Improvements in Gullies, Traps, and in Apparatus for Ventilating
Drains and the like.
HENRY CLARK of no occupation No. 2 Cross Woodbine Street Dewsbury
Yorkshire do hereby declare the nature of this invention to be as follows:-
This invention relates to drains only. Among the objects of this invention is to
produce a means of preventing the passage of sewer gas, stench or rats from one
part of a system of drainage to another and absolutely to prevent stench or sewer
gas from rising and accumulating at the higher levels. And to provide sufficient
outlets for stench and inlets for fresh air as to prevent the accumulation of stench
or sewer gas in any part of a drainage system whatever. And to render the use of
gullies, syphons or other traps with a water seal unnecessary and thus prevent the
stench which arises from the large quantities of stagnant water which continually
stand in large gullies and traps.
The accompanying drawing forming part of this Specification scale 14″ inches
to 12" inches.
Fig. 1 is a section showing bottom and top of three drain pipes the second pipe is
the trap.
Fig. 2 is a section showing bottom and top of street gully and trap.
The first pipe is an ordinary 12" drain pipe with a junction laid upwards the same
size to serve as an inlet for fresh air.
The second pipe the trap is a pipe square at the top, the same shape at the
bottom as the pipe to which it is connected, without flang the socket for the first
pipe being formed inside to allow of an ordinary pipe fitting in, continueing the
same shape and size internally but twice the thickness to the falling door A. to stop
the stench, and from that part to the end of the pipe as much larger as the thickness
of the pipe with square stench outlet at the top, the doors to be inade of galvanized
cast or sheet iron, fixed to " inch wrought iron shaft of sufficient weight to open
when the sewage water passes, the shaft to work in carriage and cap with brasses
fixed in the sides of pipe.
The third pipe is a connecting pipe square at the top and the same shape at the
bottom as the pipe to which it is connected to run out the same size and shape both
top and bottom as the pipe at the other end to enable it to fit into the socket of an
ordinary pipe the same size and shape, and may be made in two equal parts top and
bottom to enable the pipes to be connected to an existing drain the pipes may be
round culvert or any shape only the three pipes are the same shape at the bottom
and can be made of iron earthenware or other material.
Gullies. The gully for connecting the stench preventer has slanting opening
unt raped with rebated opening into gully for fine grate B to fix in with cement to
prevent solid matter from entering the drain.
For water closet or flushing closet connection all the three pipes will be required,
with an open grate at the surface for the fresh air inlet over the first pipe,
and closed grate over the stench outlet pipe with 4" inch pipes to wall of
building to which it is connected and carried up to the roof by an ordinary
iron pipe to carry the stench from drain besides the stench outlet from soil
pipe.
What I consider to be new is the use of the first pipe as an inlet ventilation shaft
in the possition in which it is placed the second and third pipes in their entirety all
complete.
The untraped opening to allow the water to pass from the gullies and the grate
fixed with cement to prevent solid matter from entering the drain. The inlet shaft

COMPLETE SPECIFICATION.
Improvements in Gullies, Traps, and in Apparatus for Ventilating
Drains and the like.
I HENRY CLARK of no occupation No. 2 Cross Woodbine Street Dewsbury in
the County of Yorkshire 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 drains only. Among the objects of this invention is to
produce a means of preventing the passage of sewer gas, stench, or rats from one
part of a system of drainage to another, and absolutely to prevent stench or sewer
gas from rising and accumulating at the higher levels, and to provide sufficient
outlets for stench and inlets for fresh air as to prevent the accumulation of stench
or sewer gas in any part of a drainage system whatever. And to render the use
of gullies syphons or other traps with a water seal unnecessary and thus prevent
the stench which arises from the large quantities of stagnant water which continually
stand in the large gullies and traps.
The drawings left with the Provisional Specification scale 1" inches in
12" inches.
Fig. is a section showing bottom and top of three drain pipes the second pipe
is the trap.
Fig. 2 is a section showing bottom and top of street gully and trap connected.
The first pipe is an ordinary 12" drain pipe with junction the same size laid
upwards to serve as an inlet for fresh air.
The second pipe the trap is a pipe square at the top the same shape at the
bottom as the pipe to which it is connected, without flang, the socket for the first
pipe being formed inside to allow of an ordinary pipe fitting in, the pipe continuing
the same shape and size internally but twice the thickness to the falling door A to
stop the stench, and from that part to the end of the pipe as much larger as the
thickness of the pipe, with square stench outlet at the top the same size as the trap.
The doors to be made of copper, galvanized, cast, or sheet iron, fixed to inch (or
larger for larger sized pipes) wrought iron shaft the door and shaft to be of
sufficient weight to open and close when the sewage water passes. The shaft and
door to work in dovetailed carriage and cap with or without brasses with flang
outside, fixed in dovetailed openings in the sides of pipes, the broad end of the
tail inside and the flang outside to keep the carriage and cap fixed firmly in
its place.
The third pipe is a connecting pipe, square at the top and the same shape at the
bottom as the pipe to which it is connected, to run out the same size and shape
both top and bottom as the pipe at the other end to enable it to fit into the socket
of an ordinary pipe the same size and shape, and may be made in two equal parts
top and bottom to enable the pipes to be connected to an existing drain, and may
be round, oval, culvert, or any shape, only the three pipes are the same shape at the
bottom as the pipes to which they are connected, and can be made of iron, glazed
earthenware, or other material.
Gullies. The gully has slanting opening untraped with rebated opening into
gully for fine grate B to be fixed in with cement or other substance, to prevent
solid matter from entering the drain, and may be any size either for street
house, or any other connection, in street gullies the trap may either have

page_text: open grate or air tight cover over where there is danger of the accumulation
of stench.
In use for a main drainage system the first trap apparatus should be fixed
not far from the outfall or commencement of the drain, the trap will compel
the stench to come out at the outlet, the natural air current will enter at the
inlet shaft behind the door and continue to the next trap apparatus higher
up the drain and come out at the next outlet shaft. The traps may be fixed
any distance apart but there will only require one inlet for fresh air for one
section, all junctions for cross streets or roads must commence with the trap,
the outlet for stench may either have an open grate at the top or in most cases
an air tight cover allowing the stench to continue to the next stench outlet in the
main drain, where there is danger of the accumulation of stench in any section
an open grate should not be used but the stench should be conveyed away
by means of pipes and a shaft or chimney to let out the stench above the
buildings. When the three pipes with the trap are connected to brick drains they
should be made so that the ends of the first and third pipes will connect to the
brickwork.
For water closet or flushing closet connection all the three pipes will be required
with an open grate at the surface for fresh air inlet over the first pipe and an air
between
tight cover over the stench outlet, with 4" pipes to commence in the space
the top of trap and air tight cover and continue to the wall of building to
which it is connected and carried up to the roof by an ordinary iron pipe
to carry the stench from drain besides the stench outlet pipe carried from the
soil pipe.
For a house connection only the second and third pipes will be required with or
without gully, the sink pipe emptying itself onto a dish stone or fine grate con-
necting to the trap with a bend, the opening over the trap to be walled to the
ground level with air tight cover over with outlet pipe to carry away the stench
as in water closet connection. When two or more house connections are on one
branch drain there will only require one outlet for the furthest from the drain, when
house drains pass under the buildings all the three pipes will be required at the
entrance, and a second trap at the other side of the building to cause a current of
air under and prevent any stench from entering.
For any other kind of connection it will be necessary to have the pipes so laid
that the inlet for fresh air will be at the lowest part and the outlet for stench at
the highest or furthest end from the drains and in all cases where a drain passes
under any buildings there must be an outlet for stench and an inlet for fresh air at
the main drain side and an outlet for stench at the other side.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
1. A trap apparatus for main drainage (without water scal) with inlet for fresh
air and outlet for stench.
2. The use of the first pipe in the possition in which it is placed as an inlet
5 ventilation shaft for fresh air; the second and third pipes in their entirety all
complete, and the removable door fixed to the shaft working in carriage and cap
with or without brasses.
3. The fine grate fixed with cement or other substance in the untraped opening
in the gullies.
