PROVISIONAL SPECIFICATION.
Improvements in Wash-out Water Closet Basins and the Flushing
of the same.
I, RICHARD HUNT WILDING of the firm of S. B.. Wilding & Sons of 17 Lime
Street, Preston in the County of Lancaster, Plumber and Decorator do hereby..
declare the nature of this invention to be as follows :—
The water closets to which my invention more particularly relates, are of the
class known as wash out closets and pedestal closets of a like description, and
my invention has for its object, the obtaining of a greater depth of water
in the closet basin, so as to allow sufficient depth of water in the basin to
cover the soil or excreta, when the closet is in use and thus prevent the effluvia
arising from the soil being partially exposed to the air and not being covered with
water, as is the case with wash out closets of the usual kind and also for the better
flushing of the basin and trap.
In the bottom of the bowl or basin of a wash out. closet or pedestal closet of this
kind, a sinking or channel is made, commencing from the bottom of the basin where
the inlet arm or flushing fan is fixed and running in a direction towards the outlet
from the basin into the closet trap, and the bottom of the said channel is made to
gradually rise up to the aforesaid outlet.
This channel is so contracted along its course that the soil is prevented from
spreading and escaping from the force of the flush; during, the discharging of the
contents of the basin. The flush is directed with greatest force along this channel,
thus driving the contents into and through the trap and displacing the water and
soil in the basin with clear water, whilst part of the flush is also used for cleansing
the other parts of the basin.

COMPLETE SPECIFICATION.
Improvements in Wash-out Water Closet Basins and the Flushing
of the same.
I, RICHARD HUNT WILDING, of the firm of S. B. Wilding & Sons, of 17 Lime
Street, Preston, in the County of Lancaster, Plumber and Decorator, 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 water closets to which my invention more particularly relates are of the
class known as "wash-out" closets and pedestal closets of a like description, and
my invention has for its object the obtaining of a greater depth of water in the
closet basin so as to allow sufficient depth of water in the basin to cover the
soil or excreta when the closet is in use and thus prevent the effluvium arising
from the soil being partially exposed to the air through not being covered with
water as is the case with wash-out water closets of the usual kind and also for
the better flushing of the basin and trap.
In the bottom of the bowl or basin of a wash-out closet or pedestal closet of this
kind a sinking or channel is made commencing at one end at a point below the
flushing fan and running towards the outlet from the basin to the trap and the
bottom of the said channel is made to gradually slope up to the edge of the said
outlet. This channel is so contracted along its course that the soil is prevented

page_text: from spreading and escaping from or avoiding the force of the flush during the
discharging of the contents of the basin.
The flush is directed with greatest force along this channel thus driving the
contents into and through the trap and replacing the water and soil in the basin
with clear water whilst part of the flush is also used for cleansing the other parts
of the basin.
In the accompanying drawings,
Fig. 1 is a longitudinal section;
Fig. 2 a transverse section; and
Fig. 3 a plan (partly in section) of a wash out water closet basin of the pedestal
class embodying my improvements as above described.
a is the channel or depression in the lower part of the basin b. c is a form of
flushing fan I preferably employ in which the outlet is enlarged at its central
part in order that the greatest volume and force of the water in the operation of
Hushing may be directed on to the channel part of the basin so as to drive the
contents into and through the trap d whilst the water issuing from the bottom and
ends of the side wings c c serves to cleanse the sides and remaining portion of the
interior of the basin b. The broken line e at Fig. indicates the position of
the water line.
C
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
Constructing wash-out water closet basins with a depression or channel
substantially as herein described and shewn in the drawings for the purpose
specified.
