SIIARPLES 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 to give the same circumferential speed. The increase of three times- as , many' revolu tions would give 3 X 3 = 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 % of 9 times or 3 times the centrifugal force. Thus aloowl4 'in. kdiam 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 complica 4 naLdevices to increase. capacity, we, aA a better result by the simple scientific of 'reducing 'diameter and • increasing tions. In this way, we preserve situp] durability, make'a bowl weighing thin do more work than any other bowl times the weight, and produce a cream ed in smoothness and value, because it 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.
