PROVISIONAL SPECIFICATION.
Improvements in Street Gullies.
I WILLIAM SYKES of 18 New Bridge Street Blackfriars, in the County of
London, Civil Engineer do hereby declare the nature of this invention to be as
follows
:-
My invention relates to improvements in gullies intended to be used for taking
away the surface water from streets and other like purposes. Gullies constructed
at present and known as stoneware street gullies possess two great faults, viz. :-
their discharge outlet comprises what is known as a swans neck which secures only
a small water seal which is likely to be unsealed by evaporation during hot weather,
and further as such swans neck is attached to the gulley very near the top, the pipes
connecting it with the sewer owing to their close proximity to the surface of the
road are likely to be broken during the process of rolling the road with a steam
roller or other superincumbent weight thus allowing sewer gas to escape through
the street gratings.
Now my invention has for its object the remedying of these two defects, by
placing the rising outlet for the water two thirds or thereabouts down the gulley
from the top, the water flows up the rising outlet pipe and discharges (over a
A shaped crest or diaphragm near the top) down the discharge outlet which gives
a great depth of water seal. The water at a point about two thirds from the top
of the gulley is void of road detritus which has been deposited, also of all leaves
and other floatable matter which rise to the surface therefore neither can escape
into the pipes to choke same. The gulley for the convenience of fitting the square
grating is made preferably square and attached thereto are the outlet apertures
formed similarly square side by side. The discharge outlet is carried down by the
side of the rising outlet to a point near the bottom of the gulley which allows the
connection to the sewer to be made well below the surface of the road where heavy
traffic cannot affect it.
I also make provision for cleansing the respective outlet shafts by means of a
bottle necked inspection hole taken from the top of the respective outlet pipes,
and terminating with a socket in which is placed a stopper preferably one of my
Patent screw stoppers described in my Complete Specification No. 7498 dated
12th April 1893. for convenience of access to this stopper I prefer the iron
gratings to be made with a circular opening attached to the flange of same.

I, WILLIAM SYKES, of 18 New Bridge Street, Blackfriars, in the County of
London, Civil 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 :-
My invention consists in improvements in gullies intended to be used for taking

page_text: The purposes. Crimes such as
"
are at present constructed and known as stoneware street-gullies possess two great
faults, viz. their discharge outlet, which comprises what is known as a "swan's
neck," ensures only a small water-seal that is liable to be destroyed by evaporation
during hot weather, and further, as such "swan's neck is attached to the gully
very near the top of the gully, the pipe connecting it with the sewer, owing to its
close proximity to the surface of the road, is liable to be broken during the process
of rolling the road with a steam-roller, or by the action of some other super-
incumbent weight, and consequently to allow sewer-gas to escape into the street.
Now my invention has reference to an improved construction and arrangement
of street gully designed inter alia to obviate the disadvantages above referred to,
as I will now proceed to explain by reference to the accompanying illustrative
drawing wherein,
Fig. 1 is a perspective view of a street gully constructed according to this
invention;
Figs. 2, 3, and 4 show respectively in vertical section (taken along the line x x of
Fig. 3), in side elevation, and in plan, the gully and its grating in their normal
positions in the ground; and
Fig. 5 shows a horizontal section of the gully taken along the line
Fig. 3.
Y y of
The outlet 1 of my improved gully is placed about two thirds of the height of
the gully from the top thereof and is connected with an upwardly extending
outlet pipe or passage 2 and downwardly extending pipe or passage 3 so that
water flowing into the gully will rise in the pipe or passage 2 and passes thence
into the discharge pipe or passage 3 over the upper edge of a vertical diaphragm 4
arranged between the two pipes or passages, the said upper edge being located
near the top of the gully. By this means a considerable depth is obtained for the
water-seal, which extends from the level of the top of the diaphragm 4 to the top
edge 1 of the outlet 1. The water at the level of the outlet 1 will be free from
road-detritus, which has become deposited in the bottom of the gully, and also from
leaves and other floatable matter, which rise to the surface of the water in the
gully,
therefore neither the detritus nor the floatable matter can escape into the
pipes 2 and 3 and choke the same. For the convenience of fitting the square or
rectangular grating 5, the gully is preferably made square in cross section. The
outlet pipes or passages 2 and 3 are suitably attached to the gully; they are
preferably, as shown, made in one therewith and of square or rectangular cross
section. The downwardly discharge-outlet passage 3 is carried down by the side
of the upwardly extending passage 2 to a point near the bottom of the gully, so
that the point of connection to the sewer, or to a connecting pipe in connection
with the sewer, may be well below the surface of the road so that heavy traffic will
not be liable to affect it. 12 desired, the connecting-pipe may be provided with a
trap 6 arranged between the water-seal and the sewer, as indicated in dotted lines
in Fig. 2, so as to permit of the gully being emptied and cleaned without liability
of sewer gas escaping through it into the atmosphere above.
Provision may be made for cleansing the respective outlet pipes or passages 2
and 3 by providing a bottle-necked inspection-hole 7, which leads from the top of
these outlet pipes or passages and terminates in a socket in which is placed a
stopper 8-preferably of the kind described in the Specification of Letters Patent
granted to me, No. 7498 of 1893. For convenience of access to the stopper 8,
I prefer the iron grating 5 to be made with a slot or opening 9 in its lateral
flange 10; a loose removable cover 11 of suitable material, for example iron, may
be placed above the slot or opening 9 to protect the stopper 8 from injury.
As will be obvious the dimensions and the form in cross section of the gully
and its outlet passages 2 and 3 can be variously modified to suit different
requirements.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The construction of a street gully with an outlet 1 and discharge pipes or
passages 2 and 3 arranged substantially as hereinbefore described with reference
to the drawings annexed for the purposes specified.
2. The hereinabove described improved construction of street gully whence the
outlet 1 and discharge passages 2 & 3 are arranged as set forth and the said
discharge passages are provided with an inspection hole terminating in a normally
closed socket, substantially as described with reference to and shown in the
drawings annexed.
