PROVISIONAL SPECIFICATION.
Improvements in Water Waste Preventers or Apparatus for the
Supply of Water to Closets and other Places.
I, GEORGE JENNINGS, of Palace Wharf, Stangate, Lambeth, in the County of
Surrey, Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in water waste preventers or
apparatus for the supply of water to closets and other places.
The apparatus consists of a cistern of a capacity to contain the measure of water it
is desired to deliver at each action. This cistern can be filled from a larger cistern or
from the service pipe by means of a ball cock.
Within the cistern a bell is fixed, it is bolted to the bottom of the cistern and it
rises considerably above the level at which the water stands when the cistern is full.
There is a cavity or pocket in the bottom of the cistern beneath the bell and by this
cavity or pocket communication is established between the cistern and the interior of
the bell so that as the cistern fills, the water rises also within the hell, the air passing
out from the bell by the delivery pipe.
The delivery pipe passes through the bottom of the cavity or pocket of the cistern
and stands up vertically within the bell above the water level.
On the sides of the cistern are the bearings for an axis which extends across the
cistern from side to side. The axis is provided with two arms and from these con-
necting rods descend, one on either side of the bell; they pass down into the pocket
of the cistern beneath the bell and here they are connected to the two arms of a slider
mounted upon the delivery pipe and moveable up and down upon it. The top of
this slider forms a circular table or disc which loosely fits the lower part of
the bell.
The axis is provided with a third arm which extends over the end of the cistern
and a pull wire or chain is attached to it. By the pull wire or chain partial
rotation can be given to the axis and thereby the slider is raised. The table or disc
of the slider traverses within the cylindrical lower part of the bell which it nearly fits
but not water tight.
At the end of its upward course the table or disc reaches a place where the walls of
the hell diverge outwards.
The action then is as follows:-in its upward movement the disc or table lifts the
water in the bell filling the upper part thereof.
At the same time water drawn from the cavity or pocket follows the upward
movement of the disc or table whilst water from the cistern descends into the cavity
or pocket.
The water above the disc flows down the delivery pipe and thereby a siphon like
action is established.
The table or disc now passes into the enlargement at the upper part of the bell
which allows the water to pass freely from its under to the upper side.
The siphon action continues until the cistern is empty and the slider then returns
by its own weight to its original position.
The cistern then again fills by the ball cock and all is ready for another action.
Dated this 12th day of January 1889.

I, GEORGE JENNINGS of Palace Wharf Stangate Lambeth in the County of Surrey
Sanitary Engineer 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 its object improvements in water waste preventers or
apparatus for the supply of water to closets and other places.
The apparatus consists of a cistern of a capacity to contain the measure of water
it is desired to deliver at each action. This cistern can be filled from a larger cistern
or from the service pipe by means of a ball cock.
Within the cistern a bell is fixed, it is bolted to the bottom of the cistern and it
rises considerably above the level, at which the water stands when the cistern is full.
There is a cavity or pocket in the bottom of the cistern beneath the bell and by this
cavity or pocket communication is established between the cistern and the interior of
the bell so that as the cistern fills the water rises also within the bell, the air passing
out from the bell by the delivery pipe.
The delivery pipe passes through the bottom of the cavity or pocket of the cistern
and stands up vertically within the bell above the water level.
On the sides of the cistern are the bearings for an axis which extends across the
cistern fom side to side. The axis is provided with two arms and from these con-
necting rods descend one on either side of the bell; they pass down into the pocket
of the cistern beneath the bell and here they are connected to the two arms of a
slider mounted upon the delivery pipe and moveable up and down upon it.
The top
of this slider forms a circular table or disc which loosely fits the lower part of
the bell.
The axis is provided with a third arm which extends over the end of the cistern
ánd a pull wire or chain is attached to it. By the pull wire or chain partial rotation
can be given to the axis and thereby the slider is raised. The table or disc of the
slider traverses within the cylindrical lower part of the bell which it nearly fits but
not water tight.
At the end of its upward course the table or disc reaches a place where the walls
of the bell diverge outwards.
The action then is as follows:-in its upward movement the disc or table lifts the
water in the bell filling the upper part thereof.
At the same time water drawn from the cavity or pocket follows the upward
movement of the disc or table whilst water from the cistern descends into the cavity
or pocket.
The water above the disc flows down the delivery pipe and thereby a siphon like
action is established.
The table or disc now passes into the enlargement at the upper part of the bell which
allows the water to pass freely from its under to the upper side.
The siphon action continues until the cistern is empty and the slider then returns by
its own weight to its original position.
The cistern then again fills by the ball cock and all is ready for another action.
In order that my said Invention may be more fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.

page_text: A. is the cistern provided with a ball cock B. C is a bell fixed to the bottom of the
cistern, its lower pari is of cylindrical form and it has near the top an extension or
swelling CD is a cavity or pocket in the bottom of the cistern below the bell, it
extends in places beyond the bell as shown in Figures 3 and 4. E is the delivery
pipe fixed to the bottom of the cavity or pocket D. F is an axis above the cistern
to which three arms F F and F are fixed. G G are rods connecting the ends of
the arms F F to the slider H mounted on the delivery pipe. The top of the slider
carries a table or disc J which works on the delivery pipe E and loosely fits inside the
bell C.
The action of the apparatus is as follows
When the cistern is full of water and the arm F2 of the lever is depressed by pulling
the chain attached to its upper end the arms F F are raised carrying with them the
connecting rods G G, the slider F and the disc J. The upward motion of the disc J
within the bell raises the water contained in the bell which when its reaches the top
flows down the delivery pipe E, the water from the cistern entering the bell C and
following the dise J. "When the disc J reaches the enlargement C₁ the water behind
it is free to pass round it and escape down the delivery pipe E which it does, a syphon
action having been set up by the water above the disc J. This syphon action continues
until the cistern is empty the slider then returns by its own weight to its original
position. The cistern then again fills by the ball cock and is ready for another
action.
Having now particularly described and ascertained the nature of my said Invention
and in what mannor the same is to be performed I would state that I am aware it is
not new to fix a cylinder inside the cistern and to set up a syphon action by moving a
piston within such cylinder and I therefore make no general claim to this but what I
claim is :-
1. The combination of a cistern a bell or cylinder fixed within it having an extension
passage or swelling near its top, a delivery pipe within the bell or cylinder and a dise
or piston working upon the delivery pipe.
2. The combination of a cistern, a bell or cylinder fixed within it a pocket below
the bell or cylinder and admitting water to it from the cistern a delivery pipe fixed
at the bottom of the pocket and passing upwards within the bell or cylinder, a disc or
piston working upon the delivery pipe and means for actuating the piston.
3. My improved water waste preventer substantially as described and shown in the
drawings.
