Year: 1852

page_text: LETTERS PATENT to William Pym Flynn, of 18, Rutland Place,
in the County of Cork, for the Invention of "IMPROVEMENTS IN
PADDLE WHEELS."
Sealed the 8th January 1853, and dated the 1st October 1852.
PROVISIONAL SPECIFICATION left by the said William Pym Flynn
at the office of the Commissioners of Patents, with his petition,
on the 1st October 1852.
I, WILLIAM PYM FLYNN, of 18, Rutland Place, in the County of
Cork, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN PADDLE WHEELS" to be at follows:-
This Invention consists of making the float-boards each of two or
more triangles, and fixing such float-boards to a wheel in opposite in-
clined directions, and in such manner that the angles in the succeeding
float boards will be reversed, that is the wide part of one float-board
will be towards one side of the wheel, and the narrowest part of the
next float-board 'will be towards the same side of the wheel. The suc-
ceeding float-boards will extend beyond at one end, and will not extend
so far at the other end, as the next float-board.

filed by the said William Pym Flynn, in the Great Seal Patent
Office, on the 30th March 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM PYM FLYNN, of 18, Rutland Place, in the County of Cork,
send greeting.
WHEREAS, Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October in the year of our
Lord One thousand eight hundred and fifty-two, in the sixteenth year of
Her reign, did, for Herself, Her heirs, and successors, give and grant
unto me, the said William Pym Flynn, Her special licence, that I, the
said William Pym Flynn, my executors, administrators, and assigns, or
such others as I, the said William Pym Flynn, my executors, adminis-
trators, 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 "IMPROVEMENTS IN PADDLE
WHEELS," upon the condition (amongst others) that I, the said William
Pym Flynn, by an instrument in writing under my hand and seal, 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 William Pym Flynn, 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 thereof (that is to say):
This Invention consists of making the float-boards each of two or
more triangles, and fixing such float-boards to a wheel in opposite in-
clined directions, and in such manner that the angles in the succeeding
float-boards will be reversed, that is, the wide part of one float-board
will be towards one side of the wheel, and the narrowest part of the next
float-board will be towards the same side of the wheel. The succeeding

page_text: float-boards will extend beyond at one end, and will not extend so far
at the other end as the next float-board.
And in order that the Invention may be more fully understood, I
shall proceed to describe the means pursued by me.
Each float-board, in place of being a parallelogram,
is composed of two or more angles; thus,-
Outer Edge.
and, in place of being fixed parallel to the shaft or axis, Inner edge of Float.
they cross it at an angle, each succeeding float-board or paddle crossing
the axis or shaft in an opposite direction, and the wider part of one float
comes nearest the vessel, and the narrowest part of the next comes
nearest the vessel. I would remark, that it is not new, when using
float-boards or paddles of the form of a parallelogram, to cross the axis
alternately at an angle. I do not therefore claim the same, and I
would have it understood, that what I claim is the employment of float-
boards or paddles, each composed of two or more angles, and fixed to
alternate angles across the axis or shaft.
In witness whereof, I, the said William Pym Flynn, have hereunto
set my hand and seal, this Twenty-sixth day of March, in the
year of our Lord One thousand eight hundred and fifty-three.
WILLIAM PYM FLYNN. (L.S.)
