IMPROVEMENTS IN PUMPS
Year: 1866

page_text: LETTERS PATENT to William Warren, of Alstone, near Cheltenham, in
the County of Gloucester, Machinist and Engineer, for the Invention of
"IMPROVEMENTS IN PUMPS."
Sealed the 7th June 1867, and dated the 8th December 1866.
PROVISIONAL SPECIFICATION left by the said William Warren at the
Office of the Commissioners of Patents, with his Petition, on the 8th
December 1866.
I, WILLIAM WARREN, of Alstone, near Cheltenham, in the County of
Gloucester, Machinist and Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN PUMPS," to be as follows:-
This Invention relates to the arrangement of the lift and foot valves of
pumps, whereby the contents of the pump barrel and feed pipe may be
readily allowed to descend to the source of supply for the purpose of pre-
venting the water or other liquid from freezing by being left in the pipe and
pump barrel, and also to avoid injury to the liquid (such as malt liquor) by
remaining for a considerable length of time in contact with the metallic surfaces
of the feed pipe and pump barrel. For this purpose I so arrange the foot
valve that it can be set open by means of a lever or other mechanical con-
trivance in combination therewith, when the pump bucket or plunger is
caused to descend or pass beyond a given point in the barrel, a moveable stop

page_text: being arranged in connection with the piston rod or pump handle to determine
the amount of movement of the pump bucket when acting to raise water or
other fluid. By the removal of the adjustable stop the pump bucket or
plunger may be caused to descend to such a distance down the barrel of the
pump as to come in contact with the lever or other mechanical contrivance on.
or connected with the foot valve, and thus raise the same, the valve of the
pump bucket being at the same time set open, thus allowing the water or
other fluid to pass down to the source of supply. By replacing the moveable
or adjustable stop, and setting the pump bucket or plunger in motion, the air
will be withdrawn and the water or other liquid again raised and discharged
by the continued action of the pump. The mechanical means employed for
setting the lift and foot valves open and closing the same when required may
be considerably varied without departing from the novelty of my Invention,
which consists in so arranging the lift and foot valves of pumps that they can
be set open or closed when required for the purpose herein-before set forth.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Warren in the Great Seal Patent Office on the
7th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WARREN, of Alstone, near Cheltenham, in the County of Gloucester, Machinist
and Engineer, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of December, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
William Warren, Her special licence that I, the said William Warren, my
executors, administrators, and assigns, or such others as I, the said William
Warren, 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 "IMPROVEMENTS IN
PUMPS," upon the condition (amongst others) that I, the said William
Warren, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was

page_text: then both valves being opened the liquid in the barrel a, and the suction pipe
is free to descend to the source of supply..
Having now described the nature of my Invention, and the manner of
carrying the same into effect as applied to an ordinary form of pump, I
would remark that the construction, form, and arrangement of pumps and
valves to which my improvements are applicable may be greatly varied, and the
arrangement of the moveable stop or its mechanical equivalent may also be
varied and adapted in any convenient manner, as will be readily understood
by a competent workman, without departing from the nature of my Invention,
which consists in so arranging the pump bucket, valves, and other parts of a
pump that the contents of the pump barrel may be discharged when required
in the manner herein shown and described.
In witness whereof, I, the said William Warren, have hereunto set my
hand and seal, this Sixth day of June, in the year of our Lord One
thousand eight hundred and sixty-seven.
Witness,
J. G. TONGUE,
