IMPROVEMENTS IN THE MANUFACTURE OF FLAT ROPES
Year: 1885

page_text: I CHARLES JOHN BANKS of 25 Cecil Road, Seaforth Liverpool in the County of
Lancaster, Wire Rope Agent do hereby declare the nature of my said Invention for
IMPROVEMENTS IN THE MANUFACTURE OF FLAT ROPES," to be as follows:-
"8
Whereas in the modes hitherto employed in the manufacture of flat ropes it has
been found that in stitching or rivetting through the separate ropes, used to form,
when united, a flat rope, that the strands in the different component round ropes
become displaced resulting in an unevenness in the length of the same when united
by the said wire stitches or rivets, and thereby causing an unequal distribution of
the load or strain upon a flat rope made in this manner.
Now the object of my invention is to overcome this liability to displacement in
the strands of the component round ropes and to produce a flat rope which shall
be held firmly and compactly together by the binding wires in such a manner as to
secure evenness in length and uniform strength of the component round ropes
throughout the finished flat rope.
In order to effect this I take any number of round ropes required to be united
to form a flat rope these being alternately of right and left handed lay and placed
side by side and parallel to each other, and the binding wires or strands of wires
made to pass round over and under the outsides of such component round ropes so
as to lie in the hollows of the same between the strands, thereby forming a flat
rope of the desired compactness and strength.
The worming or binding the wires or strands of wires round the component
round ropes may be effected either by hand by passing the bobbins carrying the
lacing or binding wire over and under the alternate ropes from hand to hand as
required, or by equivalent suitable mechanical means.

the manufacture of Flat Ropes.
I CHARLES JOHN BANKS of 25 Cecil Road, Seaforth, Liverpool in the County
of Lancaster Wire Rope Agent, 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:-
Whereas in the modes hitherto employed in the manufacture of flat ropes, it has
been found that in stitching or rivetting through the separate ropes used to form
when united a flat rope, the strands in the different component round ropes become
displaced resulting in an unevenness in the length of the same when united, by the
said wire stitches or rivets, and thereby causing an unequal distribution of the
load or strain upon a flat rope made in this manner..,

Now the object of my Invention is to overcome this liability to displacement in
the strands of the component,round ropes, and to produce a flat rope' which shall
be held firmly and compactly together by the binding wires in such a manner as
to secure evenness in length and uniform, strength of the component round ropes
throughout the finished flat rope.
In order to effect this I take any number of round ropes required to be united
to form a flat rope, these being alternately of right and left handed lay and placed
side by side and parallel to each other, and the binding wires or strands of wires
made to pass round over and under the outsides of such component round ropes.so
as to lie in the hollows of the same. between the strands, thereby forming a flat
rope of the desired compactness and strength.
The worming or binding of the wires or strands of wires round the component
round ropes may be effected either by hand by passing the bobbina.carrying the
lacing or binding wire over and under the alternate ropes from hand to hand as
required, or by equivalent suitable mechanical means.
In order that my Invention may be fully understood :I will describe it.more
particularly by the aid of the accompanying drawings in which are represented
two methods of manufacturing flat ropes.
DESCRIPTION OF THE 'DRAWINGS.
Figures 1. 2. 3. show six four-stranded. ropes.3 right hand lay and 3 left hand
lay arranged in couples for the purposes of explanation as hereinafter given.
Fig. 4 shows four ropes each rope being four stranded as an example of an
alternative mode of producing a flat rope.
Fig. 5 shows a completed flat rope composed of four three stranded component
.35
ropes.
One method of binding the ropes as shewn by means of figures 1. 2 and 3 I will
proceed to describe. Each of the ropes has four binding wires A. B. C. D.
and 1. 2. 3. 4. one to each strand. These wires are passed alternately from left
to right (as shown by A. B. C. D. Fig. 1) and from right to left (as shewn by
1. 2. 3. 4 Fig. 1) each wire being passed over its own rope and under the adjoining
rope thereby binding each two ropes together: taking the upper wires and binding
or worming them as described, that is A and 1. then B. and 2, and so on to the
_ end of the rope the required length of ropes may be bound together.

page_text: In order to bind four ropes together for instance the sets shewn in Figures 1.
and 2, the process will now be similar to that above described except that the
ropes shewn in figures 1 and 2 will be made to exchange their respective wires on
their adjoining sides, thus fig. 2 will use wire A from fig. 1 and transfer its wire
(fig. 2 A) to fig. 1, which is effected by crossing the said wires. By continuing
in this manner to transfer or interweave alternately the two sets of lettered
wires A. B. C. D and numbered wires 1. 2. 3. 4 of fig. 1 and 2 the binding together
will be carried out.
In order to bind six ropes taking fig. 2 as the centre couple of ropes, fig. 2 will
exchange a wire on either side with Fig. 1 and Fig. 3 in a similar way to that
described in the case of binding four ropes together.
The above described method is given as an illustration of one mode of inter-
weaving or lacing wires or strands of wires round the outsides of individual ropes
in order to bind each rope to the adjoining one.
And I wish it to be understood that I do not confine myself to ropes of four
strands each this form being merely used in Figures 1. 2. 3. for convenience of
explanation of the principle, which principle is identical however many strands
the individual or component ropes may be composed of.
Also I need not always
employ as many binding wires as there are strands in the component ropes, for
example I may use component ropes of six strands each and bind them with one,
two, three, four five or six bindings to each component rope as expedient. Also
I may bind the component ropes together with single wires (as shewn in the
drawings) strands of wires, fibrous material, wires covered with fibrous material, or
fibrous material covered with wire. And further I do not confine myself to the
mode of passing the bindings directly from rope to rope.
I will now describe another method to illustrate this feature of my Invention.
In Figure 4 four ropes are represented at F and a binding wire at E, in this
instance the wire is given a full turn round the first rope, then it is passed on to
the next rope, round which a similar turn is given, and so on through the set; the
wire will then be led backwards and forwards in twists round the set of ropes as
required to bind them into a flat rope.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The mode or method of binding together two or more parallel round ropes by
means of binding wires such wires being caused to pass over the outsides of the
said round ropes so as to lie in the hollows between the strands of the same instead
of stitching or rivetting them through the centres of the said ropes substantially as
hereinbefore described.
