CERTAIN IMPROVEMENTS IN PUMPS, ENGINES, MACHINES, OR APPARATUS FOR DRAWING, RAISING, FORCING OR PROPELLING WATER OR OTHER FLUIDS
Year: 1834

page_text: ALFRED NOBLE, of Cross Street, Cherry Garden, Bermondsey, in the County
of Surry, Engineer and Pump Manufacturer, 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 Sixth day of May, in the fourth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
William Alfred Noble, His especial license, full power, sole privilege and
authority, that I, the said William Alfred Noble, my executors, admors, and
assigns, or such others as I, the said William Alfred Noble, 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, the
Town of Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS
IN PUMPS, ENGINES, MACHINES, OR APPARATUS FOR DRAWING, RAISING, FORCING
OR PROPELLING WATER OR OTHER FLUIDS;" in which said Letters Patent is
contained a proviso that I, the said William Alfred Noble, shall cause a parti-
cular 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

page_text: the said in part recited Letters Patent, as in and by the same, referenco
being thereunto bad, will more fully and at large appear.
NOW KNOW YE, that in complianco with the said proviso, ], tlie snid
William Alfred Noble, do hereby declare that the nature of my said Invention,
and the manner in which the same are to be performed, is 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 of Certain Improvements in Pumps, Engines, Machines, or
Apparatus for Drawing, Raising, Forcing, or Propelling Water or other
Fluids consists in having two or more pistons in one cylinder, by which the
pump is enabled to discharge a much greater quantity of water than pumps in
general.
DESCRIPTION OF THE DRAWING.
Figure 1 represents a pump for raising water for the use of ships or other
purposes. A, the lever that works the pump; B, B, the piston rods; C' and
C, two solid pistons; E, the bottom box or valve to the lower piston C³ ;
F, delivery box or valve to the same; G, lower box or valve to admit water
between the pistons; H, delivery box or valve for the pistons C and C²;
I, suction pipe; K, the cylinder; L, the cistern; M, a stuffing box, through
which the rod to the lower piston passes; N, the spout for delivery of water.
On referring to the Drawing it will be seen that on lifting up the lever A
the piston C ascends and the piston C descends, thereby creating double
the space or vacuum with the same motion which could be done with one
piston, and thereby discharging double the quantity of water of any pump
with a single piston. A further vacuum is caused when the piston C is left
up in that part of the cylinder marked K, the water being admitted through
the lower box or valve E, and afterwards forced through the upper box or
valve into the cistern L, and discharged out at the spout N. When the
piston C³ descends, the piston C' ascends, the valve or lower box G opens to
admit the water or other fluid, and on the return of the stroke the water is
forced through the upper box or valve H into the cistern L, and discharged
out at the spout N. A further quantity of water might be discharged by
having three pistons in one barrel, as represented by Figure 2.
a, the
cylinder; b, b, two pistons on one rod; c, an intermediate or middle piston;
d, a close top or flange to cylinder; and e, e, delivery pipes.
This is merely intended to shew that I do not limit my claim of Invention
to two pistons; and it may be further observed, that by adding an air vessel

page_text: to the discharge pipes e, e, I convert this, as well as Figure 1, into a fire-
extinguishing engine, which may be made portable or otherwise, as the
exigence of the case may require.
In witness whereof, I, the said William Alfred Noble, have hereunto
set my hand and seal, this Sixth day of November, in the year of
our Lord One thousand eight hundred and thirty-four.
