Improvements in Flush-out Water Closets and Flushing Apparatus.
We, ALFRED JOHNSON and FREDERICK GEORGE JOHNSON, both of Trent Sanitary

Works, Hanley, in the County of Stafford, Potters, and JOHN
HINCHLIFFE, of Trent Sanitary Works, Hanley, Manager, do hereby declare the
nature of our said invention to be as follows:-
Our said invention consists of a semi-porcelain or earthenware water-closet
which creates syphonic action when started by the ordinary flushing apparatus,
and which, whilst thus producing a more effective flushing action dispenses with
the usual metal or earthenware traps or bends. A further feature of our inven-
tion is a self-starting after-flush, which operates when slops or like matter are
emptied into the basin of the closet, and thereby ensures of the closet being
always kept supplied with clean water, instead of the slops being allowed to stand
through carelessness or other causes and which automatically syphons or empties
itself and refills to the normal depth of water seal.
In accordance with our said invention we form the waste outlet of the closet
high up at the rear side, directly beneath the usual flush inlet, and in front of
such opening and extending down into the basin we provide a special "lip" or
seal."
partition, which in conjunction with the wall of the basin forms a trap or
Said "lip" is hollow, and communicates with the usual flush or service pipe as
well as the usual fan or flushing ledge in the closet basin, and near the lower
and trap side of such lip is an auxiliary flushing aperture, directed in an angular
direction towards the top of the trap or waste outlet.
When the closet is flushed in the ordinary manner the water is directed partly
into the basin and partly through the said auxiliary aperture, and being directed
towards the said outlet, assists in displacing the contents of the closet, and, in
forcing the water over the bend, starts a syphonic action, between the closet basin
and the drain outlet.
In the opposite basin-wall part of said "trap" we form another opening, com-
municating with a secondary service pipe, supplied with water from an auxiliary
syphon in the ordinary cistern or other source. By the disposition of the said
opening a slight pressure is put upon the air in the said after-flush pipe, and
consequently when liquid slops or like matter are placed in the closet basin their
volume, added to the usual body of water in the basin, serves to start the afore-
said syphonic action in the bend or trap, and thus emptying the basin induce the
air under compression to travel down the secondary pipe and bringing with, or
after it the supply of water from the auxiliary syphon, thus bring up the water
in the water closet basin, to normal or predetermined area and seal without
requiring special manipulation as heretofore necessary.

We, ALFRED JOHNSON and FREDERICK GEORGE JOHNSON, both of Trent Sanitary
Works, Hanley, in the County of Stafford, Potters, and JOHN STRINGER
HINCHILIFFE, of Trent Sanitary Works, Hanley, Manager, 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; -.
Our said invention consists of a semi-porcelain or earthenware water-closet
which creates syphonic action when started by the ordinary flushing apparatus,
and which, whilst thus producing a more effective flushing action dispenses with
the usual metal or earthenware traps or bends. A further feature of our inven-
tion is a self-starting after-flush which may be used in any form of flushing
apparatus which operates when slops or like matter are emptied into the basin
of the closet, and thereby ensures of the closet being always kept supplied with
clean water instead of the slops being allowed to stand through carelessness or
other causes and which automatically syphons or empties itself and refills to the
normal depth of water seal.
And in order that our said invention may be more readily understood and
carried into practical effect we have hereunto annexed two sheets of drawings and
will now proceed to describe the same with the various figures and letters of
reference marked thereon.
Fig. 1 represents in section a closet and cistern arranged and constructed in
accordance with our invention. Fig. 2 illustrates a modification.
Figs. 3 and 4 illustrates in front section and sectional elevation the application
of our invention to a series of closets supplied from one cistern.
In accordance with our said invention we form the waste outlet (A) of the
closet high up at the rear side, directly beneath the usual flush inlet, and in front
of such opening and extending down into the basin (B) we provide a special lip
or partition (C) which in conjunction with the wall of the basin forms a trap
or seal. Said lip is hollow as illustrated and communicates with the usual flush
or service pipe (1)) as well as at the usual fan or flushing ledge (E) and near the
lower and trap side of such lip is a flushing aperture (F) directed in an angular
direction towards the top of the trap or waste outlet (A). In the bottom of the
basin we form another flushing aperture (G)..
When the closet (B) is flushed the flushing water is directed partly into the
basin (B) through rim or ledge (E), partly through aperture (F) and partly
through aperture (G) and in the case of apertare (F) directed towards the said
outlet (A) assists in displacing the contents of the closet, and forcing the water
over the bend, starts a syphonic action in the outlet (A) which serves to empty
the closet.
In the same trap outlet we form another opening (H) communicating with a
secondary service pipe (1) supplied with water from an auxiliary syphon (J) in
the ordinary cistern or other source. By the disposition of the said opening (H)
below the level of the water seal in the basin a slight pressure is put upon the
air in the said secondary service pipe (I), and the purpose of such pressure or
compression is that when liquid slops or like matters are emptied into the closet
basin, their volume, added to the usual body of water in the basin serves to
flood the trap, start a syphonic action in the outlet (A), and emptying the
basin (B) reduce the pressure on the air in pipes (I), which being followed by the
rise of water in syphon (J) starts an after-flush down the pipe, which serves to
automatically reseal the trap and bring up the water in the water closet basin to
the normal level or predetermined area.
:

page_text: To ensure of there always being sufficient water for the after-flush, we prefer
the construction of cistern in Fig. 1 in which that part of the cistern containing
the after-flush syphon is supplied with water before the other part, the water from
inlet (K) first flowing into part (L) communicating through passage (M) with
part (N), and from thence through overflow (0) into part (1) containing main
flushing syphon (Q).
In the application of our invention to a series of closets supplied with water
from a cistern common to all, as shewn in Fig. 3 we construct each closet in the
manner shewn in Fig. 1, but by preference, without the apertures (F) and (G)
and connect the after-flush pipe (I) to the soil pipe (R). One after-flush pipe
serves for all, and the air vent pipe commonly used and joined to bend (S) is,
by preference dispensed with so as to ensure of the syphonic action being con-
tinued until all the contents of the pipe (R) are completely ejected, the reseal-
ing of the trap being effected by the said after-flush from syphon (J) in lieu of
being resealed by the contaminated water which heretofore flowed back from the
bend (S).
In some applications of our invention the secondary syphon may be, in a small
vessel or cistern near the closet as shewn in Fig. 2 supplied with water from any
convenient source under control of a ball float."
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it to be
understood that we do not confine ourselves to the precise details, relative pro-
portions or dimensions of our improved flushing apparatus, and what we
claim is:-
1: In a water closet and the like, the combination with the basin of a hollow
"lip" or partition, an outlet trap of which said lip forms part, a jet aperture in
said lip, the main flushing pipe connecting with said lip, a pipe or passage ter-
minating in an aperture in the floor of the basin and supplied with water from
the main flush, a further and after-flush aperture in the outlet trap, or below the
water seal, and an after-flush supply pipe, syphon and cistern, all mounted and
operating, as and for the purposes set forth.
2:-In flushing devices for water closets and the like, an after-flush aperture
below the water seal or within the outlet trap, an after-flush pipe communicating
with such aperture and an auxiliary syphon (and cistern) communicating with
the said pipe, the relation of the said parts being such that the air in the said
after-flush pipe is under compression when the closet trap is sealed and released
of all compression or induced downwards when the closet is flushed by the main
flush, as set forth.
3: In a series of water closets flushed from a single cistern common to all,
an auxiliary cistern and syphon, and an after-flush pipe connected to the usual
soil pipe, substantially as set forth.
Dated this 10th day of May you.
