Improvements in the Action of Syphon Cisterns and Water Waste
Preventers.
I GEORGE BRINDLEY of Alma Street Aston near Birmingham in the County
of Warwick Plumber, do hereby declare the nature of this invention to be as
follows:-
This invention refers to syphon flushing cisterns and water waste preventers for
w.c.'s urinals and such like and consists of the usual cistern or tank for containing
the supply of water.
Rising within the cistern is the stand pipe in immediate connection with the
supply pipe which is continued from the cistern to the w.c. basin, or urinal.
Situated at the base of the stand pipe within the cistern is a cylinder or
cylinders of a peculiar formation which I will call a duplex cylinder inasmuch as it
is divided into two compartments.
Between these two compartments and facing the narrow width or sides of the
cistern or tank a space or recessed portion is left on either side of the stand pipe
and open to same the return of the walls of the cylinders to the stand pipe not
quite touching the stand pipe so as to provide a water way or channel to allow of
the inflow of water to the duplex cylinder.
Working over the stand pipe is a weighted bell the footings or lower terminations
of which shall be of the same formation as the duplex cylinder into which the bell
descends.
Upon the lower edge of the weighted bell on either side thereof is a cut out slot
or opening for the access of water thereinto when the cistern is filling.
A lever of any suitable kind having a chain or other connection attached
thereto will be used for raising and lowering the weighted bell.
The requisite supply of water to the cistern will be regulated by means of a
ball valve and float the rise and fall of which determines the supply also the usual
overflow pipe will be provided.
The cistern being in its normal condition .. full the water in supplying the
cistern also.rises within the weighted bell through the slots at bottom of same.
By actuating the chain or other lever connection the bell is raised and depressed
its weight in descending causes the water within the duplex cylinder to be forced
up the interior of the bell over the top of and down the standpipe displacing in its
passage the confined air within the bell thereby creating a vacuum and starting
the syphonic action the water continuing to flow through the channels or water
ways on either side of the duplex cylinder and into the same until the cistern is
empty when the cistern immediately refills ready for the next discharge.
By this formation of bell and cylinder it will be found that the whole contents
of the duplex cylinder and cistern will be exhausted at each flushing before the
syphonic action ceases, the advantage of the duplex cylinder and the object for
which it is designed is that it will greatly facilitate the power of the syphon action
whereby the syphon being once charged there is no chance of its failure, true
syphonage being thus obtained and waste of water prevented.

Improvements in the Action of Syphon Cisterns and Water Waste
Preventers.
I GEORGE BRINDLEY of Alina Street Aston. near Birmingham in the County
of Warwick Plumber, 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 :-
My invention relates to a method of syphon flushing cisterns and water waste
preventers for water closets urinals and such like situations where a flush of
water of a given quantity may be required for cleansing the paus or basins of
same and my object is to provide a simple and effective arrangement for the
purpose named and one whoreby waste of water is reduced to a minimum.
Referring to the accompanying drawings
Figure 1. illustrates in sectional elevation one form by which I carry my
invention into effect,
Figure 2. is a plan of the same and
Figure 3. is an elevation of the bell or dome I prefer to use in this case.
Similar letters of reference relate to similar parts on the figures.
I will describe my invention firstly as referring to what I term a duplex arrange-
ment of well or cylinder with the other working parts in connection therewith.
I employ the usual tank or cistern A for containing the regulation supply of
water rising with the tauk or cistern is the stand pipe B in immediate connection
with the supply or discharge pipe C to the pan or basin. Situated at the base of
the stand pipe B within the cistern is a well cylinder or cylinders D of peculiar
formation which I call a duplex well or cylinder inasmuch as it is divided into two
compartments as shewn.
Between these two compartments and facing the narrow width or sides of the
cistern or tank, spaces or recessed portions E are left on either side of the stand
pipe B and open to same thic return of the walls D' of the cylinders or wells D to
the stand pipe not quite touching the stand pipe so as to provide a water-way or
channel D to allow of the inflow of water to the duplex cylinders or wells D.
Working over and encasing the stand pipe is a weighted bell or dome F the
footings or lower terminations F¹ of which shall be of the same outline or
formation as the cylinders or wells into which the bell has to descend the bell or
dome F, is cut out on its lower edge thereof Fu Figure 3 to form apertures on
either side to allow for access of water thereinto when the cistern is charging.
A lever G of any suitable kind for raising and lowering the bell or dome and
having a chain Gand handle (lever rod or other means) for manipulating the
same may be used.
The cistern or tank will be charged with the requisite supply of water by the
ordinary means and regulated by ball valve and float H, H the rise and fall of
which determines the supply. An overflow pipe I carries off any superfluous
water.
The cistern being in its normal condition i.e. full, the water in supplying the
cistern also rises within the bell or dome F the water obtaining ingress through
the waterways F", D".
OPERATION.
By actuating the chain or other lever connection G' the lever G is depressed
thus raising the bell or dome F, its weight in descending causes the water within
the double wells or duplex cylinders D to be forced up the interior of the bell or
dome and over the top of and down the stand pipe B displacing in its passage
the air confined within the crown of the bell thereby creating a vacuum and thus

page_text: setting up syphonic action and starting the initial flushing the water continuing to
flow through the channels or water-ways D" provided for the purpose on either
side of the duplex wells or cylinders D until the cistern or tank has been
exhausted of its contents when it will immediately refill ready for the next
discharge.
By this formation of the interior portions of the cistern or tank it will be found
that the whole contents of the cistern will be exhausted at each flushing before the
syphonic action will cease, the advantage of the duplex woll or cylinder aud the
main object for which it is designed is that it will greatly facilitate the power of
the syphon action whereby the syphon being once charged there is no chance of
its failure.
As an alternative I may if preferred dispense with the intermediate walls D¹ of
the wells or cylinders, in which case water-ways will be made on either side of the
well also at each end if necessary.
A further alternative method is shewn in sectional elevation Figure 4, Figure 5
being a plan of same and Figure 6 an elevation of the particular form of dome or
bell I use in connection with this modification of my invention.
It will be seen in plan Figure 5 that in this case I use a single well or cylinder J
of au oblong form by preference and at the base of which are openings K for
ingress of water to the well or cylinder this well surrounds the stand pipe L as in
the usual way."
The dome or bell M that I employ with this arrangement is of special
formation viz. it is curved or hollowed, back, and front on its flanged base, seo N
Figures 4 and 6 this allows a passage for water to enter and rise within the dome
or bell when the cistern is charging.
The auxiliary parts in the construction of this form of syphon cistern will be
similar to those already described in relation to my previous method.
The flushing operation will be effected by the raising and lowering of the dome
or bell as usual by the operation of the lever the syphonic action being set up by
the inrush of water through the water-ways K and N in the well and dome and
consequent displacement of air, the syphoning continuing until the cistern is
entirely empty.
Various modifications of my invention can be adopted without departing from
this my improved principle, therefore I do not confine myself to the exact details
herein set forth and described but by preference I construct the cistern and well or
cylinder also the specially shaped base of the dome or bell as shewn in
Figures 4, 5, and 6, as the friction of the parts is reduced to a minimum and great
simplicity of action obtained.
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
olaim is:-
Firstly. In a syphon flushing cistern the arrangement and special formation of
the double well or duplex cylinder the formation of the dome or bell working
within such double well or duplex cylinder for the purpose of forcing by its
gravitating weight (after being raised) the water within such double well up the
bell and over and down the stand pipe whereby syphonic action is started by
displacement of air substantially as herein more fully set forth and described in
Figures 1, 2, and 3.
Secondly. In a syphon flushing cistern the arrangement and formation of the
parts as illustrated in Figures 4, 5, and 6, and described in relation thereto con-
sisting of the well or cylinder as shewn, the specially shaped curved flanged dome
or bell, and the general parts in connection therewith substantially for the purpose
and working as herein more fully set forth and described.
Thirdly. In a syphon flushing cistern or water waste preventer the general,
arrangement and combination of the various portions forming my improvements
