Improvements in and relating to Water Closets.
We, JAMES DUCKETT and ALFRED DUCKETT of Mitre Brick Works, Burnley,
in the County of Lancaster, Brick and Sanitary Pipe Manufacturers, do hereby
declare the nature of this invention to be as follows:
This invention of improvements relates firstly to an arrangement and combination
of water closets with urinals at railway stations and other public places, in such a
manner, that the water used for flushing the urinal may be collected and utilized
for flushing adjoining water closets. For this purpose, the urinals may be con-
structed on the continuous or cradle system, and the water delivered into a kind of
trough placed against the wall and at a suitable distance from the floor, say about
2 feet more or less to ensure sufficient gravitation for the water from the cradle to
the flushing tanks of the closets, which are situated preferably above the floor line.
The waste water from the "cradle" may be conducted to the several closets
through a pipe or open channel, having √ shaped or other suitable branches, one
for each flushing tank.
The first branch is or may be more contracted than the next, and so on in
succession through the rest of the series, in order that a more equal distribution of
water may be discharged into the several flushing tanks, which are preferably con-
structed on the tilting principle, and discharge their contents automatically into the
closet basins.
To prevent the permanent adherence of excrement at the back of the pan or
basin of the closets, water may be conveyed from the open channel so as to gently
flow to wet the back of the basin or pan.
To provide against a flush taking place whilst a person is on the seat, the tank
The
may be locked by the depression of the seat or in any other suitable manner.
tilting tank may also be provided with a rod or other attachment which can be
readily seized by hand to overturn the tank immediately after the closet has been
used.
The closet basin and the box containing the tilting vessel are preferably con-
structed of one piece of glazed earthenware.
The next part of our invention relates to multiple closets, preferably arranged in
line and in close proximity to each other. The interior of the closet basins may be
of elliptical shape in horizontal section and terminates above in a circular socket
of about 12 inches or so in diameter, to receive an extension tube of the same
diameter, which connects the basin with the closet seat. This tube may be made to
incline forward in a similar manner and for the same purpose, as that described in
the Specification lodged by the said James Duckett and Alfred Duckett dated the
19th day of March 1890 No. 4273.
The basin from its centre to the inlet and outlet junctions is gradually contracted
to fit the socket of a pipe of about 6 inches in diameter, interposed between and
connecting together the adjoining closet basins, which may be arranged above or
below the floor line as may be found most convenient.
At or near the outlet end of the last basin of the series, we form a weir of
sufficient height as will retain in the tubular system a shallow sheet of water of about
an inch in depth.
The water is contracted in width in the tubular connections, but widens out in
the basin to its fullest width to receive excreta, and prevent its adherence to the
bottom of the closet basin.
The flushing arrangement is situated at the opposite end of the series of closet
basins to that of the weir, and may consist of a tilting tank, siphon or other

page_text: suitable arrangement, and which may flush automatically or otherwise as may be
desired.
We are aware that in multiple closet basins, hollows have been formed to retain
after each flush a shallow depth of water; but in our arrangement, an unbroken
slicet or stratum of water is maintained of one uniform depth throughout the series
of closet basins, and contracted tubular connections, which will ensure a stronger
and more efficient flush, that will effectually sweep away the excrement and water
from one basin to another in succession through the series of basins, and over the
weir into a trap below, and from thence to the main drain or sewer.
The trap is adjustable in a socket near the weir and can be turned in any direction
to suit the drain.
The next part of our present invention relates to further improvements in the
closet basin described in the Specification of the said James Duckett and Alfred
Duckett dated the 21st day of July 1889 No. 12126.
Instead of placing the outlet from the weir in the centre of the basin as described
in the said Specification, it may be placed to one side of the basin, and may be of
any suitable shape, but preferably semicircular in form, having on its edge a
projecting rib, the ends of which abut against the sides of the basin, and behind
which the water is held back to form the weir. By this arrangement, no place is
allowed for excrement to lodge in the weir or basin during the flush.
This part of our invention equally applicable to form the weir at the termina-
tion of the series of closet basins above described, as well as for separate or single
closets.

Improvements in and relating to Water Closets.
We,
JAMES DUCKETT and ALFRED DUCKETT, of Mitre Brick Works, Burnley,
in the County of Lancaster, Brick and Sanitary Pipe Manufacturers, 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 multiple closets preferably arranged in a line and in
close proximity to each other.
The interior of the closet basins may be of elliptical shape in horizontal section,
and terminates above in a circular socket of about twelve inches or so in diameter
to receive an extension tube of the same diameter which connects the basin with
the closet seat. This tube may be made to incline forwards in a similar manner
and for the same purpose as that described in the Specification lodged by the said
James Duckett and Alfred Duckett, dated the 19th day of March 1890, No. 4273.
The basin from its centre to the inlet and outlet junctions is gradually contracted
to fit the socket of a pipe of reduced capacity interposed between and connecting
together the adjoining closet basins, which may be arranged above or below the
floor-line of closets as may be found most convenient.
At or near the outlet end of the last basin of the series we form a weir of
sufficient height, as will retain in the tubular system a shallow sheet of water of
about an inch in depth.
The water is contracted in width in the tubular connections, but widens out in
the basin to its fullest width to receive excreta, and prevent its adherence to the
back and bottom of the closet basin.
The flushing arrangement is situated at the opposite end of the series of closet-
basins to that of the weir; and may consist of a tilting tank, siphon or other
suitable arrangement, and which may flush automatically or otherwise as may be
desired.

page_text: We are aware that in multiple closet basins hollows have been formed to retain
after each flush a shallow depth of water: but in our arrangement an unbroken
sheet or stratum of water is maintained of one uniform depth throughout the series
of closet basins and contracted tubular connections, which will ensure a stronger
and more efficient flush, that will effectually sweep away the excrement and water
from one basin to another in succession through the series of basins and over the
weir into a trap below, and from thence to the main drain.
The trap is adjustable in a socket near the weir, and can be turned in any
direction to suit the drain.
In the accompanying drawings, Figs. 1 and 2 are respectively end and side
elevations in section of an arrangement of multiple closets constructed in accordance
with our invention and with the closets situated below the floor line; Fig. 3 is a
sectional end elevation and Fig. 4a horizontal section of the same but with the
closet basins and contracted tubular connections laid on or near the floor-line.
A denotes the closet basins, and B and C the contracted tubular connections,
which may be circular or oval in section.
At the commencement of the series of closet basins is situated receptacle D, in
which is mounted a tipper or tilting tank E; whilst to the rear of the closet basins
is formed a weir F, which maintains a uniform and shallow depth or stratum of
water, throughout the series of closet-basins and tubular connections.
These con-
tracted connections, during the discharge of water from the tilting tank E, cause a
stronger and more efficient flush as will effectually sweep away excrement and
water from one basin to another in succession through the series of basins and
intervening contracted tubular connections over the weir into trap G, and from
thence to the main drain.
Above the trap G is a socket II, which is capable of turning in any direction on
the lower end of the circular outlet I from the weir F.
When the series of closet basins and contracted tubular connections are sunk
below the floor-line, as seen in Figs. 1 and 2, two extension pipes L and M may be
used as a connection between each basin and the closet seat; but in cases where
the series of basins are situated on or above the floor-line, as represented in Fig. 3,
a short extension pipe L may be used.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In multiple closets, the employment of contracted tubular connections inter-
posing between the closet basin, and having a uniform depth or stratum of water
throughout the system, substantially as described and illustrated.
2. The general arrangement and combination of the parts in multiple closets,
substantially as described and illustrated.
