I, THOMAS STEVENS Junior, of Ceres Iron Works, Kingston on Thames, in the
County of Surrey, Engineer, do hereby declare the nature of this invention to be as
follows:-
I 1
My invention relates to machines for cleaning, brushing, and polishing malt and
other grain and particularly to such machines where circular revolving brushes are
employed.
:..
1
According to my invention I place the revolving brush or brushes immediately at
or near to or beneath the sluice in hopper from which the material to be cleaned is
supplied. This brush or brushes is or are caused to revolve at a speed of about
150 revolutions per minute being driven, for example, by hand with multiplying
gearing, or by any other convenient means. There is a concave around the brush or
brushes made of perforated metal or woven wire or of other suitable material, and the
brush or brushes can be adjusted by means of slide bearings to work close up to
the concave or concaves or at any distance therefrom as may be desired or
required.
.'
; 1. .
The action is as follows : Malt or other grain put in the hopper, immediately
runs out of same, anil is caught by the revolving brush or brushes and carried round
and well rubbed against the concave, after which it runs down the screen in the usual
way.
.: f
The object of the brushing is to more effectually remove the "combes
33
or "shives
from malt, than has hitherto been done, also to polish the kernels of malt or other
grain, which is effected by the rubbing action of the brush against the concave which
being of wire-work allows some of the dust and the like to pass through, whilst the
remainder is sifted out by the screen.
A brush or brushes arranged as before described can be applied with advantage
to grain screening machines as now constructed and used by me for some years.
If it should not be desirable to use the brush the board below the brush may bo
removed and laid in a recess provided for the purpose, and so cover over the brush.
The screen is then converted into my usual pattern screen.

Malt and other Grain.
I, THOMAS STEVENS. Junior, of Ceres Iron Works, Kingston-on-Thames, in the
County of Surrey Engineer do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-

My invention relates to machines for cleaning, brushing and polishing malt and
other grain and particularly to such machines where circular revolving ruslies are
employed.

According to my invention I place the revolving brush or brushes immediately at
or near to or beneath the sluice in hopper from which the material to be cleaned is
supplied. This brush or brushes is or are caused to revolve at a speed of about

page_text: 150 revolutions per minute being driven for example by hand with multiplying
gearing, or by any other convenient means. There is a concave around the brush or
brushes made of perforated metal or woven wire or of other suitable material, and the
brush or brushes can be adjusted by means of slide bearings to work close up to the
concave or concaves or at any distance therefrom as may be desired or required.
Figure 1 of the accompanying drawings is a side elevation.
Figure 2 is a plan and Figure 3 is a longitudinal section of a malt and grain
cleaning machine constructed according to my invention.
Figures 4 and 5 are sectional elevations of the upper or hopper end of the machine
showing particularly the arrangement for screening the grain without and when using
the brush drawn on a larger scale than Figures 1, 2, and 3.
Similar letters of reference refer to like parts in all the figures.
A is the framing of the screen set at an angle as shown and supported at one
end by legs B B and at the other by legs CC the position of which can be
regulated by the chains D D whereby the angle at which the machine is required
to be set can be regulated. E is the hopper for the reception of the grain to be
screened and it is provided at bottom with a slide or sluice E', the position of
which is regulated by a rack connected to same in gear with a toothed quadrant F
on a spindle which is rotated by a hand wheel or equivalent outside the frame, so
that by turning same the position of the partition and consequently the opening
for the feed of the grain to be screened is regulated. G is the brush below
the hopper E mounted on a spindle as shown and working in bearings in the
side frames of the machine. The spindle and brush G are driven by chain passing
round a wheel H on the brush shaft and round another sprocket wheel I driven
by the crank handle J as shown or by other power. K is a concave in which
the brush G revolves. L are the screens made of wire of varying sizes and
extending down and across the frame to the exit. M M are flaps hinged as shown
for regulating the flow of grain as it passes along the screens. N (Figures 4
and 5) is a plate kept in position in grooves running across the machine and when
it is desired that the grain shall not be acted on by the brush G this plate is
placed in the position shown at Figure 4 where it will be seen that the said plate N
then covers the brush G and the grain simply passes over it and down to the
screens below without being touched by the brush but on the contrary when the
grain is to be brushed this plate N is placed in the position shown at Figure 5
where it will be seen that the grain which comes through the hopper is brushed
by the brush G and then passes to the screens below. O is the smut box.
Thus the malt or other grain put in the hopper E immediately runs out of same
through the sluice E¹ and is acted upon by the revolving brush G being well rubbed
.thereby, after which it runs down the screens L in the usual way.
ог
The object of the brushing is to more effectually remove the "combes"
"shives" from malt, than bas hitherto been done, also to polish the kernels of
malt or other grain, which is effected by the rubbing action of the brush against
the concave which being of wire work allows some of the dust and the like to pass
through, whilst the remainder is sifted out by the screen.
A brush or brushes arranged as before described can be applied with advantage
to grain screening machines as now constructed and used by me for some years.
If it should not be desirable to use the brush the board or plate N may be laid
in a recess provided for the purpose and so cover over the brush as shewn at Figure 4.
The screen is then converted into my usual pattern screen.
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 1
claim is :-
:
First In machines for cleaning brushing and polishing malt and other grain the
brush G revolving in the concave K immediately below the sluice E' in hopper Ein
combination with the screens L mounted on an adjustable frame all substantially as
described and illustrated with reference to the accompanying drawings.

page_text: Second: In machines for cleaning, brushing and polishing malt and other grain
the brush G revolving in the concave K in combination with the adjustable plate N
for covering or uncovering the brush G substantially as and for the purposes set
forth.
Third: The general arrangement and combination of mechanism for cleaning
brushing and polishing malt and other grain constructed arranged and operating
substantially as and for the purposes hereinbefore described with reference to the
accompanying drawings.
