Improvements in or relating to Chimney Cowls and the like.
I, FREDERICK WARREN, No. 59, Holden Street, Radford, in the City of Notting-
ham, Bricklayers' Labourer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to effect improvements in chimney cowls with
revolving heads, so as to prevent these heads from clogging or becoming fast-as
now often occurs through soot and rust and the like getting in the bearings.
For this purpose-instead of carrying the revolving head on a bearing or centre
on or in the top part of the stationary part of the cowl or chimney, I suspend
the revolving head from a centre, or bearing outside, above, and away from the
stationary part, by means of a spindle fitted with one or more collars attached
to the top of the revolving cowl. This spindle turns in a suitable bearing carried
by one or more supports from the chimney or stationary part of the cowl, in such
a manner that the collar revolves freely on the top of the bearing; between which
and the collar I may in some cases introduce friction rollers or balls so as to
cause the head of the cowl to revolve more freely.
The supports carrying the bearing are arranged so that the revolving cowl
head can turn freely all round inside the same without touching the supports.
Dated this 10th day of September 1898.

Improvements in or relating to Chimney Cowls and the like.
I, FREDERICK WARREN, No. 59, Holden Street, Radford, in the City of Notting-
ham, Bricklayers' Labourer, 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:-
The object of my invention is to effect improvements in chimney cowls with
revolving heads, so as to prevent these heads from clogging or becoming fast-as
now often occurs through soot and rust and the like getting in the bearings.
For this purpose-instead of carrying the revolving head on a bearing or centre
on or in the top part of the stationary part of the cowl or chimney, I suspend
the revolving head from a centre or bearing outside, above, and away from the
stationary part, by means of a spindle fitted with one or more collars attached

by one or more supports from the chimney or stationary part of the cowl, in such
a manner that the collar revolves freely on the top of the bearing; between which
and the collar I may in some cases introduce friction rollers or balls so as to
cause the head of the cowl to revolve more freely.
The supports carrying the bearing are arranged so that the revolving cowl
head can turn freely all round inside the same without touching the supports.
In order that my invention may be fully understood, and more readily carried
out and into effect, I have appended hereunto one sheet of drawings whereon;
Figure 1 represents my improved chimney cowl in elevation, and partly in
section.
Figure 2 represents a side view of the same.
Similar letters of reference refer to similar parts throughout the various
figures.
In these figures A is the stationary part of the cowl or chimney; and B is the
revolving head, which is suspended from the bearing 1) by means of the spindle C
securely attached to the head B, and fitted with a collar Cresting and turning
upon the upper part of the bearing D. This bearing D is supported above and
away from the stationary part D by means of the arms D₁, and the supports E, E,
which are made sufficiently wide so as to allow the revolving part 1 of the cowl
to turn freely all around inside the same, suspended by the spindle C which turns
easily in the bearing D. In some cases I may introduce or fit friction balls
between the collar C, and the upper part of the bearing D; these balls run-
ning in suitable paths formed therein. F is the weather vane attached to the
spindle C.
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—
1st. In chimney cowls with revolving heads, forming them with one or more
outside bearings, attached to the stationary part of the cowl, in combination with
a spindle and collar attached to the revolving head of the cowl by which it is
suspended and turns freely in the aforesaid bearing, as shewn by Figs. 1 and 2
on the drawings herewith for the purposes herein set forth, and substantially as
herein before described.
2nd. In chimney cowls, the combination of a revolving head having a collared
spindle attached thereto outside the same with a bearing attached to the
stationary part of the cowl, and in which the said spindle turns; all for the
purposes herein set forth, and substantially as hereinbefore described and shown
on the drawings herewith.
3rd. In chimney cowls with revolving heads, the combination therewith of
friction balls placed between the spindle collar and the bearing on which the
revolving head turns, all for the purposes hereinbefore described.
4th. The arrangement and combination of parts of chimney cowls as shewn by
Figs. 1 and 2 herewith, all for the purposes named herein, and substantially as
hereinbefore described.
Dated this Tenth day of June 1899.
