Year: 1863

page_text: LETTERS PATENT to Henri Adrien Bonneville, Patent Agent, of the
British and Foreign Patent Offices, 24, Rue du Mont Thabor, Paris, in the
Empire of France, for the Invention of "AN IMPROVED COWL OR CHIMNEY
PoT." A communication from Yves Marie Pouliquen, residing at Brest,
in the Empire of France aforesaid.
PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition, on
the 10th November 1863.
I, HENRI ADRIEN BONNEVILLE, Patent Agent, of the British and Foreign
Patent Offices, 24, Rue du Mont Thabor, Paris, in the Empire of France, do
hereby declare the nature of the said Invention for "AN IMPROVED COWL OR
CHIMNEY POT," communicated to me by Yves Marie Pouliquen, a person
residing at Brest, in the Empire of France, aforesaid, to be as follows, that
is to say:-
1
The object of this Invention is the prevention of smokey chimnies by
ensuring the escape of the smoke in whatever direction the wind may blow.
The annexed Drawings represent, Fig. 1, a plan view from below; and
Fig. 2, an elevation of the apparatus. In both Figures corresponding parts
are represented by similar letters of reference.
A is a tube forming the body of the apparatus; B, cap, by means of which
the tube A is closed, being removed only for cleaning; D, E, F, G, are four
smaller tubes, fixed to and communicating with the tube A, by which the

page_text: smoke escapes. These tubes are bent downwards, the openings by which the
smoke is emitted being indicated in the annexed Drawings by D', E', F¹, G¹.
Between these tubes are placed four isolated partition boards H, I, J, K,
which prevent the wind from acting laterally on their openings.
By this arrangement the smoke flows freely in whatever way the chimney 5
may be dominated, and whatever may be direction and strength of the wind.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henri Adrien Bonneville in the Great Seal Patent Office
on the 9th May 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, Patent Agent, of the British and Foreign Patent Offices,
24, Rue du Mont Thabor, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of November, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
the said
me, the said Henri Adrien Bonneville, Her special licence that
Henri Adrien Bonneville, my executors, administrators, and assigns, or such
others as I, the said Henri Adrien Bonneville, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED COWL OR CHIMNEY POT," a communication from
Yves Marie Pouliquen, a person residing at Brest, in the Empire of France,
aforesaid, upon the condition (amongst others) that I, the said Henri Adrien
Bonneville, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-

page_text: The object of my Invention is to prevent smokey chimnies by securing a
regular and easy flow of smoke in whatever way the chimney top may be
dominated or shut in, and whatever may be the direction of the wind. For
this purpose the apparatus herein-after described has been devised, and is
represented in the annexed Drawings, Fig. I. of which is a transverse section,
Fig. II., a perpendicular elevation, and Fig. III., a plan view from below. In
these three Figures the same letters of reference indicate similar parts.
A is a tube of sheet iron, zinc, or other suitable material, closed at top by a
cap B, hinged or otherwise, which may be opened for cleaning, but which is
usually shut, and held in place by a spring catch C, actuated from without
by a button or other similar contrivance. At a suitable distance below this
cap there are fixed and firmly soldered four tubes or hollow wings D, E, F, G,
curved downwards, communicating with the tube A by the openings marked
a, b, c, and with the exterior by the openings d, e, f, Fig. 1. Between these
tubes or curved passages are placed four partition boards H, I, J, K, formed
of sheet iron, zinc, or other suitable substance, and fixed edgeways on the
tube A, which protect the openings of the wings or side tubes D, E, F, G,
from the lateral influence of the wind, the peculiar form of the latter pre-
venting any direct action on these openings. L, M, N, are three rings by
which wires or cords may be passed for steadying the apparatus when placed
in isolated or exposed situations.
Having now described the nature of the said Invention, and the manner
in which the same is to be performed, I do not claim the tube A, cap B,
rings L, M, N, or other parts of the apparatus abstractedly; but what I do
claim, and desire to secure by Letters Patent, is, the combination of the cap B,
the tubes D, E, F, G, and partitions H, I, J, K, substantially as and for the
purpose above set forth and represented in the annexed Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Seventh day of May, in the year of our
Lord One thousand eight hundred and sixty-four.
