PROVISIONAL SPECIFICATION.
Improvements in Water Waste Preventer Cisterns.
I THOMAS ATKINS of The Victoria Foundry Co. Herrick Street Wolver-
hampton Ironfounder do hereby declare the nature of this invention to be as
follows:-
-
An improved flushing cistern comprising an annular syphon with a falling flange
or plate to charge it The syphon consists of a standpipe of a peculiar shape
(Fig. 1A), the middle portion of its length being contracted in its diameter,
covered by an elongated cylindrical bell and attached to it by a bolt and nut (B.)
the bolt being inserted in the upper rim of the standpipe and passing through the
top of the bell.
•
To keep the bell central wings are cast on the standpipe but at different plains
so as to offer as little obstruction to the water as possible (C.).
Surrounding the bell is a wide flange or plate-(D) not attached to it but having
free movement perpendicularly. Normally this flange lies on the bottom of the
cistern, the mouth of the syphon being a little above it, but on being raised and
Buddenly released it by its own weight acts as a piston or dasher to force water into
the syphon to charge it the underside being made somewhat concave to facillitate
this. It is connected to the lever by luuks or hooks of the shape and in the manner
shewn (E) to afford flexibility of movement in its rise and fall.
A modification may consist of an annular syphon as Figure 1. but with the
Hange attached to the bell, and having water inlets for supplying the syphon above
the flauge additional to underneath as in the ordinary way-(Fig. 2. F.).
A modification may consist of an annular syphon as in Figure 1 but having a
dashplate working by its side-(Fig. 3. G).

Improvements in Water Waste Preventer Cisterns.
I THOMAS ATKINS of The Victoria Foundry Co. Heirick Street Wolver- .
hampton Ironfounder 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:—
This invention relates principally to the conformation and method of attaching
to each other the several parts of a flushing cistern, whereby is insured greater
certainty in their operation for effecting a rapid and efficient syphonic action, and a
less liability to get out of order.
These comprise a cistern and lid; an annular syphon, consisting of a stand-pipe
and cylindrical cover; a heavy dash-plate or plunger; and an actuating lever.
The general arrangement and configuration of parts 18 shewn in Fig. 1 of the
accompanying diawings, and which 1 now particularly describe in detail,-
The syphon stand-pipe, (A) which is attached to the cistern in the usual way by
a screw and fly-nut, is of large capacity at its extremities but considerably

page_text: contracted for a portion of its middle length. Near its base are two wings or
projections, one on either side, (A1) each having on its outer edge a further
projecting stud formed to fit in a corresponding slot of the cover.
These wings
serve as a holder for the cover; and to keep it in position. On the upper edge or
lip 18 placed a screw-bolt and nut (A 2) for the purpose of securing the cover
to the stand-pipe, and preventing it from becoming displaced from the wing studs.
The cover (B) is an elongated hollow cylinder closed at one end which forms the
top and which has a hole for the before mentioned screw-bolt through it (B 1). On
the edge of the other, or bottom, end which when in position forms the mouth of
the syphon, and approaches very near to the bottom of the cistern, is formed two
slots (B2) for the reception of the wing studs of the stand-pipe.
The dash-plate or plunger, (C) which normally lies on the bottom of the cistern
surrounding the mouth of the syphon, is a heavy plate fitting loosely in a dependent
well. It has a circular opening through it of a capacity to pass freely over the
syphon cover. It is of oval form circumferentially and has its edges bevelled or
recessed to obviate the ability of obstruction from rust; and further, as regards
the inner edge, to permit the mouth of the syphon being brought nearer to the
bottom of the cistern so as to empty it more completely without at the same time
obstructing the water-way
It is connected to the lever by links in the manner shewn, (D) each link having
a loop formed on its upper end which hangs upon the lever; and a somewhat
broadened hook at the lower end which hooks underneath a recessed bar let into
the plate (C1). Of course these links may be of any other form which will allow
similar flexibility of inovement to the dash plate, as this flexibility of movement
afforded the dash-plate in its rise and fall insures its easy working and reduces the
possibility of friction to the minimum.
The lever (E) is of the forked description of the design shewn, having elongated
trunnione. Its bearings are cast on the inside of the cistern, (E 1) thus making no
break in the upper edge but completely enclosing all parts along which water
might trickle to the outside; and further, allowing the application of loose bushes
to the trunnions The bearings may be formed on a bracket or upon the end of the
Cistern if short trunnions are desired.
A cup or holder to receive an elastic buffer for the lever to cushion against 19
placed on the end of the cistern, (F) for the prevention of vibration and noise
when the lever is actuated.
The water-line is defined by being cast on the interior in relief so as to effectually
prevent the possibility of its becoming obliterated.
A modification may consist of the syphon being placed at the end of the well
and the plunger or dash plate working by its side.
A modification may consist of the plate being attached to the syphon cover, and
having water inlets above it additional to underneath.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what [
claim 18:-
1. The conformation and arrangement of parts of a flushing cistern as shewn in
the accompanying diawings.
2. The conformation of a syphon stand-upe and the method of attachment to
its cover substantially as described, and illustrated in Fig. 1 of the accompanying
drawings.
3. The conformation of a syphon cover, the method of its attachment to a stand-
pipe, and its arrangement for water-way substantially as described, and illustrated
in Figs. 1. 2.
4. The conformation of a dash-plate or plunger and the method for attachment
to the lever substantially as described and set forth.
5. The application of connecting links, their conformation, arrangement, and the
modo of their attachment for connecting a dash-plate or plunger to the lever in a

page_text: flushing cistern substantially as described, and illustrated in the accompanying
drawings.
6. The conformnation and arrangement of lever bearings in a flushing cistern
substantially as described and set forth.
7. The particular arrangement of a holder for an elastic buffer for the lever to
cushion against in a flushing cistern substantially as shewn and described.
