Improvements in Flushing Apparatus for Water Closets and other
Places.
We, JOSEPH BREEDEN AND COMPANY LIMITED, of New Mill Works,
Fazeley Street, Birmingham in the County of Warwick, Manufacturers, and
FRANCIS BREEDEN, Director of Joseph Breeden and Company Limited,
aforesaid, Manufacturer do hereby declare the nature of this invention to be as
follows:-
The said invention consists of the improvements hereinafter described in syphon
flushing apparatus for water closets and other places whereby the setting up of
the syphon action by the forcing of the water over the crown of the syphon is
effected in a simple manner and a large displacement or flush of water for setting
up the flushing action obtained, together with the complete emptying of the
flushing cistern.
The displacement or flush of water, by which the syphon action is set up, may
either be effected by the pulling down and releasing of the pull down chain, or by
the pulling down only of the said chain.
We will first describe the flushing apparatus as put into operation by the pulling
down and releasing of the pull down chain.
In constructing a flushing apparatus according to this invention we make
preferably by the casting process at the bottom, and below the level of the bottom
of the cistern a curved well hereinafter called the water displacement chamber.
One end of the said chamber opens into the cistern and to the other end of the
said chamber we connect the short leg of the syphon, the long leg of the syphon
being secured to the bottom of the cistern in the ordinary way. The curved
displacement chamber, below the level of the bottom of the cistern, is of con-
siderably larger diameter than the syphon and the end of the short leg of the
syphon is connected to the curved displacement chamber by a bulbous shaped
hollow cap of larger diameter than the said displacement chamber for the purpose
hereinafter described.
In the said curved displacement chamber a piston or disc works freely, the said
piston being carried on the lower end of a weighted curved or quadrant shaped
arm or lever turning in a vertical plane on a joint carried by the long leg of the
syphon. The curve of the displacement chamber and that of the quadrant arm or
lever working in it are struck from the centre on which the said quadrant arm or
lever turns.
The jointed upper end of the curved or quadrant arm or lever
carrying the piston or disc is bent back or nearly at right angles to the other part
of the said arm. By means of a heel or stop on the said arm its descent is limited.
The short arm of the pull down lever is connected to the curved or quadrant
shaped arm by a link.
When the parts of the flushing apparatus are in their normal position the piston
or disc on the end of the curved or quadrant arm or lever is situated in the
bulbous shaped cap at the nearly closed end of the displacement chamber and in
this position of the piston or disc there is a free passage for the flushing water
between its edge and the bulbous cap to the short leg of the syphon.
On pulling down the chain of the pull down lever its short arm is raised and the
curved or quadrant lever turned on its centre and its piston or disc moved from the

page_text: On
cap end of the displacement chamber to the mouth or open end thereof.
loosing the pull down chain the weighted curved or quadrant lever descends and
its piston or disc makes a rapid return or back motion in the curved displacement
chamber and pushes before it or displaces the water in the said chamber. The
displaced water is forced up the short leg of the syphon and over the crown of the
syphon and the flushing action set up and the cistern thereby completely emptied
of its contents with the exception of the well or displacement chamber which is
left filled for the next flushing operation. As the piston at the end of its back or
displacing position is situated in the bulbous cap there is no obstacle to the free
passage of the flushing water from the cistern to the short leg of the syphon.
When the flushing action is set up by the pulling down only of the pull down
chain, the curved or quadrant lever is so weighted that its disc or piston is situated
in the normal position of the parts at the mouth or open end of the displacement
chamber. On depressing the pull down chain the short arm of the pull down lever
is raised and the curved or quadrant arm or lever so turned on its centre as to
force its piston or disc into the displacement chamber and effect the setting up of
the syphon action.

Improvements in Flushing Apparatus for Water Closets and other
Places.
We, JOSEPH BREEDEN AND COMPANY LIMITED, of New Mill Works,
Fazeley Street, Birmingham, in the County of Warwick, Manufacturers, and
FRANCIS BREEDEN, Director of Joseph Breeden and Company Limited,
aforesaid, do hereby declare the nature of the said invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
The said invention consists of the improvements hereinafter described in syphon
flushing apparatus for water closets and other places, whereby the setting up of
the syphon action by the forcing of the water over the crown of the syphon is
effected in a simple manner and a large displacement or flush of water for setting
up the flushing action obtained, together with the complete emptying of the
flushing cistern.
The displacement or flush of water, by which the syphon action is set up, is
effected by the pulling down and releasing of the pull down chain.
In constructing a flushing apparatus according to this invention we make
preferably by the casting process at the bottom, and below the level of the bottom
of the cistern, a curved well hereinafter called the water displacement chamber.
One end of the said chamber opens into the cistern and to the other end of the
said chamber we connect the short leg of the syphon, the long leg of the syphon
being secured to the bottom of the cistern in the ordinary way. The curved
displacement chamber, below the level of the bottom of the cistern, is of con-
siderably larger diameter than the syphon and the end of the short leg of the
syphon is connected to the curved displacement chamber by a bulbous shaped
hollow cap of larger diameter than the said displacement chamber for the purpose
hereinafter described.
•
In the said curved displacement chamber, a piston or disc works freely, the said
piston being carried on the lower end of a weighted curved or quadrant-shaped
arm or lever turning in a vertical plane on a joint carried by the hollow cap of the
syphon. The curve of the displacement chamber and that of the quadrant arm or

page_text: lever working in it are struck from the centre on which the said quadrant arm or
lever turns. The jointed upper end of the curved or quadrant arm or lever
carrying the piston or disc is bent back or nearly at right angles to the other part
of the said arm. By means of a heel or stop on the said arm its descent is limited.
The short arm of the pull down lever is connected to the curved or quadrant
shaped arm by a link.
When the parts of the flushing apparatus are in their normal positions the piston
or disc on the end of the curved or quadrant arm or lever is situated in the bulbous
shaped cap at the nearly closed end of the displacement chamber and in this
position of the piston or disc there is a free passage for the flushing water between
its edge and the bulbous cap to the short leg of the syphon.
On pulling down the chain of the pull down lever its short arm is raised and the
curved or quadrant lever turned on its centre and its piston or disc moved from the
cap end of the displacement chamber to the mouth or open end thereof. On loosing
the pull down chain the weighted curved or quadrant lever descends and its piston
or disc makes a rapid return or back motion in the curved displacement chamber
and pushes before it or displaces the water in the said chamber. The displaced
water is forced up the short leg of the syphon and over the crown of the syphon
and the flushing action set up and the cistern thereby completely emptied of its
contents with the exception of the well or displacement chamber which is left filled
for the next flushing operation. As the piston at the end of its back or displacing
position is situated in the bulbous cap there is no obstacle to the free passage of the
flushing water from the cistern to the short leg of the syphon.
We will now proceed to describe with reference to the accompanying drawings
the manner in which the said invention is to be performed.
Figure 1 represents in vertical longitudinal section, flushing apparatus constructed
according to the said invention; Figure 2 is a cross section of the same taken on
the dotted line x, x Figure 1 and Figure 3 is a plan of the same. In the said
Figures 1, 2 and 3, the moving parts are represented in the positions which they
respectively occupy after the pulling down of the pull down chain, but before the
release of the said chain: Figure 4 represents the same view as Figure 1 after the
pull down chain has been released and the flushing action set up in the cistern,.
the said cistern being represented partly emptied.
The same letters of reference indicate the same parts in the several figures of the
drawings.
a is the cistern and b the curved well or water displacement chamber at the
bottom and below the level of the bottom of the said cistern; c is the short leg of
the syphon and 2 the long leg of the same in connection with the down pipe c³ as
usual. It will be seen by reference to the drawings that the curved displacement
chamber b is of considerably larger diameter than the syphon and one end of the
said chamber opens into the cistern a, the other end of the said chamber being.
connected to the short leg c of the syphon by the bulbous shaped hollow cap d, the
part 2 of the water displacement chamber near its junction with the said cap
being enlarged for the purpose hereinafter described; e is a piston or disc working
freely in the curved water displacement chamber b. The said piston or disc e is
cast in one piece with the weighted curved or quadrant shaped arm or lever f
turning in a vertical plane on the joint or cross pin or pivot g working in the slotted
or forked upright or bearing carried by the cap d of the syphon. A slotted capi
retains the joint pin or pivot g of the quadrant arm or lever fin its slotted seat. It
will be seen that the upper end of the curved or quadrant arm or lever f, carrying
the piston or disc e, is bent back nearly at right angles to the other part, and the
said bent back portion is provided with the joint pin or pivot 9 on which the arm
or lever turns. The curve of the water displacement chamber 6 and that of the
quadrant arm or lever working in it, are struck from the centre or joint y on
which the said arm or lever turns. The quadrant arm or lever f is operate:l,
through the link m jointed to it at m², by the pull down lever n, the inner arm of
which is hooked to the link m and the outer arm carries the pull down chain p..

page_text: A heel on the turned back portion of the quadrant arm or lever f bearing against
the fixed buffer stop k limits the descent of the said arm or lever fand the advance
of the piston or disc e in the curved chamber b (see Figure 4); and the lifting of
the said arm or lever is limited by the stop on it coming against the link m.
When the parts of the Alushing apparatus are in their normal positions, represented
in Figure 4, the piston or disc e of the curved or quadrant arm f is situated in the
enlarged part at the junction of the cap d with the curved well or chamber >>
and in this position of the piston or disc, there is a free passage for the
flushing water between the edge of the said disc or piston and cap to the short leg c
of the syphon.
The action of the parts of the flushing apparatus is as follows:-On pulling
down the chain p of the pull down lever n, the short arm of the said lever is raised
and the curved or quadrant arm or lever turned on its centre 9 and the piston or
disc e is moved from the cap end of the displacement chamber b to the mouth or
open end thereof, the several parts now occupying the positions represented in
Figure 1. On loosing the pull down chain p the weighted curved quadrant lever f
descends and its piston or disc e makes a rapid return or back stroke in the curved
displacement chamber 6 and pushes before it or displaces the water in the said
chamber, the parts now occupying the respective positions represented in Figure 4.
In the said Figure 4, the cistern a is shown partly emptied by the flushing operation.
The water displaced from the chamber b is forced up the short leg c of the syphon
and over the crown of the syphon into the long leg and the syphon action
thereby set up, the flushing water descending the down pipe c to the place to be
flushed. It will be seen that when the piston e is at the end of its back stroke or
displacing position, it is situated in the wide part 2 near the cap d and hence there
is no obstacle to the free passage of the flushing water from the cistern to the short
leg of the syphon.
By the use of the apparatus described the cistern proper is completely emptied of
its contents, but the well or water displacement chamber b is left filled with water
after each flushing operation.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that we claim
as the said invention :-
The improvements in syphon flushing apparatus for water closets and other
places hereinbefore described and illustrated in the accompanying drawings, the
said improvements consisting essentially in the use of a curved well or water
displacement chamber at the bottom of the cistern, one end of the said well or
chamber opening into the cistern and the other end being connected by a hollow
cap to the short leg of the syphon; and the combination with the said curved
well or water displacement chamber of a piston or disc working therein and
carried by a weighted quadrant shaped arm or lever connected by a link with the
pull down lever of the apparatus, the pulling down of the pull down chain causing
the retirement of the piston or disc to the mouth or open end of the well or
displacement chamber and the releasing of the said chain causing the piston or
disc to make a rapid return or back stroke in the said well or displacement chamber
and push back or displace the water in the said chamber for setting up the syphon
action substantially as described and illustrated.
