I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6. Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middle-ex, Civil Engineer, do hereby declare the nature of this invention
to be as follows
In revolving chimney cowl-, (cowls for preventing down draught, ventilators and
the like) there is this apparent drawback that the free movement of the cowl
becomes very soon hindered by soot or moisture in that the soot settles on the
points of suspension or revolution, or else these latter become rusted up.
The object of this invention is to prevent, in the most practical manner, this
obstruction by soot or rust.
This is obtained by suspen ling the chimney or other similar cowl by means of a
projecting flange in such a way that it is entirely guarded against or removed from
the action of both soot and moisture.
The revolving cowl is suspended on a spindle which has the above mentioned
additional support or flange at its upper end. This latter rests on a ring or flange
and this is carried by a conical cover, which for its part is supported by the
chimney pot.
In order that the position of the revolving chimney cowl may be altered
according to the direction of the wind, the spindle may also be provided with a
wind vane.
The revolving chimney cowl may also be provided with an
Archimedean, spiral or the like screw without thereby altering anything in the
essence of this invention.
In order to diminish friction between the projecting flange and the ring or flange
serving as the guide bed, several balls capable of rolling freely may be inserted
between the same onto which then the weight of the revolving cowl is transferred.
By means of the above described extremely simple device, the points of suspension
or revolution of the chimney cowl are completely protected, not only against soot
and smoke, but also against rain or other deposit.

COMPLETE SPECIFICATION.
Improvements in or connected with Chimney Cowls or other similar
Cowls.
A communication by HERMANN FAULHABER, of Swabian Hall, in the Kingdom
of Würtemberg, Clergyman.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E., of the Agency for
6 Bank Street,
Foreign Patent Solicitors, 6 Lon Street Liverpool &
Manchester, both in the County of Lancaster & 323 High Holborn in the
County of Middlesex Civil Engineer do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly de-cribed and
ascertained in and by the following statement :—
In revolving chimney cowls (cowls for preventing down draught, ventilators

page_text: and the like) there is this apparent drawback that the free movement of the
cowl becomes very soon hindered by either soot or moisture, in that the soot
settles on the points of suspension or revolution, or else these latter become
rusted up.
The object of this invention is to prevent, in the most practical manner, this
obstruction by soot or rust.
This is obtained by suspending the chimney or other similar cowl by means of a
projecting flange in such a way that it is entirely guarded against or removed from
the action of both soot and moisture.
A cowl according to this invention is shown on the accompanying sheet of
drawings.
Figure 1 shows one form of construction, and
Figure 2 is a modified form.
The revolving cowl II in Figure 1 is suspended on a spindle O which has the
above mentioned additional support or flange B at its upper end, which rests on
a ring or flange C. The flange B is attached to the spindle by means of a
nut . The ring or flange C is carried by a conical cover D, which is supported
by stays attached to the chimney pot.
In order that the points of suspension may be protected, this cover is further
provided with a bottom plate E, through the centre of which the spindle O passes.
The spindle O is connected with the cowl H by means of the arms o.
The
revolving cowl H is entirely closed above by the covering plate F, in order that
soot and smoke may not, by any means, reach the points of suspension. As is
easily seen from the drawing, the points of suspension are fully protected by
means of this extremely simple and durable arrangement, on the one hand against
soot or smoke, and, on the other hand, by means of the cover D, against rain.
If it be desired to provide the cowl with a wind vane, the spindle O, as shown in
Figure 1, is carried through the cover D, and provided with a wind vane. In this
case, the holder carrying the vane is widened out conically in order to protect the
points of suspension against moisture. The revolving chimney cowl may also be
provided with an Archimedean, spiral or the like screw, without thereby altering
anything in the essence of this invention.
In order to diminish friction between the projecting flange B and the ring or flange C
serving as the guide bed, several balls K, capable of rolling freely, may be inserted
between the same, onto which then the weight of the revolving cowl is transferred.
Such a method of construction is shown in Figure 2, but otherwise the arrange-
ment may be exactly as shown in Figure 1. The ring flange C is bent up to
receive the balls, whilst the projecting flange B is also correspondingly formed to
receive the balls.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is:-
The improvements in or connected with chimney cowls or other similar cowls,
which consist in the employment
1st. Of a spindle O, carrying the cowl H (which is closed at the top) together
with a projecting flange B, and of a guide bed C supporting the latter, which is
carried by a cover D supported by the chimney, all arranged substantially as and
for the purposes hereinbefore described.
2nd. In a chimney or similar cowl, constructed as described in Claim 1, of
rolling ball K between the projecting flange B and the guide bed C, for the
purpose of diminishing as much as possible the resulting friction between the two.
