PROVISIONAL SPECIFICATION.
An Improved Coupling Link, more especially intended for Use in
Connecting Chains Together, but applicable also to other
analogous uses.
I JOHAN VIS of Nieuwe Vaart, Amsterdam in the Kingdom of Holland,
Engineer do hereby declare the nature of my invention to be as follows:-
My invention has for its object to provide a simple device by which chains or
other articles can be connected together with great facility and so that the
connection is as strong as the other portions which are connected by it.
According to my invention I form the device of two parts each having an eye at
one end and at the other end a part turned inwards so that when the two parts are
placed together the turned in end of each can be passed through the eye of the
other part, there being preferably a shoulder formed at such a distance inwards of
the ends which pass through the eyes as to form a bearing for the eye and to leave
a portion projecting from the eye sufficient to be upset or rivetted over to secure
the parts firmly together. In using the device one of the parts is passed through
one of the parts to be connected (say through a link of one length of chain) and
the other of the parts of the device is passed through the other of the parts to be
connected (say through a link of another length of chain) and the respective
turned in ends are passed through the respective eyes and the projecting parts of
the said ends may then be upset or rivetted over so as to constitute the device a
secure and strong connection.

COMPLETE SPECIFICATION.
An Improved Coupling Link, more especially intended for Use in
to other
Connecting Chains Together, but applicable also
analogous uses.
I, JOHAN VIS of Nieuwe Vaart Amsterdam in the Kingdom of Holland
Engineer do hereby declare the nature of my invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention has for its object to provide a simple device by which chains or
other articles can be connected together with great facility and so that a strong
connection is formed between the parts so connected.
According to my invention 1 form the device of two parts each having an eye at
one end and at the other end a part turned inwards so that when the two parts are
placed together the turned in end of each can be passed through the eye of the
other part there being preferably a shoulder formed at such a distance inwards of
the ends which pass through the eyes as to form a bearing for the eye and to leave
a portion projecting from the eye sufficient to be upset or rivetted over to secure
the parts firmly together. In using the device one of the parts is passed through
one of the parts to be connected (say through a link of one length of chain) and
the other of the parts of the device is passed through the other of the parts to be
connected (say through a link of another length of chain) and the respective
027

page_text: turned in ends are passed through the respective eyes and the projecting parts of
the said ends may then be upset or rivetted over so as to constitute the device a
secure and strong connection.
In the accompanying drawings I have shown various forms of connecting links
or devices constructed according to my invention but I do not limit myself to the
precise forms shewn.
Figures 1 & 2 shew in views at right angles to each other, one of the two parts
constituting the link. The other part is made similarly.
Figures 3 and 4 shew in views at right angles to each other the two parts of the
link secured together. When thus secured together they would of course hold
between them the parts to be connected thereby but I have not shewn these in the
drawings. Each part of the link has an eye A at one end and an angled or turned
in part B at the other end which turned in or angled part is made somewhat cup
shaped as shewn at 6 in Figure 1 to facilitate rivetting. is a shoulder extending
partly round the turned in or angled end to form a bearing for the inside of the
eye of the other part. In using the device one of the parts of the link or device is
passed through one of the parts to be connected and the other of the parts of the
link or device is passed through the other of the parts to be connected and the
respective ends B are passed through the respective eyes A and the outer portions
of the ends B, which project are upset or rivetted over as shewn at b³.
Figures 5 to 8 are views corresponding to Figures 1 to 4 shewing a narrow
shoulder all round at 4 instead of the shoulder & shewn in Figures 1 to 4.
Figures 9 to 12 are views corresponding to Figures 1 to 4 but shewing the
ends B and eyes A made conical as at in place of the shoulders shewn in the
other figures.
Figures 13 to 16 are views corresponding to Figures 1 to 4 shewing the eyes A
and ends B of elliptical form so that the heads through which the eyes pass can be
made to project less sideways if desired for any particular application of the device.
In these figures I have shewn the shoulder as being made of a combination of the
shoulders shewn in Figures 1 to 4 and Figures 5 to 8.
Figures 17 and 18 are views at right angles to each other of a link or device
studded at d and such a stud can be applied to any of the other forms of the
device.
The said stud may be applied in any suitable way for instance as a simple strut
between the parts or it may be connected to one of them or it may be welded to
both after the device has been used to connect the articles to be joined.
In the several Figures 5 to 18 I have marked the parts which correspond with
those shown in Figures 1 to 4 with the same letters of reference.
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. A coupling link or device constituted by two parts each having an eye at one
end and at the other end a part turned inwards or angled so that when the two
parts are placed together the turned in or angled end of each can be passed
through the eye of the other part and secured substantially as herein before
described.
2. The particular constructions of such connecting links or devices as herein-
before described and shewn in the respective figures of the accompanying
drawings.
