Improvements in Wire Ropes.
I EDWARD CLARENCE, BEDDOE 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 hemp 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 hitherto manufactured, while being
likewise capable of supporting a much greater breaking strain and being less liable
to snapping.
In carrying my invention into practice I form a rope preferably of six strands
each of which is provided with a large centre wire surrounded by a circular row of
eight smaller wires and a layer formed of eight even surface dovetailed tapered wires
twisted left handed, the six strands being twisted left handed around a hempen
core. Each strand containing seventeen wires, the rope will consist of one hundred
and two wires.

Improvements in Wire Ropes.
I, 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, hemp and other ropes for winding
hauling and generally for mining and other purposes.
The object of my improvements is to combine hemp with wire in such a manner
as to form a rope which will be much more flexible and produce much less friction
than the wire ropes hitherto used while being at the same time capable of
supporting a much greater breaking strain and being less liable to snapping.
In carrying my invention into practice I arrange around a hempen core a number
of strands consisting each of a central wire surrounded by a number of smaller
wires the whole of which is twisted together in one direction, and of an outer
covering composed of a number of wires of dove-tail section fitting one another and
twisted in the reverse direction to the former and in the same direction as the
whole rope is finally twisted. In some cases I dispense with the number of smaller
wires above mentioned.
In the accompanying drawings in which like letters of reference indicate corre-
sponding parts-
Fig. 1 is a perspective view illustrating my improved construction of rope,
Fig. 2 being a similar view showing a simplified arrangement of the same.
The rope consists of a hempen core D surrounded by six circular strands, all
twisted together in one direction i.e. from right to left or left to right and at a
suitable angle or pitch.

page_text: Each strand is composed of a central wire A surrounded by eight smaller wires c
twisted in an opposite direction to the rope that is to say from left to right or from
right to left respectively and at the same angle or pitch. Around this strand core
are placed eight dove tailed wires of the shape clearly shown in the figure and
fitting close together, these wires being twisted in the opposite direction to the
strand core and in the same direction as the rope that is to say from right to left
or from left to right respectively and at the same angle or pitch.
In the, construction of rope shewn in Fig. 2 I dispense with the eight small wires
'aforesaid and substitute therefor a larger central wire A surrounded as before by
eight dove tailed wires B. may further construct the above ropes with other
than circular wires in the strand, core, but they are always surrounded with a row
of dove tailed wires which is together with the mode of twisting the characteristic
feature of my invention.
Having now fully 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
1) The improved construction of rope consisting of a number of strands
arranged around a hempen core and twisted in one direction at a suitable angle
or pitch, the said strands being formed of a row of dove-tailed wires twisted in
the same direction as the strands aforesaid and surrounding a row of small wires
twisted around a central wire in an opposite direction to the former, but at the
same angle or pitch substantially as herein described and shown in Fig. 1 of the
accompanying drawings.
2) The simplified construction of rope shown in Fig. 2 consisting of a number
of strands arranged around a hempen core and composed of an inner wire surrounded
by a row of dove tailed wires of the kind above claimed, twisted in the same direction
and at the same angle or pitch as the rope rope substantially as herein described.
