Improvements in Waste Water Latrine Closets.
We, JOHN JOHNSTON GREEN and WILLIAM OATES, of the Firm of Oates and
Green, Limited, of Claremount, Halifax, in the County of York, Sanitary Engineers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to waste water or latrine closets where a pedestal seat is
employed, the primary object of the first part of our invention being to construct
the lower basin in such a manner as to permit the trap or outlet pipe to be set at
any angle or direction, and this we propose to effect by forming the outlet end of
the basin without flange but forming it so that it will enter into a flanged trap.
A grate or plug is also used to enable a cleaning instrument to be inserted for
cleaning out the trap when required.
The bottom basin of each pedestal or pan is made concave so as to contain a
little water but the pipe connecting the adjoining pedestal is made without the
concave part, such concave only being opposite the bottom of each pan.
Secondly. In connection with pedestal closets we propose to employ a flanged
shoot or hopper placed upon the top of the pedestal. We propose to make the pan
of smooth porcelain so as to permit of its being readily cleaned.

We, JOHN JOHNSTON GREEN and WILLIAM OATES, of the Firm of Oates and
Green, Limited, of Claremount, Halifax, in the County of York, Sanitary Engineers,
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 waste water or latrine closets, where a pedestal seat is
employed, the primary object of one part of our invention being to construct a
concave bottomed basin with an outlet in such a manner as to permit the connecting
trap or outlet pipe to be set at any angle or direction, and at the same time to
admit of easy access to the trap for inspection or cleaning, and this we propose to
effect by forming the outlet end of the basin clear of the basin and with or without
flange, but forming it so that it will enter direct into a trap. A grate or plug is
also used clear of the basin to give easy access for cleaning out the trap when
required.
In order that our improvements may be better understood, reference is made to
the accompanying sheets of drawings illustrative thereof, wherein Fig. 1 is cross
section of our improved waste water latrine closet, and Fig. 2 is plan view
of same.
A represents a pedestal seat connected with or without a rising pipe or pan B to
a lower basin C. The part D of the said hasin is made with or without a lower
flange so as to permit the outlet end of the said basin to enter into the upper part

page_text: of a flanged trap E; by this means the said trap can be set at any desired angle
as shewn in dotted lines in Fig. 2, consequently a direct connection can be made
from the trap to the main sewer. The basin C is also provided with a grate or
plug G for ready access to the trap for inspection and for the purpose of inserting
a cleaning instrument for cleaning out the trap when required."
The bottom of basin C of each pedestal closet is made concave as shewn at H
for containing a little water. I represents the tipper which as it becomes full rocks
upon the fulcrum a and empties itself into the bottom of the basin C, thus washing
away any excreta and other matter lodging in the bottom of the said basin.
The tipper is fed with water by a pipe from an ordinary sinkstone in a cottage
house, or the said tipper may be fed from a fall pipe or bath or from any other
suitable and convenient source.
In Fig. 1 we have shewn a concave bottomed basin lying intermediate of the
trap E and the tipper I and in many cases we shall adopt this method, one of such
arrangements being connected with each dwelling, but in waste water latrine closets
which are jointly used in factories, schools and small cottage dwellings, we propose
to adopt a series of pedestals with or without rising pipes or pans B as shewn in
Fig. 3, a concave bottomed basin being combined with each pedestal, but between
these concave bottomed basins we place an intermediate pipe J, one tipper I thus
serving for a series of closets, and also one trap E the whole of which arrangement
will be well understood, together with the action thereof without further
comment.
In Fig. 3 the tipper I is shewn on the ground level or lower; we would, however,
observe that the tipper may be overhead, as shewn in Fig. 4, or the pipes may be
flushed by an automatic syphon tank, or by other suitable means if found more
desirable.
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 :-
Firstly. In waste water closets, a basin C having a concave bottom H and an
access pipe D, arranged substantially as described and illustrated.
Secondly. In waste water latrine closets, the combination there with of a concave
bottomed basin with access pipe D as illustrated, such basin being formed with or
without a flanged outlet for fitting direct on to a trap, the whole being constructed
and combined substantially as shewn in Fig. 1.
Thirdly. In waste water latrine closets, the combination therewith of a concave
bottomed basin with access pipe D, the inlet end being connected direct to the
tipper basin, and the outlet end direct to the trap, substantially as illustrated in
Fig. 1.
Fourthly. In waste water latrine closets, the pedestals of which are opposite a
concave bottomed basin and arranged in a series, as shewn in Figs. 3 and 4, the
combination therewith of the access pipe D with or without bottom flange and
connected direct to trap E, all combined and arranged substantially as herein
described and illustrated in Figs. 3 and 4 and for the purposes set forth.
