page_text: I, JOHN SHAW, 28, Rosehill Terrace, Willington-on-Tyne, Northumberland,
Ironfounder, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in gully traps, made of cast iron,
earthenware, or other material.
It consists of outer shell, internal cover, for mouth of drain, internal recep-
tical and grate for same.
The object of my invention is to prevent obnoxious gasses escaping from drains.
Also prevent the choking up of drains, which is expensive, and deteramentle to
health.
The said outer shell is provided with a raised outlet at bottom forming the
mouth of drain, and a seat for grate at top.
The internal cover is provided with legs to stand on bottom of said shell, with
space between the raised outlet and the top of cover to allow the water to flow over
into the mouth of drain, which forms a water 'seal.
The internal receptical rests on top of said cover.
The grate is provided with
a ring and projections which dip below the top of said receptical forming another
scal.
When gully is fixed in position the water flows through the openings in said
grate into the receptical, the heavy matter goes to the bottom and the light floats
on top, and is prevented from flowing over the top of receptical by means of the
projections on grate ring. When receptical is removed for cleansing there is
still a perfect seal on top of drain which will prevent the gasses escaping.
When flushing or testing of drain is required it is not nessesary to dig up any
ground or spoil any costly flooring, as the mouth of drain can be got to by
removing the said cover.
Those gully traps has two seals one a continious, and not so deep as those
now in general use as the overflow is at top of receptical.

Improvements in Gully Traps for Private and Public Buildings,
Streets, and the like.
I, JOHN SHAW, 28, Rosehill Terrace, Willington-on-Tyne, Northumberland,
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 ;-
My invention relates to improvements in gully traps, made of earthenware,
cast iron, or other suitable material.
It consists of outer shell, internal cover for mouth of drain, internal
tical, and grate, for same.
recep-
The object of my invention is to prevent the obnoxious gases escaping from
drain, when the said receptical is removed for cleansing. Also to prevent the
choking of drains, the clearing of which is expensive, and detrimental to health.
The said outer shell is provided with a raised outlet at bottom, forming the
mouth of drain, and a seat at top for said grate.
The said internal cover is provided with legs to stand on bottom of said shell,
with space between the raised outlet and the top of cover, to allow the water
to flow over into the mouth of drain, which forms a water seal.
The said internal receptical rests on top of said cover.
The said grate is provided with a ring and projections, which dip below the
top of receptical, forming another seal.
When gully is fixed in position the water flows through the openings in said:
grate into the receptical, the heavy matter goes to the bottom, and the light floats
on top, and is prevented from flowing over the top of receptical by means of the
projections on grate ring. When the receptical is removed for cleansing, there is
still a perfect seal on top of drain, which will prevent the gases escaping.
DESCRIPTION OF DRAWINGS.
On the acompanying drawings my invention is shown as it is to be carried
out in practical application.
Fig. 1 is a top view of a round gully.
Fig. 2 is a vertical section of Fig. 1.
Fig. 3 is a top view of drain mouth cover.

Fig. 4 is a side view section of street gullies.
Fig. 5 is a end view section of Fig. 4.
The same letters refer to corresponding parts on all the figures. Referring to
Figs. 1 2 3 4 and 5, A is the outer shell, B is the internal receptical, C is the
internal cover over the mouth of drain F, D is the grating with hopper or ring E 3
attached to it.
When gully is fixed in position the internal cover C which forms a water seal,
is set over the mouth of the drain F, the internal receptical B is set on top of
the internal cover C, the grate D is set into a seat in the outer shell A, with the
hopper or ring E attached, which dips into the receptical B and forms another 40
water seal at top of receptical B.
Therefore you have a double trapped gully.
When the receptical B is removed for cleansing there is still a perfect water
seal at the mouth of drain F. By this means it is not necessary to fill the gully,
with water to prevent the gases arising.
When flushing or testing of drain is required, it is not necessary to dig up
any ground or spoil any costly flooring, as the mouth of the drain can be got
at by removing the cover C.

page_text: Those gully traps have two seals one a continuous seal, and are not so deep
as those now in use, as the overflow is at the top of receptical B.
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:-
1st. A movable cover over the mouth of drain, with three or more legs to
stand on,
or other supports.
2nd. A receptical with overflow at the top, and resting on said cover over the
mouth of drain.
3rd. A double trapped gully constructed substantially as described with refer-
ence to drawings and operating as and for the purpose specified.
