William Fairbairn described 'an ingenious contrivance' for dynamically balancing millstones made from blocks of French burr, incorrectly naming the firm as 'Clarke & Durham' [1]. Weights were installed at 90 degree intervals in vertical holes in the wheels. The height of each stack of weights was adjustable by a screw, and by this means the wheel could be made to rotate in balance and without wobble. The holes were covered by plates showing the patent date 1859.
