A WATER WASTE PREVENTER CISTERN FOR WATER CLOSETS
Year: 1885

page_text: I ROBERT OATES of 72 Portland Crescent Leeds in the County of York, Plumber
do hereby declare the nature of my invention for A WATER WASTE PREVENTER
CISTERN FOR WATER CLOSETS to be as follows:-
The Cistern is divided into two compartments, "viz" supply, and discharge.
The supply compartment, is fed from a Ball Cock, and the water, passes through an
aperture, in the partition, into the discharge compartment.
°
The discharge compartment, is fitted with a Lever, Float, Valve, and Catches.
The Lever, is drawn down by a handle, in the usual way, and on its return, to
its former position, liberates the Float, which in rising, opens the Valve, and
allows the water, to pass through. The Valve, being held open by a loose catch,
remains in that position, until the Float, descending, as the water passes out, comes
in contact with the catch, which catch, releases the valve, and allows it to close,

page_text: I ROBERT OATES of 72 Portland Crescent, Leeds, in the County of York,
Plumber, do hereby declare the nature of my invention for WATER WASTE
PREVENTOR CISTERN FOR WATER CLOSETS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
"
The object of this Invention is to provide a cistern from which the water shall
be rapidly discharged, as required-thereby giving an effective "flush" to the
closet basin and also preventing waste of water.
To obtain this object I construct a cistern, divided into two compartments, one
for the supply of water and the other for the discharge water-The inlet of water
to the supply compartment is regulated by an ordinary "Ball cock" and the water
passes through an aperture in the partition to the discharge compartment, over
this compartment is mounted on centres a lever weighted down at one end, at the
other end is an eye for fixing a chain or other communication for drawing down
the lever, on being released the lever returns to its former position, and there
being a catch on the lever which on its return comes into contact with the end of
an arm, hung from the guide bar-under the centre of this arm a short tail hangs
down, which holds the Hoat, and prevents it rising to its normal level, but on the
arm being raised by the catch on the lever, it clears the shoulder on the float which
immediately ascends, while doing so the shoulder comes into contact with a nut on
the spindle or hollow tube of the valve, and thereby opens the valve, which is held
open by the action of a catch, until the float descends and liberates the valve-by
reversing the catch. The spindle or hollow tube acts as a guide for the valve, and
passes through the float, thereby regulating its rise and fall. The object of having
this spindle hollow is to allow air to pass down under the valve when it closes, and
thereby prevent the valve from "chucking "-this is regulated by a cap or valve-
on the top of the spindle; inside the cap is placed a piece of leather or india rubber
which rests on the top of the spindle when the valve is open-but when the valve
closes the cap or valve rests on the guide bar, and admitts air to pass down the
tube but no air passes down while the valve is open-The next change in the
condition of the cistern-by the flow of water from the supply compartment which
again raises the float until it is checked by the arm-as herein before described.
From the foregoing description it will be seen there is no possible communication
with the valve after the action of the lever has liberated the float until the cistern
has been emptied and again refilled, and thereby preventing waste of water.
In the accompanying drawings similar letters of reference indicate corresponding
parts in the several figures.
Figure 1. is a longitudinal section embodying the whole of my Invention, and
illustrates the normal condition of the cistern with the lever A. A¹ mounted over
the cistern B, the weighted end at rest, movable at the centre C, on the other end
of the lever is an eye A¹ on the lever is fixed the catch D. which acts on the
arm E., hanging on a centre, from the guide bar F. the tail E' of the arm E. holds
the shoulder G. of the float H. when liberated the float ascends and raises the

page_text: nut I. at the same time opening the valve J. which is held open by the catch K.
until the descent of the float. The valve spindle or hollow tube L. is guided in its
rise and fall by a bridge M. in the valve or service pipe N. and at the top by the
guide bar over the top of the spindle the cap or air valve O. rests on the guide
bar F. admitting air down the service pipe.
Figure 2. designates the position of the float H. and the valve held open by the
catch K. after the lever has been held down, and again released, the lever A.
returned to its former position and in doing so the catch D. raises the arm E. and
remains in that position, as indicated by this figure, until the float H. descends.
This figure also shows the air valve O. resting on the top of the spindle or hollow
tube of the valve J. and thereby preventing the admission of air to the service
pipe N.
Figure 3. designates the valve J. closed, by getting free from the catch K which
has been forced back by the descent of the float H.
Figure 4. designates an end view of the catch D. in contact with the arm E.
Figure 5. designates a plan of the arm E.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1st The application and action of a float as hereinbefore described, for the purpose
of opening or closing—or opening and closing the valve of the service pipe of the
closet basin.
2nd The general arrangement whereby no communication with or action of the
valve can take place between the ordinary flushing of the closet basin and the
refilling of the cistern.
3rd The construction, employment, and arrangement, as herein before described-
of a hollow spindle or tube for the admission of air into the service pipe-for the
purpose of preventing the "chucking" of the valve on its being closed.
