Digital Archive: Photographs of Pontynys Mill, Longtown

Place name:





These photographs of Pontynys Mill, Longtown, were taken during the National Mills Weekend open day in May 2010, for which we are grateful to John Hedges, the owner. There is currently no water to the mill, but much of the original machinery is still in place. The design of the mill workings is unusual, with three pairs of millstones and a vertical shaft being driven off a single horizontal shaft connected directly to the right hand side of the pitwheel, and a further single pair of stones and a smutter being driven via another horizontal shaft and gears to the left side of the pitwheel. Diagrams below illustrate the layout, which is made practical by the substantial size of the waterwheel and presumably a correspondingly generous supply of water. This provided enough power for four pairs of millstones and all the ancillary equipment in the mill, rather than the two pairs of stones normally found in a more conventional wallower/ spur wheel arrangement on a vertical shaft.
