IMPROVEMENTS IN WIRE ROPE & IN MACHINERY FOR MAKING SUCH ROPE
Year: 1879

page_text: LETTERS PATENT to Robert Stirling Newall, of Ferndene, Gateshead, in the
County of Durham, for the Invention of "IMPROVEMENTS IN WIRE ROPE &
IN MACHINERY FOR MAKING SUCH ROPE."
Scaled the 17th June 1879, and dated the 7th January 1879.
PROVISIONAL SPECIFICATION left by the said Robert Stirling Newall at
the Office of the Commissioners of Patents on the 7th January 1879.
ROBERT STIRLING NEWALL, of Ferndene, Gateshead, in the County of Durham.
"IMPROVEMENTS IN WIRE ROPE & IN MACHINERY FOR MAKING SUCH ROPE."
It is the practice in making wire rope to lay a number of wires round a core to
form a strand, and a number of these strands round a core to form a rope, and the
directions given in the Specification of my Patent of 7 August 1840, No. 8594,
have almost universally been followed in carrying out this important manufacture.
I there recommend that the strands should have double the lay of the rope, and in
carrying out the Invention the rope has been made by two operations, first, laying
the wires into the strand, and then laying the strands into a rope.
My present improvement in wire rope consists in laying the wires into a rope
composed of two or more strands, but without laying the wires into strands by
giving them a rotatory motion as usual, and thus combining them into a rope.
For this purpose I use a machine having two or more strand frames, each capable
of holding the requisite number of bobbins for carrying the separato wires, and I
cause each strand frame to rotate once on its axis, whilst the machine makes ono
revolution in laying the wires into a rope, so that there is no (what is commonly
called) twist put into each strand.
I prefer this plan to putting the wires required to form one strand on to one
bobbin, as in that case they might not be equally strained, which is of importance
and casily accomplished where the wires are cach on separate bobbins.

"IMPROVEMENTS IN WIRE ROPE AND IN MACHINERY FOR MAKING SUCH ROPE."
My Invention of "Improvements in Wire Rope and in Machinery for Making
such Rope" consists in the mode of manufacture and the machinery hereinafter
described.
It is the practice in making wire rope to lay a number of wires round a core to
form a strand, and a number of these strands round a core to form a rope, and the
directions given in the Specification of my Patent of Soventh August One thousand
eight hundred and forty, No. 8594, have almost universally been followed in
carrying out this important manufacture. I there recommend that the strands
should have double the lay of the rope, and in carrying out the Invention, the rope
has been made by two operations, first, laying the wires into a strand, and then
laying the strands into a rope.
My present improvement in wire rope consists in laying the wires into a rope
composed of two or more strands, but without laying the wires into strands by
giving them a rotatory motion as usual, and then combining them into a rope.
For this purpose I use a machine having two or more strand frames, each capable
of holding the requisite number of bobbins for carrying the separate wires, and I
cause each strand frame to rotate once on its axis whilst the machine makes one
revolution in laying the wires into a rope, so that there is no (what is commonly
called) twist put into each strand.
I prefer this plan to putting the wires required to form one strand on to one
bobbin, as in that case they might not be equally strained, which is of importance
and easily accomplished where the wires are each on separate bobbins.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, I hereby declare that what
I claim as of my Invention is, the mode described of manufacturing wire rope
from wires, without previously laying the wires into strands and the machine, for
the purpose herein beforo referred to.
In witness whereof, I, the said Robert Stirling Newall, have hereunto set
my hand and scal, the Third day of July, in the year of our Lord One
thousand eight hundred and seventy nine.
