PROVISIONAL SPECIFICATION.
Improvements in connection with Water Waste Preventers.
JAMES KELLETT OLDFIELD 199 Dawes Road Fulham London Builder do
hereby declare the nature of this invention to be as follows:
__
The improvements I claim are, that I make my cistern perpendicular, it resembles
a short length of a rain water down pipe, (either square or round) with ears on top
and bottom ends for fixing to wall, and a rim round bottom end, to allow for
tapping for screws to fasten bottom end on.
Through centre of bottom I have a spindle valve, tapped and screwed through
the bottom, the screw sufficiently long to attach iron socket, and iron pipe for
flushing purposes.
The spindle to go up through the cistern and stand above top
end. The top end to be screwed for attachments for opening valve by pulling
down lever.
I fix my water supply valve at top end of cistern, but I dispense with usual
floating ball; instead of which ball I have a loose air tight float floating up and
down the inside of cistern with the water, with tube through centre for the valve
spindle to work, the said tube projecting inch under float for releasing struts as I
explained farther on.
I attach the spindle to valve at bottom by screwing right through the weight of
valve, and I have the thread of screw carried four inches up the spindle inside
cistern for the following reason.
I have two struts, one on each side of valve, the bottom end of struts working
on a pin through a coller fixed on bottom of cistern, the top end of the struts,
falling on to and clipping the spindle in the form of half a nut tapped through to
fit thread on spindle, and meeting opposite each other, and hy this means holding
up the valve, when the lever is pulled, and as the water runs out and the float drops
down, the projecting tube under float, opens out the struts and allows the valve
to shut.
I have also a tube with one end stopped under the valve, which acts as a guide
for spindle, and being full of water lowers down the valve slowly, allowing time for
the cistern to empty itself of water.
Also where the water supply is direct from main to cistern, I fix my supply
through bottom of cistern, opening and shutting by means of an upright rod, with
india rubber washer on bottom end, running through tube fixed in float, to top end of
cistern, the top end of rod connected to lever inside eistern working on pivot, and
as the cistern fills with water, float rises and lifts long end of lever, tightens down
the rod on the valve, and shuts of the water.
I also fix on top of one strut a small bar working through a loop hole on top of
opposite strut to ensure keeping them in position and true with the spindle..
Has will be seen the float answers two purposes, it shuts off the water in rising
and releases the struts and allows the valve to drop down, when lowering.

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 a new type of water waste preventers, in it being
vertical and intended to stand level with the seat of the water closet.
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended an explanatory
sheet of drawings in which :-
Figure 1. is an elevation showing my internal arrangements of said water waste
preventer.
The method I use in shutting off the water when cistern is full, is done by a
float (A.) which, as the water rises in the cistern, lifts up the float, and the float,
lifts up a lever working in a slot, fixed to the side of the cistern, which, I mark (B)
and, in rising it lifts the ball valve lever marked (C) and shuts off the water when
cistern is full. I also have fixed to lever (B) a rod marked (D) which rides on
lever (E) which acts, to also shut off water before the outlet valve at bottom of
cistern is moved by pulling down outside lever (E) and when the bottom outlet
valve is open keeps the water shut off till it is allowed to drop. This relates to
top part of cistern.
When the lever (E) is pulled for flushing it lifts up the spindle connected to
valve, and I have two struts or catches working opposite one another marked (F)
which works on pivots and falls on the spindle and I notch the spindle and as it
is lifted the catches hold it up till the float drops down and releases it, by means of
a wedge shaped barrel projecting from bottom of float for that purpose.
I also have a lever (G) working on pivot on each catch, so that the float releases
the spindle by their action as well as the wedge.
The cup marked (H) is a fixture to the bottom, so that the valve stop is pulled
up into it, to protect the pressure on stop when water is rushing out.
All the bottom mechanism is fixed on a loose metal plate, which, with hole in
centre fits over end of valve and allows all to be taken out at one time, through the
top end of cistern.
Figure 2. is an elevation showing internal arrangements as fitted with syphon for
emptying purposes but with all the same fittings for shutting off the water as shewn
in Fig. 1.
Fig. 3 shows the plan of the mechanical arrangements at the bottom of the
cistern, (Fig. 1) the letters marked in Fig. 3 corresponding to those marked in
Fig. 1.
Having now described the nature of my invention I declare that what I
claim is :-
That it is absolutely a water waste preventer, and is practically noiseless in
action, that it is easy to fix, and costs less both in material and labour in fixing.
And the manner by which I fix and release the spindle valve and also the manner
by which I shut off the water when full in a confined space by double acting levers,
fittings, constructed and acting in the manner herein described in reference to and
shown in the accompanying drawings.
Dated this Twenty-seventh day of May 1896.
