SIfARPLES 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 1;o give the same circumferential speed. The increase of three times as many revolu- | lions 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 '/s 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. j Some manufacturers use complicated inter- j nal devices to increase capacity, we accomplish | a better result by the simple scientific method | of reducing diameter and increasing revolu- J tions. In this way, we preserve simplicity and || durability, make a bowl weighing thirty pounds II 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 tendenc3' break the globules. • sftjjjmh.
