SHARPLES 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 th the revolutions of a 12 in. diameter bo the same circumferential speed. The increase of three times as mai; 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 A of 9 times o the centrifugal force. Thus a bowl 4 eter running at the same circumferen' will have three times the centrifugal 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 complical nal devices to increase capacity, we a< a better result by the simple scientific of reducing diameter and increasm, 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 shimmer of large res erve capacity and they are sold abso lutely on .their merits and subject to a rigid guarantee as to results.
