Improvements in Lee Wings for Vessels.
I, NATHAN COOPER JESSUP, of West Hampton Beach, Town of Southampton,
Suffolk County, State of New York, United States of America, Inventor, do
here oy 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 lee wings for vessels, and aims to provide certain
improvements in such wings and in their application to the hull of the vessel.
According to my invention I provide the vessel with a solid keel having two or more
resses penetrating its solid body laterally, but not entirely traversing the width of
die keel.
I mount my improved lee wings movably in these sockets in such manner
that they can at will be shifted either entirely within the socket or to project_at
right angles to the vertical axis of the keel from the socket. The wing at the lee
side is thus projected to catch the water and prevent the leeway in sailing, the
other wing being then disposed within its socket. On changing the course the
projecting wing is moved in and the opposite wing projected out, it being then on
the lee side.
In the accompanying drawings which illustrate certain adaptations of my
invention,
Fig. 1 is a fragmentary plan view partly in horizontal section through the
sockets, of the bottom side of the hull of the vessel;
Fig. 2 is a fragmentary cross section thereof through the sockets;
Fig. 3 is a fragmentary plan view partly in horizontal section of the keel of the
vessel;
and
Fig. 4 is a fragmentary cross section showing a modification;
Fig. 5 is a plan view of the under side of a vessel showing another modification,
Fig. 6 is a fragmentary section of the keel thereof cut on the line 6-6.
Referring to Figs. 1 and 2, let A indicate the hull B the keel, C the lee wings,
the sockets therefor, E the gears for manipulating the wing, F the shafts carrying
te gears, G a segment of gear teeth on the gears, H gear racks on the wings,
() are
J projecting stops on the latter and K co-operating stops on the gears E.
ndles on the shafts F for operating the latter.
sa
According to my invention the keel B is constructed with a solid bottom face N
tr versing its entire width, with a solid web L traversing its entire depth between
1 sockets D, and with solid portions M traversing its entire width and depth at
th ends of said sockets, whereby the keel can ride on the blocking during con-
st uction or repair of the vessel, or can pass over or rest on any substance of any
ad without impairing the sockets D or their contacts.
According to another feature of my invention I provide the shallow sockets D
each independent of the others in the sides of the keel itself, and provide shallow
wings C in these sockets. Preferably the wings and sockets are of equal depth,
whereby when moved in the wings abut against and are stopped by the inner side
of the sockets. Preferably the wings are constructed with stop projections J,
those shown being concave and corresponding in curve to the inner pitch line of the
gear teeth G, projecting at rear of the gear E, which stop engages the segment K
of the gear when the wing is projected, and thereby the outward movement of the
latter is limited. Preferably the corner at the front of the wing is bevelled
off at I.

page_text: In operation the wing to be projected is shifted by turning the handle O o' the
shaft F, and the wing at the other side is moved in in the same manner.
When
projected the wing catches the water on the lee side of the keel and tends to hold
the vessel against leeway, as usual with such wings.

In the modification shown in Fig. 3 the hull is lettered A', the keel B its
bottom face N', its web L', its solid part M', the sockets are lettered D' the
wings C', the gear E', its teeth G', its shaft F', its stop K', the rack on the win H',
and the stop thereon J. The construction and operation is identical with hat
described as to Figs. 1 and 2, with the exception that the wing is taperinging
pivoted at its front end on a pin e, and swinging on this pin in moving from the
open to the closed position, and the socket is constructed with a correspon ing
taper.
ng
In the modification shown in Fig. 4, the hull is lettered A", the keel B, its
bottom face N", its web L", the sockets D", the wings C". In this construcion
the wings fold into the sockets, being fulcrumed at their lower edges on pin C,
and carrying at their inner sides eyelets, to which are connected manipula
cords F which rise through conduits a traversing the keel. The underside K of
the sockets serves to limit the unfolding movement of the wings. The windward
wing is folded up by tautening the cord and the lee wing is unfolded by looser ing
the cord, whereby it projects to leeward of the keel.
In the modification shown in Figs. 5 and 6 the hull is lettered A", the keel B,
its bottom face N, its solid part M, the socket is lettered D, the wing C
the gear E¹¹, the rack on the wing H, and the stop thereon J
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 :-
1. In vessels, the hull and keel, the latter constructed with sockets in its side
faces and a solid wall L intervening between said sockets, in combination with a
lee wing movably mounted in cach of said sockets, when moved in one direction
projecting laterally from said keel for preventing leeway, and when moved in the
other direction moving within its socket and means for moving said wings,
substantially as set forth.
2. In a vessel, the hull and keel, the latter constructed with a plurality of
sockets in each of its side faces, with a solid web L between said sockets, with a
solid under face N beneath said sockets, and with solid portions M between the
ends of said sockets, in combination with lee wings for each of said sockets, ar
means for moving said wings, substantially as set forth.
3. In a vessel, the hull and heel, in combination with a lee wing C caried 1
the keel and having rack teeth II and stop projection J, and a gear E having a
shaft F for manipulating it and constructed with a toothed segment G engagi
said rack and a segment K in the path of and engaging said stop J for limiting
movement of the wing, substantially as and for the purpose set forth.
4. In a vessel, the hull and keel, the latter constructed with a solid bott
face N, and having a socket above said face, in combination with a lee-wing C
said socket, movable outward therefrom, and having a stop J, and a gear f
moving said wing standing in the path of said stop J, substantially as and for th
purpose set forth.
