I, MATHEW JARVIS HEIGHLEY, Edge Mount, Paddington, Liverpool, in the County
of Lancaster, do hereby declare the nature of this invention to be as follows
-
This invention relates to that class of cisterns known as syphon flushing cisterns in
which water is stored for flushing purposes and from which a given quantity of water
is required to flow each time that the How is started.
It consists essentially in forming the syphon by means of a bell preferably conical
provided with one or more pipes fitting over a stand pipe the outer surface of which
corresponds in contour with the bell so that a downward motion of the bell forces the
water upward to the mouth of the stand pipe thereby completing the syphon through
the side pipe or pipes.
In carrying out the invention the walls of the cistern may be constructed in the
usual way, and a stand pipe or outlet pipe cast or otherwise fitted therein. This may
be of any suitable height for the situation where it is to be placed but it is preferable
that it should rise above the sides of the walls of the cistern so that the water cannot
rise sufficiently high to trickle over.
Over the stand pipe is placed a bell preferably conical in shape closed at the top,
and open at the bottom. Around the stand pipe is placed a wall or abutment corre-
sponding in contour to the interior of the bell against which the bell may closely fit.
The conical shape of the bell and the abutment allows for an increasing space between
At or near
the two, as the former is raised and a decreasing space as it is lowered.
the top of the bell are placed one, two or more pipes which project downward towards
the bottom of the cistern. Round the base of the stand pipe is formed a chamber
into which the mouth of the bell enters. This chamber may be formed by a wall or
partition raised in the cistern or by recessing or dishing it in the bottom or by any
other means found convenient. The lever for actuating the bell is attached to it at
the top or other suitable position. When it is intended that the flushing should be
done periodically the bell is furnished with a small tank cast or fitted round it which

page_text: fills with water when the cistern is full, the weight of which causes the bell to fall and
discharge the cistern. The bell is prevented rising above a certain height by a cover
on the cistern, or other stop suitably placed. A small syphon is placed in this tank
which empties it and allows the bell to rise again into its normal position.
In action the movement of the bell which forces the water contained between it
and the standpipe ; and that contained in chamber at its base, is forced upwards, and a
syphon formed by means of the side pipe or pipes through which the water from the
cistern flows.

page_text: I, MATHEW JARVIS HEIGHLEY, Edge Mount, Paddington, Liverpool, in the County
of Lancaster, 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 that class of cisterns known as syphon flushing cisterns in
which water is stored for flushing purposes, and from which a given quantity of
water is required to flow each time that the flow is started.
It consists essentially in forming the syphon by means of a bell, preferably conical,
provided with one or more pipes fitting over a stand pipe, the outer surface of which
corresponds in contour with the bell so that a downward motion of the bell forces the
water upward to the mouth of the stand pipe, thereby completing the syphon through
the side pipe or pipes.
The invention is best described by aid of the accompanying drawings in which—
Figure 1 is a sectional elevation.
Figure 2 is a plan.
Figure 3 is a sectional elevation shewing the improved syphon provided with two
feed pipes.
In these A is the cistern of any convenient form. B, the stand pipe or outlet
pipe, cast or otherwise fitted therein. This may be of any suitable height for the
situation where it is to be placed, but it is preferable that it should rise above the
sides of the walls of the cistern so that the water cannot rise sufficiently high to
trickle over.
Over the stand pipe B is placed a bell C, preferably conical in shape closed at the
top and open at the bottom. Around the stand pipe B is placed a wall or abutment D
corresponding in contour to the interior of the bell C against which the bell may
closely fit. The conical shape of the bell C and the abutment D allows for an
increasing space between the two, as the former is raised and a decreasing space as it
is lowered. At or near the top of the bell is placed a feed pipe E which projects
downward towards the bottom of the cistern A. If desired two or more feed pipes
may be provided as for instance E, E, Figure 3. Round the base of the stand pipe B
is formed a chamber F into which the mouth of the bell enters. This chamber F
may be formed by a wall or partition G (Figure 3) raised in the cistern, or by recess-
ing or dishing it in the bottom (Figure 1), or by any other means found convenient.
The lever H for actuating the bell C is attached to it at the top or in other suitable
position. In the drawing the lever is shown pivoted at I and attached to the bell by
the pins J, the end of the lever being bent for the attachment of the hand pull at K.
At or near the top of the bell, an air pipe L may be provided if desired. If two or
more feed pipes E are provided this air pipe is generally not found necessary.
In action, the movement of the bell to the position shown by the dotted lines,
forces upward the water contained between it and the wall or abutment D of the stand

page_text: pipe, and also the water contained in the chamber G. A syphon is thus formed by
means of the feed pipe or pipes E, through which the water from the cistern flows;
the air contained in the space at the upper part of the bell being driven out (when
the bell is caused to descend) through the air pipe L or in the arrangement shown
in Figure 3 by the feed pipes E. When it is intended that the flushing should be
done periodically the bell is furnished with a small tank cast or fitted round it, which
fills with water when the cistern is full, the weight of which causes the bell to fall and
discharge the cistern. The bell is prevented rising above a certain height by a cover
on the cistern; or other stop suitably placed. A small syphon is placed in this tank
which empties it and allows the bell to rise again into its normal position.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. In a flushing apparatus, a bell shaped syphon surrounding the stand pipe,
movable vertically in a chamber or cavity in the cistern at its lower extremity, and
connected with the hand pull so that as the said syphon is lowered, the fluid contained
in the chamber below it and between the stand pipe is forced to flow into the stand
pipe, thus completing the syphon, the whole arranged substantially as described.
2. In combination with the bell shaped syphon, having an outer wall C, movable
vertically, and an inner wall or abutment D, of the feed pipe or pipes E, air pipe L
and chamber or cavity F of the cistern, substantially as and for the purpose
described.
3. The modification of my flushing apparatus (whereby it is made applicable for
automatic flushing at regular intervals), substantially as described.
