Improvements in or connected with Wire Rope Manufacture.
I, CHARLES JOHN Banks of The Willows, Washington in the County of
Durham, Rope Works Manager do hereby declare the nature of this invention to
be as follows:-
:-
:
This invention relates to improvements in or connected with wire rope manu-
facture and consists in a novel method or process having for its object the elimination
of parts of machinery hitherto considered essential in this industry with a consequent
reduction in cost of manufacture both as regards labour and material.
Hitherto in the manufacture of strands for ropes it has been found necessary to
employ a machine containing or capable of containing as many bobbins as there are
wires in the strand or in the annular courses of the strand; in other words each
bobbin has hitherto carried one wire only.
Thus to compose a strand of nineteen wires by the existing system six wires
coming off six separate bobbins are first spun round one as a core making seven
wires in all; by a second operation a course of twelve wires is then spun round the
seven aforesaid making nineteen in all. The latter operation requires a twelve-
bobbin machine to spin the twelve wires and in like manner if strands of greater
Dumbers of wires are required so will a machine containing a number of bobbins
corresponding to the greater numbers of wires be rendered necessary.
My invention consists in a method or process by which with for example a six-
bobbin machine I can spin a strand composed of any reasonable number of wires;.
the necessity for a bobbin per wire being removed the large costly multiple-
bobbined machines are no longer necessary.
I can thus spin compound strands by laying wires individually of any section or
strands composed of wires of any section.
To put my invention into practice I combine a certain number of wires two three
four or more into strand and this is wound again on to the bobbins. The bobbins
are then placed in position on the "flyers" of the machine and the strand from each
is led to the lay plate in which there are at least as many perforations as the total
number of the wires in the strands being led thereto. The ends of the wires are
then put through the perforations and led to the dies in the usual way. On the
revolution of the machine the wires in the strands between the bobbins and the lay
plate are unlaid and pass through the holes in the lay plate separately just as if
coming off separate bobbins and are relaid or closed again on the opposite side of
the lay plate into a compound strand or into one course of a compound strand as
required.
Exemplifying the above which is capable of great expansion. in: detail for an
ordinary compound strand of nineteen wires four bobbins each containing three-ply
strand may be revolved as just described round a core of seven wires: here the
twelve external wires are laid with a four bobbin machine instead of as. would be
necessary under the existing system with a twelve-bobbin machine.
Similarly in a thirty seven-wire strand by the existing method six wires are spun
round one equal to seven. Then with a twelve bobbin machine twelve wires are
spun round seven equal to nineteen. Finally an eighteen-bobbin machine is
necessary to spin eighteen wires round nineteen equal to thirty seven in all whereas
by my system this strand can be spun and completely finished by a machine
carrying only six bobbins. To effect this for example 1 proceed to lay up six
lengths of strand of six wires as the first operation. These lengths are then put on
the bobbins one strand on each and the separate wires are treated at the lay plate
as above described. On the revolution of the machine the complete strand is formed
at once the wires being unlaid on one side and closed on the other side of the lay

plate as above described or dispensing altogether with the perforated lay plate
having first spun for example my six wire strand of triangular section instead of
cylindrical I may pass these side by side through the closing dies and a perfect
strand composed of segments of a circle results.
The system herein described is as will be understood capable of great variation
in detail but its essence consists as foreshadowed in the manufacturing of strands
with the use of fewer bobbins than there are separate wires in each separate course
of wires.

COMPLETE SPECIFICATION.
Improvements in or connected with Wire Rope Manufacture.
I, CHARLES JOHN BANKS of The Willows, Washington in the County of
Durham, Rope Works Manager do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:--
וי
This invention relates to improvements in or connected with wire rope manu
facture and consists in a novel method or process having for its object the elimination
of parts of machinery hitherto considered essential in this industry with a consequent
reduction in cost of manufacture both as regards labour and imaterial.
Hitherto in the manufacture of strands for ropes it has been found necessary to
employ a machine containing or capable of containing as many bobbins as there are
wires in the strand or in the annular courses of the strand; in other words cach
bobbin has hitherto carried one wire only.
.
Thus to compose a strand of nineteen wires by the existing system six wires
coming off six separatebobbins are first' spun round one as a core making seven wires
in all by a second operation a course of twelve wirestis then spin' round the seven
aforesaid 'making nineteen in all. The latter operation requires a twelve-bobbin
machine to spin the twelve wires and in like manner if strands of greater numbers
of wires are required so will a machine containing a' minber of bobbins corre-.
sponding to the greater numbers of wires he rendered necessary.
My invention consists. in a method or process by which with for example a'
six-bobbin machine I can spin a strand composed of any reasonable number of
wires the necessity for a bobbin per wire being removed the large costly!
multiple-bobbined machines' are no longer necessary,
I can thus spin compound strands by laying wires individually of any section"
or strands composed of wires of any section.
To put my invention into practice I combine a certain number of wires two
three four or more into strand and this is wound again onto the bobbins. The
bobbins are then placed in position on the "flyers" of the machine and the'
strand from each is led to the lay plate in which there are at least as many
perforations as the total number of the wires in the strands being led thereto..
The ends of the wires are then put through the perforations and led to the dies
in the usual way: On the revolution of the machine the 'wires in the strands
between the bobbins and the lay plate are unlaid and pass through the holes in
the lay plate separately just as if coming off separate bobbins and are relaid
or closed again on the opposite side of the lay plate into a compound strand
or into one annular course of a compound strand as required.

Exemplifying the above which is capable of great expansion in detail for an"
ordinary compound strand of nineteen wires four bobbins each containing three-
ply strand may be revolved as just described round a core of seven wires: here
the twelve external wires are laid with a four bobbin machine instead of as
would be necessary under the existing system with a twelve-bobbin machine.

page_text: Similarly in a thirty-seven-wire strand by the existing method six wires are
spun round one equal to seven. Then with a twelve bobbin machine twelve wires
are spun round seven equal to nineteen. Finally an eighteen-bobbin machine is
necessary to spin eighteen wires round nineteen equal to thirty seven in all
whereas by my system this strand can be spun and completely finished by a
machine carying only six bobbins. To effect this for example I proceed to lay
up six lengths of strand of six wires as the first operation. These lengths are
then put on the bobbins one strand on each and the separate wires are treated
at the lay plate as above described. On the revolution of the machine the
complete strand is formed at once the wires being unlaid on one side and closed
on the other side of the lay plate as above described or dispensing altogether
with the perforated lay plate having first spun for example my six wire strands
of triangular section instead of cylindrical I may pass these side by side
through the closing dies and a perfect strand composed of segments of a circle
results.
The system herein described is as will be understood obviously capable of great
variation in detail but its essence consists as foreshadowed in the manufacturing
of strands with the use of fewer bobbins than there are separate wires in each
separate course of wires.
Thus assuming all the wires in a given strand to be of the same gauge or
diameter, then a six-bobbin machine is by my system capable of composing in
a practical manner a strand containing 127 individual wires whereas by the
existing system of a bobbin per wire a thirty-six-bobbin machine would be
required to do this work.
Further the more bobbins are employed, the more remnants of wire must
obviously result, so that economy is effected in this respect also.
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. In wire rope manufacture by machinery the improved method or process
of composing or manufacturing strands of a greater number of individual wires
than there are separate bobbins in the machine substantially in the manner and
for the purposes herein set forth.
