I THOMAS INGLIS of Junction Flour Mills, Leith, Scotland, Miller do hereby
declare the nature of my Invention for "IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR CLEANING AND SCOURING GRAIN" to be as follows:-
This invention relates to "Improvements in the method of, and apparatus for,
cleaning and scouring grain, by means of friction between discs, having V shaped
concentric grooves, with ribbed surfaces, in conjunction with brushes, and a fan, for
drawing away the dust and dirt.
carry my invention into practise in the following manner :-I employ a steel,
iron, or chilled iron disc, grooved with V shaped concentric grooves, with rounded.
radial ribs on their surfaces, which is caused to rotate, on a shaft in close proximity
to a stationary disc, grooved and ribbed in like manner, fixed to the framing of
the machine; the distance between it and the rotating disc, being capable of
alteration of adjustment as required.-The raised portions of the one dise, are made
to project into the recessed portions of the other, a sufficient space being left for
the passage of the grain, under the necessary friction.-The grain is supplied at or
ncar to the centre of the stationary disc, by a suitable feed arrangement, and passes
between the discs, to their peripheries, into a case covered with wire cloth, through
which the dirt escapes into a hopper, and is led-into a sack or suitable receptacle.-
The grain is not allowed to discharge freely, from the discs, but is retarded by its
filling the case, the discharge spout being from the top of the case, thus giving the
necessary pressure without breaking the grain, the object being to cause the
particles of grain to scour each other. The grain passes down the above mentioned
spout, into the centre of a stationary circular brush, fixed to the framing of the
machine, and is polished by a rotating circular brush, mounted on the spindle of
the above mentioned disc, but adjustable as regards its distance from the stationary
brush.
The grain after passing between and from the brushes, falls into a hopper, or
spout, where it is subjected to the suction of a fun, fixed on the spindle above
mentioned, the dust and dirt is thus drawn away, and discharged into a dust
room.

page_text: The whole is encased in a suitable casing. I do not contine myself to the
employment of one pair of discs, but may use two, or more, on the same spindle,
according to the degree of scouring required to be done, the grain being led from
the top of the casing of the one pair, to the centre of the next.

I THOMAS INGLIS of Junction Flour Mills Leith Scotland Miller do hereby
declare the nature of my Invention for "IMPROVEMENTS IN THE METHOD OF AND

statement:-
APPARATUS FOR CLEANING AND SCOURING GRAIN
This Invention relates to certain "Improvements in the method of and apparatus
for cleaning and scouring grain" by means of friction between discs, having
V shaped concentric grooves with ribbed surfaces, in conjunction with brushes
and a fan for drawing away the dust and dirt.
I carry my invention into practise in the following manner,-which I will now
describe by aid of the accompanying drawings, in which Figure 1 is a sectional
clevation, and Figure 2 is partly an end view and partly a cross section of the
apparatus. Like letters indicate like parts in these figures.
I employ a steel iron or chilled iron disc A, grooved with V shaped concentric
grooves C, with rounded radial ribs D, on their surfaces which is caused to rotate
ou a shaft S, carried in suitable bearings, in close proximity to a stationary disc B,
grooved and ribbed in like manner but fixed to the framing of the machine; the
distance between the surfaces of the discs B, and A, is capable of adjustment as
required, by ordinary means.-
-The raised portions of the disc A, are made to
project into the recessed portions of the disc B, a sufficient space being left for the
passage of the grain, under the necessary friction. The grain is supplied at or near
to the centre of the stationary disc B, by a suitable feed arrangement E, and passes
between the discs A, and B, to their peripheries, into a casing covered with wire
cloth F, through which the dirt escapes into a hopper G, and is led into a sack or
suitable receptacles. The grain is not allowed to discharge freely from the discs
but is retarded by its filling the casing; a discharge spout H is placed at the top of
this casing, through which the grain passes in its discharge from the discs, thus
giving the necessary pressure without breaking the grain, the object being to cause
the particles of grain to scour each other. The grain passes down the above
mentioned spout H, into the centre of a stationary brush K, fixed to the frauning
of the machine, and is polished by a rotary circular brush L, also mounted on the
shaft S; the distances between the brushes K, and L, are also adjustable by
ordinary ineans. The grain after passing between and from the brushes K and L

page_text: falls into a hopper or spout M, where it is subjected to the action of an ordinary
exhausting fan N, fixed on the shaft S, with regulating air valve O, by means of
which the dust and dirt are drawn away, and discharged into a dust room. The
whole is enclosed in a suitable casing. I do not confine myself to the employment
of one pair of discs, but may use two or more on the same spindle, according to
the degree of scouring required to be done, the grain being led from the top of the.
casing of one pair to the centre of the next.
Having now particularly described and ascertained the nature of my said and
in what manner the same is to be performed I declare that what I claim is :—
The arrangement of the stationary disc B, with the corresponding revolving
disc A, in a chamber full of grain, discharging through an outlet arranged at or
near the top of the said chamber, in combination with the stationary brush K, with
the corresponding revolving brush L, and exhaust fan N, substantially as and for
the purposes hereinbefore described and illustrated by aid of the accompanying
drawings.
