4 Lombe, John
SUBJECT AREA: Textiles[br]b. c. 1693 probably Norwich, Englandd. 20 November 1722 Derby, England[br]English creator of the first successful powered textile mill in Britain.[br]John Lombe's father, Henry Lombe, was a worsted weaver who married twice. John was the second son of the second marriage and was still a baby when his father died in 1695. John, a native of the Eastern Counties, was apprenticed to a trade and employed by Thomas Cotchett in the erection of Cotchett's silk mill at Derby, which soon failed however. Lombe went to Italy, or was sent there by his elder half-brother, Thomas, to discover the secrets of their throwing machinery while employed in a silk mill in Piedmont. He returned to England in 1716 or 1717, bringing with him two expert Italian workmen.Thomas Lombe was a prosperous London merchant who financed the construction of a new water-powered silk mill at Derby which is said to have cost over £30,000. John arranged with the town Corporation for the lease of the island in the River Derwent, where Cotchett had erected his mill. During the four years of its construction, John first set up the throwing machines in other parts of the town. The machines were driven manually there, and their product helped to defray the costs of the mill. The silk-throwing machine was very complex. The water wheel powered a horizontal shaft that was under the floor and on which were placed gearwheels to drive vertical shafts upwards through the different floors. The throwing machines were circular, with the vertical shafts running through the middle. The doubled silk threads had previously been wound on bobbins which were placed on spindles with wire flyers at intervals around the outer circumference of the machine. The bobbins were free to rotate on the spindles while the spindles and flyers were driven by the periphery of a horizontal wheel fixed to the vertical shaft. Another horizontal wheel set a little above the first turned the starwheels, to which were attached reels for winding the silk off the bobbins below. Three or four sets of these spindles and reels were placed above each other on the same driving shaft. The machine was very complicated for the time and must have been expensive to build and maintain.John lived just long enough to see the mill in operation, for he died in 1722 after a painful illness said to have been the result of poison administered by an Italian woman in revenge for his having stolen the invention and for the injury he was causing the Italian trade. The funeral was said to have been the most superb ever known in Derby.[br]Further ReadingSamuel Smiles, 1890, Men of Invention and Industry, London (probably the only biography of John Lombe).Rhys Jenkins, 1933–4, "Historical notes on some Derbyshire industries", Transactions of the Newcomen Society 14 (provides an acount of John Lombe and his part in the enterprise at Derby).R.L.Hills, 1970, Power in the Industrial Revolution, Manchester (briefly covers the development of early silk-throwing mills).W.English, 1969, The Textile Industry, London (includes a chapter on "Lombe's Silk Machine").P.Barlow, 1836, Treatise of Manufactures and Machinery of Great Britain, London (describes Lombe's mill and machinery, but it is not known how accurate the account may be).RLH -
5 Stevens, John
[br]b. 1749 New York, New York, USAd. 6 March 1838 Hoboken, New Jersey, USA[br]American pioneer of steamboats and railways.[br]Stevens, a wealthy landowner with an estate at Hoboken on the Hudson River, had his attention drawn to the steamboat of John Fitch in 1786, and thenceforth devoted much of his time and fortune to developing steamboats and mechanical transport. He also had political influence and it was at his instance that Congress in 1790 passed an Act establishing the first patent laws in the USA. The following year Stevens was one of the first recipients of a US patent. This referred to multi-tubular boilers, of both watertube and firetube types, and antedated by many years the work of both Henry Booth and Marc Seguin on the latter.A steamboat built in 1798 by John Stevens, Nicholas J.Roosevelt and Stevens's brother-in-law, Robert R.Livingston, in association was unsuccessful, nor was Stevens satisfied with a boat built in 1802 in which a simple rotary steam-en-gine was mounted on the same shaft as a screw propeller. However, although others had experimented earlier with screw propellers, when John Stevens had the Little Juliana built in 1804 he produced the first practical screw steamboat. Steam at 50 psi (3.5 kg/cm2) pressure was supplied by a watertube boiler to a single-cylinder engine which drove two contra-rotating shafts, upon each of which was mounted a screw propeller. This little boat, less than 25 ft (7.6 m) long, was taken backwards and forwards across the Hudson River by two of Stevens's sons, one of whom, R.L. Stevens, was to help his father with many subsequent experiments. The boat, however, was ahead of its time, and steamships were to be driven by paddle wheels until the late 1830s.In 1807 John Stevens declined an invitation to join with Robert Fulton and Robert R.Living-ston in their development work, which culminated in successful operation of the PS Clermont that summer; in 1808, however, he launched his own paddle steamer, the Phoenix. But Fulton and Livingston had obtained an effective monopoly of steamer operation on the Hudson and, unable to reach agreement with them, Stevens sent Phoenix to Philadelphia to operate on the Delaware River. The intervening voyage over 150 miles (240 km) of open sea made Phoenix the first ocean-going steamer.From about 1810 John Stevens turned his attention to the possibilities of railways. He was at first considered a visionary, but in 1815, at his instance, the New Jersey Assembly created a company to build a railway between the Delaware and Raritan Rivers. It was the first railway charter granted in the USA, although the line it authorized remained unbuilt. To demonstrate the feasibility of the steam locomotive, Stevens built an experimental locomotive in 1825, at the age of 76. With flangeless wheels, guide rollers and rack-and-pinion drive, it ran on a circular track at his Hoboken home; it was the first steam locomotive to be built in America.[br]Bibliography1812, Documents Tending to Prove the Superior Advantages of Rail-ways and Steam-carriages over Canal Navigation.He took out patents relating to steam-engines in the USA in 1791, 1803, and 1810, and in England, through his son John Cox Stevens, in 1805.Further ReadingH.P.Spratt, 1958, The Birth of the Steamboat, Charles Griffin (provides technical details of Stevens's boats).J.T.Flexner, 1978, Steamboats Come True, Boston: Little, Brown (describes his work in relation to that of other steamboat pioneers).J.R.Stover, 1961, American Railroads, Chicago: University of Chicago Press.Transactions of the Newcomen Society (1927) 7: 114 (discusses tubular boilers).J.R.Day and B.G.Wilson, 1957, Unusual Railways, F.Muller (discusses Stevens's locomotive).PJGR
