COMPLETE SPECIFICATION.
Improved Appliances for use in connection with Flushing Cisterns.
We, REUBEN COLE and FRANK COLE, of Jacob Street, Bristol, Brass-
founders, 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 :-
Our invention relates to improvements in the fittings and apparatus used in
discharging water from flushing cisterns, and consists in so arranging the various
appliances, that the lever which operates the flushing valve is made to project over
the edge of the cistern in any direction, thus enabling the wire and connections to
be attached in a more simple and direct manner than is possible with the fittings
now in general use; the counterpoise weight is also placed directly over the outlet
valve and connected therewith, thus keeping the whole of the discharging apparatus
in a compact space, and leaving ample room for the floating ball and other inlet
apparatus.
Our invention will be more fully understood by reference to the accompanying
sheet of drawings, in which
Fig. 1 is a section of a flushing cistern with the counterpoise ball in the centre
over the outlet valve.
Fig. 2 is a plan of the same showing a circular plate in which the fulcrum for
the weighted lever may be placed in either of the holes, according to the direction
in which the lever is required to project.
and
Fig. 3 shows an alternative manner of making the holes in the circular plate,
Figs. 4 and 5 are enlarged sections of the counterpoise ball, showing a taper
slot in the ball, by which the connecting rod or bar which operates the outlet valve,
passes through the ball, and is suspended by a pivot in ears at the top.
The same letters indicate the same parts in all the figures.
In carrying our invention into effect, a cistern with all the usual appliances for
supplying the water, such as self acting ball tap, air vent and overflow pipe, is
first provided, we then construct a circular plate A, with a number of perforations
therein, either a series of holes like a in Fig. 2, or curved slots like a¹ in Fig. 3,
the circular plate is attached by shoulders 6 to one side of the cistern, forming a
firm bearing for a fulcrum B which is secured by bolt and nut in either of the
holes a or in any part of either of the slots a' according to the direction in which
it is required that the lever C should project; D is a counterpoise ball at the end
of the lever C, and as the fulcrum on which the lever engages is fixed in one of the
holes in the circular plate, the ball will necessarily be near the centre, and directly
over the outlet valve; a connecting rod or bar E is attached to the valve and
passed through a tapering slot d in the ball, and is suspended by a pivotted bearing
on the top of the ball; the construction of the ball and the suspension of the
connecting rod will be more fully illustrated by the enlarged Figures 4 and 5.
The parts of our improved discharging apparatus being provided as described, it
is evident that the fulcrum may be so placed in the circular plate that the lever
will project over the side of the cistern in any required direction, and that the
counterpoise at the end of the lever will be in the centre of the circular plate, and
therefore can be placed directly over the outlet valve and operate it in a direct line,
without the intervention of a number of cranks and supplementary levers.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The construction of circular plates with shoulders for fastening them to

flushing cisterns, having a number of holes or perforations to receive a fulcrum,
which may be placed in any part of the plate, making the lever to project in any
required direction, the ball at the end of lever occupying a position directly over
the outlet valve, substantially as and for the purposes herein described, and set
forth in the accompanying drawings.
2. The construction of counterpoise balls for flushing cisterns and similar
purposes with taper slots, so that the connecting rod may operate direct on the
outlet valve, substantially as herein described and shown in the accompanying
drawings.
3. The combination of ordinary mechanism for the discharge of water from
flushing cisterns and arranging the same in a compact form, by which greater room
is left for the ordinary inlet fittings, substantially as and for the purposes herein
set forth and described.
