Improvements in Water Closets.
I, BURTON RICHARD PHILLIPSON of 10 Lower Baggot Street, Dublin, Engineer, do
hereby declare the nature of this invention to be as follows
This invention relates to an improved description of water closet which is also
suitable for use as a slop sink It is provided with two water sealed traps in
The two water seals have an air space between thein which
is provided with a ventilation pipe carried to the open air or to some other convenient
and safe outlet
succession to each other
On the course of the said ventilation pipe a valve chamber is fixed and in the valve
chamber a valve is placed which under ordinary circumstances remains open, and
admits free transit of air from the space between the water seals to the open. From
the valve in the chamber, an attachment is fixed which closes the valve when the pull
or lever which operates the water supply is worked, that is to say, the air valve is
closed when the water service to the basin is let on. The result of this arrangement
is that when water is thrown into the basın from a pail or other vessel it passes
through the two water seals without unsyphoning either of them because the open
ventilation between the two seals prevents syphonage, but when water is sent into the
basin from the cistern or ordinary means of supply, by the action of the lever the air
valve is closed, the result of the closing is that when a certain quantity of water has
entered the basin, syphonage takes place and the basin is discharged. The arrange-
ment here described enables me to use and to discharge a basin which holds a
considerable depth of water, it also provides great security against the entry of sewer
gas through the basın as in event of its passing the lower seal the foul air is provided
with means of exit through the ventilation pipe which when the closet is at rest,
always remains open.
The second or upper seal being unusually deep, and retaining a large quantity of
water is extremely unlikely to become unsealed by evaporation.

Improvements in Water Closets.
I BURTON RICHARD PHILLIPSON of 10 Lower Baggot Street Dublin 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
This invention relates to an improved description of water closet which is also
suitable for use as a slop sink. It is provided with two water sealed traps having an
air space between them which is provided with a ventilation pipe carried to the open
air or to some other convenient and safe outlet
On the course of the said ventilation pipe a valve chamber is fixed and in the valve
chamber a valve is placed which under ordinary circumstances remains open and
permits free transit of air from the space between the water seals to the open.
From the pull or lever which operates the water supply of the closet I connect an
attachment which closes the valve. The result of this arrangement is that when water
is sent into the basin from the cistern syphonage takes place and the basin is discharged
but when water is sent into the basin by other means, as for instance from the
emptying of a pail no syphonage takes place because the open valve admitting air
prevents syphonic action,

page_text: The arrangement here described enables me to use and to discharge a basin which
holds a considerable depth of water, it also gives great security against the entry of
sewer gas through the basin as in event of its passing the lower seal the foul air is
provided with means of exit through the ventilation pipe which when the closet is at
rest always remains open The second or upper seal being of considerable depth
retains a large quantity of water and is therefore extremely unlikely to become
unsealed by evaporation In addition to the attachment which operates the valve I
in some cases fix from the pull or lever of the water-closet another attachment which
releases a latch or catch which is employed to hold down the water closet seat, the
seat being provided with spring-hinges weights or other means of raising itself 10 1
vertical position.
When the water-closet is about to used the seat is pressed down by hand and is
caught by a self acting catch which retains it in the horizontal position until the
water-closet is flushed, upon tho pull or lover being used to flush the closet the seat
is released and returns to the vertical position, by this arrangement the seat is hept
free from splashing upon its under side by the action of the water and the basin is
always left ready for use as a slop sink.
In the accompanying drawing A represents the basin B B the upper water seal
C the air space between water seals D the lower water seal E the outlet to soil pipo
or to drain, F. the valve chamber and valve with a portion of the ventilation pipe
leading from the valve chamber.
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
1st The use of a water-closet having two water-seals or traps with an air space
between them which air space is provided with an outlet for the purpose of ventilation
and to prevent syphonic action at all times except when the discharge of the basın
by syphonage is desired.
2nd. The use of a water-closet having two water seals or traps with an air space
between them that is controlled by a valve which is closed by the same action that
operates the flushing service.
3rd. The use for the discharge of water-closet basins or for other purposes of a
continuous tube or water way having upon its course two water seals or traps with
an air space between them which air space is provided with an outlet for ventilation
that when open prevents syphonic action and when closed permits it to take
place.
4th. The use upon a self-raising water-closet seat of an attachment which retains
it in position for use until its release is desired.
