PROVISIONAL SPECIFICATION.
Improvements in Wire Ropes.
I EDWARD CLARENCE BEDDOE of 5 London Street Newport Monmouthshire
Consulting Engineer do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to improvements in wire and other ropes for winding
hauling and other mining purposes and has for its object to combine hemp with
wire in such a manner as to form a rope which will be much more flexible and
operate with much less friction than the ropes hitherte manufactured while being
likewise capable of supporting a much greater breaking strain and being less liable
to snapping. In carrying my invention into practice form a rope of a number of
strands preferably six containing about fifty five wires, each strand containing
nine wires arranged around a hempen core coiled around a centre wire of the same
gauge as the centre wire contained in each strand which thus consists of eight wires
surrounding a centre wire as above mentioned.
In some cases I use one hundred and thirty nine wires for the six strands which
are formed of two circular rows surrounding the centre wire, the outer row con-
taining fourteen wires which are somewhat thicker than the inner row which
contains only (8) eight wires: the strands are arranged as above around a mixed
hemp and wire core.
The above mentioned rope is twisted left handed.

Ímprovements in Wire Ropes.
1 EDWARD CLARENCE BEDDOE of 36 Devon Place (late of 5. London Street)
Newport Monmouthshire 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:―
My invention relates to improvements in wire ropes for winding, hauling and
other mining and general purposes and has for its object to combine hemp with
wire in such a manner as to form a rope which will be highly flexible and operate
with much less friction than the wire ropes hitherto manufactured while being
likewise capable of supporting a much greater breaking strain-and being less
liable to snapping.
In the accompanying drawings in which like letters of reference indicate corre-
sponding parts,
Figs. to 11 shew perspective views illustrating various forms of ropes con-
structed according to my invention.
Referring to Fig. 1 my improved rope consists of a core D of hemp arranged
around a central wire C and surrounded by six strands formed of a stout central
wire A. enclosed within eight smaller cylindrical wires B which are twisted at a
suitable angle or pitch in the same direction as the finished rope will be finally
twisted.

page_text: Figs. 2, 3, 4, 5 and 10 shew a similar construction of rope in which the eight
smaller wires B. have a different sectional shape.
In the arrangements shewn in Figs. 6, 7, 8 and 11 ! substitute for the central
stout wire A aforesaid an inner strand consisting of a central wire surrounded by
eight thin wires the rope being otherwise constructed as above described with
reference to Figs. 1, 2, 3, 4, 5 and 10.
Fig. 9 shews a construction of rope in which the wires of the inner strand afore-
said are twisted in one direction while the wires Bare twisted in the reverse
direction which is the same as that in which the six main strands will be finally
twisted to form the rope the angular pitch remaining the same in both cases.
By the improved construction of rope above described the wear and tear will be
equally distributed over each separate wire throughout the same.
Having now fully 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.) A rope formed of a hempen core enclosing a central wire and surrounded by
a number of strands consisting of a central stout wire enveloped in a number of
smaller wires of circular elliptical, trapezoidal or other sectional shape, these
smaller wires being twisted in the same direction as the strands are finally twisted
to form the rope and at the same angle and pitch substantially as herein described
and shewn in Figs. 1, 2, 3, 4, 5 and 10 of the accompanying drawings.
2.) A rope formed of a hempen core enclosing a central wire and surrounded by
a number of strands consisting of an inner strand composed of a central wire
enveloped in a number of thin circular wires which are surrounded by a number of
wires of circular elliptical trapezoidal or other sectional shape the latter wires
being twisted in the same direction as the strands are finally twisted to form the
rope and at the same angle or pitch substantially as herein described and shewn in
Figs. 6. 78 and 11 of the accompanying drawings.
3.) A rope constructed as set forth in Claim 2 in which the surrounding wires
in the inner strand are twisted in a reverse direction to that in which the outer
and enveloping wires of the strands composing the rope are twisted but at the
same angle or pitch substantially as herein described and shewn in Fig. 9 of the
drawings.
