Figure 30. A Champion geared wind mill. A vane is placed at an offset to the center line of the shaft in this model to offset the tendency of the wheel to go with the strain of the gear. This is not necessary in pumping mills, with the crank motion, as the strain is then entirely vertical. In: "The Wind Mill As A Prime Mover," by Alfred R. Wolff, p. 107. 1885. Library Call No. M/1380 W855.
