COMPLETE SPECIFICATION.
Improvements in the Manufacture of Ropes and Cables.
I JOHANN TEODOR HAASE of Deichshausen, near Altenesch, Oldenburg,
Germany, 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:-
My said invention relates to hawsers cables ropes lines and the like and consists
in a new method of using steel wire in the manufacture of such articles whereby they
acquire greater elasticity and flexibility besides being very light and presenting
great resistance to breakage.
Referring to the accompanying drawings
Figures 1 and 2 are views partly in elevation and partly in longitudinal section
of ropes or cables made in accordance with my said invention.
Figures 3 and 4 are transverse sections through - and y-y of Figures 1 and 2
respectively.
Figures 5 and 6 represent heavy hawsers or towing cables of three cords each of
which is made according to my said invention.
About a core k (of pieces of cork rubber plaited or twisted cocoa fibre or other
elastic material) I plait a layer or pipe a of hemp cotton or other fibre. This
layer a may come immediately on the core k or over an intervening more softly
plaited layer b of hair or other material.
About the layer 61 plait an external covering d of thin steel wire. The meshes of
this plaiting are so far apart as to permit a bending of the ropa or cable by the
displacement of the meshes with regard to each other. In the ropes shown in the
drawing each strand is composed of two wires but a single wire or more than
two may be used. Instead of a single plaited layer of wire two or more such
layers may be used according to the strength of rope required.
In thicker ropes and cables a layer of hemp or the like may be applied (outside
the first wire layer) and another layer of wire may be plaited thereon and in the
case of very thick cables several such alternating layers of plaited wire and hemp
or the like may be used.
The separate layers of hemp jute cocoa or the like as well as the layers of steel
wire may instead of being plaited be twisted as in the usual method of rope making
as shown in Figure 5. In such case the separate wire strands d' are placed at
corresponding distances apart so as to admit of displacement with regard to each
other to permit of the bending of the rope. Or twisting and plaiting may be
combined as in Figure 6 where twisted layers of hemp and the like are combined
with plaited wires.
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 I
claim is
As a new article of manufacture a composite cable having an elastic core k of
pieces of cork rubber or other suitable elastic material with a superposed layer or
layers of plaited or twisted hemp jute or other fibres and steel wire plaited in

page_text: open meshes or twisted with spaces between substantially as and for the purpose
hereinbefore set forth and described.
