Year: 1853

page_text: LETTERS PATENT to William Rowett, of Liverpool, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN MAKING PADDLE
WHEELS FOR VESSELS PROPELLED BY MOTIVE POWER, WHICH IS CALLED
THE CYLINDER PADDLE WHEEL."
Sealed the 27th April 1858, and dated the 1st March 1858.
PROVISIONAL SPECIFICATION left by the said William Rowett
at the Office of the Commissioners of Patents, with his Petition,
on the 1st March 1858.
I, WILLIAM ROWETT, of Liverpool, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MAKING PADDLE WHEELS FOR VESSELS PROPELLED BY MOTIVE POWER, WHICH
IS CALLED THE CYLINDER PADDLE WHEEL,'" to be as follows:-
The Invention of Improvements in making paddle wheels for vessels
consists of making the floats of a cylindrical form, either solid or hollow,
or shaped to any polygon form, of any shape that may be described,
either within a circle or an ellipse, and of any dimensions that
may be
required for the use of vessels propelled by any description of motive

page_text: power. This Invention includes also any solid or buoyant float that
may be lined within or without with any air-tight material, such as
gutta percha, oil cloth, or any other article that may be applied to the
float, such as I have described, for making it air and water tight.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Rowett, in the Great Seal Patent Office,
on the 1st September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM ROWETT, of Liverpool, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of March, in the year of our
Lord One thousand eight hundred and fifty-three, in the sixteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Rowett, Her special licence that I, the
said William Rowett, my executors, administrators, and assigns, or
such others as I, the said William Rowett, 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 ex-
pressed, 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 MAKING
PADDLE WHEELS FOR VESSELS PROPELLED BY MOTIVE POWER, WHICH IS
CALLED 'THE CYLINDER PADDLE WHEEL," " upon the condition (amongst
others) that I, the said William Rowett, 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 Rowett, do hereby de-
clare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
The invention of Improvements in making paddle wheels for vessels
consists of making the floats of a cylindrical form, either solid or hollow,
or shaped to any polygon form, of any shape that may be described,
either within a circle or an ellipse, and of any dimentions that may be
required for the use of vessels propelled by any description of motive
power. This Invention includes also any solid or buoyant float that
may be lined within or without with any air-tight material, such as
gutta percha, oil cloth, or any other article that may be applied to the
float, such as I have described, for making it air and water tight; or
the float may be made hollow, built with the wheel, and open at the
extreme top, not actually air and water tight.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a side view in section, and Figure 2, an edge view
of a paddle wheel constructed according to the Invention. a, a, is the
