An Improved Chimney Cowl and Ventilator.
Year: 1899

page_text: GEORGE NEWELL MILWARD, 88, Albert Road, Handsworth, Birmingham,
Traveller, do hereby declare the nature of this invention to be as follows:-
It consists of an ordinary metal tube or shaft having a stay or support at top
with a hole in centre of such stay or support suitable to admit a bolt or pin to be
fixed perpendicularly I add a covering somewhat similar to a frying pan without
a handle either circular or otherwise, having a hole in centre to allow such cover-
ing to pass down the bolt or pin, in an inverted position or bottom upwards on
to stay or support in order to cover tube or shaft in such a manner as to allow
free vent or egress of smoke or air to come up shaft or tube. I further pass
down the pin or bolt a suitable length or metal tubing I then fix several frying
pan shaped coverings of various diameters or sizes the smallest of them being at
top. Such frying pan or otherwise coverings to be placed in their natural posi-
tion with the bottom part downwards or in other words the reverse way to the
cover immediately over the tube or shaft. Between each of such coverings will
be introduced suitable lengths of tube to support those coverings, the whole
being securely fixed by a finial top of any design tapped to suit the bolt or pin.
The general effect will be that of a pagoda" like appearance. The advantage
I claim is the prevention of down-draught in stormy or windy weather, especially
in the position of certain chimneys or shafts the wind whirls into them. The
frying-pan shaped coverings completely obviate and check the possibility of such
down-draught.

An Improved Chimney Cowl and Ventilator.
I, GEORGE NEWELL MILWARD, late of 88. Albert Road, Handsworth. Birming-
ham, but now of 86, Wellington Road, Edgbaston, in the City of Birmingham,
Traveller, 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 improvements in chimney cowls which may also be
used for ventilating purposes, and consists of the construction and arrangement
of parts as hereinafter described and in order to more clearly explain this my
invention, I have appended hereunto an illustrative drawing upon which are
[Price 8d 1.

page_text: figures and numbers of reference, similar numbers referring throughout the
several views to the same thing or part.
Fig. 1, is a general view of this my invention.
Fig. 2, is a sectional view of the invention on line A-B.
Fig. 3, is a sectional plan view on line C-D.
5, is a metal tube or shaft, which may form the chimney proper or form an
extension of the chimney. At the upper end of the tube is the stay or support 6,
which is secured in any convenient manner, such as by bolts 7, such support
having a central hole to receive the pin 8. Upon this pin is mounted the pan
shaped cover 9, having its rim inverted, between which and the upper end of the
tube 5, is sufficient space for the outflow of smoke or air from the said tube.
Above are further carried the pan shaped parts 10, 11, and 12 (or fewer or more may
be used) having the draining holes 13, so that melted snow or rain may drain
through and drip off the part 9. Preferably these upper pans vary in diameter
somewhat as shown. Between such pans are distance pieces 14, which preserve
their respective distances, the whole being firmly secured together by screw nut 15.
It will be readily seen that such a contrivance may serve not only as a chimney
cowl, but also as a ventilating shaft for other purposes.
By these means the wind in passing or striking the pans 9, 10, 11 and 12, is
split up and diverted so as to entirely prevent down draft, but facilitates the
discharge of smoke or air from the shaft 5.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is-
1. The chimney cowl or ventilator comprising a series of pan like plates, with
one or more plates having inverted rims, combined with and carried upon the
shaft 5, substantially as set forth and shown upon the drawings.
