of Suffolk, of the State of Massachusetts, of the United States of
Amorian for the Invention of 66 AY IMPROVED SAIL HANK"
COMPLETE SPECIFICATION filed by the said David Granville Low at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 19th February 1872, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
GRANVILLE Low, of Chelsea, in the County of Suffolk, and State of
Massachusetts, of the United States of America, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVED SAIL
HANE," and have petitioned Her Majesty Queen Victoria to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that I am the true and
first Inventor thereof.

NOW KNOW YE, that 1, the said David Granvine Low,
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the following
statement
My said Invention is clearly represented in the accompanying
Drawings, similar letters denoting like parts in all the Figures.
In the said Drawings Figure 1 is a top view of a hank as constructed
in accordance with my Invention, the same being represented as closed;
Figure 2 is a similar view of the same as open; Figure 3 is a central
and longitudinal section; and Figure 4 is a side view of the said In-
vention. Figure 5 denotes a hank as ordinarily constructed.
The object of my Invention is to provide a simple, substantial and
effective device for connecting a jib or stay sail with its "stay," one
which can be readily applied to the stay and sail or removed therefrom
with far greater facility and ease than the hanks as ordinarily employed.
My improved hank is intended as a substitute for the common iron
hank now in use on vessels of every description which employ jibs or
stay sails and are rigged with wire ropes or stays. The objections
to hanks of the ordinary construction are that they involve too great
an expenditure of time, labor, and expense in "seizing" or lashing
them to the "stay" and sail, and besides the "lashings" often become
chafed and broken, whereby the sail is rendered loose and flappy, and
the hank becoming disconnected is often lost; my Invention completely
obviates such evils.
The nature of my Invention consists in the peculiar construction and
arrangement of the several parts as herein-after described, whereby all
lashing yarn or "seizing" is dispensed with, and a non-detachable lock-
ing bolt used in place thereof.
In the said Drawings A denotes the body of the hank, which consists of
a U-shaped metallic bar. B is the locking bolt which passes transversely
through a hole O in the lower ends of the arms a, a¹, of the hank. The
said bolt at its outer end is provided with a head b, while its inner end is
furnished with a short stud or projection c extending from its periphery
and at a right angle to its axis. Within the inner face of the arm a
and just above the bolt hole thereof is a socket or recess d to receive

page_text: the projection c of the bolt when the latter is drawn back into the
position, as shown in Figure 2, in order to afford a free and unobstructed
entrance to the eye of the hank. The said stud c is to be affixed to the
bolt after the same has been passed through the arm a, as such arm has
no slot to enable the bolt to be introduced after the stud has been
secured to the bolt, the said pin or stud so affixed serving as one of
its functions to prevent the bolt from being drawn out or becoming
detached from the body of the hank. There is also formed in the arm a¹
and above the bolt hole thereof a transverse and parallel groove or
channel e for the stud of the bolt to pass through.
also a socket fmade in its outer face and below the bolt hole, the same.
being of sufficient depth to receive the said stud and thereby lock the
bolt to the hank. g is a helical spring which is coiled around the shank
of the bolt, one end resting against the head thereof and the other
against the arm a, the object of the said spring being to maintain the
stud of the bolt in the socket ƒ when the hank is closed, and permit the
same to be readily unlocked and the bolt withdrawn whenever it may be
The said arm has

page_text: retracted and drawn back into the position as shown in Figure 2, when
the bank may be readily removed.
From the above it will be seen that a hank constructed in my
improved manner is one of great utility for the purpose designed, it
being simple, strong and reliable, not liable to get out of order, can be a
readily applied in the roughest weather, and very durable.
Having described my Invention, what I claim is, my improved hank
as described, the same consisting of the body A (provided with the bolt
receiving hole O, the groove e, the socket for the sockets f and d), and
the bolt B (furnished with the stud c and the spring g), the whole being
constructed, combined, and arranged in manner and so as to operate as
set forth.
In witness whereof, I, the said David Granville Low, have hereunto
this Wifth day of Tuhmuany 1970
