County of Middlesex, do hereby declare the nature of said invention for
APPARATUS FOR PREVENTING WASTE OF WATER IN WATER CLOSETS, AND
GENERALLY APPLICABLE FOR DISCHARGING A GIVEN QUANTITY OF LIQUID FROM
TANKS, to be as follows:-
My invention has for its object to prevent the waste of water in water closets,
and is generally applicable for discharging given quantities of liquid from tanks
or cisterns.
For this purpose I place in the tank (and near the bottom of the same) a
receptacle, preferably cylindrical, and having a capacity approximately equal to
the quantity of water to be discharged at one time.
This receptacle has at the top an inlet valve below the water level of the cistern,
and at the bottom an outlet valve, connected with the inlet valve in such a manner
that, by lifting the inlet valve, the latter is caused to close. the inlet before the
outlet valve commences to open. From the top of the receptacle an outlet pipe for
air leads up above the water level of the cistern.
The inlet valve is preferably a hollow vertical cylinder open at the top and per-
forated at the side, the said cylinder being guided in a sleeve or boss extending
downward from the lid of the receptacle, and of such a length, that it overlaps and
thus closes the lateral openings of the cylinder when the latter is in its highest
position, but exposes the same, when the valve is in its lowest position.
The outlet valve is seated on a tube passing through the bottom of the receptacle
and cistern; it has on its underside a conical or ribbed extension, and at the top a
cage or frame forming a guide for the vertical spindle which connects the outlet
with the inlet valve. This spindle is hinged at the top to the bottom of the inlet
valve, and carries at the lower end a screw nut and washer or a disc adapted to
come in contact with the spindle guide formed on the outlet valve.

page_text: When the inlet valve is lifted by means of a wire, it first closes the lateral
opening through which the water has passed from the cistern and valve into the
receptacle. During this time the spindle has been allowed to slide freely in its
guide, without lifting the outlet valve. By further lifting the inlet valve, the
washer or disc of the spindle is caused to abut against the guide and lift the outlet
valve, so as to allow the contents of the receptacle to escape through the outlet
pipe. When the inlet valve is again being opened, it first allows the outlet valve
to drop on its seat and then exposes the lateral openings of the inlet valve, so as to
allow water from the cistern to flow into the receptacle.

I, CHARLES CAMPION, Plumber, of 8 Acton Street, Grays Inn Road, in the
County of Middlesex 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 has for its object to prevent the waste of water in water closets
and is generally applicable for discharging given quantities of liquid from tanks
or cisterns.
And in order that this Invention may be fully understood I will describe
the same with reference to the accompanying drawings in which Figures 1 and 2
are vertical sections through the apparatus in two different positions viz: Figure 1
shewing the inlet valve open and the outlet valve shut and Figure 2 vice versa.
For the purpose of my Invention I place in the tank or cistern A and near the
bottom of same a receptacle B preferably cylindrical and having a capacity
approximately equal to the quantity of water to be discharged at one time.
This receptacle B has at the top an inlet valve C below the water level of the
cistern A and at the bottom an outlet valve D connected with the inlet valve C in
such a manner that by lifting the inlet valve C the latter is caused to close the inlet
before the outlet valve D commences to open. From the top of the receptacle B an
outlet pipe E for air leads up above the water level of the cistern A.
The inlet valve C is preferably a bollow vertical cylinder open at the top and
peforated at the side at ee e, the said cylinder being guided in a sleeve or boss F
extending downward from the lid G of the receptacle B and of such a length, that
it overlaps and thus closes the lateral openings e e e of the cylinder C when the
latter is in its highest position but exposes the same, when the valve is in its lowest
position. To ensure the closing of the said valve C it is provided at the top with
an annular weight p.
The outlet valve D is seated on a flanged tube O passing trough the bottom of
the receptacle B and secured thereto -in any known manner. This tube O is
screwed on its lower outer end and is screwed into a nut o¹ fixed to the bottom of
the cistern, a washer o² being interposed to obtain a tight joint. The bottom of the
receptacle B slopes upwards towards the middle so that it rests on the bottom of
the sides and at the middle on the nut o¹ or it may be fixed in any other suitable
manner. The valve D has on its underside a conical or ribbed extension d, and at
the top a cage or frame f forming a guide for the vertical spindle g which connects
the outlet with the inlet valve. This spindle g is connected at the top to the
bottom of the inlet valve C by means of a ball joint h or in any other convenient
manner. The said spindle is connected to the cage f by a nut i fixed by a set
screw and washer or a disc m adapted to come in contact with the top of the cage
formed on the outlet valve D.

page_text: When the inlet valve C is lifted by means of a wire, chain, or other suitable
connection K it closes the lateral openings e e e through which the water has passed
from the cistern A and valve C into the receptacle B. During this time the
spindle g has been allowed to slide freely in its guide f for a certain distance,
without lifting the outlet valve D. By further lifting the inlet valve C the washer
or disc m of the spindle is caused to abut against the guide and lift the outlet
valve D, so as to allow the contents of the receptacle B to escape through the
outlet pipe N. When the inlet valve C is again being opened, it first allows the
outlet valve D to drop on its seat at O and then exposes the lateral openings of
the said inlet valve, so as to allow water from the cistern to flow into the-
receptacle.
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
A water waste preventer consisting mainly of a suitable receptacle placed in the
cistern and provided with an upper inlet valve having a sliding perforated part
connected to a lower outlet valve by a lost or slack motion appliance so that the
inlet valve is closed before the outlet valve begins to open substantially as described
with reference to the accompanying drawings.
