COMPLETE SPECIFICATION.
An Improvement in Water Closets.
I, WILLIAM BAILEY MOORE, of Cauldon House, Shelton, Stoke-on-Trent, in
the County of Stafford, China and Earthenware Manufacturer, 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 :-
My invention relates to the construction of a water closet pan and of the
channels leading to and from it in such a manner that the flush of water admitted,
effectually cleans and scours the pan, as I shall describe referring to the accom-
panying drawing which is a section of a pan and its channels according to my
invention. The water inlet channel A has a main branch B directed downwards
along the side of the pan to a contracted outlet C opening into the pan at its
bottom. It has another branch D leading into an annular channel E which extends
around the circumference of the pan at its upper edge, and which has through its
lower side a number of holes F, close to the internal surface of the pan below.
The outlet G from the pan after an abrupt bend at H descends by a passage K L
to a drain. The arrows indicate the flow of the liquid when the pan is flushed.
The main part of the water from the cistern passes down by B to the bottom of
the bowl where it is expelled with great force from the contracted orifice C into
the siphon trap of the bowl.
As the water passes from G, the short leg of the siphon, into the passage K
which forms part of the long leg of the siphon, it displaces all or most of the air in
the latter, so that active syphon action takes place, and the contents of the bowl
are forcibly ejected. In order that this siphon action may take place, the arrange-
ment and dimensions of the passages have to be substantially as shewn, so as to
cause the air to pass away with the water forced into G by the jet. The water
which passes by E and F to the rim of the bowl cleanses the latter and assists in
driving paper and soil toward the outlet G. When the water comes more slowly
from the cistern, the siphon action ceases and the bowl is charged with clean water
from the cistern. Heretofore all closets capable of holding a large body of
water in the bowl, a very desirable feature, have had a valve at the side or bottom
which was liable to become deranged, to allow the water to escape. According to
my invention, as above described, there is a large body of water in the bowl, and
there are no mechanical or moving parts liable to derangement.
The form and proportions of the pan and its channels may obviously be varied
without departing from the nature of my invention, so long as there is provision
for a rush of flushing water as at C, and for a shower of washing water along the
surface of the pan or by the outlets F.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
In combination with the pan of a water closet, an annular channel around the
upper lip of the pan with outlets to discharge streams of water along the internal
surface of the pan, and a channel descending to the bottom of the pan with a con-
tracted opening directing a current of water towards an outlet from the pan
sloping up to a siphon bend and thence leading to a drain, substantially as described.
