PROVISIONAL SPECIFICATION.
A Supply Valve and Water Waste Preventer Combined, for use in
Flushing Cisterns.
THOMAS CRUMP, Foreman, JOSEPH WOOD Secretary, ELLIOTT EMANUEL,
Director all of Messrs. A. Emanuel & Sons, Limited, Brass Founders, of
53 Marylebone Lane, Oxford Street, London W. do hereby declare the nature
of this invention to be as follows:-
This invention consists of a supply valve worked by a ball and lever, the inlet to
valve being controlled by a second valve placed in the body and having a spindle
with small lever projecting from side which is attached to main lever of cistern by
a shackle or other suitable method so that when the main lever is lowered it moves
the lever and spindle which being fitted with a quick thread and cap on the inside
it shuts on the seating and closes the valve during the time the lever is lowered
thus preventing any water passing through the valve.

COMPLETE SPECIFICATION.
A Supply Valve and Water Waste Preventer Combined, for use in
Flushing Cisterns.
THOMAS CRUMP, Foreman JOSEPH WOOD, Secretary, ELLIOTT EMANUEL,
Director, all of Messrs. A. Emanuel & Sons, Limited, Brass Founders of
53 Marylebone Lane, Oxford Street, London, W. 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 is an improved apparatus for preventing water-waste in cisterns
or tanks used for flushing closets and consists of a supply valve worked by a ball
and lever, the inlet being controlled by a second or check valve in such a manner
that no water shall pass into the cistern during the time it is being discharged or
emptied.
The accompanying drawings will sufficiently demonstrate the manner of
working.
Fig. (1) is a sectional elevation of cistern showing combined working parts.
Fig. (2) is a plan view of improved valve.
Fig. (3) represents a sectional plan of valve.
In Fig. (3) (A) is the body of valve containing the two seatings (B) and (C);
(D) is the inlet and (E) the outlet, (F) being an intermediate chamber which upon
the release of seating (K) conducts the water from (D) to (E). (K) is a spindle
seating which by the pressure of the spring (L) (or any other suitable means) is
kept against the valve seating (B) thus securely closing the latter until forced back
by the quick thread spindle (H), which is connected to the lever (M) and works in
the stuffing box (N). As will be seen by the drawing one end of spindle (K) is
fitted loosely into a socket in spindle (H) the other end working in a similar socket
in the screw nut (O). (P) is a piston seating connected with the ball lever (Q)
and closes on the valve seating (C) when the cistern is full. (G) is the barrel in
which (P) works.
In Fig. (1) it will be seen that the main lever (R) is attached to the rod (S)
which raises the weighted seating (T); the lower end of rod (S) passes loosely
through the top of (T) into a cavity as shown in the drawing and is fitted with an

adjustable nut (V) so that (T) is only lifted after (S): has been raised a certain
distance. In rod (S) is a slot or shackle (U) through which the lever (M)
The apparatus is so arranged that when the cistern is empty and the main
lever (R) is released both the check valve (B) and the supply valve (C) will be
open (outlet W being closed) thus allowing the water to enter the cistern, but upon
operating the lever (R) to discharge the cistern the rod (S) is raised and also the
lever (M) which causes the quick thread spindle (H) to slightly unscrew and of
course recede, thus allowing the seating (K) by the action of the spring (L) to
close the valve (B) and preventing any water passing to the supply valve (C)
which opens as the cistern becomes empty through the action of the ball lever.
On account of the play allowed by the nut (V) the seating (T) is not raised till
the valve (B) has been closed, and vice versa (B) is not opened till (T) has closed
main outlet (W). Thus effectually preventing any water passing into cistern while
main outlet is open.
Having now particularly described and ascertained the nature of our said inveu-
tion and in what manner the same is to be performed, we declare that what
we claim is:-
. 1. The action of the quick thread spindle (H) on the seating (K) thereby
opening and closing valve (B) in combination with spring (L) and lever (M)
substantially in the manner hereinbefore described.
2: The spindle (H) and lever (M) in combination with the loose action
rod (S).
3. The action of a supply valve and water-waste preventer substantially as
described in the Specification.
