CERTAIN IMPROVEMENTS FOR RAISING WATER
Year: 1814

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
SAMPSON, of Acorn Street, Bishopgate Street, London, Millwright, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain and Ireland,
bearing date at Westminster, the Third day of October, in the fifty-fourth
year of His reign, give and grant unto me, the said William Sampson, my
exors, adñiors, and assigns, His especial licence, full power, sole priviledge and
authority, that I, the said William Sampson, my exors, adññors, and assigns,
during the term of years therein expressed, should and lawfully might use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "CERTAIN IMPROVEMENTS FOR RAISING WATER;" in
which said Letters Patent there is contained a proviso that if I, the said William
Sampson, shall not particularly describe and ascertain 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, and cause the same to be inrolled in His
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said Letters Patent, that then the said
Letters Patent should be void, as in and by the same, relation being there-
unto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Sampson, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained as follows; that is to say:-
I do construct and make the barrel of my pump either round or square, or

page_text: of
any
other figure suitable for the barrel of a pump, in order that a piston or
paddle may be worked therein; and at a distance (which may be eight or nine
inches, more or less) from the bottom of the said barrel I do fix a partition,
having an hole in or near the center thereof, and other holes or perforations
therein, which may be six or more or fewer in number, as may be preferred,
and the said last-mentioned holes are fitted up with leathers or moveable stops,
or in such manner as is well known and effectual, to produce in each of the same
the effect of a valve opening upwards; but in all other respects I do make the
said partition water-tight. And further, I do construct and make a piston or
paddle to fit and work in the said barrel, having a valve or valves as aforesaid
therein to open upwards; and I do so place, fit, and adjust the said piston or
paddle that the rod thereof shall be moveable or moved water-tight, or nearly so,
in the hole at or near the center of the aforesaid partition, and that the piston
or paddle itself shall work below the said partition, so that whenever the said
piston or paddle shall be depressed in the pump charged with water, the valves
therein will be opened and afford a passage to the fluid; and whenever the
said piston or paddle shall be raised again the water will be forced upwards
thro' the valves in the partition, and by a repetition of such strokes the water
will continue to be raised and pumped up. And morcover I do apply a spring
or springs to the piston or paddle rod, either of spiral or other form, withinside
the barrel or otherwise, according to the local or other circumstances under
which the force shall or may be required to be exerted, and by means of which
spring or springs the said piston or paddle acquires a tendency to rise, and
when left at liberty does rise and carry up the column of water along within;
and although an operative spring or springs of the kind here described may be
made and applied in various well-known ways, I do most commonly, in works
of moderate dimensions, make use of a worm spring encircling the piston rod,
having one end thereof acting against a nut or stop upon the said rod, and
the other end resting against the partition first herein described.
And, lastly, with regard to the uses and means of applying the powers of
wind or water, or steam, or animal strength, or of any other well-known agent
or first mover, to give effect unto my said Invention, I do declare that the
same are so numerous, so variable, and so well known, that it is not at all
needful to describe the same in this present Writing.
In witness whereof, I, the said William Sampson, have hereunto set my
hand and seal, this Twelfth day of October, in the year of our Lord
One thousand eight hundred and fourteen.
WILLIAM SAMPSON. (L.s.)
