Improvements in Street and Yard Gulleys.
I, JOSEPH WILLOUGHBY Junr. of 14 Ermington Terrace, Plymouth in the
County of Devon, Engineer and Ironfounder do hereby declare the nature of this
invention to be as follows:-
To provide a gulley wbich is more perfectly sealed than those hitherto in use so
that in case of flooding, the gulleys in low lying districts may act as "non-return
valves" and prevent the said low lying districts being flooded by the contents of
the sewers rising through the gulleys into the streets yards or other places where
they may be fixed.
I construct my gulley in any of the usual patterns or shapes, and in connection
with the discharge opening to the sewer from the gulley or sealing chamber in
connection with the gulley. I attach a valve which can be made of metal, rubber, or
any approved material; and this valve is so arranged that while providing for the
free passage of any discharge from the gulley to the sewer, it shall prevent the
return of sewage from the sewer through the gulley to the street, yard, or other
place where the gulley may be fixed.

JOSEPH WILLOUGHBY Junior 14 Ermington Terrace Plymouth, Engineer and
Marine Surveyor, 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 has for its object the provision of a more effectual seal in the
construction of gulley traps for streets, yards, gutters and other places through
which apparatus water is carried into sewers and pits.
It is well known that owing to floods and other causes, the gulleys in low lying
districts act as outlets from the sewers or pits through which in the case of floods
or overflow the sewage or contents of the sewer or pit finds its way back into the
street or yard and a nuisance is created.
In times of drought the level of the water in the soil pit of the gulley or in the
sealing chamber is lowered by evaporation and then the sealing is destroyed and
the gases from the sewer passing through the sealing chamber & gulley to the
street becomes a source of danger to passers by & residents near.
Now by my invention the reflux of sewage or liquid matter from the sewers to
the streets is prevented, and the evaporation of water in the sealing chamber and
consequent unsealing of the gulley is effectually stopped.

page_text: By referring to the accompanying drawing it will be seen that the valve A is
hung in such a position that any matter can enter direct to sealing chamber B
from the soil pit C, whereas any reflux from the sewer closes the valve A thus
preventing the passage of the reflux matter into the soil pit C and from thence to
the street.
The valve A is hung on lugs in any suitable manner and rests on a seating and
can be easily reached and unhung by the hand.
The valve A may be constructed of any suitable material or may be of any
suitable shape & arranged in any required manner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
The use in a gulley of a valve situated between the soil pit and the sealing
chamber as herein before described or any mere modification thereof.
Dated this 19th November 1896.
