PROVISIONAL SPECIFICATION.
Improved Wash-out Water Closet Apparatus.
We, ALBERT SWEETNAM and JOHN WINKWORTH both of 26 Livingstone
Road, West Brighton, Sussex, do hereby declare the nature of this invention
to be as follows:-
The object of our invention is to make a wash-out closet that shall contain a fair
depth of water and be so constructed as to allow an after flush of water to provide
a sufficient seal to the first trap.
Our improved closet apparatus of the pedestal character and provided with two
traps, each arranged to contain a seal of water. A flushing rim is used for
preference and near the supply to this flushing rim is provided a small chamber
at the back of apparatus and homogeneous therewith to which the flushing water
has access and the outlet to this chamber is small and slightly below the water line
of the seal of the first trap. The second trap is ventilated to prevent syphonage.
An examination cap is fitted at top in front of apparatus to allow of access to the
second trap.
We propose to make our improved apparatus as far as possible all in one piece,
and it will have very much the appearance and advantage of a valve closet without
the complicated machinery attached to a valve closet.

COMPLETE SPECIFICATION.
Improved Wash-out Water Closet Apparatus.
We, ALBERT SWEETNAM and JOHN WINKWORTH both of 26 Livingstone
Road West Brighton, Sussex Gentlemen, 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 object of our invention is to construct a wash-out closet that shall contain a
fair depth of water and shall also allow an after-flush of water to provide a sufficient
seal to the first trap.
Our improved closet apparatus is of the pedestal character, and provided with
two traps each arranged to contain a seal of water. A flushing rim is used for
preference, and near the supply to this flushing rim is provided a small chamber at
the back of the apparatus and homogeneous therewith to which the flushing water
has access, the outlet to this chamber is small and slightly below the standing water
level in the basin.
In order that our invention may be more readily understood we append the
accompanying sheet of drawings in which Figure 1 represents a vertical section
through our improved apparatus, and Figure 2 being a general plan of the same.
The like letters of reference indicate the like parts throughout.
A is the basin of the apparatus and is furnished preferably with a flushing rim in
any ordinary way, and in order that the water standing in the basin A may form an
air-tight seal to the rest of the apparatus, a partition or lip B is formed extending
from the top of the basin to slightly below the water line as shown.
Crepresents the chamber formed at the rear of the basin to contain the after
flush water, and is connected with the inlet supply pipe D. This chamber C is

page_text: constructed of suitable size to contain about sufficient water to fill the seal in the
basin.
E is the lower trap or seal communicating with the soil pipe in the usual way.
The head of the soil pipe is ventilated by means of the ventilating pipe nozzle F,
and the space between the upper and the lower traps is also ventilated by means of
a grated outlet G, placed in the side of the same, and from which a pipe or enclosed
chamber passes around the trap (but within the wall of the pedestal) and ultimately
communicates with the ventilating pipe F; the object of the ventilating contrivance
being principally to prevent syphonage taking place and the water being drawn
away from the traps.
An inspection hole fitted with a suitably seated cap H is provided at the front
of the apparatus to give access to the space between the two traps and also the
lower trap.
When our improved apparatus is in action the water rushes with considerable
force through the supply pipe D and around the rim thoroughly cleaning out the
basin A. and at the same time filling the after-flush chamber C through the
opening K. On the flush water being expended the water in the flush chamber C
slowly runs down into the basin through the small outlet provided for it at P, and
fills the basin up to the necessary height to form the seal, thus making the passage
of sewer gas and the like from the soil pipe to the basin practically impossible, and
a greater amount of water is reserved in the bottom of the basin F than is ordinarily
obtained in flush-out closets.
We form the whole of our improved apparatus in one piece of earthenware with
the exception of the removable parts.
The double dotted lines shew how it may be formed for connection with the
drains in cases where the soil pipe has to be taken out at the back through a wall,
or under other similar conditions.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. An improved flush out water closet basin, substantially as herein before
described in this Specification, and illustrated by the accompanying drawings.
2. In an improved flush out water closet apparatus, the chamber C in conjunction
with the basin A, the said chamber Chaving an inlet D and an outlet P and being
capable of holding sufficient water to form a seal in basin A, when said water has
escaped from chamber C all as before described in this Specification and illustrated
in the accompanying drawings.
3. In an improved flush out closet apparatus, the combination of the chamber C
and basin A in conjunction with the trap E, ventilated as shown by perforations G
in the accompanying drawings.
4. In an improved flush out closet apparatus the examination cap H in conjunction
with the basin A, after flush chamber C and trap E.
