41 Parry, George
SUBJECT AREA: Metallurgy[br]fl. 1800–1850 Wales[br]Welsh ironmaker and inventor of the bell and hopper for blastfurnaces.[br]Until the mid-nineteenth century, blast furnaces were open at the top to facilitate loading of the iron ore, fuel and flux (the charge). However, that arrangement allowed the hot gases produced in the furnace to escape, whereas they could have been used to heat boilers or the incoming air blast. Attempts had been made to capture the fugitive gases, but they had all failed until George Parry devised his bell and hopper equipment for dosing the throat or top of the furnace. He fixed an inverted cone or hopper inside the throat and arranged inside it a cast-iron bell that could be raised or lowered. When in the raised position, it was in contact with the underside of the hopper, thus sealing the furnace. The hot gases could then be led off through a large pipe to do useful work. The charge was dropped onto the bell, and when enough had accumulated there the bell was lowered, allowing the charge to fall into the furnace. The gas escaped only for the brief period that the bell was lowered. The advantages of this arrangement were soon realized by other ironmasters and it was quite rapidly, and then generally, adopted. The device was still in use in the 1990s, with modifications.[br]Bibliography1858, "On the principal causes of derangements in blast furnaces", Proceedings of the South Wales Institute of Engineers 1:26–39 (describes his improvements to the blast furnace), 28 ff.

55 Curr, John
[br]b. 1756 Kyo, near Lanchester, or in Greenside, near Ryton-on-Tyne, Durham, Englandd. 27 January 1823 Sheffield, England[br]English coal-mine manager and engineer, inventor of flanged, cast-iron plate rails.[br]The son of a "coal viewer", Curr was brought up in the West Durham colliery district. In 1777 he went to the Duke of Norfolk's collieries at Sheffield, where in 1880 he was appointed Superintendent. There coal was conveyed underground in baskets on sledges: Curr replaced the wicker sledges with wheeled corves, i.e. small four-wheeled wooden wagons, running on "rail-roads" with cast-iron rails and hauled from the coal-face to the shaft bottom by horses. The rails employed hitherto had usually consisted of plates of iron, the flange being on the wheels of the wagon. Curr's new design involved flanges on the rails which guided the vehicles, the wheels of which were unflanged and could run on any hard surface. He appears to have left no precise record of the date that he did this, and surviving records have been interpreted as implying various dates between 1776 and 1787. In 1787 John Buddle paid tribute to the efficiency of the rails of Curr's type, which were first used for surface transport by Joseph Butler in 1788 at his iron furnace at Wingerworth near Chesterfield: their use was then promoted widely by Benjamin Outram, and they were adopted in many other English mines. They proved serviceable until the advent of locomotives demanded different rails.In 1788 Curr also developed a system for drawing a full corve up a mine shaft while lowering an empty one, with guides to separate them. At the surface the corves were automatically emptied by tipplers. Four years later he was awarded a patent for using double ropes for lifting heavier loads. As the weight of the rope itself became a considerable problem with the increasing depth of the shafts, Curr invented the flat hemp rope, patented in 1798, which consisted of several small round ropes stitched together and lapped upon itself in winding. It acted as a counterbalance and led to a reduction in the time and cost of hoisting: at the beginning of a run the loaded rope began to coil upon a small diameter, gradually increasing, while the unloaded rope began to coil off a large diameter, gradually decreasing.Curr's book The Coal Viewer (1797) is the earliest-known engineering work on railway track and it also contains the most elaborate description of a Newcomen pumping engine, at the highest state of its development. He became an acknowledged expert on construction of Newcomen-type atmospheric engines, and in 1792 he established a foundry to make parts for railways and engines.Because of the poor financial results of the Duke of Norfolk's collieries at the end of the century, Curr was dismissed in 1801 despite numerous inventions and improvements which he had introduced. After his dismissal, six more of his patents were concerned with rope-making: the one he gained in 1813 referred to the application of flat ropes to horse-gins and perpendicular drum-shafts of steam engines. Curr also introduced the use of inclined planes, where a descending train of full corves pulled up an empty one, and he was one of the pioneers employing fixed steam engines for hauling. He may have resided in France for some time before his death.[br]Bibliography1788. British patent no. 1,660 (guides in mine shafts).1789.

58 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 -
59 Trevithick, Richard
[br]b. 13 April 1771 Illogan, Cornwall, Englandd. 22 April 1833 Dartford, Kent, England[br]English engineer, pioneer of non-condensing steam-engines; designed and built the first locomotives.[br]Trevithick's father was a tin-mine manager, and Trevithick himself, after limited formal education, developed his immense engineering talent among local mining machinery and steam-engines and found employment as a mining engineer. Tall, strong and high-spirited, he was the eternal optimist.About 1797 it occurred to him that the separate condenser patent of James Watt could be avoided by employing "strong steam", that is steam at pressures substantially greater than atmospheric, to drive steam-engines: after use, steam could be exhausted to the atmosphere and the condenser eliminated. His first winding engine on this principle came into use in 1799, and subsequently such engines were widely used. To produce high-pressure steam, a stronger boiler was needed than the boilers then in use, in which the pressure vessel was mounted upon masonry above the fire: Trevithick designed the cylindrical boiler, with furnace tube within, from which the Cornish and later the Lancashire boilers evolved.Simultaneously he realized that high-pressure steam enabled a compact steam-engine/boiler unit to be built: typically, the Trevithick engine comprised a cylindrical boiler with return firetube, and a cylinder recessed into the boiler. No beam intervened between connecting rod and crank. A master patent was taken out.Such an engine was well suited to driving vehicles. Trevithick built his first steam-carriage in 1801, but after a few days' use it overturned on a rough Cornish road and was damaged beyond repair by fire. Nevertheless, it had been the first self-propelled vehicle successfully to carry passengers. His second steam-carriage was driven about the streets of London in 1803, even more successfully; however, it aroused no commercial interest. Meanwhile the Coalbrookdale Company had started to build a locomotive incorporating a Trevithick engine for its tramroads, though little is known of the outcome; however, Samuel Homfray's ironworks at Penydarren, South Wales, was already building engines to Trevithick's design, and in 1804 Trevithick built one there as a locomotive for the Penydarren Tramroad. In this, and in the London steam-carriage, exhaust steam was turned up the chimney to draw the fire. On 21 February the locomotive hauled five wagons with 10 tons of iron and seventy men for 9 miles (14 km): it was the first successful railway locomotive.Again, there was no commercial interest, although Trevithick now had nearly fifty stationary engines completed or being built to his design under licence. He experimented with one to power a barge on the Severn and used one to power a dredger on the Thames. He became Engineer to a project to drive a tunnel beneath the Thames at Rotherhithe and was only narrowly defeated, by quicksands. Trevithick then set up, in 1808, a circular tramroad track in London and upon it demonstrated to the admission-fee-paying public the locomotive Catch me who can, built to his design by John Hazledine and J.U. Rastrick.In 1809, by which date Trevithick had sold all his interest in the steam-engine patent, he and Robert Dickinson, in partnership, obtained a patent for iron tanks to hold liquid cargo in ships, replacing the wooden casks then used, and started to manufacture them. In 1810, however, he was taken seriously ill with typhus for six months and had to return to Cornwall, and early in 1811 the partners were bankrupt; Trevithick was discharged from bankruptcy only in 1814.In the meantime he continued as a steam engineer and produced a single-acting steam engine in which the cut-off could be varied to work the engine expansively by way of a three-way cock actuated by a cam. Then, in 1813, Trevithick was approached by a representative of a company set up to drain the rich but flooded silver-mines at Cerro de Pasco, Peru, at an altitude of 14,000 ft (4,300 m). Low-pressure steam engines, dependent largely upon atmospheric pressure, would not work at such an altitude, but Trevithick's high-pressure engines would. Nine engines and much other mining plant were built by Hazledine and Rastrick and despatched to Peru in 1814, and Trevithick himself followed two years later. However, the war of independence was taking place in Peru, then a Spanish colony, and no sooner had Trevithick, after immense difficulties, put everything in order at the mines then rebels arrived and broke up the machinery, for they saw the mines as a source of supply for the Spanish forces. It was only after innumerable further adventures, during which he encountered and was assisted financially by Robert Stephenson, that Trevithick eventually arrived home in Cornwall in 1827, penniless.He petitioned Parliament for a grant in recognition of his improvements to steam-engines and boilers, without success. He was as inventive as ever though: he proposed a hydraulic power transmission system; he was consulted over steam engines for land drainage in Holland; and he suggested a 1,000 ft (305 m) high tower of gilded cast iron to commemorate the Reform Act of 1832. While working on steam propulsion of ships in 1833, he caught pneumonia, from which he died.[br]BibliographyTrevithick took out fourteen patents, solely or in partnership, of which the most important are: 1802, Construction of Steam Engines, British patent no. 2,599. 1808, Stowing Ships' Cargoes, British patent no. 3,172.Further ReadingH.W.Dickinson and A.Titley, 1934, Richard Trevithick.
