PROVISIONAL SPECIFICATION.
Improved Sanitary Trap-gully for Streets and other Places.
JOSEPH JOHN PHILLIPS Gentleman 2 Zenoria Street, Dulwich, S.E. do hereby
declare the nature of this invention to be as follows:-
The object of this Invention is to remove as far as possible the insanitary condition
of the ordinary street gully now in use. For this purpose, I construct a gully-
chambor of iron stoneware or other material for the reception of the debris carried
down the gutter. The outlet from this chamber for the surface water is through a
syphon-trap, so constructed of iron or other material with an independant entrance
for the removal of any obstruction, to prevent the escape of sewer-gas, and afford
easy facilities to charge the syphon-trap with disinfecting substances.
Dated this 25th day of June 1888.

COMPLETE SPECIFICATION.
Improved Sanitary Trap gully for Streets and other Places.
I, JOSEPH JOHN PHILLIPS, Gentleman, of 2 Zenoria Street, Dulwich S.E. 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:-
The object of this invention is to remove as far as possible the insanitary condition
of the ordinary street gully now in use.
The drawing annexed is a vertical section of my improved sanitary trap gully. It
is constructed with a gully chamber A of any required shape and size of iron
stoneware or other suitable material for the reception of the debris carried down
the gutter.
The drawing shews the upper part of the chamber as made of iron and the bottom
of concrete.
The outlet A' from this gully chamber leads into a syphon trap B which is also of
iron stoneware or other suitable material.
I form the lower part of this trap preferably of earthenware and with two
passages B B passing from it at the top and leading to one opening formed through
the ordinary stone bottom C of the gutter. D is a cover closing this opening flush
with the upper surface of the stone C. Preferably a flat paving stone E with openings
through it corresponding to the passages B' B² is interposed as shewn between the
top of the earthenware trap B and the stone C so that the trap B may be made as
light as practicable. The partition F which passes across the trap is as shewn
formed in such manner that it can be lifted up through the passage B³ and removed
for cleaning or repairs—the lower part of the flap is also inade capable of turning
on a hinge joint at F' so that whenever there is a strong flow of water from the
gully chamber A it may yield and allow the water to flow away freely. The
passage B' is made to slope as shewn towards the outlet from the trap so that should
there be any obstruction at the outlet it may readily be removed if the cover D
is lifted.
Whenever the cover is lifted facility is also given for charging the bend of the
syphon trap with disinfecting fluids or substances.
The passage through the stone E which forms the continuation of the passage B¹
is ordinarily covered over at the top with a lid G as shown to prevent the passage
of sewer gas past the hanging partition F.

page_text: H is an arched guard placed in front of the mouth of the outlet A¹ from the
gully chamber A-it descends a distance below the bottom of the outlet and not
only serves as a second trap to prevent the escape of sower gas from the gully
grating but also forms a guard to hinder solid mitters from being carriad into
the outlet A' by the flow of water.
Having now particularly described and ascertained the nature of my smid inven-
tion and in what manner the same is to be performed declare that what I
claim is:-
1. The construction of trap gullies substantially as hereinbefore described and
illustrated in the drawing annexed.
2. The construction of the outlet trap with an opening into it at the top to give
ready access to the outlet end of the trap and permit of obstructions being removed
from it substantially as described.
3. The construction of the outlet trap with its partition readily removable and
capable of turning on a hinge joint substantially as described.
