Improvements in Windguards for Chimney Tops.
JOSHUA GEORGE MILLS, 7, Acacia Grove, West Kirby, in the County of Chester,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention has for its object certain improvements in windguards for
chimney tops to prevent downward draught and consists of a cylindrical tube
made preferably of metal, the said tube may be made in two sections, the upper
part being somewhat of an inverted cone shape, being made to fit the ordinary
chimney pots when detached from the lower half. On the upper part of the
said tube is placed a flange which surrounds the outer edge, the said flange in-
clining downward has somewhat of a bell shaped mouth which extends outward
from the central tube, the upper half of the tube tapers downwards to enable it
to be fitted to ordinary chimney pots, & may be disconnected from its lower half
for this purpose, otherwise it may be used as a whole, the lower half of the tube
towards its base inclines outward assuming a bell shape at the bottom to enable
it to be fitted into the brickwork a flange is turned up so that it may rest
steadily when in position.

Improvements in Windguards for Chimney Tops.
I, JOSHUA GEORGE MILLS, of 7, Acacia Grove, West Kirby, in the County of
Chester, Plumber, 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:-
My invention has for its object certain improvements for chimney tops and
ventilating purposes and consists of the following arrangement, a cylindrical
tube is placed in the brickwork of a chimney which the smoke passes through,
around the upper edge of the said tube is fixed a flange with its lower edge.
extending outward somewhat of a bell shape, upon the wind striking the said
flange the smoke is carried off more rapidly, thus preventing the smoke from
reentering the tube and causing any downward draught. The tube is intended
to be made in two sections, the upper section tapering downward towards the
centre half. The object being when separated may be placed in the mouth of an
ordinary chimney pot for the same object. The lower half from its centre
tapers outward and at its base has a flange turned outward, and when connected
to the upper half may be embedded in the brickwork, combining the two sections

page_text: into one. It is also intended the same arrangement may be carried out in stone-
ware with this exception, that its entire length shall not be detachable at its
centre half. It is also intended that the same may be applied for ventilating
purposes, where an upward draught is required for carrying off any foul air
from buildings & etc.
In order that my invention may be fully understood I have attached hereunto
one sheet of drawings to which I will refer. In the said drawings A Fig. 1
shews the flange which encircles the outer tube. B the upper section which
divides from the lower at the point C, at the base of the lower half D a flange is
turned outward which causes it to rest steadily and afterwards embedded in the
brickwork. Fig. 3 shews the upper portion detached and inserted in the top
of an ordinary chimney pot E. It is also intended to manufacture the same
in stoneware if preferable also that the centre half shall not be made detachable
but fitted as a whole as shewn, E Fig. 4.
Having now fully described the nature of my said invention and in what
manner I propose to carry it into effect I would have it be understood that I
claim
First. The combination of parts arranged and acting substantially as and for
the purpose set forth and indicated herein before and in and by the accompany-
ing drawings.
Secondly. The placing of a cylindrical tube in a vertical position capped by a
flange placed at a certain angle to induce the wind to strike it with greater force
substantially as set forth and indicated and lastly by providing a means of
preventing downward draught as a cure for smoky chimneys substantially as
set forth and and indicated.
