Improvements in and relating to Water Closets.
We, JAMES DUCKETT and ALFRED DUCKETT, both of Mitre Works, Burnley, in tho
County of Lancaster, Brick and Sanitary Pipe Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements upon an invention, for which Letters Patent
were granted to the said James Duckett, bearing date the seventh day of March 1887,
and numbered 3431.
The object of one portion of our present invention is to reduce the height of the
closet trap & pan, that the same may be less costly in construction, less liable to
fracture, more portable, and also more adaptable, where the sewer drains are laid
insufficiently deep, to admit of closets of the height of those of the previous patent.
For this purpose, we place the tipper box above, instead of below, the level of the
yard flags.
The tipper box may assume a position outside the kitchen wall, as illustrated in the
drawing accompanying the specification of the previous patent; or it may be placed
inside the kitchen, below the sink stone. It will, therefore, be obvious, that the degree
of inclination from the tipper box to the main sewer, by this arrangement, will be
considerably increased, ensuring a better gravitation of waste water from the tipping
tank, to the drain or sewer. Or, if the gravitation be sufficient, a less height of closet
may be used.
We purpose dispensing with the dish-brick, and substituting therefor, a perforated
plate or slotted grid, sufficient in size, to cover the tipper box. This plate or grid is
securely fixed to the tipper box by bolts, so that the tipper may not be tampered
with by children or inexperienced persons.
The invention further consists in forming the pan of the closet, or a section thereof,
& the upper box of one piece of earthenware. We, however, prefer the pan to be
in two or more sections, which are placed one above another. The section nearest the
trap is open in front to its fullest extent, even wider than the pan itself, that the
mouth of the tipper may protrude four inches, more or less, within the interior of
the pan. The outlet from this section of the pan is circular in plan, so as to adapt
itself to the socket of an ordinary trap, which may be turned in any direction to suit
the drain.
The elevation of the tipper as above described, to the position of the first section of
the pan or that nearest the trap, has the effect of causing the water from the tilting
tank or tipper to fall with great force vertically into the trap, ensuring a thorough
displacement of any sediment which may have a tendency to lodge in the body of
the trap; whilst paper or matter floating on the surface of the water is driven by
the force of the flush to the mouth of the outlet of the trap, & through it to the main
drain.

COMPLETE SPECIFICATION.
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 Waste Water closets similar to those for which Letters

page_text: Patent were granted to the said James Duckett bearing date the 7th day of March 1887,
No. 3431.
The present invention has a two-fold object. The first object is to combine the
flushing chamber or tank with the closet pan or a section or length of such pan in
one piece of earthenware. The pan is open to its full width at its point of connection
with the flushing chamber, so that the mouth of the tipper may protrude into the
interior of the pan or to a point horizontally beyond the vertical face of the pan or
extension pipe above. The second object is to construct the outlet from the pan
(combining the flushing chamber) circular in plan to adapt it to the socket of an
ordinary trap, that the outlet from the latter may be turned in any direction to suit
the main drain.
And in order that our invention may be properly understood and readily carried
into practical effect, we have hereunto attached the accompanying sheet of drawings
marked with figures and letters of reference. Fig. 1 is a sectional elevation and
Fig. 2 a plan of a waste water closet constructed in accordance with our invention.
Figs. 3 and 4 are similar views of a waste water closet with the arrangement slightly
modified.
In Figs. 1 and 2 the tipper-box or chamber A is connected to the pan Bor a section
of the same in one piece of earthenware. The opening to the pan from the flushing
tank or chamber A is in width equal to the diameter of the pan B, so that the
mouth of the tipper C may protrude into it say four inches or thereabouts.
This arrangement of the chamber A and pan B renders the former considerably
less in size, and more compact in form with less liability for leakage than when not
permanently attached to each other, and with the mouth of the tipper not so
protruding. Another essential qualification in this arrangement is, that when the
water is discharged from the tipper it falls almost vertically with great force direct
into the trap D, ensuring a thorough displacement of sediment which may have a
tendancy to lodge therein.
It will be obvious that paper or matter floating on the surface of the water con-
tained in the trap will also necessarily be driven or swept effectually by the force of
the flush through the trap to the main drain.
To connect the pan B with the seat G, an extension pipe B' is employed, whilst
the outlet at B' is made circular in form to fit the socket of an ordinary or other
suitable trap D, so that the latter may be capable of turning in any direction to meet
the main drain; inlet junctions E and F being also provided to convey waste water
to the tipper C.
In Figs. 3 and 4, the extension pipe connecting the pan B with the seat G is
represented as being in two sections or lengths B2 and B³, the latter inclining in front
from socket to base. The pan B is similarly constructed, and connected to chamber A
as described in foregoing description with the exception that the outlet of the pan Bis
made to fit the socket of the annular basin H.
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. The combination and arrangement of chamber A and pan B, the latter fitting the
socket of an ordinary trap, substantially as described and illustrated for the purpose
set forth.
2. The combination of chamber A, pan B and protruding tipper C, substantially as
described and illustrated.
