AN IMPROVED CHIMNEY POT OR TERMINAL
Year: 1884

page_text: We, STEPHEN BELHAM and JAMES DOLBY BELHAM both of Buckinghain Palace
Road, in the County of Middlesex, do hereby declare the nature of our invention
for "AN IMPROVED CHIMNEY POT OR TERMINAL to be as follows:―
This Invention has for object the prevention of down draught in chimnies, and
consists of a pot or chimney terminal, of nore or less architectural design, applied
at the top of the chimney, moulded of, any suitable material, and composed of a
chamber with curved walls. The said chamber opens below into the chimney and
above into the atmosphere. Over the said chamber is constructed a guard frame
with lateral openings which conduct any lateral draughts of air that may strike
the pot or chimney terminal so that they impinge upon the outsides of the curved
walls of the beforementioned chamber and are thereby deflected upwards so as to
prevent their downward deflection into the chimney. In case, however, any portion
of the draught should be deflected downwards into the chamber, oblique holes are
provided near the lower sides of the walls of the said chamber, through which such
portion of the draught can escape without going down into the chimney.

page_text: We, STEPHEN BELHAM and JAMES DOLBY BELHAM, both of Buckingham Palace
Road in the County of Middlesex, do hereby declare the nature of our invention
for "AN IMPROVED CHIMNEY-POT OR TERMINAL" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying sheet of Drawings
and to the letters and Figures marked thereon, that is to say:-
This invention has for object the prevention of down draught in chimneys, and
consists of a pot or chimney terminal of more or less architectural design, moulded
of any suitable material, and applied at the top of the chimney as shown in the
Drawings hereto annexed in which Figure 1 is an elevation of a single pot or
terminal constructed in accordance with our invention and applied to a single
chimney stack; Figure 2 is a half elevation and half vertical section on line A B
of Figure 4 of a set of three such pots or terminals applied to a compound chimney
stack; Figure is a transverse vertical section on line C D of Figure 1; Figure 4.
is a half plan of Figure 2, and Figure 5 a horizontal sectional plan on line Ĕ F of
Figure 3. The pot or terminal is composed of a chainber A with curved walls.
The said chamber A opens below into the chimney B and above into the atmosphere.
Over the said chamber A, is constructed a guard frame C with lateral openings D,
which conduct any lateral draughts of air that might strike the pot or chimney
terminal so that they impinge upon the outsides of the curved walls E of the before-
mentioned chamber A, and are thereby deflected upwards so as to prevent their
downward deflection into the chimney B. In case however any portion of the
draught should be deflected downwards into the chamber A, oblique holes are
provided near the lower sides of the walls E of the said chamber through which
holes such portion of the draught can escape without going down into the chimney.
In the event of a draught of air striking the top of the guard frame C and
passing downwards through the opening G, it is deflected by the sloping sides
thereof and caused to pass out through the opposite lateral opening D and is thereby
prevented from going down the chimney.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The improved chimney pot or terminal constructed with a chamber A bounded
by curved walls E having oblique holes F formed therein; and with a guard
frame C having lateral openings D and an opening G with sloping sides
at the top, the whole combined, arranged and applied as hereinbefore
described, and illustrated in the Drawings hereto annexed, and for the
purpose specified.
