PROVISIONAL SPECIFICATION.
Improvements in Flushing Apparatus, More Especially Adapted for
Flushing Urinals.
I WILLIAM DAVIES of Aubrey House Aubrey Street, Liverpool in the County of
Lancaster, Engineer do hereby declare the nature of this invention to be as
follows:
The object of my Invention is to provide a simple and efficient apparatus for
flushing urinals or the like places where urine or other liquid is discharged and
where it is desired to effect at intervals a flushing and cleansing of the urinal or
other place and the pipes and passages connected therewith.
According to my Invention (which I will describe as applied to a urinal) I
provide at a higher level than the pan of the urinal a device for supplying water
to the urinal consisting of a discharge pipe from a cistern or main or of a cistern or
vessel so hung that when a certain amount of water has been passed into it, it will
tip and discharge its contents into the pan of the urinal. At a lower level than
the pan of the urinal I provide a vessel having two compartments.
Into the first
compartment the urine from the pan passes by a pipe or the like. The urine passes
from the first compartiment by a pipe or passage into the second compartment in
which there is a float the rise and fall of which opens and closes a valve on the pipe
or device by which water is supplied to the pan of the urinal or to the tipping
cistern or vessel above. The second compartment leads to the drain or other place
of discharge by a discharge syphon. When a sufficient quantity of urine has passed
into the second compartment the float therein rises and opens the valve by which
water is supplied to the urinal pan direct or to the tipping cistern or vessel which
after a time tips over and discharges its contents down into the urinal pan so that
in either case flushing water is passed into the urinal pan from whence it passes
into the first and second compartments until it rises in the second compartment

page_text: above the bend of the discharge syphon when the water and urine passes off by the
said syphon into the drain pipe or the like until the level of the short leg of the
syphon is reached when the syphon action ceases. The water remaining in the first
compartment then flows by the pipe or passage aforesaid into the second compart-
ment leaving thus a sufficient quantity of water in the apparatus to dilute the urine 5
until the rise of the liquid level in the second compartment again causes a repetition
of the flushing.

Improvements in Flushing Apparatus, More Especially Adapted for

I WILLIAM DAVIES late of Aubrey House Aubrey Street but now of 8 Richmond
Terrace Breck Road both in Liverpool in the County of Lancaster Engineer 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:-
The object of my Invention is to provide a simple and efficient apparatus for
flushing urinals or the like places where urine or other liquid is discharged and
where it is desired to automatically effect by the urine voided or liquid discharged
a flushing and cleansing of the urinal or other place and the pipes and passages
connected therewith.

I will describe my Invention as applied to a urinal from which its application to
other purposes may be readily understood premising however that I do not restrict
myself to the precise details hereinafter described and illustrated. The accompanying
drawing illustrates in sectional elevation, flushing apparatus constructed and
arranged according to my Invention as applied to a urinal pan or basin. At a
higher level than the pan A of the urinal I provide a chamber B connected to the
pan A by a pipe C. In the interior of this chamber or in proximity thereto is a
cistern or vessel D-so hung or supported on pivots d that when a certain amount of
water has been passed into it, as hereinafter described it will tip and discharge its
contents into the chamber B the water passing thence through the pipe C into the
pan of the urinal. At a lower level than the pan of the urinal I provide a vessel E
having two compartments e e³ into the first compartment e of which vessel, the
urine passes from the pan A by a pipe For the like, and thence by a syphon pipe
or passage b from this compartment into the second compartment e. In the compart-
ment there is a float G connected by a rod c and arm to the plug of a cock or
valve H on the pipe I through which pipe water is supplied to the tipping cistern
or vessel D. When a sufficient quantity of urine or other liquid has passed into the
second compartiment the float G rises and opens the cock or valve H so as to
admit water to the tipping cistern or vessel D which vessel is so balanced on its
pivots that when a certain quantity of water has, entered it tips over and discharges
its contents into the chamber B the water passing thence down the pipe C into
the urinal pan whence it passes into the first and second compartments ee of the
vessel E. The second compartment leads by a discharge syphon ff' to the drain
or other place of discharge. When the liquid in the compartment e rises above
the bend of the discharge syphon ff a syphon action will be established so as to
discharge the water and urine by the said syphon into the drain or the like until
the mouth of the short leg of the syphon is uncovered when the syphon action
ceases. The water remaining in the compartment. e then flows by the syphon pipe
or passage 6 into the compartment leaving a sufficient quantity of water in the

page_text: apparatus to dilute the urine afterwards introduced, until the rise of the liquid level
in this compartment again causes a repetition of the flushing as hereinbefore
described. When the tipping vessel D has discharged its contents into the urinal
pan A the vessel will immediately resume its horizontal position. The water passing
from the pan A into the chambers e e causes the float G to rise and open the
cock or valve and thus admit a quantity of water to the vessel D, not sufficient
however to cause the vessel to tip, as at the same time the syphon action herein-
before described is established and the contents of the chamber is being
discharged, so that the float will lower and close the cock or valve before the
vessel D is fully charged. When the level of the liquid in the chamber e³ is raised
by the entrance therein of urine from the pan A, sufficient to cause the float G
to open the cock or valve H the vessel D will be fully charged so as to cause it
to tip and discharge its contents into the chamber B as hereinbefore described to
effect the flushing of the urinal.
It will thus be seen that the flushing is effected automatically by the accumulation
of urine and that if the urinal remains unused no water will be wasted by
unnecessary flushing, whilst there always remains sufficient water in the apparatus
to dilute the urine and prevent offensive smells.
Instead of charging a tipping vessel with water for flushing the urinal as herein-
before described the flushing water may be admitted directly into the pan A in
which case the discharge syphon should be so arranged as to discharge the
contents of the compartment faster than the water enters the pan A but I prefer
the arrangement hereinbefore described..
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
claim is.―
1. In apparatus for flushing urinals and the like the combination with a
discharge syphon arrangement of a vessel having two compartments arranged at a
level below that of the urinal pan or the like and into which the urine voided or
other liquid introduced into the pan passes and causes a float contained in one of
the compartments to rise and open a supply cock to effect the flushing of the
urinal or the like substantially as hereinbefore described.
2. In apparatus for flushing urinals and the like the combination with a
discharge syphon arrangement in a vessel containing two compartments arranged at
a level below the urinal pan or the like, of a tipping vessel arranged above the
urinal pan or the like and automatically supplied with water by the rising of a float
in one of the compartments of the lower vessel substantially in the manner and for
the purpose hereinbefore described with reference to the accompanying drawings.
3. In flushing apparatus for urinals and the like the vessel E having two compart-
ments communicating with each other by a syphon pipe so arranged as to ensure a
quantity of water being retained in the apparatus substantially as and for the purpose
hereinbefore described.
4. The general combination and arrangement of parts constituting an automatic
flushing apparatus for urinals and the like substantially as hereinbefore described
and illustrated by the accompanying drawings.
