Topcliffe Watermill - Stone floor
Topcliffe Mill is a well preserved, grade II listed, 18th century building sited on the river Mel. The mill contains three sets of stones, a nice collection of bins, a smutter, horse feed machinery and complete meal floor gearing. The mill house was demolished in the mid 1900s.
Tentering - molinological application (provided by Chris Allen)
In a mill context, tentering is changing the distance (gap) between the runner stone and the bed stone. Decreasing the distance results in a finer grain. As the stones go faster there is a natural tendency for the runner to rise and the tentering mechanism can be adjusted to counter this. In many windmills this is done by a governor that automatically compensates for the tendency of the runner to rise. In watermills it is done by hand with mechanisms of varying elegance. In this case, the second order lever at the bottom raises or lowers the footstep bearing that the spindle carrying the stone nut is supported by. The adjustment is by a vertical lead screw on the other side of the frame and in easy reach of the miller.
