AN IMPROVEMENT IN THE RISING PIPE AND SUCTION VALVES OF PUMPS
Year: 1855

page_text: LETTERS PATENT to Josiah George Jennings, of Great Charlotte Street,
Blackfriars Road, in the County of Surrey, for the Invention of "AN
IMPROVEMENT IN THE RISING PIPE AND SUCTION VALVES OF PUMPS."
Sealed the 23rd May 1856, and dated the 10th December 1855.
PROVISIONAL SPECIFICATION left by the said Josiah George Jennings'
at the Office of the Commissioners of Patents, with his Petition, on the
10th December 1855.
I, JOSIAH GEORGE JENNINGS, of Great Charlotte Street, Blackfriars Road,
in the County of Surry, do hereby declare the nature of the Invention for.
"AN IMPROVEMENT IN THE RISING PIPE AND SUCTION VALVES OF PUMPS " to be
as follows:-
It is well known that there is considerable difficulty in changing the valves,
at the rising pipes of pumps, in consequence of it being necessary to remove
the lower parts or valve boxes of such rising pipes, in order to remove the
valves, and then to replace or refix the valve boxes after fitting fresh valves
therein. In some cases the valve boxes have been made with doors, in order
more readily to get at the clack valves to remove dirt or impediments to their
proper action.
Now, my improvement consists of attaching the clack valves to the doors
of the valve boxes of rising pipes of pumps, by which on opening and
removing the doors the valves will come away therewith, and on restoring or
refixing the doors the valves or fresh ones will be put into their places.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSIAH
GEORGE JENNINGS, of Great Charlotte Street, Blackfriars Road, in the County
of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of December, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Josiah George Jennings, Her special licence that I, the said Josiah George
Jennings, my executors, administrators, and assigns, or such others as I,
the said Josiah George Jennings, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "AN IMPROVEMENT IN THE RISING PIPE AND SUCTION VALVES OF PUMPS,'
upon the condition (amongst others) that I, the said Josiah George Jennings,
my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Josiah George Jennings, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
It is well known that there is considerable difficulty in changing the valves
of the rising pipes of pumps, in consequence of it being necessary to remove
the lower parts or valve boxes of such rising pipes, in order to remove the
valves, and then to replace or refix the valve boxes after fitting fresh valves
therein. In some cases the valve boxes have been made with doors, in order
more readily to get at the clack valves to remove dirt or impediments to their
proper action.
Now, my improvement consists of attaching the clack valves to the doors of
the valve boxes of the rising pipes of pumps, by which on opening and

page_text: removing the doors the valves will come away therewith, and on restoring
or refixing the doors the valves or fresh ones will be put into their places.
Having thus stated the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a section of so much of the valve box and parts of the
rising or suction pipe of a pump as will enable me to describe my present
improvement. a is the door of the valve box, which is fixed to the box by
screws in the ordinary manner; a¹ is a projection cast or formed on the inner
surface of the door a, to which the leather flap of the valve 6 is fixed by
screws or otherwise, so that when the door of the valve box is removed the
valve b will come away with it, and the parts of the valve may be readily
cleared or renewed, and on restoring or refixing the doors of valve boxes
so constructed the valves or new ones will be readily put into their places
again.
In witness whereof, I, the said Josiah George Jennings, have hereunto
set my hand and seal, this Tenth day of June, in the year of our Lord
One thousand eight hundred and fifty-six.
Witness,
J. G. TONGUE.
JOSIAH GEORGE JENNINGS. (L.S.)
