OF WATER."
Sealed the 1st January 1870, and dated the 16th July 1869.
PROVISIONAL SPECIFICATION left by the said Richard Brown Evered
and Richard Hurst at the Office of the Commissioners of Patents,
with their Petition, on the 16th July 1869.
We, RICHARD BROWN EVERED, of No. 28, Drury Lane, Brass
Founder, and RICHARD HURST, of No. 191, High Holborn, both in
the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR RAISING, FORCING, AND
REGULATING THE FLOW OF WATER," to be as follows:-
This Invention has for its object improvements in apparatus for
raising, forcing, and regulating the flow of water.

page_text: For raising and forcing water we employ a vessel by preference of
cylindrical form and mounted vertically; it is closed at the bottom, and
within it is another cylindrical vessel of smaller dimension, which is
fitted at the bottom with a perforated metal plate covered with a flexible
disc, acting as an outlet valve. At the top of this cylinder is fixed a
metal cap having a stuffing box, through which works a piston rod with a
perforated metal piston upon it fitted to the cylinder and working within
it. The perforations in the piston are covered with a flexible disc or
valve opening downwards. The suction pipe and the outlet pipe are
both fixed at the upper part of the outer cylinder or vessel, and the
suction pipe is fitted with a valve opening inwards. When the appa-
ratus is in action the downstroke of the piston produces a vacuum, and
causes the water to rise and fill the upper part of the inner cylinder.
Whilst the water under the piston is expelled into the outer cylinder or
casing through the valve at the bottom of the inner cylinder it com-
presses the air in the outer casing, and is by the pressure itself driven
out through the outlet pipe in a continuous stream. At the upstroke
no work is done, the valve in the piston opening to let the water pass
through it. In order to regulate the quantity of water passing a valve
when the said valve is lifted from its seat and before it again closes
we cause the lever for actuating the valve to lift first a weighted rod
entering a cylinder, and fitted with a perforated piston with a flap of
india-rubber or leather on its under. side, acting as a valve. The
spindle of the supply valve is connected to this piston in such manner
that when the piston and weighted rod are raised they in the last part
of their motion lift the supply valve off its seat. The stem of the
supply valve passes through a stuffing box in the bottom of the cylinder
into the valve box, which is divided into two parts by a partition, in
which the seat of the supply valve is formed. The supply pipe is
connected beneath this partition and the outlet is above it. When
the valve is raised the water passes both to the outlet, and also through
a valve in the bottom of the cylinder to the space below the piston.
When the lever is released this water prevents the immediate descent
of the piston, and so the valve is held open for a time. There is,
however, a small passage provided past the piston, which consequently
is able slowly to descend, and in doing so it again closes the supply
valve. The connection between the lower part of the piston rod and
the valve is made by forming the rod with a hollow in its end, into

page_text: which the valve spindle enters, and it is retained by a nut and cap,
allowing however some freedom of motion.
Where the regulation of the flow of water is effected by a ball or
float we cause the supply pipe to terminato in a passage at right angles
to it, and open at both ends; it has however a scat formed in it, and
the valve closing the passage is formed at the end of a plunger or plug.
which is inserted at the opposite end of the passage.
The plunger
or plug is fitted with a disc of india-rubber, to prevent the water
passing between its sides, the walls of the passage. The ball lever
is jointed to the side of the passage, which its end enters through a
slot and enters a recess in the plug or plunger, which is thus compelled
to move with it.
In stool valve we use in place of a stuffing box a piece of tube made
of india-rubber or other flexible material to cover the spindle of the
valve. The tube prevents any leakage, friction, or impediment to the
full flow of water.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Brown Evered and Richard Hurst in
the Great Seal Patent Office on the 15th January 1870.

page_text: 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 APPARATUS FOR RAISING, FORCING, AND REGULATING THE
FLOW OF WATER," upon the condition (amongst others) that we, the
said Richard Brown Evered and Richard Hurst, our executors ar
administrators, by an instrument in writing under our or their hands
and seals, or under the hand and seal of one of us or them, should
particularly describe and ascertain 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 Patont Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Brown Evered, on behalf
of myself and the said Richard Hurst, 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 :-
This Invention has for its objcot improvements in apparatus for
raising, forcing, and regulating the flow of water.
For raising and forcing water we employ a vessel by preference of
cylindrical form and mounted vertically; it is closed at the bottom, and
within it is another cylindrical vessel of smaller dimensions, which is
fitted at the bottom with a perforated metal plate covered with a flexible
disc acting as an outlet valve. At the top of this cylinder is fixed a
metal cap having a stuffing box, through which works a piston rod with
a perforated metal piston upon it fitted to the cylinder and working
within it. The perforations in the piston are covered with a flexible
disc or valve opening downwards. The suction pipe and the outlet pipo
are both fixed at the upper part of the outer cylinder or vessel, and the
suction pipe communicates with the inner cylinder, and is fitted with a
valve opening inwards. When the apparatus is in action the down-
stroke of the piston produces a vacuum, and causes the water to rise and
fill the upper part of the inner cylinder, whilst the water under the
piston is expelled into the outer cylinder or casing through the valve at
the bottom of the inner cylinder; it compresses the air in the outer
casing, and it is by the pressure itself driven out through the outlet pipe
in a continuous stream. At the upstroke no work is done, the valve in
the piston opening to let the water pass through it.

a stuffing box on the top of the inner cylinder; d is a perforated bottom
to the cylinder b, fitted externally with a flexible disc valve c; fis a
piston within the cylinder 6; it is perforated and provided with a flexible
disc valve on its under side; g is the piston rod; h is the suction or
inlet pipe, and ' is a flexible disc valve within it opening inwards; % is
the outlet or delivery pipe; it is continued by a passage k¹ to near the
bottom of the cylinder or vessel a.
In order to regulate the quantity of water passing a valve when the
said valve is lifted from its seat and before it again closes we cause
the lever for actuating the valve to lift a weighted rod entering
a cylinder, and fitted with a perforated piston with a flap of india-
rubber or leather on its under side, acting as a valve. The spindle
of the supply valve is connected to this piston in such a manner that
when the piston and weighted rod are raised they in the last part of
their motion lift the supply valve off its seat. The stem of the supply
valve passes through a stuffing box in the bottom of the cylinder into
the valve box, which is divided into two parts by a partition, in which
the seat of the supply valve is formed. The supply pipe is connected
beneath this partition, and the outlet is above it. When the valve is
raised the water passes both to the outlet and also through a valve in the
bottom of the cylinder to the space below the piston. When the lever
is released this water prevents the immediate descent of the piston, and
so the valve is held open for a time. There is however a small passage
provided passed the piston, which consequently is able slowly to descend,
and in doing so it again closes the supply valve. The connection
between the lower part of the piston rod and the valve is made by
forming the rod with a hollow in its end, into which the valve spindle
enters, and is retained by a nut and cap, allowing however some freedom
of motion.
Figure 2 is a vertical section of apparatus thus arranged to regulate
the flow of water. a is a cylinder, mounted on the top of the valve
case b; it contains a piston c, mounted on the weighted rod d; e is the
supply valve; its spindle e' enters a hollow in the end of the rod d, and
by a nut upon it and a cap in the end of the rod the valve is so con-
nected with the rod that when the rod has been lifted some distance it

page_text: commences to open the valve (or if the pressure of the supply be
sufficient to move the valve it may open sooner); f is a stuffing box
between the cylinder a and the valve case b, through which the
spindle e¹ passes; 9 is a valve, opening out of the valve case into the
cylinder a; c'is a valve on the piston c, opening downwards; a¹ is a
stuffing box on the cover of the cylinder a, through which the weighted
d' is a
rod d passes; b' is the inlet passage, and 6 the escape passage;
minute passage, regulated by a screw, by which water can pass from the
lower to the upper surface of the piston.
Where the regulation of the flow of water is effected by a ball or float
we cause the supply pipe to terminate in a passage at right angles to it
and open at both ends; it has however a seat formed in it, and the valve
closing the passage is formed at the end of a plunger or plug, which is
inserted at the opposite end of the passage. The plunger or plug is
fitted with a disc of india-rubber to prevent the water passing between
its sides and the walls of the passage. The ball lever is jointed to the
side of the passage, which its end enters through a slot and enters a
recess in the plug or plunger, which is thus compelled to move with it.

supply pipe; b, a passage at right angles to it, in which it terminates;
this passage is open at both ends, and contains a plunger or plug c with
a valve c¹ at its lower end; ct is a disc of india-rubber on the upper
end of the plunger or plug to prevent the water passing upwards; dis
the float lever jointed to the side of the passage b, and entering a slotted
hole in the plunger or plug c; it acts within this hole in such manner
as to lift or open the valve when the ball or float falls, and to return it
to its seat when the ball or float rises.
Figure 4 represents a similar ball or float valve, but with the valve
arranged to open with in place of against the flow. The fall of the ball
or float here lowers the valve away from its seat, and the rising of the
ball or float lifts and so closes the valve.
In stool valves we use in place of a stuffing, box a piece of tube made
of india-rubber or other flexible material to cover the spindle of the
valve. The tube prevents any leakage, friction, or impediment to the
full flow of water.
Figure 5 is a section of a stool valve thus constructed or a valve
for the supply of water to a closet. a is a water inlet, and, the

page_text: outlet; c is the valve, held down on its seat by a rod d, except when it
is desired that the water shall flow when the rod is lifted; e is an india-
rubber tube, surrounding the rod d and embracing a projection on the
valve, and a corresponding projection on the under side of the cover f,
so as to make a water-tight joint between them, allowing freedom of the
valve to open and close.
In witness whereof, I, the said Richard Brown Evered, have here-
unto set my hand and seal, this Fifteenth day of January, in
the year of our Lord One thousand eight hundred and seventy.
RICHARD BROWN EVERED. (L.S.)
