I, WILLIAM CUTHBERT BLACKETT, of Kimblesworth, near Chester-le-Street in
the County of Durham, Mining Engineer and Manager of Kimblesworth Colliery
do hereby declare the nature of my invention for COMPOUND ATTACHMENTS OR
DOUBLE SOCKETS FOR METAL ROPES to be as follows:-
:-
My invention is designed for joining the ends of ropes, chains or other loads to
the ends of those Metal Ropes in which the wires are laid in successive coils or
layers, one upon another. It consists of a combination of two attachments or
sockets one within another, both attached to the rope, and so arranged that should
the outer one become detached by reason of the external coil of wires breaking,
the inner socket will come into use to the extent of its strength.
COMPLETE SPECIFICATION.
Compound Attachments or Double-sockets for Metal Ropes.
I, WILLIAM CUTHBERT BLACKETT of Kimblesworth, near Chester-le-Street, in
the County of Durham, Mining Engineer and Manager of Kimblesworth Colliery
do hereby declare the nature of my invention for COMPOUND ATTACHMENTS OR
DOUBLE-SOCKETS FOR METAL ROPES 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 designed for joining the ends of those metal ropes, in which
the wires, instead of being in strands, are laid in coils or layers one upon another,

page_text: to any other attachment or load: and consists of a combination of two attachments
or sockets, one within another, both attached to the rope, and so arranged that
should the outer one become detached by reason of the external wires breaking,
the inner socket will come into use, and exert its strength upon the load previously
held by the outer socket-One method of carrying this out is as follows, although
I do not bind myself to always use the details in the same way or even to use the
same details themselves: -
The inner socket A has its outside circular surface uniformly tapered or cone-
shaped throughout, the inside circular surface of which being concentric & therefore
cone-shaped for a portion of its length to B B, where it begins to run parallel to a
line drawn lengthways thro' its centre, thus terminating at its small end with a
sharp knife-edge c c-The external coil of wires of the rope being then loosened
and opened out, the inner rope is entered into this inner socket where it is fixed
(among other methods) by its wires being forced out by a spike, spikes, tapered
plug or plugs against a soft metal sheet lining the internal surface of the socket-
The link D is then affixed by the bolt E which has a countersunk head and is flush
with the socket.
A sheet of soft metal may then be placed around the outside of the inner socket
and the outer wires F, previously loosened, brought carefully and evenly around
and held temporally in place by a lap of wire.
The outer socket G, (which has been run up the rope previous to the fixing of
the inner socket A) having its inside circular surface tapered to correspond to the
outside of inner socket A and having been also lined with a sheet of soft metal, is
brought up over the outer wires F F, as forcibly as possible-The use of the soft
metal serves as a bedding for the wires and distributes more evenly among them
any strain that may occur.
The load may then be attached to the bolt H which is through the double eye
extended from the outer socket-Should the outer wires F F become, by any
means, broken or detached, the load will be held by the grip of the outer socket
upon the inner one or will fall together with the outer socket, until brought up
by the bolt I catching the link D attached to the inner socket A.
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 claim is
The combination of two Iron or Steel sockets or attachments for use with those
metal ropes specified hereinbefore, and take notice that I do not claim the whole of
the parts thereof.
