I WILLIAM HENRY MOODY of Linden Villa, Millbrook Road, Freemantle near
Southampton Hants, Dentist, do hereby declare the nature of my said invention
for "AN IMPROVED APPARATUS FOR STOPPING A SHIPS WAY AND ALSO FOR
ALTERING HER COURSE WHEN DESIRED" to be as follows:-
The invention relates to the attachment of plates of rectangular, or square form
to one or to both sides of a vessel, said plates can be lowered and be caused to open
outwards from the side or sides of the ship, to retard and prevent the water
passing easily by or past the vessel, in order to produce an impediment to her
advance.
2
The plates may be placed forward at the bow, amid-ship, or aft; or on all the
above named parts, according to requirements.
When the plates are used on one side only; the vessel quickly acquires a strong
turning power, moving away from her first direction, according as the plates are
lowered on her port, or starboard side.
The plates are preferably curved, like the blade of an oar, so as to catch, and
hold the passing water, and they can be worked by steam, capstan, or other
arrangement according to whether the vessel be a steam, or sailing ship.
The plates are arranged to be hauled up and lowered by chain and tackle, or
other arrangement most convenient to the vessel. The plates are fitted on iron, or
steel rods placed outside the ship, and are easily raised, or lowered on them.
The ends of the rods fit in sockets which are bolted on, and through the plates,
or ribs of the ship.

.
The invention can be applied to any description of steaming, or sailing, craft,
large or small, and will not interfere with her build, accomodation of passengers,
stowage of cargo, or sailing power.

page_text: I WILLIAM HENRY MOODY of Linden Villa, Millbrook Road, Freemantle near
Southampton, Hants, Dentist, do hereby declare the nature of my said invention
for "AN IMPROVED APPARATUS FOR STOPPING A SHIP'S WAY AND ALSO FOR
ALTERING HER COURSE WHEN DESIRED," 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 the attachment of plates of rectangular square, or other
form to one or to both sides of a vessel, said plates can be lowered and be caused
to open outwards from the side or sides of the ship to. retard and prevent the
water passing.easily by or past the vessel in order to produce an impediment to her
advance.
The manner of carrying this invention into effect will be understood by the
following description with reference to the annexed drawings. Figure 1 represents
the side of a steamer with plates A. A. The plates A A may be placed forward at
the stem, bow, amid-ship, or aft or on all the above named parts, according to
requirements, and held in position by rods B B upon which they are raised or
lowered by chains C C or otherwise.
When the plates A A are used on one side only, the vessel quickly acquires a
strong turning power, moving away from her first direction, according as the plates
áre lowered on her port or starboard side.
T
Figure 2 shows the bows of a vessel with the plates A. A of rectangular form
lowered into the water on the guides: B B by means of chains or wire ropes C C.
In Figure 1 an arrangement for the stern of a vessel which by reason of its
curvature or lines will not permit solid plates A. A to be raised and lowered
conveniently is shown. The plates AA in this example are made of several
separate plates hinged together to adapt them to the shape of the vessel and swing
thereto as at D D. Thèse plates are made of a form to fit over the tunnel of the
propellor shaft. The plates A. A when out of action lie close alongside the vessel
or may be arranged to fit into a recess and may be operated by suitable lever or
other arrangements.
The chains, cables or wire ropes CC for raising or lowering the plates may run
through tubes or tunnels or over rollers blocks or drums as convenient and may be
worked by capstan (in which case multiplying gear is required) winch, steam
windlass or in any suitable manner according to the build and character of the
vessel on which the plates A A are employed.
>
The plates A. A are preferably curved, like the blade of an oar,.or otherwise so as
to catch, and hold the passing water as shown at Figure 3, but may be arranged
to open against the water if desired.
Figure 4 is an elevation of a similar plate A hinged at H H upon the rod B,
which rod B has a bracket J fixed at each end for attaching it to the vessel. The
rods may be pivotted and built in recesses if convenient. The plates A. A are
provided with eyes K K or blocks to receive the chains or ropes for hauling.

page_text: The plates may be of wrought or galvanized iron, steel, wood, copper, or other
materials and consist of several plates or pieces braced together or otherwise
attached fitted on iron or steel rods B B placed outside the ship, and are easily
raised or lowered on them. The ends of the rods may fit in sockets (Figure 5)
which are bolted on, and through the plates or ribs of the ship, the rods being free
to turn in said sockets or may be bent and rivetted to the ship. The invention
can be applied to any description of steam or sailing craft, large or small, and will
not interfere with her build, accomodation of passengers, stowage of cargo, or
sailing power.
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
་
First. The improved means or apparatus shown in the annexed drawings for
stopping a ship's way in the manner described.
Secondly. The employment of plates capable of being raised out of and lowered
into the water upon rods at the sides of a vessel at the stem and at the stern if
desired said plates swinging upon rods in such a manner that they may be always
under water or raised out of the water when not-in use in the manner set forth.
Thirdly. The employment of plates at the bows of the vessel in such a manner
that when not in use the pressure of the water assists in holding' them against the
stem of the said vessel.
