Improvements in the Construction of Gullies and Drains for Streets
and other Places.
I, JOHN PHILLIPS, of Dorney House, Disraeli Road, Putney, in the County
of Surrey, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
This Invention relates to Improvements in the trapped Catch-pit gully which I
invented, and the Metropolitan Commissioners of Sewers adopted, in 1848; and which
has been generally used in the Metropolis and elsewhere ever since. My present
Invention consists first, in making the catch-pit gully oblong or square instead of
elliptical or circular in plan, and the sides thereof pyramidal, or expanding towards
the bottom, instead of vertical in section, and in putting a frame, with a movable
grate therein, round the top of the catch-pit level with the street gutter; secondly,
in making the trapped outlet drain from the upper part of the catch-pit in a line with
the street gutter instead of at the side of the roadway; thirdly, in putting an
inspection box, with a movable stopper therein, on the head of the said drain, and a
fraime round the top of the inspection box, with a hinged cover therein, also level with
the street gutter; and fourthily, in carrying a pipe, with air-tight joints, from the
upper part of the said drain, going to the sewer from the catch-pit gully, to the top
of the adjoining houses or other buildings, for ventilating not only the said drain, but
the sewer into which the said drain is connected.
The Improvement obtained by making the catch-pit gully oblong or square in plan,
and the sides thereof pyramidal in section, is threefold: first, it gives the catch-pit
much larger capacity at the lower part, where it is required, for holding the debris
washed down from the street; secondly, it contracts the upper part of the catch-pit,
and thereby reduces evaporation from the water-surface there; and thirdly, the
enlarged space at the lower part of the catch-pit enables the debris and foul water
therein to be more easily removed therefrom by the scoop which is used for that
purpose.

page_text: The Improvement obtained by putting the Inspection box at the head of the gully
drain, with the movable stopper at the bottom, and the hinged cover at the top,
is two fold first, it affords immediate, access both to the trap and the drain
for examining or cleansing the same without breaking up the gutter or roadway to do
so; and secondly, it enables the foul water in the catch-pit to be scooped or pumped
out into the drain and the sewer at the same time the debris is being removed from
the catch-pit. When the catch-pit is thus emptied of foul water it should be at once
filled with clean water by a hose from a hydrant, stand-pipe, or water-cart.
The improvement obtained by carrying the pipe from the upper part of the gully
drain to the top of the adjoining houses or other buildings is twofold: first, the said
pipe ventilates, above the houses, the said drain, and thus prevents the foul air therein
from being forced and escaping through the water in the trap and gully, and thence
into the street; and secondly, the said pipe ventilates, also above the houses, the sewer
into which the said drain discharges, and thus prevents the foul air in the sewer from
escaping into the street.
The improved pyramidal catch-pit gully with frame round the top of same for
receiving the movable grate; the trapped outlet drain from the upper part of the
catch-pit in line with the street gutter; and the inspection box on the head of the
drain, with the frame round the top of same for receiving the hinged cover; I make
of cast iron in one piece, or, for convenience of casting, in two pieces bolted together.
The other movable parts for making the apparatus complete, namely, the movable
grating over the gully, the hinged cover on, and the movable stopper in, the inspection
Box, I also make of castiron. The ventilating pipe going from the upper part of
the gully drain to above the adjoining houses or other buildings, I make of stoneware,
castiron, or lead, with tight joints.

Improvements in the Construction of Gullies and Drains for Streets
and other Places.
I, JOHN PHILLIPS, of Dorney House, Disraeli Road, Putney, in the County of
Surrey, 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 :-
This invention relates to improvements in the trapped catch-pit gully, which I
invented, and the Metropolitan Commissioners of Sewers adopted in 1848, and which
has been generally used in the Metropolis and elsewhere ever since. My present
Invention consists, first, in making the catch-pit gully oblong or square instead of
elliptical or circular in plan, and the sides thereof pyramidal, or expanding towards
the bottom, instead of vertical in section, and in forming or attaching a socketted
frame, with a movable grate therein, round the top of the catch-pit level with
the street gutter; secondly, in making the trapped outlet drain from near the
upper part of one end of the catch-pit in a line with the street gutter, instead of at
the side thereof next the roadway; thirdly, in putting an inspection box with a
movable stopper therein on the head of the said drain, and a socketted frame round the
top of the inspection box, with a hinged cover therein also level with the street gutter';
and fourthly, in carrying a pipe with air-tight joints, from near the upper part of
the said drain leading from the catch-pit gully to the top of an adjoining house or
other building, for ventilating the said drain, and also the sewer with which the said
drain is connected.
The improvement obtained by making the catch-pit gully oblong or square in
plan, and the sides thereof pyramidal in section, is threefold: first, the catch-pit is
largely increased in capacity at the lower part where it is required for holding the
debris washed down from the street; secondly, the catch-pit is contracted round the
upper part, whereby evaporation from the water surface there is considerably reduced;
and thirdly, the enlarged space at the lower part of the catch-pit enables the debris
and foul water therein to be more quickly and easily removed therefrom by the scoop
which is used for that purpose.
The improvement obtained by putting the inspection box, with the movable stopper
therein, at the head of the gully drain, and the hinged cover at the top of the
inspection box, is twofold: first, by opening the cover and removing the stopper
immediate access is obtained both to the trap and the drain for examining or cleansing.
the same without breaking up the gutter or roadway to do so; and secondly, the foul
water in the catch-pit may be scooped or pumped therefrom and discharged down the
drain when the debris is removed from the catch-pit. When the catch-pit is thus
emptied of the foul water it should be filled with clean water by a hose from a hydrant,
stand pipe, or water cart.
The improvement obtained by carrying the pipe from near the upper part of the
gully drain to the top of an adjoining house or other building is twofold: first, the
said pipe ventilates the gully drain above the house or other building, and thus
prevents the foul air therein from escaping through the water in the trap and the
gully, and thence into the street; and secondly, the said pipe also ventilates the sewer
into which the gully drain discharges, and thus the foul air in the sewer is prevented
from escaping into the street.

page_text: The improved pyramidal catch-pit gully with socketted frame round the top of same
for receiving the movable gully grate the trapped outlet drain from near the upper
part of the catch-pit in line with the street gutter; and the inspection box on the
head of the gully drain, with the socketted frame round the top of same for receiving
the hinged cover; I make of cast-iron in one piece, or for convenience of casting in
two or more picces with flanges at the joints, all firmly bolted together so as to be
perfectly water-tight. The other movable parts for making the apparatus complete,
namely, the movable stopper in the inspection box, the hinged cover in the top of
same, and the movable or hinged grating over the catch-pit gully, I also make of
cast-iron. The ventilating pipe going from near the upper part of the gully drain
to the top of an adjoining house or other building, I make of stoneware,. cast-iron, or
lead, with air-tight joints.
I now proceed to describe, with reference to the appended explanatory sheet of
drawings, the manner in which my invention is or may be carried out in practice.
Fig. 1 is a plan, Fig. 2 a longitudinal section on the dotted line A, A, and Fig. 3
a transverse section on the dotted line B, B, of a trapped pyramidal catch-pit gully
placed under a gutter at the side of a street, Fig. 4 is also a transverse section of
one side of the street, shewing the outlet end of the pyramidal catch-pit gully under
the gutter, the gully drain going to the sewer under the centre of the street, and
the pipe, ventilating the drain and the sewer, going to the top of an adjoining house
or building.
C is the gully grating receiving rainwater from the gutter and discharging the
same into the pyamidal catch-pit gully G, in the bottom part of which the debris
washed down from the street by the rainwater settles, and thus is prevented from
passing down the drain into the sewer M. J is the water-trap, near the upper part
of one end of the gully G, preventing foul air in the drain F from passing into the
gully G, and thence through the grating Cinto the street. The water-trap J is also
the passage through which the rainwater falling into the gully G discharges into the
drain F, and thence into the sewer M, as shewn by the arrows. D is the inspection
box, K the movable stopper therein, and L the hinged cover thereon at the head of
the drain F, for readily examining or cleansing the water-trap J and the drain F,
and for pouring or discharging the foul water in the gully G down the drain F into
the sewer M. His the socketted collar round the top of the gully G for receiving
the grating C, which should loosely fit in the collar H, and may be hinged at one
end. The dotted line E, E, iu plan Fig. 1, shows the inside of the gully & near the
bottom thereof.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same may be performed, I declare that what
I claim as novel or original in the same is :-
1. The construction of a pyramidal catch-pit gully with socketted frame round the
top of same for receiving the movable or hinged gully grate.
2. The trapped outlet drain from the upper part of one end of the catch-pit gully
in line with the street gutter.
3. The inspection box on the head of the gully drain, with the movable stopper
therein, and the socketted frame round the top of same for receiving, the hinged
cover..
4.- The construction of a pipe going from near the head of the gully drain to the
top of an adjoining house or other building, for ventilating the said gully drain, and
also the sewer into which the gully drain discharges.
