COMPLETE SPECIFICATION.
Improvements in Waste or Slop Water Closets.
We, J. DUCKETT AND SON, LIMITED, Mitre Sanitary Works, Burnley, in the
County of Lancaster, and JAMES DUCKETT of Woodleigh, Burnley aforesaid,
Sanitary Ware Manufacturer, 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:-
The invention consists of improvements in and relating to slop water closets, and
in utilizing waste or slop water for the purpose of flushing closets in such a manner
as to minimise the possibility of soiling or fouling the pan or basin, which has not
previously been satisfactorily accomplished.
In order to shew clearly in various ways how we accomplish this, and to assist in
making our invention clearly understood, we annex a series of drawings (Figs. 1 to 8
inclusive) all of which refer to our improvement, which we designate a top-flushed
slop water closet to distinguish it from the ordinary forms of slop water closets,
which are bottom flushed, i.e. where the slop water is discharged into the closet at
a point below the floor level.
In the first part of our invention, we make a self-contained pedestal wash-down
slop-water closet in one piece of ware as indicated by Figs. 6, 7 and 8. Figs. 3
and 7 are plans of the first part of our invention, and Figs. 6 and 8 are sectional
elevations of the same. A is the basin. B is in the inlet for waste water from
sink, baths, roofs et cetera. C is the outlet to main drain. D is an annular channel
in basin. E is the S trap. The feed or slop water is conveyed to the closet by
drain pipes K above the floor level, instead of below it, as is usual with this class
of closet, and enters inlet B, (see Figs. 6 and 7) at a tangent with side of basin.
This gives a swirling motion to the water, which coming in contact with a weir or
guide F falls vertically with great force into the trap and thoroughly cleanses
the same.
The swirling motion above referred to prevents the splashing of the person when
using the closet, which would occur if an ordinary basin and trap were used instead
of those mentioned.
Fig. 1 shews the proposed flushing apparatus. G is a three gallon tilting vessel.
H is the container. J is the dishstone with an iron grating as usual. K is the
drain leading to the closet basin. Instead of fixing the tilting vessel G and
container Hin position shewn, it may be fixed near the closet, or it may be fixed in
any other suitable position. In places where there is considerable fall from top of
dishstone to floor of closet, the tilting vessel and container might be dispensed with,
but in all cases we prefer its use. The inlet B will require making on either right
hand or left hand of basin to suit requirements. The seat is firmly hinged to the
ware by a dovetailed hinge let into an undercut hole in the ware and leaded in.
This closet can be conveniently used as a urinal when the seat is lifted up.
From the above description it will be seen that this is a complete self-contained
pedestal wash-down closet flushed by slop water entering basin A by pipes K above
the floor level, and that it entirely dispenses with the pipes or paus usually fixed
between the seat and basin. As indicated by Figs. 3 and 5, which are plans of
proposed yards, (W being the closet) there will generally be required three or four
steps from level of yard to floor of closet, but one advantage of this sunk floor
is thai the walls of closet will be about two and a half feet lower than usual, and
so allow of freer ventilation of the yard and surroundings.

page_text: Figs. 1 and 2 shew sections and Figs. 3 and 4 shew plans of the second part of
our invention. In order to lessen the depth of outlet drain and simplify the
construction, we preferably make the closet in two pieces of ware as shewn by
Fig. 2.
Lis the basin with inlet as before mentioned. M is a P trap prepared with a
drop as shewn; the advantage of this drop is manifest. This drop may be increased
to any desired extent. The rim N is dovetailed to fit loosely into the undercut
socket O. The said basin and trap (preferably after being burnt) are attached to
each other by special cement. The dovetail O and rim N are a preparation for
doing this firmly and expeditiously. The outlet may thus be turned to any angle
before basin and trap are attached to each other so as to suit position of drain.
The inlet to basin will require making on right-hand or left hand as previously
described in the first part of our invention. The seat may be fixed in the manner
before described, and we have then a complete self-contained wash-down pedestal
water closet, flushed by slop water entering basin L by pipes K above the
closet floor.
In the third part of our invention, we make the closet in two pieces, and connect
them (preferably after being burnt) as described in the second part of our invention,
but to reduce the cost we make top of basin and seat circular in plan. The seat is
fastened down to the basin in the ordinary approved manner. By this arrangement
the P trap can be turned in any direction to suit outlet drain, and the basin may
be turned to a suitable angle to suit inlet drain. When necessary, however, the
inlet B to basin will require making on right hand or left hand as previously
described. When the basin and trap are cemented together a complete self-
contained pedestal wash-down-closet is obtained flushed by slop water conveyed to
the closet basin above the floor level as described.
In the fourth part of our invention, we make a still simpler and cheaper arrange-
ment, but it is not a pedestal closet.
A round annular basin and an ordinary trap are made in separate pieces and
when being placed permanently in position for use the basin can be turned, so that
the inlet can point in any direction to suit drain K, and the trap can be turned, so
that the outlet may point in any direction to suit outlet drain, after this is done the
joint between basin and trap can be made in the usual approved manner.
ordinary seat with flag or wood riser is then fixed to cover the basin, trap, and inlet
and outlet pipes, and a complete wash-down slop water closet is obtained.
An
Lastly we wish it to be understood, that we are prefectly aware that the annular
basin is not new, but is particular arrangement and adaptation in combination with
a top or side flush (i.e. the admission of slop water into and at a tangent with the
closet basin above the closet floor) we believe to be entirely novel, and never
hitherto satisfactorily accomplished.
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. A complete self-contained pedestal wash-down slop water closet, with an
annular basin in combination with a top flush, arranged and acting substantially as
described in part one of our invention, and as shewn by Figs. 6. 7 and 8.
2. The combination of a top flush with self-contained pedestal wash-down slop
water closet, and an annular basin arranged and constructed in two pieces of ware,
so that they may be easily and firmly attached after being burnt, substantially as
set forth in part two of our invention, and shewn by Figs. 2 and 4.
3. The combination of a top-flush with a complete self-contained pedestal wash-
down slop water closet and an annular basin, arranged and constructed in two pieces
of ware, so that they may be easily and firmly attached after being burnt, substan-
tially as set forth in part three of our invention.
4. The combination of a top flush with a complete wash down slop water closet
and an annular basin, arranged and constructed in two pieces of ware, so that they

part 4 of our invention.
