I cover from view. by means of a pierced plain or ornamented grate, or in
other suitable or convenient manner, and at about the centre of the length of

page_text: the pipe I cut away a portion thereof and attach a chamber, which is divided
in two parts by a partition lying at right angles to the length of the pipe. To
the upper part of the chamber I attach a vertical pipe of the same diameter
as the pipes in the floor. The vertical pipe I insert in one of the walls of the
building, or it may form a hollow pillar where pillars are used to support tho
floor above; the top of the pipe or pillar projects into a similar chamber to
the one furnished to the horizontal pipe in the first floor, the end of the pipe
or pillar stands up a few inches above the bottom of the chamber, and from
the bottom of the chamber one or more pipes proceed to each room, the other
ends of the pipes terminating in one or more orifices in the ceilings of such
rooms; the upper part of the second chamber is connected to a similar vertical
pipe or pillar, as before mentioned. The pipes and chambers being repeated
in each story, the vertical pipe or pipes are then continued from the top ceiling
to the ridge of the roof, where it or they terminate a few inches upward from
the bottom of a tube or tubes of a larger diameter which projects above the
roof outside. This tube is also surrounded with a still larger tube, the bottom
of which is set a few inches clear above the roof, and the top is furnished with
a cowl or cone to prevent any downward draught.
My Invention is also applicable to the ventilation of houses and other
buildings or structures which are already erected or constructed.

NOW KNOW YE, that I, the said William Tebbutt, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawings, and to
the letters and figures marked thereon, that is to say :-
My Invention consists of the arrangement and combination of parts consti-
tuting. the apparatus constructed as follows:-In setting forth my Invention
I proceed to describe it as applied to a house or like structure. I premise,
for convenience of description, that a house or other like structure is about
to be built, and it is desired to ventilate the same, for this purpose.I proceed
in the following manner-In the floor level with the street I insert a pipe
extending from the front side of the house to the, back thereof; the ends of
this pipe I. cover from view by means of a pierced plain or ornamented grate,
or in other suitable or convenient manner, and at about the centre of the
length of the pipe I cut away a portion thereof and attach a chamber, which
is divided in two parts by a partition lying- at right angles to the length of
the pipe. To the upper part of the chamber I attach a vertical pipe of the
same diameter as the pipe or pipes in the floor; this vertical pipe I insert in
one of the walls of the building, or it may form a hollow pillar where pillars
are used to support the floor above; the top of the pipe or pillar projects into
a similar chamber to the one appertaining to the horizontal pipe in the first
floor, the end of the pipe or pillar stands up a few inches above the bottom of
the chamber, and from the bottom of the chamber one or more pipes proceed
to each room; the other ends of the pipes terminate in one or more orifices
in the ceilings of such rooms.. The upper part of the second chamber is
connected to a similar vertical pipe or pillar, as before mentioned. The pipes
and, chamber or chambers are repeated in each storey. The vertical pipe or
pipes is or are then continued from the top ceiling to the ridge of the roof,
where it or they terminate a few inches upward from the bottom of a tube or
tubes of a larger diameter which projects above the roof outside. This tube

particularly to describe the manner of performing the same with reference to
the accompanying Drawings.

DESCRIPTION OF THE DRAWINGS.
The Drawing represents the section of a house shewn as if cut through
from front to back, and shews the arrangement of my ventilating apparatus as
applied thereto, having the vertical pipes in the central partition wall: In the
floor, level with the street, I insert a pipe A extending from the front side of
the house to the back thereof, the outer ends of this pipe I cover from view
by means of a pierced plain or ornamental grate B, and at the centre or other
convénient portion of the length of the pipe I cut away a portion of the pipe
and insert and attach a chamber C, which is divided in two parts by a partition
placed at right angles to the length of the pipe A. To the upper part of the
chamber C, I attach a vertical pipe D of the sanie diameter as the pipe A; the
partition of the chamber C may be continued up the pipe D for its whole
length, or the partition may extend only a few inches up the pipe. I insert
the pipe D in one of the walls of the building where most convenient, or the
pipe may form a pillar of a circular or other shaped section. The outside of
this pillar may be of a plain or ornamental character, and may form a support
for the floor above. The top of the pipe or pillar projects into a chamber E,
which is similar to the chamber C. The top end of the pipe or pillar D stands
up a few inches above the bottom of the chamber E, and from the bottom of
the chamber E one or more pipes proceed to each room, the end of the pipe
or pipes farthest from the chamber E terminating in one or more orifices G in
the ceilings of such rooms; these said orifices may form part of, or may be
hidden by a perforated, plain, or ornamented grating inserted in the ceilings.
The upper part of the chamber E is connected to another vertical pipe or
pillar H, and the pipes and chambers are repeated in each storey, and the
vertical pipe or pipes are then continued from the ceiling of the top storey to
the ridge of the roof, where it or they terminate a few inches upward from the
bottom of a tube or tubes I of a larger diameter than the aforesaid vertical
pipe or pipes; this tube or tubes I projects above the roof outside. The tube 1
is also surrounded by a still larger tube K, the bottom of which is set a few

page_text: inches above the roof, and the top is furnished with a cowl or cone to prevent
any downward draught.
The ventilation of the building to which this my apparatus is applied is
effected in the following manner:-The air rushes along the pipe A from
either side of the house, where it meets with the partition in the chamber C,
which turns the draught up the pipe D; if it were not for this partition the
wind, when it blows strongly from one side of the house, would be liable to
pass through the pipe A and out at the other side. As the air passes up the
vertical pipes it draws out the heated, impure, and noxious air and gases through
the orifices G in the ceilings along the pipes F and up the vertical pipes
into the tube I, from whence it escapes through the outer tube K into the
atmosphere.
Although I have here, for example, illustrated my Invention in its appli-
cation to the ventilation of dwelling rooms, it will be fully apparent that my
Invention is also equally applicable to the ventilation of other buildings or
structures.
And having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that what I claim as new is,
the arrangement and combination of parts, herein-before described, constituting
apparatus for ventilating dwelling rooms and other places, and for removing
foul or noxious air therefrom.
In witness whereof, I, the said William Tebbutt, have hereunto set my
hand and seal, this Eighteenth day of November, in the year of our
Lord One thousand eight hundred and sixty-one.
