Improvements in the Manufacture of Wire-ropes.
I, GEORGE GATTON MELHUISH HARDINGHAM, of 191, Fleet Street, in the City
of London, Civil Engineer and Chartered Patent Agent, do hereby declare the
nature of this invention (a communication to me from the Firm of Felten &
Guilleaume, of Mülheim-on-the-Rhine, in the German Empire, Cable Manu-
facturers), to be as follows:-
This invention relates to wire-ropes of the kind in which the core of each strand
consists of hemp around which the wires are laid up in one or in several layers.
According to the present invention, a wire netting or braiding is first laid
round the hemp core and then the wires are laid up round the core so braided.
The wire braiding may be one of the usual kind, viz., interwoven single wires,
or it may consist of small braided or cabled wire strands; or single wires may be
first braided round a small hemp core to form small strands, the small strands
being then braided or laid up round the hemp core of the strand proper.
According to one mode of carrying out this invention, wherein the netting or
braiding round the hemp cores of the strands is formed by interwoven single
wires, the hemp core of the rope has laid up round it strands having cores of
hemp enclosed in wire braiding, around which are laid the outer or covering
wires.
A similar rope may be constructed by employing a braiding formed of small
twisted wire strands; the hemp core of the rope having laid up round it strands
wherein are hemp cores enclosed in braidings of small wire strands, the outer
or covering wires being in two layers.
According to another construction, thin wires are first braided (or for certain
purposes cabled) round a small hemp core to form small strands; these strands
being then laid up round the hemp core of the strand of the rope. The strand
so formed is then served with outer or covering wires.
Ropes constructed in the manner above described are very ductile and free from
liability to form kinks. If used for towing or hauling, the braiding, being very
elastic, adapts itself completely to the wires; so that, in case of rupture, the braid-
ing will be destroyed later than the outer wires and consequently the thin wires
of the braiding cannot get through those of the outer wire covering.

page_text: nature of this invention (a communication to me from the Firm of Felten &
Guilleaume, of Mülheim-on-the-Rhine, in the German Empire, Cable Manu-
facturers,) 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 wire-ropes of the kind in which the core of each strand
consists of hemp around which the wires are laid up in one or in several layers.
According to the present invention, a wire netting or braiding is first laid
round the hemp core and then the wires are laid up round the core so braided.
The wire braiding may be one of the usual kind, viz., interwoven single wires,
or it may consist of small braided or cabled wire strands; or single wires may be
first braided round a small hemp core to form small strands, these small strands
being then braided or laid up round the hemp core of the strand proper.
The accompanying drawings illustrate wire-ropes constructed according to this
invention; Figs. 1 and 2 being respectively an elevation and a transverse section
of a wire-rope wherein the braiding which surrounds the core is composed of
interwoven single wires; Figs. 3 and 4 being similar views of a wire-rope wherein
small braided or cabled wire strands are employed in the composition of the
braiding; and Figs. 5 and 6 representing similar views of a wire-rope in which
a number of small hemp cores are first enclosed in a braiding of single wires, the
small strands thus formed being then laid up round the hemp core of the strand
proper.
According to the mode of construction illustrated in Figs. 1 and 2, the hemp
core A of the rope has laid up round it strands having cores a of hemp enclosed
in wire braiding 6 formed by interwoven single wires around which are laid the
outer or covering wires c c.
According to another mode of construction, illustrated in Figs. 3 and 4, a
similar rope may be produced by employing a braiding formed of small twisted
wire strands; the hemp core A of the rope having laid up round it strands wherein
are hemp cores a enclosed in braidings 6* 6* of small wire strands, the outer or
covering wires c c being in two layers.
According to a further mode of construction, illustrated in Figs. 5 and 6, thin
wires 600 are first braided round a small hemp core a* to form small strands;
these strands being then laid up round the hemp core a of the strand of the rope.
Strands so formed are then served with outer or covering wires c c and are then
laid up round the hemp core A.
Ropes constructed in the manner above described are very flexible and free from
liability to form kinks. If used for towing or hauling, the braiding, being very
elastic adapts itself completely to the wires; so that, in case of rupture, the braid-
ing will be destroyed later than the outer wires and consequently the thin wires
of the braiding can not get through those of the outer wire covering.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I claim:-
:―
1. The improved manufacture of wire-ropes substantially as herein described,
and consisting in laying up around the hemp cores of the strands a wire netting
or braiding composed of interwoven single wires, or of interwoven wire strands,
or of thin wires interwoven or twisted round small hemp cores so as to form small
strands, the latter being braided or laid up round the hemp core of the strand
proper.
2. A wire-rope consisting of a main hemp core round which are laid strands
composed of a hemp core enclosed by a wire braiding consisting of interwoven
single wires or of small cabled strands, around which the outer or covering wires are
laid up in one or several layers, substantially as set forth.
3. A wire-rope consisting of a main hemp core round which are laid strands
composed of a hemp core enclosed by a layer of small strands, the latter con-
sisting of a hemp core surrounded by a braiding of single wires, and being braided
or cabled round the hemp core of the strand proper; the outer or covering wires

page_text: being laid up around the said enclosing small strands in one or several layers,
substantially as set forth.
4. A strand for a wire-rope having a hemp core covered with a wire netting or
braiding constructed or arranged in any one of the modes herein described, and
having outer or covering wires laid up around the same in one or several layers,
substantially as and for the purposes specified.
