Cyfartha lead mine - wheel pit
Cyfartha lead mine - wheel pit
This structure once housed a water wheel, driven by water taken from the Nant Ddu (and supplemented by a leat carrying water from the Nant Goch). The power generated here would have been transmitted mechanically to the engine house LinkExternal link next to the shaft LinkExternal link of the mine a short stretch upstream of the Nant Ddu. The function of the structure attached to the side of the wheel pit LinkExternal link is not entirely clear to me at present. It would seem reasonable that the crank driving the flatrod system to transmit power to the engine house would have been housed in it, but I cannot see an opening for the mechanism to emerge from. The wheel pit is listed on the Coflein[1] database LinkExternal link .

Cyfartha mine is also known as Nantddu mine since most of its buildings are located in the valley of the Nant Ddu. Mine operations at Cyfartha lasted from 1842 to 1881. The ore was mined mostly for its lead and copper content. Cyfartha was an underground mine, with access to the levels through a number of shafts. Power was generated using two water wheels and a horse-powered whim. The water feeding the wheels came mainly from the Nant Ddu, supplemented by a long leat abstracting water from the Nant Goch about a kilometre to the north. Since the water wheels are located lower than the openings of the engine shafts, power was transmitted using a flatrod system, i.e. a series of linked iron rods moving backwards and forwards as the wheel turns (see Wikipedia article on Eylesbarrow mine in Devon LinkExternal link for details of the mechanism). For a detailed description of the mine, see Clwyd-Powys Archaeological Trust LinkExternal link . Cyfartha mine as whole is listed in the Coflein[1] database LinkExternal link .
