PROVISIONAL SPECIFICATION.
An Improvement in Syphon Cisterns.
1 MILTON SYER of 36 Rye Lane Peckham in the County of Surrey Merchant do
hereby declare the nature of this invention to be as follows:-
In a flushing cistern of any desired capacity I provide a well sinking below the
level of bottom of cistern. In this well 1 fit a flat or most convenient shaped disc
which is attached to a rod or chain. Over the well and forming a top to it I fit a
cover with an outlet connected to a swan neck syphon tube. In this cover of well a
hole is made through which the rod moves which is attached to the disc. Surrounding
the rod are holes in this cover which I shall call ports through which the water passes
to supply the syphon when in action. Under the cover of well is fitted a loose disc of
metal or other suitable material the object of which is to close the ports when the rod
or piston is raised so that the water which is displaced shall pass over the bend of
syphon and drive out the air causing syphon to flow.
Sometimes I dispense with the port holes and I then provide a depending annular
wall to the cover of well but allowing sufficient space between it and the well in
cistern for water way. Inside of this annular wall I place the disc or displacer by
the lifting up of which the water is thrown over the bend of syphon and the air being
driven out the syphonage takes place.
The action is provided the cistern is charged with water or partially charged on
the lever being pulled to which is connected the rod the water in the well of cistern
is thrown over the bend of syphon thus driving out the air and starting the syphon
which discharges the contents of the cistern.

COMPLETE SPECIFICATION.
An Improvement in Syphon Cisterns.
I, MILTON SYER of 36 Rye Lane, Peckham in the County of Surrey Merchant, do
hereby declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:
In a flushing cistern of any desired capacity I provide a well G G sinking below
the level of bottom of cistern. In this well I fit a flat or most convenient shaped
disc E. E which is attached to a rod For chain. Over the well and forming a top to
it I fit a cover B. B. with an outlet connected to a swan neck syphon A A. In this
cover of well a hole is made through which the rod F moves which is attached to the
disc E. E. Surrounding the rod are holes D. D in the cover B. B which I call ports
through which the water passes to supply the syphon when in action. Under the
cover B. B is fitted a loose disc H H made of metal or other suitable material the
object of which is to close the ports D. D-when the rod F is raised so that the water
which is displaced shall pass over the bend of syphon A A and drive out the air
causing syphon to flow. Sometimes I dispense with the ports D. D. and I then
provide a depending annular wall C. C to the cover of well B. B but allowing
sufficient space between it and the well G. G for water way, sufficient space being
left between plunger E E and wall C. C to allow water to flow. Inside of this annular
wall CC I place the disc or displacer E E by the lifting up of which the water is
thrown over the bend of syphon A A and the air being driven out the syphonage takes
place. The action is as follows; The cistern being charged with water, on the lever
being pulled to which is attached the rod F and disc E E the water is displaced from

well G. G and is thrown over the bend of syphon A A driving the air before it and
starting the syphon and the contents of cistern is discharged. When the lever is
pulled the compression of water within the annular cell CC closes the loose disc H. H.
against the ports D. D. thus preventing the escape of water through the ports.
the syphon being started the suction opens the ports and allows the water to pass to
sapply the syphon. The dotted lines show position of cover B. B when the depending
wall C. C is not used.
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 I
claim is―
The combination of the cistern with the syphon A A and cover B. B together with
the well G. G enabling the syphonage to be started at a low head of water, together
with the rod F and disc E. E. port holes D. D and loose disc H H substantially as
and for the purpose set forth. The combination of cistern with syphon A A and
cover B B with depending wall CC together with the rod F and disc E. E. substantially
as and for the purpose set forth.
