IMPROVEMENTS IN WATER CLOSET AND URINAL PANS OR BASINS
Year: 1885

page_text: I, JOB DEELEY of Fordrough Street Birmingham in the County of Warwick,
Manufacturer, do hereby declare the nature of said invention for "IMPROVEMENTS
IN WATER CLOSET AND URINAL PANS OR BASINS," to be as follows:-
Water closet and urinal pans or basins of the ordinary construction are so
arranged, that no provision is made for holding back a portion of the water or
flush, which has been previously used for the washing away of the soil, and for
the sealing of the joint. Thus it is necessary that a stratum or layer of water
should lie at the bottom of the pan or basin for the purpose of forming a sanitary
trap both in wash out basins and pan basins.
In pneumatic and other flushers, the water poured into the basin in removing
the soil acquires such a velocity that little or no water is left behind to form the
seal, or to cover the bottom of the pan, which is desirable; and the object of my
said invention is to remedy this defect by holding back a small portion of the flush,
sufficient to make an after flush which latter is allowed to slowly pass into the pan
after the soil has been removed.
I will describe my invention in connection with a wash out basin or pan.
Situated at the back of the basin or pan is an after flush or reserve chamber,
which is in communication with the socket or inlet passage leading to the pan.
This reserve chamber is of sufficient internal capacity to contain the requisite after
flush which is allowed to slowly pass therefrom to the pan through a small hole or
passage which is situated above the water level in the basin; that is, the after flush
or reserve chamber is preferably placed under the basin neck which is in communi-
cation with the down pipe leading from the flushing cistern. The entrance from
the inlet pipe is preferably near the walls of the pan, so that in the water passing
to the pan from the down pipe, it has to pass over the passage leading to the after
Bush chamber which is necessarily filled with water. This chamber is situated at
a level above the required height of water to be in the pan. Thus on the flushing
of the pan, the reserve or after flush chamber is filled, and the remainder of the
flush washes away the soil. The water thus stored up in the reserve chamber now
trickles or passes through the holes or aperture into the bottom of the basin or pan.

and communication with the down pipe may be made in any convenient way.
The after flush or reserve chamber may be situated above the inlet passage to
the basin instead of below, so that the column of water in the down pipe, raises
some of the water to a higher level' than the pan itself, and is there stored until the
flush is over, when it is allowed to slowly pass therefrom, by any suitable passage
or means; and although I have described that the after flush chamber is formed or
made with the pan, yet the said reserve chamber may be made separate from the
pan and connected thereto by any suitable means.
My improvements are applicable or can be applied to valve closets, pan and other
closets and urinals.

page_text: Improvements in Water Closet and Urinal Pans or Basins.
I, JOB DEELEY of Fordrough Street Birmingham in the County of Warwick
Manufacturer, do hereby declare the nature of said invention for "IMPROVEMENTS
IN WATER CLOSET AND URINAL PANS OR BASINS," and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:―
Water closet and urinal pans or basins of the ordinary construction are so
arranged, that no provision is made for holding back a portion of the water or
flush, which has been previously used for the washing away of the soil, and for the
sealing of the joint. Thus it is necessary that a stratum or layer of water should
lie at the bottom of the pan or basin for the purpose of forming a sanitary trap.
both in wash out basins and pan basins.
In pneumatic and other flushers, the water poured into the basin in removing
the soil, acquires such a velocity that little or no water is left behind to form the
seal, or to cover the bottom of the pan, which is desirable; and the object of my
said invention is to remedy this defect by holding back a small portion of the flush,
sufficient to make an after flush which latter is allowed to slowly pass into the pan
after the soil has been removed.
I will describe my invention in connection with a wash out basin or pan.
Situated at the back of the basin or pan is an after flush or reserve chamber,
which is in communication with the socket or inlet passage leading to the pan―
This reserve chamber is of sufficient internal capacity to contain the requisite after
flush which is allowed to slowly pass therefrom to the pan through a small hole or
passage which is situated above the water level in the basin; that is, the after
flush or reserve chamber is preferably placed under the basin neck which is in
communication with the down-pipe leading from the flushing cistern-The entrance
from the inlet pipe is preferably near the walls of the pan, so, that on the water
passing to the pan from the downpipe, it has to pass over the passage leading to
the after flush chamber which is necessarily filled with water-This chamber is
situated at a level above the required height of water to be in the pan-Thus on
the flushing of the pan, the reserve or after flush chamber is filled, and the
remainder of the flush washes away the soil-The water thus stored up in
the reserve chamber now trickles or passes through the holes or aperture into
the bottom of the basin or pan..
The after flush chamber may be placed in the pan or outside of the pan, and
communication with the downpipe may be made in any convenient way.
The after flush or reserve chamber may be situated above the inlet passage to
the basin instead of below, so that the column of water in the downpipe, raises
some of the water to a higher level than the pan itself and is there stored until the
flush is, over, when it is allowed to slowly pass therefrom, by any suitable passage
or means, and although I have described that the after flush chamber is formed or
11

pan and connected thereto by any suitable means.
My improvements are applicable or can be applied to valve closets, pan and
other closets and urinals.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which the same is to be performed.
Figure 1 represents in vertical section a sanitary pan or basin provided with an
after flush chamber or receptacle constructed according to my invention, by which
means sufficient water is held back from the main flush to cover the bottom of the
pan after the flushing is over-Figure 2 is a back view of the same, and figure 3 is
a part horizontal section showing the outlet passage to the pan, and also the inlet
passage to the after flush chamber.
The same letters of reference indicate corresponding parts in the several figures
of the Drawings.
a is the pan, a' the dished or concaved bottom, wherein a stratum of water rests,
for the purpose of covering the soil and thereby sealing or preventing odour arising
therefrom-b is the outlet neck leading to the soil pipe, and c is the after flush
chamber situated at the back of the outside of the basin, and under the inlet
neck dis a small hole or passage near the bottom of the back of the pan,
through which the water from the after flush chamber passes and flows into the
bottom of the basin where it there rests and forms a stratum of water of sufficient
depth to cover deposited soil-e is a depending lip overhanging the inlet or
entrance to the pan, and c³ is the mouth or inlet to the after flush chamber c.
On the flushing of the pan, the chamber c becomes filled, in consequence of the
water passing through the pipe, having to pass over the mouth or entrance to the
chamber, which said chamber thereby becomes filled, leaving the remainder of
the water to swill away the soil-The amount of water thus stored up, is sufficient
to cover the bottom of the pan.
After the flushing operation, the water thus stored up or held back in the
chamber c, slowly passes or trickles through the hole c³ into the bottom of the basin
as represented in figure 1.
Figure 4 represents my improvement applied to another form of sanitary pan in
which a pan and trap is made in one piece a is the basin, b the outlet pipe
leading to the trap e, and e³ the soil pipe neck of the said trap-d is the neck of
the basin, and f is the trap ventilator, while g is the basin ventilator.
Figure 5 shows another arrangement where the after-flush chamber is removed
from the basin-c is the after flush chamber, b is a pipe leading to or connected to
the neck d of the pan figures 1 and 4-6 is an upright portion of the said pipe
extending with its open mouth nearly to the inside top of the chamber c—6³ is an
inlet or downpipe leading from the flushing cistern g; so that on water passing
into the pan of a closet, a portion of it is intercepted and held back in the
after flush chamber, and afterwards allowed to slowly give itself out through the
hole e³.
The after flush chamber c and pipe 6 6' are made either in glazed earthenware,
lead or other suitable material. .
Figure 6 shows another form in which the after flush chamber is upon the side
of a flush pipe leading to the basin, the connection of which said pipe is effected by
socket ends.
Figure 7 represents an after flush chamber which can be applied to existing
basins, or basins not provided with after flush chambers-This chamber or
appliance a is situated above the neck d of an ordinary pan with its outlet a³
passing into the said neck of a pan or basin a, the joint or neck is made sound by
any suitable means-This chamber is divided into two parts, viz, a flush channel a³,
and an after flush compartment c, which latter has an inlet c³, and at its bottom
a small hole or outlet c³. The open mouth or top a* of the appliance, is in com-
munication with the downpipe of a cistern or flusher,

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. Combining or forming with a sanitary pan or basin for water closets and
for other similar purposes, an after flush chamber; consisting of a supplementary
water chamber or vessel, which keeps back, or stores up for a time, a portion of the
main flush, which is afterwards allowed to slowly pass therefrom, through a small
hole leading into the pan, substantially as described and illustrated in figures 1-2-
3 and 4 of the Drawings.
Secondly. Forming in flush or inlet passages of sanitary basins or pans, a catch
vessel or after flush chamber, substantially as described and set forth in figures 5
and 6 of the Drawings.
Thirdly. An after flush chamber made separate or formed independent of a
sanitary pan, or down pipe (leading to the pan of a flushing apparatus) and con-
sisting of a body a flush channel a' a' neck and outlet a³ after flush chamber c and
inlet and outlets c³ ³ substantially as described and set forth in figure 7.
