"
This invention has for its object improvements in thrashing machines and relates
especially to the "smutter "the final dresser and parts connected therewith. The
general arrangement is that the dressing riddles (of extra large size) are placed
immediately below the smutter, in the middle of the machine. The grain raised
by the elevator, is delivered by an incline into the wire gauze cylinder of the
sinutter, it is carried on by the blades and rubbers on the rapidly revolving axis
within the smutter, and it is delivered at the end of the cylinder. The grain falls
from the smutter into a hopper attached to the side of the dresser which leads it
back to the riddle. The first peculiarity in our arrangement is in the incline
leading from the elevator into the smutter, it contains a slider or drawer which
when drawn allows the grain to pass direct to the dressing riddles by means of a
hopper on the other side of the dresser corresponding to that into which the corn is
delivered after passing through the smutter, thus rendering the riddles available
without the corn having to pass through the smutter and without the aid of a
worm or creeper.
Another peculiarity is that an exhaust fan is provided upon the axis of the
smutter at its further end; this fan draws air through the smutter and delivers it,
with the dust which it carries away through a grating at the periphery or by
means of a spout leading to the ground from its periphery. The fan can be made so
as to be disconnected from the smutter axis and thus rendered inactive without
being removed when not required, or its power of drawing from the smutter can be

page_text: regulated by a door on the outside of the machine by which more or less air can be
admitted, thus reducing the force of the current from the smutter. Another
peculiarity consists in the interposition of an inclined cover plate between the
smutter and the dressing riddles; the dirt and seeds falling through the smutter
are received upon this cover plate and pass off and away by a suitable conductor
thus making a complete separation or dressing by means of the smutter before
going into the final dresser. The grain whether it comes direct from the elevator
or from the smutter comes in beneath this cover plate, on one side or the other, it
is received on to an inclined board with distributing ridges upon it. The grain
falls from this machine board on to a second board inclined the opposite way and
from this it falls on to the upper riddle in a stream which is spread evenly across
the entire width of the riddle. The grain in descending from the upper to the lower
riddle meets a blast of air supplied in the usual manner.

This Invention has for its object improvements in thrashing machines and relates
especially to the "smutter" the final dresser and parts connected therewith. The
general arrangement is that the dressing riddles (of extra large size) are placed
immediately below the smutter, in the middle of the machine. The grain raised by
the elevator is delivered by an incline into the wire gauze cylinder of the smutter,
it is carried on by the blades and rubbers on the rapidly revolving axis within the
smutter, and it is delivered at the end of the cylinder. The grain falls from the
smutter into a hopper attached to the side of the dresser which leads it back to the
riddle. The first peculiarity in our arrangement is in the incline leading from the
elevator into the sinutter, it contains a slider or drawer which when drawn allows
the grain to pass direct to the dressing riddles by means of a hopper on the other
side of the dresser corresponding to that into which the corn is delivered after
passing through the smutter, thus rendering the riddles available without the corn
having to pass through the smutter, and without the aid of a worm or creeper.
Another peculiarity is that an exhaust fan is provided upon the axis of the
smutter at its further end; this fan draws air through the smutter and delivers it
with the dust which it carries away through a grating at the periphery or by
means of a spout leading to the ground from its periphery. The fan can be made
so as to be disconnected from the smutter axis and thus rendered inactive, without
being removed, when not required or its power of drawing from the smutter can
be regulated by a door on the outside of the machine by which more or less air can
be admitted, thus reducing the force of the current from the smutter.
Another peculiarity consists in the interposition of an inclined cover plate
between the smutter and the dressing riddles, the dirt and seeds falling through
the smutter are received upon this cover plate and pass off and away by a suitable
conductor thus making a complete separation or dressing by means of the smutter
before going into the final dresser. The grain whether it comes direct from the
elevator or from the smutter comes in beneath this cover plate, on one side or the
other, it is received on to an inclined board with distributing ridges upon it. The
grain falls from this inclined board on to a second board inclined the opposite way
and from this it falls onto the upper riddle in a stream which is spread evenly
across the entire width of the riddle. The grain in descending from the upper to
the lower riddle meets a blast of air supplied in the usual manner.
In order that the Invention may be fully understood and readily carried into
effect we will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS
Figure 1 shews a transverse section and Figure 2 a longitudinal section of so
much of a thrashing machine as is required to illustrate our Invention.
A is the smutter which consists of a cylinder of wire gauze fixed to the frame
of the machine.. B is an axis carrying blades and rubbers which revolves rapidly
in the smutter A C is a shoot fixed on the smutter it delivers the grain into a
hopper D on the jigging frame which carries the riddles.
E is the elevator for raising the grain. From thence it falls onto the incline F
and so to the smutter but if the incline F be drawn back the grain passes by the

page_text: shoot c and hopper d direct to the riddles without passing through the smutter.
G is a fan on the axis B it is shewn separately in section in Figure 3. This fan
draws air through the smutter and delivers it, with the dust which it carries away
through a grating at the periphery or by means of a spout leading to the ground
from its periphery. The fan can be made so as to be disconnected from the
smutter axis and thus, rendered inactive, without being removed, when not
required, or its power of drawing from the smutter can be regulated by a door on
the outside of the machine by which more or less air can be admitted thus reducing
the force of the current from the smutter.
H is the inclined cover plate between the sinutter and the dressing riddles. The
dirt from the smutter falls on to it and passes off into the trough h. The grain
whether it comes from the hopper D or the hopper d comes in underneath the
cover H on to the inclined board J which is provided with distributing ridges j
(Figure 4). The grain falls from the board J on to the board J' which is inclined
in the opposite direction from, this it falls onto the upper riddle K in a stream
which is spread evenly across the entire width of the riddle K'. L Figure 2 is a
fan for causing a blast of air to pass between the upper and lower riddles K and K'
as is usual. The grain from the riddles passes out through the shoot M.
Having thus described the nature of our said Invention and the manner of
performing the same we would have it understood that what we claim is.
First. The arrangement of the smutter and riddles of a thrashing machine
whereby the grain may either be caused to pass through the smutter and from
thence to the riddles or else be led direct to the riddles, substantially as described.
Second. Providing an exhaust fan at the further end of the axis of the smutter.
substantially as described.
Third. The cover plate H interposed between the smutter and the riddles
substantially as described.,
Fourth. The general arrangement of apparatus substantially as described.

In witness whereof I the said Arthur Samuel Francis Robinson have hereunto
set my hand and seal this Twenty second day of November in the year of
our Lord One thousand eight hundred and eighty two.
