Model of pit shaft with cages and guides (scale 1:12), from design by G. V. Hall Esq.
This is a model of a pit shaft with cages and guides. The earliest system for removing coal from the pit was in wicker baskets or 'corves' raised up by rope. Soon this became inadequate as the extraction of coal intensified and deeper pit shafts were dug. A much improved system, devised by T. Y. Hall, was installed successfully at Woodside colliery, near Ryton-on-Tyne, in 1835. This combined the use of guides with a cage in which wheeled tubs from the pit face were raised to the surface. The model, to a scale of 1:12, was built in the same year.
