PROVISIONAL SPECIFICATION.
A New and Improved Chain Coupling Link.
GEORGE JACKSON, 34, Kent Street, Great Grimsby, Ships Husband,
WILLIAM SWINBURN, Wood Turner, 274; Cleethorpes Road, Great Grimsby, do
hereby declare the nature of this invention to be as follows:-
Our new and improved chain thimble link, is for connecting wire ropes or wire
warps, to chain links by means of splicing. It is for the use of fishing vessels and
all discriptions of ships use of an analogous nature. We propose to form a solid
thimble in one end of the link with a concave circular score with a much larger
basement than the opposite end of the link to admit of wire rope. For the
purpose of splicing. By this means it will have a much greater and stronger bearing
than on the ordinary and a very great advantage over the loose thimble which is
now in use. It will be a great saving in labour and material, and will prevent
the cutting of ropes, and all other parts it may come in contact with.
Dated this 10th day of March 1898.

WILLIAM SWINBURN.
A New and Improved Chain Coupling Link.
We, GEORGE JACKSON, of 34, Kent Street, Great Grimsby, Ships Husband, and
WILLIAM SWINBURN, of 274, Cleethorpes Road, Great Grimsby, Wood Turner, 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: -
Our invention relates to a thimble link for the connection of wire hempen or
other ropes or warps by eyesplicing and for general use; and is intended to
substitute the ordinary thimble used within an eye-splice to prevent chafing.
Our invention has for its object to provide a thimble that shall not be liable to
distortion nor collapse under heavy strain: and that shall not be liable to cut or
engage with ropes or parts when in use and that may be conveniently held for
splicing.

page_text: Our invention consists of a thimble in the form of a link having provided
integrally, at one extremity a boss or thimble part about which the extremity of
the rope to be connected is arranged and spliced.
Our invention is illustrated in the accompanying drawings in which
Figure 1 is a front elevation of a thimble made in accordance with our invention.
while
'
Figure 2 is a side elevation corresponding thereto.
Figures 3 and 4 are respectively front and side elevations of a modification in
design while
Figure 5 and 6 are similar views of a further modification.
In carrying our invention into effect as illustrated in Figures 1 and 2 of the
accompanying drawings we provide a link A from wrought iron, cast steel or
other suitable metal or material having formed at its lower extremity a boss
or thimble part B, having grooves C in which the extremity of the rope to be
connected may lie: thus forming lateral flanges ID which prevent ropes or parts
being cut or caught in passing in contact with them. The boss or thimble part B
is preferably provided with a central hole or core E to minimise weight.
In carrying the invention into effect according to another modification we pro-
vide the thimble part which may be of heart shape as a separate piece C₁ as
illustrated in Figures 3 and 4 of the drawings and we secure the thimble to the
link by rivets e or any suitable means.
In carrying the invention into effect as illustrated in Figures 5 and 6 we secure
the separate thimble part C₁ to the link by means of a bolt G.
By the use of a thimble link or shackle as hereinbefore described a safe and
strong connection is provided which is not liable to be affected under heavy strains.
A thimble having a link forged thereon has already been constructed, but in
that construction the thimble has been made in the ordinary manner, from thin
metal differing in no respect from the ordinary eye-splice thimbles. Such thimbles
are liable to distortion and collapse as well as to chafe and cut the ropes with
which they may come into contact which defects it is the principal object of this
invention to avoid. It is therefore desired that it shall be understood that no claim
is herein made with respect to any thimble link or combination comprising or
having connected therewith an ordinary eye-splice thimble.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what we
claim is
1. A thimble link constructed substantially as and for the purpose hereinbefore
described and illustrated.
2. A link having provided integrally at one extremity a boss or thimble part
substantially as herein before described.
