I JOSEPH WINTERFLOOD of 346 Euston Road London in the County of Middlesex
Metal Worker do hereby declare the nature of this invention to be as follows :-
The object of this invention is to construct a chimney or ventilating cowl, that by
its revolving action will produce an up current, and at the same time prevent rain
beating down which is a frequent cause of down draughts-I construct a top and
bottom rim of a suitable diameter, and connect thereto a number of vanes or fans of a
treble curved form. To the top rim I connect a conical shaped cover smaller in
diameter than the top rim, and to this cover I connect a number of single curved fans
or vanes: To carry this chimney or ventilating cowl I connect a square bracket
or cross bar, to a pipe or tube, and on this bracket or cross bar 1 connect an iron
socket with a steel bearing in its bottom end-the spindle being fixed point down-
wards in the conical shaped cover :-To oil the spindle and bearing I carry a tube
from the top of the conical shaped cover down in a line with the spindle, till it reaches
the iron socket above mentioned.

I JOSEPH WINTERFLOOD, of 346, Euston Road, London, in the County of Middlesex,
Metal Worker, 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 this invention is to construct a chimney or ventilating cowl that by
its revolving action will produce an up current, and at the same time prevent rain
beating down which is a frequent cause of down draughts -I construct a top and
bottom rim of a suitable diameter and connect thereto a number of vanes or fans, of a
treble curved form, to the top rim I connect a conical shaped cover smaller in diameter
than the top rim and to this cover I connect a number of single curved fans or vanes:-
To carry this chimney or ventilating cowl, I connect a square bracket or cross bar to
a pipe or tube, and, on this bracket or cross bar I connect an iron socket with a steel
"bearing in its bottom end, the spindle being fixed point downwards in the conical
shaped cover.
To oil the spindle and bearing I carry a tube from the top of the conical shaped
cover down in a line with the spindle till it reaches the iron socket above mentioned.
In order that my invention may be more fully understood and carried into practical
effect I will refer to the drawings hereunto appended
Figure 1. is an elevation of the chimney or ventilating cowl. Figure 2. is a plan
of the same and Figure 3. is a vertical section; A. is the fans or vanes attached to
the top and bottom rims B. C. is the tube or pipe, and D. is the cross bar and socket
wherein the spindle works. E. is the spindle, and F. is the small tube for oiling the
spindle and bearing; G. is a small tube fixed to the oil box and carried outside the
pipe or tube, to enable the operator to tell when, the oil box is full. H. is a screw
connection where the oil is poured in.
+
I have shown in the annexed drawing a plain form of my improved chimney or
ventilating cowl, but it is obvious that I do not limit myself to the form or shape of
the said cowl, or to the method and details of constructing and fitting the same; for
each chimney or ventilating cowl can be so ornamented or otherwise treated, in such
a manner as may be convenient in each particular case.
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 :-
-
First In a revolving chimney or ventilating cowl the treble curved fans or
vanes A. verticaly arranged substantially as and for the
described
purpose hereinbefore

page_text: Second-The method or manner of fixing the small tube F. for the purpose of
oiling the spindle and bearing substantially as and for the purposes herein set forth
and illustrated.
Third In revolving chimney or ventilating cowl the combination of the treble
curved fans or vanes A. with the small tube F. the top and bottom rim B. the cross
bar and socket D. the spindle E. the overflow pipe G. and the whole combined and
operating substantially as hereinbefore described and illustrated.
Fourth: The revolving chimney or ventilating cowl substantially as herein before
described and set forth in the annexed drawing.
