I WILLIAM WRIGHT of Number 2 Saltash Street Plymouth in the County of Devon
Brass-founder and Finisher do hereby declare the nature of my invention for
A REGULATING WATER WASTE PREVENTOR to be as follows:-
A Cistern made of Iron, or any other suitable material, with a Balance Valve for
the supply of Water to the Cistern. I attach a Float to the Lever of the Balance
Valve with a Spill, or Chain passing through the Float with a Nut or, any other
suitable means on the Spill. As the Water rises in the Cistern, the Float closes the
supply Valve when sufficient Water is in the Cistern. The Nut is to regulate the
height of the Float which is attached to the Lever of the Balance Valve. I attach by
suitable means, another Lever, to the Lever of the Balance Valve, one end attached to
the Float, the other end attached to a Crank or Chain. I have an ordinary Syphon in
the Cistern, so that when the Chain is pulled down it closes the Supply Valve, and the
extra Lever acts the reverse way, by pulling down the Float; thereby causing the
Water to rise to the Syphon, and, thereby causing a Flush of Water, and no supply
can take place in the Cistern until the Chain is released.
Dated this Sixteenth day of September 1886.

page_text: I WILLIAM WRIGHT of 2 Saltash Street Plymouth in the County of Devon Brass
founder and finisher 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 :-
My invention relates to apparatus for supplying regulated quantities of water (for
the purpose of flushing water-closets) and preventing waste.
The apparatus is of that kind in which the contents of a cistern are discharged at
required times, through an intermittent syphon; and the invention consists in the
combination with the inlet valve of a float and of a system of levers and connections
whereby the buoyant power of the float is caused to act on and close the valve and
whereby the float may be immersed beyond its normal line of flotation, in order by
its extra displacement, to cause the water level to rise in the cistern sufficiently to
start the syphon; the arrangement being such that so long as the float is immersed
to, or beyond its normal extent, the valve will be kept closed. To prevent waste by
the temporary rise of the water level in the cistern, means are combined with the fore-
going, for temporarily closing the overflow warning pipe, which, for the purpose of
giving notice of any irregularity of working is necessarily connected to the cistern at
a point below the level to which the water must rise, in order to fill and start the
syphon.
Reference is to be had to the accompanying drawings forming part of this
specification, wherein figure 1 is a longitudinal section through the cistern provided
with the apparatus of my invention. Figure 2 is a cross-section taken just within the
right hand end of the cistern. Figure 3 is a half plan, with the cover removed. The
same letters of reference indicate the same parts in all the figures.
A, B, and C are the connections of the inlet, discharge, and overflow pipes,
respectively. a is the inlet valve fitted in the bottom of the cistern, and b is the
intermittent syphon-tube placed within the cistern and communicating with the
discharge pipe B. D is the float and E the pull-handle by which it is operated.
The inlet valve a opens under the pressure of the water supply, and is closed
when the cistern is sufficiently full, by the buoyant power of the float D acting on
it through the medium of a rod d or other connection, attached to one end of a
lever A of the first order pivoted at f to the long arm of another lever G fulcrumed
at g to a fixed support and bearing by its short arm upon the valve and pressing it on
to its seat. The other arm of the lever Fis connected by a rod e or other connection,
with one arm of a lever e¹ to whose other arm is attached the pull handle E. c is
a valve carried by the weighted end of a lever c¹ and adapted to close against a seat c³
on the mouth of the overflow pipe when released by pulling the handle E for the
purpose of immersing the float and discharging the contents of the cistern. The lever c¹
is fulcrumed on a fixed support, and its other arm is acted on by an arm c² projecting
from the rod e so that on the release of the handle E and the descent of the rod e
consequent on its own weight, assisted by the buoyant power of the float, the arm c³
The connection of the
depresses the tail end of the lever c¹ and opens the valve c.
rod d is adjustable by means of a nut or other device d¹ above the float, to regulate

page_text: the height to which the float can rise in the cistern and the rod passes freely through a
tubular socket, traversing the float from top to bottom, so that the rod can rise
independently of the float, in order that the valve may be relieved of the weight of
the float whilst the cistern is being filled. The descent of the float is limited by
ledges h projecting from the sides of the cistern on which the float remains seated,
after the handle E is released until the water rises again to a sufficient height to
float it.
The operation is as follows;-Supposing the cistern to be filled to the normal height
―i.e. the level of the overflow pipe on pulling the handle E the rod e will be drawn
upwards and the float will be drawn downwards and so immersed more deeply, its
extra displacement raising the water level in the cistern sufficiently to fill the bend of
the syphon band so start it, at the same time that the arm ² no longer acting on the
lever c', will allow the valve c to close the overflow C. Thereupon, the syphon which
is of relatively large capacity will quickly empty the cistern, and as soon as the water
level falls below the mouth of its short limb, its action will be arrested. The act of
pulling on the handle E imparts an upward strain to the fulcrum of the lever F
whereby the lever G is caused to press on and close the valve a and the descent of the
float, and consequently the extent of notion of the pull handle E being limited by
the stops h, it follows that so long as the handle is pulled, the valve a will be kept.
closed, and no further supply can be obtained. The syphon continues to discharge
the contents of the cistern after the handle E is released (if it be not already emptied
when the handle is released) and upon the action of the syphon being arrested by the
unsealing of its shorter limb, as above mentioned, the cistern immediately refills, by
the opening of the valve a which occurs when the handle is released and the float is
not waterborne. Upon the float being again waterborne and raised to its normal
height, it raises the rod d and through the lever F causes the lever G to press on and
close the valve, the descent of the rode beyond a certain point being limited by
a stop.
The opening of the valve a may sometimes occur a little before the cessation of the
syphon's action, but this is of little moment, as the discharging capacity of the syphon
is considerably greater than the inlet capacity of the valve orifice, and the slight delay
which may be thereby caused in the arrest of the syphon is consequently immaterial.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is-
1. In a cistern provided with an intermittent discharging syphon, the combination
with the inlet valve, of a float and of means substantially as herein specified whereby
the buoyancy of the float is caused to close the valve, and whereby the act of
depressing the float for the purpose of starting the syphon is made to keep the valve
closed so long as the float is depressed, substantially as described and represented in
the drawing.
2. The combination in an apparatus for supplying regulated quantities of water to
closets and preventing waste, of an intermittent syphon, a float connected with and
acting on the inlet valve in the manner and for the purpose herein described, means
of depressing the float and thereby raising the water level, in order to start the syphon,
and means of temporarily closing the overflow whilst the float is so depressed,
substantially as specified.
