page_text: We, ARTHUR LATCH, of Biddick Hall, South Shields, Durham, Gentleman and
TELFORD CLARENCE BATCHELOR, of 8 Barons Court Road, West Kensington,
Middlesex, Engineer do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :—
According to the first part of our invention, we take a wire or wires of any desired
sectional shape, other than round, and lay or twist other wires around such sectional
wire or wires to form a strand.
The internal wire or wires are preferably of oval, oblong, or of triangular shape or
the internal wires are composed of two or more wires to constitute such a shape, so
that when the outer wires are laid or twisted thereon, an oval strand, an oblong strand,
or a triangular sectional shaped strand is produced.
We then take the necessary number of such constructed strands and arrange them
to conform to the desired shape of rope to be made.
According to the second part of our invention, we take two or more ordinary round
wires, and place them contiguous to each other; and we lay or twist wires thereon;
so that the two or more internal wires are enclosed in side-by-side order and retained
strand of oval, oblong, or
in that position within said wire covering to constitute
triangular shape in cross section.
According to the third part of our invention we take two or more strands of any
shape of wire or wires, and arrange them contiguous to each other and we cover the
combined number of strands with other wires as a sheath to constitute a rope or band
of oval, oblong, or triangular shape in cross section.
Two or several of such combination ropes or bands may be twisted together or they
may be laid around a core, if a core be used, whereby the inner surface of each
combined rope or band accommodates itself to that portion of the core with which it
is in contact, the outer surface of the cover of each combined rope or band assuming a
curve or segment of a circle according to the diameter of the rope in its completed
form.
It is not compulsory to arrange a series of the combination strands, ropes or bands

page_text: around a core, because each combination forms a rope or band in itself and they may
therefore he employed singly for the purpose in which wire ropes are used.
Some examples of our arrangements of wires, and of strands, and also combinations,
before described are shown in the annexed drawings, in which at Figure 1 we show a
strand composed of a centre wire A of oval, or oblong shape, encircled by other
wires B, B, laid thereon, the outer wires B, B, conforming to the oval or oblong
shape of the central wire A.
cf
At Figure 2 we represent two sections of wires A, A, of special shape and so placed
that they touch and form an oblong or oval internal but such interior may be composed
any number of separate wires which when in touch would form a shape other than
a round, upon which other or ordinary wires could be laid or twisted to constitute a
strand, the contour of such strand bring the same as that of the combined internal
wires.
Figure 3 shows another arrangement of two specially shaped wires A, A, to
constitute an oblong, an oval, or other equivalent shaped interior and with ordinary
wires B, B, laid or twisted upon them to constitute a strand.
According to Figure 4 we show another or modified arrangement of three
wires A, A, A, of a shape serving as internal wires and upon which other or ordinary
wires are laid or twisted and constituting a strand of an oblong or oval character
similar to those indicated by Figures 1, 2 and 3.
These shaped internal wires A, A, are subject to many modifications of shape, as
well as to the numbers of such or of equivalent wires to constitute an oblong, an oval,
or like shape of strand when the outer wires B, B, are laid or twisted upon them.
At Figure 5 we represent the central wire A of triangular shape the outer wires B, B,
laid thereon maintaining the triangular formation and at Figure 6 we show the
internal part composed of three distinct, yet similarly shaped wires A, A, A, and
constituting a triangle, the outer wires B, B, being laid or twisted thereon.
Figure 7 is a section of a rope composed of six strands of the example shown at
Figure 1 and Figure 8 is a similar section of rope composed of six strands of the
example shown at Figure 5.
At Figure 9 we show an example with two round wires and at Figure 10 three
round wires A, A, arranged side by side and surrounded by outer wires B, B, as a
covering (these wires B, B, may be either single wires as indicated, or as strands of
laid or twisted wires).
Figures 11 and 12 are sectional plan and elevation respectively of two ordinary
strands A, A, which may consist of any required number of wires enclosed by an
outer covering of wire B. B, laid or twisted thereon.
Either of the combinations heretofore described may form a rope in itself which
may be used as an ordinary rope.
Figures 13 and 14 are similar views of a rope in which three strands or ropes A, A, A,
are enclosed in outer wires B. B, as a covering, two of such combination being
twisted round a core C to constitute a rope.
Figures 15 and 16 represent sectional plan and elevation of a rope composed of six
of such combination ropes or bands A, B, twisted round a central core C and con-
stituting a rope.
We have shown the six combination bands or ropes, each having two ordinary
strands within the outer casing, but they may be varied .e. some of such combina-
tion may have two, and some three internal strands A, A, A, or there may be more
than three strands A, A, A, enclosed by an outer casing B of wires to constitute a rope
of our improved construction, and instead of all the interior strands, ropes, or wires
of the several ropes or bands being of the same guage they may be varied to suit
circumstances.
Figure 17 respresents sectional plan of a rope formed of two combination bands or
ropes twisted together without a core, in which case the interior strands A, A, are not
of uniform size but of such that the exterior of the band or rope forms the segment of
a circle, when twisted together with a portion forming the centre and abutting
against each other.

page_text: Figure 18 represents sectional plan of a rope composed of six triangular shaped
combination strands, bands, or ropes, each having three interior strands or ropes A, A, A,
enclosed by the covering wires B.
The core may be of any material wire, hemp or the like and the spaces E, E, may
if desired, be filled with hemp or other suitable material.
The sheathing wires B, B, may be of any sectional form.
In forming the strands, of which a rope according to our invention may be made,
we sometimes give a twist to the strands of such a pitch as will be taken up in the
lay of the rope in closing together, so that one of the flattened surfaces of each strand
of which the rope is composed inay continue on the outside of the rope its entire
length.
The twist in the strand is formed by giving a spiral formation to the interior wire
or wires to which the covering wires when laid on conform.
We have shown the various strands, bands, or ropes, as having the outer
covering B, B, composed of single wires but they may be either single wires as indi-
cated or as strands of laid or twisted wire.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim
1. The employment of a wire or wires of oval, oblong, triangular, or equivalent
shape, other than round in cross section, as a centre, on which other wires of any
shape may be laid or twisted to form a strand corresponding in shape to that of the
central wire, or combined wires, as described and substantially as shown in the
annexed drawings, Figures 1, 2, 3, 4, 5 and 6.
2. The employment of two ordinary round wires (touching) as internal wires and
constituting when other wires are laid or twisted thereon, a strand of oval or oblong
shape as described and substantially as shown in the annexed drawings Figure 9.
3. The employment of three or more ordinary round wires so arranged as to
constitute when other wires are laid or twisted thereon, a strand of a shape in cross
section other than round, such as an oval, an oblong, a triangular or equivalent shape
as described and substantially as shown at Figure 10 in the annexed drawings.
4. The combination of strands composed of any shape of wires, so arranged that
when placed side by side and have outer wires laid or twisted thereon, a rope is
produced of a shape other than round as described and substantially as shown at
Figures 11, 12, 13, 15, 17 and 18 of the annexed drawings.
5. The combination of two or more oval, oblong, triangular, or other shapes of
ropes or strands other than round, laid or twisted among themselves to constitute a
rope as described and substantially as shown at Figures 7 and 8 of the drawings.
6. The formation of a rope the strands of which are built up or composed of wire
constituting a strand as hereinbefore described and being of shape other than round
in cross section which when laid or twisted into the rope presents a flattened surface
on the outside of the rope, the same flattened surface being maintained on the outside
for its entire length as described and as shown in the drawing annexed.
