PROVISIONAL SPECIFICATION.
Improvements in Gullies.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Co. of Deptford in the
County of Kent, Engineers, and WILLIAM SPINKS of 9 Albert Square, Manchester,.
in the County of Lancaster, Civil Engineer do hereby declare the nature of this
invention to be as follows:
These improvements refer to gullies especially those known as "intercepting rain
water gullies" which are used in connection with rain water pipe outlets, and those-
used in connection with outlets from baths, lavatories and sinks or slopstones.
We provide the gulley with a dirt box for decreasing the inconvenience of silt
being carried into the drain pipe and provide in connection therewith means for
ventilation or oxydation. We also improve the form of the trap part of the gully
for facilitating cleaning and of the body of gully for readier connection with the
inlet and the outlet.
As applied to an intercepting rain water gully we prefer to arrange the dirt box
on one side and we provide a hinged or other lid to cover the dirt box and the inlet
part of the trap of the gulley. This lid is grid-shaped or perforated over the dirt
box for the purpose of ventilation. The wall between the trap and the dirt box
reaches somewhat above the level of the water in the trap. The bottom of trap
part of gully is by preference rounded inside to facilitate cleaning and the inlet is
preferably formed as an upward bend and the outlet with a downward bend so as
to admit of connection with straight rain and drain pipes respectively. The inlet.
for rain water may be made circular D shaped, square or polygonal in section to
suit the form of rain pipe to which the gully is connected.
When adapting the improvements to gullies for outlets from baths, lavatories or
sinks we provide the gully with a trough adapted for connection with the outlet
from the bath and provided with a grid-shaped or perforated cover which may be
hinged thereto and is flush with the surface of the pavement or ground. The
outlet to the drain pipe may be on one side. The trough is in some cases made of
stone-ware.

COMPLETE SPECIFICATION.
Improvements in Gullies.
We, EDWIN JAMES PRESTON of the Firm of J. Stone & Co. of Deptford in the
County of Kent, Engineers and WILLIAM SPINKS of 20 Park Row, Leeds, in the
County of York, Civil Engineer do hereby declare the nature of this invention and
n what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
The improvements refer especially those known as intercepting rain water gullies
which are used in connection with rain water pipe outlets and those used in
connection with outlets from baths, lavatories, and sinks or slopstones.
We provide the gully with a dirt box for decreasing the inconvenience of silt
being carried into the drain pipe and provide in connection therewith means for
ventilation or oxidation.
The accompanying drawing illustrates our invention as applied to an intercepting

page_text: rain water gully, Figure 1 being a longitudinal section, Figure 2 plan and
Figure 3 a cross section on line a a.
The dirt box A is arranged on one side and a hinged or other lid B is provided
to cover the dirt box and the inlet part C of the trap of the gully. This lid B is
perforated over the dirt box A for the purpose of ventilation. The wall D between
the trap and the dirt box A reaches somewhat above the level of the water in the
trap. The bottom of the trap is by preference rounded inside as shewn in Figure 1
to facilitate cleaning and the inlet is preferably formed as an upward bend E and
the outlet with a downward bend F so as to admit of connection with a straight
rain pipe at the inlet and a straight drain pipe at the outlet. The inlet for the
rain water may be made circular, D shaped, square or polygonal in section to suit
the form of rain pipe to which the gully is connected.
Figure 4 is a longitudinal section, Figure 5 a plan and Figure 6 a section on
line bb, Figure 5, of a gully suitable for the outlet pipe from a bath, lavatory or
sink without encroaching materially on the footpath and yet so constructed as to
comply with bye laws requiring a considerable space from the pipe leading from the
sink to the gully open to the air. For this purpose the gully is provided with a
long trough G which by a midfeather G₁ is divided into a channel for the water
from the sink pipe to the gully and a channel forming a dirt box both being covered
by the cover H which has an opening over the said dirt box for ventilation. This
cover H may be hinged as shewn and is flush with the surface of the pavement or
ground.
The gully proper may also have the dirt box A as in the previous example. The
outlet F to the drain may be on one side as here shewn. The trough G is in some
cases made of stoneware.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A gully provided with a dirt box such as A separated from the gully proper
by a partition D, the cover B over the same being perforated for ventilation
substantially as described and shewn.
2. A gully provided with a long trough between the sink pipe end and the gully
trap, said trough being divided by a longitudinal feather into a water channel and
a dirt box with a common perforated cover substantially as described and shewn.
