SHARPIES 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 3X3 = 9 times the centrifu
gal force if the bowls were of the same diam
eter. But the higher revolution bowl is but >3
the diameter of the larger, so the smaller diam
eter bowl will have but yi 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 diameter.
Three men will lift a stone which one man |j I j
cannot budge. Three times the centrifugal 11; i
force will recover small cream globules that 1• j
otherwise cannot be separated. j '
Some manufacturers use complicated inter- 11 ’ I
nal devices to increase capacity, we accomplish | |
a better result by the simple scientific method |< i ,
of reducing diameter and increasing revolu- Jll H
tions. In this way, we preserve simplicity and
durability, make a bowl weighing thirty pounds l]||| j
do more work than any other bowl of three
times the weight, and produce a cream unequal
ed in smoothness and value, because it goes di- gi
rectly through an unobstructed
bowl, thus obviating any tendency W
break the globules.
The Sharpies Tubular is a clean,
rapid, superb skimmer of large res- \ 'id
erve capacity and they are sold abso- h| L . .
lutely on their merits and subject to W® ““
a rigid guarantee as to results.
