with all the dirt and hair on it and
the -four made into bread and eaten
by our forefathers. The crude crushing
of wheat was once considered the
making of -four. How different the
process now. A kernel of wheat has
to be treated to a shave, brushing and
a bath before it is considered proper
to introduce to the rolls. We will
follow it on it's journey from the ele-
vator to the sack. In an adjoining
elevator are two receiving separators.
Their work being to take out all the
foreign particles they possibly can.
After passing through these twice the
wheat is then introduced into the mill
by the means of an iron spout
and again passes through another
series of receiving separators, their
work being practically the same as the
ones in the elevator but more perfect
ed. After all the foul grain and seeds
have been removed it then goes to the
securing machines, which are the
most interesting pieces of machinery
in connection with modern milling.
These are the wheat BARRIERS. They
consist of corrugated and perforated
cylinders of chilled steel. inside of
which, and running at speed of 800
revolutions to the minute are what are
termed "beaters, resembling the
paddles on the propelling wheels of
steamboats, these heaters run just
close enough to the cylinder to scrape
and shave the wheat as it passes be-
tween, without breaking the she'll.
At the ends of these cylinders are fans
which run so as to create powerful
suction around these perforated cylin-
ders 80 that as the hair and dirt are
shaved off the wheat and fall through
the perforations it is drawn by a
powerful current of air into shallow
chamber, from which is depended a
large gang of cloth tubes, each three
inches in diameter, which look as
much like huge candle moulds as any
thing. A carriage of crossed wires
travels up and down this set of tubes,
slightly depressing them. The little
tempest of dust which seeking an out
let is brought from the securing ma
chimes; and dives down into these
cloth tubes, the air escaping through
the meshes of the cloth, which by the
J way is made especially for this pur-
pose, and the dirt drops into a spout
and is conveyed to the basement for
final destruction. Thus is ingeniously
solved the question which for many
years was the bane of the milling
business, viz: the dust question. The
wheat now being thoroughly cleaned
passes through two upright fue bill
ers, where it is heated by steam. The
heating is done to remove brittleness
and to prepare the. wheat for gradual
reduction, as experience proves thai
wheat breaks up more evenly when
heated and takes to the rolls more
kindly than when in its natural state
The wheat is now carried to -four
sets of 9x1S corrugated rolls for it,
first breaking, and from thence to two
primary "scalpers, where the 'mid
dlings" or interior part of the berry
is removed from the shell, or outsid,
part of the kernel. The former i
} thence passed to reels and separated
into four sizes, each in turn passing
through purifiers, where by the al
system previously described, the dus
that may have accumulated on it
Journey is removed. Then they rol
J on over and through sixteen. sets O
