RESE
ROBERT DOUGLAS and LEWIS GRANT, Dunnikier Foundry, Kirkcaldy, Engineers
do hereby declare the nature of this invention to be as follows:-
This Invention is an apparatus for the collection and delivery of the meal or dust
which comes through wire cloth, or perforated sheets, of conical, or other forms of
Rice cleaning machinery, in the process of decortication.
When applied to a vertical conical machine, the casing to which the wire-cloth, or
perforated sheets, are attached is mounted on a raised stool, or projection on a base
plate, having suitable parts turned, or faced. An annular flat plate encircles this stool
or projection, having on its underside a toothed ring, cast, or bolted on, and placed in
such a manner as to be protected from the meal or dust.
The said toothed ring gears with a pinion keyed to a spindle which projects through
the base plate, and is driven by pullies and belt, direct from the main spindle of the
machine, or by any other convenient method.
The annular plate is thus revolved; the meal or dust passing through the wire
cloth or perforated sheet casing falls thereon, and is diverted, and discharged, at a
suitable point, by a fixed scraper, or scrapers, placed at an angle, and close to the upper
face of the revolving plate. Rollers may be applied beneath the said plate to reduce
friction in revolving.
An external casing of sheet iron, or other material, may be placed, or fixed outside
the revolving plate to enclose dust; strips of leather, or other material being applied
to form a cover over the edges of plate.
Alternatively the scraper may be revolved, and the annular plate fixed.

We, ROBERT DOUGLAS and LEWIS GRANT, Dunnikier Foundry, Kirkcaldy, in the
County of Fife, North Britain, Engineers do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement ;-
Our Invention has for its object the collection and delivery of meal or dust which
comes through Wire Cloth or perforated Sheets of Conical, or other forms of Rice
Cleaning Machinery, in the process of decortication.
And in order that our Invention, and the manner of applying the same may be
properly understood, we hereunto append a Sheet of explanatory Drawings, to be here-
after referred to in describing our improvements, shewing one method of applying the
said improvements.
Figure 1 is a vertical section, and Figure 2 is a plan view of a vertical conical
machine with our improvements applied thereto.
The same reference letters are used to mark the same parts in both views when
these letters are repeated.
A is the outer casing of a conical machine, carried by, and fixed to, a stool B, the
body of B being of circular form, and having a flange or base plate for attaching it
to the floor, or framing.
Part of the upper surface of this flange, and the outer periphery of the body of B,
is turned true, and on this is mounted an annular ring, or plate, C, which is free to
revolve round the stool B.
On the under side of C an annular toothed ring D is cast, or fixed, into which a
pinion E gears.
Carrying rollers P may be used to reduce friction.
The spindle F of pinion E projects through the flange, or base plate of B, and on
this projection is fixed a toothed wheel G which gears into, and is driven by the
pinion H running loose on a fixed stud I.
On the eye of H is fixed a pulley J, driven by a belt from pulley K on the main
spindle L of the machine.
The revolving motion of L is thus communicated, in a reduced proportion to annular
ring, or plate C, and the meal or dust passing through the wire cloth, or perforated
material which lines the casing A, falls on C, and is carried round therewith until
arrested by the fixed scraper M, which placed at a suitable angle across, and
touches C.
The meal or dust is by this scraper diverted, and delivered into the side mouth-
piece N from which it is discharged to any convenient place.
An outer casing O may be used to retain the lighter particles of dust.

page_text: Other forms of this Invention may be used.
The casing A may be fixed to C, and revolved therewith; in which case the driving
gear inay he dispensed with, and revolution obtained by the friction of the Rice
against the wire cloth, or other lining material; the speed of revolution being regulated
by governing apparatus, or by friction brake.
In another form, the annular ring, or plate, may be fixed, with a delivery opening
therein, and the scraper or scrapers revolved by being attached to an annular ring,
driven by toothed, or worm gear, or by other convenient method.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim is :
The collection and delivery automatically of the meal or dust produced in the pro-
cess of decortication, or cleaning of rice, in vertical or other machines substantially as
herebefore described by means,
1st. Of a combination of a fixed scraper or scrapers, and a revolving annular ring
or plate, driven by any convenient method.
2nd. By fixing the annular ring or plate to the outer casing of machine, and
revolving these together by gearing, or by friction, regulated as to speed of revolution
by a governor, or by friction brake. A fixed scraper being used to discharge
the meal.
3rd. By fixing the annular ring, or plate, and revolving the scraper or scrapers.
