Improvements in or connected with Means of Connecting Ropes or
Cords, and Hauling Electric or other Cables.
1, ARTHUR ANNESLEY VOYSEY, of St. Valery. Finchley Road, West
Hampstead, in the County of Middlesex, Electrical Engineer, do hereby declare
the nature of this invention to be as follows :-
This invention has reference, mainly, to the modes of or means for hauling
electric and other cables generally, and is particularly applicable for hauling
electric cables (especially of large size) into pipes or culverts.
In the application of my invention to cables used for electric lighting, and for
conveying electricity for other purposes, the strands of the cable, in the case of its
being covered with insulating material, are bared. Over this end, consisting of the
copper or other strands, 1 employ and fit a ring or equivalent metal ferrule which
may be tapered on the inside, the enlarged part being nearest the end of the cable.
In connection with this, I employ a pin which I drive in to the end of the cable, by
which means the strands are spread outwards and pressed firmly onto the inside
surface of the ferrule, and thus the cable and ferrule are firmly fixed together; and
the tendency of the ferrule, when pulled away from the end of the cable, is only to
make the bond the tighter.
Onto the ferrule I may screw or equivalently fit a cap (which, if desired, may be
square, or other form as to be capable of being turned by a key or spanner) to
which is connected the hauling or drawing rope. When this cap is screwed onto
the ferrule the means of pulling or hauling it is complete. The ferrule may also be
squared on the outside, so that it may also be held by a key or spanner.
The pin may have a suitable head, or so constructed, that it can be readily
withdrawn from the cable end when so desired; and also it may be made rough
or irregular, if desired, so as to be less liable to come out of itself after it i
knocked in.
The outer diameter of the connections above described can be made as small as,
or smaller than, the diameter of the insulated portion of the insulated cable,
thereby avoiding all trouble with respect to its passing through a pipe or other
conduit.
The rope, in some cases, may be connected directly to the ferrule, if desired.
Some of the effects produced by the use of my invention are:- That no portion
of the cable, when applied to electric cables, is wasted, as the strands of the end,
after the pin and ferrule is removed, can be pressed back into place; a saving in
time; and a free and non-obstructed connection is afforded.
The herein described invention is not restricted to the form or construction of
parts herein above particularly specified, as these may be modified in various ways
without departing from the scope of the invention and it may be applied in part
or the whole to connections for cables for the purposes specified. As previously
stated, it, moreover, is not confined in its application to any particular or type of
cable.

Improvements in or connected with Means of Connecting Ropes or
Cords, and Hauling Electric or other Cables.
I, ARTHUR ANNESLEY VOYSEY, of St. Valery, Finchley Road, West
Hampstead, in the County of Middlesex, Electrical 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 :-
This invention has reference, mainly, to modes of or means for hauling electric
and other cables generally, and is particularly applicable for hauling electric
cables (especially of large size) into pipes or culverts.
In the application of my invention to cables used for electric lighting, and for
conveying electricity for other purposes, the strands of the cable, in the case of its
being covered with insulating material, are bared. Over this end, consisting of the
copper or other strands, I employ and fit a ring or equivalent metal ferrule which
may be tapered on the inside, the enlarged part being nearest the end of the cable.
In connection with this, I employ a wedge or pin which I drive in to the end of the
cable, by which incans the strands are spread outwards and pressed firmly onto the
inside surface of the ferrule, and thus the cable and ferrule are firmly fixed
together and the tendency of the ferrule, when pulled away from the end of the
cable, is only to make the bond the tighter.
Onto the ferrule I may screw or equivalently fit a cap (which, if desired, may be
square, or of other form as to be capable of being turned by a key or spanner) to
which is connected the hauling or drawing rope. When this cap is screwed outo
the ferrule the means of pulling or hauling it is complete. The ferrule may also be
squared on the outside, so that it may also be held by a key or spanner.
:
The wedge or pin may have a suitable head, or so constructed, that it can be
readily withdrawn from the cable end when so desired and also it may be made
rough or irregular, if desired, so as to be less liable to come out of itself after it is
knocked in.
The outer diameter of the connections above described can be made as small as,
or smaller than, the diameter of the insulated portion of the insulated cable,
thereby avoiding all trouble with respect to its passing through a pipe or other
conduit.
The rope, in some cases, may be connected directly to the ferrule, if desired.
Some of the effects produced by the use of my invention are:-That no portion
of the cable (when applied to electric cables), is wasted, as the strands of the end,
after the pin and ferrule are removed, can be pressed back into place; a saving in
time and a free and non-obstructed connection is afforded.
The herein described invention is not restricted to the particular form or con-
struction of parts herein above particularly specified with reference to the drawings,
as these may be modified without departing from the scope of the invention and
it may be applied in part or the whole to connections for cables for the purposes
specified.
In the drawings which give one example of means for connecting ropes or cords
to and hauling electric or other cables according to my invention,
Figure 1 shews the parts separate and in longitudinal section;
Figure 2 shews the parts applied to the cable and connected up, in longitudinal
section; and
Figure 3 is an outside view of same.
With reference to the drawing, a is the ferrule or ring. fitting over the bared end
of the cable X, said ferrule having a tapered interior, and is threaded partly on its
exterior. is the headed wedge or pin for expanding the wires or strands of which
the cable proper is formed; and c is the cap which screws onto the threaded part
of a and has provided upon its end a swivel eye or ring c.

page_text: In applying this means of connection, the end of the electric cable is bared to the
extent shewn in Figure 1. The ferrule a is slipped over the bared end and the
wedge is then driven in to the end, whereby the wires are expanded in the manner
shewn in Figure 2. The cape is then screwed on the threaded part of a, and the
rope d being fixed to c', may then be hauled through the pipe or hole in which it
is required to lay it. When the cable has been pulled through the parts may be
removed from the end by unscrewing the cape from the ferrule a, and then with-
drawing the wedge b, after which the ferrule a can be removed as the wires can
then be compressed back into their original form.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is.:-
1. The means substantially as herein described of hauling cables of the kinds
herein referred to, consisting in employing on the end of the wires of the cable, a
ring, ferrule, or equivalent device, by which the cable is gripped, and on or in
connection with which a suitable means is provided to which the hauling rope or
cord is attachable; for the purposes specified.
2. A connection for enabling cables to be hauled, comprising a ring or ferrule
fitted over the end of the wires of the cable a wedge driven into the end of the
cable, and by which it is expanded in the inside of the ferrule or ring, and a cap or
device fitted on the ferrule or ring to which the hauling rope or cord is adapted to
be attached.
3. The means for connecting ropes or cords to, and hauling electric or other
cables, consisting of the parts specified, and constructed as set forth with reference
to the annexed drawings.
