A New or Improved Capping, Capling, or Coupling, for the Wire or
other Ropes and Conductors of Mine and other Cages, and for
Various other Articles and Purposes.
I CHARLES HOLCROFT of Trindle House Dudley in the County of Worcester Iron
Master do hereby declare the nature of this Invention to be as follows
My invention is specially applicable to the capping capling or coupling employed for
attaching the wire ropes of mine or other cages to the shackles with which the hooks
of the said cages are engaged and I will describe my said invention as applied to such
a capping capling or coupling but my invention may also be used for other purposes as
herein after pointed out.
The body of an ordinary capping or capling consists of a doubled or folded piece of
iron or steel between the halves or sides of which the rope is gripped. The bend or
eye part of the capping requires to be heated before the sides can be opened out for
putting it upon or taking it off the rope.
In my new or improved capping the beating referred to is dispensed with and the
said capping is more securely and expeditiously attached to the rope than the ordinary
capping.
In constructing a capping or capling according to my invention I proceed as
follows
I construct the body of the capping or capling of a conical chamber made in halves
hinged together at their larger bottom ends so that the said halves can be opened from
or closed upon one another. When the two halves are closed upon one another and
fastened together a conical chamber is formed for receiving the end of the rope. The
top or smaller end of the conical chamber of the capping is of somewhat larger diameter
than the rope to be capped or coupled and the bottom end of the said conical chamber
or the end nearest the hinge joint is about twice the diameter of the smaller end.
About two thirds of the exterior of the hinged chamber from the wider end thereof is
conical and the part above the external conical portion described is screwed for
receiving a long strong screw nut or cap for binding the two halves of the capping
together.

page_text: In addition to the said screw nut or cap a strong hoop or ring is fitted and driven
upon the conical exterior of the jointed capping for drawing the halves of the said
capping together before the screw nut or cap is screwed on. This hoop or ring may
be secured in its place by any convenient fastening in addition to driving it tightly
home on the exterior of the capping. About midway between the pin of the hinge
joint and the larger end of the conical chamber an eye is formed for receiving a strong
pin. By means of this pin a shackle is secured to the capping with which shackle the
hook of the cage is engaged. This shackle may be modified to suit the purpose for
which the rope is intended to be used.
The connection between my new or improved capping or capling and the wire rope
is made as follows.
The screw nut or cap followed by the hoop or ring are first threaded on the end of
the wire rope and the said end of the rope is then untwisted for the required length in
order that the various strands may be left free for manipulation. The wires on the
outside of the rope are bent back upon themselves the next outer ones are bent back
upon these and so on until the strands of wire roughly approximate to the form of the
conical chamber of the capping. The end of the rope so treated is then placed between
the two halves of the conical chamber which are closed upon it and the hoop or ring is
driven firmly home until the binding screw nut can be screwed on.
The said nut is then screwed upon the screwed end of the capping so as to bind
together the two halves of the capping. The bent ends of the wire rope formed into
a cone are thus enclosed between the halves of the capping and the said rope is firmly
secured in its place that is cannot be drawn out of the capping.
My invention is well adapted for capping wire pit ropes and conductors as already
described but it can also be applied to the capping of wire ropes for suspension bridges
wire and other ropes for hoists ship's rigging and the like and for other purposes where
a secure attachment for a wire or other rope or conductor is required.

other Ropes and Conductors of Mine and other Cages, and for
Various other Articles and Purposes.
I CHARLES HOLCROFT of Trindle House Dudley in the County of Worcester, Iron
Master do hereby declare the nature of my 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 is especially applicable to the capping capling or coupling employed
for attaching the wire ropes of mine or other cages to the shackles with which
the hooks of the said cages are engaged and I will describe my said invention as
applied to such a capping capling or coupling but my invention may also be used
for other purposes as hereinafter pointed out.
The body of an ordinary capping or capling consists of a doubled or folded
piece of iron or steel between the halves or sides of which the rope is gripped.
The bend or eye part of the capping requires to be heated before the sides can
be opened out for putting it upon or taking it off the rope.
In my new or improved capping the heating referred to is dispensed with and
the said capping is more securely and expeditiously attached to the rope than the
ordinary capping.
In constructing a capping or coupling according to my invention I proceed as
follows:
I construct the body of the capping or capling of a conical chamber made in
halves hinged together at their larger bottom ends so that the said halves can be
opened from or closed upon one another. When the two halves are closed upon
one another and fastened together a conical chamber is formed for receiving the
end of the rope.
The top or smaller end of the conical chamber of the capping
is of somewhat larger diameter than the rope to be capped or coupled and the
bottom end of the said conical chamber or the end nearest the hinge joint is about
twice the diameter of the smaller end. The exterior of the hinged chamber from
the wider end thereof is conica! except at the smaller end which is screwed for
receiving a strong screw nut or cap for binding the two halves of the capping
together.
In addition to the said screw nut or cap one two or more strong hoops or rings
is or are fitted and driven upon the conical exterior of the jointed capping for
drawing the halves of the said capping together before the screw nut or cap is
screwed on. About midway between the pin of the hinge joint and the larger end
of the conical chamber an eye is formed for receiving a strong pin. By means
of this pin a shackle is secured to the capping with which shackle the hook of the
cage is engaged. This shackle may be modified to suit the purpose for which the
rope is intended to be used.

page_text: Figures 1 and 2 represent elevations taken in planes at right angles to one
another of my new or improved capping, capling or coupling for the wire rope of
a mine cage and Figure 3 is a vertical section of Figure 2.
The same letters of reference indicate the same parts in the several Figures.
a a² is the conical chamber constituting the body of the capping the said chamber
or body being made in halves hinged together by the hinge joint b at their larger
bottom ends so that the said halves can be opened out or separated to receive the
end c² of the wire rope c and closed upon the said end c² as represented iu
Figure 3, the strands of which end care untwisted and bent back into the form
of a cone as represented.
The shape of the conical chamber a a² of the capping is best shown in the
section Figure 3 from which figure it will be seen that the top or smaller end of
the capping is of somewhat larger diameter than the rope c to be capped and the
bottom end of the said capping is about twice the diameter of its smaller end.
The exterior of the hinged chamber or capping a, a² from the wide end thereof
to nearly the smaller end is conical or taper but the said smaller end is parallel
and screwed externally at d for receiving the screw nut or cap e for assisting in
binding the halves a a² of the capping together; are strong hoops or rings
which are fitted and driven upon the conical exterior of the said halves of the
capping for drawing them together before the screw nut or cap e is screwed in
its place. The said hoops or rings ff may be secured in their places by any
convenient fastening in addition to driving them tightly home on the exterior of
the capping is the shackle with which the hook of the mine cage is engaged.
The said shackle is secured to the larger end of the capping a a2 by the strong
pin passed through an eye in the said larger end of the capping as seen in
Figure 3. The shackle y is fixed in its place after the two parts or halves of the
capping have been closed and drawn and bound together. The connection between
my new or improved capping or capling and the wire rope is made as follows :-
The screw nut or cape followed by the hoops or rings ff are first threaded on
the end of the wire rope e and the said end of the rope is then untwisted for the
required length in order that the various strands may be left free for manipula-
tion. The wires on the outside of the rope are bent back upon themselves, the
next outer ones are bent back upon these and so on until the strands of wire roughly
approximate to the form of the conical chamber of the capping a a² as seen at c²
in Figure 3. The end c² of the rope c so treated is then placed between the two
halves of the capping which are closed upon and the hoops or rings f, fare driven
firmly home until the binding screw nut e can be screwed on. The said nut e is then
screwed upon the screwed end d of the capping so as to bind together the two halves
of the capping as represented in the Drawing. The bent ends of the wire rope formed
into a cone are thus enclosed and firmly gripped between the halves of the capping
and the said rope is thereby firmly secured in its place, that is, cannot be drawn out of
the capping.
Instead of using a series of hoops or ringsff for driving upon and holding together
the two halves of the capping, one boop or ring only, preferably a long hoop or ring,
may be used; and the parallel end d and screw nut or cap e may be omitted and the
exterior of the capping be made conical from end to end the narrow conical plain end
of the capping in this case receiving a hoop or ring similar to one of the hoops f.
The screwed end of the capping and screw nut or cap represented in the Drawing
are especially useful when the capping is used in an inverted position that is with the
wider end upwards but when the capping is used in the position represented in the
Drawing there is not that tendency in the fixing hoops or rings to move or slide back
from their fixing position as when the capping is inverted and hence the screw nut or
cap may be dispensed with when the capping is used in the position represented but
by its use additional safety in the capping of the rope is afforded.
My invention is well adapted for capping wire pit ropes and conductors as before
described and illustrated but it can also be applied to the capping of wire ropes for
suspension bridges, wire and other ropes for hoists; ships rigging and the like and

page_text: for other purposes where a secure attachment for a wire or other rope or conductor is
required.
Having now particularly described and ascertained the nature of my inven-
tion, and the manner in which the same is to be performed I declare that I claim
as my invention :-
The new or improved capping capling or coupling for the wire or other ropes and
conductors of mine and other cages and for various other articles and purposes herein-
before described and illustrated in the accompanying drawing, the said capping capling
or coupling consisting essentially of a conical chamber made in halves and hinged
together at their larger ends the end of the wire rope or conductor being placed in and
enclosed and gripped hetween the closed halves of the capping by binding the said
halves together by means of a hoop or ring or hoops or rings driven upon the conical
exterior of the capping, whether the hoop or ring or hoops or rings be used alone or
in combination with a screw nut or cap screwed upon the smaller end of the capping
substantially as described and illustrated.
