PROVISIONAL SPECIFICATION.
Improvements in Syphon Flushing Cisterns.
I, HERBERT EDWARD BRICE, of Alexandra Road, Edgbaston, in the City of
Birmingham, Brassfounder, do hereby declare the nature of this invention to be
as follows:-
This invention relates to syphon flushing cisterns and water waste preventers,
and has for its object, a simple and efficient means of flushing, combined with
fewness of parts without any liability of the assemblage of parts becoming deranged.
In carrying out my improvements, I take an ordinary flush box or cistern,
preferably with a well formed in the bottom of the same, from the middle of
which the fixed stand pipe, which is flared at its upper end and extends a little
above the top edge of the sides of the flush box, is directed. The said standpipe
is passed through the bottom of the well and is there secured thereto by the
usual lock-nut and is connected to the downpipe by an ordinary tail piece and
union.
Covering and working over the standpipe is a bell or cylinder, closed at the
top and open at the bottom and having trunnions arranged upon the two opposite
sides near its upper ends for the picking up of the same by the branched ends of
a bifurcated lever turning upon a pin supported by a bracket carried by the end
of the flush box.
The lower end of this bell, which is preferably enlarged in diameter to fit
loosely into the well, is closed by a pierced cap or plate, with a neck, gland or
sleeve passing up its middle and having an inside diameter suitable for working
freely upon the outside of the stand pipe. Encircling and working freely upon the
neck, which has a stop flange at its upper end is a rising and falling valve or
plate adapted to rise from or cover up the piercings in the bottom plate or cap
of the bell on the same being raised or lowered.
Thus the neck or sleeve, which works on the standpipe and is carried by the
closed bottom or cap of the bell, is possibly about an inch or so long, thus leaving
the upper and body part of the well perfectly open, so that when the lever of the
cistern is pulled, the bell or cylinder, with its entrapped column of water, is
bodily lifted and the level of the said column is taken or raised above the plane
of the mouth of the standpipe down which the water rushes and starts the syphonic
action.
OPERATION.
The normal position of the bell is lowered. Assuming then, that the cistern,
which is fitted with the usual ball-valve and overflow, to be full, on the lever being
pulled the bell is raised and the weight of the colunin of water therein forces the
valve home to its seating and closes the openings in the bottom plate, thereby:
entrapping the said column, which is bodily and continuously lifted above the level
of the upper end of the standpipe hence the syphonic action is started, and on the
lever being released and the syphonic pull of the liquid coming into effect, the
bell falls and the upward pressure of the water in the tank forces the valve up."
The said valve has clearances to admit of the flowing of the liquid through the
pierced bottom plate of the well and so long as the upward flow of water con-
tinues so long will the valve he held up and immediately the said flow ceases,
then the valve falls..

page_text: The bottom plate or the bottom of the well may be provided with lifts for
preventing the said plate and well bottom coming together.
Instead of the bell being picked up directly by the branched ends of the lever
taking hold of trunnion ends, the said bell which contains a column of water may
be picked up by the valve through the medium of rods hanging from the lover.
The valve in this case comes underneath the pierced bottom of the bell and may
be faced with rubber and the gland or neck which works over the standpipe may
be packed or stuffed.

Improvements in Syphon Flushing Cisterns.
I, HERBERT EDWARD BRICE, of Alexandria Road, Edgbaston, in the City of
Birmingham, Brassfounder, 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 syphon flushing cisterns and water waste preventers,
and has for its object, a simple and efficient means of flushing, combined with
fewness of parts without any liability of the assemblage of parts becoming deranged.
In carrying out my improvements, I take an ordinary flush box or cistern
preferably with a well formed in the bottom of the same, from the middle of which
the fixed stand pipe, which is flared at its upper end and extends a little above the
top edge of the sides of the flush box, is lirected. The said standpipe is passed
through the bottom of the well and is secured thereto by the usual lock-nut and
is connected to the downpipe by an ordinary tail piece and union.
Covering and working over the standpipe is a bell or cylinder, closed at the top
and open at the bottom and having trunnions arranged upon the two opposite sides
near its upper ends for the picking up of the same by the branched ends of a
bifurcated lever turning upon a pin supported by a bracket carried by the end of the
flush box.
The lower end of this bell which is preferably enlarged in diameter to fit loosely
into the well, is closed by a pierced cap or plate, with a neck, gland or sleeve passing
up its middle and having an inside diameter suitable for working freely upon the
outside of the standpipe. Encircling and working freely upon the neck, which has a
stop flange at its upper end is an unpierced rising and falling valve or plate adapted
to rise from or cover up the piercings in the bottom plate or cap of the bell on the
same being raised or lowered.
Thus the neck or sleeve, which works on the standpipe and is carried by the closed
bottom or cap of the bell, is possibly about an inch or so long, thus leaving the
upper and body part of the well perfectly open, so that when the lever of the cistern
is pulled, the bell or cylinder, with its entrapped column of water, is bodily lifted
and the level of the said column is taken or raised above the plane of the mouth of
the standpipe down which the water rushes and starts the syphon action.
Figure 1 of the accompanying drawings represents in longitudinal vertical section
of a direct-starting syphon flushing cistern constructed according to my invention.
This view shows the parts in their normal position, with the bell down and filled with
water.
Figure 2 represents a like view as Figure 1, but with the bell and column of water
within lifted above the mouth of the standpipe, and showing the valve closing the
inlet openings in the hell

page_text: Figure 3 is a topside plan of Figure 1, and Figure 5 is an underside plan of the
bell showing the piercing.
Figure 4 is a vertical section of the bell separately.
Figure 6 is a plan of the closed valve or plate.
The same letters of reference indicate corresponding parts in the several figures of
the drawings.
a is a flush box, having a well a', in the bottom of the same and fitted with a
standpipe b, having a funnel-shaped top b', and being located within a bell or
elongated and inverted cup-shaped vessel c, picked up through trunnions c¹, by the
branches d', of a lever d, fulcramed at d. The bottom c, of the bell c, is pierced
with holes c, and has a neck c, adapted to slide freely over the standpipe b, and-a
valve stop, and under collar c. e is a plate valve, which is raised on the bell
falling, by the under pressure of water coming against it, and falls and closes the
openings c³, when the bell is raised, through the pressure of the column of water
above it.

OPERATION.
The normal position of the bell is lowered. Assuming then, that the cistern, which
is fitted with the usual ball-valve and overflow, he full; on the lever being pulled the
bell is raised and the weight of the column of water therein forces the valve home to
its seating and closes the openings in the bottom plate, thereby entrapping the said
column, which is bodily and continuously lifted above the level of the upper end of
the standpipe, hence the syphonic action is started, and on the lever being released
and the syphonic pull of the liquid coming into effect, the bell falls and the upward
pressure of the water in the tank forces the valve up. The said valve has clearances
to admit of the flowing of the liquid through the pierced bottom plate of the well and
so long as the upward flow of water continues so long will the valve be held up and
immediately the said flow ceases, then the valve falls.
The bottom plate (or the bottom of the well) may be provided with lifts for
preventing the said plate and well bottom coming together.
Instead of the bell being picked up directly by the branched ends of the lever
taking hold of trunnion ends, the said bell which contains a column of water, may be
picked up by the valve through the medium of rods hanging from the lever. The
valve in this case couies underneath the pierced bottom of the bell and may be faced
with rubber and the gland or neck which works over the standpipe may be packed
or stuffed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
First. The means for starting syphon flushing cisterns, consisting of a closed bell
with a pierced bottom working over the standpipe and having a rising and falling
plate valve or equivalent located within and at the bottom of it, substantially as
described and set forth.
Secondly. In syphon flushing cisterns, the general construction, arrangement
and combination of the parts, substantially as and for the purpose described and set
forth.
