IMPROVE- MENTS IN PUMPS OR MACHINERY FOR RAISING OR FORCING FLUIDS
Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WHELDON, Engineer to Messieurs John Warner and Sons, of Jewin Crescent,
in the City of London, Brass Founders and Engineers.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourth day of September,
One thousand eight hundred and forty-eight, in the twelfth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Wheldon, my exors, adñiors, and assigns, Her especial licence, full
power, sole privilege and authority, that I, the said William Wheldon, my
exors, adiñors, and assigns, and such others as I, the said William Wheldon,
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 "IMPROVE-
MENTS IN PUMPS OR MACHINERY FOR RAISING OR FORCING FLUIDS;" in which said
Letters Patent is contained a proviso that I, the said William Wheldon,
should cause a particular description of the nature of my said Invention, and
the manner in which the same is to be performed, by an instrument in writing
under my hand and seal, to be inrolled in Her 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.

page_text: Figure 1 shews a lift pump suitable for a plank. In this pump the axis of
the vibrating standard is carried by the pump barrel, or the axis may be
carried by the plank.
Figure 2 shews a lift pump, the axis of the vibrating standard being at a
distance above the pump barrel.
Figure 3 shews another lift pump, where the axis of the vibrating standard
is carried by the pump barrel.
Figure 4 shews a pump suitable for a beer engine, the axis of the vibrating
standard being carried by the pamp barrel.
Figure 5 shews a force pump, the axis of the rocking or vibrating standard
being carried by the pump barrel.
And Figure 6 shews an arrangement where the piston is worked by a rod
sliding in sockets or guides, the axis of the vibrating standard being carried by
some convenient surface fixed above the pump barrel.
In all these cases it will be seen the object is to get a rectilinear motion to
the piston rod, by the axis of the lever handle moving to and fro' by means
of the vibrating or rocking standard below such lever, and which carries the
axis of the lever handle.
It will not be necessary to enter into a description of the various parts of
each pump, as they are shewn in the Drawings; and the details of construction
of the pumps may be varied, so long as the peculiar character of the improve-
ments be retained.
In each of the above-mentioned Figures A is the axis of the vibrating or
rocking standard; B is the rocking standard; C is the lever handle for
working the pump, the axis of which is carried at the upper end of the vibrating
standard, and above its own axis of motion; D is the end of the lever handle,
which is put in connection with the piston rod of the pump.

page_text: Figure 7 shews a garden pump, having my improvements applied thereto.
Having thus described the nature of my Invention, and the manner in which
the same is to be performed, I would have it understood that I make no claim
to the mechanical parts separately. But what I claim is,-the mounting of
the axes of lever handles of pumps on the upper parts of vibrating or rocking
standards, the vibrating or rocking standards having their axes of motion below
the axes of motion of the lever pump handles.
In witness whereof, I, the said William Wheldon, have hereunto set
my hand and seal, this Second day of March, in the year of our
Enrolled the Third day of March, in the year of our Lord One thousand
eight hundred and forty-nine.
