REGULATING THE FLOW OF WATER OR FLUID, AND IN APPARATUS USED THEREFOR."
Our Invention consists of improvements for supplying, controlling, or regulating
the flow of water in cisterns or water or fluid receptacles.
In the first place, our Invention refers to arrangements for ball valves which
close by the pressure of the water on the valve.
Secondly. To the arrangements for a valve to regulate the flow.
Thirdly. To the regulating of the flow and supply to the pan of a closet with an
after-flush when the valve is dropped.
In carrying out the first branch of our Invention we adopt mainly the following
details: The inlet for the water to the cistern is placed at the upper part thereof,
and the ball with the lever is made in the usual way, and weighted as required.
The end of the lever carrying the ball and furthest from same presses against the
lower portion of the valve (which rests upon the seat in the case of the valve in
communication with the inlet). To the upper portion of the case is secured a
screwed portion which regulates the rise of the valve; and the lever carrying the
ball is provided with a link which is attached by chain to the outlet valve on the
piston.
The action is as follows:-When the link is pulled the ball lever is lifted, and
this action also lifts the outlet valve, the inlet valve remaining shut. The water in
the cistern is thus discharged through the outlet valve. When the link is released
the outlet valve is closed and the ball drops, and by this action the inlet valve is
pressed up, and water issues into the cistern till the ball rises to its position and
closes the inlet valve.
In carrying out the second branch of our Invention we use a cistern with a
double bottom. The lower cistern is provided with a seat. On this seat, when in
position and closed, rests a valve which closes the communication with the outlet
from the cistern. The seat has on its upper end a rod which fits into an opening
(free to move) in a second rod, said second rod being provided with a valve or

page_text: washer working water-tight in a cylinder or case secured to the cistern. The
cylinder or case is perforated near its upper part.
The action of this arrangement is as follows:-The chain or other arrangement
is connected to the second rod or spindle. On this being pulled it rises in the
cylinder or case and brings the washer or valve working in same above the perfora-
tions in said case, thereby closing the communication with the first cistern. The
valve on the outlet pipe is by the same action withdrawn from its seat, and the
water in the second cistern passes through the outlet. When the valve falls it
resumes its original position on the seat of the outlet, and at the same time the valve
in the case or cylinder also falls. This latter action allows water to issue into the
second cistern to fill the same through the perforations in the cylinder.
The third branch of our Invention mainly consists of'a valve possessing similarity
of effect to the last described, but allows, when fitted to a watercloset, for an after-
flush. The valve is provided with a spindle or rod, terminating at its upper part in
a piston, working loosely in a case or cylinder.
The action of this third branch is as follows:-The case or cylinder being attached
is pulled from its seat, lifting with it the outlet valve. By the weight of the valve
pressing the water out of the cylinder or case it gradually drops on its seat again,
allowing the regulation quantity of water to pass through. After it is released the
case fills again gradually with water. This same valve may be used likewise for
the same purpose as the preceding.
We would here observe that the ball valve arrangements herein-before described
under the first part of our Invention may be used for the purpose of supply with
the link placed on the spindle, although other arrangements may be adopted if
desired.
Although we have described our Invention with regard to water, the above
description thereof will apply (mutatis mutandis) to other fluid.
