PROVISIONAL SPECIFICATION.
Improvements in and relating to Syphon Cisterns and Water Waste
Preventers.
I, THOMAS SINGLETON, of, 25 Arthur Street, Small Heath, Birmingham, in the
County of Warwick, Fitter, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in syphon flushing cisterns, and water
waste preventers for use in w.c.'s, urinals and such like purposes where a syphon
cistern may be required. The cistern or tank may be constructed in the usual
manner, and fitted with the ordinary accessories as regards the general arrangement
of same.
My improvements consist in casting an outer cylinder or water jacket upon the
stand pipe & in one with the same; this outer cylinder or jacket which is open at
each end rises about three quarters of the height of the stand pipe and provides a
water way for the water to freely rise between it and the stand pipe.
The stand pipe (which is surrounded at its base by a suitable well or inner
chamber) is screwed into the bottom of the cistern in connection with the supply
pipe leading therefrom to the w.c. or urinal basin. A bell or dome works in the
usual way by means of lever and chain, over the stand pipe, and its cylindrical
attachment or jacket.
The action of depressing the lever raises the bell, its weight in descending into
the well, forces the water up the interior of the bell or dome, and inside and outside
of the cylinder or jacket on the stand pipe, and over the top of and down the stand
pipe, & thus flushing the basin; the inrush of water displacing the confined air
within the bell a vacuum is formed, and syphonic action started, whereby practically
the whole contents of the cistern are exhausted at each flushing, thus preventing
waste of water.
The cistern is charged again by the usual method, ready for next flushing.

COMPLETE SPECIFICATION.
Improvements in and relating to Syphon Cisterns and Water Waste
Preventers.
I, THOMAS SINGLETON of, 25, Arthur Street, Small Heath, Birmingham, in the
County of Warwick, 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 accompanying
tbis Specification and to the figures and letters shewn thereon:-
My invention relates to what are known as syphon flushing cisterns and water
waste preventers for use in w.c.'s, urinals and such like purposes, where a given
quantity of water is required for flushing and cleansing the same, and my object is
to provide improved means for obtaining a rapid syphonic action whereby the
contents of the cistern may be entirely discharged at each flushing and waste of
water prevented. In carrying out my invention I use the ordinary kind of cistern
[Price 8d.1

page_text: or tank having a syphon or standpipe and weighted bell or dome, the general
fittings of the cistern may be constructed and arranged in the usual manner for the
supply of water from the main service to the cistern and its delivery to the pan or
basin of the w.c. or urinal.
My improvements consist in the fact of casting an outer cylinder or water jacket
around and upon the syphon or stand pipe, which cylinder rises a certain height
from near the base of the syphon or stand pipe, and is open at each end in order to
provide a water way; within the cistern is a circular or other shaped well of the
required depth which is supported by means of feet, rests, or otherwise, upon the
Hoor of the cistern so that the water may have access to and flow between the floor
of the cistern and the floor of the well.
I will now proceed to describe my method with the assistance of the drawings in
which,
Figure 1, is a sectional elevation with the different parts in their normal position
and the cistern charged.
Figure 2. is a part sectional elevation shewing the weighted bell or dome
raised.
Figure 3. is an elevation of the syphon or stand pipe and water jacket thereon.
Figure 4. is a transverse section of the well, shewing the circular aperture
through which the syphon or stand pipe passes.
Similar letters of reference indicate similar parts on the figures.
Let A represent the cistern or tank of the ordinary or other suitable kind which
is supplied with water from the main service by the inlet pipe B regulated and
governed by the ball valve C and float D, overflow or outlet is provided for by
means of the pipe E.
The syphon or stand pipe F rises through the circular or other shaped well G
to nearly the same height as the cistern walls and considerably above high water
level and is screwed in at its base through the cistern floor to the junction of the
supply or flushing pipe H as in the usual way.
A cylindrical water jacket I is cast upon the syphon or stand pipe F as shewn by
means of snugs J, the said water jacket being open at each end K, K', to allow of
the passage of the water in its uprising, when the cistern is filling and when the
water is being forced up in action.
Upon the lower part or edge of the cylindrical water jacket I are.cast two or
more snugs or feet M, M', which are for the purpose of keeping the well G rigid
and in place with the syphon F and its water jacket I which is effected by reason
of the snugs obtaining a bearing upon or impinging the floor of the well so that
when the syphon pipe F is screwed up from the exterior of the cistern by the fly
nut N all the parts are made firm.
The weighted bell or dome O works piston like within the well G and over the
syphon or stand pipe F and water jacket I, the said bell being raised and lowered
by means of a lever P and chain Q or other suitable arrangement (lever, rod, or
other means) for picking up the bell, such lever, as shewn, obtains its bearing by
means of its axis in slots cut in the walls of the cistern.
The cistern as seen in its normal state in Figure 1 is full, or nearly so the
volume of water as the cistern is filling having also risen up the interior of the
bell or dome to a common level with that in the cistern, the water ways R, R',
beneath the well G and the water ways K, K', of the water jacket I allowing of the
free passage and uprising of the water within the said bell or dome O.
The operation of flushing is performed thus:-
By drawing down or otherwise actuating the chain (or other lever connection)
the lever is depressed and the weighted bell or dome raised to a certain height as
seen in Figure 2; by now releasing the chain the weighted bell descends into the
well, the water is obviously displaced by this action and in the first instance a
certain quantity is forced up the interior of the bell to a higher level than it has
hitherto occupied therein and over the top of and down the syphon or stand pipe
the water as it is forced to rise up the bell or dome (by its displacement in the

page_text: well and cistern) in turn displaces the confined air: thus creating a partial vacuum,
within the interior or crown of the bell and syphon or stand pipe, thus setting up.
the syphonic action and starting the initial flushing: this syphon action causes the
cistern to be rapidly emptied of its contents and the flushing of the w.c. or urinal is
effected. The cistern then refills in the usual manner by the action of the ball
valve and float, and is ready for the next flushing.
By the herein described improvements of a syphon pipe and water jacket com-
bined and arranged as shewn, the effect is to greatly facilitate the power of the
syphonic action, whereby the whole contents of the cistern is exhausted at each
flushing and waste of water prevented and at the same time the possibility is avoided
of the syphonage ceasing to act when once set up.
I wish it to be clearly understood that in describing the means to be employed
for carrying my invention into practical effect, I do not necessarily confine myself
to the precise formation and arrangement of parts constituting my improvements as.
I may vary or modify the same without any material departure from the principle
of my said invention.
Having now particularly described and ascertained the object and nature of my
said invention and in what manner the same is to be performed, I declare that what
I claim is
Firstly. In syphon flushing cisterns and water waste preventers, the particular
formation and arrangement of the syphon or stand pipe, the said syphon or stand
pipe having in combination therewith and cast thereon a cylinder or water jacket,.
with feet or snugs upon same, and having water ways, and operating in manner and
for the purpose substantially as herein more particularly set forth described and
illustrated.
Secondly. In syphon flushing cisterns and water waste preventers, the introduction
and general arrangement of the cylindrical water jacket cast upon or attached to
the syphon or stand pipe either alone or in combination with the remaining essential
working parts constituting a syphon cistern and acting in the manner (or in other
similar manner) set forth and described.
