Improvements in Syphon Flushing Cisterns.
We THOMAS SHUTT STOCK, WALTER STOCK, BERNARD STOCK, HENRY
WILLIAM TAYLOR and THOMAS LEA TAYLOR, trading as Stock, Sons, &
Taylors of Berkeley Street Brass Foundry Birmingham in the County of Warwick
Brass Founders, and THOMAS SINGLETON of 25, Arthur Street Small Heath
Birmingham aforesaid Fitter, do hereby declare the nature of this invention to be
as follows:-
:-
This invention relates to an improved construction and arrangement of syphon
cistern whereby effective means are provided for creating the flush of water by
syphonic action, and preventing any waste; and it consists in forming the syphon
by casting two pipes side by side and having a bend at top connecting them, the
one pipe is in connection with the supply to the pan or basin, the second pipe has
cast upon its one end at right angles thereto, a cylindrical chamber which may
be circular or other approved shape, and which is raised a certain height from the
cistern floor to allow of free water way.
די
Soldered or otherwise suitably attached within this chamber is a copper,
brass, or other metal cylinder, having a base plate thereon perforated with water
ways.
in constructing this part of our invention the cylinder is passed into position
in the aforesaid chamber from the under side thereof, the base plate fitting
up flush with same, and being attached thereto by bolts and nuts, or screws, passing
through flanges or ear pieces upon the base plate and upon the chamber.
Within the lower part of the copper or other metal cylinder and connected to
the centre of the perforated base plate a column or guide rises to a certain height,
round which is a loose metallic disc which rises and falls as hereinafter shewn.
Level with the top of this column is a rim or projecting metallic ledge around the
inside of the cylinder.
A plunger works piston like within the cylinder which plunger may consist
preferably of a metal disc and rod for connection to the lever, which latter takes
its bearing upon the sides of the cistern, farther from the pull down end than
ordinarily is the case so as to give the required leverage; the end of the lever is
provided with a weight to counterpoise the same when in action.
By depressing the lever, the plunger is forced down into the aforesaid cylinder
(as far as the metal rim or ledge) thus causing the water in the cylinder to rise
up and over the top of the syphon and as soon as it reaches the bend, displaces
the confined air, thus creating a vacuum within the syphon and starting the initial
flushing by setting up the syphonic action which continues to draw the water from
the cistern up through the lower compartment of the cylinder until it is entirely
emptied.
Immediately the syphonage commences the inrush of water to the syphon
causes.the aforesaid loose disc to rise up the column or guide to its top and to
the under side of the rim or ledge and so seals the water way between the
lower and upper part of the cylinder the plunger meanwhile rises to its normal
position the counterpoising weight upon the lever effecting this as it depresses the
end of same.
The water as it charges the cistern flows into the cylinder and the loose dise
descends to its original noint

page_text: By these means a rapid syphonic action is provided which when once set up enables
the cistern to be completely emptied of its contents, without liability of the syphonage
ceasing until this is effected.

We THOMAS SHUTT STOCK, WALTER STOCK, BERNARD STOCK, HENRY
WILLIAM TAYLOR and THOMAS LEA TAYLOR, trading as Stock Sons &
Taylors of Berkley Street Birmingham in the County of Warwick Brassfounders
and THOMAS SINGLETON of 25, Arthur Street Small Heath Birmingham aforesaid
Fitter, 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, reference being had to the drawings hereunto annexed and
'forming part of this Specification and .in which we have illustrated the method of
our invention.:-
Our invention relates to an improved construction and arrangement for syphon
'cisterns and water waste preventers for use in wic's urinals and for such like
purposes in which a fixed amount of water is allowed only at a given time to be
delivered from the cistern which contains same, to the pan of the w.c. urinal basin
"or other object requiring to be flushed for cleansing and purifying purposes, and
our object is to provide improved means for creating the flush of water by a rapid
"and silent syphonic action whereby the contents of the cistern may be entirely
discharged at ench flushing and thus producing a perfect water waste preventer.
We will now proceed to fully describe our improved arrangements with the
assistance of the drawings in which similar letters of reference indicate similar
parts on the figures.

J
A is the cistern of the ordinary or other suitable kind supplied from the main
service by the inlet B. regulated and governed by the ball valve and float C and D
and overflow E. Situated within the cistern are two vertical: pipes E. G. com-
posing the syphon, cast side by side, and having a bend or elbow H. at the top the
longer pipe F. is in immediate "connection with the supply or discharge pipe I.
leading to the pan or basin the shorter pipe :G.1terminates as shewn and has cast
upon its end at right angles thereto a cylindrical chamber J. which may be circular
or other approved and convenient shape, and which is raised a certain height from
the cistern floor to allow of free water way K beneath same, suitably attached

page_text: within this chamber J either by soldering riveting screwing or otherwise, is a copper
brass, or other metal cylinder. L. having its base plate .L' perforated to form water
ways.
!
In constructing this part of our invention the copper or other cylinder L is
passed into position in the aforesaid chamber J from the underside thereof the base
plate L' fitting up flush with same and being attached thereto by means of bolts
and nuts or screws M passing through flanges or ear pieces N. upon the base plate
and upon the chamber. Within the lower part of the copper or other metal
cylinder L and connected to the centre of the perforated 'base plate a vertical
column or guide O rises to a certain height round which is a loose metallic disco
which rises and falls by the action of flushing as hereinafter described.
'Level with the top of this coluinn which will be about one third (more or less).
of the total height of the copper cylinder L and in connection therewith is a
circular rim or projecting metallic ledge P. soldered upon the inside and integrál
with the cylinder.
It will be clearly seen that the cylinder L. with its chamber at base J. is provided.
with a water way leading immediately into the syphon.
A plunger Q works piston like within the cylinder actuated by the lever R. to
which it is connected by the rod Q₁ this plunger is preferably of a disc formation
to closely fit into the cylinder; the lever takes its bearing upon the sides of the
cistern somewhat farther from the pull down end than is ordinarily the case, as
shewn so as to afford the required leverage, the end (internally) of the lever is
provided with a weight R¹ to counterpoise the same when in action.
OPERATION.
When the cistern is charged the water will rise to a common levél in the
syphon G as also within and over the cylinder L. by now depressing the' lever R.
the plunger Q is forced down into. the aforesaid cylinder as far as the metal rim or
ledge therein P. this action causes the water in same to be forced down and
through the water way to syphon pipe G. up which it rises and so causes the water
in the said syphon to be forced to a higher level than before it was disturbed so
that when the water reaches the bend of the syphon the displacement of the
confined air contained therein produces a vacuum or partial vacuum within the
syphon and thus starts the initial flushing by setting up the syphonic action which
continues to suck up the water from the cistern through the lower chamber J, the
water rushing with velocity up the pipe G. and down the pipe F. of the syphon to
the pan or other receptacle to be flushed until the whole of the water in the cistern
has been exhausted, the cistern then refills in the usual manner by the action of
the ball valve and float.
Immediately the syphonage cominences the inrush of water to the syphon
causes the aforesaid loose disc O' to rise up the column or guide O. to its top; and
to the underside of the circular rim or ledge P. and so seals the water way
existing between the lower chamber and cylinder thus producing true syphonage
by confining the air to the bottom of the chamber; the plunger & meanwhile rises
to its normal position, the counterpoising weight R¹ upon the lever R effecting
this result as it obviously tends to depress the end of same, see Figure 1.
When the disc is at bottom of chamber it seals the water ways therein so that
the water may be forced up the syphon as otherwise it would run through the
perforated base plate of chamber.
The water as it charges the cistern after each flushing flows into the cylinder
and the loose disc O¹ descends to its original position after having risen to the top
of the column or guide as previously described.
By the herein described improvements a rapid powerful and practically silent
syphonic action is provided which when once set up cannot fail and enables the
cistern to be completely drained of its contents, without any likelihood of the
syphonage ceasing until this is accomplished. We wish it to be understood that

page_text: we do not necessarily limit ourselves to .the exact details of construction or
arrangement of parts as herein more particularly set forth provided that the
essential features of this our invention be retained..
