Improvements in Water-waste-preventing Cisterns for Supplying
Water-closets, Urinals, and for other analogous purposes..
I WILLIAM ECKERSLEY of 12 Barlow Lane Reddish near Stockport in the County
of Lancaster, Pattern Maker do hereby declare the nature of my said invention to be
as follows:-
The object of this invention is to ensure in flushing cisterns a given quantity of
water passing down the flushing pipe at every pull of the operating handle and to
effect the proper flushing of the water closet urinal or other apparatus without the
necessity of holding the handle.
In performing my invention 1 construct the valve which closes the mouth of the
flushing pipe in the form of a hollow copper float with a conical shaped bottom
forming a valve of large area and which is seated in an india rubber or other suitable
yielding seating.
This float valve is suspended from the usual operating lever by a rod passing
through suitable guiding sockets and which rod is provided with a projection or slot.
designed to support one arm of a bell crank lever (mounted upon a fixed centre or
axis in a bracket or pedestal) and the other arm of which bell crank carries a suitable
weight. The weighted arm aforesaid is set at such an angle that when the valve is
in its normal or closed position it exercises its influence upon the rod to keep the
valve closed but upon the valve being raised the bell crank is simultaneously caused
to turn upon its axis sufficiently far to allow the weighted arm to tilt over beyond its
centre of suspension and where it remains independently of the valve rod.
The water in the cistern is now free to escape down the open flushing pipe and so
continues escaping until by the lowering of the water in the cistern and the consequent
withdrawal of its support from the float-valve, the dead weight of the latter is so
increased as to overcome once more the weight of the bell crank and which accordingly
tilts itself back again and resumes its full effect upon the valve causing the same
to fall immediately to its seat.
In this manner and by so throwing over the weighted bell crank I ensure that the
valve shall remain open until a given quantity of water has escaped and whereby 1
obtain the full and perfect flushing action required.

COMPLETE SPECIFICATION.
Improvements in Water-waste-preventing Cisterns for Supplying
Water-closets, Urinals, and for other analogous purposes.
I, WILLIAM EOKersley of 12 Barlow Lane, Reddish near Stockport in the County
of Lancaster, Pattern Maker do hereby declare the nature of my said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to ensure in flushing cisterns a given quantity of
water passing down the flushing pipe at every pull of the operating handle and to
effect the proper flushing of the water closet, urinal or other apparatus without the
necessity of continually holding the handle.
On the accompanying drawing Fig. 1 is a side sectional elevation of a water waste-
preventing cistern with my improvements shewn applied thereto.
In performing my invention I construct the valve a which closes the mouth of the

page_text: flushing pipe b in the form of a hollow copper float with a conical shaped bottom
forming a valve of large area and which is seated in an india rubber or other suitable
yielding seating c as illustrated.
g
This conical float-valve a is suspended from the usual operating lever d by loose
connecting links e and e¹ and by a rod f the latter passing through suitable guiding
sockets and g branching from the vertical bracket or standard h. The operating
lever is provided with pins or studs e to keep the link in position. The rod fis
provided with a slot i designed to embrace one arm of the bell-crank lever k (mounted
upon a fixed stud or axis m on the before mentioned standard h) the other arm n of
which bell crank lever carries a weight 1.
It will be readily seen when the weighted arm is set at an angle as illustrated
by the valve being in its normal or closed position that it exercises its influence
upon the rod to keep the valve a closed but upon the operating handle being
pulled and the valve raised the bell crank lever is simultaneously caused to turn
upon its axis sufficiently far to allow the weighted arm to tilt over slightly beyond
its centre of suspension as indicated by dotted lines where it remains independently
of the valve rod f and the operating handle may now be let go.
The water in the cistern is now free to escape down the open flushing pipe b and
so continues escaping until by the lowering of the water in the cistern and the
consequent withdrawal of its support from the float valve, the weight of the latter
once more overcomes that of the weighted bell crank and accordingly tilts it back
again and permits it to resume its full effect upon the valve causing the same to
fall immediately to its seat again.
In this manner and by so throwing over the weighted bell crank I ensure that at
every pull of the operating lever d the float valve a shall remain open until a given
quantity of water has escaped and wherehy I obtain the full and perfect flushing
action required.
Sometimes a separate and distinct valve might be used and held up off its seat
by a ball float affixed upon the length of the rod but this I should consider to be
only a modification of my invention.
Having thus particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1st. The combination and arrangement of parts constituting my improved water
waste preventing cistern substantially as hereinbefore described and illustrated on
the accompanying drawing.
2nd. In a water waste-preventing cistern the employment of a float valve suspended
by loose links from the operating lever in conjunction with a weighted bell crank
lever adapted to hold the float valve off its seat until by the lowering of the water
in the cistern the dead weight of the float valve overcomes that of the weighted
bell crank substantially as and for the purposes herein before described and illustrated
on the accompanying drawing.
