the Commissioners of Patents, with his Petition, on the 2nd December
1858.
I, JOSEPH ROGERS, of No. 9, Queen Square, Bartholomew Close, in the
City of London, Rope Maker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF ROPES, CABLES, CORDS,
AND LINES," to be as follows:-
The object of my Invention is to produce ropes, cables, cords, and lines of
every description, applicable to all purposes for which such are or may be
used, of great strength, lightness, and durability, particularly for electrical,
nautical, mechanical, mining, and agricultural purposes and I accomplish
this object by laying together longitudinally plaited or braided bands or twisted
cords or lines of hemp, flax, jute, cotton, silk, or some other fibrous material,
either spun, laid, plaited, or braided, according to the particular purpose to
which they are to be applied.
For electrical purposes, I cover a core or cores of wires, spirally twisted or
laid straight, either insulated or not, with a sufficient number of plaited or
braided bands or spiral cords, made of either of the above materials laid
longitudinally, so as to completely encircle the wire or wires, and I then
form the whole into a rope or cable, and bind it tightly together by hitching.
serving, whipping, or plaiting over with wire, thread, cotton, silk, or other
material suitable for the purpose. These longitudinal bands are then to be
saturated with the mixture or composition hereafter described.
D

page_text: The process of laying on a coating of bands or cords, as above described,
may be repeated any number of times that may be required to increase the
size and strength of the rope. or cable, each distinct coating or layer being
hitched, served, whipped, or plaited as before described, and also saturated
with the composition hereafter described.
The composition or waterproofing material before mentioned consists of a
mixture of boiled oil, resin, patent dryers, tallow, and pitch, tar, or dissolved
india-rubber, or some of them, thoroughly mixed, and boiled together. This
material may be applied either in a hot or cold state. The rope or cable is
then to be dried, and will be fit for use. The above composition, when
properly made and applied, will preserve and strengthen the rope or, cable,
and resist the passage of water to the enclosed wires.
When a rope or cable made on the principle of my Invention is required
for mining, nautical, or agricultural purposes, it may be manufactured in the
same manner as above described, first forming a core by laying together a
number of yarns or threads, with or without wire, and slightly twisted.
My Invention, as lastly before described, is applicable to all the purposes for
which ropes, cords, or lines are required, particularly for standing rigging,
and for raising and lowering heavy weights..
For mining purposes, any required number of cables may be laid together
side by side, by racketing, weaving, hitching, or seasoning, and for use in
steam ploughs and other agricultural purposes will be stronger and lighter
than any other rope, cable, or cord now in use for those purposes.
