SIIARFUS CREAM SEPARATORS AND TUBULAR SUPERIORITY. Centrifugal Force varies directly as the diameter. Centrifugal Force varies as the square of the revolutions. A 4 inch diameter bowl will need three times the revolutions of a 12 inch diameter bowl to give the same circumferential speed. The increase of three times as many revolutions would give 3 X 3 = 9 times the centrifugal force if the bowls were of the same diameter. But the higher revolution bowl is but 1 / 3 the diameter of the larger, so the smaller diameter bowl will have but of 9 times or 3 times the centrifugal. force. Thus a bowl 4 inch diameter running at the same circum ferential speed will have three times the centrifugal force of a bowl 12 inches in diameter. Three men will lift a stone which one man cannot budge. Three times the centrifugal force will recover small cream glob ules that otherwise cannot be separated. Some manufacturers use complicated internal devices to in crease capacity, we accomplish a better result by the simple sci entific method of reducing diameter and increasing revolutions. In this way, we preserve simplicity and durability, make a bowl weighing thirty pounds do more work than any other bowl of three times the weight, and produce a cream unequaled in smoothness and value, because it goes directly' through au un obstructed bowl, thus obviating any tendency to break the globules. . . 7.'lo..slzarples Tubular :is .a clean, rapid, ,superb sOnmer of large reserve . capacity and they are sold absolutely on 4hefr merits and subject to a rigid guarantee as to results.
