Excerpt from Mining and Ore-Dressing Machinery: A Comprehensive Treatise Dealing With the Modern Practice of Winning Both Metalliferous and Non-Metalliferous Minerals Were we to divide the radius 30 ft. Into six equal parts, and calculate the angles at each point, we should find them correspond nearly with the means of those given by Smeaton and others. Mills are generally made with four strong wooden arms or radii, fixed firmly in a central socket, and steadied and stiffened by tie-rods, connecting their extremities together, and with a projecting strut on the central boss. The width of each sail at the extreme should be about half of the radius, so that in a mill 60 ft. Diameter, or 30 ft. Radius, each sail would be 15 ft. Wide at the extreme. The part of the arm next the centre for about 71; of the radius, that is, 5 ft. In the case supposed, is not fitted with sails because the surface there is so little effective, as well from its short leverage as from its obstructing the wind reflected from the head of the turret behind it. The width at the inner end should be of the radius, or 10 ft. The surface of each sail is therefore 312 sq. Ft., and the total of the four is 312 X 4 1250 sq. Ft. The total area of the circle 60 ft. In diameter is somewhat above 2800 sq. Ft., so that not half the surface of the circle is clothed with sails. There would be no disadvantage in extending the surface by making the sails broader or more numerous, until it became of the whole surface. Beyond this additional sail-surface is disadvantageous, for it appears to obstruct the free passage of the currents re ected from the sails, and thus clogs their motions. It is found advantageous to arrange the surface of the sail somewhat in the proportions of Fig. 2, which represents the front View of one sail.
