Engineer, and WILLIAM JOHN HOOKING of the same place, Beamer, do hereby declare
the nature of this invention to be as follows:-
This invention relates more particularly to the construction of Water Closets using
waste water. The trap or pan of the Closet is preferably made of carthenware, which
may be glazed or enamelled on its inner surface, and has formed near the top a semi-
circular groove or ledging in communication with the inlet pipe, in such a manner,
that the wasto water, flowing through the inlet, will take or follow the curvature of
the semicircular groove or ledging, over which it discharges itself in a sheet or stream
into the trap or pan, at the back, effectually flushing the closet whilst the inner
surface at the back of the trap or pan being constantly washed by the discharge of

flush more effective, the waste water may be received in a reservoir until a sufficient
quantity be obtained when it may be automatically or otherwise discharged into the
closet. In cases where the yard trap or other source from whence' waste water is
obtained, is too low to allow for the gravitation of the water to the reservoir
or into the pan or trap of the closet, a continuation pipe is provided which may
be placed above, to make up the gap from the pan to the seat when the former is
lowered.

Improvements in and relating to Water Closets.
We, RICHARD HOOKING of 142, Colne Road, Burnley, in the County of Lancaster,
Engineer, and WILLIAM JOHN HOCKING of the same place, Beamer, 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 relates to the construction of Water Closets using waste or slop
water, and consists essentially of a groove or ledging suitably disposed in the pan
or trap of the closet, to cause the water to follow the curvature of the pan and
discharge itself in a sheet or stream over the surface of such pan, and clear the
same of excreta or foul matter which has a tendancy to adhere thereto.
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, the same letters referring to the same or
corresponding parts in the various figures.
Fig. 1 is a vertical section, and Fig. 2 a plan of a privy or closet, constructed in
accordance with our invention, in which views A represents the kitchen sink, from
which waste water is conveyed down pipe B through the dish brick, into the yard
trap C. This trap is connected by sanitary pipes C to the upper portion or rim of the
earthenware cone or pan D, in the manner seen in Fig. 2; so that the waste water
flowing from the inlet D, will take or follow the curvature of the semicircular groove
or ledging E, over which it discharges itself in a sheet or stream, effectually clearing
the surface of the cone or pan of excreta which otherwise has a tendancy to adhere
thereto. In cases where there is an insufficiency of fall to ensure gravation of the
waste water to the cone or pan, the latter together with the trap F may be sunk to
the depth required into the earth's surface an extension pipe G being used as a
connection between the cone and the seal H.
Fig. 3 is an elevation in section, and Fig. 4 a plan representing the closet, as being
in juxtaposition with the kitchen wall, in which case, the sanitary pipes C¹, represented
in Fig. 1 is dispensed with, the pipe B from sink A being connected direct to the
inlet D', as seen in Fig. 4.
It will be obvious that as the flush in both arrangements is automatically effected, it
is in no way dependent on the care or cleanliness of the person using the closet; but
is flushed by waste-water from the sink or other source at repeated intervals,
effectually flushing, from time to time, the trap F of its contents, through the outlet J,
to the main drain.
We are perfectly aware that in ordinary water closets, the water is made to take
a semicircular course, around the sides of the cone or pan, through a pipe having
a number of orifices, through which the water percolates; but this arrangement is
altogether inapplicable when using waste water, as such orifices would be constantly

page_text: made up; whereas in our arrangement, such a case is impossible, as the groove or
ledging is perfectly open, and therefore no sediment can possibly accumulate, to
cause obstruction.
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 groove or ledging E, substantially as described, for the purpose set forth.
2. The general arrangement and combination of the parts constituting a water closet
substantially as described and illustrated.
