Improvements in Syphon-flushing Cisterns.
I, JOB DEELEY of Phoenix Works, Holloway Head in the City of Birmingham,
Plumbers' Brass Founder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to syphon flushing cisterns, and is an improvement upon
Letters Patent granted to me on the 19th day of February 1884, No. 3546, and also
upon an application for Letters Patent made by me on the 16th day of January 1889,
No. 804.
My invention has for its object, the production of a perfect water-waste preventer,
combined with a noiseless flusher.
The invention consists essentially of a long and short leg syphon arrangement, with
the short leg or inlet passage pierced near its upper end, over which a flexible sleeve-
valve carried by a sliding tube, comes, when the said tube is raised by a float connected
at its lower end.
The long leg or outlet of the syphon arrangement, has an open-topped branch,
which is closed by a self-closing valve, operated by the lever of the cistern-pull, and
by the rising of which said valve, water for creating the vacuum, is allowed to pass
into the long leg and downpipe of the said syphon.
In carrying out my invention, I proceed as follows-
I dispose within the inside of a cistern, commonly called a flush box, an upright
two-legged syphon, the long leg of which I will call the stand-pipe, and the short leg
I will call the inlet pipe.
The bend connecting the inlet pipe to the stand-pipe, extends above the top of the
flush-box, whilst the lower open end of the inlet comes within a short distance of the
flush-box bottom.
Surrounding the inlet pipe, is a freely sliding tube, with a hemispherical or other
float at its lower end, and with its top end provided with a flexible sleeve-valve which
is brought over, and removed from holes or piercings made through the said inlet
pipe at its junction with the connecting bend; so that on the "breaking of the
vacuum "when flushing, these holes are uncovered, by the falling of the float, conse-
quent upon the removal of nearly the whole of the water upon the flush-box, by the
syphon drawing action.
By thus admitting air into the syphon arrangement, at the time when the last
portion of water is being drawn from the flush box, gurgling is prevented, and a
noiseless flusher produced.
Instead of the sleeve-valve for the covering and uncovering of the holes being
carried by a tube with an independent float at its bottom, it may be operated by
the ball-cock stem employed for regulating the admission of water to the cistern,
after each flush.
The stand-pipe lower end at its junction with the down pipe which leads to the
closet, has an angle arm or bend, with an open top, and through which, water from the
cistern first flows for creating a flush.
Disposed above the bend, is a chambered valve, which when in its normal position,
has its enclosed bottom, which is faced with rubber or other yielding material, resting
over and upon the open mouth of the supplementary water-inlet branch as aforesaid,
so as to close it. This chambered valve has a pierced disc or diaphragm working
freely within it, and with the piston rod passing, and working freely through a hole
in the middle of the valve, and which rod upper end is connected to the inner directed
end of the pull lever, whose outer end is provided with a pull chain.
Linon the top face of the niston valve, and above the piercings thereof, is an

page_text: unpierced disc, which when the piston moves upwards within its valve, the disc closes
the piercings, but on the piston moving in the reverse direction, the disc lies before
the piercings, and allows water to pass between itself and the piston.
The underside of the valve has pronged leads, which conduct the valve centrally
upon the open mouth of the branch inlet.
Assuming that the flush-box is full, the pulling of the chain-pull, lifts the lever, and
raises the piston and valve together, and allows water to flow momentarily through
the branch inlet into the stand-pipe and down-pipe, which thus creates a vacuum in
the syphon system, and causes water to flow up the inlet pipe, over the bend and
down the stand-pipe, to the downpipe, thereby flushing a closet; and on the water in
the cistern becoming exhausted from the said flush-box, the float falls, carrying with
it the sleeve-valve, which opens the air inlets, and prevents noise.
.
The valve of the inlet bend remains suspended, until a vacuum in the syphon is
created, when it then descends, and closes the inlet to the said branch.
It will be understood that water passes into the interior of the valve, and by its
passage outwardly, through the hole in its crown, forms the means whereby the
said valve is made to act automatically for the closing of the entrance to the
branch.
The sleeve-valve carried by the float, is limited by a stop; and on the rubber
coming before the piercings of the inlet pipe, the same are closed.
The piston of the self-closing valve is made to take a return position, on the pull-
chain being released.

Improvements in Syphon-flushing Cisterns.
I, JOB DEELEY, of Phoenix Works, Holloway Head, in the City of Birmingham,
Plumbers' Brass Founder, 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 Blushing cisterns as hereinafter described and is an
improvement upon Letters Patent granted to me on the 19th day of February 1884,
No. 3546, and also upon an application for Letters Patent made by me on the 16th day
of January 1889, No. 804.
My invention has for its object, the production of a noiseless flusher, combined
with a water-waste preventer.
The invention consists essentially of a stand-pipe, with a depending branch or short
leg, whose upper part, viz., at its junction with the stand pipe, is pierced with a small
hole or holes, over which a flexible sleeve, called hereinafter the silent valve, passes,
when a float at its lower end, or a sliding tube directed from it, rises, on the flush
box or cistern filling.
The stand pipe lower end, has an open topped branch, which is normally closed by.
a self acting valve, operated by the cistern pull.
The rising of the said valve, from its seat, uncovers the open top of the branch,
and allows water to flow through and down the base of the stand pipe, and
from thence down the down pipe, whereby a partial vacuum is created, and the
flushing started.
In carrying out my invention, I proceed as follows.
I dispose within the inside of a cistern, commonly called a flush box, an upright
stand pipe, with a depending branch or leg coming within a short distance of the flush
box bottom, and at the upper part of the said branch or leg, a sleeve and sliding
valve is disposed, by the removal of which from before or in front of, holes or

page_text: piercings, gurgling at the termination of the flush, is prevented and a noiseless, or
nearly noiseless, flusher produced.
The sleeve valve, is carried by a float, working preferably on the branch or leg,
although the said valve, may be controlled or operated, by the ball valve, or its
stem.
The stand pipe lower end, at its junction with the downpipe, which leads to the
closet, has an angle arm or bend, with an open top, and through which water from
the cistern, first flows for creating a flush.
Disposed above the bend, is a chambered valve, which when in its normal position,
has its enclosed bottom, which is faced with rubber or other yielding material,
resting over and upon the open mouth of the supplementary water-inlet branch, as
aforesaid, so as to close it.
This chambered valve, has a plain disc or diaphragm working piston like and freely
within it, and with the piston rod of it, passing and working through its crown, and
which rod upper end, is attachedly connected to the inner directed end of the pull
lever, whose outer end is provided with a pull chain, for the working of it.
The underside of the valve, has pronged leads, which conduct the valve centrally
to the open mouth of the branch inlet.
Figure 1 of the accompanying drawings, represents in longitudinal vertical section,
a silent syphon flushing cistern, and a water waste preventer, constructed and
arranged according to my invention. The flushing is made silent, by the admission
of air to the stand pipe, at or near the determination of the flush; whilst the cistern
is made a perfect water waste preventer, by the starting valve acting independent of
the pull. The said view also represents the initial admission of water to the
down-pipe, by the opening of the starting valve entrance, and the raising of the
valve.
Figure 2 represents a like sectional view as figure 1, but with the float of the
silent valve, fallen to its lowest position, thereby removing the said silent valve, con-
sisting of a rubber sleeve, from over the holes, made at the junction of the inlet leg,
with the bend of the stand-pipe. It also shows the water waste prevention or starting
valve, down upon its seat.
Figure 3 represents partly in elevation and partly in section, the said cistern,
showing the starting valve of the water waste prevention means, upon its seat, and
the piston and counterpoise weight, held in a raised position, by constant pressure
applied to the pull. Thus, water waste is prevented, by making the starting valve,
independant of the movement of the pull, so that should the pull be held, or tied
down, the valve's function is unchanged, as the same falls, immediately after being
lifted.
Figure 4 represents a borizontal section of the said cistern, through the dotted
lines B, figure 1.
Figure 5 represents the starting valve piston and casing.
Figure 6 is an underside view of the said valve, showing the leads for directing
centrally, and preventing the displacement of, the said valve, within and from the
starting valve entrance.
Figure 7 represents a modification of my invention.
The silent valve in this form, is raised and lowered, or taken into and out of
position, by the angular movement made by the ball valve stem.
Figure 8 is a transverse section, on the dotted lines C D figure 6.
The same letters of reference indicate corresponding parts in the several figures.
a is the Bush box or cistern, the stand pipe, directed vertically from the bottom
and middle of the said cistern, b² is a depending branch or leg, connected to the stand
pipe upper end, by a bend 63, whilst the lower end of the said stand-pipe, terminates
in a down or flushing pipe c, leading to the closet pan.
At the junction of the down pipe with the stand pipe, or at the lower end of the
stand pipe, is an open ended angle arm or branch d, d², down or through which water
is admitted to the down pipe, for creating a partial vacuum within the stand pipe
immediately above it. The water thus admitted acts alike unto a plunger, which

page_text: displaces the air on its descent, and creates a partial vacuum within the space vacated
by it, and the space approximate to the space thus vacated; now by the unequal
inside and outside pressure, water from the flush box, is forced up the branch of the
stand pipe.
e is a chambered valve, or water-waste preventer, with a plain piston or disc f
and stem f, working within it, and through its crown.
The piston rod is counterpoised by a weight f³, whilst its upper end f*, is con-
nected by a link f³, to the short arm g², of the lever pull g, fulcrumed at g³, and with
the chain pull h, connected at its outer end.
The chambered valve, has it underside e, faced with rubber or other yielding
material e³, and with angular guides or leads e, directed downwardly, and taking
within the open mouth 2, of the angle branch d.
The lifting of the lever g, by the pull, momentarily raises together both valve and
ston, when the water above the piston changes its position, or flows outwardly,
the valve immediately falls, and covers up the open end of the branch as aforesaid.
The branch or leg 2, of the stand pipe b, is pierced with holes i, at its junction
with the bend 3, and over which said holes, is a yielding sleeve valve j, carried by a
sliding tube, terminated by a float k, working upon the said branch or leg, as a
guide.
When the flush box is full, the holes are closed, by the outward pressure of the
water, pressing the rubber of the yielding valve, close over them, so as to seal them.
The falling of the float, by the flushing, removes the said valve from over the holes,
which thus admit air to the interior of the cistern, and prevents noise or gurgling, at,
or near the, termination of the flush.
The flush box is provided with a ball valve 7, valve stem 12, valve ³, bib l^, and
service entrance 15.
In figure 7, the silent valve, /, is operated by the ball float stem 12, of the float 1,
and connection is made by trunnions, on the two opposite sides of the carrying tube
or sleeve, of the valve, taking into slots 1, of a bracket or carrying arm,
in order that the valve may be raised and lowered in a direct line, with the axis of the
branch, upon which it slides, consequent upon the angular movement made by the
ball valve stem.
The other parts of the cistern are marked with the same letters of reference, as
the preceding figures.
OPERATION.
Assuming that the flush box is full, and that the flushing and valve parts are in the
positions as represented in figure 3, the pulling of the chain pull h, turns the lever
upon its centre, and raises the chambered valve, counterpoise weight, and piston disc,
together, into the position as represented in figure 1, when water passes through the
open mouth, or open top d², of the angle branch d, and from thence into the down
pipe c, and thereby removes by its gravitating effect, the air within the down-pipe,
and rarifies the air within the stand pipe, and bend at its top, whereby the water in
the cistern, is by the predominating outside pressure, forced up the leg or branch b²,
over the bend 63, and down the stand-pipe, and from thence delivered at great
velocity, to the closet pan, through the down pipe c.
The float, has placed the silent valve, in a position that the holes i, are
hermetrically sealed, by the closing of it over them.
After the chambered valve has been lifted, the same remains only suspended, so
long as the liquid remains in the upper part of it, above the piston disc, so that this
said valve remains in an elevated position only for a moment, or only after sufficient
water has been allowed to pass to the down-pipe c, for creating the necessary partial
vacuum within the syphon system.
Thus, after the valve has been raised, through the intervention of the water con-
tained within the upper part of its interior, it again falls, and becomes free of the
piston disc and rod, after being momentarily lifted, by the displacement or flowing of
the liquid from the said interior.

page_text: The loosing of the pull chain, after the valve has fallen, allows the piston disc, to
fall to the bottom of the interior of the valve, as represented in figure 2.
From the above description, it will be understood, that as the valve is unconnected
to the disc, rod, and pull, or raising means, other than through the intervention
of the liquid within the valve, it is impossible for the said valve to be held by the
pull, or the raising means.
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:- A flushing cistern syphon arrangement, consisting of a fixed stand-pipe,
and depending leg and bend, and with the former, provided with an open topped
angle arm or branch, wherethrough water for starting the syphon system, first passes,
substantially as described and set forth.
Secondly-A syphon flushing cistern, as described and set forth in figures 1, 2, 3,
4 and 7.
Thirdly-Providing a branch or leg, or the syphon means of a flushing cistern,
with air holes or openings, and a valve or means for closing them, whereby noise or
gurgling at the flush, or the termination of a flush, is prevented or reduced, sub-
stantially as described and set forth.
Fourthly Controlling or operating the noiseless valve 1, 2, by a float, either
independent of the ball valve, as in figures 1, 2, and 4, or in connection with the
ball valve, or its steun, as in figure 7, substantially as described and set forth.
Fifthly Picking up the water waste prevention valve, by or through the inter-
vention of the liquid contained within it, or disposed on the upper side of a disc
piston, working within its interior, substantially as described and set forth in
figures 1, 2, 3, and 7.
Sixthly: The water waste prevention means, of which the parts are construced,
arranged, and operate, as set forth in figure 1, 2, 3 and 7.
