The invention relates to improvements the object of which is to effect an
automatic flushing out action by means of syphon arrangements in connection with
a supply cistern, the apparatus being of the kind known as the automatic flush out
syphon cistern.
The improvements consist of the following arrangements; a supply or service
cistern receives a supply of water from a ball-tap or other suitable source, the
speed of entry of such supply of water being regulated according to circumstances.
Through the bottom of the supply or service cistern there passes the longer leg of a
flushing syphon so formed and proportioned as to take the shape of the well known
vena-contracta nozzle. The shorter leg of this syphon may be formed of a dome
or inverted cup like cover placed over the upper open ond of the said longer leg of
the syphon which stands up in the cistern, or the said shorter leg may be con-
structed in relation to the longer one in any other suitable way according to
circumstances. The lower end of the longer leg of the syphon passes down into an
LD021

page_text: S shaped trap or syphon fixed to or formed with the bottom of the supply or
service cistern. This trap is furnished with a smaller internal starting syphon, the
shorter leg of which passes down into the liquid at the bottom of the trap, and the
longer leg into the down pipe leading from the said trap. The top of this small
syphon is by preference somewhat contracted and oval in section while the orifices
of the two legs are expanded and are circular in section. A small stand pipe is
connected at its lower end with the trap and is carried up in the supply cistern to
a height about equal to that to which the water in such cistern is intended to rise
before the apparatus is started in action. The said stand pipe may be bell mouthed
at the top.
The action of the apparatus is as follows.
Water is allowed to run slowly or to dribble into the supply tank; as soon
as it has risen therein as far as the upper edge of the aforesaid longer leg of
the flushing syphon it begins to overflow through such leg into the trap below, and
when the latter is filled up to the lower end of the said longer leg, the air in the
dome, cap, or other upper part of the flushing syphon begins to be compressed therein
between such upper part of the syphon and the water in the trap; this stops for a
time the flow of water down the longer leg of the flushing syphon into the trap
and consequently the level of the water in the supply tank rises above the dome,
cap, or other upper part of the flushing cistern until it reaches the upper edge of
the aforesaid stand pipe. It then beads up above the said edge and suddenly flows
with a rush down the stand pipe into the trap. This sudden rush of water into
the trap raises the level of the water therein till it fills the starting syphon which
then begins to net, dragging the water almost instantaneously out of the trap; the
compressed air in the flushing syphon is thus liberated, and the head of water
above the top of the latter fills the longer leg and starts that syphon in action,
effecting the flush which continues until the descent of the level of the water in the
supply cistern uncovers_the_short-end-of the flushing syplion, when-the-action-

JOSEPH JOHN TYLOR, of 2 Newgate Street, in the City of London, Brass
Founder. "IMPROVEMENTS IN APPARATUS AND ARRANGEMENTS FOR THE WATER-

The invention relates to improvements, the object of which is to effect an
automatic flushing-out action, by means of syphon arrangements in connection
with a supply cistern, the apparatus being of the kind known as the automatic
flush-out syphon cistern.
The improvements consist of the following arrangements:
A supply or service cistern A (see Figure 1 of the drawings hereto annexed)
receives a supply of water from a ball-tap, ordinary cock, or other suitable source;
the speed of entry of such supply of water being regulated according to circum-
stances. Through the bottom of the supply or service cistern A there passes the
longer leg B of a flushing syphon so formed and proportioned as to take the shape
of the well known vena-contracta nozzle. The shorter leg of this syphon may be
formed of a dome or inverted cup-like cover C, placed over the upper open end of
the said longer leg B of the syphon which stands up in the cistern, or the said
shorter leg may be constructed in relation to the longer one in any other suitable
way according to circumstances; for example it may be formed as the leg of a bent
syphon as shown in dotted lines in the Figure. The lower end of the longer leg B
of the syphon passes down into an S shaped trap or syphon D fixed to or formed
with the bottom of the supply or service cistern A. This trap D is furnished with
a smaller internal starting syphon E the shorter leg of which passes down into
the liquid at the bottom of the trap D, and the longer leg into the down pipe F
leading from the said trap. This small syphon E is by preference somewhat
contracted and oval in section at the top, while the orifices of the two legs may be
expanded into the circular form but it may be either circular or elliptic throughout.
A small stand pipe G is connected at its lower end with the trap D, and is carried
up in the supply cistern A to a height about equal to that to which the water in
the cistern A is intended to rise before the apparatus is started in action. The
said stand pipe G may preferably be bell-mouthed at the top as shown.
The action of the apparatus is as follows:-
Water is allowed to run slowly or to dribble into the supply cistern A; as soon
as it has risen therein as far as the upper edge of the aforesaid longer leg B of the
flushing syphon it begins to overflow through such leg B into the trap D below,
and when the latter is filled up to the lower end of the said longer leg B, the air in
the dome, cap, or other upper part C of the flushing syphon begins to be compressed
therein between such upper part of the syphon and the water in the trap; this
stops for a time the flow of water down the longer leg B of the flushing syphon
into the trap D, and consequently the level of the water in the supply cistern A
rises above the dome, cap, or other upper part C of the flushing syphon until it
reaches the upper edge of the aforesaid stand pipe G. It then beads up above the
said edge and suddenly flows with a rush down the stand pipe G into the trap D.

page_text: and 4.
Figure 5 shows a syphon closet constructed with the longer arm B of its syphon
in the form of a venu-contracta similar to the longer arm B of the flushing syphon
in Figure 1. When the measured quantity of flushing water is admitted into the
basin it overflows into the longer leg B of the syphon, the vena-contracta shape of
which facilitates the discharge of the air from such longer leg, and when that is
effected the syphon I, B, is started and the contents of the closet basin are quickly
drawn out down the leg B until the lip H of the trap D is uncovered when the
syphon action is broken, and the water contained in the leg I of the syphon flows
back into the basin and effects the trapping thereof until the next action. Figure 6
shows a closet with similar automatic syphoning arrangements but of somewhat
different form.
Having now described the nature of the said Invention, and the manner in
which the same is to or may be carried into effect, I would have it understood that
what I clain as the Invention to be secured by the within in part recited letters
patent is :-
First. In automatic syphon flush-out cisterns the combination of the flushing syphon,
the longer leg of which is formed as a vena-contracta with a secondary trap
or syphon over the edge of which is placed or formed a small starting
syphon, or the lip of which is formed, in the alternative, of a self-acting
sluice gate, and in connection with which trap is a stand pipe rising in the
cistern to about the level to which the liquid is intended to rise, the
whole combined and acting substantially as hereinbefore described, and
illustrated in Figures 1, 2, 3 and 4 of the drawings hereto annexed, and
for the purposes specified.

page_text: Second. In syphon closets the construction of the longer leg of the syphon in the
form of the vena-contracta as hereinbefore described and illustrated in
Figures 5 and 6 of the drawings.
In witness whereof, I, the said Joseph John Tylor have hereunto set my
hand and seal this tenth day of May in the year of our Lord One
thousand eight hundred and eighty three.
