Gullies, and the like.
I EDGAR ALDOUS of 2 Elmhurst, Upton, in the county of Essex, Sanitary
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction and application to water closets, the
discharge pipes of baths, sinks, gullies, and the like of an improved retainer and
trap for the purpose of more effectually preventing the escape of sewer gas than
hitherto..
The improved retainer consists of a chamber of suitable shape (preferably
hemispherical) into which dips the pan of the water closet or the discharge pipe of
the bath, sink, or otherwise, the said retainer containing water so as to seal the dip
of the said water closet pan or discharge pipe. In communication with and
connected with the said retainer is or are a trap or traps thereby effecting a
separate and distinct trap to that formed by the retainer. The water in the
'retainer and in the trap, although on the same level, is kept separate so that if the
trap should become unsyphoned the retainer remains trapped.
In the case of sink-traps, gullies or the like I so connect the retainer and the
discharge pipe that the two can be removed together for cleaning out purposes or
.otherwise.

Gullies, and the like.
I EDGAR ALDOUS of 2 Elmhurst, Upton, in the county of Essex, Sanitary
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 :-
This invention relates to the construction and application to water closets, the
discharge pipes of baths, sinks, gullies, and the like of an improved retainer and
trap for the purpose of more effectually preventing the escape of sewer gas than
hitherto.
The improved retainer consists of a chamber of suitable shape (preferably
hemispherical) into which dips the pan of the water closet or the discharge pipe of
the bath, sink, or otherwise, the said retainer containing water so as to seal the
dip of the said water closet pan or discharge pipe. In communication with and
connected with the said retainer is or are a trap or traps thereby effecting a
separate and distinct trap to that formed by the retainer.
In the case of sink-traps, gullies or the like I so connect the retainer and the
discharge pipe that the two can be removed together for cleaning. out purposes or
otherwise.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1, represents
an elevation and figure 2 a section shewing my improved retainer and trap applied
'to a water closet; figure 3 is a section shewing the invention applied to a gully;
figure 4 is a plan of figure 3 with the grating removed. Similar letters in all the
figures represent similar parts.
Referring to figures 1 and 2 a, is the retainer and b, is the pan of the water
closet which is formed with a downward extension c, dipping below the level of
the water in the retainer a, as shewn in figure 2 so as to seal the dip of the pan b';
d, is the trap in communication and connected with the retainer a, and forming a
separate and distinct trap from that formed by the retainer; the water in the
retainer a, and in the trap d, although on the same level is by this construction
kept separate so that if the trap d, should become unsyphoned the retainer will
remain trapped; e, is an opening in the trap d, for ventilating and preventing the
same from becoming unsyphoned.
'1
Figures 3 and 4 shew the application of my invention to a gully the construction
being similar to that hereinbefore described for water closets; c, is the pipe which
dips into the retainer a; f. f. f, are inlets from the drains to the retainer a, the
said inlets being situated below the level of the water; g, is the grating of the
gully.
The application of my improved retainer and trap for the purpose of trapping
sinks, the discharge pipes of baths and the like will be readily understood without
further description.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. The combination of a retainer such as a into which dips an extension of the
pan of the water closet, or a pipe in the gully or the like, with a trap or traps such
as d, substantially as and for the purpose herein before described and illustrated in
the accompanying drawing.
2. The use with waterclosets, baths, sinks, gullies and the like of my improved
combined retainers and traps as hereinbefore described and represented in the
accompanying drawing.
