Improvements in relation to the Construction of Ships for the
Purpose of Preventing Sea-sickness.
I, THOMAS FORREST WALSH, of Newcastle West, County Limerick, Ireland,
Gentleman do hereby declare the nature of this invention to be as follows:-
This invention bas reference to improvements in relation to the construction of
ships, and has for its object chiefly the prevention of sea-sickness.
In carrying out my invention I propose to arrange floats or wings formed of
iron or other suitable material, and of suitable dimensions according to the size
or tonnage of the ship to be dealt with.
These floats or wings may be divided into sections and operated independently,
or may constitute one complete wing on either side of the vessel each to be
operated by separate mechanism so that the float or wing on the lee side may
be kept generally open or expanded, and that on the weather side open or closed
at pleasure.
These floats or wings are intended to lie flat on the surface of the water, and
are held in position by means of stay rods, one end being hinged to the longi-
tudinal centre of the floats or wings, and the other end sliding in vertical groove
plates attached to the ship's side.
The sliding ends of the stay rods may be fixed at any point in the vertical
groove plates by means of bolts or tightening screws or other suitable means,
whereby the floats or wings can be lowered or raised to any horizontal plane
according to the height of the vessel above the surface of the water.
When not in use the floats or wings may be closed up by raising the sliding
ends of the stay rods in the vertical guide plates, and lashing the floats or wings
to the ship's side in any convenient manner that experience may suggest.
Dated the 14th day of October 1893.

Improvements in relation to the Construction of Ships for the
Purpose of Preventing Sea-sickness.
1, THOMAS FORREST WALSH, of Newcastle West, County Limerick, Ireland,
Gentleman, 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 has reference to improvements in relation to the construction of
ships, and has for its object, chiefly the prevention of sea-sickness.
In carrying out my invention I propose to arrange floats or wings formed of
iron, or other suitable material, and of suitable dimensions according to the size or
tonnage of the ship to be dealt with.
These floats or wings may be divided into sections, and operated independently,
or may constitute one complete wing, on either side of the vessel, each to be
operated by separate mechanism. The floats or wings are intended to lie flat on
the surface of the water, and are hinged to vertical rods which slide in suitable
Price 8a.1

stances by rack and ratchet wheel arrangement. Diagonal stay rods are used to
maintain the floats or wings in a horizontal position.
The accompanying drawings will enable my said invention to be more readily
understood and carried into practice :-
Fig. 1, is a transverse section of an ordinary hulk showing my improved floats or
wings applied thereto;
and
Fig. 2, is an enlarged side view of the float or wing detached, with appendages;
Fig. 3, a front view showing the apparatus applied to the side of the vessel.
A, A, are the floats or wings hinged to the vertical sliding rods B, B, which
latter slide in suitable grooves C, C, fixed to the vessel's side; D, D, are the
diagonal stay rods which secure the floats or wings, and maintain them horizontally
on the water's surface. On the upper portion of the vertical sliding rods is formed
a rack with which gears a pinion E, which is operated by a crank handle F,
passing through the bulwark, and may be turned by hand or mechanical means at
pleasure.
By this arrangement the floats or wings can be raised or lowered so as to rest on
the water's surface according to the depth of water drawn by the vessel.
It is obvious that when not in use the floats or wings may be made to close up
on their hinges, and may be lashed to the ship's side in any convenient manner
that convenience may suggest.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The use and application, in connection with steamers and sailing craft of all
kinds, of apparatus consisting of floats or wings, constructed, arranged, and
operating substantially in the manner, and for the purpose herein specified and
set forth.
