PROVISIONAL SPECIFICATION.
An Improved Coupling Link or Shackle.
I, SYDNEY PITT of Sutton in the County of Surrey Gentleman (a communication
to me from abroad by Roderick McLeod of the City of Auckland New Zealand
Master Mariner) do hereby declare the nature of this invention to be as follows:-
The link is formed of two eyes in proximity to one another like a figure 8 with a
short length of straight stem between the two eyes. One or both of the eyes are
made to open. Part of the eye is for this purpose made capable of being turned aside
around a pin which passes crosswise through the central stem at right angles to it.
The whole of rather more than a quarter of the circumference is preferably made
capable of being turned aside in this manner and about more of the circumference
is divided into two, one part forming a continuation of the portion which can turn
around the pin joint, the other part forming a continuation of the portion which
remains fixed with the stem. If a portion of both eyes is so made capable of being
turned aside one may be made to open to one side and the other to the opposite side.
The central stem with the portions of the eyes which remain in one piece with it
would then resemble somewhat a letter S.
Or the link may be similarly formed of two parts each somewhat of the form of a
figure 3. with the central stem of the two side by side and jointed together by a
pin joint.
The drawing annexed shews a link constructed according to the invention.
Figure 1 is a side view of one form of the link and
Figure 2 an edge view of the link when closed.
Figure 3 is an edge view of the link with one oye opened.
Figure 4 is a side view of the link with the portions of the eyes which can be
turned aside separated from it.
Figure 5 is a side view and Figure an edge view of another form of the
link.
The link in this form is made of two similar parts pin jointed to one another at the
centre. The links can be made of any desired size and can be made suitable for being
used for coupling lengths of chain to eyes or to one another or for replacing
broken links or for coupling, parts. of jewellery. and for all uses for_which hooks or
links are used.

I, SYDNEY PITT of Sutton in the County of Surrey, Gentleman (a communication
to me from abroad by Roderick McLeod of the City of Auckland, New Zealand,
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 :-
The link is formed of two eyes in proximity to one another like a figure 8 with a
short length of straight stem between the two eyes. One or both of the eyes are
made to open. Part of the eye is for this purpose made capable of being turned aside
around a pin which passes crosswise through the central stem at right angles to it.
The whole of rather more than a quarter of the circumference is preferably made
capable of being turned aside in this manner and about more of the circumference

around the pin joint, the other part forming a continuation of the portion which
remains fixed with the stem. If a portion of both eyes is so made capable of being
turned aside one may be made to open to one side and the other to the opposite side.
The central stem with the portions of the eyes which remain in one piece with it
would then resemble somewhat a letter S. the portions of both eyes which are next to the
central stem would be of full section so that the central stem and portions of the eyes
extending from it may be made of sufficient strength to withstand any strain to which
the link may be subjected to prevent any strain being placed on the pin joint by which
the moveable portions of the eyes are jointed to the stem or in place of the link being
formed with two eyes it may be formed with a single eye and swivel stem.

The drawings annexed shew links constructed according to the invention.
Figure 1 is a side view of one form of the link and
Figure 2 an edge view of the link when closed.
Figure 3 is an edge view of the link with one eye opened.
Figure 4 is a side view of the link with the portions of the eyes which can be turned
aside, separated from it.
Figures 5 and 6 are side and edge views of a link with swivel stem.
In this form the stem has an eye at one end of it only and the stem is prolonged
and is at its end swivel jointed to ring as shown.
The links can be made of any desired size and can be made suitable for being used
for coupling lengths of chain to eyes or to one another or for replacing broken
links or for coupling parts of jewellery and for all uses for which hooks or links are
used.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The construction of coupling links or shackles substantially as herein before
described and illustrated in Figures 1, 2, 3 and 4 of the drawings annexed.
2. The construction of coupling links or shackles substantially as hereinbefore
described and illustrated in Figures 5 and 6 of the drawings annexed.
