COMPLETE SPECIFICATION.
Improvements in Syphon Cisterns and Water Waste Preventers
for Flushing Water Closets, Urinals, and for other like
purposes.
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
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention relates to syphon flushing cisterns and water waste preventers for
use in w.c.'s, urinals, and for such like purposes where a given quantity of water is
required for flushing and cleansing the same, our object being to provide au
improved arrangement for obtaining an effective and rapid syphonic action, by
means of the first pull of the chain and lever (instead of the pull and let go action
required to effect syphonage in flushing cisterns hitherto in use) whereby the
whole contents of the cistern may be discharged at each flushing without waste of
water or noise.
We will proceed to fully describe our improved arrangements with the assistance
of the accompanying drawings in which we have illustrated two different methods
setting forth the principle of our invention and how the same may be carried
into effect.
Figure 1. represents in vertical section a syphon flushing cistern with the parts
in their normal position.

position when raised by the pull.

perforations or water ways.

bucket.

A is the tank or cistern of the ordinary kind which is supplied from the main
service in the usual manner by the inlet pipe B, regulated and governed by the
ball valve and float C and D, an outlet or overflow pipe E is provided at the
opposite end of the cistern, a sunken well or recess F is in the bottom of the cistern
nearer to its one end than the other, this well being of the required depth is
circular (preferably) though it may be made oval, square, or any other convenient
shape, the corresponding fittings being of a similar outline, or the well may be a
fixture rising within the cistern, or it may be loose standing upon the floor of the
same, the syphon is composed of two pipes G, G', having a bend at the top thereof,
the pipe G which is of a curved form is connected by the screw nut H to the usual
delivery or flush pipe I leading to the closet pan, the underside of the bend or top
of the syphon rises somewhat higher than the cistern walls, the straight pipe G¹,
terminates with a funnel shaped flanged mouth J which descends slightly below the
top of the well F. Situated within the well is a bucket K the sides of which rise
as shewn, this bucket is formed with an abutment or projecting ledge L round the
interior walls of same, and is perforated in its base, Figure 6, to provide water
[Price 8d.1

page_text: ways M, studs or snugs N are upon the exterior of the base to support the bucket
if it should be required, and to ensure water way underneath the bucket.
Rising from the base of the bucket is a stalk or column O which acts as a guide
for and retains a loose disc P having snugs thereon Q for the purpose of preserving
water way when the disc rises (by the action of the syphon) against the flange of
the syphon pipe, but the same object may be gained by casting distance pieces upon
the underside of the flange of the syphon and using a perfectly plain disc. The
bucket K is attached to the lever R by suitable links or connections S and works
within the sunken well F.
OPERATION.
The action of flushing is as follows:-
The various parts being in their normal position as seen in Figure 1, when the
cistern or tank A is charged, the water will also have risen within the straight
pipe G, of the syphon to a common level with that in the cistern. By now
drawing down the chain R', the lever R is depressed thus raising the bucket K to
the mouth of the funnel J, Figure 2, the abutment or projecting interior ledge L
of the bucket bears against the flange of the funnel J of the syphon, by this action
the water is forced out of the bucket K and up the straight pipe G₁ of the syphon
to a higher level than before it was disturbed, thereby creating a partial vacuum in
the bend of the syphon pipe by the displacement of the confined air whereby the
syphonic action is at once set up thus starting the initial flushing, the water being
discharged down the curved pipe G to the delivery pipe I, thence to the w.c. or
urinal basin.
The water having been thus forced in to the syphon in the above described
manner the disc P is brought into action, as it instantly rises from the perforated
base of the bucket, and by. reason of the snugs Q thereon, is kept at a sufficient
distance from the mouth of the funnel J, to allow of a water way, whilst the
syphonic action is going on through the perforations and around the base of
the bucket. By these means the syphonage continues until the cistern is completely
emptied, no matter whether the bucket is in a raised or lowered position as the
disc P becomes sucked up to the mouth of the straight syphon pipe by the syphonic
action and there remains until the cistern is emptied, when it falls down into its
place guided by the stalk or column O and thus seals the perforations or water
ways M of the bucket ready for reaction when the cistern is again charged.
Furthermore the syphonic action is rendered noiseless by reason of the fact that
when the bucket K is lowered after being raised by the lever the air is able to pass
between the funnel mouth J and the bucket, and so preventing the gurgling sound
that usually takes place at the finish of syphonic action; the column of water in
the well of the cistern, deadening the noise.
The object and advantage of having a bend or curve in the delivery pipe of the
syphon, is that it allows of a column of water being formed instantly which causes
the syphonic action to take place more readily and effectively, but a straight pipe
may be used.
We will now refer to Sheet 2 of the annexed drawings in which an alternative
method is shewn in the various figures.
Figure 11 is a vertical section representing a syphon flushing cistern with the
parts in their normal position when the cistern is charged.
Figure 12 is a vertical section with the parts in action.
Figure 12 shews top of stand pipe with bar across.
Figure 13 is a sectional elevation shewing the syphon pipe and bell or dome in
connection therewith.
Figure 14 is a transverse sectional elevation.
Figure 15 is a horizontal section of the bucket on line C, D.
Figure 16 is a plan, and Figures 17 and 18, are side and plan views of the disc.
In this case we construct the cistern or tank A with a recessed or sunken well B
in its centre, the stand pipe or syphon C passes through the well and is connected

and leaving sufficient space around same for water ways M, a loose disc N having
snugs thereon fits down into the base of the bucket, metal connections P attach
the bucket by its sides to the arms of the lever Q as shewn.
OPERATION.
The cistern being charged, Figure 11, the water rises up the interior of the bell
or dome F level with that in the cistern; by depressing the lever Q by means of
the chain R, the bucket K is raised to the mouth of the bell, Figure 12, the water
is thus forced out of the bucket up the interior of the fixed bell to a higher level
than before, and thus displacing the confined air in the crown of the bell, thereby
creating a partial vacuum within the interior of the bell and upper part of the
stand pipe and so starting the initial flushing whereby syphonic action is at once.
set up, the water continuing to flow over the top of and down the stand pipe or
syphon until the cistern is exhausted of its contents. The water having been so-
forced up the disc N will rise to the mouth of the bell by the suction of the
syphonage, the snugs upon the disc keeping it a sufficient distance from the flange
of the bell, or instead of snugs upon disc, distance pieces may be cast upon the
under side of the flange of the bell or dome and a plain disc used as in the first.
alternative method to provide water ways. When the syphonage has ceased the
disc descends the stand pipe (which acts as the guide) back into position in the
base of the bucket.
It will be seen that in the above described methods the action is very similar.
Any suitable shape or description of well may equally apply to this second
arrangement, the working parts constituting our improvements being made to
correspond. Some of the parts, for instance, the bucket, the disc, and the bell or
dome may be either of metal, earthenware, or, other suitable substance.
We do not confine ourselves to the more precise details of construction and
arrangement of parts as herein described as we may vary the same to suit.
