Brakes or Retarders for Steam Ships, Sailing Vessels, and the like.
MARWOOD, JOHN OLIVER, Warleigh View, Bere Ferrers, Bere Alston, R.S.O.,
Devonshire, do hereby declare the nature of this invention to be as follows:-
I hinge on each side of the steam ship, or vessel, wings, or side plates, of steel,
of any required, thickness, depth, widih, or length, at the required distances,
between prow and stern, and keel and deck. Shape, of said plates conformable,
with that of the side of steam ship or vessel.
The loose, or fore parts of said plates, close tightly to side of ship, behind.
On the
projections, fixed vertically, of a V shape, the acute angle pointing forward.
Said plates being held in position by wire ropes, chains or "sweeps."
approach of danger, said ropes, chains, or sweeps, can he acted on instantly,
manually or mechanically allowing one or both, wings, or plates to open from
the side as slides at any required distance whereby the forward movement of
the ship is instantly retarded, obviating all danger of collision.

MARWOOD, JOHN OLIVER, Warleigh View, Bere Ferrers, Devon, 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:-
I hinge to sides of the vessel, plates, or wings of steel, aluminium, or any other
suitable metal of the required length, width, or thickness, to be placed at the
required, most practical distance between prow and stern, and keel, and water
line, the size and position of the said hinged plates, depending on the size, length,
and general dimensions of the vessel to which the invention is applied. The shape
of the said hinged plates to be conformable to shape and side of vessel.
When not in use, the hinged plates, or wings, close tightly to side of ship, behind
ledges or projections, fixed vertically to side of vessel, of a V shape, the acute
angle pointing forward, thus preventing wings, from impeding vessel's progress,
when not required. In applying this invention to ships in course of construction,
or sunk," so as to be on a plane with the
the hinged plates, can be "let in "
sides of vessel.
"
I place springs (spiral, or otherwise) between fore part of hinged plates and
side of shiu. which are compressed, when former, are not in use.

page_text: The wings are held in position by wire ropes, attached to the ship's engines,
or in the case of sailing vessels, to winches, or such like mechanical arrange-
ment. On the approach of danger, or the necessity of stopping the vessel, one or
both of the hinged plates can be instantly released, said springs force them off
sides of ship, the forward motion of the vessel, opens them to the required
distance (to right angles if necessary) thus the forward motion is retarded, the
impetus given by her engines. the wind, or other causes, is overcome, and
danger of collision, and so forth avoided.
To better understand the foregoing. I append the enclosed drawings.

wings b, b, and the other end wound upon drums, or cylinders f Fig. 1, and
ff Fig. 2, connected to engines winches or the like, on the rotation of which
drums, or cylinders, the wings can be drawn tightly to side of vessel, or released,
as herewith illustrated and described. Fig. 2 ledges, or projections.
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―
Improvements, in brakes, or retarders, for steam ships, sailing vessels, and the
like, as herein substantially described.
