Parkandillick Gallery 2, the images on this page are of the Boiler House also the Clay Winder House. It has to be said it was an amazing time spent there.
But I must arrange to go back sometime to get more images of the outside. Sadly the film with the most exterior images did not develop correctly.
These remaining images were taken in the “Winding House” which is joined via a small doorway. This room contains the small twin cylinder winding engine.
This hauled rail-mounted skips up two inclines to form the conical waste ‘sky tips’ once typical of the area. This was done by means of two winding drums, individually dog clutched to the drive shaft.
Either drum could hoist a loaded skip, which ran back empty into the pit under gravity, controlled by the drum brake. Also chain driven dials, known as ‘miniatures’, would indicate the skip positions.
The engine and drums were not designed as a unit, the drive being a local adaptation. The engine is a twin simple with cylinders of 12” bore and 14” stroke. It is of the ‘colonial’ type, which splits down into units. So it is suitable for conveyance by pack animals into remote areas.
Exhaust steam was led to a heat exchanger in the Cornish engine’s cataract chamber to preheat the feed water to the boiler, and hence to atmosphere. (Courtesy of The Trevithick Society)
