Improvements in Syphon Flushing Cisterns for Various Purposes.
I, ENOCH WASDELL of Shustoke in the County of Warwick, Foreman, do hereby
declare the nature of this invention to be as follows:-
This invention relates to that class of syphon flushing cisterns, in which a bell and
down pipe
arranged, and with a flanged mouth of the former working piston like
within a recess or sunken part, in the bottom of the cistern, at the junction of the
down pipe with the cistern."
When in use, the bell is counterpoised by a weight at the end of a lever, con-
nected to the top of the bell, so that on the said bell being pulled downwards by a
chain or the like, the flanged bottom practically enclosing the water beneath it in the
recess, causes the water to rise up the inside of the bell, and over the open top of
the down or stand pipe, whose bell mouth extends just above the level of the top of
the said cistern.
By my invention, the weight of the bell itself, displaces the water, on the chain
being loosed for flushing.
In carrying out my invention, I make the mouth of the bell in the form of an
extended solid flange, which works piston like within a well or sunken part in the
bottom of the cistern; at the foot or hilt of the down or stand pipe. Thus, the said
bell is sufficiently weighted or heavy that its gravitating effect will force the water
under its flange within the well, up its inside, to above the height of the mouth of
the downpipe, when the said water flows down the said downpipe, and creates a
vacuum within the inside crown of the bell, and so starts the flushing.
The lever for picking up the bell, is of the first order, that is, it is jointed between
its connection with the bell and the chain; so that by pulling the chain, the bell is
picked up, and when released, its weight as aforesaid, causes water to rise within its
interior.
As an alternative method, the bell may be weighted, by counterpoising the bell
side of the lever. Or instead of the bell having a solid flange, it may have a turned
up flange, with a weight surrounding the body of the bell.
.
Instead of employing a weight as a means for pulling down the bell, on the chain
being released, a spring may be substituted therefor.

Improvements in Syphon Flushing Cisterns for Various Purposes..
1 ENOCH WASDELL of Shustoke in the County of Warwick, Foreman, 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 syphon flushing cisterns, consisting of a bell
and down pipe, and with the former, or the flanged mouth of the bell, working
piston like over the said down pipe, and within a recess, or sunken part, in the
bottom of the cistern.
In the principle form of my invention, the weight of the bell itself, displaces the
water, for the initial charging of the syphon or down pipe thereof.

page_text: In carrying out one form of my invention, I make the mouth of the bell in the
form of an extended solid flange, which works piston like within a well or sunken
part in the bottom of the cistern.
The said bell is sufficiently weighted or heavy, (that its gravitating effect) to force
the water under its flange, up the inside of the said bell, and over the mouth of the
downpipe, thereby creating by the displacement of the air, a partial vacuum within
the inside crown of the bell and upper part of down pipe, and so starting the flushing,
which is continued, until the cistern is complety emptied.
The lever for picking up the bell, is preferably of the first order, viz. :-it is
jointed between its connection with the bell and the chain; so the pulling of the
chain, picks up the bell, and the releasing of it, causes the said bell's weight to force
the water to the desired height.
As an alternative, the bell may be weighted, by counterpoising the bell side of the
lever. Or instead of the bell having a solid flange, it may have a turned up flange,
with a weight surrounding its body.
Instead of employing a weight as a means for pulling down the bell, on the chain
being released, a spring may be substituted therefor.
Another form of my invention, consists in disposing the flange, which is upon the
lip of the bell, to the shank of the down or stand pipe.
In carrying out this second part of my invention, I take an ordinary cistern, and
place within it, an erect down pipe, whose open end is a little higher than the top of
the cistern. The lower or root end of the said down pipe, I provide with an annular
piston like flange, which remains immovable with the down pipe, and over which, the
expanded lower end of the bell works, and when in its normal position, the lip of the
said expanded part comes nearly opposite the flange; so that when the bell is lowered,
the water within the bell above the piston flange, is raised to a higher level, by the
diminished internal. cubical capacity of the said bell. Thus, the bell is like that of a
hollow pillar, with a trumpet end, which works trunk like over a fixed piston, and by
such working, the water confined within the interior is compelled to rise, or be dis-
placed to a higher level, and then flow over the top of the down pipe, which thereby
creates a partial vacuum within the interior of the bell and down pipe, and so starts
the flushing.
The lever for picking up or operating the bell, may be of the first or second order.
If of the former, it is jointed between its connection with the bell and the pull chain ;
so that by the pulling of the said chain, the bell is picked up, and then released, when
its weight or gravitating effect causes the water to rise within the interior of the
bell, to a height above the mouth of the down pipe; so it will be thus seen that it is
the releasing of the pull, that the starting of the flushing is effected.
As an alternative method, the bell may be made to rise, by a counterpoise weight,
and the initial starting of the flushing performed by the pulling of it down by the
chain; so that in this modification, the pull forces the water to a higher level, through
the intervention of the mouth of the bell working over the fixed piston, or annular
flange, which is of about its inside diameter.
Figure 1 of the accompanying drawings represents in vertical section, a bell-
syphon flushing cistern, constructed according to one form of my invention. It will
be seen that the lip of the bell has a plunger like flange, which works loosely with a
like shaped well, sunken or made within, the bottom of the cistern, and that the said
bell is weighted, and when loosed after being pulled or raised, falls and exerts its
pressure upon the water beneath it, which becomes displaced and forced to a level,
and above the mouth of the down or stand pipe.
Figure 2 represents the said cistern, with the bell with flange at its mouth end
raised, or in the position which it assumes, just before the pull is released.
Figure 3 shows a transverse section of the well, in order to exhibit the rest lugs
of the bell, at the bottom thereof (the section is on the dotted lines A B figure 2).
Figure 4 represents a horizontal section of the bell on the dotted lines C, D,
figure 2, thus showing particularly the flange of it.

page_text: Depress the pulle, when the bell d is picked up, to about the height of the abut-
ment flange h, then release the chain, when the bell by its own weight falls, and
thereby forces the water confined in the expanded mouth of the bell above the
abutment flange, up the contracted part of the said bell, and over the top of the
stand pipe, thereby displacing the air within the inside crown of the hell, and upper
part of stand pipe, which starts the syphon-arrangement.
The weight of the bell is above the weight of the column of water to be raised
within it.
Figure 8 represents a modification of this last form of my invention; the bell is
depressed only, to pass the water contained within its lower part, to a level, that it
will flow over, and down the stand pipe, for the starting of the flushing.
a is the flush box, b the stand pipe, with abutment or plunger flange h, c the outlet
to the closet, d the bell, with expanded mouth end d, working over the abutment /,
f is a lever, with a counterpoise weight f³, sufficient to bring the bell back to its
normal position as shown. f is a bracket for supporting joint f of lever, and e
is the pull, whilst the bell is prevented from coming on bottom of flush box by
snugs a³.

page_text: OPERATION.
Pull the chain, when the bell will be forced down, and water above the abutment
raised to the open mouth, and down the stand pipe, when the starting of the flushing
is effected. On the release of the chain, the parts resume their normal position, as in
the said figure 8.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
First A syphon flushing cistern, consisting of weighted bell, with a flange at its
lower and mouth end, which works piston like within, a well or sunken part in the
bottom of the cistern or flush box bottom, whereby the loosing of the bell, after being
raised, forces by its gravitating weight, the confined water within the well, or sunken
part, up the inside of the bell, and over the top of the stand pipe, for the purpose
substantially as described and set forth in figures 1, 2, 3 and 4.
Secondly-Starting the flushing, of a syphon flushing cistern, by the gravitating
force exerted on the releasing of a weighted and flanged bell, substantially as described
and set forth.
Thirdly-A syphon-flushing cistern, displacing water for initial flushing, or raising
water to the open mouth of the stand pipe, by an abutment flange upon the said stand
pipe, over which, the bell or the expanded open bottom of the bell, works, substantially
as described and set forth in figures 5, 6, 7 and 8.
:
Fourthly Raising water to a higher level, or above the mouth of the down or
stand pipe, for the purpose as described and set forth, by a counterpoised or weighted
bell, working over an abutment or piston flange, substantially as described and
illustrated in figures 5, 6 and 7.
