I, HENRY WAINWRIGHT of 8, and 10, Alfred Street, Leeds in the County of
York, Lead and Glass Merchant, do hereby declare the nature of said Invention
for "IMPROVEMENTS IN APPARATUS FOR SUPPLYING WATER TO WATER-CLOSETS,
URINALS, AND FOR SIMILAR PURPOSES, to be as follows :—
This invention relates to an improved arrangement of apparatus for charging
syphons whereby water for flushing the pans of closets, urinals and for similar
purposes, is drawn from the service cistern, the said cistern being of the usual
construction, divided by a partition into what I will call first and second compart-
ments, the first being supplied in the ordinary way by a ball cock. The quantity
required for flushing, passes from the first to the second compartment through an
opening in said partition.
My improvements consist of a valve case or chamber attached to a partially
open topped cylinder, and of a flap or clack valve, situated near to the bottom of
said chamber and opening inwards thereto. This valve forms a communication
between the second compartment of the service cistern and the valve chamber, and
also with the cylinder by means of an opening therein about opposite to the said
valve. The cylinder is provided with a piston or plunger and constitutes what is
known as a force pump. The upward stroke of the piston is effected by means of
a lever provided with a counterweight which raises and balances the same as well
as the connections used for moving it by hand. When the piston is in the upper-
most position, water flows through the valve into the casing or chamber and into
the cylinder.
The short leg of the syphon is connected to the valve casing or chamber and
then passes over the edge of the service cistern to the closet.
When flushing is required, the piston is made to descend, thus causing the flap
or clack valve to close the communication with the second compartment of the
cistern, and the water to pass through the valve casing or chamber, up the short
leg and over the bend of, and charge the syphon, whereupon its drawing action
commences, opens the flap or clack valve and continues to draw the water from the
second compartment of the cistern until it reaches the upper part of the opening
of the valve, thus regulating and determining the quantity of water to be used at
each flushing.
The above arrangement of apparatus not requiring any openings in the cistern,
no leakage or waste of water can take place.

I, HENRY WAINWRIGHT, of 8, and 10 Alfred Street, Leeds in the County of
York Lead and Glass Merchant, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN APPARATUS FOR SUPPLYING WATER TO WATER CLOSETS,
URINALS AND FOR SIMILAR PURPOSES," and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention relates to an improved arrangement of apparatus for charging
siphons whereby water for flushing the pans of water closets, urinals and for
similar purposes, is drawn from the service cistern, the said cistern being of the
usual construction, divided by a partition into what I will call "first" and "second"
compartments, the first being supplied in the ordinary way by a ball cock. The
quantity required for flushing passes from the first to the second compartment
through an opening in said partition.
My improvements consist of a valve case or chamber attached to a partially (or
it may be altogether) open topped cylinder, and a flap or clack valve situated near
to the bottom of (or it may be central with) said chamber, and opening inwards
thereto. This valve forms a communication between the second compartment of
the service cistern' and the valve chamber and also with the cylinder (to which it is
.connected) by means of an opening therein about opposite to the said valve. The
cylinder is provided with a piston or plunger and constitutes what is known as a
force pump. The upward stroke of the piston is effected by means of a lever
provided with a counterweight which raises and balances the same as well as the
connections used for moving it by hand.
When the piston is in the uppermost position, water flows through the valve into
the casing or chamber. and into the cylinder, the piston of which not being an
airtight fit permits any air contained in the cylinder to escape at its periphery.
The short leg of the siphon is connected to the valve casing or chamber, and then
passes over the edge of the service cistern to the closet.
When flushing is required, the piston is caused to descend, (the clack valve at
the same time closes the communication with the second compartment of the
cistern) and the water to pass through the valve casing or chamber, up the short or
first leg and over the bend of, and charge the siphon, whereupon its drawing action
commences, this action causes the flap or clack valve to open, the siphon continues
to draw the water from the second compartment of the cistern until being nearly
exhausted, air enters the valve chamber, upon which the draught of the siphon
ceases, thus automatically regulating and determining the quantity of water to be
used at each flushing.
The above arrangement of apparatus not requiring any openings in the cistern,
no leakage or waste of water can take place.
The second compartment is refilled through a hole in the partition, ready for
another flushing.

Fig. 2, a cross sectional elevation, and Fig. 3, a plan, a, is the first compartment of
the cistern, supplied with water automatically by means of the ball-cock b, and
its float c, d, is the second compartment separated from the first compartment a,

the piston connected to the lever h. The latter and the connections for actuating
it being balanced by the weight i-j, is the valve chamber attached to the cylinder
or barrel f-k, is the flap or clack valve within the chamber j,-, is the inlet for
water to said chamber. To the chamber ; is connected the short or first leg m, of
the siphon, n, is the bend, and o, its long leg which leads to the closet.-p, is the
hole in the partition e, through which the second compartment d, is supplied from
the first one after having been exhausted by the siphon, r, is a chain or rod
terminating with a handle for actuating the lever h, and piston g.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim, in apparatus for supplying water to water closets, and urinals, and for
similar purposes, is
1st The combination with a siphon of a pump barrel provided with a piston, or
plunger, and a valve opening inwards and affording communication to the said
barrel from a tank or cistern substantially as described.
2nd The improved apparatus for supplying water to water closets and urinals and
for similar purposes constructed, arranged and operating substantially as described
with reference to the drawings.
