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 in the
best separators because they run
smoothly and prevent jarring, 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 jarring 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, clOse-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-
siYe parts Of the machine and should
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 a very
smooth, tine-grained metal which does
not cut the parts moving in it. 1t is
slightly softer than the steel shafts
and spindles which move in it, and
consequently bears the burden of wear.
Herein lies its value as the bushingS
can be replaced at very small cost
whereas il would be a 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 a 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 a light, fiimsily constructed
separator simply because it is easy to
turn. Such aseparatOr will not stand
up under the work for a long enough |
period to be profitable investment. |
Milk as it 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 a 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 a separator do not be
misled by the price. Those who try |
to sell a machine and use as their
argument its low price, often
use this argument because they have
no other. The man who is selling low
priced machines is making just as
much profit as the man who sells a
high grade machine at slightly higher
price. The difference is in the quality
Of the machine.
