Is your Cream Separator Turned
at Proper Speed.

| your separator at that speed all the
time, then with your twenty COWS
you've lost 1924. 10 worth of butter in
one year!''
The above is the astounding state
ment made by dairying authority to
farmer whom he had been watch
ing operating his cream separator.
| When you buy cream separator
| you will find on the crank handle, in
large raised letters instructions some
thing like this-''55 revolutions per
minute" Or it may read 45. or so, or
60; it varies on the different makes Of
separators
| Suppose, for example, that yours
reads SO revolutions per minute. =
What does that mean? 1t means
that whenever you operate that
cream separator you should turn the
crank handle precisely So turns to
the minute.
The manufacturer has tested his
separator under every possible condi-
tion in order to know the exact
method Of operation at which it
gives the highest degree of efficiency.
But how does the dairyman KNOW
how many times he turns it? 1t is
just as impossible to guess accurately
the speed Of his cream separator as
it is to guess accurately at other
things.
At a first-class dairy farm the sup
erintendent said he always ''guessed9
the proper speed. When asked how
his helpers operated the separator
he replied that, after he had broken
new men in, they could also operate
it at approximately correct speed. In
order to prove his statement, one of
his helpers was asked to turn the
separator at the speed he usually OPP
Grated it. The number on the crank
handle read "48 revolutions per min
Ute" But the helper made only IS
TURNS to the minute.
This proved how absolutely wrong
the superintendent was in supposing
that he, or any of his helpers, could
tell when they were turning the
crank handle exactly right. OR ANY
WHERE NEAR, what the manufactur-
er told them it should be turned.
Here were pounds Of butter-fat going
to the hogs daily, just because he
guessed" and if he will feed
calves and hogs with butter-fat
worth 30 cents pound, when he can
feed them BETTER on two and one
half pounds Of corn meal and skim
milk, then that shows how much the
dairymen have to learn to get all the
profits out of dairying and farming.
At the Perdue Experiment Station
Indiana, very exhaustive tests were
carried on to show the tremendous
losses through wrong operation of
cream separators. A separator was
run at it's normal speed of 80 turns to
the crank handle per minute. Fifty
pounds of milk were run through the
separator. At this speed, it deliver
ed As pounds of skim milk and 5
bounds of cream. This cream tested
2.1l pounds OF butter-fat. When the
speed was increased to Is turns q
minute, the skim milk discharged
was 463 pounds, reducing the cream
TO 81 pounds And the amount o.
butter-fat was slightly less than when
che separator was turned at norma
speed.
Next, q test was made by letting
the speed OF the machine drop uown
10 vhat at which it mas been found
til6 average daifynnail operates g
cream separator, with the astonish-
ing result that the discharge from
cream spout went up TO 81 pounds
but it tested only IL per cent Of but
teri at-only 1.04 pounds OF fat out
of 80 pounds Of milk, as against I'll
pounds when the separator was OPP
Grated correctly.
Dairymen are. losing from 20 to 5U
per cent Of their butter-fab with ev-
cry operation. This is a matter OF
waste that is simply appalling when
the aggregate hgures OF all the dairy
men in this country are considered
1t probably runs into thousands o.
dollars WITH EACH DAILY MILKING.
Now speed indicator has been IL
vented to be applied TO cream sepa-
rafors. mounted on the crank shaft
OF The separator. AS the separator
handle is turned, the exact number
Of revolutions per minute that the
crank handle is making is shown III q
definite figure, so that 1T may De
read at a glance. There is no calcu-
lating to be done; it is only necess-
ary to keep on turning tue iiandle ui.-
