IMPROVEMENTS IN PUMPS
Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FUSSELL, of Nunney, in the County of Somerset, Edge Tool Maker, send
greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-ninth day of December, in the sixth year of
His reign, did, for Himself, His heirs and successors, give and grant unto me,
the said John Fussell, His especial licence, full power, sole privilege and
authority, that I, the said John Fussell, my exors, admors, and assigns, or
such others as I, the said John Fussell, my exors, admors, or assigns, should at
any time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN PUMPS;" in which said
Letters Patent is contained a proviso that I, the said John Fussell, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in His said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Fussell, do hereby declare the nature of my Invention, and the manner
in which the same is to be performed, are fully described and ascertained

c, the suction pipe, which
constructions now in use.
a, a, is the ordinary pump barrel; b, the valve at the bottom of such barrel;
parts may be made according to any of the various
d is a vessel proceeding from or opening into the
suction pipe, just below the valve b, and it is the application of this vessel d
which constitutes the first part of my Invention, and the improvements resulting
from such application of the vessel d are as follows:-It is well known that in
working pumps, particularly where the water has to rise or pass from a con-
siderable distance, that the water does not follow to the action of the piston
so quickly as to give full effect to the power employed in working the same.
Now, it will be found by applying my improvements to pumps, the following
effect will take place:-On first working the pump, and consequently before
any water rises in the suction pipe c, the first action of the piston will be to
remove the larger portion of the air from the suction pipe c, and also from
the vessel d, and the water will then rise and fill the suction pipe and the
barrel of the pump a, a, and will for the most part fill the vessel d, the con-
sequence of which will bo that, in the further working of the piston, imme-
diately it commences to rise from the valve b, the water in the vessel d will
more readily pass into the pump barrel than that the whole mass of the water
in the suction pipe c will be put in motion by the pressure of the atmosphere,
but in the descending of the piston in the pump barrel, the water rising up
the suction pipe will enter and again supply the vessel d, and the water therein
will then be ready for the next up stroke of the piston. And it may be
remarked that it is not necessary that the vessel d should be at a distance
from the suction pipe, as it will be evident that the vessel d may surround the
upper part of the suction pipe.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would remark that I do not confine myself to the precise
arrangement here shewn, for the vessel d may be placed in some degree
different, as above noticed, from that shown, and yet obtain the object of my
Invention, that of having a vessel of water the more quickly to supply the
working of the piston in the barrel, as above described.
The second part of my Invention consists in so constructing the piston rods
of pumps that they constitute air vessels. e is a piston rod, constructed
according to my Invention. It consists of a tube from the point c to the

page_text: point f, at which point f the piston rod or tube is closed, and at the end < the
piston rod or tube is open, and the bucket or piston is attached at e. The
consequence of this arrangement will be that the hollow piston rod or tube
will contain a quantity of air, which will in the working of the pump pro-
duce an uniformity of flow of water from such pump in like manner to an
ordinary air vessel, which has been commonly applied to hydraulic machines.
In witness whereof, I, the said John Fussell, have hereunto set my
hand and seal, this Twenty-third day of June, in the year of our
Lord One thousand eight hundred and thirty-six.
