Year: 1884

page_text: I WILLIAM HEWSON, Keel owner and forwarding agent, 15 lister street Hull do
hereby declare the nature of my invention for IMPROVED STEERING POWER IN
NAVIGATEING SCREW STEAMERS MORE ESSPECALLY IN RIVERS & CANALS ALSO
PREVENTING LOSS OCASIONED BY ORDERNARY RUDDER BREAKING DOWN OR BEING,
TOTALY LOST to be as follows:-
A stern-frame made to acomadato to Rudders, one fixed in frunt of the propeller
& the other aft of the same (space to bo left for the propeller between the two
Rudders the Rudders to work independently of one another, the fore Rudder to be
in two pieces connected by a spectacle to allow of the same heing worked clear of
the shaft) in the same maner as used at prensent by steamers haveing there
propellers fixed out side tho Rudder the after rudder working in the orderay way
the two rudders can when Dessesary bo worked together by conecting same on
deck by chains &c to the steering apparatus in use.
Dated this tenth day of June 1884.

page_text: WILLIAM HEWSON Keel Owner &c 15 Lister Street Hull I do hereby declare the
nature of my invention for SAFETY OF LIFE AND PROPERTY AT SEA and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The Rudders are placed one in front of Propeller and the other behind. These
Rudders are separate and distinct from each other, and can be worked separatly
or jointly as the case requiros by connecting the chains on Deck to be worked by
the ono Whcel. The Double Ruddered Stern framo has many advantages, it is
supposed to give Ship or Steamer fully as much more steering power as they have
at present, more especially a Screw Steamer as the fore Rudder is always in solid
water and the after one in the back water of the Propellor and will prove itself
advantagous in Navigating Suez Canal and other Canals & Rivers of a similar
nature and will prove a great Boon to all Vessels in Ballast, as the single Rudder
is insufficent on account of being cut away at Bottom The Double Rudders will
Enable Ships to take all Harbours with greater Safety. I would recommend the
Spectacle of the main piece of Rudder to be punched out so as to give as much
strongth in way of Main Shaft as in any part of main pieco I would also recommend
that the Rudders be one inch thicker at the after part then at the fore part so as to
Enable the Rudder to Bite more Keenly when the Wheel is moved.
The greatest advantage will be proved in case of vessels loosing their Original
Single Rudder which as been too often the caso of the past having becoine
alltogether unmanagable at Sea, but the additional Rudder will be capable of
taking charge of any vessel under such Extraordinary Circumstances and will
be the means of saving Crew Ship & Cargoc, which must reduce the Risk of all
concerned.
No 1 Elevation plan shews the perfect Double Ruddered stern frame.
No 1 plan shewa connection of chain & on Deck.
No 2 shews the loss of the Original Rudder.
No 3 shews the loss of the Original Rudder and part of two stern posts and a
portion of Keel end.
No 4 shews a perfect Double Ruddered stern frame of a ship.
The aditional Rudder may be added to vessels of the proasent day at a small cost
the stern frame can be made of steel or Iron and the two stern posts to go up
through the main deck and the Rudder trunks for safety and strength the whole
Invention can be added to a vessel that is now at work without Disfigerment and
will be able to carry out every advantage as shown in the fore part of the
specification.
Haveing now particularly discribed and asertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First An Improved Double Ruddered Stern Frame for Vessels as shown and
Discribed.
