A PORTABLE WIRE ROPE AND CABLE STOPPER
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We VERNON WILLIAMS HALL, of 122 Leadenhall Street in the City of London, .
Master Mariner, and HENRY EDWARD LESTER, of Royal Albert and Victoria Docks
in the County of Essex, Engineer and Shipbuilder, do hereby declare the nature of
our invention for "A PORTABLE WIRE ROPE AND CABLE STOPPER," to be as
follows:-
Our Invention consists of a portable wire rope stopper or compressor, which can
be carried about and used in any part of a vessel, wharf, or other place where it
may be required-It is equally applicable either to wire or hemp ropes or cables.-
It consists essentially of a tube of sufficient size to embrace the rope, and provided
with a means of firmly gripping the rope throughout the whole length of the tube;
at the sides or end of the tubo, an eye, hook, or shackle is provided by means of
which the stopper can be attached by chain or strap to any convenient point of
support, either on board ship, on a wharf, or any other place where it may be
required, so that the stopper can be attached where most convenient and at once
adjusts itself in the direction required, and the strain on the rope is therefore
always in the direction of its length, and does not distress it.
In practice, the mode in which we prefer to carry out our Invention is to
construct the tube in two halves longitudinally, and hinge them together by two of
their opposite sides; the other sides being connected by eye bolts and wing nuts.―
To introduce the rope, the nuts are slacked, the eye bolts turned down, and the
tube opened by its hinges; the rope is then laid in, the tube closed, the eye bolts
turned up, and the wing nuts screwed down, by which means the rope is firmly
gripped between the two halves of the tube.--Should it be desired to increase the
holding power of the tube upon the rope, its interior surface may be roughened, or
may be provided with cavities in the one half, and corresponding bosses or
swellings in the other half.-In all cases, we provide on one end or other part
of the tube, an eye, hook ring, or other suitable device for enabling it to be
attached wherever required.

SPECIFICATION.
We, VERNON WILLIAMS HALL, of 122, Leadenhall Street, in the city of London,
Master Mariner, and HENRY EDWARD LESTER, of Royal Albert and Victoria Docks,
in the county of Essex, Engineer and Shipbuilder, do hereby declare the nature of
our invention for "A PORTABLE WIRE ROPE AND CABLE STOPPER" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
Our invention consists of a portable wire rope stopper or compressor, which can
be carried about and used in any part of a vessel, wharf or other place where it
may be required-It is equally applicable either to wire, or hemp ropes or cables,
and in construction consists essentially of a tube of sufficient size to embrace the
rope and provided with means for firmly gripping the rope throughout the whole
length of the tube-At the sides or end of the tube, one or more eyes, hooks or
shackles are provided by means of which the stopper can be attached by a chain
or strap to any convenient point of support, either on board ship, on a wharf, or
any other place where it may be required, so that the stopper can be attached
where most convenient and at once adjusts itself in the direction required and the
strain on the rope is therefore always in the direction of its length, and does not
distress it.
The mode in which we prefer to carry out our invention in practice is as follows,
reference being bad to the accompanying sheet of drawings to more clearly explain
the construction thereof-
Fig. 1 is a side elevation, Fig. 2 a plan, Fig 3 a longitudinal section and Fig. 4.
an end elevation of the stopper closed and holding a rope-Fig. 5 is a cross section
shewing the stopper open with the rope laid in place.
The same letters refer to the same parts in each figure.
The stopper is formed of a tube constructed in two halves A and B, the said
halves being connected by the hinges C and D, on one side, and on the other side
by the eye bolts E and F.
The said eye bolts are hinged to the lower half of tho tube, and slots are
provided in the edge of the upper half to receive the shank of the bolt which is
provided with the capstan-head nut G.
To introduce the rope tho nuts are slackened sufficiently to enable the eye bolts
to be turned down, when the tube can be opened, and the rope laid in place as
shewn clearly in Fig. 5-The tube is then closed, the eye bolts turned up and tl.e
nuts screwed down sufficiently to grip the rope as shewn in Fig. 4-To increase the
holding power of the stopper, we usually prefer to provide its interior surface with
projections H Fig. 3.
Each projection on the one half of the tube being situated mid way between two
projections on the other half.
.A projection I is formed on each half of the tube at one end provided with
holes J to which shackles K are hinged by the pins L for attachment of the stopper
to any desired point of support, as previously described.

page_text: The capstan-head nuts shewn are convenient as being readily inanipulated by a
marlin spike or other similar article, but we do not bind ourselves to the precise
form of the said nuts, nor to the number of eye bolts and nuts and hinges used, nor
to the form of the other details of construction shewn, nor to the materials of
which we construct the apparatus.
In practice we usually form the tube of malleable cast iron, the bolts, pins and
shackles of wrought iron, and the nuts of gun metal.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
0
A portable wire rope and cable stopper constructed after the manner and for the
purposes substantially as herein set forth.
