IMPROVEMENTS IN THE APPLICA- TION OF A COMBINATION OF STEAM AND AIR AS A MOTIVE POWER TO SHIPS AND VESSELS OF ALL DESCRIPTIONS." PROAL SPATION
Year: 1864

page_text: LETTERS PATENT to Jean Baptiste Andreux, Toy Maker, and Eugène
Coulon, Gentleman, both of 82, Boulevart Sébastopol, Paris, in the
Empire of France, for the Invention of "IMPROVEMENTS IN THE APPLICA-
TION OF A COMBINATION OF STEAM AND AIR AS A MOTIVE POWER TO SHIPS AND
VESSELS OF ALL DESCRIPTIONS."
PROVISIONAL SPECIFICATION left by the said Jean Baptiste Andreux and
Eugène Coulon at the Office of the Commissioners of Patents, with
their Petition, on the 31st August 1864.
We, JEAN BAPTISTE ANDREUX, Toy Maker, and EUGÈNE COULON, Gentleman,
both of 82, Boulevart Sébastopol, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE APPLI-
CATION OF A COMBINATION OF STEAM AND AIR AS A MOTIVE POWER TO SHIPS AND
VESSELS OF ALL DESCRIPTIONS," to be as follows:-
Our Invention consists in the application of a combination of steam and air
as a motive power to ships and vessels of all descriptions.
Our improvements in the combination of steam and air are as follows:--
We make use of a boiler of suitable shape and size, inside which is coiled a
serpentine copper tube or pipe, through which steam is conducted to a second
tube or pipe hereafter described; the steam in passing through this first tube
is superheated by means of boiling water, steam, jets of gas, or other similar

page_text: For the purpose of increasing the force the superheated steam is
made to escape from this first tubo by a small jet into a second tubo whoso
mouth is slightly funnel-shaped and whose diameter is larger than that of the
first tube; it is in passing from the first to the second tube that atmospheric
air is introduced, the superheated steam drawing it into the second tube as it
enters the funnel-shaped mouth; the other end of the second tube opens at
the stern of the vessel. Other tubes may also lead from this second pipe to the
sides of the vessel, the escape being arranged that the steam strikes in a back-
ward direction so as to aid in propelling the ship.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Baptiste Andreux and Eugéne Coulon in the Great Seal
Patent Office on the 27th February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JEAN
BAPTISTE ANDREUX, Toy Maker, and EUGENE COULON, Gentleman, both of
82, Boulevart Sebastopol, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of August, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, tho said Jean Baptisto Andreux and Eugéne Coulon, IIer special
licence that we, the said Jean Baptiste Andreux and Eugéno Coulon, our
executors, administrators, and assigns, or such others as we, the said
Jean Baptiste Andreux and Eugéne Coulon, our executors, administrators,

timo 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 "IMPROVEMENTS IN THE APPLICATION OF A COMBINATION OF
STEAM AND AIR AS A MOTIVE POWER TO SHIPS AND VESSELS OF ALL DESCRIPTIONS,"
upon the condition (amongst others) that we, the said Jean Baptiste Andreux
and Eugeno Coulon, our exccutors or administrators, by an instrument in
writing under our, or their, or one of their hands and scals, 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

page_text: NOW KNOW YE, that we, the said Jean Baptiste Andreux and Eugéne
Coulon, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say :-
Our Invention consists in the application of a combination of steam and air
as a motive power to ships and vessels of all descriptions.
Our improvements in the combination of steam and air are as follows:-
We make use of a boiler of suitable shape and size, inside which is coiled a
serpentine copper tube or pipe, through which steam is conducted to a second
tube or pipe hereafter described; the steam in passing through this first tube
is superheated by means of boiling water, steam, jets of gas, or other similar
means. For the purpose of increasing the force the superheated steam is
made to escapo from this first tube by a small jet into a second tube whoso
mouth is slightly funnel-shaped and whose diameter is larger than that of the
first tube; it is in passing from the first to the second tube that atmospheric
air is introduced, the superheated steam drawing it into the second tube as it
enters the funnel-shaped mouth; the other end of the second tube opens at
the stern of the vessel. Other tubes may also lead from this second pipe to the
sides of the vessel, the escape being arranged that the steam strikes in a back-
ward direction so as to aid in propelling the ship.
Having thus described our Invention and the node of carrying out the
same, we wish it to be clearly understood that we do not confine ourselves to
the precise details as above described, as such may be varied or modified
without departing from the principle.
In witness whereof, we, the said Jean Baptiste Andreux and Eugèno
Coulon, have hereunto set our hands and seals, this Twenty-first day
of February, in the year of our Lord One thousand eight hundred and
sixty five
