CERTAIN IMPROVE- MENTS IN THE MACHINERY AND APPARATUS FOR RAISING, FORCING, CONVEYING, AND DRAWING OFF LIQUIDS
Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME GREETING,
I, the said JouN WORDSWORTH ROBSON, of Limehouse, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Eighth day of September, in the sixth year of Her reign, did give and
grant unto me, the said John Wordsworth Robson, my executors, administra-
tors, and assigns, Her especial licence, full power, sole privilege and authority,
that I, the said John Wordsworth Robson, my executors, administrators, and
assigns, and such others as I, the said John Wordsworth Robson, my executors,
administrators, and assigns, should at any time agree with, and no others, from
time to time and at all times hereafter during the term of years therein men-
tioned, should lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, and also in all Her said
Majesty's Colonies and Plantations abroad, my Invention of "CERTAIN IMPROVE-
MENTS IN THE MACHINERY AND APPARATUS FOR RAISING, FORCING, CONVEYING,
AND DRAWING OFF LIQUIDS;" in which said Letters Patent there is contained
a proviso, that I, the said John Wordsworth Robson, shall cause a particular
description of the nature of my said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, to

page_text: be inrolled in Her said Majesty's High Court of Chancery within six calendar
months next immediately after the date of the said in part recited Letters
Patent, reference being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Wordsworth Robson, do hereby declare the nature of my Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the following description thereof, reference being
had to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say:--
My Invention consists in the construction of a wheel, marked A in the
Drawings hereunto annexed, which is made of boiler plate, or sheet iron, or
any other suitable material, being circular, with four arms firmly bolted to
the external sides, as shewn in Drawing B, in the centre of which arms are
the bearing or axle upon which the wheel revolves. The Drawing C shews the
action of the water upon the wheel as shewn by dotted lines. The weel may
be divided into four partitions, as shewn in Drawing C, or into as many
divisions as will admit the fluid upon a part of circle and discharge the same
upon a horizontal line with the axle or centre of the wheel; the fluid entering
the wheel upon a part of a circle is continually varying its possession; during
the rotation of the wheel the fluid approaching the centre of it becomes raised,
and diverging as it is discharged in a line horizontal to its axis, by which a
preponderating leverage is obtained at this point, as is herein-before describeil;
the air passes from the partitions of the wheel through holes in each side, as
shewn in Drawing A.
The second part of my Invention consists in a pump, as shown in Drawing D,
for raising fluids from any number of reservoirs into one general suction, and
forcing the fluid into a receiver above, to be conveyed through stop-cocks
thereto attached to any number of vessels required. No. 1 is a stop-cock for
the tails or suctions; No. 2 is the general suction chamber; No. 3 is a plate
with six holes of any shape, as shewn in Drawing F, over four of which holes
are placed the valves marked G; from the holes marked 2 and 3 there is a
pipe or passage, shewn by dotted lines in Drawing F; the fluid is drawn through
the suction and stop-cock into the general suction chamber, and from thence
through the hole marked No. 1 into the cylinder marked in Drawing I, by
means of a diaphraam or cap made of leather moulded into the shape shewn
in Drawing K; the cap is composed of several thicknesses of leather or any
other flexible substance, with layers of india rubber between; the flexible cap
is secured on the flange of the cylinder by means of a metal cap or rim, as
shewn in Drawing D. No. 6, the flexible cap has two strong plates placed

page_text: one on each side of the centre, through which passes the end of the piston, and
securely fixed by a nut and screw, as shewn in Drawing D, No. 4; the flexible
cap or diaphraam being raised by the piston vacuum is caused, the water raises
the valve G over hole No. 1 and fills the cylinder; the downward stroke. closes
the valve G over the hole No. 1, and forces the fluid into the pipe or passage
shewn by dotted lines, through the hole No. 2, raising the valve G over the
hole No. 3 into the receiver No. 5, as shewn in Drawing D, through stop-
cocks thereto attached. The Drawing A shews a wheel with the pump
required for filling the partitions in order to place the machine in equilibrium,
when a small power will keep it in rotary motion.
Having now described the nature of this part of my said Invention, and in
what manner the same is and may be performed, I wish it to be understood
that I do not claim the exclusive use of any of the separate parts above
mentioned and referred to, except so far as the same may be used in com-
bination for the purposes of my said Invention; one part of which I declare
to consist in the construction of a wheel for raising water, whereby the water
contained in the partitions formed in the wheel is continually varying its
position during the rotation of the wheel, the fluid approaching the centre as
it becomes raised, and diverging as it is discharged in a line horizontal to its
axis, by which a preponderating leverage is obtained at this point, as herein-
before described and represented by the Drawings.
Having now described the nature of the second part of my said Invention,
and in what manner the same is to be and may be performed, I wish it to be
understood that I do not claim the exclusive use of any of the separate parts
above mentioned and referred to, except so far as the same may be used in
combination for the purposes of my said Invention; another part of which
I declare to consist in the particular combination and arrangement of parts
lastly above described for the construction of a pump for raising and forcing
liquids.
And further I claim the application of india-rubber, whether in solution or
sheets, to diaphraams or pistons of leather, as described and represented,
whereby a more perfect vacuum can be obtained than by the use of leather
only.
In witness whereof, I, the said John Wordsworth Robson, have here-
unto set my hand and seal, this Seventh day of March, One thousand
eight hundred and forty-three.
(L.S.) J. W. ROBSON.

page_text: AND BE IT REMEMBERED, that on the Seventh day of March, in the
sixth year of the reign of Her Majesty Queen Victoria, the said John Words-
worth Robson came before our said Lady the Queen in Her Chancery, and
acknowledged the instrument aforesaid, and all and every thing therein
contained and specified, in form above written. And also the instrument 5
aforesaid was stamped according to the tenor of the Statute made in the fifty-
fifth 1 year of the reign of His late Majesty King George the Third.
