PROVISIONAL SPECIFICATION.
Improvements in Rope Grips or the like.
I, WILLIAM PELHAM BULLIVANT of 72 Mark Lane in the City of London,
Wire Rope Maker do hereby declare the nature of my invention to be as
follows:-
•
My invention has for its object to provide a simple and efficient nipper for
gripping ropes or the like. A nipper constructed according to my invention
consists of two moveable jaws shaped at their opposed faces to grip the rope
between them. These jaws are mounted by pins or otherwise upon a plate so that
the said jaws can move towards each other to grip the rope and away from each
other to release it. Connected with each jaw or with each pin by which each jaw
is attached to the plate is a lever or arm each lever or arm being provided with a
shackle or other means for the attachment of the hauling rope or device or of a
loop to which the hauling rope or device is attached. When the hauling rope or
device is strained the levers or arms act on the jaws which grip firmly the rope or
the like to be hauled between them. When the haulage strain is relaxed the jaws
open and release the rope or the like. Each jaw and its arm or lever may be
slipped upon a pin common to both and a latch may be provided hinged to one pin
and taking over the other to secure the parts in position."

Improvements in Rope Grips or the like.
I WILLIAM PELHAM BULLIVANT of 72 Mark Lane in the City of London,
Wire Rope Maker, 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 :-
My invention has for its object to provide a simple and efficient nipper for
gripping ropes or the like. A nipper constructed according to my invention
consists of two movable jaws shaped at their opposed faces to grip the rope
between them. These jaws are mounted by pins or otherwise upon a plate so that
the said jaws can move towards each other to grip the rope and away from each
other to release it. Connected with each jaw or with each pin by which each jaw
is attached to the plate is a lever or arm each lever or arm being provided with
means for the attachment of the hauling rope or device or of a loop to which the
hauling rope or device is attached.. When the hauling rope or device is strained
the levers or arms act on the jaws which grip firmly between them the rope or the
like to be hauled.
When the haulage strain is relaxed the jaws open and release the rope or the
like. Each jaw may be slipped upon a pin common to both and a latch may be
provided hinged to one of the pins or bolt on which the levers are mounted and
made to engage the other pin or bolt to secure the parts in position.
In order that my invention may be well understood I will further describe the
same with reference to the accompanying drawings
Figure 1 of which is a front elevation partly in section and Figure 2 a sectional
plan of a rope gripping device constructed according to my invention and Figure 3

page_text: is a front elevation and Figure 4 a sectional plan of a modified arrangement of the
movable jaws.
Referring to Figures 1 and 2 A represents two movable jaws having their
opposed faces recessed at a to receive the rope or the like to be gripped. These
jaws are mounted on bolts C carried on or in a frame or plate B, on each of which
bolts C is also mounted a lever D having a cam shaped or eccentric boss or end d
which when the levers are turned in one direction act on the jaws A to move them
towards each other and so grip the rope for the like placed between the said jaws,
the holes e in the jaws through which the bolts C pass being elongated to admit of
this motion.
The outer or free ends d² of the levers D are connected by any suitable means to
a-hauling rope or device so that when strain is put on the said hauling rope or
device both levers D will be caused to turn on the bolts C in the direction to move
the jaws inwards and cause them to grip the rope for the like. When the strain
is off the hauling rope or the like, the levers D may be turned in the reverse
direction so as to remove the pressure of their cam shaped bosses from the jaws A
which will then be free to open out or separate and so release the rope from their
grip.
The bolts C project some distance through the bosses d of the levers C and to
the end of one of these bolts as shewn at e is hinged one end of a plate, bar or
shackle E the opposite end of which plate or the like being provided with a hole g
through which the end of the other bolt C passes when the plate or shackle E is in
its closed position, a pin or collar h being then passed through a hole in the end of
this bolt to retain the plate or shackle in its closed position and thus securely hold
the parts together.
In the arrangement illustrated by Figures 3 and 4 the jaws A instead of being
mounted on the bolts C as herein before described are both hinged to a pin.C
common to both jaws the said pin being arranged at right angles to the bolts C in
a slot or opening b in the frame or plate B. The other parts of the apparatus are
similar to those shewn in Figures 1 and 2 and are indicated by the same letters of
reference and do not require to be further described.
Either device described may be employed for hauling purposes or as a rope
stopper, in the latter case the plate carrying the jaws and levers may be fixed to
the deck of a vessel or in any other required position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In apparatus for gripping ropes or the like the combination with movable
jaws of levers arranged to act directly on the jaws to move them towards each.
other so as to cause them to grip a rope or the like placed between the jaws
substantially as hereinbefore described.
2. The combination and arrangement of parts constituting the device for gripping
ropes or the like substantially as hereinbefore described and illustrated by Figures
and 2 of the accompanying drawings.
3. The combination and arrangement of constituting the device for gripping
ropes or the like substantially as hereinbefody cribed and illustrated by Figures
and 4 of the accompanying drawings.
