PROVISIONAL SPECIFICATION.
Improved Formation or Construction of Wire Ropes.
I, ABBOTT GODFREY LAKER, of 132 Courthill Road, Lewisham, Kent,
Gentleman, do hereby declare the nature of this invention, to be as follows:-
In carrying out my invention I construct strands of my wire rope by laying or
placing side by side two or more round wires and cover them by laying or twisting
other round wires over them in the direction in which I intend to lay, twist, or
place the said strands into the finished rope, thus making a form of strand the
cross section of which is larger if measured in one direction than it is in the other,
and I then take two or more of such strands and I lay or twist them together in
the same direction as the direction of the outer covering of wires composing the
strands, and round a central corc.
I am aware that strands having varying diameters in cross section have been
made before, and that wire ropes have been constructed having the wires in the
strands and the strands in the rope in the same direction, but by my method of
making the rope as described above I obtain a very flexible strand which bends
very easily and which has on its broader diameter a very large surface to resist
wear, and by placing the wires at a suitable pitch or angle in the strands and in
the same direction as the strands are laid, placed, or twisted into the rope, the
wear comes along the length or approximately so of the individual wires, in a way
giving great advantages under certain conditions of working.
By laying, placing, or twisting the wires in the strands in the same direction as
the lay or twist of the strands in the rope I mean that they shall each be laid,
placed, or twisted from right to left, or from left to right as the
case may be.
The core for the finished rope may be composed of hemp, or wire, or of other
suitable material.
I sometimes make the strands of a combination of strands of round wires and
of single round wires, or I build up a strand composed partly of round wires and
partly of wires of a section other than round, or I compose the strands entirely of
wires of a section other than round, or 1 may make the centre of my strands of
hemp or other suitable soft material, but in any case I make the strand of which
the rope is composed of such a shape that in cross section one diameter of such
strand is less than the other, and I place the outer wires of which the individual
strands are composed in the same direction as the direction in which the strands
are laid, placed, or twisted into the rope.

COMPLETE SPECIFICATION.
Improved Formation or Construction of Wire Ropes.
I, ABBOTT GODFREY LAKER, of the Patent Wire Rope Works, Collingdon
Road, Cardiff, Gentleman, 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 :---
In carrying out my invention, I construct strands of my wire rope by laying or
placing side by side two or more round wires A, A, and cover them by laying or

page_text: twisting other round wires B, B, over them, as at Figure 1, in the direction in
which I intend to lay, twist, or place the said strands into the finished rope, thus
making a form of strand, the cross section of which is larger if measured in one
direction than it is in the other, and I then take two or more of such strands and
I lay or twist them together in the same direction as the direction of the outer
covering of wires composing the strands and round a central core C.
I am aware that strands having varying diameters in cross section have been
made before, as in Latch and Batchelor's Patent No. 12285 of 1888, and that
wire ropes have been constructed having the wires in the strands and the strands
in the rope in the same direction, as in Lang's Patent No. 178 of 1879, but by
my method of making the rope as described above, I obtain very flexible strand,
which bends very easily, and which has on its broader diameter a very large surface
to resist wear.
By placing the wires at a suitable pitch or angle in the strands
and in the same direction as the strands are laid, placed, or twisted into the rope,
the wear comes along the length or approximately so of the individual wires in a
way giving great advantages under certain conditions of working. By laying,
placing, or twisting the wires in the strands in the same direction as the lay or
twist of the strands in the rope, I mean that they shall each be laid, placed, or
twisted from right to left, or from left to right, as the case may be.
The core for the finished rope may be composed of hemp, or wire, or of other
suitable material.
I sometimes make the strands of a combination of strands of round wires and
of single round wires, as at Figures 4 and 6, or I build up a strand composed
partly of round wires, and partly of wires of a section other than round, as at
Figure 2, and Figure 3, or 1 compose the strands entirely of wires of a section
other than round, as at Figure 5, or 1 may make the centre of my strands of hemp,
or other suitable soft material, but in any case, I make the strand of which the
rope is composed of such a shape that in cross section one diameter of such strand
is less than the other, and I place the outer wires of which the individual strands
are composed in the same direction as the direction in which the strands are laid,
place, or twisted into the rope.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The formation or construction of wire ropes in which the wires composing the
strands are laid, placed, or twisted in the same direction as the covering wires,
each strand being of a shape other than round, and having one diameter of the cross
section greater than that of the other diameter, as hereinbefore described and
substantially as shown by the annexed drawings.
2. The formation or construction of wire ropes in which the strands are com-
posed of a core of a shape other than round from the combination of ordinary shape
wires, or of special shaped wires, these being covered by wires of a shape other
than round, and laid, placed, or twisted on the core in the same direction as that
of the core, as described and substantially as shown at Figure 5 of the annexed
drawings.
3. The formation of strands for wire ropes from a combination of ordinary round
wires as a core and of ordinary round strands as a covering thereto as described
with reference to Figure 6 of the annexed drawings the outer wires of the strands
and the strands of the rope being laid or twisted in the same direction as set
forth.
