TOM CLUDERAY, of Bradford, in the County of York. Corn Factor. ⚫ IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CLEANING AND PURIFYING FOREIGN
GRAIN AND SEEDS."
My Invention relates to separating and removing hard stony substances from
foreign grain and seeds by means of a current of water produced by a revolving
beater or fan fitted inside the apparatus. For this purpose I construct an apparatus
formed with a frame, which is made of plates bolted or rivetted together, or the
frame may be made of wood. On the top of the frame I fix a hopper having at the
base a sliding door to regulate the admission of the grain or seeds in the inside of
the apparatus, and underneath the door is fitted a revolving roller, over which the
grain or seed from the hopper falls. Under the roller is fitted a guard to guide
the fall of the grain or seeds in the chamber. in which falls the stony substances, and
to prevent the current of water in this chamber striking the roller, keeping the
roller dry. The front end of the frame is made slanting and inside is fitted a
slanting plate, on which falls the grain or seed. In the back part of the framework
is fitted a beater or fan which is kept revolving by a belt or gear: this fan is
made nearly the width of the apparatus, and the beater or fan is fitted in a chamber
having a circular cover, and the bottom of the chamber is formed with an opening
and with a bent partition, to which is fixed a horizontal partition fitted to an upright
one, forming three chambers in the apparatus. In the chamber between the
upright partition and the slanting front end falls the grain or seed coming from the
hopper, and containing the hard stony substances. Under the bent partition of
the beater or fan is fitted a perforated plate to equalize the current of water in the
bottom chamber. On the top of the frame is fitted a perforated cylinder, in which
works a screw which is driven by gear and pulley. Over this cylinder is fixed the

page_text: water supply pipe, through which flows water, and which falls on the perforated
cylinder top, passing in the cylinder and on the screw, and through the cylinder on
to the horizontal partition. The water then passes through openings on the sides
of the beater or fan casing, and through the opening made in the bottom beater
casing into the bottom chamber and the chamber in which falls the stony
substances.
The grain or seed to be cleansed and purified, falling over the revolving roller, is
caught by the action of the current of water produced by the revolving beater or
fan, which causes the water to flow and ascend the chamber under the hopper; the
stony substances fall in the chamber, and the grain or seeds are carried by the
current of water to an incline fitted to the perforated cylinder, and from there to a
screw, which delivers them cleaned and purified into a suitable receiver.
The bottom of the frame is made slanting towards the front, and made with an
inclined receiver,in which there is fitted a sluice valve and a door actuated by gear to
regulate the discharge of the stony substances, and to get a better control of the
discharge of the water.
Near to the top of the frame is fitted a slanting plate and an open receiver in
which passes straw or any light substances in the grain or seeds. which are
caught by revolving brushes fitted on an endless band, and removed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Tom Cluderay in the Great Seal Patent Office on the 15th November
1877.

The said Invention relates to separating and removing hard stony substances
from foreign grain and seeds by means of a current of water produced by a revolving
beater or fan fitted inside the apparatus. For this purpose I construct an apparatus
formed with a frame, which is made of plates bolted or rivetted together, or the
frame may be made of wood. On the top of the frame I fix a hopper. having at the
base a sliding door to regulate the admission of the grain or seed into the apparatus.
and underneath the door is fitted a revolving roller, over which the grain or seed
from the hopper falls. Under the roller is fitted a guard to guide the fall of the.
grain or seed in the chamber in which falls the stony substances, and to prevent
the water in the chamber striking the roller, keeping the roller dry. The front end
of the frame is made slanting, and inside is fitted a slanting plate, on which falls
the grain or seed. In the back part of the framework is fitted a beater or fan.
which is kept revolving by means of a belt or by gear: this fan is made nearly the
width of the apparatus, and is fitted in a chamber having a circular cover.
bottom of the chamber is formed with an opening and with a bent partition, to
The
which is fixed a horizontal partition fitted to an upright one, thereby forming three
chambers. In the chamber between the upright partition and the slanting front
end falls the grain or seed coming from the hopper, and containing the hard stony
substances. Under the bent partition of the beater or fan is fitted a plate made
with holes to equalize the current of water in the bottom chamber. On the top of
the frame is fitted a perforated cylinder, in which works a screw, which is driven by

page_text: gear and pulley. Over this cylinder is fixed the water supply pipe. through which
Hows water, and which falls on the perforated cylinder top. passing in the cylinder
and on the screw, and through the cylinder on to the horizontal partition: the water
then passes through openings on the sides of the beater or fan casing, and through
an opening made in the bottom part of the casing, from thence the water passes..
into the bottom chamber and the chamber in which falls the stony substances.
The grain or seed to be cleansed and purified, falling over the revolving roller, is
caught by the action of the current of water produced by the revolving beater or
fan, which causes the water to flow and ascend the chamber under the hopper: the
stony substances fall in the chamber, and the grain or seed is carried by the current
of water to an incline fitted under the perforated cylinder, and from thence to a
screw, which delivers it cleaned and purified in a suitable receiver.
The bottom of the frame is made slanting towards the front, and made with an
inclined receiver. in which there is fitted a sluice valve and door actuated by gear
to regulate the discharge of the stony substances, and to get a better control of the
discharge of the water.
Near to the top of the frame is fitted a slanting plate and an open receiver, in
which passes the straw or other light substance coming afrom the grain or seed, and
which is caught by revolving brushes fitted on an endless band. and removed.
But in order to enable my improvements to be better understood I will proceed
to more particularly describe the same by reference to the accompanying Drawing,
in which,
Figure represents a sectional elevation of the improved apparatus; and Figure 2,
plan of the same.
Figure 3 represents a sectional elevation of elevator trough, with screw fitted at
the back of the apparatus.
Figure 4 represents a side elevation of the straw or light substance receiver; and
Figure 5. plan of the same.
Figure 6 represents a front elevation of the fan beaters and Figure 7. a front
view of the stony and hard substance receiver.
Figure 8 represents a front view of the perforated cylinder frame.
Similar letters of reference are used in all the Figures to represent similar parts.
A. frame of the apparatus, made of plates bolted or rivetted together (or it may
be made of wood); on the top of the frame is fitted a hopper B having a sliding
door C to regulate the admission of the grain or seed in the inside of the machine:
underneath the door is fitted a revolving roller D and guard E. guiding the fall of
the grain or seed, and preventing water striking the roller D. Inside the frame are
fitted partitions F and G, forming three chambers H. 1, and J: in the chamber H is
fitted a frame K having a boss L. in which works a shaft M: the other end of this
shaft works in a bearer N fitted to a bearer O. fixed on brackets P. bolted at the
back of the frame: on the shaft M is fitted a drum Q. on which is fixed a perforated
cylinder R, in which is fitted a screw S: the cylinder and screw are actuated by
bevil wheels T. fitted on the shafts M and U: on the shaft U is fitted a drum or
pulley actuated by a strap. Over the perforated cylinder is fitted a water supply
pipe V, through which flows water, which falls on the perforated cylinder, and
through the perforated plates into the chamber H. and from thence through side
openings W made in side plates X of the fan casing, and from thence through an
opening Y into the chamber 1: in this chamber is fitted a plate Z. made with holes
to regulate and equalize the flow of the water; the water passes through the
opening A into the chamber J. The fan or beater B' is actuated by a belt worked
by a drum or pulley C. fitted on the shaft U. which actuates a pulley D' fitted on
the fan shaft E': the fan or beater revolving causes a strong current and the water
to flow and ascend the chamber J. catching the grain or seed in the fall from the
hopper in the chamber. forcing the grain or seed to ascend and pass on the incline
F and from thence in the inside of the perforated cylinder R. and discharged by
means of the screw S into an inclined trough G', in which works a screw II': the
trough is fixed at the back of the frame, and an opening is made in the back plate

page_text: to allow the water discharged from the grain or seed to return to the apparatus.
The cleansed and purified grain or seed is then carried free from water by the screw
II up the trough, and falls into a receiver I', from whence it is removed; the water
passes through a perforated bottom plate B fitted in the trough G¹.
The stony
hard substances and sand fall on to an inclined plate J' fitted in the chamber J, and
are received in a chamber K', fitted with a sluice valve 1, which is opened or shut
by a rod or rods M'. The chamber K¹ is made with a projecting chamber N¹, on
which is fitted a door O' to regulate the discharge of the stony hard substances and
sand; to remove these substances the door is closed, and the sluice valve opened,
which causes the substances to fall in the chamber N. The sluice valve is then
closed and the door opened, and the hard substances and sand removed, by these
means preventing too much of the water escaping from the apparatus. Straw or
any light substances coming from the grain or seed are prevented entering the
apparatus by the inclined plate P', and they pass into a trough Q', fitted at the top
of the frame, and from thence through an opening R' in the side plate of the frame
into a slanting box S¹ bolted on the outside of the plate. In the box S' is fitted a
perforated plate T, on which falls the straw or other light substance, which is
removed and discharged by revolving brushes U₁ fitted on an endless band_
working over rollers W the front roller is actuated by a pulley and strap. The
water flowing through the opening R¹ in the box returns to the apparatus through
an opening X in the side plate of the frame: Z' is an overflow pipe to take away
the excess of water; A2 is à frame, on which is fixed the frame of the apparatus.
Having thus described my improvements, and the best means I am acquainted
with for carrying the same into effect, I would have it understood that I do not
confine myself to the precise details shewn and described, as they may be varied
without departing from the peculiar character of the Invention, but what I do
claim is.
Firstly. The general arrangement, construction, and employment of the improved
apparatus for separating and removing hard stony substances and sand from foreign
grain or seed, substantially as herein-before described and represented in the accom-
panying Drawing.
Secondly. The separation of the hard stony substances and sand from foreign
grain or seed by means of a current of water produced by a revolving fan or beater,
substantially as herein-before described and represented in the annexed Drawing.
In witness whereof. 1, the said Tom Cluderay, have hereto set my hand-
and seal, this Fourteenth day of November, in the year of our Lord One
thousand eight hundred and seventy-seven.
