page_text: LETTERS PATENT to Henry Wyatt, of 58, Pall Mall, London, in the
County of Middlesex, for the Invention of "A PECULIAR APPARATUS FOR
MORE RAPIDLY AND PERFECTLY MANEUVRING OR STEERING STEAM SHIPS OP
PROVISIONAL SPECIFICATION left by the said Henry Wyatt at the Office
of the Commissioners of Patents, with his Petition, on the 27th October
1855.
.J, HENRY WYATT, of 58, Pall Mall, London, do hereby declare the nature
of the said Invention for "A PECULIAR APPARATUS FOR MORE RAPIDLY AND
PERFECTLY MANŒUVRING OR STEERING STEAM SHIPS OF WAR OR OF COMMERCE, AND
WHICH IS ENTITLED THE TRANSPULSOR," to be as follows:-
That by application of a double axis joint in the screw propeller shaft at its
point of exit from the ship's stern post, the said shaft [that portion with screw
propeller, attached] acting upon the above-named axis joint as a centre, can be
turned either to the right or left of the ship's stern, thereby enabling the pro-
peller to drive the ship in any direction with greater facility and rapidity than
by any plan at present employed: The ship can be turned in less space by this
plan. The rotation of the screw propeller is not interrupted in any degree
during its transit from left to right of the ship's stern.. The propeller, when

page_text: not required to act as or in aid of the rudder; can be placed in a central
position with stern of the ship, and with shaft all in line can act as the present
screw propellers to drive the ship ahead only. The propeller can be raised
into the body of the ship, if required;, by a detachment in the shaft joint.
The propeller is moved much upon the principle as a rudder is moved.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Wyatt in the Great Seal Patent Office on the
26th April 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
WYATT, of 58, Pall Mall, London, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of October, in the year of our
Lord One thousand. eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her. heirs and successors, give and grant unto me,
the said Henry Wyatt, Her special licence that I, the said Henry Wyatt,
my executors, administrators, and assigns, or such others as I, the said Henry
Wyatt, 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 "A PECULIAR APPARATUS
FOR MORE RAPIDLY AND PERFECTLY MANEUVRING OR STEERING STEAM SHIPS OF
WAR OR OF COMMERCE, AND IS ENTITLED THE TRANSPULSOB," upon the condition
(amongst others) that I, the said Henry Wyatt, my executors or adminis-
trators, 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 Henry Wyatt, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-.
That by application of a double axis joint (as in the Drawing No. 5 or
No. 6, or any similar joint) in the screw propeller shaft at its point of exit

page_text: from the ship's, stern post, the said shaft, that portion with the screw propeller
attached, acting upon the above-named axis joint as a centre, can be turned
either to the left or right of the ship's stern (see Drawing No. 3), thereby
enabling the propeller to drive the ship in any direction with greater facility
and rapidity (that is, as regards its steering,) than by any plan at present
employed. The ship can be turned in less space as the propeller can be
brought to bear direct upon either side of the stern; the rotation of the
propeller is not interrupted in any degree during its transit from left to right
of the ship's stern, as the double axis joint equalises every deviation of position.
The propeller, when not required to act as a rudder, or in aid of the same, can
be placed in a central position with the stern of the ship, and with the shaft
in continuous line can then act as the present screw propeller to drive her
straight ahead. The propeller can be raised into the body of the ship, if
required, by a simple detachment in the shaft joint. The propeller according
to this Invention is moved upon the same principal as a rudder, and will
yield to the blow of a heavy sea.
This Invention is particularly applicable to vessels navigating intricate and
crowded rivers, and would be of great advantage in case of a vessel running
aground.
The Patentee claims by this Invention, the moving of the screw propeller
upon the principal of a rudder, as before described; and, further, the appli-
cation of a double axis joint for the purpose of rotating the same.
In witness, whereof, I, the said Henry Wyatt, have hereunto set my hand
and seal, this Twenty-sixth day of April, in the year of our Lord
One thousand eight hundred and fifty-six.
HENRY WYATT. (L.S.)
