Improvements in Gulleys and Traps for Streets and like Places.
I, WILLIAM BOYDELL, of Brown Street Ironworks, Leigh, in the County of
Lancaster, Ironfounder, do hereby declare the nature of this invention to be as
follows:-
--
This invention relates to improvements in gulleys and traps such as are fitted at
the sides of roads and other like places for the passage of waste water to the
sewers.
The objects of my invention are to prevent the return of foul air or sewer gas,
and to enable any accumulation in the drain or sewer to be removed without
opening the drain.
In the accompanying drawing
Fig. 1 is a sectional side view of a gulley constructed according to this
invention, and
Fig. is sectional side view of part of the same with flushing cap.
In this invention I construct a gulley as a with a water seal 6 formed on sewer
pipe c for entrance to sewer as d, by means of a groove e between the upper
portion of the sewer pipe cand the walls a¹ of the gulley a in which to place the
end and one of the side edges of a cover as c¹ that is formed to fit over the mouth
of the sewer pipe, with a space between the inside of the cover and the top and one
side of the sewer pipe: the surface level of the water contained in the gulley a will be
constantly on a line with the top of the sewer pipe, but the edges of the aforesaid
cover will be below the level of the water. By theso means dirt or refuse
entering the grid ƒ will remain at the bottom of the gulley, but fluids will pass
down the sewer pipe into the sewer, and the surface level of the water in the
gulley being above the entrance to the sewer pipe, sewer gas or foul air is
prevented returning from the sewers. If it is necessary to remove an accumulation
of dirt or sludge or otherwise to cleanse the sewer, I remove the grid f and the
cover c, and place a flushing cap you the mouth of the sewer pipe: I retain said
flushing cap in position by means of a cross bar q whose ends are placed under
lips formed on each side of the gulley: I pass a hand screw m through said bar
with the screw end resting on the aforesaid flushing cap, and by turning the screw
bind said flushing cap on to the upper end of the sewer pipe, a water tight joint
being made by means of an india rubber washer . I attach the nozzle of a hose
from the street main to the screwed inlet pipe of the flushing cap, and the
pressure of water from the main when allowed to enter the sewer rushes the
obstructions and cleanses the sewer.

I, WILLIAM BOYDELL, of Brown Street Ironworks, Leigh, in the County of Lancaster,
Ironfounder, 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 improvements in gulleys and traps such as are fitted at
the sides of roads and other like places for the passage of waste paper to the sewers.
The objects of my invention are, to prevent the return of foul air or sewer gas, and
to enable any accumulation of dirt, sludge, or foul air in the drain or sewer to be
removed without opening the drain. I effect these objects by the means hereinafter
described; reference being made to the accompanying sheet of drawings, in which
Fig. 1 is a sectional side view, and Fig. 2 a sectional transverse view of a gulley
constructed according to this invention: Fig. 3 is a sectional plan drawn through
line A A on Fig. 1: In Fig. 4 a surface plan of the gulley is shewn complete with
grid: Fig. 5 is a sectional side view of gulley with the grid removed and a flushing
cap placed over the inlet to sewer or drain. In these views similar letters refer to
similar parts. In this invention I construct a gulley as a with a water seal b formed
on the sewer pipe c by means of a groove e between the upper portion of the pipe c
and the walls a¹ of the gulley in which to place the lower edge of one side, and the
two end edges of a cover as c¹ that is formed to fit over the mouth of the sewer pipe
with a space between the inside of the cover and the top and one side of the sewer
pipe or inlet c by which waste water is conveyed to the drain: the surface level of
the water contained in the gulley a will be constantly on a line with the top of the
sewer pipe, but the edges of the aforesaid cover c¹ will be below the level of the
water.
By these means dirt or refuse entering the grid f will remain at the bottom of
the gulley, but fluids will pass down the sewer pipe into the sewer, and the surface
level of the water in the gulley being above the entrance to the sewer pipe, sewer
gas or foul air is prevented returning from the sewers. If it is necessary to remove
any accumulation of dirt or sludge or otherwise to cleanse the sewer,
remove the
grid and the cover c¹ and place a flushing cap g on the mouth of the sewer pipe;
I retain said flushing cap in position by means of a cross bar q whose ends are
placed under flanges as j formed on each side of the gulley: I pass a hand screw m
through said bar with the screw end resting on the aforesaid flushing cap, and by
turning the screw bind said flushing cap on to the upper end of the inlet pipe to
sewer, a water tight joint being made by means of an india rubber washer. I
attach the nozzle of a hose from the street main to the screwed inlet of the
flushing cap, and the pressure of the water from the main when allowed to enter the
sewer rushes the obstructions and cleanses the sewer. The herein before described
flushing cap may by the same means be employed for removing from the drain or
sewer foul air to enable workmen to enter the sewer with safety or for applying the
smoke test.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that
what I claim is :-
1st. In gulleys and traps such as are fitted at the sides of roads and other places
for the passage of waste water to the sewers, the use of a seal that is obtained by
means of a groove formed on or around the upper portion of the inlet pipe or
opening to sewer, in combination with a cover as c¹ formed to fit thereon in the
manner and for the purpose substantially as herein before described.

page_text: 2nd. In gulleys and traps such as are fitted at the sides of roads and other places
for the passage of waste water to the sewers, the use of or combination therewith
of a flushing, ventilating, or test cap as y that is formed with a screwed nozzle or
an equivalent for attaching thereto the nozzle of a hose pipe, and constructed to
fit on to the top of the inlet pipe or opening to sewer to which said flushing, veuti-
lating, or test cap is secured by a cross bar as q fitting under flanges at or near the
top of the gulley, and a binding screw as m, all for the purpose and in the manner
substantially as herein before described.
3rd. A gulley and trap for use at the sides of roads and other places having an
opening to sewers or drains constructed substantially as herein before described
either separately or in combination with a flushing, ventilating, or test cap substan-
tially as shown and described.
