PROVISIONAL SPECIFICATION.
An Improved Intercepting or Disconnecting Trap for Drains and
Sewers.
I, THOMAS HUGHES, of 2, Buckingham Villas, Hampton, Middlesex, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved intercepting or disconnecting trap for
drains or sewers, and has for its object to provide better facilities for cleaning.
out the drains and sewers, to improve the ventilation and to dispense with the
usual costly brick inspection chambers.
For this purpose my improved trap consists of a vertical portion provided.
with the usual end inlet and formed with a side branch leading to an upper
inlet opening to which is connected a pipe, carried up in a straight line with.
the drain to the surface and used for removing any obstruction in the trap.
The said vertical portion leads at its lower end into an upwardly curved exten-.
tion or branch forming the outlet, the connection between the two portions:
being strengthened by a rib, and the usual water seal being formed to the required
depth by the clip formed between the junction of the said portions.
The upper part of the curved portion is formed with an opening or socket
placed at an angle therewith extending towards the vertical portion, and to the
said socket is connected a tube leading in a straight line to the surface and used
for cleaning out purposes thus obviating the necessity of brick inspection
chambers.
By thus using pipes of uniform size a uniform current of air through the
same is produced and the ventilation of the drains is improved.

An Improved Intercepting or Disconnecting Trap for Drains and
Sewers.
I, THOMAS HUGHES, of 2, Buckingham Villas, Hampton, Middlesex, 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 an improved intercepting or disconnecting trap for

page_text: drains and sewers, the object of which is to provide better facilities for cleaning
out the drains and sewers over those hitherto constructed, to improve the venti-
lation, and to dispense with the usual costly brick inspection chambers.
According to my invention the said trap consists of a vertical tubular portion
provided with the usual end inlet and socket and formed with a side branch
leading to an upper vertical inlet and socket to which is jointed a pipe carried
up in a straight line with the drain to the surface and used for removing any
obstruction in the trap.
The lower end of the first named vertical portion leads into an upwardly
curved extension or branch forming the outlet, the connection between the two
being strengthened by an outer rib, and the usual water seal being provided by
the dip formed between the junction of the said portions.
The upper part of the curved outlet is formed with a socketed opening placed
at an angle therewith inclining towards the vertical portion, and to the said
socket is jointed a tube leading in a straight line to the surface and used for
cleaning out purposes thus obviating the necessity of brick inspection chambers.
By thus using pipes of uniform size a uniform current of air through the
same is produced, and the ventilation of the drains improved.
And in order to clearly understand my invention reference is had to the
accompanying sheet of drawings in which Fig. 1 is a longitudinal vertical sec-
tion of my improved trap, and Fig. 2 is a cross section through the vertical
tubular portion and side branch. Fig. 3 is a sectional plan through the vertical
and horizontal branches, and Fig. 4 is a plan.
a is the vertical tubular portion formed with the inlet opening and socket a¹,
and is the side branch formed with the inlet opening and socket 1, to which
is jointed a pipe used for removing obstructions. c is the curved extension
leading from the lower end of the portion a and forming the outlet to the drain
or sewer. The branches and e which are of equal diameter are provided with
the strengthening rib in the angle formed by the dip d for providing the
usual water seal. e is the opening in the upper part of the extension leading
to the socket branch f formed at an angle inclining towards the portion a, and
is the tube jointed to the said socket and leading in a straight line to the sur-
The said tube g is used for cleaning out purposes and obviates the neces-
sity of employing a brick inspection chamber.
.face.
This improved trap may be made of stoneware, iron, glass, or other suitable
material either in one piece or in sections and may be formed right or left-
handed. The advantages of my improved traps are that there is no possible
chance of sewer gas escaping into the atmosphere and there is a clear air space
above the surface of the water seal which permits of a better circulation of
fresh air in the drain than is the case when using brick chambers. They can
also be cleared with an ordinary long rod, and there is no possibility of the
subsoil leaking into the drain when they are laid in wet ground. They can
likewise be laid and easily cleaned out at any depth and the necessity for pump-
ing out the contents of a brick chamber is obviated.
There are also no big cast iron covers required thus preventing the entrance
of rain water, and they reduce the cost of laying house drains to a minimum.
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:-
(Claim 1). The improved intercepting or disconnecting trap for drains and
sewers comprising a vertical tubular inlet formed with a side branch leading to
a vertical pipe used for removing obstructions and an upwardly curved branch
or outlet leading from the inlet tube and formed with an inclined branch_con-
nected with a tube leading in a straight line to the surface and used for clean-
ing-out purposes, substantially as described.
(Claim 2). In an intercepting or disconnecting trap for drains and sewers the

page_text: combination of a vertical tubular inlet portion a with socket a¹, a side branch b
with socket and pipe 2 a curved extension of equal diameter to the por-
tion a, a rib d and dip d', an opening e in the extension c, an inclined socketed
branch f, and a tube y connected thereto, substantially as described, and shown,
and for the purposes specified.
