“The large wheel a, is supposed to stand over the well, and b, a smaller wheel, is fixed in the water. The rope is extended between the two wheels, and rises on one side in a perpendicular disrection. On turning the wheel by the crank d, the water is brought up by the friction of the rope.” -Comstock 1850
