stronger and more durable than heretofore.
In carrying my invention into effect, I construct the ropes with an inner wire-
core of copper, brass, iron or steel or other metal. This core may consist of one-
wire only, or it may be several wires twisted together, and on this the strands of
the rope are afterwards spun. Besides one core of copper or other wire running
up the centre of the rope, there may be similar cores formed to pass through the
centre of each individual strand of the rope.
The ends of the wire are twisted or fastened together before the strands are
finally fixed into an endless band.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Driving Ropes.
I, ROGER POMFRET of 79, and 81, Northgate, Blackburn, in the County of
Lancaster, Rope Manufacturer, 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 :-
The object of this invention is to prevent as much as possible the undue
attenuation of hempen, cotton, and similar driving ropes whilst in use, and at the
same time to render them stronger and more durable than hitherto.
In carrying my invention into effect, I construct the rope with an inner wire core-
of copper, brass, iron, steel or other metal. This core may consist of one wire only,
or it may be several wires twisted together, and on this the strands of the rope are
afterwards twisted or built. Besides the one core of copper or other wire running
up the centre of the rope, there may be several cores formed to pass through the
centre of each individual strand of the rope.
The ends of the wire core are twisted or fastened together before the strands are
finally spliced into an endless band.
In the accompanying drawings,
Fig. 1 is a view of a driving rope constructed in accordance with my invention.
A are the strands of the rope, which may be of any desired number, and twisted
as may be required. B is the inner wire core of copper, brass, iron, steel, or other
metal running preferably through the centre of the rope. This wire core may be
of any suitable strength or thickness, and of such flexibility as to readily permit
the rope to be used for driving purposes. Instead of being built on several wires.

page_text: twisted together as shewn in Fig. 1, the rope may have a single wire core C, as seen
in Fig. 2; or, each individual strand of the rope may be formed with an inner wire
core D, as represented in Fig. 3.
Some driving ropes have an inner core of hemp, cotton or the like as illustrated
at E in Fig. 4, or each separate strand of the rope is formed with an inner core of
the same material, but in any of these cases, my invention may be readily applied.
Previous to the ends of the rope being spliced, the ends of the wire core are
twisted or fastened together, so that when the rope is finally pieced, and is used
for driving purposes, there is very little giving way or slackening, whereby the
rope is not only more efficient as a driving medium, but its life is also considerably
prolonged.
Having now particularly described-and-ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
The improved construction of hempen, cotton, and similar driving ropes by
forming them with an inner core of one single wire or a number of twisted wires,
and either through the centre of the rope, or through each individual strand,
substantially as described and illustrated for the purpose set forth.
