SHARPLES CREAM SEPARATORS AND TUBULAR SUPERIORITY. Centrifugal Force varies directly as the dia 111- 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 yj the diameter of the larger, so the smaller diam eter bowl will have but A 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- f|| lutely on their merits and subject to a rigid guarantee as to results.
