IMPROVEMENTS IN VENTILATING DEVICES FOR HOUSE DRAINS
Year: 1884

page_text: I, JAMES BECKETT, of 3 Brougham Terrace, Crosshill, in the County of
Renfrew, Portioner, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN VENTILATING DEVICES FOR HOUSE DRAINS," to bo as
follows:-
This Invention relates to improved devices to be fitted in connection with house
drains for ventilating them.
The improved ventilating device consists of a horizontal pipe which is open at
the upper side, or is formed of U-shape in cross section and which is fitted at any
convenient position outside the house to form a portion of the length of the house
drain pipe or branch leading to the main sewer, the ventilating pipe being
connected to the ordinary round pipes of the drain by the usual spigot and faucet
or other joints. The bottom of the U-shaped pipe is formed with ribs or flanges
which serve as a seat for the pipe, and the vertical sides of the pipes may also be
flanged longitudinally.
From the upper sides of the pipe, at whatever depth, to the surface of the
ground, a well of brick work is built and is covered by an open grating; and any
foul air or sewer gas, flowing back from the main sewer towards the house drain,
escapes up through the open top or upper side of the U-shaped pipes and through
the well and grating to the open air. The ventilating opening may also form an
outlet for surface water. By laying a number of these pipes continuously, a
practically open drain is formed, where sewer gas cannot lodge.
When the house drain is carried through a garden or other open ground, the
well of brickwork may be dispensed with, the vertical sides of the U-shaped pipe
being carried to a sufficient height, and being made to form a seat for the grating
which is fitted over tho ventilating opening. A gentle slope may be given to the
ground in the immediate neighbourhood to carry surface drainage down to the
grating, and to avoid carrying up the sides of the ventilating pipe to the general
ground level. The house drain thus formed being always open to sight, any
obstruction or choking can be at once detected, and being easily accessible can be
repaired at little expense.

page_text: I, JAMES BECKETT, of 3 Brougham. Terrace, Crosshill, in the county of
Renfrew, Portioner, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN VENTILATING DEVICES FOR HOUSE DRAINS," 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 improved devices to be fitted in connection with house
drains for ventilating them, and it is illustrated by the accompanying drawings,
in which figures 1 and 2 are respectively a longitudinal vertical section and a
transverse vertical section of one modification of the improved drain pipe; and
figures 3 and 4 are similar views of another modification.
The improved ventilating device consists of a horizontal pipe A which is open
at the upper side A', or is formed of U-shape in cross section, and which is fitted
at any convenient position outside the house to form a portion of the length of the
house drain pipe or branch leading to the main sewer, the ventilating pipe A
being connected to the ordinary round pipes B of the drain as shown, by the usual
spigot and faucet or other joints. The bottom of the U-shaped pipe is forined
with a flat base to serve as a seat for the pipe, and to prevent rocking the vertical
sides A of the pipes A may also be flanged longitudinally. From the upper sides A
of the pipe, at whatever depth, to the surface of the ground, a well C of brick work
is built and is covered by an open grating D; and any foul air or sewer gas flowing
back from the main sewer towars the house drain is diluted with the fresh air in
these open pipes and well and escapes up through the open top or upper side of the
U-shaped pipes A and through the well C and grating D to the open air. The
ventilating opening may also form an outlet for surface water drainage.
laying a number of these pipes continuously, a practically open drain is formed
where sewer gas cannot lodge. When the house drain is carried through a garden
or other open ground, the well of brickwork C may be dispensed with, the vertical
sides A' of the U-shaped pipe A being carried to a sufficient height, and being made
to form a sent for the grating D which is fitted over the ventilating opening, as is
shown in figures 3 and 4. A gentle slope may be given to the ground in the
immediate neighbourhood as at E to carry surface drainage down the grating D,"
and to avoid carrying up the sides of the ventilating pipe to the general ground
level. The house drain thus formed being always open to sight, any obstruction
or choking can be at once detected, and being easily accessible can be repaired at
little expense.
By
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,
First. The arrangement in a house drain of an open pipe or series of pipes of
U-section forming part of such drain in combination with a well reaching from
such pipe to the ground level, substantially as herein described and illustrated.
Second. The open pipe of U section forming an integral part of a house drain,
substantially as and for the purpose herein set forth.
