Improvements in Siphon Cisterns for Water Closets, Urinals, and
the like.
1 LOUIS ALEXANDER SWALE, of 16 Bond Street, Hull, in the County
of York, Plumber, do hereby declare the nature of this invention, to be as
follows:-
The object of my invention is to make a simple construction of siphon cistern
for water closets, urinals, and the like which shall be positive in its suction and
dispense with the unpleasant noise caused by the ordinary siphon cistern.
For the purpose of my invention I carry my discharge pipe up towards the top
of the cistern and down again nearly to the bottom, in the form of an ordinary
siphon; at or near the top of the bend I connect a tap and air pipe which is
carried up above the water level, the tap is actuated by an arm and ordinary ball
or float, so that while the water is in the cistern to a certain height, the siphon is
in suction, but when the water falls to any required level, the tap is turned and air
admitted which breaks the suction and the discharge is stopped without the
unpleasant noise caused by air rushing into the pipe when the water falls below the
siphon end.
The traverse of the arm of the ball or float may be regulated so as to discharge
any required quantity of water.
At the foot of the siphon I connect a pipe at right angles, ending in a valve, to
admit water to start the siphon; the valve cover is attached to one end by a small
lever having its other end abutting upon a spring piston, which serves to keep the
valve closed and watertight.
The apparatus is put in action by the opening of this valve which admits the water
to the siphon, and so puts it in suction when closed again by the spring. The valve
is operated by a rod, chain or by any suitable means.
The valves and tubes forming the siphon arrangement are preferably cast in one
piece.

Improvements in Siphon Cisterns for Water Closets, Urinals, and
the like.
I, LOUIS ALEXANDER SWALE, of 16 Bond Street, Kingston-upon-Hull in the
County of York, Plumber, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to make a more simple construction of siphon
cistern for water closets, urinals and the like, which shall be positive in suction, and
dispense with the unpleasant noise caused by the ordinary siphon cistern.

Fig. 1. shows elevation of cistern with front removed showing my improved siphon
arrangement.
Fig. 2. is a plan of Fig. 1.
Fig. 3. shows elevation of syphon with modification of spring check valve.
Fig. 4. shows detail of valve cover and bracket.
For the purpose of my invention carry my discharge pipe A up towards the
top of the cistern and down again nearly to the bottom in the form of an ordinary
siphon, at or near the top of the bend I connect a tap and air valve B which is
carried up above the water line, the tap is actuated by an arm C, and ordinary
ball or float D, so that while the water is in the cistern to a certain height, the
siphon is in suction, but when the water falls to any required level, the tap is turned
and air admitted, which breaks the suction and the discharge is stopped without the
unpleasant noise caused by air rushing into the pipe when the water falls below
the siphon end.
The said air valve B is actuated by means of a quick threaded spindle E,
having an enlarged end with washer or the like, the valve is provided with a
removable threaded cap F, this cap has an internal quick thread to correspond with
the thread on the spindle E, so that a half turn of the spindle opens or closes the air
inlet G into the siphon A by way of the tap or valve B.
The traverse of the arm of the ball or float D may be regulated so as to discharge
aur required quantity of water, simply by drawing it up through the hole H in the
end of the spindle E made to receive it, thus if the length of the arm is shortened,
by drawing it up through the hole H the drop of the float or ball D is shortened and
the air valve is closed sooner, the flush being stopped when the desired quantity of
water has been discharged; the arın of the float can be fixed at any required height
by means of a screw or the like J.
At the foot of the siphon I connect a pipe K at right angles ending in a valve to
admit water to start the siphon, the valve cover L is attached to one end of a
small lever M, having its other end upon a spring piston N which forces the valve
cover back into position as soon as the counecting rod O for opening the valve
is released, thus keeping the valve closed and water-tight. In place of having
the pipe K at right angles I may have it turned upward see Fig. 3. the valve
cover L fitting flat on the top, and having the spring N working on the connecting
rod O, and prevented from lifting too high by means of a bracket P. The valve
cover has guides R on its underside to prevent it from slipping on one side. The
apparatus is put into action by opening this valve which admits water to the siphon
and so puts it in suction when closed by the spring N.
The valve is operated by a rod, chain or by any suitable means.
The ball tap S for admitting water to the cistern T, is placed near the bottom of
such cistern, so that when the water is running in, it has no distance to fall and thus
does not cause any sound as it runs it. To allow the ball S₁ to float and actuate
the tap, the arm U has to be bent upward so that the ball floats when the cistern
is full and falls as the cistern empties itself.
The boss W on the ball S', to which the arm U is connected, is formed on the
bottom and not on the joining of the two halves as hitherto, the said joining being
horizontal instead of vertical as on the ordinary construction of balls or floats, thus
the said joining is entirely out of water and not liable to be affected by the action of
the acids or the like in the water.
The ball valve S may be provided with a large flange X, to fit against the inside
of cistern so as to prevent it cutting the lead lining.
The action is as follows:-When the cistern is full both the balls or floats are
at or near the top of the water, to put the siphon in suction, the valve cover L
is opened by pulling the chain or the like connected to the lever which operates.
this valve, as the water in the cistern runs out through the siphon to flush

page_text: the closet or the like, both the balls drop, the ball S¹ opens the water tap and thus
admits water into the cistern, and at the same time the ball D opens the air valve B,
by which means air is admitted into the siphon and breaks suction, the water then
running noiselessly into the cistern fills it up again ready for use.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A siphon arrangement for cisterns provided with an air valve B, actuated by
a ball D, connecting rod C and quick threaded spindle E with ball tap for filling
placed near the bottom of the cistern in the manner and for the purposes, substantially
as shown and described.
2. A siphon A, provided with spring check valve L, for starting the siphon and
keeping the valve cover down, substantially as shown and described.
