HODGSON BRAITHWAITE and WILLIAM BRAITHWAITE, of Swinegate, Leeds, in the
County of York. "IMPROVEMENTS IN THE SUPPLY OF WATER FOR WATER
CLOSETS, ETCETERA."
This Invention relates to an improved method of charging syphons used in
flushing waterclosets or urinals, and for similar purposes. Its object is to obviate
the necessity of having any holes, valves, or outlets in the sides or bottoms of
service cisterns, and thus to prevent the possibility of any waste of water.
The syphons used generally pass over the sides of the service cisterns.
In one form of the Invention the shorter leg of the syphon is connected to the
upper portion of a chamber in which a piston or bucket is worked by means of a
rod passing through a closed cover. The chamber is fixed inside the service cistern,
and the piston has a valve inserted in it opening upwards. By raising the piston
the water is forced up the syphon, over the side of the cistern, and the syphon
being thereby charged continues to draw its supply through the valve in the piston
until the water is drawn below the inlet to the chamber.
In the second form of this Invention the chamber is similar to that last
described, but the valve in the piston or bucket is dispensed with. The shorter
leg of the syphon is enlarged to admit of a pipe being inserted and continued within
it to the point where the syphon begins to descend. The pipe so inserted is con-
nected to the upper portion of the chamber. By raising the piston the water is
forced up the internal pipe over the side of the cistern, the syphon is thereby
charged and continues to draw its supply through the space between the inside of
the syphon and the outside of the internal pipe until the water is drawn below the
orifice of the syphon.
In the third form of this Invention the piston, the syphon, and the internal pipe
are of similar construction to those last described, but the chamber has no cover..

This Invention relates to an improved method of charging syphons used in
flushing water closets or urinals, and for similar purposes.
Its object is to obviate the necessity of having any holes, valves, or outlets in
the sides or bottoms of service cisterns, and thus to prevent the possibility of any
waste of water.
The syphons used generally pass over the sides of the service cisterns. In one
form of the Invention the shorter leg of the syphon is connected to the upper
portion of a chamber in which a piston is worked by means of a red passing
through a closed cover. The chamber is fixed inside the service cistern, and the
piston has a valve inserted in it opening upwards. By raising the piston the water
is forced up the syphon, over the side of the cistern, and the syphon being thereby
charged continues to draw its supply through the valve in the piston until the
water is drawn below the inlet to the chamber.
In another form of the Invention the chamber is similar to that last described,
but the valve in the piston or bucket is dispensed with. The shorter leg of the
syphon is enlarged to admit of a pipe being inserted and continued within it to
the point where the syphon begins to descend. The pipe so inserted is connected
to the upper portion of the chamber. By raising the piston the water is forced
up the internal pipe over the side of the cistern, the syphon is thereby charged
and continues to draw its supply through the space between the inside of the
syphon and the outside of the internal pipe until the water is drawn below the
orifice of the syphon.
In another form of the Invention the chamber and the piston are similar to
those last described, but a pipe from the upper portion of the chamber is joined to
the syphon at the point where it commences to descend. By raising the piston the
water is forced up the pipe from the upper portion of the chamber and fills the
descending leg of the syphon. This draws the water up the shorter leg of
the syphon and charges it, and the action continues until the water is drawn below

the orifice of the syphon. In each of the forms of the Invention before described
the piston or bucket instead of being raised may be pressed downwards.
this is the case the chamber is constructed without any cover, and by connecting
the syphon or pipe to the lower portion of the chamber and making slight varia-
tions in the details of the apparatus, the syphons are charged, and the resultant
action is similar to that before described.
In order that our Invention, and the method of carrying out the same, may
be clearly understood and explained, we have attached hereto a Sheet of
Drawings. Corresponding parts in each Drawing have similar letters of reference.
Figure 1 is an elevation, and Figure 2 is a plan of one form of the Invention.
A is the longer leg of a syphon; B is a chamber; C is a piston. The apparatus is
shown placed in a service cistern having a division across it. In one part of the
cistern an ordinary ball tap is fixed to keep it filled with water up to a given line.
In the division is a small hole capable of passing water through it at any rate
required. The other part of the cistern containing the chamber is constructed to
The longer

leg of the syphon may be made any length and connected directly to the basin or
vessel to be flushed with water. By making the length of the pipe A considerable
a very rapid flow of water through the syphon is created.
The piston C contains a valve opening upwards, formed by a flat plate resting
Or the
upon its upper surface, or of any other simple and well known shape.
parts of the piston itself may be made to act as a valve or valves, or the whole of
the piston may be constructed so as to slide up and down the rod, or be loose upon
it and act as a valve. The piston is. connected by a rod, through a cover, to a
suitable lever having a balance weight upon it, with a wire or chain at the opposite
end. By pulling down the chain the balance weight and the piston C are raised,
the water is forced out of the chamber B up the pipe or shorter leg of the syphon
into the longer leg of the syphon A, and as soon as the leg A is filled below the
level of the water in the service cistern the syphon becomes self acting. The water
is drawn through the holes in the bottom of the chamber B and through the valve
in the piston C until the water in that division of the service cistern is drawn
below the holes at the bottom of the chamber B, when the air which follows fills
the syphon and the action ceases.
This part of the cistern is refilled through the small hole in the division shown,
and the apparatus is again ready for use.
Figure 5 is an elevation, and Figure 6 is a plan of another forin of the Invention.
The pipe E from the upper portion of the chamber B instead of forming a part of
the syphon is carried up inside the syphon. The short leg of the syphon com-
mences above the chamber B. The piston D has no valve in it. On raising the
piston D so much of the water contained in the chamber B is passed up the pipe
E into the longer leg of the syphon A, that it draws after it the water in the
shorter leg of the syphon. This water carries over the summit of the syphon the
small portion of air contained therein, and the syphon continues its action until
the water is drawn below the orifice of the same when the action ceases. A sinall
hole shown at the upper part of the chamber B allows the piston D to descend
gradually. Figure 9 is an elevation, and Figure 10 is a plan of another forin of
the Invention. The action is similar in all respects to that in Figures 5 and 6,
except that the pipe from the upper part of the chamber B instead of passing
inside the syphon is joined to it at the part where the syphon begins to descend.
This plan admits of the shorter leg of the syphon F being carried nearly to the
bottom of the service cistern.
Figure 3 is an elevation, and Figure 4 is a plan of a modification of Figures 1
and 2. The shorter leg of the syphon is connected to the lower portion of the
chamber B. In the bottom is a valve opening upwards, and similar to that in
5 the piston C. The levers are arranged to pull the piston D downward; the water
is thus forced up the shorter leg of the syphon and charges it. The supply of
water is continued through the valve and the holes below the bottom of the

page_text: chamber B. Figures 7 and 8 show the syphon arranged as in Figures 5 and 6,
and Figures 11 and 12 as in Figures 9 and 10, but the pipes are connected to the
lower portion of the chamber B instead of to the upper portion, and the pistons
are pulled down instead of being raised.
The ball tap is shown in one only of the Drawings for the sake of simplicity.
The cisterns may be made of any suitable material or shape, and the levers may
be arranged in any desired form to suit the position or purpose desired.
The pipes may pass through the sides or bottoms of the cisterns, but we prefer
to avoid this, and so remove the liability to leakage and loss of water.
Having now described the nature of our Invention and the method of carrying
the same into effect, we desire it to be understood that we do not confine ourselves
to the precise details described, as they may be varied to suit circumstances, but
what we claim as novel and as our Invention is,-
First. The arrangement of a valve in the piston or in the chamber to permit of
the passage of the water after syphons are charged as described, or any mere modi-
fication thereof.
Second. The arrangement of a pipe leading out of the upper or lower portion of
a chamber into the shorter leg of a syphon, which may be charged with water by
means of the upward or downward motion of a piston in the chamber, as shown
and described, or any mere modification thereof.
Third. The combination of parts, as shown in the Drawings, and substantially
as described.
In witness whereof, we, the said Hodgson Braithwaite and William Braith-
waite, have hereunto set our hands and seals, this Tenth day of March, in
the year of our Lord One thousand eight hundred and eighty.
