Improvements in Water Waste Preventing Cisterns.
I THOMAS PANARIO of 48 Octavia Street Battersea in the county of Surrey Clerk
do hereby declare the nature of this invention to be as follows :-
The object of my invention is so to fit water waste preventing cisterns and with
such appliances that the bends of the syphons through which these cisterns are
emptied may always be above the upper edges of the sides of the cisterns and I
thus render it impossible that any waste of the water can be created by a continuous
flow through these syphons.
To carry out this object in any convenient cistern I place in the usual manner
any suitable syphon through which the cistern is to be emptied and the flush
effected but the bend of this syphon is preferably above the upper edges of the
sides of the cistern and the syphon itself is preferably placed at or about the
centre of the cistern. The water is admitted to the cistern by and through the usual
or other ball valve and in the cistern round the syphon is placed a plate in size
a little smaller than the horizontal area of the cistern the edges of which plate can
very conveniently be bent downwards all round the same or flanges can be connected
thereto and on or in this plate a collar can if desired be formed round the syphon
and one or more valves are fitted to one or more apertures formed in the proper
position or positions in the plate in such wise that these valves can open downwards
only. Across the upper part of the cistern between the syphon and one of the
ends of the same is mounted a bar to which the lever of the pull is connected
and to this bar are also connected preferably two arms from the ends of which
the aforesaid plate is suspended by rods or links in an horizontal position at the
desired elevation in the cistern the balance being maintained by a counterweight
connected to the bar. The ends of the arms are preferably in the central transverse
line of the cistern the desired distance apart and the rods or links are preferably
two in number for each arm both being jointed to the arm in the same position
while their other ends are spread outwards from each other in the length of the
cistern and then connected to the plate by which method of fitting the desired
horizontality of the plate is the more efficiently ensured. When as is perhaps
desirable the lever of the pull is inside the cistern being bent upwards and then
outwards to pass over the end of the same this lever can conveniently act as one
of the aforesaid arms,
The action of this apparatus is as follows.-The cistern is properly filled by and
through the ball valve and the plate therein is suspended at the desired elevation the
valves in which plate are generally now open. When a flush is desired the lever is
depressed by the pull and the plate is forced downwards thereby and these valves
being thus closed the water is caused to flow up the short leg of the syphon filling the
bend thereof and establishing the syphonic action that is to empty the cistern and it
is obvious that as this plate is nearly of the same dimensions as the horizontal area of
the cistern the water below the same can be caused to ascend to a comparatively great
height by the downward movement thereof and therefore the bend of the syphon
can always be above the upper edges of the sides of the cistern and the water above
the plate can flow not only over the edges thereof but also through the valves therein
and the syphonic action is maintained until the cistern is duly emptied when it is
again filled by and through the ball valve but while the pull is held no further flush
can be given.

Improvements in Water Waste Preventing Cisterns.
I THOMAS PANARIO of 48 Octavia Street Battersea in the county of Surrey Clerk
do hereby declare the nature of this invention and in what manner the samo
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of this my invention is so to fit water waste preventing cisterns and with
such appliances that the bends of the syphons through which these cisterns are emptied
may always be above the upper edges of the sides of the cisterns and I thus render it
impossible that any waste of the water can be created by a continuous flow thereof
through these syphons and as in these cisterns I can always fit overflow pipes
any default of the supply valves or other appliances can immediately be detected.
In order the more clearly to explain my invention and in what manner the same is
to be performed I refer to the accompanying drawing in which Figure 1 is a
longitudinal vertical section of an ordinary and common cistern as fitted in accord-
ance with this my invention and Figure 2 is a plan of the same.
In any usual and convenit cistern A. I place in the ordinary manner any suitable
syphon B through which the cistern is to be emptied and the flush effected and I preferably
use that common form and style of syphon for this my invention that is shewn in the
drawing and I also preferably place this syphon at or about the centre of the cistern
and in all cases the syphon B may be and fully to attain the aforesaid great benefit
and advantage of this my invention always would be so constructed that the bend
thereof is above the upper edges of the sides of the cistern A and the water is
admitted to the cistern A by and through the usual hall or other supply valve D.
In the cistern A and round the syphon B therein is fitted a plate E in size and
dimensions a little smaller in all directions than the horizontal area of the cistern but
of a similar shape the edges of which plato E can very conveniently be bent downwards
all round the same or still more conveniently an angled piece F to form a flange can
be connected thereto all round the edges of this plate E and on or in or by the
plate E a collar or sleeve H can if desired be fitted or formed round the syphon Band
an aperture or apertures K is or are made in the proper position or positions in
the piate E whereto or wherewith is or are fitted a valve or valves L in such wise as
to open downwards only.
Across the upper part of the cistern A between the syphon B and one of the ends
of the same is horizontally mounted a rocking bar M whereto the lever N of the
pull P is attached and to this bar M are also attached preferably two arms R from the
ends whereof the aforesaid plate E is suspended in an horizontal position by jointed
rods or links at the desired elevation in the cistern A the balance being maintained
by a counterweight V connected with the bar M. The ends of the arms R are
preferably in the central transverse line of the cistern A the desired distance apart
one being on each side of the syphon B in order to maintain the required horizontality
of the plate E and in order the more efficiently and certainly to ensure this
horizontality I may when I may desire so to do as for example in cisterns with a large
horizontal area joint two rods or links T to the end of each arm R or joint thereto
the bend of a single rod or link of a bell crank shape the lower ends whereof would
be jointed to the plate E at some distance apart in the length of the cistern A. When
as is perhaps desirable the lever N of the pull P is inside the cistern A this lever N
as is shown in the drawing can very conveniently act as one of the aforesaid arms R
or be a continuation of the same and can if necessary be bent upwards and outwards
to pass and work over the end of the cistern A.
An overflow pipe W is preferably fitted to the cistern A at the desired level
therein.
The action of this apparatus is as follows.
The cistern A is properly filled with water by and through the supply valve D and
the pull P having being released the plate E is suspended by the counterweight V at

page_text: the desired clevation in the cistern A which elevation I may mention I prefer not to
make too great that shewn in Figure 1 being very suitable and the valves L have
generally now opened the apertures K in the plate E and the whole apparatus is in
the position shewn in Figure 1. When a flush is desired the lever N is depressed by the
pull P whereby the plate E is forced downwards closing the valves L and therefore
the water below this plate E is forcibly caused to flow up the short leg of the syphon B
filling the bend thereof and establishing the syphonic action that is to empty the
cistern and as this plate E is as is hereinbefore stated nearly of the same dimensions
as the horizontal area of the cistern A this water below the same can be so caused
to ascend to a comparatively great height by the downward movement thereof and
therefore the bend of the syphon B can always be above the upper edges of the sides
of the cistern as is desired and when the syphonic action is so established as aforesaid
the water above the plate E can flow not only over the edges thereof but also and
chiefly through the aperture or apertures K therein as the valve or valves L will
obviously now be opened and thus the flush is maintained until the cistern A is duly
emptied when it is again filled by and through the supply valve D but while the pull
is held it is obvious that no further flush can be given and any default of the
supply valve or other appliances in not shutting the water off when the cistern is
properly filled will immediately be detected by the flow of the water through the
overflow pipe if any or over the upper edges of the sides of the cistern.
Thus according to this my invention and my arrangement of the various parts of
the same the bend of the syphon can at all events always be above the level of the
overflow pipe even if it be not above the upper edges of the sides of the cistern and
therefore in both arrangements any waste of water will immediately be detected as is
desired. The effect of the flanges F if any round the edges of the plate E obviously
is that to a great extent the water will be prevented passing by these edges when the
plate is forced downwards as is herein before described and therefore the aforesaid
consequence of this downward movement of the plate will the more efficiently and
certainly be ensured.
I have thus described and I have shewn in the drawing what I consider to be
the best and most convenient form and style of this my invention and the most
suitable method or manner of operating the same but it is sufficiently obvious that
I do not limit myself thereto for the syphon and the horizontal actuating plate
may be constructed and fitted as may be expedient in each particular case and
this horizontal actuating plate may be operated in manner aforesaid by and through
any usual and suitable appliances, and devices.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is
1. The water waste preventer consisting of the combination in a cistern with or
without an overflow pipe of a syphon the bend whereof is or may be above the
upper edges of the sides of the cistern with an horizontal plate of nearly the same
dimensions as the cistern the depression of which plate fills the bend of the syphon
and starts the syphonic action that empties the cistern substantially as hereinbefore
set forth.
2. In a cistern the combination with a syphon B of a plate E provided with
an aperture or apertures K fitted with a valve or valves L and operated by a
pull P through a lever N rocking bar M arms R and rods or links T and balanced
by a counterweight V substantially as hereinbefore described.
3. The water waste preventing cistern substantially as hereinbefore described
and shewn in the accompanying drawing.
