Complete Specification Left, 2nd July, 1896-Accepted, 8th Aug., 1896
PROVISIONAL SPECIFICATION.
Improvements in Screw Grips for Ropes and the like.
We, JAMES CAMPBELL, of Lonsdale Iron Works, Engineer, and JOHN TELFER,
of 3 Brackenthwaite, Consulting and Marine Surveyor, both of Whitehaven, in
the County of Cumberland, do hereby declare the nature of this invention to be
as follows:-
Our invention relates to improvements in screw grips for ropes and the like,
which consists of an apparatus which has two sides or elongated jaws hinged at the
head on a connecting rod, to permit the jaws to open and shut to admit a rope. On,
one side we construct a wedge which travels into a casing, this said wedge is loosely
attached to the end of the screw and when the wedge is screwed down it nips the
rope by forcing the jaws together. On the opposite is provided another hinged jaw
which is kept in position by a back pawl. The rope can be freed instantaneously
by lifting the back pawl.
The screw passes through the head or nut and is operated by a handle or hand
wheel.
The object of the connecting rod is to connect the apparatus to the end of a
waggon or the like.
When it is required to connect a rope to the apparatus the jaws are opened and
the rope laid in a recess at the bottom of the grip, the wedge is then forced down
to close the jaws in operating the screw at the head by giving the handle a few
turns. The apparatus will grip a rope with any degree of pressure required and
when carriages, waggons or bogies, arrive at their destination it is only necessary
to lift the pawl which opens the lower jaw to release the rope clear of the grip.

COMPLETE SPECIFICATION.
Improvements in Screw Grips for Ropes and the like.
We, JAMES CAMPBELL, of Lonsdale Iron Works, Engineer, and JOHN TELFER,
of 3 Brackenthwaite, Consulting and Marine Surveyor, both of Whitehaven, in
the County of Cumberland, 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 :-
Our invention relates to improvements in screw grips for ropes and the like,
which consists of an apparatus which has two sides or elongated jaws hinged at the
head on a connecting rod, to permit the jaws to open and shut to admit a rope.
On one side we construct a wedge which travels into a casing, this said wedge is
loosely attached to the end of the screw and when the wedge is screwed down it
nips the rope by forcing the jaws together. On the opposite side is provided
another hinged jaw which is kept in position by a back pawl. The rope can be
freed instantaneously by lifting the back pawl.

page_text: The screw passes through the head or nut and is operated by a handle or hand
wheel.
The object of the connecting rod is to connect the apparatus to the enl of a
waggon or the like.
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a front elevation of the apparatus connected to a wire rope and the
connecting rod.
Fig. 2, is a side elevation of the apparatus with the wedge screwed down and the
jaws gripping the wire rope.
Fig. 3, is a back elevation.
The apparatus is constructed with two sides or jaws g and g2 hinged at head on a
connecting rod h or hook which allows the jaws g and g³ to open to admit the
rope j. On one side or half of gripfis fixed a casing e and on the opposite side
the said casing projects for the purpose of receiving a screw down wedged the
wedge being operated by a screw 6 travelling up or down in a nut c and handle a.
When the wedge d is screwed down it forces the jaw g and grip f together for the
purpose herein before described. At the back of the apparatus the lower jaw g' is
hinged to the half of grip fand is kept in position by a pivoted lever or pawl i
wedging itself between the balf of grip and the arm g' on the jaw of g³ as in
Figs. 1, and 2. The ropej can be freed instantly by lifting the pivoted lever or
pawl when the rope j drops clear of the jaws g and g².
When it is required to connect a ropej to the apparatus the jaws g and g² are
opened and the rope j laid in a recess at the bottom of the grip, the wedge d is then
forced down to close the jaws in operating the screw at the head by giving the
handle a few turns. The apparatus will grip a rope with any degree of pressure
required and when carriages, waggons or bogies, arrive at their destination it is
only necessary to lift the pawl i to release the rope j clear of the grip.
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 :-
1. In a screw grip for rope, the combination of the lower jaw 9 pivoted to the
grip and the lever or pawl i to engage with the arm g', and the screw down
wedged with the case e, substantially as herein described and according to the
accompanying drawing.
2. In a screw grip for rope, the combination of the handle a screw 6 nut c
wedge d wedge case e half of grip with lower jaw 92 arm g' and lever or pawl a
attached to a connecting rod h, substantially as herein described and according to
the accompanying drawing.
3. In screw grips for ropes, the combination of the various parts of the
apparatus described in the above specification and illustrated in the accompanying
drawing.
