We, WILLIAM BEAMES and JAMES WILLIAM MADELEY, trading together as
Beames & Madeley, of Albany Works, Lombard Street, Birmingham, Warwickshire,
do hereby declare the nature of this invention to be as follows:-
Our invention has reference to those syphon flushing-cisterns which are set in
action by a piston or plunger in the short leg of the syphon being moved upwardly to
cause the water to flow down the discharge pipe acting as the long leg of the syphon,
and our said invention consists in the construction, combination and arrangement of
parts hereinafter described.
In carrying out our said invention we arrange in the water cistern a discharge pipe
which stands up from the bottom thereof and has its upper end open and above the
normal water level in the cistern. This pipe extends below the cistern as usual.
Around the discharge pipe and by preference supported from the bottom of the cistern
is an outer casing which is preferably circular when viewed in plan and there is an
annular space between the outer casing and the discharge pipe. The upper end of
the said outer casing is closed and extends above the top of the discharge pipe and the
outer casing forms the short leg of the syphon of which the discharge pipe forms the
long leg. Between the lower end of the outer casing and the bottom of the cistern is
a short space for the flow of water from the outside to the inside of the outer casing.
The lower part of the outer casing is by preference made of considerably larger
diameter than the upper part thereof so as to form a short cylinder in which is a
loosely fitting annular bucket which also fits loosely around the discharge pipe and
can be moved up and down. This bucket is provided with a valve or valves arranged
to open upwardly and is connected, by a forked rod passing through a hole in the top
of the cover, to the rod or chain by which the apparatus is set in action.
The cistern is automatically filled by means of the usual ball-cock or other suitable
means.
The operation of the apparatus above described is as follows:-When the cistern is
filled with water to its norinal level the water lifts the valve or valves in the bucket
and stands at the same level in the annular space between the discharge pipe and the

page_text: outer casing, and the top of the discharge pipe is some distance above the water level.
The proper water level is maintained by the usual overflow or warning pipe. If the
operating rod or chain is free the bucket will have gravitated to near the bottom of
the outer casing. On the bucket being raised by pulling the operating rod or chain
the water above the bucket is raised also and flows down the discharge pipe thus
setting the syphon in action and causing the water to flow through the valve or valves
in the bucket and down the discharge pipe until the water level falls to the level of
the bottom of the outer casing.
The said bucket consists preferably of a galvanized metal ring perforated by holes
through which the water flows and provided on its upper surface with a ring of sheet
copper or other suitable metal large enough to cover the said holes and forming the
valve which is free to rise a certain distance its motion being limited by suitable
stops.
Instead of operating the bucket by a rod passing through a hole in the top of the
outer casing, this hole may be dispensed with and the bucket operated by a rod or
rods passing down the outside of the outer casing and connected to the bucket
underneath.

We, WILLIAM BEAMES, and JAMES WILLIAM MADELEY, trading together as
Beames & Madeley, of Albany Works, Lombard Street, Birmingham, Warwickshire,
Manufacturers, 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 :-
Our invention has reference to those syphon flushing-cisterns which are set in
action by a piston or plunger in the short leg of the syphon being moved upwardly to
cause the water to flow down the discharge pipe acting as the long leg of" the syphon,
and our said invention consists in the construction, combination and arrangement of
parts hereinafter described.
In carrying out our said invention we arrange in the water cistern a discharge pipe
which stands up from the bottom thereof and has its upper end open and above the
normal water level in the cistern. This pipe extends below the cistern as usual.
Around the discharge pipe and by preference supported from the bottom of the cistern
is an outer casing which is bell-shaped and preferably circular when viewed in plan
and there is an annular space between the outer casing and the discharge pipe. The
upper end of the said outer casing is closed and extends above the top of the discharge
pipe and forms the short leg of the syphon of which the discharge pipe forms the long
leg. Between the lower end of the outer casing and the bottom of the cistern is a
short space for the flow of water from the outside to the inside of the outer casing.
The lower part of the outer casing is by preference made of considerably larger
diameter than the other part thereof so as to form a short cylinder in which is a
loosely fitting annular bucket which also fits loosely around the discharge pipe and
can be moved up and down. This bucket is provided with a valve or valves arranged
to open upwardly and is connected by a forked rod passing through a hole in the top
of the cover to the rod or chain by which the apparatus is set in action.
The cistern is automatically filled by means of the usual ball-cock or other suitable
means.
The operation of the apparatus above described is as follows:-When the cistern is
filled with water to its norinal level the water lifts the valve or valves in the bucket
and stands at the same level in the annular space between the discharge pipe and the
outer casing, and the top of the discharge pipe is some distance above the water level.
In case the ball valve leaks the proper water level is maintained by the usual overflow
or warning pipe. If the operating rod or chain is free the bucket will have gravitated
to near the bottom of the outer casing. On the bucket being raised by pulling the
operating rod or chain the water above the bucket is raised also and flows down the
discharge pipe thus setting the syphon in action and causing the water to flow through

page_text: the valve or valves in the bucket and down the discharge pipe until the water leve
falls to the level of the hottom of the outer casing.
The said bucket consists preferably of a galvanized metal ring perforated by holes
through which the water flows and provided on its upper surface with a ring of sheet
copper or other suitable metal large enough to cover the said holes and forming the
valve which is free to rise a certain distance its motion being limited by suitable
stops.
Instead of operating the bucket by a rod passing through a hole in the top of the
outer casing, this hole may be dispensed with and the bucket operated by a rod or
rods passing down the outside of the outer casing and connected to the bucket
underneath.
We will now proceed to describe with reference to the accompanying drawings the
manner in which our said Invention is to be performed.
Fig. 1 represents in sectional olevation a flushing cistern embodying our Invention;
Fig. 2 is a plan of the same with the cover removed; Fig. 3 is a similar view to
Fig. 1 illustrating the operation of the parts; Fig. 4 is a sectional elevation and
Fig. 5 a plan of the bucket and valve of the saine; and Fig. 6 illustrates a
modification of our Invention.
Referring firstly more particularly to Figs. 1, 2, 3, 4 and 5, a is the cistern having
the loose cover a, and is the open topped discharge pipe standing up from the
bottom of the cistern. c is the bell-shaped outer casing surrounding the discharge
pipe and fixed to the bottom of the cistern by the screws dd; there is a space
between the bottom of the outer casing and the bottom-of-the-cistern. is the
annular bucket fitting loosely in the enlarged lower part of the outer casing cand
provided with the valve f which is by preference a ring of sheet copper or other
suitable metal large enough to cover the openings e¹ in the bucket so that it can rise
upwardly. g is the forked rod fixed to the bucket e and having an upper part
which passes through a hole in the top of the outer casing e and is connected to the
lever turning on the fulcrum i and carrying the chain by which the apparatus is
set in action. The valve fis guided vertically by the forked rod g and two studs k k
fixed in the bucket which latter also form stops to prevent the valve rising too far.
Any ball cock or other means may be employed for automatically filling the cistern.
An overflow pipe m is provided as usual to prevent the water rising too high in case
the ball valve should leak.
As the water flows into the cistern it passes under the outer casing c and lifts the
valve fand rises up the annular space between the discharge pipe and the outer
casing c to the same level as the water in the cistern, which, by the ball valve, is
regulated so as to be a little below the top of the discharge pipe. If the operating
chain is free the bucket e will gravitate to near the bottom of the outer casing cas
seen by Fig. 1. On the bucket e being raised by pulling the chain j, as shewn by
Fig. 3, the water in the annular space above the bucket is raised also and flows down
the discharge pipe 6 thus setting the syphon in action, and the water will continue to
flow through the bucket e and past the valve f and down the discharge pipe until
the water level in the cistern fails to the level of the bottom of the outer casing c.
In the modification illustrated by Fig. 6 the bucket e is connected to the lever h
and operated by two rods n n outside the outer casing c connected to the bucket
underneath the cistern a being recessed at a' a² for the lower parts of these rods.
In conclusion we would have it understood that we do not limit ourselves to the
precise details illustrated by the accompanying drawings as the same may be modified
without departing from the nature of our Invention.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1st. The combination with a flushing-cistern having an internal vertical open
topped discharge pipe, of a bell-shaped outer casing fixed over and covering the said

page_text: discharge pipe and provided with an internal annular bucket and means for operating
the said bucket, all substantially as, and for the purposes, hereinbefore set forth.
2nd. The combination with the discharge pipe b, of the bell-shaped outer casing c
provided with the annular bucket e carried by the rods g or n substantially as
described.
3rd. In combination the bucket e and valve f constructed as and for the purposes
