I, JOHN NICHOLAS KEAGAN, of 1, Rockstone Terrace, Stopford Road, St.
Heliers, Jersey, Master Mariner, do hereby declare the nature of this invention
to be as follows:-
My invention pertains to improvements in and relating to the reefing of sails
and has for its object to provide means for the greater ease and rapidity of
reefing.
My invention consists in means for the reefing of square or quadrilateral sails
from the foot, in which the foot of the sail is wound upon a spar or roller
carried upon the bottom yard, so that the reefing is rendered positive and any
area of sail may be presented to suit requirements. My invention is applicable
to all square or quadrilateral sails such as top sails, and top gallant sails.
In carrying my invention into effect as applied to a top gallant sail I mount:
upon the top mast, which may be provided and shrouded in any suitable manner,
a yard or spar at the extremities of which brackets are provided which hold
and retain the extremities of a spar or roller upon which the foot of the sail is
secured, and is capable of being wound. At the extremities of this spar or
roller are provided pullies about which reefing halyards, are wound which are
passed along the sides of the spar to sheave blocks which may be mounted at,
a convenient adjacent part of the top mast, reeving through such sheave blocks
and passing down to the deck where they are manipulated. The top yard is
provided with a throat ring or collar which embraces the mast head and enables'
the yard to pass up or down the mast, an halyard being secured at a convenient.
part and being passed through a sheave block fixed to the upper extremity of
the top mast and downwardly to deck.
Upon the raising of the top yard by means of the halyard from deck, the sail
is unfolded from the spar or roller secured to the bottom yard, while the reefing
halyards are wound round the terminal pullies secured to the spar or roller so
as to enable the positive winding or reefing of the sail by tension exercised upon
the reefing halyards. By such means the sail may be unfurled or reefed easily
and rapidly.
I do not confine the application of my invention to any particular square
or quadrilateral sail nor do I confine myself to the means of mounting the upper
and lower yards as hereinbefore described, as such may be varied as also the
incidental rigging to suit requirements of particular vessels or sails to which
my invention may be applied.

page_text: Improvements in and relating to the Reefing of Sails.
I, JOHN NICHOLAS KEAGAN, of 1, Rockstone Terrace, Stopford Road, St.
Heliers, Jersey, Master Mariner, 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 folowing statement:-
-
:
My invention pertains to improvements in and relating to the reefing of sails
and has for its object to provide means for the greater case and rapidity of
reefing.
My invention is illustrated in the accompanying drawings in which it is
illustrated diagrammatically as applied respectively to an upper topsail, lower
topsail and double courses.

My invention consists in means for the reefing of square or quadrilateral
sails from the foot, in which the foot of the sail is wound upon a spar or roller
carried upon the bottom yard, so that the reefing is rendered positive and any
area of sail may be presented to suit requirements. My invention is applicable
to all square or quadrilateral sails such as top sails, and top gallant sails.
In carrying my invention into effect as applied to a top sail, or a top gallant
sail A of the accompanying drawings I mount upon the top mast E which may
be provided and shrouded in any suitable manner, a yard or spar F at the
extremities of which brackets are provided which hold and retain the extremities
of a spar or roller G upon which the foot of the sail A is secured, and is capable
of being wound. At the extremities of this spar or roller G are provided pullies H
about which reefing halyards I are wound which are passed around pullies i
mounted at the extremities of the spar F and along the sides of the spar F to
sheave blocks J which may be mounted at a convenient adjacent part of the
top mast E, reeving through such sheave blocks J and passing down to the deck
where they are manipulated. The top yard K is provided with a throat ring
or collar which embraces the mast head E and enables the yard K to pass up
or down the mast, a halyard L being scoured at a convenient part and being
passed through a sheave block fixed to the upper extremity of the top mast E
and downwardly to deck.
Upon the raising of the top yard K by means of the halyard L from deck
the sail is unfolded from the spar or roller G secured to the bottom yard F' while
the reefing halyards I I are wound round the terminal pullies H H secured to
the spar or roller G so as to enable the positive winding or reefing of the sail
by tension exercised upon the reefing halyards I. By such means the sail
may be unfurled or reefed easily and rapidly.

In the drawings B represents a lower top sail or lower top gallant sail the
top of which is secured to the yard or spar F while the bottom is secured
to a spar or roller N at whose extremities are provided pullies
about which halyards R, R, are wound which pass respectively through
blocks or pullies PP fixed to yard or spar F thence around blocks Q, Q,
and passing to the deck for manipulation. The reefing of the sail B is effected
by drawing the halyards R which uncoils the halyards from the pullies and
winds up the sail about the spar or roller N., while the unfurling is effected
by means of tacks or skeats secured to the extremities of the spar or roller N,
or otherwise as convenient.
It will thus be seen that I do not confine myself necessarily to the reefing
of the sail by the rotation of a fixed bottom roller or spar.
In the drawings 'C C' represent. double courses which are mounted respectively

page_text: upon yards S, S', while the lower end of the one and the upper end of the other
are secured about a common spar or roller T, while rotation by means of
halyards U about terminal pullies V effects the reefing of each; while the
yards S S¹ close in. The halyards U pass upon the pullies W provided upon
the respective extremities of the yard S. Instead of providing a spar S¹ I
preferably hold the foot of the sail by means of tacks or skeats as is usual.
It is obvious that I do not confine myself to the arrangement of the halyards
for operating the reefing roller as herein before described, as I may modify such
arrangements without departing from the essential features of my invention.
I do not confine the application of my invention to any particular square or
quadrilateral sail, nor do I confine myself to the means of mounting the upper
and lower yards as herein before described, as such may he varied as also the
incidental rigging to suit requirements of particular vessels or sails to which
my invention may be applied.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1. Means for the reefing of square or quadrilateral sails from the foot con-
sisting of a spar or roller carried upon the bottom yard, to which spar or roller
the foot of the sail is secured and pullies upon the respective extremities of the
spar or roller about which the reefing halyards are wound operating substantially
as hereinbefore described.
2. Means for the reefing of square or quadrilateral sails from the foot con-
sisting of a spar or roller to which the foot of the sail is secured, and, pullies
upon the respective extremities of the spar or roller about which the reefing
halyards are wound substantially as hereinbefore described.
3. Means for the reefing of square or quadrilateral sails consisting of a spar
or roller to which the foot of one course and the head of another are secured
such spar or roller being provided with terminal pullies about which the
reefing halyards are wound, substantially as herein before described.
4. Means for the reefing of square or quadrilateral sails substantially as
hereinbefore described and illustrated in the accompanying drawings.
