F.A
"
This invention relates to "improvements in water-closets whereby the escape of
sewer gas therefrom is prevented.
In carrying out my invention I provide the pan with an overflow arm
communicating with the flushing. rim-and-with the pan in such a manner that
each time the closet is flushed a certain quantity of the flushing water passes from
the rim into the herein before mentioned overflow arm and effectually seals the trap
from the pan or basin to the box of the closet so that foul gas cannot escape; an
outlet is also provided which prevents an overflow of the basin from the effect of
suction..
In order to enable iny invention to be better understood I will proceed to
describe the same by reference to the accompanying drawing in which figure 1 is a
section and figure 2 an elevation of a water closet pan or basin constructed according
to my invention.
::
A, is the pan or basin; B, the flushing rim of same; C, the overflow arm; D; the
inlet to the overflow arm C, from the flushing rim B; E, overflow outlet from the
pan or basin; F, ordinary overflow openings.
By this construction of water closet pan or basin it will be evident that each
time the closet is flushed- a certain quantity of the flushing water will-pass from
"the rim B; through the inlet' D into the overflow arm C, and will effectually seal
the trap from the pan' or basin to the box of the closet and thus prevent any escape
of foul gas, and the outlet E will prevent any overflow of the basin from the effect
of suction.
Having thus described my invention and the manner of performing the same
what I claim is :-
The construction and employment of water-closet pańs or basins having an inlet
such as D to the overflow arni from the flushing rim substantially in the manner
and for the purpose herein before described and represented in the accompanying
drawing.

In Witness whereof I the said Henry Conolly have hereto set my hand

eight hundred and eighty two..
