their proper speed. Such . belt also
tends to run OF the pulleys and wear
out the belt and the pulley facings.
On the other hand. a belt should not
be too tight.
Whenever the tagging comes OF a
pulley. 1t should be replaced imme-
diately. Covered iron pulleys have
considerably more adhesion than un-
covered ones of the same size with the
same belt tension. The important
thing in covering a pulley is to get the
leather or other tagging as tight as
possible. Otherwise is will soon pull
of again. Obviously, the nails or riv-
cts should not be left projecting above
the surface to injure the belt.
Running Leather Belts.
All leather belts should be run with
the grain or hair side next to the pull
ley. The outside OF belt must stretch
a little every time il goes over a pull
ley, and, as the flesh side is more elias
tic than the hair side. the belt will
last longer If run in this manner. Also
the grain side Is smoother and will
transmit more power because IL brings
more surface into actual contact with
the face Of the pulley. A leather belt
which has become dry and hard can
be made soft and pIiable again by
cleaning it thoroughly and applying
neat's-foot oil, castor oil. or some other
reliable belt dressing.
ROsin or mixtures containing enough
rosin to leave the surface of the belt
in a sticky condition should not be
used to keep belt from slipping. They
will make the belt more adhesive for
a short time, but 1t will soon become
glazed and slip more than before the
rOsin was applied. Lubricating OIL Is
Injurious to all kinds of betting. which
should be kept as nearly free as pos
sfble from this substance. A leather
belt that has become saturated with
oil can be restored in large measure by
scraping 1t AZ clean as possible and
packing ii I'm dry sawdust for three or
four days. SpOnging the belt with gas
Oline. or even dipping II. will remove
the oil quickly. Too much gasoline.
however, may take all the dressing out
of the belt, and If II seems too dry
after the gasoline has evaporated,
more dressing should be applied. Oil
can be washed off rubber belt with
soap and water without injury to the
belt
The lacing of a belt should be such
that 1T will pass over the pulleys with
little or no shock or jar. A lacing
should be fastened otherwise than by
tying knot, especially If the belt runs
over an idIer or tightener
Service OF Separator.
The total amount of service which
separator will give depends more than
anything else upon the care and oiling
Of the bearings. This is especially true
Of steel sepAratOrs. Before the ma
chine is started on the seasons work.
it is imperative that 1t be gone over
carefully to see that all journals and
boxes are in proper shape and plenti-
fully supplied with Oil. Since the sep
arator has Sd many parts which move
at a high rate of speed, and the whole
machine is subject to constant strain
and vibration while In motion. any
parts that are not perfectly solid and
fight are almost sure to give trouble
before the season Is over. The failure
Of any one part will stop not only the
machine. but the entire tbrashing crew
as well.
A good grade of Oil should always be
used. Oil OF inferior grade will cause
more wear on the bearings and may
necessitate more frequent stopping.
Lengthening the working life of q ma.
chine as expensive rs a separator by
even a few days. or the saving Of only
a few lopurs' time by the crew. will
more than pay the difference between
the cost Of inferior and high-grade
lubricating oil. A good grade Of light
oil will cover the bearings which II IL
intended to Intricate more thoroughly
and quickly than will thick. heavy OIL.
In hot weather thicker and heavier
oil can be used more satisfactorily than
is possible i'm cold weather. A bearing
il more likely to be continually lubri.
Gated when a small amount of oil lie
applied frequently than when a large
quantity is applied at rare intervals.
II Oil is applied to q bearing while the |
machine is in motion 1t will be quickly
and evenly distributed over the bear.
