SRARPLES CREAM SEPARATORS AND TUBULAR SUPERIORITY. Centrifugal Force varies directly as eter. Centrifugal Force varies as the squa, revolutions. A 4 in. diameter bowl will need thi the revolutions of a 12 in. diameter bo\ the same circumferential speed. The increase of three times as man tions would give 3X3 = 9 times the gal force if the bowls were of the sa eter. But the higher revolution bowl the diameter of the larger, so the sma! eter bowl will have but of 9 times o the centrifugal force. Thus a bowl 4 eter running at the same circumferent will have three times the centrifugal i bowl 12 inches in diameter. Three men will lift a stone which cannot budge. Three times the ce force will recover small cream glob otherwise cannot be separated. Some manufacturers use complicat nal devices to increase capacity, we at a better result by the simple scientifii of reducing diameter and increasin, tions. In this way, we preserve simp durability, make a bowl weighing thir do more work than any other bowl times the weight, and produce a cream ed in smoothness and value, because i 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.
