A New or Improved Coupling Link for Chains, Warps, Ropes, and
the like.
I, JOSEPII BALL, of 5, Stanley Street, New Clee, Great Grimsby, in the County
of Lincoln, Fish Merchant, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to construct coupling links in such a manner
as to enable them to be easily attached to and detached from chains thimbles and
the like my present invention being specially suitable for connecting the various
lengths of wire rope used to form towing warps.
Now according to this invention I form coupling links in two pieces or halves
in the shape of the letter C for cable pattern chains or of any other suitable
shape to suit chains other than cable pattern.
Each portion of the link has the ends tapered to allow of one portion lying
snugly against the other when the link is closed.
Attached to the centre of one half of the link by rivetting or welding is a strut
or cross bar to the free end of which is pivotted the other half of the link.
The cross bar or strut is shouldered down to receive the rotating half of the
link and when the said portion is in place the end of the strut is rivetted over
to prevent the two halves of the link from becoming detached from one another.
In addition to forming a pivot the cross bar acts as the strut used in chain
cables.
To connect my improved link to a chain or thimble it is only necessary to
rotate the one half thereof on the pin and separate the curved ends the link or
thimble is then placed over the one end of the half link and run down to the
cross bar the two ends are then brought together and the link is secure.
Links constructed as hereinbefore described are suitable for connecting the
different lengths of towing warps mending broken chains, attaching warps
or ropes to chains and other similar purposes.
They are especially applicable to towing warps for deep sea fishing as by their
use any cutting or splicing of the warps may be done ashore instead of on board
as the different lengths of warps can be instantly disconnected one from the other
and taken ashore for alterations and repairs.
Doted this 7th day of November 1898.

I, JOSEPH BALL, of 5, Stanley Street, New Clee, Great Grimsby, in the County
of Lincoln, Fish Merchant, 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:-
The object of this invention is to construct coupling links in such a manner
as to enable them to be easily attached to and detached from chains thimbles and
the like my present invention being especially suitable for connecting the various
lengths of wire rope used to form towing warps.
Now according to this invention I form coupling links in two pieces or halves
in the shape of the letter C for cable pattern chains or of any other suitable
shape to suit chains other than cable pattern.
Each portion of the link has the ends tapered or otherwise formed to allow
of one portion lying snugly against the other when the link is closed.
Attached to the centre of one half of the link by rivetting or welding is a
strut or cross bar to the free end of which is pivotted the other half of the link.
The strut or crossbar is shouldered down to receive the rotating half of the link
and when the said portion is in place the end of the strut is rivetted over.to
prevent the two halves of the link from becoming detached from one another.
In addition to forming a pivot the crossbar acts as the strut used in chain
cables.
To connect my improved link to a chain or thimble it is only necessary to rotate
the one half thereof on the strut and separate the curved ends the link or thimble
is then placed over the one end of the half link and run down to the crossbar,
the two ends are then brought together and the link is secure.
And in order that my said invention may be fully understood I will proceed
to explain the same with reference to the accompanying sheet of drawings in
which
Fig. 1 represents side view of a coupling link for chains warps ropes and the
like constructed according to this invention.
Fig. 2 represents end view of same.
Fig. 3 shews the link open.
Fig. 4 shews a portion of one half of the link.
The same letters denote the same parts in all the Figs.
a is one portion of the link.
b the other portion thereof.
c is the strut or crossbar connecting the portions a and b the said strut being
secured firmly to the portion a by welding or rivetting and is also rivetted into
the portion in such a manner as to allow the latter to rotate thereon as shewn
by Fig. 3.
The two portions a and b are similar and are preferably circular in section
and forged between suitable dies, being shaped approximately like the letter C
for cable pattern chains or of any other required shape to suit chains other than
cable pattern.
.
Each portion ab of the link is shouldered at d d to receive the curved
portion of the other half of the link the ends of the two portions being semi-
circular in section as shewn by Figs. 3 and 4. The ends of each portion of the
link are formed with projections f and recesses 9 the projec-
tions entering the recesses
when the link is closed to prevent
ends of the portions ab
distortion while in use. Or instead of the

page_text: being semicircular in section as shewn and formed with shoulders the said ends
may be merely tapered as shewn by dotted lines Fig. 2 so as to lie snugly one
against the other when the link is in use and prevent the same from being
accidentally opened.
Links constructed as hereinbefore described are suitable for connecting the
various lengths of towing warps, mending broken chains, attaching warps or
ropes to chains and other similar purposes, and they are especially applicable to
towing warps for deep sea fishing as by their use any cutting and splicing of
the warps may be done ashore instead of on board as the different lengths of warps
can be instantly disconnected one from the other and taken ashore for alterations
and repairs.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. Coupling links for chains ropes warps and the like consisting of two similar
approximately C shaped portions connected together by means of a strut or
crossbar secured to one portion of the link the other portion thereof being
pivotted to the said strut or crossbar, the curved ends of the said portions being
tapered or otherwise formed so as to be flush with the body of the link when
closed substantially as specified.
2. In coupling links for chains warps ropes and the like the combination of
two similar approximately C shaped portions a and b having the curved ends
thereof semicircular in section and provided on the flat side with projections f
and recesses g with a strut or crossbar c secured by rivetting or welding to the
portion a and pivotted to the portion ball substantially as and for the purpose
specified.
3. Coupling links for chains warps ropes and the like constructed as shewn
by the accompanying drawing.
