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 has reference to syphon flushing apparatus for water closets
and other places in which the syphon action is set up by the forcing of the water
in the cistern over the crown of the syphon by the operation of a pivoted flap con-
nected to the pull down chain; and the said invention consists of the construction
and arrangements hereinafter described of the said pivoted flaps and parts connected
with them.
By constructing and arranging the parts according to this invention, a flap of
large area can be used and hence a large displacement or flush of water obtained
for setting up the syphon action, the displacement or flush of water being offected
by the back or return motion of the flap in the cistern on the loosing of the pull.
down chain. According to one of the arrangements of this invention, we joint to
the bottom of the cistern a flat flap weighted at its front or unjointed end, the said
flap extending over about two thirds of the bottom of the cistern and working
closely in the cistern. The jointing of the weighted flap may be conveniently
effected by making a middle knuckle on the leg of the syphon and jointing the
side knuckles on the flap to the said knuckle on the leg. The short leg of the
syphon is curved and bent towards the front or weighted end of the flap and opens a
short distance from the bottom of the cistern, a hole at about the middle of the flap
permitting of the flap making its rising and falling motion upon the said short leg
of the syphon. The weighted end of the flap works loosely against a curved plate
at one end of the cistern. The weighted flap is connected to a pull down lever the
axis of which crosses, and its ends work in, the sides of the cistern and the pull
down lever is operated by a pull down chain in the ordinary way.
When the parts of the flushing apparatus are in their normal positions, the flap
rests on the bottom of the cistern. On the pulling down of the chain, the short
arm of the pull down lever is raised and with it the hinged weighted flap. On
loosing the pull down chain the flap descends or makes its back or return motion
in the cistern by the weight at its front or unjointed end. By the descending or
back motion of the flap the water is displaced between it and the bottom of the
cistern and the displaced water forced up the short leg of the syphon and over the
crown of the syphon and the flushing action thereby set up.
The hinged flap may be jointed to one end of the cistern and extend to
the opposite end of the cistern, the said flap covering nearly the whole of the
bottom of the cistern instead of about two thirds as before described. In this
rrangement the flap has near its weighted end and on its upper side, a curved
tube closed at top, which on the motion of the flap works over the curved leg of
the syphon fixed in the cistern, the top of the said leg being open. The diameter
of the closed tube on the flap is considerably greater than that of the syphon leg
over which it works. On the back or descending motion of the weighted flap, a

page_text: portion of the water in the cistern is displaced by it and forced between the tube:
on the flap and the syphon leg into the open top of the said syphon leg and the
syphon action thereby set up.
Instead of arranging the syphon at or near the middle of the cistern as in the
arrangements already described the syphon may be situated at one end of the
cistern. In this case, the syphon is carried by a base plate which permits of
the ready application of the said syphon to the cistern. The base plate occupies
about one third of the bottom of the cistern, the weighted flap jointed to the
opposite end of the cistern, occupying the other two thirds of the bottom of
the cistern. The base plate of the syphon is supported a short distance from
the bottom of the cistern and the bottom of the short leg of the syphon
opens into the space between the said base plate and the bottom of the
cistern. The said base plate carries a curved diaphragm or division against which.
the weighted end of the flap works loosely. The descent of the flap causes a
portion of the water in the cistern to be forced between the cistern and the base
plate of the syphon, up the short leg of the syphon and over the crown of the
syphon to set up the syphon action. This arrangement permits of the pull down
lever being jointed near one end of the cistern and also permits of the pull down
lever being worked from either end of the cistern.
Although we have described the syphon action set up by the releasing and
descent of the pull down lever yet by slight modification of the parts the syphon
action may be set up by the raising of the pull down lever.

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 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 has reference to syphon flushing apparatus for water closets
and other places in which the syphon action is set up by the forcing of the water
in the cistern over the crown of the syphon by the operation of a pivoted flap con-
nected to the pull down chain; and the said invention consists of the construction
and arrangements hereinafter described of the said pivoted Haps and parts connected
with them.
By constructing and arranging the parts according to this invention, a flap of
large area can be used and hence a large displacement or flush of water obtained
for setting up the syphon action, the displacement or flush of water being effected
by the back or return motion of the flap in the cistern on the loosing of the pull
down chain.
According to one of the arrangements of this invention, we joint to the bottom
of the cistern, a flat flap weighted at its front or unjointed end, the said flap
extending over about two thirds of the bottom of the cistern and working closely
in the cistern. The short leg of the syphon is curved and bent towards the front
or weighted end of the flap and opens a short distance from the bottom of the
cistern, a hole at about the middle of the flap permitting of the flap making its
rising and falling motion upon the short leg of the syphon. The weighted end of

page_text: the flap works loosely against a curved plate at one end of the cistern. The
weighted flap is connected to a pull down lever the axis of which crosses and its
ends work in the sides of the cistern and the pull down lever is operated by a pull
down chain in the ordinary way.
When the parts of the flushing apparatus are in their normal positions the flap
rests on the bottom of the cistern. On the pulling down of the chain, the short
arm of the pull down lever is raised and with it the hinged weighted flap. On
Joosing the pull down chain, the flap descends or makes its back or return motion
in the cistern by the weight at its front or unjointed end. By the descending or
back motion of the flap, the water is displaced between it and the bottom of the
cistern and the displaced water forced up the short leg of the syphon and over the
crown of the syphon and the flushing action thereby set up.
The hinged flap may
be jointed to one end of the cistern and extend to the opposite end of the cistern,
the said flap covering nearly the whole of the bottom of the cistern instead of
about two thirds as before described. In this arrangement the flap has near its
weighted end and on its upper side, a curved tube closed at top, which on the
motion of the flap works over the curved leg of the syphon fixed in the cistern, the
top of the said leg being open. The diameter of the closed tube on the flap is
considerably greater than that of the syphon leg over which it works. On the
back or descending motion of the weighted flap, a portion of the water in the
cistern is displaced by it and forced between the tube on the flap and the syphon
leg into the open top of the said syphon leg and the syphon action thereby set up.
Instead of arranging the syphon at or near the middle of the cistern as in the
arrangements already described, the syphon may be situated at one end of the
cistern. In this case the syphon is carried by a base plate which permits of
the ready application of the said syphon to the cistern. The base plate. occupies
about one third of the cistern, the weighted flap jointed to the opposite end of the
cistern, occupying the other two thirds of the bottom of the cistern. The base
plate of the syphon is supported a short distance from the bottom of the cistern
and the bottom of the short leg of the syphon opens into the space between the
said base plate and the bottom of the cistern. The said base plate carries a curved
diaphragm or division against which the weighted end of the flap works loosely. The
descent of the flap causes a portion of the water in the cistern to be forced
between the cistern and the base plate of the syphon, up the short leg of the
syphon and over the crown of the syphon to set up the syphon action.
This arrangement permits of the pull down lever being jointed near one end of
the cistern and also permits of the pull down lever being worked from either end
of the cistern.
Although we have described the syphon action set up by the releasing and
descent of the pull down lever, yet by slight modification of the parts the syphon
action may be set up by the raising of the pull down lever.
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 longitudinal section and Figure 2 in plan, flushing
apparatus constructed according to the first described arrangement of this
invention, the weighted flap being represented in its lowered or normal position;
Figure 3 represents the same view as Figure 1 after the weighted flap has been
raised by the raising of the pull down lever ready on the loosing of the pull down
chain to set up the syphon or flushing action.
The same letters of reference indicate the same parts in the several figures of
the drawings.
a is the cistern carrying the usual ball cock b ; c, d is the syphon, c being
the short leg and d the long or descending leg; e is the flap jointed at e to the
bottom of the cistern a, the said flap extending over about two thirds of the bottom
of the cistern and working closely in the cistern. The said jointed flap e is
weighted at its front end e so that when at liberty to fall it takes the lowered
position represented in Figures 1 and 2. The said flap is jointed to the cisteru by

page_text: its joint pine working between the half knuckle on the bottom of the cistern
and the half knuckle 9 made in one piece with the descending leg d of the syphon
(see Figures 1 and 3). By screwing the syphon in its place the jointed flap e is at
the same time jointed to the cistern. The short leg c of the syphon has the figure
represented that is, it is bent towards the weighted end of the flap and opens a
short distance above the bottom of the cistern. In the said flap is a hole h which
permits the said flap to rise and fall upon the short leg c of the syphon and the
weighted end of the flap works loosely against the curved end plate i; k is the pull
down lever, the inner arm of which is connected by the link to the flap e near its
joint.
On
The parts of the flushing apparatus being in their normal positions, the jointed
flap e rests on the bottom of the cistern as represented in Figures 1 and 2.
pulling down the chain of the pull down lever k, the inner short arm of the said
lever is raised and with it the link and hinged weighted flap e the said parts
taking the positions represented in Figure 3. On loosing the pull down chain, the
weighted flap e descends or makes its back or return motion in the cistern. By
the descending or back motion of the flap e water is displaced between it and the
bottom of the cistern and the displaced water forced up the short leg of the syphon
and over the crown of the syphon into the descending leg and the syphon action
thereby set up and the flushing of the closet or place effected.
Figures 4, 5 and 6 represent in section and plan respectively a flushing apparatus
constructed according to the second described arrangement of this invention,
Figures 4 and 6 representing the jointed flap in its lowered or normal position and
Figure 5 the flap raised for effecting the flushing operation.
In this arrangement the hinged weighted flape is jointed at e² to one end of the
cistern and extends to the opposite end of the cistern, the flap covering near the
whole of the bottom of the cistern. The said flap is connected near its joint end
to the pull down lever by the link l. In this arrangement the flap is jointed to
the cistern by the pivot ends of its joint pin taking into the end seats or
knuckles m at the sides of the cistern. These seats are open at one side and the
pivot ends of the joint pin are introduced into the open sides of the said seats
when the flap is in a nearly vertical position. By then lowering the flap the pivots
engage with the seats and are retained in the said seats by the plate i near which
the weighted end of the flap works. The said flap e has on its upper side and near
its weighted end, the curved tube e closed at top. The said closed tube e works
over the curved down leg d of the syphon, the top of the said leg being open as
represented. It will be seen that the diameter of the closed tube et on the flup e is
considerably greater than that of the syphon leg d thereby leaving an annular
space or passage between the two parts as represented.
When the flap e has been raised by the pull down lever k and link the parts
оссиру the respective positions represented in Figure 5 and on loosing the pull
down chain, the back or descending motion of the weighted flap causes the water
below the flap to be displaced and forced between the tube e and the syphon leg d
and over the open top of the said leg down which it descends and sets up the syphon
action as will be understood by an examination of Figure 5.
Figure 7 represents in longitudinal section with the flap in its lowered position,
the arrangement of this invention in which the syphon is situated at one end of
the cistern, the flap being jointed to the opposite end of the cistern; Figure 8
represents a plan of the same; Figure 9 a longitudinal section with the flap in its
raised position and Figure 10 a cross section through the syphon.
In this arrangement the syphon c, d is carried by the base plate p which
permits of the ready application of the syphon to the cistern. The greater part
of the base plate p is supported a short distance from the bottom of the cistern a
so that the water in the cistern has access under the said seat to the short
leg c of the syphon. The said seat p is provided with sockets into which the
short and descending legs of the syphon c, d are fitted and the socket part of the
short syphon leg is extended upwards and constitutes the curved plate i against

page_text: which the weighted end of the flap works. The flap e is jointed by its pinto.
the middle of the bottom of the cistern in the manner last described and the said
flap is raised by the pull down lever and link 1. The action of this arrangement.
of the invention is the same as that of the arrangement represented in Figures 1, 2
and 3, excepting that the flushing water enters the syphon leg by the passage.
under the base plate instead of directly into the syphon leg.
Figures 11, 12, 13 and 14 represent the arrangement last described modified in
order that the syphon action may be set up by the raising of the pull down lever-
instead of by the releasing and descent of the pull down lever: Figures 11 and 13.
represent longitudinal sections of the flushing apparatus, Figure 11 being taken
through the middle of the cistern and Figure 13 being taken through the cistern
at one side; Figure 12 represents a plan and Figure 14 a cross section of the same..
In Figure 11 the jointed flap is represented in its raised or normal position and
in Figure 13 in its lowered position after the syphon action has been set up by
its descent.
In this arrangement the inner arm of the pull down lever k is weighted and is
connected through the link to the extension e of the jointed flap e su as to joint
the link beyond the pin or centre e on which the flap turns. The joint pin e*.
works in the separate knuckle 9 pinned to the middle of the cistern. By thus.
jointing the flap e, it takes when the pull down chain is released, the raised position
represented in Figure 11 ready to effect the flushing operation when the pull
down chain is depressed, that is, on pulling down the outer arm of the pull down,
lever its inner weighted arm is raised and with it the link l. The jointed flap is
thereby turned down on its joint and made to take the lowered position represented
in Figure 13. As the flap e descends it forces before it a portion of the water in
the cistern into the short leg of the syphon and over the bend or crown of the
syphon into the descending leg and thereby sets up the syphon action as before
described. On loosing the pull down chain the inner weighted arm of the pult
down lever descends and lifts the flap into the position represented in Figure 11.
The method of jointing the flap last described combined with the weighted pull
down lever may be applied to the arrangements Figures 1, 2, 3, 4, 5 and 6, so.
that the syphon action inay be set up by the raising of the pull down lever instead
of by the releasing and descent of the pull down lever.
Having now particularly described and ascertained the nature of this inven--
tion and the manner of performing the same, we declare that we claim as the
said invention of "Improvements in flushing apparatus for water closets and other
places"-
