Improvements in Ropes or Cabies.
Year: 1894

page_text: Date of Application, 7th Aug., 1894
Complete Specification Left, 7th May, 1995-Accepted, 22nd June, 1895
We, EDWARD SAMUEL BOND, and GEORGE HENRY COOPER, of the Firm of
Bond & Cooper, of Crown Works, Booth Street, Handsworth, in the County of
Stafford, Machinists, do hereby declare the nature of our said invention to be as
follows:-
Our invention has for its object improvements in ropes and cables whether of
wire, hemp or other materials by which we provide a flexible core for taking up
any stretch in the rope. This core retains its flexibility and forms a foundation
upon which ropes or cables of any size or section can be built. The core being
hollow has the advantages of a hollow rope or cable with considerably less cost in
manufacture.
In carrying our invention into effect we form a coii of wire preferable of steel
which we make with the coils sufficiently close together to practically form a tube
upon which the strands of wire are twisted to form the rope or cable or around
which the hemp, hair or other material of which the rope is to be formed is
worked. Although we prefer a coil of close pitch yet we may vary the pitch and
guage and the class of metal to any extent. We may by means of suitable
mechanism form the core of any required section such as round, square, oval,
hexagon or other section and the diameter or size may vary to any extent.

Improvements in Ropes or Cabies.
We, EDWARD SAMUEL BOND, and GEORGE HENRY COOPER, of the Firm of
Bond & Cooper, of Crown Works, Booth Street, Handsworth, in the County of
Stafford Machinists do hereby declare the nature of our said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
Our invention has for its object improvements in ropes or cables by which we
provide a core or cores for such ropes or cables which while being flexible forms a
strong hollow core which assists the rope or cable to withstand a considerable
amount of pressure without losing its shape while the hollow core is particularly
useful for containing wires and cables for the supply of electricity for various
purposes as the cable or rope is capable of being readily bent round corners and
in any required direction without any jointing while it forms a particularly strong
& secure casing to the inner supply wires. The cure may also be formed to contain
and convey liquids in a similar manner.
In order that our invention may be clearly understood and more easily carried
into practise we have appended hereunto a sheet of drawings upon which we have
fully illustrated the nature of our said improvements.

Figure 2, is a section through Figure 1.
Figure 3, is a section through a single coil cable casing for electric supply
wires.
Figure 4, is a similar view to Figure 1 but showing a modification in formation
of cable.
Figure 5, is a cross section similar to Figure 2 but illustrating the application of
the rope for casing of electric cables.
Figure 6, is a longitudinal section showing a suitable means for connecting the
cable lengths together when used as casings for electric cables.
In carrying our invention into effect we form a coil of wire A preferably of steel
which is formed with the coils sufficiently close together to practically form a
solid tube although we do not confine ourselves to a coil so close. Around this
coil A the strands or series of strands B are twisted as shown so as to form a casing
which with the aid of the inner coil A has great resistance or crushing strain to
pressure such as the tramway gripper which cannot thus press the rope out of
shape. The coil A may be of any suitable shape in section such as round, as shown,
square, hexagonal or other section and the diameter or size may vary to any
extent. The wire of which the coil is formed may be of square round or other
suitable section and two or more of such coils one within the other as shown
by A2, A3, Figure 4 may be used while in such cases one coil may be cuiled to the
right while the other is coiled to the left.
In cases where these ropes are used as cables for conveying electricity, separate
coils A may be placed in each of the surrounding groups of wires by which means
one coil may contain one main supply and three four five or six secondary or
branch supplies as shown by Figure 5. It will be seen that such a cable while
having great compressive resistance, at the same time lends itself to be readily bent
around angles and in any direction with little or no labor. The combination of
the closely coiled internal core with the external strands twisted around same
forms a waterproof casing which is particularly applicable for the protection of
electric mains. The coils A may contain Hexible tubing of any material by which
means liquids can be readily conveyed. In cables having a great compressive
strain the internal continuous coiled spring A forms a hollow core which forms a
great resistance to the pressure of the grippers thus ensuring the cable retaining
its original sectional shape for which purpose we prefer to make the coils of
proportionately large guage wire. In the case of cables which form a casing for
electric supply wires where little or no tension is required the strands around
the coil may be of small guage wire as shown by Figure 5. It will be readily
seen that the coils A¹ may be branched off from the main trunk coil A when so
needed.
The various lengths of ropes may be connected together in various ways as for
instance as shown by Figure 6 where in case of using them for electric cables
the ends of the rope are secured to the collars C which may be screwed on
their exterior surface for the two way screwed collar C which connects the two
together.
Having now particularly described and ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is :-
1st. The improvements in wire ropes and cables for the purpose of withstanding
a compressive force substantially as herein set forth and shown upon the
accompanying drawings.
2nd. The improvements in wire ropes and cables by which a flexible non-com-
pressive and waterproof casing is formed for electric supply wires substantially
as herein set forth and shown upon the accompanying drawings.
3rd. The improvements in wire ropes consisting of a series of hollow cores A A¹
substantially as and for the purpose herein set forth & shown.

inner flexible tube substantially as and for the purpose herein set forth.
