PROVISIONAL SPECIFICATION.
Metallic Coupling for All Kinds of Ropes.
JAMES RICHARD HAYHURST Engineer 15 Primrose Bank Blackburn England,
do hereby declare the nature of this invention to be as follows:-
A perforated metallic tube or ferrule with a rough internal surface, made from
metal capable of being closed so as to grip the ends of ropes.
Also a taper plug to be inserted in the centre or core of the ropes.
The coupling to have as many holes as possible, each hole to have a jagged
edge protruding inside of the coupling.
The taper plug to be used for swelling the end of each rope.
The ferrule being full of small holes can be quickly reduced and caused to grip
the ropes by striking several blows with a hand hammer on a top tool. The
bottom tool may be a block of iron with a hollow part or seat for the ferrule to
lay in while being made to grip the rope. After partly reducing the ferrule a
smaller pair of tools may be used to still further reduce the ferrule and thus form
a positive & powerful grip.

Metallic Coupling Or All Kinds of ropes.
I, JAMES RICHARD HAYHURST, Engineer, 15 Primrose Bank, Blackburn,
England, 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 :-
This invention relates to metallic couplings for joining together two lengths of
rope, either formed from hemp, or from wire, or from combined hemp and wire,
or to couplings for joining together the terminal ends of a single length of rope.
A coupling constructed according to my invention consists of a perforated or
reticulated tube or open ended ferrule having a rough inside surface, or a tube
having a rough inside surface, of a bore sufficient to pass over two adjacent ends of
a rope or ropes to be coupled together.
The said coupling tube having protuberances upon its inside bore is closed upon
the ends of the rope or ropes to be coupled by gathering in or diminishing the
diameter of the coupling by swaging or by contracting tools.
Figure 1 of the accompanying drawing represents the opposed ends of two
lengths of hempen rope, joined together by a closed metallic coupling constructed
according to one form of my invention.
Figure 2 represents a longitudinal vertical section of the same, showing a double
coned or taper plug or tongue forced into the middles of the adjacent ends of the
coupled rope lengths.
.
Figure 3 represents (in section) the coupling upon the opposed ends of two
lengths of rope, before the same is closed or contracted, and made to grip and
hold onto the rope ends by the roughened inside surface.

page_text: Figure 4 represents a transverse vertical section of the coupled ropes Figure 1,
upon the dotted line x-x.
Figure 5 represents two lengths of rope joined together by the said metallic
coupling Figure 1, but without the double taper plug breaking the butt joint of
the coupled rope ends.
Figure 6 shows in section and upon an enlarged scale a portion of the walls of
the coupling, representing how the inside boundary edges of the holes stand out
from the inner surface, and are burred, fagged or roughened.
Figure 7 is an underside plan of Figure 6.
Figure 8 represents upon an enlarged scale a modified form of my invention.
In this arrangement the holes are made by a penetrating tool, which, in forming
the holes, forces the metal into conical burrs or eyelets, which, when closed upon
the rope ends, imbed therein.
Figure 9 represents an underside plan of Figure 7.
In Figures 1 to 9 a is a reticulated and tubular metallic coupling, with the
holes or piercings a¹, having fangs, burrs or raised and roughened edges a³,
standing out from the inside, so that when the tubular coupling is contracted by
swaging or otherwise, and closed upon the ends b', c', of the ropes b and c, the
said burrs or standing out parts are forced into the material of the said ends and
the surface parts of the ropes force themselves partly up the holes or interstices
in the coupling from the inside, hence additional gripping or holding means.
To break the butt joint formed by the opposed ends and c¹ of the ropes b and c,
a plug or tongue piece d, is forced into the middles of the said ends.
Figure 10 represents a modified form of my invention, in which spike-like
roughings are formed on the inside bore of the tubular coupling by impressing
tools. Figure 11 is an underside plan of Figure 10.
a is the coupling, and a² are roughened or spike projections, standing out from
the inside bore of the same, and formed by sinking the holes a', from the outside,
although the said roughenings or inside teeth or spike-like projections may be
formed in other ways.
Figure 12 represents a metallic coupling formed from sheet metal by making
the same dovetail edged as at Figure 13 and then locking the same together.
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 :-
:-
First. A rope coupling, consisting of a short length of metallic tubing, or an
open-ended ferrule, with the inside bore roughened, toothed or burred, substantially
as and for the purpose as described and set forth.
Secondly. A rope coupling, consisting of a short length of reticulated metallic
tubing, or of an open-ended and pierced ferrule, with the inside bore formed with
outstanding burrs, serrations or teeth surrounding the piercings, substantially as
and for the purpose as described and set forth.
Thirdly. The improvements in means for coupling the ends of ropes, substantially
as herein described and set forth.
Dated this 15th day of December 1894.
