PROVISIONAL SPECIFICATION.
Improvements in Flushing Apparatus, More Especially Adapted for
Flushing Urinals.
I WILLIAM DAVIES of 8 Richmond Terrace Breck Road Everton Liverpool in the
County of Lancaster Engineer do hereby declare the nature of this Invention to be
as follows:-
This Invention consists of certain improvements in apparatus for flushing urinals
for which Letters Patent were granted to me bearing date as of the 26th July 1888
No. 10842 and has for its object to simplify the construction of the said apparatus
whereby economy is obtained.
.
According to my present invention I dispense with one of the two vessels e e¹ and
also the syphon 6 described and illustrated in the Specification to the said Letters
Patent and I provide a single vessel in which is a float connected by a stem and rod
or like connections to the plug of a cock on the pipe by which flushing water is
supplied to the tipping vessel. In this float I insert a short pipe closed at the upper
end and of a suitable length from the bottom of the float to form the short leg of the
syphon. The water discharged from the tipping vessel passes through a pipe leading
to the urinal pan and from this pan another pipe leads direct to the aforesaid vessel
containing the float. Urine or other liquid entering the pan passes down this pipe
into the said vessel containing the float which float rises in the vessel as the liquid
accumulates. Through the bottom of the vessel passes a stand pipe forming the long
leg of the syphon which is in communication with the drain the upper open end of
which stand pipe extends upwards in the pipe in the float to a height regulated
according to the quantity of water required to be used at each flushing operation.
When the float rises by the accumulation of liquid in the chamber sufficiently to cause
it to open the cock in the water supply pipe to which it is attached a supply of water
will flow into the tipping vessel (if that be used) from which it will afterwards
discharge into the urinal pan and thence through the pipe leading therefrom into the
vessel containing the float. The float in the vessel will then rise and a portion of the
liquid is discharged down the stand pipe causing a partial vacuum thereby establishing
a syphon action by which the water will flow from the chamber to the drain until the
lower end of the pipe leading from the urinal pan to the chamber is uncovered where-
upon the syphon action will cease leaving a sufficient quantity of water in the bottom
of the vessel to dilute the urine afterwards introduced. As the water flows from the
vessel the float descends and closes the cock in the water supply pipe which cock will
remain closed until the float is again raised by the liquid accumulating sufficiently in
the vessel to cause the float to rise and open it whereupon the operations hereinbefore
described will be repeated. In the tipping vessel I may provide a pipe or passage to
allow a small quantity of water to pass down through the pan before the tipping vessel
is full enough to tip in order to dilute the urine and accelerate the flush when
in use.

Improvements in Flushing Apparatus, More Especially Adapted for
Flushing Urinals.
I WILLIAM DAVIES of 8 Richmond Terrace Breck Road Everton 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 :-
My Invention consists of certain improvements in apparatus for flushing urinals for
which Letters Patent were granted to me bearing date as of the 26th July 1888
No. 10842 and my present Invention has for its object to simplify and so cheapen the
construction of the said apparatus.
According to my present Invention which I will describe with reference to the
accompanying drawing 1 dispense with one of the two vessels e e² and also with the
syphon b described and illustrated in the Specification of the aforesaid Letters Patent
and I provide a single vessel e in which is a float G connected by a stem c and rod c²
or equivalent connection to the plug of a cock H in the pipe I by which flushing
water is conducted either directly to the urinal basin A or (as shown) to the tipping
vessel D as in the apparatus described in the Specification of the aforesaid Letters
Patent. In the tipping vessel D I provide a pipe or passage L to allow a small
quantity of water to pass down into the urinal basin before the tipping vessel is
sufficiently full to cause it to tip to effect the flushing.
In the bottom of the float GI insert a short pipe K closed at its upper end and of
suitable length from the bottom of the float to form the short leg of a syphon
the long leg of the syphon being formed by the stand pipe 2 the upper end of
which passes through the bottom of the vessel e into the pipe K to a height regulated
according to the quantity of water required to be used at each flushing operation.
The lower end of the pipe f2 communicated with the drain or other place where
the waste liquid is received. Urine or other liquid entering the basin A passes
down the pipe F into the vessel e and as the liquid accumulates in this vessel the
float G will rise and through the stem c and rod c³ partly open the cock H thereby
admitting water into the tipping vessel D. This water overflowing the pipe L passes
down the pipe C into the urinal basin A and therefrom by the pipe F into the
vessel e thereby diluting the urine contained therein and causing the float G to rise
so as to further open the cock H. Water will then rapidly enter the tipping vessel D
and when it is sufficiently full to tip the vessel the water is discharged into the outer
vessel B and flows therefrom by the pipe C into the urinal basin and thence by the
pipe F into the vessel e the urinal pan being thus efficiently flushed. When the tipping
vessel D has discharged its contents it immediately rights itself and the water
discharged therefrom having entered the vessel e causes the float G to further rise
and fully open the cock H water from the pipe I entering the tipping vessel D which
becomes partially filled ready for the next operation whilst at the same time a portion
of the liquid from the vessel e entering the stand pipe causes a partial vacuum
thereby establishing a syphon action by which the liquid contained in the vessel e is
discharged through the stand pipe into the drain. The float G descends with the
water as it flows from the vessel e thereby effecting the closing. of the cock H and
when sufficient water has passed from the vessel to cause the mouth of the pipe K to
be uncovered the syphon action will cease leaving a sufficient quantity of water in the
bottom of the vessel e to dilute the urine afterwards introduced. The parts remain
in this position until the urinal is again used whereupon the operation herein before
described will be repeated.
In places where it is not convenient to employ the tipping vessel D and outer
vessel B they may be dispensed with and the water supply pipe I be made to com-
municate directly with the urinal basin as shown by dotted lines at i but it is
preferable to employ the tipping vessel where practicable as a more perfect flushing
is thereby effected owing to the greater body of water discharged into the basin A.

page_text: Although I have described my Invention as applied to the flushing of urinals it is
obvious that it is applicable for flushing scullery sinks and other places.
Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First-The general combination and arrangement of parts constituting an auto-
matic flushing apparatus for urinals and other places substantially as hereinbefore
described and illustrated by the accompanying drawing.
SecondIn flushing apparatus for urinals and other places a vessel arranged
below the urinal basin or the like and having a discharge pipe constituting a long
leg of a syphon the short leg of the syphon being in a float contained in the vessel
and connected to the supply cock to effect the Bushing of the urinal or the like
substantially in the manner herein before described with reference to the accompanying
drawing.
Third-In flushing apparatus for urinals and other places a tipping vessel arranged
above the urinal or the like and having a discharge pipe or passage through which
a small quantity of water passes to the urinal basin or the like before the complete
flushing takes place substantially as and for the purpose hereinbefore described with
reference to the accompanying drawing.
