long service it must contain the high
est quality of material and workman
ship and be designed to accomplish a
thorough separation of cream and skim
milk without tearing itself to pieces.
Spiral cut gears are now used i'm the
best separators because they run
smoothly and prevent Earring. loose or
unsteady motion, or back-lash. They
do this because they have four teeth
in mesh where spur cut gears have
one tooth in mesh at time. The
slightest Earring or unsteady motion
in theg ears will be transmitted to the
bowl and will cause it to vibrate and
do poor work. Hence, the value of
smooth-running spiral gears can easily
be appreciated.
The quality Of material used in
making the gears will materially affect
the amount of wear they will stand.
Tough, c!ose-grained iron Is the best
material for this purpose as it wears
smoothly and does not grind or cut.
The shafts, spindles, and frame of
separator are among the most expen-
be protected from wear as much as
possible. In the better grade of cream
separators, phosphor bronze bushings
are used TO protect the frame and
operating mechanism. This is very
smooth, tine-grained metal which does
not cut the parts moving In it. 1t is
slightly softer than the steel shafts
xVh IN nd
consequently bears the burden of wear
Herein lies its value as the bushings
can be replaced at very small cost
whereas it would be considerable
expense to replace the shafts, spindles,
and frame.
The bowl spindle or neck bearing of
a separator is one of the features a
farmer should carefully investigate.
The purpose of this bearing is to keep
the bowl properly centered and to pre-
vent shocks or vibrations from being
transmitted to the bowl from the
gears. This bearing to be satisfactory
must be strong, simple, and free from
the necessity of difficult adjustments.
The fewer parts the bearing has the
better, providing, the parts are prop
erly made.
Every farmer naturally wants a sep.
arator that Is easy to turn. BY all
mean separator should be easy to
operate, and many Of them are, but
unfortunately for the purchaser this
quality is often secured by building
the machine light - by sacrificing
durability. 1t is poor business sense
to buy light, fiimsily constructed
separator simply because it is easy to
turn. Such aseparatOr will not stand
lup under the work for long enough
period to be a profitable investment
Milk as 1t comes from the COW is one
of the purest articles of food, but it Is
also very easily contaminated. There
fore the separator bowl must be kept
in clean, sanitary condition. Don't
Judge the easy-cleaning qualities OF
a separator by the number of pieces
the bowl contains. What Is infinitely
more important Is the construction of
the parts. A plain, smooth surface Is
easily cleaned, whereas, intricate crew.
ices and corners are hard to get at and
will often be Improperly cleaned.
In selecting separator do not be
misled by the price. Those who try
to sell a machine and use as thei.
strongest argument its low price, often
use this argument because they have
mo other. The man who is selling low
priced machines is making just a.
much profit as the man who sells
high grade machine at slightly higher
price. TKs difference is in the quality
Of the machine.
