Water-closets.

Foreign Patent Solicitors, 6, Lord Street Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object to enable the liquid contents of water closets to
pass away into the waste pipe in the case of a stoppage taking place in the closet
funnel and consequently to prevent the closet basin overflowing and thus avoid the
room in which it is placed being flooded, which latter often takes place with the
closets at present employed owing to the flushing water running into the water
joint or trap when the tap for supplying water to the cistern is left open.
In this improved device, the water running from the cistern into the closet flows,
when a stoppage takes place, into a siphon-like side pipe, which connects below with
the waste pipe of the water joint or trap.
The cistern overflow pipe is in this case connected with a horizontal pipe which
is connected to the side of the closet, and should the float of the flushing cistern
cease to act at any time, this overflow pipe discharges its contents into the overflow
pipe of the pan, and into a side water waste tube, arranged close to the main water
joint or trap.
This second water passage opens into the main waste pipe somewhat higher than
the ordinary water level of the main water joint or trap.
As the side waste tube can be arranged either on the left or right side of the
main water joint or trap, the ventilating pipe may be alternately arranged, the tube
which connects the latter with the closet is attached to an intermediate piece, which
is placed over the main water joint or trap, and on which the actual closet basin or
pan rests.
By rotating the intermediate piece any position may be provided for.
The tube which is connected to the side of the closet opens into 'the intermediate
piece in such a way that its botton lies somewhat higher than the highest slot of
the strainer which covers the opening.
Under ordinary circumstances as herein before indicated the flushing water flows
through a pipe to the main or side water trap. The ventilation takes place through
the ventilating pipe. Now by this invention if the main water joint or trap
becomes stopped, the liquid rises above the overflow point, and any floating paper
or the like raised above the strainer as the level of the pipe which is connected
to the side of the closet is higher, so that no stoppage of the strainer can take
place. The rising liquid then pours through the last mentioned pipe into the side
waste pipe aforementioned, which conducts it to the main waste pipe. No over-
flowing of the water into the room in which the closet is situated can thus any
longer take place. If this overflow device should by some mishap become choked,
a further safety overflow device is provided by means of a tube, which is connected
at a higher point with the pan of the closet.
The liquid then passes through this tube, into the cistern overflow pipe and
thence into the side waste tube. The vertical ventilating pipe is never affected.

page_text: In order that the water which evaporates from the side trap may be again
constantly replaced, a small pipe is arranged between the main water trap and this
side one and stands somewhat above the ordinary water level of the same. As
soon as the closet is flushed the water level rises in the main trap and thereby
some water is poured into the side trap and thus the water which has evaporated
is replaced.

Improved Device for Preventing the Overflowing of

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil 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 has for its object to enable the liquid contents of water closets to
pass away into the waste pipe in the case of a stoppage taking place in the closet
funnel and consequently to prevent the closet basin overflowing and thus avoid the
room in which it is placed being flooded, which latter-often takes place with the
closets at present employed owing to the flushing water running into the water
joint or trap when the tap for supplying water to the cistern is left open.
In this improved device, the water running from the cistern into the closet flows,
when a stoppage takes place, into a siphon-like side pipe, which connects below with
the waste pipe of the water joint or trap.
In the accompanying drawings,
Figure 1 is a plan view;
Figure 2 a partial section of this improved arrangement.
The cistern overflow pipe a is in this case connected with a horizontal pipe b
which is connected to the side of the closet, and should the float of the flushing
cistern cease to act at any time, this overflow pipe discharges its contents into the
overflow pipe of the pan, and into a side water waste tube c arranged close to the
main water joint or trap.
This second water passage opens into the main waste pipe at d somewhat higher
than the ordinary water level of the main water joint or trap in the discharge
pipe f
As the side waste tube c can be arranged either on the left or right side of the
main water joint or trap, the ventilating pipe may be alternately arranged, the
tube which connects the latter with the closet is attached to an intermediate
piece m which
placed over the main water joint or trap, and on which the actual
.closet basin or pau rests.
By rotating the intermediate piece m any position may be provided for.
The tube opens into the intermediate piece m in such a way that its bottom
lies somewhat higher than the highest slot of the strainer which covers the
opening g.
Under ordinary circumstances, as hereinbefore indicated, the flushing water flows
through the pipe a to the main or side water trap. The ventilation takes place
through the pipe b and the ventilating pipe v. Κοιν by this invention if the main
+

page_text: water joint or trap becomes stopped, the liquid rises above the overflow point g and
any floating paper or the like is raised above the strainer as the level of the pipe h
which is connected to the side of the closet is higher, so that no stoppage of the
strainer can take place. The rising liquid then pours through the last mentioned
pipe into the side waste pipe c aforementioned, which conducts it to the main
waste pipe f. No overflowing of the water into the room in which the closet is
situated can thus any longer take place. If this overflow device should by some
mishap become choked, a further safety overflow device is provided by means of a
tube u which is connected at a higher point with the pan of the closet.
The liquid then passes through this tube into the cistern overflow pipe a and
thence into the side waste tube c. The vertical ventilating pipe is never
affected.
In order that the water which evaporates from the side trap may be again
constantly replaced, a small piper is arranged between the main water trap and
this side one and stands somewhat above the ordinary water level of the same.
As soon as the closet is flushed the water level rises in the main trap and thereby
some water is poured into the side trap and thus the water which has evaporated
is replaced.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is-
1. An improved device for preventing the overflowing of water closets consisting
in arranging beside the main water joint or trap, a side water tube c and trap
opening into the waste pipe fat a somewhat higher level, which side pipe c is con-
nected with the bottom of the pan (by means of an overflow pipe & connected with
the ventilating pipe and if desired with another overflow pipe from near the summit
of the pan) in such a way that the overflow pipe lies somewhat higher than the
overflow opening g of the discharge or flush, which opening is provided with a
sieve, substantially as hereinbefore described and shown on the accompanying
drawing.
•
2. In the arrangement described in Claim 1, the insertion of an intermediate
piece m between the pan and the water joint or trap, into which intermediate
piece the overflow pipe opens with the object of allowing the device to be
used with any position of the ventilating pipes substantially as described and
illustrated.
