Sharpies Cream Separators AND TUBULAR SUPERIORITY. Centrifugal rorce varies directly as the diameter. Centrifugal Porce varies as the square of the revolutions. A 4 in. diameter bowl will need three times the revolu tions of a 12 in. diameter bowl to give the same circum ferential 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 X the diameter of the larger, so the smaller diameter bowl will have but X of 9 times or 3 times the centrifugal force. Thus a bowl 4 in, diameter run ning at the same circumferential speed will have three times the centrifugal fot ce of a bowl 12 inches iu 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 internal devices to increase capacity; we accomplish a better result by the simple scientific method of reducing diameter and in creasing 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 an unobstructed bowl, thus obviating any tendency to break the globules.
