Improved Socket for Securing the Ends of Wire Ropes.
We GEORGE ELLIOT PYLE of 23 Great George Street, Westminster, and
Sir GEORGE ELLIOT and GEORGE WILLIAM ELLIOT trading as George Elliot
and Company, of the sa e place, Wire Rope Manufacturers, 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 for object a novel construction of socket for securing the end
of a wire rope.
For the purpose of this invention, a strip or bar of iron or other metal is
forged with necks and swellings at certain parts, said strip or bar being then bent
or folded to form a ring shackle or toggle at the bight, the ends being free to be
clamped by rings, or by caps, fixed by bolts and nuts.
The end of the wire rope to be secured in such socket is first uncoiled or opened
for a given distance and long cone wedges, or other form, are inserted at one or
more places according to the number of swellings in the socket; the coil, twist, or
lay of the rope is then reclosed with the wedge or wedges in the part or parts as
placed. The end of the rope thus prepared is placed in the socket and the socket
legs clamped both above and below the swellings to fix the rope therein.
The cone wedge or wedges may be of wood or of metal as desired. After the
clamping a key or spile may be driven into the end of the rope to expand it into
one of the necks of the socket.
By this invention it will be impossible for a rope to "draw" through or from the
socket however severe the strain.
The invention will be clearly understood by the annexed drawings.
Figure 1 represents in sectional elevation a folded strip or bar shaped for the
purpose of securing the end of a wire rope and at the same time form a bight for a
shackle or link for the attachment to any article.
Figure 2 is an external elevation of the strip or bar with rings and a clamp in
the position it is intended they should occupy to fix the two legs of the strip or bar
into close contact with the rope.
Figure 3 shows a similar view to Figure 1 but with two swellings in the length
of the legs so that a rope can be gripped and clamped at two places.
Figure 4 is a view through the lines a, a, of Figure 2 to show the clamping caps and
the method of fixing them.
Figures 5 and 6 are detached views of some cone wedges which can be used in
conjunction with any other shape of wedge, which shape is determined more or less
by the formation of the rope or kind of rope.
A, A. is the strip or bar shaped with swelled out and sunken portions B, B, the
ends C, C, being slightly tapered for the reception of rings D, D, one of which is
shown driven home close up to the neck at E, E. F, F, are caps secured by screw
bolts G, G, over the neck H which is taperingly enlarged inwardly for the
extreme end of the rope to lie in but which end is preferably spread outwardly by
the insertion of the key or spile I.
The shapes of the cone wedges J, J, may be various of which a few examples are
shown. K is the bight for ring, shackle, eye or hook attachment.
The rope to be secured in the socket forming the main feature of this invention
may be of the usual lay or twisted kind but the invention is more particularly
intended for what is known as a locked wire rope now so well known. The
invention is well adapted for wire ropes in use for ships standing rigging, for
structural stays, for wire rope tramways, for hauling from the fact that from the
closeness of the lay or twist and the constant bite or hold that each wire has to its
DO37

page_text: neighbouring wires, no fracture of any wire could extend beyond a few inches so
that the faulty one could be removed without affecting the general strength of the
rope, whereas with an unlocked wire rope a fractured wire may curl off for a long
distance and reduce the strength of the rope to a disadvantageous and sometimes a
ruinous extent.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The invention of socket shown in the annexed drawings with swellings and
necks and with hollows as set forth.
2. In combination with a swelled and necked socket as herein set forth and shown
the employment of cones half cones or like wedges within the opened out and
reclosed wires of a rope.
