by His Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Tenth day of
November, in the forty-second year of His reign, give and grant unto me,
the said Stephen Hooper, His especial licence, that I, the said Stephen
Hooper, during the term of years therein mentioned, should and lawfully might
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN NEW OR IMPROVED MACHINES OR.
MACHINERY FOR THE PURPOSE OF CLEANSING HARBOURS, CREEKS, RIVERS, GRAIN,
ETCA;" in which said Letters Patent there is contained a proviso obliging me,
the said Stephen Hooper, by an instrument in writing under my hand and
seal, to cause a particular description of my said Invention, and in what
manner the same is to be performed, to be enrolled in His Majesty's High
Court of Chancery within one calendar month after the date of the sai
'd'

page_text: recited Letters Patent, as in and by the same (relation being thereunto had)
may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Stephen Hooper, do hereby declare that my said Invention, and in what
manner the same is to be performed, is particularly described and ascertained
by the above Drawings and explanation thereof.
In witness whereof, I, the said Stephen Hooper, have hereunto set my
hand and seal, the Ninth day of December, One thousand eight
hundred and one
Figure 1, a machine for driving or scowering away banks or sholes in
rivers, or any other places, by means of the current or tide, or rise and fall of
the water. A, A, a barge or vessel riding at an anchor. B, a water wheel,
described in Figure 2, fixed in a frame C, C; the two sides of the upper part
of this frame are made fast to one side of the barge with a prop or pole D to
confine it up against the tide; the wheel to be kept just under water, with the
side or flat part facing the tide, which will give it the greatest power. This
power is communicated by a rod or shaft E, with an universal joint b, b, one
end of which is connected with the shaft of the water wheel B; the other end
is connected to a shaft working in two arbours a, a: At the other end of this
shaft is a bevel wheel F, which works into a bevel wheel G. This wheel G
is. made fast to the main shaft of another wheel H, for raising or lifting of
water out of a well made in the barge or vessel between two bulkheads, as
seen at the dotted lines c, c, made tight, with holes in that part of the barge
or vessel to let the water into the well. Altho' the upper part of the wheel H,
as seen in the barge, appears to work above water, it is nevertheless intended
to work nearly or quite under water. The water is raised by means of the
water wheel H, or by pumps, or in any other way, into a reservoir I, I, or
place prepared on board the barge for that purpose, from whence it is con-
veyed into a tunnel K, or it may be immediately pumped into the tunnel,
&c., &c., at the side of the barge or vessel. This tunnel K-is to be of a
length sufficient. to convey the water from. the side of the barge down on the
shoal or bank required to be removed. The tunnel K to be made of wood or
any other fit materials, about two foot square at the upper end, and about
twelve inches at the lower end; the force of water coming out of this end
pointed. down to the parts to be removed drives them away. Wheel B, being
put in motion by the.steam, will likewise be of use in cutting up banks, etc*,
by fixing of ploughs or other kind of machinery to the outer rim of the wheel;

page_text: and pointing the wheel by the frame down to the part required to be removed,
observing to take away the under part of the frame and shortening the lower ends.
Figure 2, the water wheel B.-A, the main shaft, twelve inches more or less
diameter, and six feet more or less long, with a gudgeon at each end to work
in the frame C, C, as per Figure 1. B; B, B, B, four arms locked round
the main shaft. C, C, an inside rim, five fect diameter more or less, six
inches more or less broad, by four inches more or less thick, bolted to the
arms B, B, B, B. D, D, an outer circle or rim, ten feet more or less
diameter, seven inches broad, by three inches thick more or less, the front
edge bolted to the arms B, B, B, B. E, E, sixteen, less or more, floats, five
feet more or less long, two feet more or less broad at the outer end next
circle D, D, and ten inches more or less broad next the inner circle CC.
These floats, made of wood, iron, or any other fit material, of a thickness: to
stand against the force of the water, may be made fast between the two
circles upon an angle of about thirty degrees, or may be made moveable by a
gudgeon fixed in the centres at the end of each float working in centres in the
two circles, these floats being connected together by sixteen, less or more,
levers, to answer the number of floats working upon a pin or gudgeon fastened
on one end towards the outer end of each float, so that by moving of one they
all move in the same proportion, by which means they may be set to work
upon the opposite angle, as occasion may require. Where this wheel is
wanted to work upon a short head of water in a body, the inside circle must
be extended within about eighteen inches of the outer circle, and the floats
about eighteen inches long, and the inner part from the shaft A to the circle
C must be boarded or closed across from side to side to prevent the water
passing through, short floats will do best; likewise in draining of lands, where
the wheel may either be worked perpendicular on the decline or horizontal.
This wheel may likewise be applied to the forcing through the water barges
and other craft, and to various other purposes.
Figure 3, the water wheel H, as described in Figure 2, working in a
pen or bay to carry forward any kind of machinery. A, A, the pen or
bay for the wheel to work in. That part next the wheel to be made upon a
circle of a diameter just sufficient for the wheel to run clear when at work,
to prevent a waste of water. B, the bridge tree to receive the gudgeon
of the front end of the draw beam. C, one end of the draw beam. D; D,
the wheel. This wheel, when applied for, raising of water, may be fixed in a
bay, as above, observing to keep the bay of a height the water is wanted to be
raised to; the opening of the bay for the wheel to, work in must be rather
below the surface of the water. This wheel will do most business when kept

page_text: to work under water. When the water is not a sufficient depth for a high
wheel to work in, and a large quantity of water is required to be raised or
drained, fix two or more wheels of a less diameter abrest of each other in the
same bay; these wheels may all be brought to work by the same power,
the shafts being connected together by geers or otherwise. When the water
is wanted to be raised higher than it can be by the first bay, there may be
another bay fixed as high as the first wheel or wheels will raise the water
into, observing to keep the next range of wheel or wheels just under water, so
that by the continuation of the same method water may be raised to any
heighth required. These wheels may likewise be worked on the decline or
horizontal, the bays the wheels are fixed in being fixed on the same level, and
the other part of the bay perpendicular of a height the water is wanted to be
lifted to.
Figure 4. Where this wheel B is fixed to work upon a stream, and where a
further power is required, it may be increased by two or more wheels A, A,
being connected to work together by rods B with an universal joint at each
end a, a, or by chains C, C, working over Y wheels D, D, or they may be
worked by geers.
..
Figure 5, the worm or screw to force or draw the mud or soil from the
banks, or level the beds of rivers, etc.-This worm may be made of any
dimensions. A, A, the shaft, made upon an octagon eight inches diameter
more or less. B, B, a number of starts morticed into and standing about
eight inches without the shaft, one upon each cant, standing about three inches
distance from each other along the shaft to form the screw, with a rim C, C,
of iron plate, about four inches broad, made fast from one start to the other,
which completes the screw. The rim, start, and shaft may be made of any
proper kind of materials. This worm is put into motion by the face wheel D
to work at the side of a barge or vessel by the force or power of the tide,
the power being communicated to the worm by a shaft E with universal
joints at each end a, a. This worm to be kept to its work on the ground
-by-two-poles F, F, fixed with an eye at the lower end of each pole to work
over gudgeons at each end of the shaft A.
Figure 6, a number of lighters or vessels A, A, A, sunk lengthways within
about ten feet of each other, reaching from side to side of the pen or reservoi
to form a back water. The space between the vessels to be filled up by two
frames B, B, covered with canvas, as specified in my Patent, bearing date
Twenty-third December, One thousand eight hundred; oue side of each frame
made fast to the beads or sterus of the lighters or vessels, the other two sides
to fasten together representing a pair of gates. These frames make so many

page_text: sluices to open and shut occasionally. To the lower rail of these frames
should be fixed a flap about two feet broad, the outer edge to drop on the
mud or soil, to prevent the water running under the frames.
Figure 7, a machine for cleansing the smut or other soil from wheat or any
other grain. A, a cillender, made in two half circles, four feet long by
seventeen inches diameter, more or less, with twelve ribs, more'
or less,
and screwed or fastened together the same as those for dressing flour. The
two first divisions at the head B are covered with strong screen wire to admit
of the dirt but not the wheat going through; two divisions at the tail C are
covered with wire, as before mentioned. The whole of the divisions, except as
aforesaid, may be covered with strong leather or any other fit materials; or it
may be wired from end to end, when the outer part of the wire between the ribs
must be covered with thin leather, or canvas, or other fit material, to prevent
anything passing through the wire excepting at B and C. D, a shaft, four feet
more or less long, with a gudgeon at each end to work in the body of the cylinder.
The shaft to be made upon an octagon five inches more or less through, with
three heads E, E, E, made of about two-inch elm plank about twelve inches
and an half diameter; these heads to be upon twelve cants more or less to
receive twelve boards more or less, each board about one inch thick. Between
each of these boards are fixed cdgeways two, three, or more pieces of strong
leather, the upper or outer edges to stand about three quarters of an inch
above or without the boards. These Icathers to be cut through from the
upper or outer edge of the leather down to the boards crossways, continuing
from end to end at about one eighth of an inch asunder from each other with a
fine tennant screw or other fit instrument. At the lower end of the shaft D
are fixed two iron rings F, F, to screw eight (more or less) brushes to; or
strong hair, or any other kind of brushes made of materials fit for that purpose,
may be fixed from one end of the shaft to the other between the boards, or
upon rings, or otherways. The shaft D may be put in motion by the water
wheel, Figure 2, or by any other power, to cause a circular motion, or by a
motion to turn about half round and back again. The wheat or other grain
is conveyed into the cylinder at B by means of a shoc or otherwise, and in
passing over the wire at B the collar bags or smut balls are broken and the
black dust forced through the wire. G, a hopper fixed over the cylinder
between the third and fourth ribs, where a hole is made of a size sufficient to
convey bran, pollard, chaff, or any other substance that the black or other
dust from the grain may adhere to; this, being worked together with the grain
thro' the cylinder from B to C, cleanses the grain, and in passing over the
wire at C the bran, etc is separated from the wheat.
