PROVISIONAL SPECIFICATION.
Improvements in Water-closet Cisterns.
I, GEORGE PALEY of 15, Ribblesdale Place, in the County of Lancaster, Cotton
Spinner and Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in water closet cisterns of the syphon
flush kind in which a specified or pre-determined quantity of water is arranged to
be delivered or discharged from the cistern at each flushing operation.
I employ within and near to one end of a suitably formed cistern an ordinary
syphon pipe the long leg of which passes through the bottom of the cistern and
connected with the flushing pipe in the usual way the short leg of the syphon pipe
extending downwardly to within a suitable distance from the bottom of the cistern.
I also employ a ball cock or tap of the ordinary kind for supplying water to the
cistern.
An outlet hole or overflow pipe is made or fixed in the end of the cistern opposite
to that in which the syphon pipe is placed and is so arranged that the water (or
contents of the cistern) will begin to overflow just before its surface level reaches
up to the under part of the bend of the syphon pipe.
on the
In order to lift or push the water in the cistern up the short leg of the syphon
pipe when the syphoning or emptying of the cistern for flushing purposes is to be
effected employ a swing plate or wing pivoted or hinged at its lower edge
bottom of the cistern (the said swing plate or wing fitting closely the sides and
bottom of the cistern but being so fitted as to be capable of being moved round on
its hinge or pivot freely therein) the upper edge of the said plate or wing being
connected by means of a suitable lever or of a chain or cord passing over a pulley
to a pull handle hanging down over the end of the cistern in the usual manner.
The swing plate or wing in its normal position stands diagonally but when the
flushing is to be effected the said plate is pulled upwardly or drawn towards
the syphon pipe to a more or less vertical position this action or movement of the
plate causing the body of water between the plate or wing and the end of the
cistern to be compressed and therefore its surface level to be raised and carried
above the bend or neck of the syphon pipe and thus to cause the syphoning action
to he started and the cistern to be emptied of its contents.
I provide the lower part of the swing plate or wing with a hinged flap valve so
arranged that after the compression or raising of the water by the movement of the
swing plate or wing herein before referred to and the syphoning operation has been
started the water on the other side of the swing plate or wing may gradually find
its way through the valve opening in the plate or wing to the syphon pipe until the
level of the water throughout the cistern has been lowered below the open end of
the short leg of the syphon pipe as will be well understood.
The swing plate or wing is so mounted or weighted as to fall back to its former
diagonal position when the downward pressure upon the pull handle has been
withdrawn.

Improvements in Water-closet Cisterns.
I, GEORGE PALEY, of 15, Ribblesdale Place, Preston, in the County of
Lancaster, Cotton Spinner and Manufacturer, 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 to improvements in water-closet cisterns of the syphon
flush kind in which a specified or pre-determined quantity of water is arranged to
be delivered or discharged from the cistern at each flushing operation.
I employ within and near to one end of a suitably formed cistern an ordinary
syphon pipe the long leg of which passes through the bottom of the cistern and is
connected with the flushing pipe in the usual way the short leg of the syphon pipe
extending downwardly to within a suitable distance from the bottom of the cistern.
I also employ a ball cock or tap of the ordinary kind for supplying water to the
cistern.
An outlet hole or overflow pipe is made or fixed in the end of the cistern opposite
to that in which the syphon pipe is placed and is so arranged that the water (or
contents of the cistern) will begin to overflow just before its surface level reaches
up to the under part of the bend of the syphon pipe.
In order to lift or push the water in the cistern up the short leg of the syphon
pipe when the syphoning or emptying of the cistern for flushing purposes is to be
effected I employ a swing plate or wing pivoted, hinged or mounted at its lower
edge on the bottom of the cistern (the said swing plate or wing fitting closely the
sides and bottom of the cistern but being so fitted as to be capable of being moved
round on its pivot or hinge freely therein) the upper edge of the said plate or wing
being connected by means of a suitable lever or of a chain or cord passing over a
pulley to a pull handle hanging down over the end of the cistern in the usual
manner. The swing plate or wing in its normal position stands diagonally but
when the flushing is to be effected the said plate is pulled upwardly or drawn
towards the syphon pipe to a more or less vertical position this action or movement
of the plate causing the body of water between the plate or wing and the end of
the cistern adjoining the syphon pipe to be compressed and therefore its surface
level to be raised and carried above the bend or neck of the syphon pipe and thus
to cause the syphoning action to be started and the cistern to be emptied of its
contents.
I provide at the lower part of the swing plate or wing a hinged flap valve so
arranged that after the compression or raising of the water by the movement of the
swing plate or wing hereinbefore described and the syphoning operation has been
started the water on the other side of the swing plate or wing may gradually find
its way through the valve opening in the plate or wing to the syphon pipe until the
level of the water throughout the cistern has been lowered below the open end of
the short leg of the syphon pipe as will be well understood.
The swing plate or wing is so mounted or weighted as to fall back to its former
diagonal position when the downward pressure upon the pull handle has been
withdrawn.
In the accompanying drawings,
Fig. 1 is a side view (with the cistern shewn in section) illustrating the arrange-
ment of my improved apparatus as above described with the water therein at its
normal level or height; and
Fig. 2 is a similar view showing the altered position of the swing plate and the
levels of the water within the cistern when the said swing plate has been pulled or
moved to its more or less vertical position so as to cause the starting of the
syphoning action.
a is the cistern 6 the syphon pipe and c ball cock apparatus of the ordinary kind.

page_text: d is an outlet or overflow pipe. e is the swing plate or wing pivoted at its lower
edge (preferably in the manner shewn) its upper edge being connected by means
of the lever g and chains h h to the pull down handle i. is the hinged flap valve
at the lower part of the swing plate shewn closed at Fig. 1 and open at Fig. 2. In
actual operation however the said flap valve will not open until the level of the
water on the left hand side of the swing plate e has fallen below that on the right
hand side of the said plate.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In water-closet cisterns of the syphon flush kind the use or employment of a
swing plate or wing caused to compress the water within the cistern and thereby to
raise its surface level and to start the flushing operation in manner substantially as
herein before described.
