MENTS IN GULLY-TANK, TRAP, AND DRAIN FOR STREETS, ROADS, YARDS, MEWS', AND OTHER PLACES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, JOHN PHILLIPS, of 25, Disraeli Road, Putney, in the County of Surrey,
Sanitary Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN GULLY-TANK, TRAP, AND DRAIN FOR STREETS, ROADS, YARDS, MEWS',
AND OTHER PLACES, to be as follows:-
One part of my Invention consists of a rectangular vertical pipe, and a
rectangular horizontal pipe, both of cast iron, communicating with each other and
passing through the lower part of one end of the cast iron frame of a Gully-Grate.
By the vertical pipe, which descends into the water contained in the Gully-tank and
acts as a trap therein, the water which discharges through the Gully-grate into the '
Gully-tank rises up the vertical pipe and overflows by the horizontal pipe into the
head of a drain, which is placed immediately outside the same end of the Gully-
tank; and from thence goes by a vertical curve or steep incline direct into the
Sewer.
Another part of my Invention consists of a rectangular box of cast iron
connected with the same end of the Gully-grate-frame, and with the top of the
horizontal pipe discharging into the head of the drain. This box has a locked and
hinged cover of cast iron flush with the top of the Gully-grate and its frame, and
an opening in the bottom thereof with a movable air-tight cover therein, which
cover, by unlocking and raising the hinged cover at top, is easily removed by hand;
and thus the drain, from its head to its outlet into the Sewer, may be examined,
flushed with water by a hose or otherwise, and any obstruction therein removed,
without disturbing the paving, and digging into and breaking down to the drain.
My Improved Gully-tank is made of thick fire-clay, well burnt and glazed;
oblong instead of round, and of larger capacity than such articles are ordinarily.
made. It has also a strong internal projection with rabbet nearly all round the
top, which well supports, and keeps in place, the cast iron Gully grate and frame;
and it has no pipe, trapped or otherwise, going out of either side or end, as such
articles usually have.
Dated this 28th day of February 1884.

JOHN PHILLIPS, of 25 Disraeli Road, Putney, in the County of Surrey,
Sanitary Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN GULLY-TANK, TRAP, AND DRAIN FOR STREETS, ROADS, YARDS, MEWS,
AND OTHER PLACES, 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 the combination of a rectangular gully-tank; gully-
grate-frame with hinged grate therein at top standing over the gully-tank; vertical
rectangular pipe and trap going out of one end of the gully-grate-frame and
descending into the gully-tank against the end thereof; horizontal rectangular
overflow pipe connected with the side of the vertical pipe and trap at top and
discharging vertically into the head of a drain leading direct to the sewer; and an
inspection box over the top of the horizontal overflow pipe with hinged cover at
top and moveable, air-tight cover at bottom thereof over the head of the drain; for
receiving and discharging surface water from streets, roads, yards, mews, and other.
places; trapping the pipe in the gully-tank and so preventing effluvium in the
sewer escaping by the drain through the gully-grate into the street ; and inspecting
and cleansing the drain and removing any accumulation or stoppage therein
without digging to and opening the saine; as shewn and illustrated by the
accompanying drawings Figures 1, 2, 3, 4, 5, and 6. Figure 1 represents by plan
the hinged gully-grate a in the frame b, and the hinged cover c in the inspection
box d, fixed in the channel or gutter alongside a footway; Figures 2 and 3
represent longitudinal and transverse vertical sections of the several parts of the
apparatus, vizt the hinged gully-grate a in the frame b, the hinged cover c in the
inspection box d, the vertical rectangular pipe and trap e descending into the gully
tank f, the horizontal rectangular overflow pipe g discharging into the head of the
drain h, and the moveable air-tight cover i in the bottom of the inspection box d
over the head of the drain h. Figure 4 represents a longitudinal vertical section of
the drain leading from the horizontal overflow pipe g direct into the sewer.
Figure 5 represents a plan of the outlet end of the gully tank f, and of the head
of the drain h immediately outside it. Figure 6 is a vertical transverse section of
the top part of the outlet end of the gully tank f. In the middle of the end at
the top is a long notch k the bottom of which is level with the head of the drain h.
The notch, which is also shewn in plan at k in Figure 5, is made to receive the
horizontal rectangular overflow pipe g which has a round outlet and nozzle at the
bottom fitting into the socket m of the pipe at the head of the drain h.
The gully tank ƒ may be made of stoneware, cast-iron, or Portland cement
concrete rendered inside water-tight; but I make it by preference. of fire-clay, and
I bed it upon, and fill in or case it all round at the sides against the ground with
Portland cement concrete. The gully grate frame b, inspection box d, vertical
rectangular pipe and trap e, and horizontal rectangular overflow pipe gare all
made of cast-iron in one piece. This is bedded on thick tarred felt, or Portland
cement, laid all round the top of the gully tank and in the notch and socket m.
The hinged gully grate a, hinged cover c, and moveable air-tight cover i, are made
of cast iron in separate pieces.
By raising the hinged gully grate a, the detritus in the gully tank f may be
casily taken out with a properly formed scoop; and by raising the hinged cover c,
and removing the air-tight cover i, the drain h beneath may be readily examined,
flushed with water, and any obstruction therein removed without disturbing the
paving or the drain. The foul water in the gully tank f may also be taken out

page_text: with the scoop and poured down the drain h through the aperture occupied by the
hinged cover c. At the same time the gully tank should be filled and the drain
flushed with clean water by a hose from the nearest hydrant, or a water cart.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is, constructing gullies, and drains therefrom, for streets, roads, yards, mews,
and other places, in the mode, and with the parts separate and combined, as herein,
set forth, and shewn by the drawings.
