I THOMAS O'ROURKE JAMESON of 87 William Street, Brooklyn in the County of
Kings and State of New York United States of America, Master Mariner do hereby
declare the nature of this invention to be as follows:-
My invention has for its object to provide means for quickly and readily attaching
gibs to their stays and detaching thein therefrom, and it consists of a hank of simple
construction which may be advantageously applied to other portions of the rigging of
a vessel.
I will describe my invention as applied to a gib and gib-stay, but I do not limit
myself to that application.
The hank is made in two semi-circular parts hinged together at one end and at the
other end furnished with discs which are parallel to one another when closed, and with
a locking device. These discs are of such a size as to cover the eyelets which are
usually inserted in the sail just within the leech rope. One of the discs carries a pin
which is attached to or made integral therewith and projects centrally from its inner
face, which pin, when the hank closed, passes through the sail into and through an
aperture in the opposite disc. The pin is provided with a circular shoulder and a
reduced outer end, which outer end has an annular groove cut therein near the
extremity. The shoulder serves to limit the approach of the contiguous faces of the
discs to the eyelets, completing the circle and preventing any chafing of the leech.
The other disc has a recess within which a semi-circular dog is held by a shank
which passes out from the disc and at its outer end is provided with an enlarged
head or knob. This dog is retained in position in the recess by a spring which
passes through the shank at each end and bears against the walls of the recess.
In operation, the bank having been passed around the stay, the pin is entered in
the aperture of the disc and the point of the pin, which is taper, raises the spring-
actuated dog. The grooved portion of the pin enters the recess and thereupon the
dog drops into the groove and locks the parts together.
To remove the hank the knob of the shank is grasped and the dog thereby with-
drawn from the groove in the pin and the bank may then be opened outward upon
the hinge and detached.

1, THOMAS O'ROURKE JAMESON, of 87, William Street, Brooklyn, in the County
of Kings, and State of New York, United States of America, 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 following
statement:
My Invention has for its object to provide incans for quickly and readily attaching
jibs to their stays and detaching them therefrom; and it consists of a bank of
simple construction, which may be advantageously applied to other portions.of the
rigging of a vessel.
The Invention consists in the construction and combination of the several parts, as
will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion, in which figure 1 is a representation of a portion of a jib and jib stay connected
by my improved banks; figure 2 is a sectional view of the same, enlarged, taken
through the line of figure 1; and figuro 3 is a side elevation of the hank, with
the cap covering the locking device removed. Similar letters of reference indicate
corresponding parts in all the figures.
I will describe my invention as applied to a jib and jib-stay; but I do not limit
myself to that application.
manner.
A represents a sail, denominated a jib, and B the stay thereof. To the left of the
sail, just within the leech rope C, a series of eyelets Dare inserted in the ordinary
E represents the bank, which is made in two semicircular parts hinged to
each other at one end in such a manner that the hinge part of the hank may have a
smooth inner surface to slide along the stay B. Upon the free ends of the hank
sections, discs F and F are formed in such a position as to be parallel with each
other when the said free ends are closed upon the sail, and the discs F and F are
designed to be made of such a size as to cover the eyelets D in the sail A. One of
the discs F carries a pin G which is attached to, or made integral therewith, and
projects centrally from its inner face, which pin when the hank is closed, passes
through the sail A into and through an aperture a in the opposite disc F¹, as shewn
in figure 2. The pin G is provided with a circular shoulder and a reduced outer
end which outer end has an annular groove 12 cut therein near the extremity.
The shoulder serves to limit the approach of the contiguous faces of the discs to the
eyelets, completing the circle and preventing any chafing of the leech. The disc F1
has a central recess d within which a semi-circular dog d' is held by a shank d²
which passes out from the disc and at the outer end is provided with an enlarged head
or knob e, as shewn. in figure 3, whereby the inward motion of the dog is limited.
e is a spring which passes through the shank, and bears at each end against the walls
of recess for the purpose of retaining the dog in the position to which it may be
set in the recess d.

page_text: In operation, the hank having been passed around the stay, the pin is entered in
the aperture of the disc F, and the point of the pin which is taper raises the spring
actuated dog. The grooved portion of the pin enters the recess d, and thereupon
the dog drops into the groove and locks the parts together.
To remove the hank, the knob e is grasped and the dog thereby withdrawn from
the groove in the pin, and the hank may then be opened outward upon the hinge, and
detached.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that
what I claim is ;-
1. A sail hank, constructed substantially as herein shewn and described in two
semi-annular parts hinged to each other at one end, having opposing discs integral
with their other ends, one disc provided with a grooved pin adapted to pass through
the opposite disc, which disc is provided with a central interior recess, and a spring
actuated dog adapted to enter the groove of the pin, substantially as shewn and
described.
2. A sail hank, consisting of two semi-circular parts hinged to each other at one
end, provided with opposing discs F F¹, the disc F having attached to it an inwardly
projecting pin G having a shoulder & and annular groove 62 and a tapering extremity,
and the disc F' being provided with a transverse aperture a, an interior longitudinal
recess d and a spring actuated dog d' adapted to slide in said recess d, and engage
the groove in the said pin G, substantially as shewn and described, and for the purpose
herein set forth.
3. The combination with a sail and the stay for said sail, of the hank E formed in
two semi-circular parts hinged to each other at one end, having opposing discs F, F1,
integral with their outer ends, the disc F being provided with an integral grooved
pin G adapted to pass through the opposing disc F which disc is provided with a
central integral recess d and a spring actuated dog dadapted to enter the groove in
said pin, substantially as shewn and described.
