SHARPLES CREAM SEPARATORS AND TUBULAR SUPERIORITY. Centrifugal Force varies directly as the diam eter. Centrifugal Force varies as the square of the revolutions. A 4 in. diameter bowl will need three times the revolutions of a 12 in. diameter bowl to give the same circumferential speed. The increase of three times as many revolu tions would give 3X3 9 times the centrifu gal force if the bowls were of the same diam eter. But the higher revolution bowl is but % the diameter of the larger, so the smaller diam eter bowl will have but j/J of 9 times or 3 times the centrifugal force. Thus a bowl 4 in. diam eter running at the same circumferential 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 globules that otherwise cannot be separated. Some manufacturers use complicated inter nal devices to increase capacity, we accomplish a better result by the simple scientific method of reducing diameter and increasing revolu tions. . 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 unequal ed in smoothness and value, because it goes di rectly through an unobstructed bowl, thus obviating any tendency break the globules. The Sharpies Tubular is a clean, rapid, superb skimmer of large res erve capacity and they are sold abso lutely on their merits and subject to a rigid guarantee as to results.
