68 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.

69 Seguin, Marc
[br]b. 20 April 1786 Annonay, Ardèche, Franced. 24 February 1875 Annonay, Ardèche, France[br]French engineer, inventor of multi-tubular firetube boiler.[br]Seguin trained under Joseph Montgolfier, one of the inventors of the hot-air balloon, and became a pioneer of suspension bridges. In 1825 he was involved in an attempt to introduce steam navigation to the River Rhône using a tug fitted with a winding drum to wind itself upstream along a cable attached to a point on the bank, with a separate boat to transfer the cable from point to point. The attempt proved unsuccessful and was short-lived, but in 1825 Seguin had decided also to seek a government concession for a railway from Saint-Etienne to Lyons as a feeder of traffic to the river. He inspected the Stockton \& Darlington Railway and met George Stephenson; the concession was granted in 1826 to Seguin Frères \& Ed. Biot and two steam locomotives were built to their order by Robert Stephenson \& Co. The locomotives were shipped to France in the spring of 1828 for evaluation prior to construction of others there; each had two vertical cylinders, one each side between front and rear wheels, and a boiler with a single large-diameter furnace tube, with a watertube grate. Meanwhile, in 1827 Seguin, who was still attempting to produce a steamboat powerful enough to navigate the fast-flowing Rhône, had conceived the idea of increasing the heating surface of a boiler by causing the hot gases from combustion to pass through a series of tubes immersed in the water. He was soon considering application of this type of boiler to a locomotive. He applied for a patent for a multi-tubular boiler on 12 December 1827 and carried out numerous experiments with various means of producing a forced draught to overcome the perceived obstruction caused by the small tubes. By May 1829 the steam-navigation venture had collapsed, but Seguin had a locomotive under construction in the workshops of the Lyons-Sain t- Etienne Railway: he retained the cylinder layout of its Stephenson locomotives, but incorporated a boiler of his own design. The fire was beneath the barrel, surrounded by a water-jacket: a single large flue ran towards the front of the boiler, whence hot gases returned via many small tubes through the boiler barrel to a chimney above the firedoor. Draught was provided by axle-driven fans on the tender.Seguin was not aware of the contemporary construction of Rocket, with a multi-tubular boiler, by Robert Stephenson; Rocket had its first trial run on 5 September 1829, but the precise date on which Seguin's locomotive first ran appears to be unknown, although by 20 October many experiments had been carried out upon it. Seguin's concept of a multi-tubular locomotive boiler therefore considerably antedated that of Henry Booth, and his first locomotive was completed about the same date as Rocket. It was from Rocket's boiler, however, rather than from that of Seguin's locomotive, that the conventional locomotive boiler was descended.[br]BibliographyFebruary 1828, French patent no. 3,744 (multi-tubular boiler).1839, De l'Influence des chemins de fer et de l'art de les tracer et de les construire, Paris.Further ReadingF.Achard and L.Seguin, 1928, "Marc Seguin and the invention of the tubular boiler", Transactions of the Newcomen Society 7 (traces the chronology of Seguin's boilers).——1928, "British railways of 1825 as seen by Marc Seguin", Transactions of the Newcomen Society 7.J.B.Snell, 1964, Early Railways, London: Weidenfeld \& Nicolson.J.-M.Combe and B.Escudié, 1991, Vapeurs sur le Rhône, Lyons: Presses Universitaires de Lyon.PJGR
