We ARTHUR THOMAS ALLEN, and HENRY CAVILL both of the Hallamshire
Engineering Works Sheffield in the county of York, Engineers do hereby declare
the nature of our said invention for AN IMPROVED CONNECTING LINK FOR REPAIRING
OR JOINING CHAIN CABLES AND OTHER CHAINS to be as follows :-
.
Our invention refers to the construction of a connecting link, to be used in
repairing chain cables or other chains when they have parted, or in joining together
lengths of cable or chain for any desired purpose.
The object is to construct a link that will readily admit the end links of the chains
that are to be joined, and that may be quickly put together and form a substantial
connection capable of sustaining the desired strain.
The link may be made of any suitable metal, but we prefer to make it, by casting it
in a tough quality of steel, and to the required shape, so that when put together it
resembles an ordinary Cable link.
The part which may be called the link proper, is made with an opening in one of
its sides of a sufficient width to admit the passage of an ordinary link of corresponding
size, and exactly opposite the said opening, a hole is made through the other side of
the link to receive a shank on the locking piece.
On each side of the beforementioned opening, but on opposite sides of the link a
portion of the metal is cut away to form a clutching arrangement to engage with the
locking piece.
The locking piece is of a T shaped configuration, the arms being shaped to
correspond with and lock into the cut out parts of the link as before described, the
body connects the two sides of the link, and the shank extending from the body passes
through the hole before mentioned, and is secured by means of a nut,
through it transversely, rivetting over the end, or equivalent means.

We ARTHUR THOMAS ALLEN and HENRY CAVILL, both of the Hallamshire
Engineering Works, Sheffield, in the County of York, Engineers, 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 refers to the construction of connecting links which are used in
repairing Chain Cables or other Chains when they have parted or come in two parts, or
in joining together lengths of Cable or Chain for any desired purpose; the object being
to construct a link that will readily admit the links of the Chains that are to be
joined, and that can be quickly put together, and permanently secured, so as to form a
substantial connection capable of sustaining the desired strain.
In order that our invention may be clearly understood and particularly ascertained
we annex a sheet of drawings illustrating same, similar letters of reference indicate
similar parts in any of the figures.
Fig. 1, is a plan of one of our links in its complete state.
Fig. 2, is a side view of same.
Fig. 3, is a link with the removable locking-piece removed.
Fig. 4, is the locking piece.
Fig. 5, is a side view of Fig. 3.
The link may be made of any suitable metal but we prefer to make it by casting it
of a tough quality of steel, and to the exact required shape as shown, so that when
put together it resembles an ordinary cable chain link as shown in Fig. 1.
We make it in two parts, the link proper marked A, and the locking piece B.
The link proper A, is made with an opening C, in one of its sides of a width
sufficient to admit a corresponding link being passed through, and exactly opposite
the opening C, on the other side of the link, we form upon each side a bisected
recess D.
Upon each side of the opening C, but on opposite sides of the link, a portion of
metal is cut away at E, but leaving a projection F.
The locking-picce B, is formed with a double forked end, the larger opening G being
to grip the link itself, and the smaller opening H, being to admit the tapered
projection I; the head of B, is shaped to fit into the cut away portions of the link, and
is provided with recesses K, to receive the parts F, on each side of the link.
Thus when the part B, is passed forward through the opening C, the opening G
receives the opposite side of the link, and on the application of force to the part B, the
two prongs L, are compelled to expand and follow the divided recess D, both on the
top and underside of the link, thus securing or locking the two parts A and B
together.
As a modification of the above means of locking the two parts together, the end of
the part B, is made into a reduced shank which fits into a corresponding hole in the

screwed on it, or a pin passed through it, or other equivalent means be used to finally.
secure it.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim, is :—
1-A connecting Link for chain Cables and other chains, constructed in the manner
substantially as hereinbefore described and illustrated.
3-In a link for connecting chains, and consisting of two parts such as A & B, the
construction of the head of B, with recesses K, to fit upon the corresponding parts F,
of the link, in combination with the divided end of B, and the bisected recess D, on
the link, or any equivalent means of finally securing the part B to the link or part A,
reference being had to the specification and drawings annexed.
