ficult in sharpening. The band cutters
should be placed not at the end of tho
carrier but toward the front at leasttwo
feet. When placed in this position the
teeth in the carrier hold the bundles
back while the knives cut the bands.
If they are placed at the end of the car
rier there is nothing to hold the bundles
back and when the knives get dull they
will throw a bundle clear into the cylin-
der and that means loose teeth and
wasted grain, besides racking the mach
inc and taking twice the power. A Self
Feeder should be equipped with a COVER
nor and of the two kinds, friction and
engine, I think that the friction is the
best for on a self feeder it is almost i'm
possible to protect a governor from the
dust which soon fills the working parts
of an engine governor so full that it will
not work at all while a friction governor
is not bothered this way. A feeder
should always be supplied with a straw
governor arranged SO that when the
machine got to full of straw the motion
of the feeded would slow down until it
cleared out. Back of the band cutter
cylinder there should be placed a set Of
forks to spread the grain the full width
of the cylinder and to feed the grain to
it from tho top while the teeth in the
carrier holds the bottom part back.
We now come to the cylinder which is
the most important part Of the machine.
A cylinder should be about 36 inches in
diameter and should contain Is or 20
double bars with about twelve teeth to
the bar in a Sc inch machine. Itshould
weigh 900 or a thousand pounds and
should be mounted on a two and a half
or three inch shaft running in long self
adjusting boxes. The teeth should be
large and strong with a long tapering
shank which should pass through the
double bars and be held in place by a
large nut and spring washer. They
should be strong enough to thresh all
kinds of tough grain and even a pitch
fork once in a while without being dam.
aged very badly. The advantages OF
this large cylinder are that it acts as a
balance wheel thus giving the machine
a more even and steady motion, three
times the CRATE surface right where
most Of the separation is done, makes it
possible to use pulleys twice as large,
thereby preventing slippage of the belt
and allowing the cylinder to run slower
while the teeth go through the grain
just as fast as in the old style. This
slow motion makes a much longer lived
machine and also gives less chance for
hot boxes etc. Right behind the cylin.
der a beaten should be placed in such d
position that it will stop the straw as it
is thrown from the cylinder and urn it
down onto the straw racks.
The straw racks should be in three or
four sections arranged so that when the
first section is going forward fhe second
will be coming back and there should
be a drop Of at least 10 inches at the end
of each rack. Each rack should be
driven at lis forward end by a shaft
crooked enough to allow a throw of al
least eight inches AMI supported at its
back end by good heavy wrought iron
or steel hangers. When the IA ks are
arranged in this way it causes a break
in the straw every time it passes from
one rack to another and there is fal
more separation done where there is q
break than where the straw passes along
90 top OF a solid rack. The straw il
also constantly changing its position OF
tho racks owing to their difference it
motion and by the time the straw
reaches the end of the last rack tht
grain is pretty well shaken out. Some
AZ operators are built with a double sep
a~rating table one above the other. Tn.
upper one is made very open 80 that al
The short straw and chat drops through
onto the second table where the grain is
more easily shaken out. This devise
also allows the machine to be bull
shorter aud more compact. The stray
racks SHOULD be made of good timber
le'd together with bolts and screws.
The grain pan should be made in two
sectious. The first should be OF sheei
steel made in steps so as to move the
grain toward the rear and the back hall
should be open to let the grain through
OTTO the shoe. They should counter
balance each other like the straw racks
