PROVISIONAL SPECIFICATION.
A Grain Separator.
LOUIS EVARIST BARBEAU of 64 Mark Lane London E.C. in the County of
Middlesex Gentleman do hereby declare the nature of this invention to be as
follows: :-
An adjustable or nonadjustable self cleaning separating screen for grain, barley,
seeds, and cereals of like constructions, between two aspirations one aspiration before
going on to screens, and the other aspiration after passing screen, and a detaching feed
roll and adjustable disc, and consists of a revolving cylinder A. Fig. 1. of steel or iron
with projections cast thereon or screwed into, or otherwise affixed thereto, straight or
spirally running in connection with an improved adjustable disc B. Fig. 1. with pro-
jections affixed as before described. The loose particles liberated by the action of the
detacher are removed by an aspirator, controllable by valves, which allows the heaviest
material removed to drop into a shaking trough or spout G. Fig. 1. delivering at the
side of the machine. The grain being operated upon then falls on to seive or
riddle C Fig. 1 which removes coarse material, the said grain passing thro' the
seive or riddle C Fig. 1 falls on to seive or riddle D Fig. 1 which also removes waste
particles a little larger than the said grain, which allows the aforesaid grain to fall on
to an adjustable, self-cleaning, and separating screen E Fig. 1 which said screen
consists of longitudinal wires L Fig. 2 riveted or otherwise attached to a series of
cross wires or rods M Fig. 2 placed in a suitable position and at the requisite distances
apart, the aforesaid cross wires or rods being all connected together, and all made
movable by one screw, which opens and closes the longitudinal rods L Fig. 2. Under-
neath the aforesaid longitudinal rods L Fig. 2 is placed a stationary shaft O Fig. 2 on
which are placed washers or collars N Fig. 2 so that, when the wire bed is moving
backwards and forwards the spaces between the longitudinal rods are swept, or cleared
or cleaned, by the stationary washers or collars N Fig. 2 or, in place of the seive or
riddle E Fig. 1 a non-adjustable self-cleaning, and separating screen Fig. 3 may be
substituted at E Fig. 1 which consists of longitudinal wires placed at suitable distances
apart U Fig. 3 for separating the small seeds and dust, between each space is placed
a collar or washer V Fig. 3, and Fig. 4 kept in position by stationary cross bars under
the wire bed, supported on strips of metal or other substance T Fig. 3 and placed
outside the framing containing the said seives or riddles C. D. E. F. Fig. 1. which said
seives or riddles, are placed in wood or other framing and fixed in position by wood
or steel springs, or by rollers placed underneath to which a reciprocating motion is
given by a connecting rod and crank in the ordinary manner. The self-cleaning is
effected by the wire bed being moving backwards and forwards, so that the spaces
between the longitudinal wires are swept or cleared, or cleaned by the stationary
collars or washers V. Figs. 3, 4, every time the bed is reciprocated. The aforesaid
grain passing over the adjustable or non-adjustable screen at E Fig. 1, is delivered
into a second aspirator at H Fig. 1 which separates the light material and dust that
may have escaped the preceding operation. The small seeds and dust passing through
the seive E Fig. 1 is delivered into seive or riddle F¹ Fig. 1 which separates the seeds
of dust and dirt.

LOUIS EVARIST BARBEAU 64 Mark Lane London E.C. in the County of Middlesex
Gentleman 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 :-
This invention relates to a detacher and a combination of aspirating, before and
after screening and separating and sizing by self-cleaning adjustable or non-adjustable
screens all kinds of seeds, grains, cereals and other substances of like construction,
hereinafter called the grain, that requires detaching and separating and consists of a
revolving cylinder A Fig. 1 of steel or iron with projections cast thereon or screwed
into or otherwise affixed thereto straight or spirally of any of the aforesaid materials
running in connection with an improved adjustable disc B Fig. 1 with projections
cast thereon or otherwise affixed thereto and of any of the aforesaid materials. The
loose particles liberated by the action of detacher, are removed by an aspirator
controllable by valves, which allows the heaviest material removed to drop into a
shaking trough or spout G Fig. 1 delivering at the side of the machine. The grain
being operated upon then falls on to seive or riddle C. Fig. 1 which removes coarse
material, the said grain passing through seive or riddle (Fig. 1 falls on to seive or
riddle D Fig. 1 which removes the waste particles a little larger than the said
grain operated on, allowing the aforesaid grain to fall on to an adjustable, self-
cleaning, and separating screen E Fig. 1 which said screen consists of longitudinal
wires or rods L Fig. 2 riveted or otherwise attached to a series of cross wires or
rods M Fig. 2 placed in a suitable position and at the requisite distances apart; the
aforesaid cross wires or rods being connected together, and all made movable by one
screw which opens and closes the longitudinal wires or rods, or instead of the said
grain falling on to the aforesaid adjustable screen E Fig. 1 it may fall on to a non-
adjustable self-cleaning, and separating screen Fig. 3 which consists of longitudinal
wires placed at suitable distances apart U Fig. 3 for separating the said grain operated
on, between each space is a collar or washer V Fig. 3 and Fig. 4 kept in position by
stationary cross bars under the wire bed supported on strips of metal or other material
and placed outside the framing containing the said seives or riddles C D E F Fig. 1
which said seives or riddles C D E F Fig. 1 are fixed in wood or other framing and
placed in position by wood or steel springs or rollers placed underneath, to which a
reciprocating motion is given by a crank and connecting rod in the ordinary manner.
The self-cleaning is effected by the wire bed moving backwards and forwards so that
the spaces between the longitudinal rods are swept or cleaned or cleared by the
stationary collars or washers Fig. 3 and Fig. 4 every time the bed is reciprocated.
The aforesaid grain passing through the. self-cleaning screen falls on to seive, or
riddle F. Fig. I which allows small seeds and other particles and dust to pass through.
The aforesaid grain which is required for use is delivered into a second aspirator
which separates the light material and dust that may have escaped the preceding
operation.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed I declare that what
claim is
3.
دولت
I
1. A combination of screening and separating and sizing by self-cleaning adjustable
or non-adjustable screens all kinds of seeds grains, cereals, and substances of like
construction between two aspirators, one aspirator before going on to screens and the
other aspirator after passing screens.

page_text: 2. A detaching feed roll and improved adjustable disc for cleaning and removing
from the grain all adhering matter before screening and carrying away the sai
matter by an aspirator.
