WILLIAM BURLEY and JOHN HEMUS MORGAN, both of St. Johns in the
County of Kent, Millwrights and Engineers "IMPROVEMENTS IN MACHINES
FOR SEPARATING CLEANING AND DECORTICATING GRAIN OR SEED."
Our Invention relates to machines of that class usually termed separating, cleaning,
smutting and decortiating machines, and consists in various improvements as
hereinafter specified.
In practising the said Invention I construct a machine as follows-that is to say,
I provide the same with a suitable casing and place centrally within the same a
column or post of hexagonal or other sectional form and constructed of cast iron or
other suitable material. This column is mounted upon a revolving shaft and may
be arranged either vertically, horizontally, or inclined at any angle.
We prefer
however that it should be vertical. The sides of the said, column are made flat
and holes are bored therein to receive the shanks or ends of fish-tailed or other
shaped adjustable blades or vanes made of cast iron or other suitable materials;
each of these blades is formed with a flange that fits upon the side of the column,
and radial slots are formed in the same through which we pass screws. We thus
provide means for adjusting the said blades to any angle on the column and for
securing them when adjusted. The bottom of the vertical shaft is fitted into a
step in the bed plate and the upper end thereof works in a bearing in the top
Irame of the machine.
The said blades revolve within a perforated steel cylinder which is enclosed

page_text: within an outer case. The said cylinder is made of any desired length and diameter
according to the quantity of grain or seed required to be treated in a given time.
Underneath the said cylinder or casing we fix an exhaust fan operated by the said
vertical shaft to draw off the dust and refuse from the fan-case and through an
exhaust chamber at the side of the machine.
The said machine is fed near the bottom at one side and delivers the grain or
seed at the top on the opposite side of the same. Or this arrangement of the feed
and delivery may be reversed.
We provide the said machine with a separator consisting of a series of sieves
for the grain to pass through before it enters the exhaust-chamber so that the dust
or other impurities will be removed from it before entering the chamber containing
the rotating blades. The separator is mounted upon springs, and under the said
separator we arrange a bracket to receive an arm or piece fitted upon an excentric
fixed or formed on the upper end of the said column shaft for giving a vibrating
motion to the said separator. Or we may employ other suitable devices for this
purpose.
We may apply our improved apparatus consisting of the aforesaid series of
rotating adjustable blades or vanes mounted on a column or post, to a machine to be
used solely for separating the corn or grain from other seed or impurities before
admitting the same to the aforesaid cleaning and decorticating machine.
instances we may mount this rotating separating apparatus above or at the side of
the_aforesaid series_of_sieves, or we may, if desired, dispense-with-the-latter.-
In some

by the said William Burley and John Hemus Morgan in the Great Seal
Patent Office on the 19th June 1882.
WILLIAM BURLEY and JOHN HEMUS MORGAN both of St. John's in the
County of Kent, Millwrights and Engineers. "IMPROVEMENTS IN MACHINES
FOR SEPARATING, CLEANING AND DECORTICATING GRAIN OR SEED."
Our Invention relates to machines of that class usually termed separating, cleaning,
smutting, and decorticating machines, and consists in various improvements as
hereinafter specified.
1
In practising the said Invention we construct a machine as follows;--that is to say.
we provide a suitable casing and place centrally within the same a rotating column
or post provided with a series of radially projecting adjustable vanes or blades to
whose action the grain or seed is subjected to remove the beards and portions of
the skin or pellicle therefrom. The said machine is in some cases provided with
an exhaust-chamber and it has a fan or exhauster which draws the dust and refuse.
from this chamber and from the other parts of the machine
The said Invention is illustrated in the accompanying Drawings in which
Figure 1 is a side elevation partly in section of our improved machine.
Figure 2 is a rear elevation also partly in section showing the interior of the:
aforesaid exhaust chamber.
Figure 3 is a horizontal section on the line x x Figure 1.
Figure 4 is a plan or top view of the separator hereinafter described.
Figure 5 is a side elevation shewing our said machine without the exhaust
chamber.
Like letters indicate the same parts throughout the Drawings.
A is the bed or foundation plate; B B are standards or uprights securely fixed.
in the same and supporting the top frame C; a is the casing which is formed of.
an inner and outer cylinder or shell a' a. The inner cylinder a' is formed of thin
steel or other suitable metal and is perforated with very narrow apertures or slots
as shewn in Figure 1 to permit the waste particles removed from the grain to escape
into the annular space between the two cylinders; b is the column which is hexagonal
or of other suitable sectional form and is constructed of cast iron or other suitable.
material. This column b is mounted upon a revolving shaft c. Holes are bored.
therein to receive the shanks or ends of the blades or vanes d. These blades are.
of the shape shewn or of other appropriate shape and are made of cast iron or other
suitable material; each blade is formed with a flange d that fits upon the side of
the column and radial slots are formed in the said flanges through which we pass
bolts or screws e for securing them in such a manner as to permit their angular
adjustment when required. We thus provide for varying the action of the said
blades according to the nature or quality of the grain or seed subjected thereto.'
The bottom of the vertical shaft is fitted into a step f in the bed plate A and the
upper end thereof works in a bearing y in the top frame C of the machine.
The aforesaid cylindrical casing is made of any desired length and diameter
according to the quantity of grain or seed required to be treated in a given time.
Above the said casing we provide the said machine with a separator h consisting
of a series of sieves through which the grain passes before it enters the chamber
containing the rotating blades so that the grain will be freed from dust or other
impurities before entering the said chamber. The said separator is mounted upon
springs i and is provided on its under-side with a socketed bracket or block
the socket of which we fit a block or piece bored to receive a pin which is fixed
or formed on the upper end of the said shaft c excentrically to the same. The said
in

page_text: socket j and the piece are square or otherwise formed so that the said block
cannot turn in the socket and tlie excentric pin turns freely in the hole in the said
block:
We thus provide in a very simple but efficient and convenient manner for giving
a vibrating motion to the said separator, but it is obvious that we may employ
other suitable devices for this purpose if desirable.
Below the said cylindrical casing a we arrange an exhauster or exhaust fan Z
operated by means of the said vertical shaft to draw off the dust and refuse from
the fan case and through the exhaust-chamber m which is arranged at the side of
the machine as shewn in Figure 1. In some instances we dispense with the said
exhaust-chamber and conduct the grain from the separator directly into the
cylindrical casing by a spout o arranged as shewn in Figure 5 the fan being arranged
to draw the refuse from the said casing.
The grain or seed is supplied to the separator by any convenient means; the
greater portion of the dirt or refuse is separated therefrom by the sieves and
is discharged by the spouts 3 ; the grain passes from the spout ³ into the
exhaust-chamber and thence into the casing (or if the machine is constructed as in
Figure 5 directly into the casing). It enters the casing on one side thereof at or
near the bottom of the same and is discharged at the opposite side through the
top of the casing and the spout p. In some instances this arrangement of the feed
and delivery is reversed.
We may apply our_improved apparatus-consisting_of_the_aforesaid-series-of-
rotating adjustable blades or vanes mounted on a column or post, to a machine to
be used solely for separating the corn or grain from other seed or impurities before
In some
admitting the same to the aforesaid cleaning and decorticating machine.
instances we mount this rotating separating apparatus above, or at the side of, the
We have
aforesaid series of sieves, or we may if desired dispense with the latter.
shewn the same machine with its casing and series of vanes arranged vertically but
if desired they may be arranged horizontally or at any desired angle.
Having thus fully described our said Invention and the manner of performing
the same, we wish it understood that although we have shown in the accompanying
Drawing such details of construction and arrangement as we consider will be very
advantageous for the purposes of our Invention yet we do not limit ourselves
strictly to such details, neither do we claim generally the combination of apparatus
for decorticating grain or seed with separating sieves and exhaust apparatus, but
we claim
First. A series of blades or vanes mounted adjustably, or otherwise, upon a shaft
or column within a cylinder or casing substantially as shown and described, and so
arranged and operated that by their rotation they effect the decortication of the
grain or seed in the manner specified.
Second. The combination with the aforesaid separator, of the excentric device
arranged upon, and operated by, the shaft which carries the rotating blades,
substantially as, and for the purpose, specified.
Third. A machine consisting of the parts constructed and arranged as shown in
Figure 1 or in Figure 5 of the accompanying Drawing and operating as and for
the purposes specified.
In witness whereof I the said John Hemus Morgan, for myself and on
behalf of the said William Burley, have hereunto set my hand and seal this
Seventeenth day of June in the year of our Lord One thousand eight
hundred and eighty two.
