IMPROVEMENTS IN THE MANU- FACTURE OF WIRE ROPE
Year: 1876

page_text: LETTERS PATENT to Robert Stirling Newall, of Ferndene, Gateshead, in the
County of Durham, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF WIRE ROPE."
ealed the 5th January 1877, and dated the 6th November 1876
PROVISIONAL SPECIFICATION left by the said Robert Stirling Newall at the
Office of the Commissioners of Patents on the 6th November 1876.
ROBERT STIRLING NEWALL, of Ferndene, Gateshead, in the County of Durham
"IMPROVEMENTS IN THE MANUFACTURE OF WIRE ROPE."
It is the practice in making wire rope to lay a number of wires round a core to
make 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 7th 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, the
wires forming the strands being all laid in the same direction, that is, in making a six
strand rope, the wires forming each strand are laid to the left hand, and the strands
are all laid to the right hand generally, but sometimes vice versa. The consequence
of this is, that where two strands touch each other, when laid into a rope, the wires
cross or lie in opposite directions, and by the working of the rope the wires cut into
each other, and the rope does not last so long as it would do if the wires lay in the
same direction where they touch each other."
The object of my Invention is to remedy this defect, and I do so by laying the
wires forming each alternate strand to the left hand, and the others to the right,
and combine them into a rope in the usual manner by laying all the strands to the
right hand, or all to the left, as may be desired. I prefer to make ropes of an even
number, say 4, 6, or 8 strands.
In adapting this Invention to the manufacture of flat ropes I make as above,
say four right-hand ropes and four left-band, each containing four strands, and I
combine these right and left-hand ropes by placing them alternately, as is the
practice at present, and sewing them together by interlacing wires, or what I much
prefer, by thin iron hoops, which prevents the wires cutting into each other, as is
the case at present.
For the purpose of attaching a load to the end of a rope, I use a conical socket

page_text: slightly tapered inside, into which I pass the end of the rope, and then drive in a
circular wedge so as to prevent the end of the rope being drawn out of the socket,
to which the load is afterwards attached.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Robert Stirling Newall in the Great Seal Patent Office on the
4th May 1877.

"IMPROVEMENTS IN THE MANUFACTURE OF WIRE ROPE."
It is the practice in making wire rope to lay a number of wires round a core to
make 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 7th 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, the
wires forming the strands being all laid in the same direction, that is, in making a
six strand rope, the wires forming each strand are laid to the left hand, and the
strands are all laid to the right hand generally, but sometimes vice versa. The
consequence of this is that where two strands touch each other when laid into a
rope, the wires cross or lie in opposite directions, and by the working of the rope,
the wires cut into each other, and the rope does not last so long as it would do if
the wires lay in the same direction where they touch each other.
The object of my Invention is to remedy this defect, and I do so by laying the
wires forming each alternate strand to the left hand, and the others to the right,
and combine them into a rope in the usual manner by laying all the strands to the
riglit hand, or all to the left, as may be desired. I prefer to make ropes of an
even number, say, 4, 6, or 8 strands.
In adapting this Invention to the manufacture of flat ropes, I make as above, say
four right-hand ropes and four left-hand, each containing four strands, and I combine
these right and left-hand ropes by placing them alternately, as is the practice at
present, and sewing them together by interlacing wires, or what I much prefer, by
thin iron hoops, which prevent the wires cutting into each other as is the case at
present.
For the purpose of attaching a load to the end of a rope, I use a conical socket
slightly tapered inside, into which I pass the end of the rope, and then drive in a
circular wedge so as to prevent the end of the rope being drawn out of the socket,
to which the load is afterwards attached.
This Invention is illustrated by the Drawings annexed.
What I claim is,―
First. The manufacture of wire ropes with the strands laid alternately to the right
and left hand, substantially as described.
Second. The means of attaching the rope to the load, substantially as described.
In witness whereof, I, the said Robert Stirling Newall, have hereunto set my
hand and seal, this First day of May, in the year of our Lord One thousand
eight hundred and seventy-seven.
