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 afore-
said, Gentleman, for the Invention of "IMPROVEMENTS IN ADAPTING SCREW
PROPELLERS FOR PROPELLING SHIPS OR VESSELS FOR OCEAN NAVIGATION.”
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 8th December 1863.
We, WILLIAM LOUIS WINANS, of Dover Street, in the County of Middlesex,
Gentleman, and THOMAS W-INANS, 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
SCREW PROPELLERS FOR PROPELLING SHIPS OR VESSELS FOR OCEAN NAVIGATION,"
to be as follows:-
Our present Invention of "Improvements in Adapting Screw Propellers for
Propelling Ships or Vessels for Ocean Navigation," relates to the adaptation
of two, three, or four propellers to and combination with a spindle-shaped
hull, such as was invented by Ross and Thomas Winans, and for which
Letters Patent were granted to them 19th June 1858, No. 1886.
The Invention consists, first, of a combination of two screw propellers,
which may be wholly or partially submerged, one of which is placed at each

page_text: end of the vessel. The propellers may be placed on the same shaft or on
separate shafts, as may be deemed most desirable.
The Invention consists, secondly, of a combination of three screw pro-
pellers, which may be wholly or partially submerged, two of which are placed
at one end of the vessel and one at the other end. These propellers are each
placed on separate shafts.
The Invention consists, thirdly, of a combination of four propellers, which
may be wholly or partially submerged, two of which are placed at each end
of the vessel. The four propellers may be placed upon two shafts, or each
may be placed upon a separate shaft.
The Invention consists, fourthly, in the adaptation to one end of a spindle-
shaped vessel of two screw propellers on separate shafts and on opposite sides
of the vessel.
The propeller shaft or shafts may be placed in any suitable position in the
vessel, at or below the centre line or line of flotation, and may be actuated by
the same or by separate engines, and the propellers may be driven in the same
or in opposite directions.
The Invention likewise consists in similar adaptations and combinations of
propellers to or with a spindle-shaped hull, having a flat or nearly flat upper
deck, with bulwarks, railing, or cabin or cabins, with upper or hurricane
deck, similar to that invented by us, and for which we have applied for Letters
Patent.
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 8th June 1864,
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 Eighth day of December, 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 Winan, our
executors, administrators, and assigns, or such others as we, the said William

page_text: 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 SCREW PROPELLERS FOR PROPELLING SHIPS OR
VESSELS FOR OCEAN NAVIGATION," upon the condition (amongst others) that
we, the said William Louis Winans and Thomas Winans, by an instru-
ment 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 immediately after the
date of the said Letters Patent.
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 present Invention of "Improvements in Adapting Screw Propellers for
Propelling Ships or other Vessels for Ocean Navigation," relates to the
adaptation of two, three, or four propellers to and in combination with a
spindle-shaped hull, such as was invented by Ross and Thomas Winans, and
for which Letters Patent were granted to them 19th June 1858, No. 1386.
The Invention consists, first, of a combination of two screw propellers,
which may be wholly or partially submerged, one of which is placed at or
near each end of the vessel. The propellers may be placed on the same shaft
or on separate shafts, as may be deemed most desirable.
The Invention consists, secondly, of a combination of three screw propellers,
which may be wholly or partially submerged, two of which are placed at or
near one end of the vessel and one at or near the other end. These pro-
pellers are each placed on separate shafts.
The Invention consists, thirdly, of a combination of four propellers, which
may be wholly or partially submerged, two of which are placed at or near
each end of the vessel. The four propellers may be placed upon two shafts,
or each may be placed upon a separate shaft.
The Invention consists, fourthly, in the adaptation at or near one end of a
spindle-shaped vessel of two screw pr.pellers, with a rudder between them.
The propeller shaft or shafts may be placed in any suitable position in the

page_text: vessel, at or below the centre line or line of flotation, and may be actuated by
the same or by separate engines, and the propellers may be driven in the same
or in opposite directions.
The Invention likewise consists in similar adaptations and combinations
of propellers to or with a spindle-shaped hull, having a flat or nearly flat
upper deck, with bulwarks, railing, or cabin or cabins, with upper or hurricane
deck, similar to that invented by us, and for which Letters Patent were
granted to us on the Twentieth of June, One thousand eight hundred and
sixty-three, No. 1555.
In the accompanying Drawing, Fig. 1 is a side elevation of part of a
spindle-shaped vessel, with a screw propeller a adapted near to one end;
Fig: 2 is a front view of the same. The propeller may be of the ordinary
construction, and is mounted on one end of the shaft b, which may, if desired,
be provided at the other end with a similar propeller. The projecting end of
the shaft 6 is supported in bearings in the brackets c, c, which are secured to
the pointed end of the vessel. The rudder d, d, is placed in front of the pro-
peller, and is made double, that is, there are two plates, one on each side of
the propeller shaft. Fig. 3 is a side elevation of part of a spindle-shaped
vessel, to which two propellers are adapted at the same end of the vessel;.
Fig. 4 is a front view of this part. It will, of course, be obvious than in
combination with these two propellers, one or two propellers may be adapted
to the opposite end of the vessel, so that the vessel may have two, three, or
four propellers. When there are two propellers at the same end of the vessel,
the rudder, which is placed in advance, is situated between the two propelling
shafts, which are supported by bracket arms, as in the former instance.
Having now described our Invention of "Improvements in Adapting
Screw Propellers for Propelling Ships or Vessels for Ocean Navigation," and
having explained a manner of carrying the same into effect, we claim as our
Invention,―
First, the adaptation to spindle-shaped vessels of two screw propellers,
wholly or partly submerged, one of which propellers is placed at or near
each end of the vessel, as herein set forth.
Second, the adaptation to spindle-shaped vessels of three screw propellers,
wholly or partly submerged, two of which are placed at or near one end and
one at or near the other, as herein set forth.
Third, the adaptation to spindle-shaped vessels of four screw propellers,
wholly or partly submerged, two of which propellers are placed at or near
each end of the vessel, as herein set forth.
Fourth, the adaptation to one end of a spindle-shaped vessel of two screw

page_text: propellers, wholly or partly submerged, and combined with a central rudder,
in the manner herein set forth.
Lastly, we claim the adaptation of any of these arrangements of screw pro-
pellers to spindle-shaped vessels, with flat or nearly flat upper decks.
In witness whereof, we, the said William Louis Winans and Thomas
Winans, have hereunto set our hands and seals, this Second day of
June, in the year of our Lord One thousand eight hundred and sixty-
four
