PROVISIONAL SPECIFICATION.
An Improved Chimney Pot:
I, ALBERT GIESAU of Kaiserstrasse, Magdeburg in the German Empire,
Manufacturer, do hereby declare the nature of this invention' to be as follows:-
The chimney pot of this invention has a vertical pipe the bottom part of which
is entered in or seated upon the top of the chimney. The upper part of the
vertical pipe communicates with a globular enlargement into the bottom of which
and from the top of which lead pipes fixed to the globe obliquely so that a number
of cross passages are formed into and through the globe. The oblique passages
have for object to cause a draught in the chimney and dilute the smoke with air.
In the case of a side wind the smoke is discharged from the oblique pipes located
on the opposite upper surface of the globe. With the wind from above the smoke
is driven out from the bottom oblique passages. Each upper oblique pipe is in a
line with a bottom one.

COMPLETE SPECIFICATION.
An Improved Chimney Pot.
I, ALBERT GIESAU of Kaiserstrasse, Magdeburg, in the German Empire,
Manufacturer, 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 provide a chimney pot or chimney top
mounting for improving the draught of the chimney and preventing back passage
of smoke in all conditions of weather.
In the drawing Figs. 1 and 2 are respectively a vertical section and a plan of
the device of this invention.
A is a pipe the bottom part of which is entered in or seated upon the top of the
chimney or upon an upward extension of the same. The upper part of the pipe A
communicates with a hollow globular enlargement B into the bottom and from the top
of which lead short pipes a, b, cast in one piece with, or fixed to the globe B obliquely.
These pipes ab are so arranged upon the globe that each upper one a is in a line
with a lower one b, by which a number of oblique cross passages are formed through
be
the globe. In the drawing four of such passages are shewn but the number may
varied. The outside air passes continuously upwards through said passages whereby
the smoke from the chimney after being diluted in the globe, is driven out at top.
In this way the draught of the chimney is very much improved. In whatever
direction the wind may blow the smoke will always be driven out from the oblique
passages on the opposite upper surface of the globe, any back passage of the same
into the chimney being prevented by the upward air current through the four
bottom pipes. Owing to the pipes being obliquely placed the outlet of the smoke
is to a certain extent covered or shielded by the higher portion of the rims of the
pipes. With the wind from above the smoke is driven out through the bottom
oblique passages without any passing back into the chimney.

page_text: The chimney pot or top may be very easily cleaned from the oblique passages
and from a suitable sliding door in the chimney.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is :-
A chimney pot or chimney top mounting, consisting of a pipe A having at its
upper end a globular enlargement B from which project both above and below a
number of pipes arranged obliquely and so as to form passages or flues crossing
each other in straight oblique lines, for the purpose specified substantially as
described and shewn.
Dated this 10th day of September 1894.
