AN IMPROVED ARRANGEMENT OF BOW RUDDERS
Year: 1884

page_text: I JOHANN HINRICH FOCK of Altona in the German Empire Merchant, do hereby
declare the nature of my said invention for "AN IMPROVED ARRANGEMENT OF
BOW RUDDERS" to be as follows:-
―
This invention relates to a new or improved rudder arrangement to ships, which
invention will be of great value to sea-going steamers and other sea-going vessels;
as a very effective and rapid steering can be ensured by its application and in cases,
where a vessel is proceeding at a very slow speed it will still answer to the helm,
whilst the rudders now generally in use, requires a certain and rather considerable
speed of the vessel, to sufficiently influence the course of the ship When a vessel
goes astern, this improved rudder will be of great use and especially with screw
propelled vessels it will in such case prevent the head being thrown over (aside) by.
the action of the screw.
The invention consists of a rudder at the fore part of the ship, placed inside the
stem of the vessel, between the keel and a false stem, to which the lower rows of
plates are attached instead of to the real stem as heretofore.
This false stem in connection with the front stem and keel of the vessel, are
formed into a frame applicable for the reception of this improved rudder, which
latter consequently will not project in front of the vessel and will not be liable to
be damaged by anchor or chains as other rudders would be, that have heretofore
been applied in front of vessels. The shape of the rudder may be of rectangular
triangular or other convenient form to accommodate the rudder and its frame as.
well as possibly may be to the lines of the vessel.
The rudder-post may be placed at or attached to the front end of the rudder but.
it may also be placed about a third of the length of the rudder apart from the
front in which case the rudder will be better applicable to stop the speed of the
vessel as well as to steer.
The new rudder may by gearing or chains and rollers or other mechanical
arrangement be connected to the steering mechanism of the rudder in the rear part
of the vessel, or to a separate steering gear as convenient. The improved rudder.
may either be combined with the ordinary stern rudder or it may be applied only
in case of need in which case a coupling arrangement or a separate steering gear
will be required.

I JOHANN HINRICH FOCK of Altona, Germany, Merchant do hereby declare the
nature of my said invention for "AN IMPROVED ARRANGEMENT OF BOW RUDDERS
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 a new or improved rudder arrangement to ships, which
invention will be of great value to sea-going steamers and other sea-going vessels,
as a very effective and rapid steering, can be ensured by its application and in
cases where a vessel is proceeding at a very slow speed it will still answer to the
helm, whilst the rudders now generally in use, require a certain and rather
considerable speed of the vessel, to sufficiently influence the course of the ship.
When a vessel goes astern, this improved rudder will be of great use and especially
with screw propelled vessels, it will, in such case prevent the head being thrown
over (aside) by the action of the screw.
The invention consists of a rudder at the fore part of the ship, placed inside the
stem of the vessel, between the keel and a false stem to which the lower rows of
plates are attached instead of to the real stem as heretofore. This false stem in
connection with the front stem and keel of the vessel, are formed into a frame
applicable for the reception of this improved rudder, which latter consequently will
not project in front of the vessel and will not be liable to be damaged by anchor
or chains as other rudders would be, that have heretofore been applied in front of
vessels. The shape of the rudder may be of rectangular, triangular or other
convenient form to accommodate the rudder and its frame as well as possibly may
be to the lines of the vessel.
The rudder-post may be placed at or attached to the front end of the rudder but
it may also be placed about a third of the length of the rudder apart from the
front in which case the rudder will be better applicable to stop the speed of the
vessel as well as to steer. The new rudder may by gearing or chains and rollers
or other mechanical arrangement be connected to the steering mechanism of the
rudder in the rear part of the vessel or to a separate steering gear as convenient.
The improved rudder may either be combined with the ordinary stern rudder or it
may be applied only in case of need in which case a coupling arrangement or a
separate steering gear will be required.
The invention is illustrated by the accompanying sheet of drawings in which
Fig 1 shows a side view of a vessel furnished with the new rudder in front.
Fig 2 is a ground plan of the vessel and Fig 3 a section at line a, b. Fig 4 is a
modification, showing a rudder of different shape to that of Figs 1 and 2.
S is the stem of the vessel and S₁ a false stem at some point to the rear of
forward stem S; said false stem S¹ being attached or formed to the vessel between
stem S and keel e. The space left between stem, false stem and keel is employed
for the reception of the front rudder R, which may be moved by a rudder post m
passed upward to the deck or other convenient part of the ship within a channel,
or a compartment formed by an upright bulkhead i; or otherwise as convenient.
The covering or plates in front of the vessel, terminate at the false stem S¹, leaving
the space between the front stem S and the false stem S¹ open for the reception
of the rudder. The rudder R can for sake of steering the vessel be turned at any
suitable angle as will be seen from Fig 2 of the drawings.
By forming the false stem S straight as in Fig 4 the space enclosed by the
parts S, S¹ and e attains a triangular form and the rudder R is formed accordingly.

page_text: Any other form of rudder R may be used according to the shape given to false
stem S. The invention does not relato to front rudders generally, as that is
not new.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
The improvements in safety rudders applied at the fore part of ships placed
inside the stem of the vessel between keel and a false stem to which latter the
lower rows of the covering plates are attached substantially as herein described
and shown by the drawings.
