b. 1 November 1735 Bristol, Englandd. 10 September 1816 Cheltenham, Gloucestershire, England[br]English ironmaster who invented iron rails.[br]Reynolds was born into a Quaker family, his father being an iron merchant and a considerable customer for the products of the Darbys (see Abraham Darby) of Coalbrookdale in Shropshire. After education at a Quaker boarding school in Pickwick, Wiltshire, Reynolds was apprenticed to William Fry, a grocer of Bristol, from whom he would have learned business methods. The year before the expiry of his apprenticeship in 1757, Reynolds was being sent on business errands to Coalbrookdale. In that year he met and married Hannah Darby, the daughter of Abraham Darby II. At the same time, he acquired a half-share in the Ketley ironworks, established not long before, in 1755. There he supervised not only the furnaces at Ketley and Horsehay and the foundry, but also the extension of the railway, linking this site to Coalbrookdale itself.On the death of Abraham Darby II in 1763, Reynolds took charge of the whole works during the minority of Abraham Darby III. During this period, the most notable development was the introduction by the Cranage brothers of a new way of converting pig-iron to wrought iron, a process patented in 1766 that used coal in a reverberatory furnace. This, with other processes for the same purpose, remained in use until superseded by the puddling process patented by Henry Cort in 1783 and 1784. Reynolds's most important innovation was the introduction of cast-iron rails in 1767 on the railway around Coalbrookdale. A useful network had been in operation for some time with wooden rails, but these wore out quickly and were expensive to maintain. Reynolds's iron rails were an immediate improvement, and some 20 miles (32 km) were laid within a short time. In 1768 Abraham Darby III was able to assume control of the Coalbrookdale works, but Reynolds had been extending his own interest in other ironworks and various other concerns, earning himself considerable wealth. When Darby was oppressed with loan repayments, Reynolds bought the Manor of Madely, which made him Landlord of the Coalbrookdale Company; by 1780 he was virtually banker to the company.[br]Further ReadingH.M.Rathbone, 1852, Letters of Richard Reynolds with a Memoir of his Life, London.A.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (contains many details of Reynolds's life).LRD -

5 Fowler, John
SUBJECT AREA: Civil engineering[br]b. 11 July 1826 Melksham, Wiltshire, Englandd. 4 December 1864 Ackworth, Yorkshire, England[br]English engineer and inventor who developed a steam-powered system of mole land drainage, and a two-engined system of land cultivation, founding the Steam Plough Works in Leeds.[br]The son of a Quaker merchant, John Fowler entered the business of a county corn merchant on leaving school, but he found this dull and left as soon as he came of age, joining the Middlesbrough company of Gilkes, Wilson \& Hopkins, railway locomotive manufacturers. In 1849, at the age of 23, Fowler visited Ireland and was so distressed by the state of Irish agriculture that he determined to develop a system to deal with the drainage of land. He designed an implement which he patented in 1850 after a period of experimentation. It was able to lay wooden pipes to a depth of two feet, and was awarded the Silver Medal at the 1850 Royal Agriculture Show. By 1854, using a steam engine made by Clayton \& Shuttleworth, he had applied steam power to his invention and gained another award that year at the Royal Show. The following year he turned his attention to steam ploughing. He first developed a single-engined system that used a double windlass with which to haul a plough backwards and forwards across fields. In 1856 he patented his balance plough, and the following year he read a paper to the Institution of Mechanical Engineers at their Birmingham premises, describing the system. In 1858 he won the Royal Agricultural Society award with a plough built for him by Ransomes. Fowler founded the Steam Plough Works in Leeds and in 1862 production began in partnership with William Watson Hewitson. Within two years they were producing the first of a series of engines which were to make the name Fowler known worldwide. John Fowler saw little of his success because he died in 1864 at his Yorkshire home as a result of tetanus contracted after a riding accident.[br]Further ReadingM.Lane, 1980, The Story of the Steam Plough Works, Northgate Publishing (provides biographical details of John Fowler, but is mostly concerned with the company that he founded).AP
