I, JOHN ALEXANDER HILL, of Duke Street Liverpool, in the County of Lancaster
Master Mariner, do hereby declare the nature of this invention to be as follows:-
This invention relates to jury rudders or temporary apparatus for steering ships in
case of accident to or disablement of the rudder while at sea, and its object is to
provide an inexpensive apparatus which may be quickly and easily fixed in position
and which will effectively steer the ship.
It consists essentially of one or more plates or rudders suspended over each side of
the ship by means of chain rope or otherwise free to swivel or move on the suspender,
and actuated by means of chains or other connections.
These rudder's plates may be of any convenient size estimated according to the size
of the ship to which they are to be applied, and the shape is not of importance,
though I prefer to make one edge flat and the other curved. Two or more eyes or eye
bolts are secured to one edge of them to receive the chain or other material by which
they are suspended. This chain or suspender preferably passes through the eyes, the
plate moving about it as a centre-A shackle or other similar contrivance fastened
into the links of the chain or otherwise to the suspender prevents any movement of the
rudder plates longitudinally-Instead of passing the suspender through the eyes of the
plate, it may be shackled thereto and the plate swivel on the shackles. On the face of
the plate is fixed a stud or bracket to which is shackled rope chain or rods connected to
the steering gear or to a winch and by means of which the rudder's plates are actuated-
I prefer to fix the plates to the stream chain, which will I think be found sufficiently
strong, though other cable or rope may be employed for the purpose. The chain is
passed round the ship and as near abaft as possible, so as not to interfere with the pro-
peller, and the position of the top of the plate is a little below the water line-Two or more
Guy chains are attached to the chain passed round the ship, preferably one below and one
above each plate to bear the strain and weight of the water on the rudder plates-A
rope with blocks may be used on deck to keep the chain carrying the rudder plates
taut and a rope passed through a block at the stern of the ship connects the two
rudder plates ensuring their moving synchronously and preventing back lash.

page_text: Improvements in Jury Rudders or Temporary Apparatus for
Steering Ships.
1, JOHN ALEXANDER HILL, of Duke Street, Liverpool, in the County of Lancaster,
Master Mariner, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to jury rudders or temporary apparatus for steering ships
in case of accident to or disablement of the rudder while at sea, and its object is to
provide an inexpensive apparatus which may be quickly and easily fixed in position,
and which will effectively steer the ship.
It consists essentially of one or more plates or rudders, suspended over each side of
the ship by means of chain rope or otherwise, free to swivel or move on the suspender,
and actuated by means of chains or other connections.
Referring to the drawings :-
Figure 1 is a side elevation of a vessel fitted with my improved jury rudder.
Figure 2 end view.
Figure 3 plan of deck showing connections.
A, A are the rudder plates, one of which is applied to each side of the vessel as
near abaft as possible, so as not to interfere with the propeller G, and in such a position
that the top of the plates are a little below water line. The plates may be of any
convenient size, estimated according to the size of the ship to which they are to be
applied; the shape is not of importance, but may be made flat or curved, though I
prefer to make them as shewn on the drawing. The plates A are suspended by means
of a chain B or other suspender which is passed round the ship H, I prefer using the
stream chain for suspending the plates which will I think be found sufficiently strong
though other cable or rope may be employed. The chain B is firmly secured to the
rudder plates A. by means of shackles as shewn on the drawings at a, or by means of
two or more eyes or eye bolts secured to one edge of the plates A through which the
chain or other material by which they are suspended passes, the plate moving about it
A shackle or other similar contrivance fastened into the links of the
chain or otherwise to the suspender prevents any movement of the rudder plates A
longitudinally. Instead of passing the chain through the eyes of the plate, it may be
shackled thereto, and the plate swivel on the shackles. On the face of the plate A
I fix a stud bracket C to which is shackled rope, chain or rods D connected either to
the steering gear, or to a winch, and by means of which the rudder plates A are
actuated. Two or more Guy chains E, E, are attached to the chain passing round the
ship as shewn on the drawing, in order to bear the weight of the water on the rudder
plates A. A rope F passed round the stern of the ship connects the two rudder
plates A, A, ensuring their moving synchronously and preventing back lash, and
rope I, and blocks J, or other contrivance, may be used on deck to keep the chain B
carrying the rudder plates A, A, taut.
as a centre.

page_text: Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I wish it to be understood that I do
not claim broadly the use of plates at the sides of a ship for steering purposes, as such
have been tried or suggested pivoted or hinged to the side of the ship, but I declare
that what I claim is :-
1st. A jury rudder or temporary steering apparatus for ship's use having one or
more rudder plates shackled or otherwise attached to a chain or suspender on which
they are free to swivel or move, and by which they are suspended and held in position
at the ship's side, substantially as described and shown.
2nd. A jury rudder consisting of two or more plates in combination with a chain
or suspender passed round the outside of the ship, and held securely in position by
guy chains, the rudder plates being actuated by chains or ropes from the steering gear
or winch, substantially as described.
