Madeley Wood Company In 1709, the first Abraham Darby rebuilt Coalbrookdale Furnace, and eventually used
coke as his fuel. His business was that of an ironfounder, Darby renewed his lease of the works in 1714, forming a new partnership with John Chamberlain and
Thomas Baylies. They built a second furnace in about 1715, which was intended to be followed up with a furnace in Wales at Dolgûn near
Dolgellau and in
Cheshire taking over
Vale Royal Furnace in 1718. However, Darby died prematurely at
Madeley Court in 1717 – the same year as he began the house
Dale End which became home to succeeding generations of the family in Coalbrookdale – followed quickly by his widow Mary. The partnership was dissolved before Mary's death, Baylies taking over Vale Royal. After Mary's death, Baylies had difficulty extracting his capital. The works then passed to a company led by his fellow
Quaker Thomas Goldney II of
Bristol and managed by
Richard Ford (also a Quaker). Darby's son
Abraham Darby the Younger was brought into the business as an assistant manager when old enough. The company's main business was producing
cast-iron goods. Molten iron for this foundry work was not only produced from the blast furnaces, but also by remelting
pig iron in air furnaces, a variant of the
reverberatory furnace. The Company also became early suppliers of cylinders for
Newcomen atmospheric engines from 1723, with upgraded boring facilities in 1734 allowing them to bore larger cylinders reaching 60 inches diameter by 1748 and later 70 inch diameter. They installed their own Newcomen engine in 1743 as a
water-returning engine, which could be used when the water supply was low to pump water from below the waterwheel to the pond above it. From 1720, the Company operated a forge at Coalbrookdale but this was not profitable. In about 1754, renewed experiments took place with the application of coke
pig iron to the production of
bar iron in
charcoal finery forges. This proved to be a success, and led to the partners building new furnaces at
Horsehay and
Ketley. This was the beginning of a great expansion in coke ironmaking. In 1767, the Company began to produce the first cast-iron
rails for
railways. In 1778,
Abraham Darby III producing
Coalport porcelain. In 1802, the Coalbrookdale Company built a rail locomotive for
Richard Trevethick, but little is known about it, including whether or not it actually ran. The death of a company workman in an accident involving the engine is said to have caused the company to not proceed to running it on their existing railway. To date, the only known information about it comes from a drawing preserved at the
Science Museum, London, together with a letter written by Trevithick to his friend
Davies Giddy. The design incorporated a single horizontal
cylinder enclosed in a return-flue
boiler. A
flywheel drove the wheels on one side through
spur gears, and the
axles were mounted directly on the boiler, with no frame. The drawing indicates that the locomotive ran on a
plateway with a
track gauge of . This was two years before Trevethick's first engine to tow a train was run at Penydarren in south Wales. It is here (for example) that the gates of London's
Hyde Park were built. Other examples include the Coalbrookdale
verandah at
St John's in
Monmouth, Wales, and as far away as the
Peacock Fountain in
Christchurch, New Zealand. The blast furnaces were closed down, perhaps as early as the 1820s, but the foundries remained in use. The Coalbrookdale Company became part of an alliance of ironfounding companies called Light Castings Limited. This was absorbed by Allied Ironfounders Limited in 1929. This was in turn taken over by Glynwed which has since become
Aga Foodservice. The Coalbrookdale foundry closed in November 2017. Several of Coalbrookdale's industrial heritage sites are to be found on the local trail: including:
Coalbrookdale railway station, the Quaker Burial Ground, the Darby Houses, Tea Kettle Row and the
Great Western Railway Viaduct. ==Museum==
