Complete Accepted, 3rd June, 1887.
We DAVID HENRY HAGGIE and GEORGE ALFRED HAGGIE, both of the Wearmouth
Patent Rope Works, Sunderland, in the County of Durham, Manufacturers of Iron
and Steel Wire rope do hereby declare the nature of this invention to be as follows:-
The improvements relate to the manufacture of wire ropes.
-
The object of the invention is to promote the lasting qualities or to increase the life
of a rope or cable.
In carrying our invention into effect we protect each strand of the rope or cable, or
a number or portion of them, with a winding, binding or covering of metal springs to
prevent friction on the inner strands of the rope.
A form of rope according to our invention and of a convenient arrangement, has an
interior core around which is any number of strands composed of wires necessary to
make the rope the required size each strand having wire wound or coiled spirally
around it so as to encase it and protect the strands from injury.
Although advantage will be derived by covering the whole of the strands with the
springs or covering, in some cases we do not find it requisite to cover the whole
of them.

page_text: Improvements in the Manufacture of Wire Ropes.
We DAVID HENRY HAGGIE and GEORGE ALFRED HAGGIE, both of the Wearmouth
Patent Rope Works, Sunderland, in the County of Durham, Manufacturers of Iron
and Steel Wire Rope, 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 improvements relate to the manufacture of wire ropes
The object of the invention is to promote the lasting qualities or to increase the
life of a rope or cable by protecting individual strands.
In carrying our invention into effect we protect each strand of the rope or cable, or
a number or portion of them, with a winding, binding or covering of metal springs
to prevent friction on the inner strands of the rope applied individually to the strands.
A form of rope according to our invention and of a convenient arrangement, is
shown in the accompanying drawing by Figure 1 in side view and by Figure 2 in
cross section Figure 3 shows a side view and Figure 4 a cross section of one of the
strands separately. The rope of which a portion is shewn thus constructed has an
interior core a around which are disposed the six strands 1, 2, 3, 4, 5, 6 but it may be
any other convenient number of strands composed of wires necessary to make the
rope the required size each strand is shewn having wire c wound or coiled spirally
around it so as to encase it and protect the strands 1, 2, 3, 4, 5, 6 from injury.
Although advantage will be derived by covering the whole of the strands with the
springs or covering, in some cases we do not find it requisite to cover the whole
of them.
We are aware that ropes composed of strands have been as a whole protected by
binding spirally around the assemblage of strands and such a protection as long as it
remains intact would serve a good purpose although it would fail to do that which the
present arrangement will effect; for any fracture in the binding frees the spiral coils
for a considerable distance whereas in our improved rope the coils are locked at
each turn. Again, we are aware that it has been proposed to bind around the separate
strands with leather and other soft materials in order to give a springiness to a wire
rope in imitation of a hemp one but such an arrangement using a material for the
binding which from its perishable nature would not last and from its compressibility
would be liable to displacement would not effect our object.
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 :-
The construction or manufacture and use of a wire rope having its strands or some
of them bound or wound or encased with wire or metal spring of substantially round
cross section to protect the same substantially as described.
