New or Improved Means or Method of Ventilating Chimney-pots,
Chimney Stacks and Buildings.
I, ROBERT INGHAM, of Marl House, Huncoat, near Accrington, in the County of
Lancaster, Builder, do hereby declare the nature of this invention to be as
follows:
This invention relates to a new or improved means or method of ventilating
chimney pots, chimney stacks and buildings.
My invention as applied to a chimney pot is designed to effectually cure down
draughts and smoky chimneys, the peculiar and novel construction of the chimney
pot according to my invention rendering it impossible for the whirlwinds or back
currents of air at the top of the pot in turbulent or boisterous weather to have
any material effect upon the smoke or heated gases arising from the chimney or
flue, as would in any marked degree be liable to create down draughts, such back
currents being checked in their vigour, by the means which I provide, while the
smoke ascending from the chimney pot is allowed to pass away unaffected thereby.
To accomplish this, I expand the sides of the chimney pot at any convenient
distance from the top and for any desired portion of its length, and then contract
the pot to its normal size or thereabouts. This expansion may be circular,
diamond, oval, square rectangular or of any suitable shape, and may be applied
to a round or square pot or a pot of other formation, the shape of the expansion
being preferably such as will be most suitable for the particular construction or
shape of the chimney pot as the case may be.
Within the interior of this expanded portion, and formed either integral with
the pot during the course of manufacture, or secured thereto afterwards, I place
or fix a V or other suitably or similarly shaped baffle plate, diaphragm, or guard,
the projecting portions of the top edges of the V or similar shaped partition pro-
jecting beyond and aback of the contraction or outlet end of the chimney pot,
and within the expanded portion thereof, and at a suitable distance from the neck
or contraction as to permit of the free exit of the smoke and heated gases arising
from the chimney to the open air, and yet any down currents of air will be com-
pelled to follow the internal surface of the V partition, and emerge from an outlet
or outlets formed at the bottom of the V partition, to the external atmosphere
The projection of the top edges of the ✓ partition within the expanded sides of
the chimney pot, so as to prevent the down draughts having any material in-
fluence on the up currents, is an important and essential feature of my invention.
Rain entering the chimney pot will be obliged to follow the V partition, and run
out at the opening at the bottom, the chimney thus being kept perfectly dry.
In a modification, the expansion may be continued uniformally to the bottom
of the pot, the V or like partition being inserted with its top edges close to, and
beyond the contraction of the pot, and within the expanded portion, in the man-
ner already described
My invention is also applicable as a ventilator to buildings of every description
where ventilators are required, and it may take divers forms, the same essential

page_text: feature still existing. In one form, the exterior case of the ventilator may be
square or round of any desired dimensions, and provided with a top flange. The
top edges of the V partition come underneath the top flange, and are within a
suitable distance thereof, so as to allow of the free escape of foul air from the
interior of the building, but entirely obstructing the entrance of draughts and
rain. The foul and fetid air from the building will pass through a ventilator of
this description far more readily than through those constructed with side open-
ings and others of the old type.

New or Improved Means or Method of Ventilating Chimney-pots,
Chimney Stacks and Buildings.
I, ROBERT INGHAM, of Marl House, Huncoat, near Accrington, in the County of
Lancaster, Builder, 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 new or improved means or method of ventilating
chimney pots chimney stacks and buildings.
My invention as applied to a chimney pot is designed to effectually cure down
draughts and smoky chimneys, the peculiar and novel construction of the chimney
pot according to my invention rendering it impossible for the whirlwinds or back
currents of air at the top of the pot in turbulent or boisterous weather to have
any material effect upon the smoke or heated gases arising from the chimney or
flue, as would in any marked degree be liable to create down draughts, such back
currents being checked in their vigour by the means which I provide, while the
smoke from the chimney pot is allowed to pass away unaffected thereby.
:
To accomplish this, I expand the sides of the chimney pot at any convenient
distance from the top, and for any desired portion of its length, and then contract
the pot to its normal size, or thereabouts. This expansion may be circular,
diamond, oval, square, rectangular or of any suitable shape, and may be applied
to a round or square pot, or a pot of other formation, the shape of the expansion
being preferably such as will be most suitable for the particular construction or
shape of the chimney pot as the case may be.
Within the interior of this expanded portion and formed either integral with
the pot during the course of manufacture, or secured thereto afterwards, I place
or fix a V shaped or other suitably or similarly shaped baffle plate, diaphragm,
or guard, the projecting portions of the top edges of the V or similar shaped
partition projecting beyond and aback of the contraction or outlet end of the
chimney pot, and within the expanded portion thereof, and at a suitable distance
from the neck or contraction, so as to permit of the free exit of the smoke or
heated gases arising from the chimney to the open air, and yet any down cur-
rents of air will be compelled to follow the internal surface of the ✓ partition,
and emerge from an outlet or outlets formed at the bottom of the V partition
to the external atmosphere. The projection of the top of the V partition within
the expanded sides of the chimney pot, so as to prevent the downdraughts having
any materiál influence on the up currents is an important and essential feature of
my invention. Rain entering the chimney pot will be obliged to follow the V
partition, and run out at the opening at the bottom, the chimney being thus kept
perfectly dry.

page_text: In a modification, the expansion may be continued uniformally to the bottom
of the pot, the V or like partition being made with its top edges close to and
beyond the contraction of the pot, and within the expanded portion, in the man-
ner already described
My invention is also applicable as a ventilator to buildings of every description
where ventilators are required, and it may take divers forms, the same essential
feature still existing. In one form, the exterior case of the ventilator may be
square or round of any desired dimensions, and provided with a top flange. The
top edges of the V partition come underneath the top flange, and are within a
suitable distance thereof, so as to allow of the free escape of foul air from the
interior of the building, but entirely obstructing the entrance of draughts and
rain. The foul and fetid air from the building will pass through a ventilator of
this description far more readily than through those constructed with side open-
ings and others of the old type,
In the accompanying drawings, Fig. 1 is a sectional elevation of a square
chimney pot, constructed in accordance with my invention.
The pot may be made in one piece, or constructed in two portions A and B.
The piece A fits on the neck of the piece B. Below this point, the pot is consider-
ably expanded as shewn at C. Within the expanded portion at a suitable dis-
tance from the expanded sides, I form a V shaped diaphragm or partition D,
either integral with the pot, or constructed separately, and afterwards secured
thereto. At the bottom of the V, I make a hole or outlet, such as D¹. Any
down currents of air or rain entering the chimney pot will be checked in their
violence, and will chiefly pass through the outlet D. Those which may succeed in
passing the sides of the pot at E will encounter the baffle plates F, and emerge at
the outlets G.
At its base, the pot may be formed with a flat bottom as shewn at H to bed on
the stack K, and also with an extension J to fit into the flue.
Fig. 2 is a similar view of a round chimney pot, which is constructed on similar
lines to Fig. 1 with the exception that the top piece. A is here formed in one piece
with the pot.
My invention as applied to a ventilator is shewn in Fig. 3.
L are the air inlets, M the V shaped diaphragm or partition, which checks the
inrush of air, but permits of the escape of foul air from the building. O is an out-
let for the escape of turbulent air currents or rain water.
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:
A chimney pot having expanded sides, and constructed with a V or other
similarly shaped diaphragm or partition such as D, whose top edges project with-
in the expanded sides of the pot, while at the bottom it is provided with an outlet
or outlets for the escape of downdraughts and rain water, substantially as
described and shewn with reference to Figs. 1 and 2 of the accompanying drawings.
2. In combination with my improved construction of chimney pot claimed in
the preceding claim,, the baffle plates F and outlets G, substantially as and for
the purpose described.
3. The improved construction of ventilator as described and shewn with reference
to Fig. 3 of the accompanying drawings.
