TRUVIDIUNAL DI MULTIVATION
Improvements in Appliances for Separating and Purifying Grain,
Seeds, Cements, and the like.
I, CHARLIE CLOUGH of 43 Lower Audley Street, Blackburn, in the County of
Lancaster, Millwright, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in separators or purifiers employed in
the separation of semolina, middlings, cements, seeds, grains, or other like substances
by the use of improved appliances hereinafter described whereby I am enabled to
dispense with fans, blowers, and exhaust draughts as heretofore employed with a
better general result or nearer approach to complete separation and without
damaging the ingredients under operation.
According to this my said invention the material under operation or to be
separated, the coarse from the middling and fine, is fed into a hopper, or receptacle,
at the lower end of which is a flap or door which by screw adjustment or weight
regulates the amount of material passing out of the hopper. Beneath the outlet of
the hopper is a preferably smooth roller of small diameter, and also a guide plate
or shoot, at the lower edge of which shoot is an endless apron or belt carried and
caused to travel by means of two driven cylinders or drums. Above this endless
apron is a second endless apron carried and operated in like mauner to the first,
but slightly less in length, so that although the endless aprons are in contact, the
cylinders or drums carrying same are not lineable or in contact with one another,
consequently the substances carried between the aprons are held by an elastic nip
and the larger bodies are not crushed by passing between a pair of rollers as
heretofore.
The partly ground substances pass through the hopper and down the shoot or
guide plate onto the bottom apron, and so between the bottom and top apron, which
are caused to revolve at a sufficiently high speed to throw, by centrifugal force,
the partly ground substances, in such a manner that the heaviest or most coarse
particles of the substance, that is, say for instance, the semolina, is thrown further
than the next finer grade, or middlings, and the middlings are thrown further than
the dunst or next finer grade, and so on, completely separating the various grades.
When the various qualities or grades of the substance are thrown off the roller,
they fall into different receptacles provided for them, and such receptacles are
divided from one another by adjustable division plate, so constructed that the upper
edges of such plates can readily be brought nearer to, or moved further from the
aprons, so that the receptacles are practically placed in such a position, that
different grades of the substance can be received in distinct divisions, according to
weight, or to the distance the particles are thrown by the aprons.
The different grades of the substance are carried or conveyed by any of the well
known appliances from the receptacles to any required position.
The whole of the apparatus is enclosed in a wooden or other casing.
In some cases, as for instance, where light bodies only are to be separated, the
top apron may be dispensed with.

Improvements in Appliances for Separating and Purifying Grain,
Seeds, Cements, and the like.
I, CHARLIE CLOUGH of 43 Lower Audley Street, Blackburn in the County of
Lancaster, Millwright, 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 improvements in separators, or purifiers employed in
the separation of semolina, middlings, cements, seeds, grains, or other like
substances by the use of improved appliances hereinafter described whereby I am
enabled to dispense with fans, blowers and exhaust draughts as heretofore employed
with a better general result or nearer approach to complete separation and without
damaging the ingredients under operation.
Such being the nature and object of my said invention the following is a
complete description of same, reference being had to the accompanying drawings
in which :-
Fig. 1 is a sectional side elevation of the improved appliances for separating and
purifying grain, seeds, cements, granulated barks, and the like.
Fig. 2 is a similar view to Fig. 1 but shewing a slightly modified form of the
appliances for purpose aforesaid.
Fig. 3 is a sectional side elevation of hopper, and distributor, for use when
separating damp or sticky substances, such as cement or sugar, or irregular shaped
bodies.
According to this my said invention the material under operation or to be
separated the, coarse from the middling and fine, is fed into a hopper, or receptacle 1,
at the lower end of which is a flap or door 2 which is hinged at 3 and by screw-
adjustment and spring 4 (see Fig. 2) or by weight 5 (see Fig. 1) can be opened or
closed and regulated so that the amount of material passing out of the hopper 1 is
controlled. Beneath the outlet 6 of the hopper 1 is a preferably smooth roller 7 of
small diameter, and also a guide plate or shoot 8, at the lower edge of which shoot
is an endless apron or belt 9 carried and caused to travel by means of two driven
cylinders or drums 10, 10. Above this endless apron 9 is a second endless apron 11
carried and operated in like manner to the first but slightly less in length so that
although the endless aprons 9. 11 are in contact the cylinders or drums 10, 10
carrying same, are not lineable or in contact with one another consequently the
substances carried between the aprons 9. 11 are held by an elastic nip and the
larger bodies are not crushed by passing between a pair of rollers as heretofore.
The partly ground substances pass through the hopper 1 and down the shoot or
guide plate 8 onto the bottom apron 9 and so between the bottom apron 9 and top
apron 11, which aprons are caused to travel at a sufficiently high speed to throw
off, the partly ground substances, in such a manner that the heaviest or most coarse
particles of the substances, that is to say for instance the semolina, is thrown further,
than the next finer grade, or middlings, and the middlings are thrown further than
the dunst or next finer grade and so on completely separating the various grades.
In some cases particularly where only light bodies are to be separated the top
apron 11 is dispensed with (see Fig. 2) and the substance to be separated falls from
the shoot 8 on to the two rollers 12. 12 which are preferably fluted, and driven in
reverse directions, and the substance is thereby disintegrated before falling onto
the apron 9 by which it is carried forward and thrown as herein before described.
When the various qualities or grades of the substance are thrown off the apron 9
or from between the aprons 9. 11 they fall into different receptacles 13. 14. 15
and 16 provided for them, and such receptacles are divided from one another by
adjustable division plates 17. 17 so constructed that the upper edges of such
plates 17 can readily be brought nearer to or moved further from the aprons 9. 11

page_text: by turning the screwed vertical rods 18 resting in the footsteps 19 and so raising or
lowering the said division plates 17 which are carried by the screwed lugs 20
through which the rods 18 pass.
By this means the receptacles are practically arranged in such a position that
different grades of the substance can be received in distinct divisions according to
weight or to the distance the particles are thrown by the aprons.
The different grades of the substance are carried or conveyed by any of the well
known appliances from the receptacles to any required position.
For feeding some classes of substances such as grain, and irregular shaped bodies
sugar, and cement, I prefer to use a hopper such as is illustrated by Fig. 3 in
which a sleeve 20A is free to be adjusted by sliding up or down on the neck of the
hopper, and can be fixed in the desired position by the winged nut and bolt 21.
Beneath the sleeve 20 is a table, sieve or shoot 22 to which is imparted a
vibrating or shaking motion by means of cams or tappets 23 carried on a shaft 24
and driven from any going part. The cams or tappets may be applied to the sides
of the table shoot or sieve. The substance falling onto the table sieve or shoot 22
is shaken and evenly distributed on the apron 9.
The sieve 22 may be made with one longitudinal half or portion of one size of
holes or perforations, and the other half with holes or perforations of a different
size so that the substances are partly separated by this sieve before falling onto the
apron 9.
The whole of the apparatus is enclosed in a wooden or other casing.
The hopper is in each case made slightly less in width than the width of the
apron.
Having now particularly described and ascertained the nature and object of my said
invention, and in what manner the same is to be performed I declare that what I
claim is :-
1. The general construction, arrangement and combination of parts constituting
the improved separator as herein described and as illustrated by Fig. 1 of the
annexed drawings.
2. The general construction, arrangement and combination of parts_constituting
the improved separator as herein described and as illustrated by Fig. 2 of the
annexed drawings.
