PROVISIONAL SPECIFICATION.
An Improved Ventilator or Chimney Cowl.
I, WILLIAM JOHN TAYLOR, of 7 Brunswick Square, Southampton, in the
County of Hampshire, Accountant, do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved ventilator or chimney cowl which consists
of a series of cones with outside jackets of various shapes acting as conductors and
non-condensers of air and smoke enabling the same to retain its warmth and
tendency to rise until it has escaped the shaft into the open air and making a down
draft altogether impossible.
This ventilator or chimney cowl may be constructed of earthenware, iron, brass,
zinc or of any other metallic substance.
The advantages of my invention are as follows:→
Will fit any existing chimney pot thus not necessitating expense in brickwork.
No need of tall and dangerous shafts and an infallible cure is secured.
As a ventilator it prevents the steaming of shop and other windows, it admits no
down current or dust.
Effectually ventilates public or private buildings, ships cabins and all other places
where health and comfort is demanded.
It will be understood that the foregoing is given by way of illustration and that
the shapes materials and parts may be varied in many ways within the scope of my
invention.
Dated this 7th day of January 1893.

COMPLETE SPECIFICATION.
An Improved Ventilator or Chimney Cowl.
I, WILLIAM JOHN TAYLOR, of 7 Brunswick Square, Southampton, in the
County of Hampshire, Accountant, do hereby declare the nature of this invention

My invention relates to an improved ventilator or chimney cowl.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of ventilator.
Fig. 2, is an elevation of Fig. 1.
Fig. 3, is a vertical section of ventilator and chimney cowl..
Fig. 4, is an elevation of Fig. 3.
The up and down draughts are indicated by arrows.
This invention consists of a cone a surmounting a flanged topped shaft c or flue
the same having an outside jacket 6 standing off and yet to cover the sides of the
top and so arranged as to allow an up or down current of wind as indicated by
arrows to pass the smoke or air outlet and so act as to rapidly carry all smoke and
foul air away and making a down draught in the shaft altogether impossible.
This ventilator or chimney cowl may be constructed with stays or bars to connect
the various parts together of earthenware, iron, brass, zinc or of any other metallic
substance.
