PROVISIONAL SPECIFICATION.
Improvements in Separators for Middlings 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 by
corn millers, in the separation of semolina, middlings, and the dunst 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 of 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 regulates the
amount of material passing through 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 are a pair of rollers, one above the other, the upper
one being of smaller diameter than the lower one, and these two rollers are pre-
ferably fluted, or one is fluted, and one smooth. The several rollers are driven by
straps and pulleys or gear, and the partly, ground substances pass through the
hopper and down the shoot, or guide plate to and between the two bottom rollers,
the lower one of which is 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 plates so that such plates can
readily be brought nearer to or moved further from the bottom rollers, 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 roller.
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.

COMPLETE SPECIFICATION.
Improvements in Separators for Middlings 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 by

page_text: corn millers in the separation of semolina, middlings and dunst or other like
substances by the use of improved appliances hereinafter described whereby I am
enabled to dispense with fans, blowers and exhaust drafts as heretofore employed
with a better general result or nearer approach to complete separation of 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 are a pair of rollers one above the other and
preferably of the same diameter, or the upper one is of slightly less diameter than
the lower one, and these two rollers are preferably covered with india rubber. The
several rollers are driven by straps and pulleys or gear, and the partly ground
substances pass through the hopper and down the shoot or guide plate to and
between the two bottom rollers 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 for instance, the
semolina, is thrown further than the next finer grade, or middlings and the middlings,
are thrown further that 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 plates so that the upper edges of
such plates can readily be brought nearer to or moved further from the bottom
rollers, 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 rollers.
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.
Such being the nature and object of my said invention the following is a complete.
description of same reference being had to the accompanying drawing in,
which:
Fig. 1 is a sectional side elevation of the improved separator.
According to this my said invention the material under operation or to be
separated the coarser 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 by screw adjustment or weight 3
regulates the amount of material passing out of the hopper 1. Beneath the outlet
of the hopper 1 is a preferably smooth roller 4 of small diameter, and also a guide
plate or shoot 5 at the lower edge of which shoot 5 are a pair of rollers 6. 6. one
above the other, and preferably of the same diameter or the upper one. of slightly
less diameter than the lower one and, these two rollers.6. 6. are preferably covered
with india rubber 7. The several rollers 4. 6. 6 are driven by straps and pulleys or
gear and the partly ground substances pass through the hopper l'and down the shoot
or guide plate 5 to and between the two bottom rollers 6. 6. which are caused to
revolve at a sufficiently high speed (say from 800 revolutions per minute downwards
according to the.material which is under operation) 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 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.
When the various qualities or grades of the substance are thrown off the roller.
they fall into different receptacles 8, 8, provided for them, and such receptacles are
divided from one another by adjustable division plates 9, 9 free to be turned or
moved on their hinges or pins 10. 10 so that the upper edges of such plates can
readily be brought nearer to or moved further from the bottom rollers 6. 6. so that

page_text: the receptacles 8. 8. 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 roller 6. 6.
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 11 and can
be made of varying size and width and is equally advantageous whether employed
for purifying or separating semolina, middlings and the like, or for asperating
wheat oals barley corn, and other grain or seeds and for separating dry granular
substances generally.
The substances are conveyed from the bottom of each receptacle 8. 8 by means
of ordinary conveyors.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner it is to be performed I declare that what I claim is :-
1. The general construction arrangement and combination of the parts constituting
the improved separator as and for the purpose herein described and substantially as
illustrated by the annexed drawings.
2. The hopper 1 shoot or guide 5 rollers 6. 6 and receptacles 8. 8 with or without
the adjustable plates 9.9 all in combination as and for the purpose herein described
and as illustrated by the accompanying drawings.
