PROVISIONAL SPECIFICATION.
An Improved Detachable Coupling, applicable to Wire Ropes,
Chains, and the like.
We, THOMAS BARROW Ship Repairer, of 11 Wadham Terrace, and THOMAS
FREDERICK ADAMSON, Ship Store Merchant, of Exchange Buildings both in
Tyne Dock in the County of Durham, do hereby declare the nature of this invention
to be as follows:-
This invention relates to an improved detachable coupling applicable to wire
ropes chains and the like.
In carrying our invention into practice we form in for example the side of a link
or ring an opening or cross-cut and we taper off both ends or sides to preferably
wedge-shaped or bevelled points or edges converging towards each other so that a
similar formation on another similar link or ring or eye can be slipped over or
through same and then turned into the required position for use.
The particular formation of the opening or openings or cross-cuts or edges
or their positions with regard to the eyes or links can be varied to suit
circumstances.
The eyes or links can be used if desired in combination with a thimble arrange-
ment for taking a wire rope and for many purposes for example in trawling gear
the invention should be very useful.

An Improved Detachable Coupling, applicable to Wire Ropes,
Chains, and the like.
We, THOMAS BARROW Ship Repairer of 11 Wadham Terrace and THOMAS
FREDERICK ADAMSON Ship Store Merchant of Exchange Buildings, both in
Tyne Dock in the County of Durham, 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 :-
This invention relates to an improved detachable coupling applicable to wire
ropes chains and the like.
In carrying our invention into practice we form in for example the side of a link
or ring an opening or cross-cut and we taper off both ends or sides to preferably
wedge-shaped or bevelled points or edges converging towards each other so that a
similar formation on another similar link or ring or eye can be slipped over or
through same and then turned into the required position for use.
The particular formation of the opening or openings or cross-cuts or edges
or their positions with regard to the eyes or links can be varied to suit

page_text: The eyes or links can be used if desired in combination with a thimble arrange-
ment for taking a wire rope and for many purposes for example in trawling gear
the invention should be very useful.
We will fully describe our invention with reference to the accompanying
drawings in which Figures 1 and 2 show respectively side and front elevational
views and in the following description like marks of reference indicate like
parts.
Referring to the drawings in a link or ring such as L is formed an opening or
cross-cut C and both ends of the link or ring so cut through are bevelled off as
shown at D more or less to a point.
The link or ring intended to be coupled to the said link L has a similarly formed
opening or cross-cut in it and by placing two such cross-cut links or rings opposite
to each other and at or about right angles to each other the bevelled edges on one
link can be passed through the bevelled edges on the other and then the ring or
link can he turned round or over to take its normal position as shown in dotted
lines at E. The act of detachment can be similarly performed.
For coupling or uncoupling wire ropes we form in one with or as part of the
link La thimble T through or round which the rope can be passed and bound
in the ordinary way.
By these simple means an effective and economical coupling is effected.
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. An improved detachable coupling consisting in cross-cutting the side of a
ring or link and in bevelling the edges or ends so formed so that a correspond-
ingly formed ring or link can by firstly placing it at or about right angles. to
the other ring or link be passed through the cross-cut and coupled to it or
detached therefrom substantially as and for the purposes herein set forth.
2. An improved detachable coupling consisting in cross-cutting the side of a
ring or link and in bevelling the edges or ends so formed so that a correspond-
ingly formed ring or link can by firstly placing it at or about right angles to
the other ring or link be passed through the cross-cut and coupled to it or
detached therefrom in combination with a thimble T adapted to take a wire or
other rope substantially as herein set forth.
