page_text: I, JOSEPH BARNET COHEN of St Kilda Street, Middle Brighton in the Colony of
Victoria, Architect do hereby declare the nature of this invention to be as follows
or
This flue cap is capable of being applied to flues of all kinds and sizes for the
purposes of preventing down-draught in flues and increasing the up-draught in same
The apparatus consists essentially of a case constructed of metal, terra-cotta
other suitable material fixed on the outlet of the flue, and opening into the sɩme to
allow the smoke &c to enter the flue cap The sides ends and top of the case are
furnished with openings partially closed by fixed or movable louvres, these louvres
are so disposed as to deflect the air striking against them always in an upward
direction This prevents the possibility of down draught The louvres to the sides
ends and top of the case are so disposed as to deflect the air striking against them in
different planes both in a horizontal and vertical sense and the diverging currents of
air thus formed produce or have a tendency to produce partial vacuums in the spices
between them outside the case and into these spaces the smoke &c from the interior of
the flue is forced by the greater general pressure of the atmosphere This increases
the up-draught

page_text: I, JOSEPH BARNET COHEN, of St Kilda Street, Middle Brighton in the Colony of
Victoria, Architect, 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 flue cap is capable of being applied to flues of all kinds and sizes for the
purposes of preventing down-draught in flues and increasing the up-draught in same,
as I will describe referring to the accompanying drawing
The apparatus consists essentially as illustrated in the accompanying drawing of
case A of metal, terra-cotta, or other suitable material adapted to be fixed on the
outlet of the flue, and opening into the same to allow the smoke &c to enter the flue
cap The sides and top of the case A are furnished with openings BC each partially
closed by a fixed or movable louvre DE, these louvres are so disposed as to deflect
the ur striking against them always in an upward direction This prevents the
possibility of down draught The said louvres are disposed as clearly illustrated in the
drawing so as to deflect the air striking against them in different planes both in a
horizontal and vertical sense and the diverging curronts of ur thus formed produce or
have tendency to produce partial vacuums in the spaces between them outside the
case and into these spaces the smoke &c from the interior of the flue is forced by
the greater general pressure of the atmosphere This increases the up-draught
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 18 -
A flue cap having openings in its sides and top partially closed by louvres such
as DE so disposed as to deflect the air in different planes substantially as and for the
purpose specified and as illustrated in the accompanying drawing
