SHARPLES 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 Y 3 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 dian►peter.
L'hree men will lift a stone which one man
cannot budge. Three times tl•►e centrifugal
force will recover small cream globules that
otherwise cannot be separated.
Some manufacturers use complicated inter
nal devices to increase capacity, we accomplish
a better result by the simple scientific method
of reducing diameter and increasing revolu
tions..' In this way, we preserve simplicity and
durability, make a bowl weighing thirty pounds
do more work than any other bowl of three , i,;
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 tendency
break the globules. '
