PROVISIONAL SPECIFICATION.
Improvements in and relating to Chimney Pots.
We, FREDERICK DYE and JOHN WILLIAM WELLS of 176 Regent Street,
London, W., Engineers, do hereby declare the nature of this invention to be as
follows:-
In accordance with this invention means are provided in connection with chimney
pots by which down draught is prevented and the annoyance and inconvenience so
frequently experienced of smoke being forced into the rooms by a downward
current of air through the chimney, are entirely obviated.
The means provided are simple in construction, inexpensive in manufacture, and
most effective in action, whilst when it is required to sweep the chimney no
obstruction is caused to the passage of the sweeping brush.
According to this invention, we have attached to and placed around the chimney
pot a cylinder or tube of any suitable metal or material, slightly larger in internal
diameter than the outside of the chimney pot, which cylinder or tube extends in an
upward direction to a suitable height above the chimney pot. In said cylinder or
tube we arrange and place a similar disc or baffle plate for the purpose as aforesaid
of preventing any down draught. The diameter of. said disc or battle is such that
whilst of sufficient size to effect the purpose desired, space is left around same and
inside the cylinder or tube to permit of the upward passage of the smoke from the
chimney. The dise or baffle may be a fixture within the tube or cylinder or it
may be made adjustable by set screws or other suitable means. Or a suitable
number of vertical slots (say three) may be cut in the tube or cylinder and a
corresponding number of pins or arms be formed upon or attached to the disc
or baffle resting and working in the slots aforesaid. The slots extend upwardly
from a desired distance above the level of the chimney top proper (say about six
inches) so that in its normal position the disc or baffle will rest at such distance
above the chimney pot. No obstruction is then caused to the upward passage of"
the sweeping brush, and when the disc is fitted as above described in vertical slots
formed in the tube, the brush may even be passed further through and carry said
disc or battle with it the latter returning into its position of rest as the brush
descends.

Improvements in and relating to Chimney Pots.
We FREDERICK DYE and JOHN WILLIAM WELLS of 176 Regent Street,
London W., Engineers, 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 :-
In accordance with this invention means are provided in connection with
chimney pots by which down draught is prevented, and the annoyance and
inconvenience so frequently experienced by smoke being forced into the rooms by a
downward current of air through the chimney are entirely obviated. The meaus

in action, whilst when it is required to sweep the chimney no obstruction is caused
to the passage of the sweeping brush.
And in order that this invention may be fully understood and readily carried
into effect' we will now proceed to describe same with reference to the accompanying
drawings of which Fig. 1 is a side elevation of the exterior of the chimney pot
constructed with our improvements, Fig. 2 a sectional elevation, and Fig. 3 à plan
of the same.
Now in according to this invention we have attached to and placed around the
chimney pot a, a cylinder or tube of any suitable metal or material, slightly
larger in internal diameter than the outside of the chimney pot a a cylinder or tube b
of any suitable metal or material, slightly larger in internal diameter than the
outside of the chimney pot a which cylinder or tube extends in an upward
direction to a suitable height above the chimney pot a, to which latter the tube or
cylinder is connected by brackets c which hold same in position. In said cylinder
or tube b, we arrange and place a circular disc or baffle plate d for the purpose as
aforesaid of preventing any down draught. The diameter of said dise or baffle
plate d is such that whilst of sufficient size to effect the purpose desired, space is left
around same and inside the tube or cylinder to permit of the upward passage of
the smoke from the chimney. The disc or baffle may be a fixture within the tube
or cylinder b, or it may be made adjustable by set screws or other suitable means.
Or as shewn in the drawings, a suitable number of vertical slots e (say three) may
be cut in the tube or cylinder band a corresponding number of pins or arms
formed upon or attached to the disc or baffle d resting and working in the slots e
aforesaid. The slots e extend upwardly from a desired distance (say about 6 inches)
above the level of the chimney pot proper a so that in its normal position the disc
or baffled will rest at such distance above the chimney pot. No obstruction is then
caused to the upward passage of the sweeping brush and when the disc or baffle d
as above described and shewn in the drawings in vertical slots formed in the tube
the brush may even be passed further through and carry said disc or baffle with it,
the latter returning into its position of rest as the brush descends.
be
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The improvements in and relating to chimney pots substantially as and for the
purposes hereinbefore described and shewn in the drawings.
2. The arrangement and combination of tube or cylinder around the upper end
of the chimney pot proper with disc or baffle d therein (either fixed or adjustable)
substantially as hereinbefore described and shewn.
