PROVISIONAL SPECIFICATION.
Improvements relating to Gully Traps.
I, JAMES RICHARDS, of 46, Plymouth Road, Penarth, Cardiff, retired Builder,
do hereby declare the nature of this invention to be as follows:-
This invention relates to gully traps. According to this invention the cover of
the trap consists of two parts, one of which is intended to be permanently fixed in
place; the other part being movable.
The fall pipe by which water from a roof or bath or other source is delivered to
the trap extends down through an aperture provided for it in the fixed part of
the gully trap cover. When more than one pipe discharges into the gully trap
each is extended through a separate aperture. By thus carrying the pipe or pipes
into the trap the water delivered by such pipe or pipes is discharged below the
gully trap cover and not on to the upper surface thereof.
The movable part of the cover is perforated to permit surface water to pass
into the trap. The cover is preferably concave on the upper face so as to drain
towards the middle of the perforated movable part.
In gully traps arranged in accordance with this invention, the water delivered
by the pipe or pipes cannot be discharged on the upper face of the cover and so
cause flooding from clogged perforations or other cause.
The flow of the water from the pipe or pipes assists to prevent lodgement of
leaves and other refuse.

Improvements relating to Gully Traps.
I, JAMES RICHARDS, of 46, Plymouth Road, Penarth, Cardiff, retired Builder,
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 gully traps. According to this invention the cover of
the trap consists of two parts, one of which is intended to be permanently fixed
in place; the other part being movable. The fall pipe by which water from a
roof or bath or other source is delivered to the trap extends down through an
aperture provided for it in the fixed part of the gully trap cover.
When more
than one pipe discharges into the gully trap each is extended through a separate
aperture. By thus carrying the pipe or pipes into the trap, the water delivered
by such pipe or pipes is discharged below the gully trap cover and not on to the
upper surface thereof.
The movable part of the cover is perforated or grated to permit surface water
to pass into the trap. The cover is preferably concave on the upper face so as to

page_text: drain towards the middle of the movable part. In gully traps arranged in
accordance with this invention, the water delivered by the pipe or pipes cannot
be discharged on the upper face of the cover and so cause flooding from clogged
perforations or other cause.
The flow of water from the pipe or pipes assists to prevent lodgement of
leaves and other refuse.
Referring to the accompanying drawings, Fig. 1 represents in vertical section,
and Fig. 2 in plan, a gully trap made in accordance with one arrangement
comprised in this invention.
The cover of the trap consists of a movable grating a and a fixed part a
which latter may be conveniently made in one with the body of the trap. In the
fixed part a¹ is an aperture through which the fall pipe 6 is passed. This fall
pipe b, which receives the water from a roof gutter or from a bath or other source,
is extended down to a suitable length below the cover of the trap. Consequently,
the water it conveys is not, as hitherto, discharged on to the upper face of the
gully trap cover, but is carried by the pipe into the trap and discharged below the
cover. Further, the flow of water delivered by the pipe b assists by its "wash
out effect to prevent lodgement in the trap of leaves and other refuse. The trap
is, therefore, in this sense, "self-scouring." The use of bends in rain water pipes
is largely obviated as the pipes are under this invention extended down straight
into the trap.
ני
"
Surface water passes into the trap through the grating a.
When more than one pipe discharges into a gully trap made according to this
invention, separate apertures for each are provided in the fixed part a¹ of the
cover, and each pipe is extended into the trap as hereinabove described with
reference to the pipe 6 shown at Figs. 1 and 2 of the accompanying drawings.
At Fig. 3 of the drawings is shown in vertical section, and at Fig. 4 in plan, a
gully trap made on the same principle as that shown at Figs. 1 and 2. The
difference consists in dividing the grating into two parts c and c' of which the
part c is hinged by wires d, or other means, to the part e which latter is secured
by wires d to the sides of the trap. The aperture e for the fall pipe is provided
in the fixed part 2 of the cover, which fixed part is conveniently made in one piece
with the gully trap. The aperture e is shown as rectangular to take a rectangular
fall pipe, but it would be otherwise shaped to take a differently shaped fall pipe.
The part c of the grating can be raised on the hinges d to give access to the
interior of the gully trap without necessitating removal, and the whole grating c
and c cannot be removed from the trap without detaching it from the fastenings d¹
which secure it to the body of the trap.
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 :-
1. A gully trap having the cover consisting of a movable grated part and a
fixed part provided with an aperture or apertures for extending into the trap a fall
pipe or pipes receiving water from roof gutters, or a bath or other source,
substantially as hereinabove described with reference to the accompanying
drawings.
2. In relation to a gully trap, the method of delivering waste water from a fall
pipe, or from more than one, into the trap below the cover thereof, that is to say,
by extending such pipe or pipes through a suitable aperture or through suitable
apertures provided in the cover, substantially as hereinabove described.
