PROVISIONAL SPECIFICATION.
An Improved Fastening for the Ends of Wire Ropes.
I, ALEXANDER KELLAR, of Bute Docks, Cardiff, in the County of Glamorgan,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved method of securing the various strands at
the ends of wire ropes in their couplings, and principally consists in making the
coupling of a conical shaped shell; and in addition thereto, applying a conical plug
having an aperture in the direction of its axis, of a suitable shape and size, so as to
accomodate that portion of the rope called the bore, or as many of the wires as may
be desired.
The outside wires are forced against the internal surface of the shell of the
coupling by the action of the cone; but the internal core, and as many of the
internal wires of the rope as may be desired, are passed through the orifice in the
taper plug, and are held secure therein by means of a suitably shaped key or wedge
driven in tightly, thereby causing the central wires to be gripped securely, and inde-
pendently of the fastening of the outer wires of the rope. The object of this is to
prevent the conical plug from sliding out and away from its work when a strain
is brought to bear upon the rope. The plug may be made of a square section if
desired and fitted in the interior of the coupling of a corresponding shape that is to
say, the sides against which the strands are pressed are flat, so that upon the insertion
of the pyramidal shaped plug, the wires are gripped firmly against the interior of the
outside shell. Flat plates may be employed between each layer of wires if desired,
in order to increase the surface so as to obviate the necessity of lapping one wire
over the other, the central core being held as before described.

COMPLETE SPECIFICATION.
An Improved Fastening for the Ends of Wire Ropes.
I, ALEXANDER KELLAR, of Bute Docks, Cardiff, in the County of Glamorgan,
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 an improved method of securing the various strands at
the ends of wire ropes in their couplings, and consists in making the coupling of
a conical shaped shell, in combination with a conical plug having an aperture in
the direction of its axis, of a suitable shape and size, so as to accomodate that
portion of the rope called the core, or as many of the wires as may be desired, and
to receive a wedge; which latter operates as a fastener for the said portion indepen-
dently of the method of or means by which the outer strands or annular portion of
the rope is gripped.
The present invention is an improvement upon the one patented to me by Letters
Patent No. 148691885.
The said outer strands, or annular portion, are forced against the internal
surface of the shell of the coupling by the action of the conical plug or cone; but
the core, and as many of the central strands of the rope as may be desired, are passed
through the orifice or taper plug or cone, and are held securely therein by means of
a suitably shaped key or wedge driven in tightly, thereby causing the central wires
and core to be gripped securely, and independently of the fastening of the outer

page_text: from sliding out, and away from its work, when a strain is brought to bear upon the
rope. The wedge may be made of a square section if desired, and the interior of the
core of a corresponding shape, that is to say, the sides against which the central
strands are pressed are flat, so that upon the insertion of tho wedge, the wires shall
be gripped firmly against the interior. Flat plates may be employed between each
layer of wires if desired, in order to increase the surface so as to obviate the
necessity of lapping one wire over the other, the central core being held as before
.described.
In order that my invention, and the moans by which the same may be carried into
practical effect, may he thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying drawings which are to be taken as part of
this specification and read therewith.
Fig. 1 is a full size side elevation, partly in section.
Fig. 2 in a side elevation partly in section.
Fig. 3 is a section on the line A-B of Fig. 2.
Fig. 4 is a front elevation of Fig. 3.
Fig. 5 is a side elevation of the cone.
Fig. 6 is a front elevation of the cone.
Fig. 7 is a side elevation of the key or wedg
dge.
Figs. 8, 9, and 10 are respectively plan; transverse section; and plan, partly
in section, illustrating the method of connecting two rope ends by. my invention.
Fig. 11 is a sectional side elevation of a fastening with a square core.
Fig. 12. is a transverse section on the line -D.
Fig. 13 is an end elevation.
E is the well known conical shaped shell; and e, its cap.
F is the rope; f, a stop ring; g, the cone; h, the outer strands, or annular
portion, of the rope; i, the core or central strands; and j, the wedge. Figs. 2
and 3 shew the outer strands arranged in two annuli with a copper ferrule k
interposed.
I wish it to be distinctly understood that my presont invention does not confine
me in respect of the shape of the cone. In Figs. 1, 2, 3, 5 and 6, it is shewn
as circular in cross section; while Figs. 11, 12, 13, illustrate a cone square in cross
section. The shape of the shell is varied accordingly,
In some of the views, three strands are shewn as wedged in the aperture of the cone :
in Fig. 9 only one is shown. This number may of course be varied.
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 claimi
is :
The combination of cone having an axial aperture adapted to receive the core
or one or more of the central strands or both of a wire rope and a wedge with
the said. wedge so as to prevent the cone from being pushed out when the strain
is brought' to hear on the rope as set forth.
