PROVISIONAL SPECIFICATION.
Improvements connected with Flush Cisterns.
I, EDMUND WARD, of North Cottage, Charlotte Place, Clapham, Surrey,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention has for object, the construction or arrangement of the detail
parts of a flush cistern, so that on the first part of the pull on the cord for discharge,
a siphonic action is established the siphoning being completed automatically,
whether the pull of the cord be to the fullest extent or not.
For the purpose of my invention, 1 make a flush cistern of any desired shape
with a well at the central lower part into which I secure a tube in part with the
downflow socket, said tube being a fixture and of sufficient height as to prevent
escape of any overflow that may happen through the supply tap being leaky from
any cause, the excess then escaping from the cistern into the building in which the
cistern is placed.
The part of the fixed tube which is within the well has a short tube surrounding
it with the lower edge of smaller diameter as almost to touch the fixed' tube. The
short tube has a couple of washer like discs affixed, of different diameters, the
upper or larger having holes through which the body of water from the cistern
during the flushing operation becomes controlled; this short tube is connected by
links or the like to an oscillating lever to which the pull cord is attached..
Surrounding the upper part of the fixed tube and also the washer like discs
at the lower part, is a bell or canopy forming an air chamber for siphoning.
Both ends of the cistern is adapted for the fixation of the water supply tap for
right hand or left hand supply, recesses being also formed for the oscillating lever.
to be arranged to correspond.
By this invention, I ain enabled to dispense with rubber or leather, and all kinds
of valves, and obtain a true siphoning action.

COMPLETE SPECIFICATION.
Improvements connected with Flush Cisterns.
I, EDMUND WARD, of North Cottage, Charlotte Place, Clapham, Surrey,
Plumber, 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 has for object, the construction or arrangement of the detail
parts of a flush cistern, so that on the first part of the pull on the cord for discharge,
a siphonic action is established, the siphoning being completed automatically,
whether the pull of the cord be to the fullest extent or not.
For the purpose of my invention, and as I show on the annexed drawings, I
make a flush cistern A of any desired shape with a well B at the central lower
part, into which I secure a tube C in part with the downflow socket D, said tube C
being a fixture and of sufficient height as to prevent escape of any overflow that
may happen through the supply tap E being leaky from any cause, the excess then
escaping from the cistern by the outlet F to a drain, or into the building in which
the cisteru A is placed.

page_text: -
The part of the fixed tube which is within the well has a short tube G surround-
ing it with the lower edge of, smaller diameter than the remainder as almost to
touch the fixed tube C.. The short tube G has a couple of washer like discs H, I,
affixed, of different diameters, the upper or larger I having holes through which
the body of water from the cistern A during the flushing operation becomes
controlled; this short tube G by rods J, J, is connected by links K, K, or the
like to an oscillating or beam lever L to the extension M of which the pull cord is
attached.
Surrounding the upper part of the fixed tube C and also the washer like.
discs H, I, at the lower part, is a bell or canopy N forming an air chamber for
siphoning. The bell is fixed to the bottom of the cistern as at P, P.
Both ends of the cistern A is adapted for the fixation of the water supply tap E
for right hand, or for left hand supply, recesses being also formed for the pull
lever M to be arranged to correspond.
By this invention, I am enabled to dispense with rubber or leather, and all kinds
of valves, and obtain a true siphoning action.
This flushing cistern has many advantages over existing ones.
1. It is made for right or for left hand supply.
2. It fits close to the wall and does not require bearers.
3. It has less number of parts than usual.
4. It is very compact and reliable in action.
5. The flush operation never jumps or gurgles.
6. It always empties itself to top of well and discharges a fixed quantity.
7. The syphonic action is perfect.
8. There are no valves, rubbers, or leathers to get out of order.
9. Will thoroughly perform its work if fixed only two feet above seat of
closet.
The construction is simple, and consists of a double plunge partly in the "well"
and partly in the "bell" and is the only movable portion operated from the pull
cord and balanced lever.
The "bell" is secured to the top of the "well" with a good clearance for the
passage of water from the cistern.
The cistern can be made in various sizes for capacity.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I 3
claim is :-
1. The described construction of flush cisterns and arranging the various parts
as shown in the drawings.
2. In a flush cistern, the employment of a double disced tube partly within the
cistern well, and partly within the bell for action in the manner shown for the 4
purposes set forth.
