COMPLETE SPECIFICATION.
Improvements in Shackles and Coupling Links.
We, WILLIAM HODGE, Blacksmith, and JOHN PEARSON, Contractor, both of
Timaru, in the Provincial District of Canterbury and Colony of New Zealand, do
hereby declare the nature of our invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a very simple and effective "split-link centre-pin
hook," which we have designed with the object of supplying a long felt want
namely, an easily adjustable and practically unbreakable hook for harness or for
general use.
To attain this object we have constructed a split-link of two separate parts, each
having a central collar extending half the width of the link so that each meet in
the centre thereof.
These collars are connected by a centre pin which forms the axis on which they
are capable of being turned in opposite directions, thus forming an adjustable link
and hook combined.
Our split-link centre-pin hooks may be constructed of malleable iron, steel, or
other suitable metal and may be made in various forms to suit different
requirements. In order that our invention may be better understood we will
now proceed to describe the annexed sheet of drawings illustrating same wherein :
Fig. 1 is a side view of a plain split-link centre-pin hook closed.
Fig. 2 is an end view of same.
Fig. 3 is an end view showing the two parts of the link open.
Fig. 4 is a side view of a split-link centre-pin hook adapted for use in harness;
one end of each link being formed into an eye through which a slotted pin passes.
Fig. 5 is an end view of same.
Fig. 6 is a side view of the slotted pin.
Fig. 7 is a section of same taken through slot.
Referring to Figs. 1, 2, and 3, A A' are the two parts of the split-link, each
having a collar a through which the centre pin 6 is passed and then riveted at
either end, thus connecting the two parts of the link together and enabling them to
turn as shown in Fig. 3. Referring to Figs. 4, 5, 6, and 7, B B' are the two parts
of the split-link each having a collar 6 through which the centre pin c is passed and
rivetted as described for Figs. 1, 2 and 3.
One end of each part of link is formed into an eye as shown, through which the
pin C is passed; this pin has a lip or lug d at one end, and two slots e, e, on one
side, into which the said eyes fit, thereby keeping the other ends of the link closed;
by turning the lip or lug d, the slots e, e, release the eyes and enables the pin C to
be drawn out and the other end of link opened.
We desire it to be understood that we do not confine ourselves to the precise
form or shape of the split-ring centre-pin hooks as shewn in the annexed drawings
as they may be made of various shapes without departing from the nature and
object of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
:―
A split-link, centre-pin hook, consisting of two separate parts such as A A¹

page_text: (Fig. 5) and connected by a centre pin, forming the axis on which each part is
capable of being turned in opposite directions for opening and closing, substantially
as hereinbefore described and illustrated in the annexed drawings.
Dated this Ninth day of June A.D. 1893.
