THE
COMPLETE
PRACTICAL
DISTILLER.
EEDUCTION
OF
POTATOES.
When
the
potatoes
have
been
boiled
suitably,
they
occupy
a
greater
space,
and
this
dilatation
causes
their
peel,
which
is
not
very
strong,
to
be
broken
;
this
ren-
ders
them
proper
to
be
submitted
to
the
action
of
the
reducing
machine,
of
which
a
description
will
now
be
given.
This
machine
is
represented
by
figs.
17
and
18.
Fig.
17
is
a
lateral
elevation
of
it,
showing
the
side
of
the
machine
where
the
two
wheels
work
in
each
other.
Fig.
18
is
a
plan
of the
machine,
as
seen
from
above,
without
the
hopper.
The
same
letters
represent
the
same
pieces
in
both
figures.
A
A A
A
is
a strong
frame
built in
oak.
B
and
c
are
two
cylinders
made
of
wood
or
of
stone,
but
better
of
cast-metal.
These
two
cylinders
are
of
equal
diameters;
they
are
a
short
distance
from
each
other,
and
their
function
is
to
break
the
potatoes
by
their
unequal
rotatory
motion.
This
unequal
rotation
is
ob-
tained
by
means
of
two
wheels
of
difl*erent
diameters,
a
and
6.
D
is
a
movable
hopper,
supported
by
the
frame
in
c
d.
It
is
made
for
the
purpose
of
receiving
the
potatoes
to
submit
them
to
the
action
of
the
cylinders.
E,
F
are
two
handles
fixed
on
the
axis
of
the
cylinder
0.
They
serve
to
work
the
machine.
G
H
is
a
scraper.
It
hangs
on
e,
and
the
weight
g^
which
acts
upon
the
lever
G

presses
the
extremity

of
the
scraper
against
the
cylinder
B.
