IMPROVEMENTS IN WATER WASTE PREVENTERS
Year: 1884

page_text: I FREDERICK THOMAS WATTS of Arch Villa, 30 Woodville Road, Cathays, Cardiff
in the County of Glamorgan, Plumber do hereby declare the nature of my said
Invention for "IMPROVEMENTS IN WATER WASTE PREVENTERS," to be as follows:-
My invention relates to improved means for regulating the supply of water to
cisterns, water-closets, urinals and other places where water is required and
preventing waste, the object of my invention being to provide an apparatus which
shall automatically cut off the flow of water as soon as the desired quantity has
been supplied or discharged. My invention consists in stopping the supply of water
after the discharge of the desired quantity by the pressure of the supply itself
within a reservoir or water-chamber in connection with the supply pipe, the said
pressure acting upon the back of a valve or valves and stopping the supply so that
the greater the pressure of the supply the more effectually is the flow stopped or
cut off at the desired time.
According to one method of carrying out my invention I provide the cock or
supply pipe with two apertures or passages for water. Between the said apertures
the passage of the pipe or cock is stopped by a solid stop, cast or formed in the said
pipe or cock, the said stop directing the flow of water through the first aperture or
passage. On the pipe or cock and around the said apertures or passages is a suitable
disc or flange having an annular or other suitably formed groove in its face the
second opening in the pipe or cock (or that leading to the outlet) opening into the
said groove or channel. To the said flange and over the said apertures I secure a
reservoir or water-chamber of any suitable size and shape, a sheet of rubber or
other suitable material being interposed between the said flange and water-chamber,
forming a valve which covers both apertures or passages in the pipe or cock. The
said reservoir or water-chamber is in constant communication with the water supply
by means of a small pipe, tube or other passage leading from the supply pipe
behind the first aperture or passage directly into the said reservoir or water-chamber.
The said reservoir or water-chamber is provided with an outlet cock, valve or other
means by which it can be readily emptied, the said cock, valve or other means being
operated by hand or by a float or by any other convenient means.

page_text: The reservoir or water-chamber being empty the water coming through the
supply pipe is directed by the above mentioned stop in the supply pipe or cock,
through the first opening thereby forcing up the valve and opening communication
with the second opening through which the water passes and flows out at the bib
or end of the pipe.
At the same time the water is flowing into the water-chamber through the small
pipe or tube above mentioned and (the outlet valve, or cock being closed) when the
said water-chamber is filled the pressure of the water therein forces the valve
down upon the passages in the supply pipe and effectually cuts off the supply and
also forces the outlet valve securely down into or upon its seat. The size and form
of the water-chamber may be varied and the passage of the water through the
small pipe or tube connecting it with the supply pipe may be regulated by a stop-
cock or other means so as to ensure any given quantity of water being discharged
at each operation.
The above described details and arrangement of my apparatus may be modified
and varied in many ways without departing from my invention.
For instance instead of the rubber valve above described any other suitable
form of valve may be employed which will effectually close the passages of the
supply pipe or cock by the pressure of the water in the water-chamber and any
suitable form of valve may be used for the outlet of the said water-chamber. The
position of the above mentioned valves and the position of the water-chamber in
relation to the supply pipe and its distance from the said pipe may also be varied.
When my invention is applied to a bib-cock the outlet valve of the water-
chamber inay open into the bib and be operated by a rod working through the said
bib. I may also admit the full supply of water to the water-chamber and connect
the said water-chamber with the bib by means of a suitable lifting valve operated
by hand or by a float or by other suitable means, the said valve, when closed, being
forced into or upon its seat and the flow of water effectually cut off by the pressure
of the supply on the back of the said valve.

page_text: through the first opening a thereby forcing up the valve or diaphragm f and
opening communication with the second opening 6 through which the water passes
and flows out at the bib i or end of the pipe. At the same time the water is
flowing through the pipe or passage g into the reservoir or water-chamber e and
(the outlet valve or cock h being closed) when the water-chamber e becomes filled
the pressure of the water therein forces the valve or diaphragm f down upon the
passages a and b effectually scaling them and cutting off the supply. The pressure
of water within the said water-chamber also forces the outlet or relief valve h
down into, or upon its seat. The diameter of the passage g determines the time
necessary to fill the reservoir e and consequently the amount of water which will
be discharged after the valve h is allowed to fall into its seat. When a further
supply of water is desired the valve h is opened. The moment this is done the
diaphragm or valve f being thus relieved from the pressure of the water within the
water-chamber e is forced up by the pressure of water beneath it in the supply
pipe, and the water continues to flow until the valve is allowed to fall into its
seat and the water-chamber e is again filled.
Figures 4 and 5 show another form of my water-waste preventer in which the
relief valve forming the outlet from the water-chamber e, is independent of the
main outlet i and the pipe g is provided with a stop-cock g¹ or other means for
the purpose of regulating and controlling the passage of water through the pipe g
so that the quantity of water discharged at each operation of the apparatus can
be varied as desired. When this form of my invention is applied to a water-closet,
the discharge from the main outlet i may be directed into and used for flushing
the pan while the discharge from the relief valve h may pass into the closet in
another direction.
Figure 6 shows another modification of my invention. In this case the full force
of the supply is received direct into the chamber e through the passage a¹. The
valve his operated by a rod, lever, push or other means, by hand or by a float, or
in any other convenient manner. The said valve being raised from its seat the
water is discharged from the bib i but on the valve being allowed to fall into its
seat the port or passage is effectually sealed by the pressure of the. water on the
back of the said valve. Any other suitable form of valve may be employed in
place of the valve h.
I do not confine myself to the above-described details and arrangement of my
apparatus as it will be readily understood that the same may be modified and
varied in many ways without departing from my invention. For instance, the
size, form and position of the water-chamber e may be varied and the said water-
éhamber may be arranged at any desired distance from the pipe or cock, it being
only necessary to increase the length of the tube or passage g and provide a suitable
pipe from the said water-chamber so as to bring the pressure of water to bear on
the back of the valve which shuts off the supply. The relief valve may also be
in a pipe at any distance from the reservoir or water-chamber e. The diaphragm
or valve f may also extend over the port or passage of the relief valve h and form
the seat for the said valve. Or instead of the rubber diaphragm f any other form
of valve may be employed which will effectually close the passage or passages of
the supply pipe or cock by the pressure exerted upon it by the water in the
reservoir e. Also any suitable form of valve or cock may be used in place of the
valve for the outlet of the water-chamber and it may be arranged in any desired
position so as to empty the said water-chamber. The positions of the ports or
apertures a and b and the valve or valves for closing them may also be varied.
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
First In a water-waste preventer, a reservoir or water-chamber e filled from
the supply pipe by means of a pipe g or other suitable connection, and provided
with a valve or other means for discharging the contents of the said water-

page_text: chamber, in combination with a suitable valve or valves in or on the supply pipe
or cock, the said valve or valves being closed and the flow or discharge of the water
cut off by the pressure upon the said valve or valves of the water within the said
water-chamber.
Second: In a water-waste preventer, a reservoir or water-chamber e filled from
the supply pipe by means of a pipe g or other suitable connection and provided
with a valve h or other means for discharging the contents of the said water-
chamber, in combination with a supply pipe or cock having passages a and b and
stop or partition c and with diaphragm or valve f constructed and operating
substantially as set forth.
Third: In a water-waste preventer, a water-chamber e receiving the full
pressure of the supply, in combination with the valve h or other suitable valve for
cutting off the flow or discharge of the water, the said valve being forced into its
seat by the pressure of the supply within the said chamber substantially as set
forth and illustrated in Figure 6.
