Improvements in and relating to Waste or Slop 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:-
The invention is designed to prevent large articles, such as salmon-tins, old shoes
and the like from being thrown down into the basins of waste water closets, and
which have a tendancy to make up the trap and drain.
In carrying out our invention, we contract the sides of the closet pedestal or
the extension pipe situated between the seat and the closet basin at any suitable
part, to the shape or contour of a quatrefoil or other similar figure, to reduce
the space or area inside the pedestal or extension pipe at the part of contraction,
to a corresponding shape or contour, as will intercept or prevent, say a ball
four inches in diameter from passing through any part of the contracted space of
the quatrefoil or similar figure.
The points or cusps of the quatrefoil (or similar figure) are preferably made to
gradually slope upwards finishing or terminating with the circular or oval shape
of the interior of the extension pipe or pedestal as the case may be.
In the pedestal or upper part of the extension pipe of a waste water closet
not having the contraction or quatrefoil, we form a kind of drip ledge projecting
inwards say about an inch or so around the interior to prevent the extension pipe
below the drip ledge from becoming soiled or furred by excreta or urine, which
must necessarily fall into the closet basin direct without touching the sides of the
extension pipe below the ledge.
It will be obvious that the only part that can be soiled or furred will be the
pedestal, or the upper part of the extension pipe (when no pedestal is used), and
such part being within easy reach from the seat is readily cleaned.
The next part of our invention relates to multiple closets, in which the continuous
range of basins or the like and longitudinal connections are situated below the closet
floor; each basin or the like having an extension pipe or pedestal fitting into the
socket of each respective basin, and projecting upwards through the floor, say
The improve-
eighteen inches or thereabouts for the reception of the closet seat.
ments in this part of our invention consist essentially in the combination with such
arrangement of multiple closets of two underground tipping vessels or automatic
flushing tanks, situated one at each end of such series of closets; the discharge
outlet being preferably in the middle of the series and made to communicate with
one trap and drain.

Improvements in and relating to Waste or Slop 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 is designed firstly to prevent large articles, such as salmon

page_text: tins, old shoes, and the like being thrown down into the basins of waste water
closets, and which have a tendancy to make up the trap and drain.
In carrying out our invention, we contract the sides of the closet pedestal or
the extension pipe situated between the seat and the closet basin at any suitable
part to the shape or contour of a quatrefoil or other similar figure, to reduce the
space or area inside the pedestal or extension pipe at the part of contraction to a
corresponding shape or contour, as will intercept or prevent, say a ball four inches
in diameter from passing through any part of the contracted space of the quatrefoil
or similar figure; but we do not bind ourselves to this dimension, it may be more
or less if desired.
The points or cusps of the quatrefoil (or similar figure) are preferably made to
gradually slope upwards finishing or terminating with the circular or oval shape of
the interior of the extension pipe or pedestal as the case may be.
The next part of our invention relates to multiple closets, in which the con-
tinuous range of basins or the like and longitudinal connections are situated
below the closet floor, each basin or the like having an extension pipe or pedestal
fitting into the socket of each respective basin, and projecting upwards through
the floor, say 18 inches or thereabouts for the reception of the closet seat.
The improvements in this part of our invention consist essentially in the com-
bination with such arrangement of multiple closets of two tipping vessels or
automatic flushing tanks situated one at each end of such series of closets, the
discharge outlet being preferably in or about the middle of the series, and made
to communicate with one trap and drain, or if desired there may be two or more
outlets.
In order that our said invention may be fully understood, and readily carried
into practical effect, we have appended the accompanying sheet of drawings.
Fig. 1 is a plan of the first part of our invention. A is the rim at the top
of the pedestal or extension pipe, which may be circular, oval or otherwise in
shape. B B B and B are the sides thereof, which slope or are contracted at
any desired part to the shape or contour of a quatrefoil or other similar figure, the
cusps of which C₁, C2, C3 and C are plainly shewn in the drawings.
It will be evident that whilst the inside area of the closet pedestal or extension
pipe is sufficiently large to freely permit of the falling excreta to pass through,
yet owing to the peculiar shape of the quatrefoil or similar figure, large articles
are effectually prevented from being thrown down and lodging in the closet basin
or trap, and the sides or slopes are less likely to be soiled than when sloped in the
usual way.
Fig. 2 is a longitudinal section of multiple closets arranged in accordance with
the next part of our invention. Three closets A' are shewn, but there may be
more or less in number.
B and C are two automatic tippers arranged one at
each end of such series of closets, with the discharge or outlet basin or stench
trap D preferably placed at or about the middle of the series, by which improved
combination and arrangement, the closets are more thoroughly flushed.
The tippers B and C are supplied with waste water from the dish stones E
and F, fixed at or about the level of the ground, and with slop water from
drain pipes G and H.
The outlet I of the stench trap D is so arranged as to be turned in any direction
to suit the drain.
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 slop water closets, making the pan, or pedestal, or extension pipe with
sloping sides terminating at any desired part in the form of a quatrefoil or similar
figure, substantially as hereinbefore described and illustrated in Fig. 1, for the
purpose set forth.
2. In multiple slop water closets, the combination of two tipping vessels or

page_text: automatic flushing tanks situated one at each end of the range or series of closets,
with basin or basins and outlet trap or traps and drain, arranged substantially as
described and illustrated in Fig. 2.
