PROVISIONAL SPECIFICATION.
An Improved Wind-guard for Tops of Flues or Chimneys.
I, KNOWLES, EDGE, of; 46 Raphael Street, Brownlowfold, Bolton in the County of
Lancaster, Manufacturing Chemist do hereby declare the nature of this invention to
be as follows:-
This invention relates to a new and improved appliance to the top of any flue or
chimney used for ventilating purposes or for conveying away the products of com-
bustion.
It may be described by. reference to the accompanying drawings as follows:-
:
A in figures 1, 2, and 3 represents the upper portion of a flue or chimney. B in
figures 1, 2, and-3, is a detachable ring, oscillating on two pivots or studs attached to
or projecting from A. The said pivots or studs are shewn in figure 3 at E and E¹.
Cin figures 2 and 3.is a detachable ring, oscillating on two pivots.or studs attached
to and projecting from B, and these studs or pivots are shewn in figure 3 at F and F¹.
D is a wide tube securely attached at its lower part to the ring C, as shown in figure 2
dotted line at C-or the lower part of D may be utilised in place of the ring C.
The tube D and rings B and C may be circular or any suitable shape. This
arrangement allows the wind guard to rise on all sides in any direction, and by
applying it to the top of any flue or chimney the exit for the gases or smoke is
always shielded on the side against which the wind-currents strike. A wind-current
of moderate force causes the wind-guard to rise in any direction, as shewn in
figure 1, and as the wind passes over the highest part (as shewn by arrow figure 1)
the smoke is not only carried away, but a gentle induced draught is also produced-
preventing downdraughts and insuring ventilation in those flues or chimneys where
no fires are burning.
COMPLETE SPECIFICATION.
An Improved Wind-guard for Tops of Flues or Chimneys.
I KNOWLES EDGE 46 Raphael Street Bolton in the County of Lancashire Manu-
facturing Chemist 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 a new and improved appliance to the tops of flues or
chimneys used for ventilating purposes or for conveying away the products of com-
bustion. It may be described by reference to the drawings (left with the application
for Provisional Protection) as follows.
A in figures 1. 2. and 3 represents the upper portion of a flue or chimney. B in
figures 1. 2 and 3 is a detachable ring or frame oscillating on two pivots or studs
(attached to B or projecting from A as the case may be). The said studs are shown
at E and E' in figure 3.
C in figures 2 and 3 is a detachable ring or frame oscillating on two pivots or studs
(attached to C or projecting from B as the case may be) and these studs or pivots are
shewn at F and F in figure 3.
D is a wide tube securely attached at the lower part to the ring or frame () as
shewn in figure 2 (dotted line at C) or the lower part of D may be utilized in place of
the ring or frame Č.
The tube D and the rings or frames B and C may be circular or other suitablę
shape, and may be made of any suitable metal or other materials,

page_text: This arrangement allows the windguard to rise in any direction under the impulse
of a wind current, thereby shielding the top of the flue or chimney from the wind as
shewn in Figure 1 for as the wind passes over the higliest part (as shewn by arrow in
figure 1) the smoke is carried away, and an induced draught is. produced which
insures ventilation in those flues or chimneys where there are no fires burning.
It will be seen that the working parts of the windguard (afore described) are all
outside the flue or chimney passage, and as the said passage is quite open to the top,
it is possible to always sweep the flue or chimney throughout from below:
Having now particularly described and ascertained the nature of my said. inven-
tion, and in what manner the same is to be performed I declare. that what. I
claim' is
1. A windguard for tops of flues or chimneys in which the improvements, are;.
The ring or frame. B. which oscillates on two pivots or studs E and E at two outer
centres of the tube A.
2. The ring or frame C-or instead thereof the lower part of D-which oscillates
on two pivots or studs at two outer centres of the ring, or frame B.
די
3. The adjustment by weight and size of the above parts to each other so that the
windguard oscillates in the direction of a wind. current, and is: inoperative and at resti
in still air..
