Improvements in and relating to Syphon Cisterns and Water Waste
Preventers.
We GEORGE BRINDLEY of 50 Alma Street Aston near Birmingham in the
County of Warwick Plumber, JAMES MCEWEN and SAMUEL THOMPSON (trading
as Samuel Thompson & Co.) of Millfields Works near Wolverhampton in the
County of Stafford Ironfounders do hereby declare the nature of this invention
to be as follows:
Our invention relates to certain methods for syphon flushing cisterns and water
waste preventers for water-closets and urinals, by which we provide simple and
effective arrangements whereby waste of water is prevented and a rapid syphonic
action obtained.
We will describe our invention firstly as relating to one form by which our
improvements are effected.
The usual tank or cistern is employed having a well therein of any suitable kind
either loose or a fixture but by preference recessed from the base of the cistern
and cast in one therewith.
The stand pipe rises through the well to a given height in the cistern a
cylindrical or other shaped weighted bell or dome having a projecting flange or
footing at its base encases and works over the stand pipe by means of the usual
lever and chain or other connection.
In the sides of the bell or dome just above the flanged base are two or more
waterways; the flanged base is obviously of a corresponding form to the well.
The cistern is supplied in the usual manner and when charged the water will
also have risen up the interior of the bell by means of the water ways in the same.
By actuating the lever the bell is raised to a certain height its weight in
descending into the well acts upon the water therein thus forcing it up the interior
of the bell to its crown and over the top of and down the stand pipe displacing in
its passage the confined air in the bell and creating a vacuum thus setting up the
syphonic action and starting the initial flushing which continues to act until the
cistern is emptied.
Another method of our invention relates to an arrangement of bell or dome
having a flanged base as before and two independent semi-cylindrical vertical
chambers formed on each side of the centre chamber, water ways are provided at
the upper part of the inner walls of the bell and also at the base of each side
chamber.
The fittings of the cistern are of the ordinary description.
When the cistern is charged the water will have risen to a common level in the
bell and its side chambers.
The action of raising and lowering the weighted bell or dome causes the water
to be forced up the interior of the centre chamber in the first instance and over the
top of, and into the stand pipe, displacing the confined air whereby the syphonage
is started, the water flowing through the water ways at the base of the bell and
being sucked up the side chambers, and thence through the water ways at the top
to the stand pipe.
"By either of the above described methods effectual provision is made whereby
the whole contents of the cistern will be exhausted at each flushing and waste

page_text: prevented, furthermore the power of the syphonic action is greatly facilitated and
takes place immediately whereby the syphon being once charged there is no chance
of failure in its action.

Improvements in and relating to Syphon Cisterns and Water Waste
Preventers.
We GEORGE BRINDLEY of 50, Alma Street Aston near Birmingham in the
County of Warwick Plumber and JAMES MCEWEN and SAMUEL THOMPSON,
trading as Samuel Thompson & Co. of Millfields Works near Wolverhampton in
the County of Stafford Ironfounders, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had to the
accompanying drawings and to the figures and letters shewn thereon :-
Our invention relates to a certain method (or methods) for syphon flushing
cisterns and water waste preventers for water closets, urinals and the like
situations where a flush of water in a given quantity is required for cleansing
purposes by which we provide a simple and effective arrangement or arrangements
whereby waste of water is prevented and a rapid syphonic action obtained.
In the annexed drawings in which similar letters of reference indicate similar
parts,
Figure 1. illustrates in vertical section a bell syphon flushing cistern constructed
according to one form of our invention.
Figure 2. represents a part sectional elevation of same.
Figure 3 represents in vertical section a bell constructed according to the
second method of our invention.
Figure 4 represents the bell in side elevation.
Figure 5 a perspective view of same.
We will describe firstly our invention in relation to one arrangement we adopt,
by which our improvements are effected.
The usual tank or cistern A is employed having a well therein of any suitable
kind or shape, either loose or a fixture, but by preference recessed from the base of
the cistern B. and cast in one therewith, the stand-pipe C. rises through the well to
a given height in the cistern, a cylindrical or other shaped weighted bell or dome D.
having a projecting flange or footing E. (of a shape suited to the shape of the well)
at its base encases and works over the stand pipe by means of the usual arrangement
of lever and chain or other connection.
In opposite sides of the bell or dome and situated just above the flanged base,
are two or more water ways F.
The bell or dome D. with its water ways above the flange may be made in one
piece or in two or more pieces in such a manner as to give sufficient water way
above the flange or bell mouth.
The cistern is fitted and supplied in the usual manner by means of ball valve
and float and other accessory parts common in this class of cisterns and when
charged the water will also have risen up the interior of the Lell by means of the
said water ways.
The bell being in its normal position as in Figure 2, by actuating and depressing
the lever, the bell D is raised in the well B. as shewn in Figure 1 its weight in
descending by its gravitating effect exerts its pressure upon the water within the

page_text: well which becomes displaced and thus forced up the interior of the bell to its
crown and over the top of and down the standpipe C. to the supply pipe, displacing
in its passage the confined air in the bell and creating a vacuum thus setting up
the syphonic action and starting the initial flushing which continues to draw until
the cistern has been exhausted of its contents, when it will immediately refill ready
for the next discharge.
Referring to our second arrangement as shewn in Figures 3. 4. and 5. the
bell or dome has a flanged base similar to the last described, but in this case two
independent semi-cylindrical vertical chambers G. are formed on each side of and
cast in one with the centre cylinder or chamber H. thus forming a triplex bell,
water ways
I are provided at or near the upper part and in the inner walls of the
bell and also at the base J. of each side chamber by reason of the same being left
open and not reaching to the flange of the bell as shewn.
The accessory fittings of the cistern in this case also are of the ordinary
description and the well constructed in similar manner to that already described.
When the cistern is charged the water will have risen to a common level in the
bell and its side chambers.
The action of raising and lowering the weighted bell or dome causes the water
to be displaced and forced up the interior of the centre chamber H. in the first
instance and over the top of and into the staud pipe displacing the confined air
and starting the syphonage, the water flowing through the water ways I. and being
sucked up the ride chambers, and thence through the water ways J. to the
standpipe.
By either of the above described methods effectual provision is made whereby
the whole contents of the cistern will be exhausted at each flushing and waste of
water prevented, furthermore the power of the syphonic action is greatly facilitated
and takes place immediately it is set up, whereby the syphon being once charged
there is no chance of failure in its action.
We may modify the above described arrangements if requisite therefore we do
not confine ourselves to the precise details of construction set forth.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is,
Firstly. In a syphon flushing cistern and water waste preventer the arrangement
and special formation of the weighted bell or dome as described and shewn in
Figures 1 and 2 having apertures or water ways therein which bell or dome works
preferably within a recessed well or sunken part of the cistern and which by its
gravitating weight forces the confined water within the well up the inside of the
bell and over the top of and down the standpipe whereby syphonic action is set up
substantially as herein more fully set forth and described.
Secondly. In a syphon flushing cistern or water waste preventer the arrangement
and special formation of a triplex bell or dome shewn in Figures 3. 4 and 5,
consisting of independent cylindrical chambers in combination with one another
and situated side by side with the water ways therein, and operating in the manner
and for the purpose of producing syphonic action by the raising and lowering of
the said triplex bell within a sunken or other well of a syphon flushing cistern as
set forth and described.
Thirdly. The raising of water to a higher level or above the top of the stand-
pipe by either of the methods above described and set forth.
