Improvements in and relating to Flushing Cisterns.
We, JAMES SHERMAN, Gentleman, and WILLIAM JAMES SHERMAN
Draughtsman both of 37 Darenth Road, Stamford Hill, in the County of Middlesex,
do hereby declare the nature of this invention to, be as follows:—
This invention relates to flushing cisterns, and consists in improved apparatus
whereby a sudden flush of a definite volume of water, may be given, by the pulling
of a chain or handle in the usual way, no further discharge of water being obtainable
until the flushing trough has again been filled for a second flush, and all waste
from the main being prevented by the locking up of the ball valve during the
complete or partial' operation of the flushing apparatus or in any circumstances
should such arise in which the flushing apparatus be imperfect in its action, or out
of gear, and further, should leakage occur in the ball tap, the overflow may be
allowed to pass down the flushing pipe to the closet or elsewhere, where it is equally
visible as from an outside overflow pipe and less inconvenient.
To carry our invention into effect we adapt an internal flushing trough to the
inside of a small tank the said trough being conveniently the half section of a circle,
and mounted on a transverse support resting on the walls of the external tank, such
support being preferably at the centre of the circle formed by the outer periphery
of the sector trough.
'
Upon the support or spindle of the sector trough, we fit an arm or quadrant arm,
outside the external tank and the said arm or quadrant is operated by a chain'or
rod connection to tilt the flushing trough from its lowest position of stability about
its central support to a perpendicular position so as to discharge its coutents
of water in a sudden flush into the bottom of the external tank from 'which a
flushing pipe without abrupt corners is led to the closet or other apparatus to be
flushed.
The ball tap from the main is affixed to the edge of the external tank so that it
discharges into the internal swinging sector trough, the governing ball of the tap
lying on the surface of the water in the said trough.
1
To the ball tap lever we attach a pivotted bridle with a central stem or pin
projecting downwards from the bridle and working in a fixed guide mounted on the.
external tank. The lower end of this bridle pin rests on an enlarged section of the
cential spindle or support of the swinging sector trough, and the said spinille or
support is provided with a hole that allows the said bridle pin and consequently 'the
ball tap lever, to fill, and open the ball tap only when the sector trough is in its
correct horizontal position to receive a further charge of flushing'water.
When therefore the flushing sector trough is in complete or partial operation, or
should it be out of gear, or be tampered with, the ball tap lever is locked in its
position, to close the tap ou the main, and no waste or constant flow of water can
thus take place.
There are no valves whatever in our apparatus to get out of order, beyond the
ordinary ball tap on the main and no water can be passed through our apparatus
except in the manner of successive flushes as hereinabove described.

We, JAMES SHERMAN, Gentleman, and WILLIAM JAMES SHERMAN,
Draughtsman, both of 37 Darenth Road, Stamford IIill, 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 :-
This invention relates to flushing cisteins, and consists in improved apparatus
whereby a sudden flush of a definite volume of water may be given with small
effort by the pulling of a bandle, no further discharge of water being obtainable
until the flushing trough has again been filled, all waste from the main supply being
prevented by the locking up of the ball valve, during the complete or partial
operation of the flushing apparatus, oi should it be in any way out of gear or
imperfect in its action; and further the overflow from the flushing tank, should
there be any, may, if desired, be allowed to pass down the flushing pipe to the
closet or elsewhere, where it is less inconvenient, than if overflowing from the
external tank, and equally visible.
Figure 1 is a longitudinal section through our apparatus complete.
Figure 2 is a transverse section thereof.
Figure 3 is a plan thereof.
Figure 4 is a detached view of the quadiant carrying the operating handle.
A is the internal flushing trough conveniently of the shape of a half sector of
a circle, mounted on a pivot or axis B resting on bearings C, in an external tank D.
The pivot or axis B is placed preferably at the centre of the circle formed by the
outer periphery of the sector flushing trough.
A quadrant or arm E is fitted at the end of the pivot or axis B outside the
external tank D, and the said arm or quadrant E is operated by a chain, or
wire, and handle G, though rod connections and a lifting handle may be equivalently
employed.
The pull of the handle and chain G serves to tilt the flushing trough A and to
discharge its contents as a sudden flush into the external tank D and thence by the
flushing pipe H to the water-closet or other apparatus.
Kis the ball tap fitted to the main supply pipe L, and to the ball lever M is
attached, by a pin N, working in a slot O in the said ball-lever, a bridle P, provided
with a central pin or stem Q. The said pin or stem Q works in a fixed guide R
attached to the external tank D, and the lower end of this piu or stem rests on an
enlarged portion S of the pivot or axis B, and thus locks up the ball tap valve
when the flushing trough is in any other position than that for filling as in Fig. 1.
In this position of the flushing tough, the pin Q coincides with a hole T in the
axis or pivot B and the ball tap lever is allowed to descend to the lowest position whilst
the flushing tough 18 then locked in position until full. The tilting movement of
the flushing trough as it returns empty to rest may be checked by a colla X on
the overflow pipe which rests on the external tank.
The overflow from the flushing trough, should there be leakage at the ball tap,
may either be permitted to overflow into the external tank and thence by the
flushing pipe H, or, if this is objected to, the overflow may be carried by the
nozzle V into a fixed overflow pipe W from the external tank.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same 18 to be performed, we declare that what we
claim 16-
1st. A flushing apparatus consisting of, in combination, a tilting trough; an axis
pivotably supporting same in an external tank, an arm on said axis, and hand

page_text: connection thereto, to tilt flushing trough; and a ball tap on main supply pipe
operated by ball lever within the flushing trough, which locks the flushing trough
and is controlled thereby, substantially as described.
2nd. In a flushing apparatus, a tilting flushing trough and means for tilting,
a supporting pivotal axis with hole therethrough, in combination with a bridle
and pin, travelling in fixed guide, and a ball tap lever pivotably attached to said
bridle, to effect the mutual interlocking of the ball tap lever and tilting trough in
various positions substantially as described.
31d. In a flushing apparatus, in combination, a tilting trough in the form of
a sector of a circle, mounted on pivotable axis at centre of circulai periphery;
means for tilting, an external tank, adapted to permit tilting of internal flushing
trough; a waste nozzle to internal trough and overflow exit in external tank
a ball tap and supply fixed to external tank and ball tap lever and ball within
Hushing trough substantially as described and illustrated herein.
