page_text: LETTERS PATENT to Pierre Marie Fouque, Civil Engineer, Louis
Réné Hébert, and Vincent Etienne Doret le Marneur, of Paris,
in the Empire of France, and of 16, Castle Street, Holborn (City).
London, for the Invention of "A FORTUNE RUDDER IN BRONZE."
ed the Sth March 1854, and dated the 21st October 1853.
PROVISIONAL SPECIFICATION left by the said Pierre Maric
Fouque, Louis Réné Hébert, and Vincent Etienne Doret le
Marneur at the Office of the Commissioners of Patents, with
their Petition, on the 21st October 1858.
We, PIERRE MARIE FOUQUE, Civil Engineer, Louis RENÉ HÉBERT,
and VINCENT ETIENNE DORET LE MARNEUR, of Paris, in the Empire of
France, and of 16, Castle Street, Holborn (City), London, do hereby
declare the nature of the said Invention for "A FORTUNE RUDDER
IN BRONZE" to be as follows:-
Fig. 1, represents the Invention as applied to a ship. Fig. 2, is au
end view of the back of the rudder. Fig. 3, is horizontal plan of
one of the connecting irons of the stern post. Fig. 4, is a vertical
projection of the bar of the rudder.
By the Drawing it will be seen that the common woodden rudder a,

page_text: is of the ordinary construction, and is provided with a head b, and a
bar c, and is carried by pintles d. The rings e, receive the pintels d, of
this rudder, and are united by the same iron work as those f, which
receive the pintles g, of the rudder h, which in its normal state is placed
against the stern post or the keel of the ship, and is kept there by a
holti, of which the lower end enters a staple j, & by fixing the bar c,
on the head k, of the rudder h, and receives the end of the bolt i, the
upper part of which rises above the head of the rudder. The parts
thus arranged, if the ordinary rudder be carried away, raise the end of
the bolt i, which slides in the guides, in order to disengage its lower
part from the staple 7, and fix the bar c, on the head k, of the rudder h,
a new rudder is instantly made. This new rudder is made of bronze to
prevent corrosion, and can be made thinner with equal strength.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Pierre Marie Fouque, Louis Réné Hébert, and
Vincent Etienne Doret le Marneur in the Great Seal Patent
Office on the 21st April 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we,
PIERRE MARIE FOUQUE, Civil Engineer, LOUIS RENÉ HÉBERT, and
VINCENT ETIENNE DORET LE MARNEUR, of Paris, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of October, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Pierre Marie Fouque, Louis Réné
Hébert, and Vincent Etienne Doret le Marneur, Her special licence
that we, the said Pierre Marie Fouque, Louis Réné Hébert, and
Vincent Etienne Doret le Marneur, our executors, administrators, and
assigns, or such others as we, the said Pierre Marie Fouque, Louis
Réné Hébert, and Vincent Etienne Doret le Marneur, 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

page_text: 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 "A FORTUNE
RUDDER IN BRONZE," upon the condition (amongst others) that we, the
said Pierre Marie Fouque, Louis Réné Hébert, and Vincent Etienne
Doret le Marneur, or some or one of us, by an instrument in writing
under our hands and seals, or under the hands and seals of some or one
of us, 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 we, the said Pierre Marie Fouque, Louis
Réné Hébert, and Vincent Etienne Doret le Marneur, do liereby
declare the nature of our said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement:
Our Invention provides a prompt and casy meaus for ships and
vessels of any kind, whenever they may have lost or damaged their
ordinary rudder to substitute immediately another rudder in the stead
of that lost or damaged, capable of performing the same duties, and
enabling the vessel to be steered with the same facility as before. In
order that the nature of our Invention, and the mode in which the same
is to be carried out, may be more clearly understood, we refer to the
annexed Drawings as follows:-Fig. 1, shews a side view of the stern
of a vessel to which our said Invention has been applied. Figures
2, 3, 4, 5, and 6, represent letached parts of the Invention. In these
various Figures the corresponding parts are indicated by the same
letters of reference. Fig. 1, A represents the ordinary wooden rudder
in the way the same is usually fixed to the stern posts of vessels,
and its different parts, of which we have not to explain the effects,
marked on the plan C, E, G, and in Fig. 2, H. and P. Fig. 1, B
represents the fortune rudder; D, the rudder head of the same rudder;
F, the pintles. Fig. 2, I the lateral aperture at the angle of rudder
bands or straps on the stern post.
Fig. 1, La bolt for the. purpose of

page_text: keeping the fortune rudder against the dead wood. Fig. 3, M. cap
and screw bolt to hold the tiller in its position when in use. N, Fig. 3,
bonnet on rudder head, receiving the tiller into a socket when in use.
Fig. 4, O the eye bolt screwed into the dead wood for holding the
lower extremity of the bolt I, when the rudder is not in use. Fig. 2,
P the rudder band, with the two openings for the pintles. Figures 1,
and 6, Q guide for the retaining bolt of the fortune rudder. Fig. 5,
R collar of the tiller of the fortune rudder, fitted with six pullies for
the tiller ropes, marked S, Fig. 5. Fig. 1, Twooden sheathing; of suf-
ficient thickness to lic flush with the fortune rudder when not in use,
so as to prevent the resistance of the water on the edge of the rudder
when the vessel is in motion, and sweetening away to nothing at a
short distance from that edge. The fortune rudder B, when not in use,
is laid against the dead wood at the lower part of the ship's run, and it
is hung by its pintles in the lateral aperture in the rudder bands of the
ordinary rudder A; but we reserve to ourselves the right of making the
lateral aperture I, and the pintles F, distinct from the rudder A, then
by the bolt L, the under part is held in the eye bolt O. This eye bolt
passes through an opening in the lower part of the fortune rudder B,
and projects sufficiently to allow the bolt L, to pass through the eye of
the eye bolt O, so that the fortune rudder being placed against the
dead wood of the vessel it is firmly secured in a proper position, and
the upper extremity of the bolt L passes through the deck close to the
rudder head D. The way in which the fortune rudder will act is as
follows: If by any accident the common rudder should be carried
away, unshipped, destroyed, or damaged and removed, the bolt L is
raised or unshipped from the eye bolt O, and the fortune rudder is set
at liberty and at onco brought into action. The tiller is then fixed to
the rudder head D, by lifting the cap M, inserting the tiller, bringing
down the cap, and securing all by the screw bolt through the centre of
the cap M, and the bonnet N; the collar Ris then applied to the end
of the tiller and the tackle rove through the sheaves, and the fortune
rudder will then be as easily use and efficacious as an ordinary rudder.
We construct our rudders in bronze, as being less liable to corrode,
and occupying less space.

page_text: Having thus described the nature of our Invention, and the manner
of using it, we declare that what we claim as our Invention and wish
to secure is, an entirely novel application of a rudder in bronze mung
at the stern post of vessels or ships so as to be secured flat against the
dead wood whilst not in use in the way that we have already explained,
and so that it may be instantly brought into use whenever the ordinary
rudder may be destroyed, or injured and removed, by means of a bolt
reaching to the deck of the vessel, as already described, or in any other
way of fixing the same in the position already described. We especially
reserve the right of placing the fortune rudder in ships and vessels in
any convenient part of the stern, keeping always to the principle of our
Invention, which is, a rudder to be disengaged and brought into use
only when required, and not dininishing the speed of the vessel, and
instantly replacing the ordinary rudder when carried away or disabled
and removed.
In witness whereof, we, the said Pierre Marie Fouque, Louis
Réné Hébert, and Vincent Etienne Doret le Marneur, have
hereunto set our hands and seals, this Thirteenth day of April,
in the year of our Lord One thousand eight hundred and
fifty-four.
