PROVISIONAL SPECIFICATION.
An Improved Water Waste Preventer.
I WILLIAM HENRY JONES of 10 Pennsbury Terrace, Wandsworth Road in
County of Surrey, Builder, do hereby declare the nature of this invention to be as
follows:
:-
My invention relates to an improved water waste preventer which unlike those
generally used stands normally empty and is only filled at the time of use.
The ball valve by which the waste preventer tank is supplied differs from others
in that the valve (which is spherical and closes upon a corresponding spherical
socket) closes with instead of against the flow, the pressure of the water acting
conjointly with the weight of the float to close the valve, the valve being opened
by a positive motion imparted to it by the mechanism hereafter described, the
buoyant power of the float being only used to release it from said mechanism in order
to permit the discharge valve to be opened as hereafter described at the same
time that the ball valve is closed.
The invention consists in the combination with a ball valve so acting, of a
rocking axis to which are connected the pull handle and the discharge valve in
such manner that when the former is pulled the latter is lowered on to its seat,
said axis having an arm which acts on the ball lever in such manner as to raise the
latter and open the supply valve at same time that the discharge valve is closed as
above mentioned, said arm engaging with the ball lever which acts as a detent to
retain the valves in the positions mentioned whilst the tank is filling. As soon as
the water rises to the level of the ball float the ball lever becomes disengaged from
the said arm which is then permitted to fall by its own weight whereby the axis is
rotated in the opposite direction so as to cause the discharge valve to be raised
from its seat, the arm acting also to carry said valve away from above its seat to
prevent liability of the valve being prematurely closed by the suction of the
discharge pipe.

COMPLETE SPECIFICATION.
An Improved Water Waste Preventer.
I WILLIAM HENRY JONES of 10 Pennsbury Terrace, Wandsworth Road, in
the County of Surrey, Builder 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 :-
The
My invention relates to an improved water waste preventer which, unlike those
generally used, stands normally empty and is only filled at the time of use.
ball valve by which the waste preventer tank is supplied differs from others in that
the valve (which is spherical and closes upon a corresponding spherical seat) is
closed instead of being opened by the fall of the ball float, the valve closing with
the flow of the water from the tank so that the pressure of the water to the tank
assists, instead of opposes, the closure of the valve by the weight of the float, the
said supply valve being opened by a positive motion imparted to it concurrently
with the closing of the discharge valve, and the buoyant power of the float serving
only the purpose of effecting the disengagement of the float in order to permit it to

as hereafter described.
Reference is to be had to the accompanying drawings forming part of this
Specification, wherein
Figure 1 shows a side elevation, Figure 2 an end elevation and Figure 3 a plan
of the mechanism of the waste preventer.
The same letters of reference indicate like parts in all the figures.
This mechanism comprises the combination, with the float lever A operating the
supply valve B in the manner described, of a rock shaft C to which are connected
the pull handle D and the discharge valve E in such manner that when the former
is operated the shaft is rocked, the discharge valve is lowered and closes the outlet
from the tank, said shaft C having an arm F which (when the shaft is rocked by
operating the pull handle as above mentioned) raises the ball lever A and thus
opens the supply valve and closes the discharge valve at the same operation. The
arm F acts as a weight to rotate the shaft in the opposite direction to that in
which it was moved by the pull handle but is prevented from so acting until the
tank G is filled, by engaging with a nib a on lever A whereby the lever A and
arm F mutually retain and support each other in the position shewn in dotted lines
in Figure 1, thereby keeping valve B open and valve E closed. As soon as the
water rises high enough to float the ball, the lever A becomes raised and disengaged
from the arm F which falls by its own weight and rotates the shaft C so as to
cause the valve E to be opened at same time that valve B is closed by the fall of
lever A. The pull handle is connected by a chain or equivalent connection with
an arm c on the shaft C and the valve E is raised and lowered by a chain e
attached to said arm c and winding partly on the shaft C. The valve E is a
spherical faced valve fitting in a corresponding spherical seat without washer..
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―
1st. The herein described water-waste preventer consisting in the combination,
with a valve opened by the rise, and closed by the fall, of the float, of mechanism,
substantially as described, operated in one direction by the pull handle and in the
other by gravity, said mechanism being adapted to raise and hold up the ball lever
and to be itself retained by said lever until released by the floating of the ball
lever, and of a discharge valve operated by said mechanism, all substantially as and
for the purpose specified.
2nd. In a water-waste preventer which stands normally empty and is filled when
the flush is required, the combination, with a float valve closing by the fall of its
float arm, of a rock shaft having an arm adapted when operated by the pull handle
to raise and engage with the float arm, as described, and of a discharge valve
opened by the reverse motion of the rock shaft when the supply valve float is
permitted to fall, substantially as specified.
