PHILIP BRIGHT, of Belle Isle, Kings Cross, London, Civil Engineer, 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
Of the various kinds of water-closets in use at the present time those known as
the "wash-out and the "wash-down po sess respectively certain advantages
which have caused them to be largely employed they both, however, possess
certain disadvantages which militate somewhat against their use
The "wash out
"
closet his the advantage that it offers a comparatively large surface of water for
the soil to fall into but the out-go of the closet, into which the soil and water are
diven over a weir, is liable to become quickly fouled with soil, and as this part is
generally in such position and of such a shape that it cannot be thoroughly
cleansed by the flushing water, unpleasant odours arise from it, and for that reason
this closet has fallen into disfavour The "wash down closet on the other hand
has the advantage that its chape enables the flushing water to act with unimpaired
force on the whole of its internal surface and in the direction of the out go, but it
has the disadvantage that the surface of water for the soil to fall into inust be
comparatively small, otherwise the closet, if the dip of the trap be reasonably deep,
will not be completely cleared of soil and paper by the flush, and consequently the
soil is liable to fall on parts of the closet which stand above the water, and to make
the same unsightly
The objects of my invention are firstly to so construct a closet that it shall
possess the aforesaid advantages of both the 'wash out' and the "wash-down"
closets, without the aforesaid disadvantages of cither secondly to introduce the
flushing water in such directions that it shall thoroughly cleanse all parts and
thirdly to secure a deeper dip to the tiap than heretofore, while maintaining the
full efficiency of the flush
In the accompanying drawings Figure 1 is a vertical section taken on line 1-1
of Figure 2 of a water closet constructed in accordance with mv 1ivention, and
Figure 2 is a plin of same
It will be seen that the real part A A of the closet is shaped as a
و
"wash-out'
while the front part A' A¹ is shaped as a wash-down The result of this is that
the weu A2 of the "wash-out part is placed neater the water inlet than here-
tofore, that the portion of the out-go extending from A2 to the bottom of the
dip A of the trap is inclined and exposed to view and that the flushing water acts
powerfully upon it as well as upon the other portions of the out-go
The inclined and visible position of the portion A² to A of the out-go, also
renders it easy to see if the closet has become untrapped by svphonage or
evaporation
I prefer to introduce the flushing water into the "wash-out portion, and on to
the part A to A' of the "wash down" portion obliquely as shown by the curved
and divergent lines in Figure 1, whereby that part of the flush is concentrated and
has a very powerful scouring effect upon the said part A² to A', which prevents
the walls of the out-go from becoming foul The oblique direction is imparted to
the flushing water by forming the outlet passages in the rim D of the closet in a
correspondingly oblique direction

page_text: The concentrated and powerful action of the flushing water, together with the
shape of the closet, enables me to make the dip of the trap deeper than has hitherto
been possible in "wash-out' or "wash-down' closets and this 15 a very
important advantage in hot countries where the trapping water is liable to
evaporate quickly and to unseal the shallow dip of trap heretofore in use in such
closets in a few hours
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
First Constructing a દ wash-out' water-closet with that portion of its out-go
nearest to the water inlet inclined, substantially as described with reference to
gure 1 of the drawings, and for the purposes specified
F
Second A water-closet consisting of a "wash-out' and "wash-down' closet
combined and adapted substantially as described with reference to the accompanying
diawings, and for the purposes specified
Third In a water-closet constructed as herein before described causing the
flushing water, or a portion thereof, to enter the closet obliquely and to be
concentrated so as to have a powerful scouring action on the inclined portion of
the out-go nearest the water inlet, substantially as, and for the purpose specified
