IMPROVEMENTS IN ADAPTING PROPELLERS BAD
Year: 1863

page_text: LETTERS PATENT to William Louis Winans, of Dover Street, in the
County of Middlesex, Gentleman, and Thomas Winans, of Baltimore, in
the United States of America, but now residing at Dover Street, aforesaid,
Gentleman, for the Invention of "IMPROVEMENTS IN ADAPTING PROPELLERS
BAD DRA
Sealed the 8th December 1863, and dated the 22nd June 1863.
PROVISIONAL SPECIFICATION left by the said William Louis Winans
and Thomas Winans at the Office of the Commissioners of Patents, with
their Petition, on the 22nd June 1863.
We, WILLIAM LOUIS WINANS, of Dover Street, in the County of Middlesex,
Gentleman, and THOMAS WINANS, of Baltimore, in the United States of
America, but now residing at Dover Street, aforesaid, Gentleman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN ADAPTING PRO-
PELLERS FOR PROPELLING OCEAN STEAM VESSELS," to be as follows:-
Our Invention of "Improvements in Adapting Propellers for Propelling
Ocean Steam Vessels" relates to certain improvements upon an Invention for
which Letters Patent were granted 19th June 1858, No. 1888, to Ross
Winans and Thomas Winans. The Invention therein described was a
combination of a vertical transverse trunk within the hull of a vessel of
ordinary form, or such forms slightly modified, with a screw propeller of large
size, or two screw propellers placed side by side, whose blades shall project
beyond the outside of the hull.
Our present Invention consists in the combination for ocean steamers of the

page_text: ordinary type of hull with two vertical transverse trunks, one towards each
end of the vessel, with two screw propellers of such large size placed in them
so that the blades project above the surface of the water when the vessel may
be fully loaded, and also in the combination of two propellers, as above named,
with vessels of the ordinary type in general, but so modified towards the ends
as to conform more nearly in form to the hub of the propellers under and for
a convenient distance above the water line. The machinery for driving the
propellers is to be placed between the wheels, and in some cases would drive
both propellers together upon a shaft common to both, and in other cases
would drive them separately by separate engines.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said William Louis Winans and Thomas Winans in the Great Seal
Patent Office on the 22nd December 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
LOUIS WINANS, of Dover Street, in the County of Middlesex, Gentleman, and
THOMAS WINANS, of Baltimore, in the United States of America, but now
residing at Dover Street aforesaid, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of June, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Louis Winans and Thomas Winans, Her special license that we,
the said William Louis Winans and Thomas Winans, our executors, adminis-
trators, and assigns, or such others as we, the said William Louis Winans
and Thomas Winans, our 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 "IMPROVEMENTS IN
ADAPTING PROPELLERS FOR PROPELLING OCEAN STEAM VESSELS," upon the condition
(amongst others) that we, the said William Louis Winans and Thomas
Winans, by an instrument in writing under our 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 imme-
diately after the date of the said Letters Patent.

page_text: ...NOW KNOW YE, that we, the said William Louis Winans and Thomas
Winans, 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, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that is to
say)
Our Invention of "Improvements in Adapting Propellers for Propelling
Ocean Steam. Vessels" relates to certain improvements upon an Invention for
which Letters Patent, were granted 19th Junė 1858, No. 1888, to Ross and
Thomas Winans. The Invention therein described was a combination of a
vertical transverse trunk within the hull of a vessel of ordinary form, or such
form slightly modified with a screw propeller of large size, or two screw pro-
pellers placed side by side, whose blades project beyond the outside of the hull.
Our present Invention consists in the combination for ocean steamers of the
ordinary type of hull of two vertical transverse trunks, one placed towards
each end of the vessel, with two screw propellers, one placed in each trunk, of
such large size that the blades shall project above the surface of the water
when the vessel is fully loaded.
As a modification of the above arrangement, two propellers may be combined
with vessels, the hulls of which are so modified towards the ends as to conform
more nearly in form to the hub of the propellers under and for a convenient
distance above the water line.
The machinery or engine for driving the
propellers is to be placed between them. In some cases both propellers may
be mounted upon the same shaft, and the engines may be made to actuate
both propellers simultaneously. In other cases the propellers may be mounted
on separate shafts and actuated by separate engines, so that the propellers
may be used singly or may be driven either in the same or in opposite
directions.
In the accompanying Drawing, Fig. 1 is an elevation of so much of the
side of a vessel as is necessary to shew our Invention. A, A, is the hull of
the vessel, in which are made two openings or trunks to receive the propellers
B, B, which are made of large diameter, and are provided with any suitable
number of vanes or blades. The hub of each of the propellers is made of as
large a diameter as possible within the limits of the lines of the vessel so as
to fill up as far as possible that portion of the vertical opening or trunk which
is below the water line. Fig. 2 is a side view of part of a vessel shewing a
modification of the above. In this instance the propellers are placed in the
dead wood at the stern and bows of the vessel instead of in vertical trunks or
openings cut in the hull of the vessel, as in Fig. 1. The bows of the vessel

page_text: below the water line and for a convenient distance above are of such a nature
as to bring the submerged part into the form of a double conical spindle, of
which the hubs of the propellers will form a portion; the lines of the vessel
being continued past the hubs and terminated in conical projecting points C, C,
one of which is fixed to or forms a portion of the dead wood at the stern, and!
the other is fixed to and projects from a false cutwater at the bows.
Having now described our Invention of "Improvements in Adapting
Propellers for Propelling Ocean Steam Vessels," and having explained the
manner of carrying. the same into effect, we claim as the Invention secured
to us by Letters Patent as aforesaid, the application of two large screw
propellers, only. partially immersed, to vessels for ocean navigation, in the
manner and for the purpose herein set forth.
In witness whereof, we, the said William Louis Winans and Thomas
Winans, have hereunto set our hands and seals, this Seventeenth
day of December, in the year of our Lord One thousand eight hundred
and sixty-three..
