IMPROVEMENTS IN CHIMNEY POTS
Year: 1887

Specification Accepted, 5th Apr., 1887.
I JAMES TAYLOR of 99 Candahar Road Battersea in the county of Surrey Builder's
Foreman do hereby declare the nature of my invention for IMPROVEMENTS IN CHIMNEY
POTS and in what manner the samo is to be performed, to be particularly described
and ascertained in and by the following statement :-
:-
The object of my invention is to provide on chimneys of ordinary construction
a metallic or earthenware chimney pot of special design intended to obviate
blow-down, or the wind beating down the flue proper. In my improved appliance
I provide a metal terminal (with arms) closed at the main orifice with a
wedge-shaped cap or covering and with arms and orifices as figured in the
drawings annexed. This terminal with its cap and arms may be made of any
metal or of earthenware and in one or two or more parts as may be found convenient.
I prefer however to use zinc and will proceed to describe my invention as made in this
metal.-The base of the terminal is made square, or rectangular passing to a cylindrical
form in the chimney pot proper. From this chimney pot arms with open extensions
are affixed on either or both sides and the top of the main pot is closed with a wedge-
shaped cap or cover before mentioned. In order that my invention may be better
understood I append drawings in which figure 1 is a perspective view and figure 2
a section of my improved chimney pot. Similar letters referring to similar parts
in each figure-A is the loose or removable wedge-shaped cap or cover B. B. the
arms branching off from. the main stem or the chimney pot proper C. C. denote
the orifices at the top of the extensions before mentioned, D. D. the orifices at the
bottom of the same extensions. E. E. are wind guards placed in the extensions for
the purpose of directing the current of air when a downward wind is blowing; or
occurring; away from the arms leading to the flue or chimney proper. F. is the
main stem or chimney pot proper.
Wind or what is technically known as down-blow is prevented from entering
the main stem or flue proper by means of the cap A which entirely cuts off the flue
proper from direct influence or contact with the atmosphere above; thus preventing
any downward current. If a downward beating wind exists, the action of my
improved chimney will prevent down-blow in the following manner :-The wind
would enter extensions or side pots C. D. C. D. at the top C. C. passing out at the
bottom D. D. and being deflected away from the arms or junctions to flue proper by

page_text: wind-guards E. E. placed in the side pots or extensions for that purpose. These guards
are placed immediately above the orifice where the side arms enter the side pots and
their purpose is to direct the current of air out at the bottom of the side pots D. D.
It will be noticed that these guards while effectually preventing wind from entering
the arms or junctions to the flue do not interfere with the free egress of the smoke.
The cap or cover A lifts out easily from the pot and the base or bottom being made
wedge-shaped it dips into the main stem F. cutting as it were the volume of ascending
smoke and deflecting the same into the side arms B. B. from whence it will find a free
exit at the orifices C. C. or in the case of a strong down-beating wind at the lower
orifices of the side pots D. D.
Although I prefer to make my improved chimney pot of the form and section shown
in the drawings it will be understood that varieties of design and material separately
or in combination may be made as required.
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
I. A main chimney pot with arms partially or wholly horizontal and vertical or
horizontal extensions.
II. A cap with wedge-shaped base covering main-flue loose or fitted.
III. Wind-guards fixed in the extension or side pots.
IV. A chimney pot constructed with main stem, cap or cover, wedge-shaped arms
or junctions from same to extensions or side pots, the side pots fitted with wind guards
as herein before described and illustrated substantially as set forth.
