Improved Rope Grip.

We, JAMES CAMPBELL, Engineer, and Joy TELFER, Consulting and Marine
Surveyor, both of 3 Brackentwaite, Whitehaven, in the County of Cumberland,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to an improved screw grip which consists of an apparatus
having two sides or jaws hinged to each other to permit the jaws to open and shut
to admit a rope. On one side we construct an elongated shaped frame with a pro-
jecting block at the top and the jaw at the bottom; and a short distance from the
jection of a suitable shape. To the short half grip is an arm of sufficient length
so that a pivoted trigger pawl will engage with the same in fixing the jaws in
position when closed, this said pawl is pivoted to the top block. Both blocks are
base of the frame we hinge the other short jaw this said jaw being hinged to a pro-
drilled and tapped to receive a long screw which elevates or depresses a movable
screw down block between the two jaws on to the rope. In the top block we insert
in a hole a handle in order to hold the screw grip.
The movable block travels up or down inside the jaws by means of the long
screw operated by a bar handle, wheel, or the like, and when fixed in position it
will be impossible for the short jaw to be put out of order by any amount of
pressure put upon the rope.
The movable block slides in grooves cut in each of the two sides or jaws of the
apparatus.
A suitable block is cast or fixed at the back of the long frame exactly opposite
the block to which the short jaw is hinged.

We, JAMES CAMPBELL, Engineer, and JOHN TELFER, Consulting and Marine
Surveyor, both of 3 Brackentwaite, 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.

page_text: 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 theron.
Fig, 1, is a back elevation of the apparatus.
Fig. 2, is a side elevation of the apparatus:
Fig. 3, is a front elevation.
In carrying our invention into practice we construct on one side an elongated
shaped frame a with a projecting block b at the top and the jaw e at the bottom;
and a short distance from the base of the frame a we hinge the other short jaw d
this said jaw d being hinged to a projecting piece e of a suitable shape. To the
short half grip or jaw d is a lever arm f of sufficient length so that a pivoted
trigger pawl g will engage with the same in fixing or locking the jaws c and d in
position when closed, this said pawl g is pivoted to the top block b. The pawl g is
provided with a wedge n cut on its face to an angle to correspond with the inside
angle of the lever arm f. Both blocks b and e are drilled and tapped to receive a
long screw h which elevates or depresses a movable screwdown block or press i
between the two jaws c and d on to the rope . In the top. block 6 we insert in a
hole a handle in. order to hold the screw grip.
The movable block or press i travels up or down inside the jaws by means of the
long screw h operated by a bar handle 7, wheel, or the like, and when fixed in
position it will be impossible for the short jaw d to be put out of order by any
amount of pressure put upon the rope.
The movable block or press slides in grooves m cut in the interior of each of the
two jaws c and d of the apparatus.
A suitable block e is cast or fixed at the back. of the long. frame a exactly
opposite the block to which the short jaw is hinged.
The object of this invention is to be able to connect and disconnect an endless
wire rope whilst in motion for all wire rope haulage with bogies and the like.
The rope by lifting the pawl can be freed instantaneously.
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 the combination of the frame a projecting block b jaw c
hinged jaw d block e lever arm, f pawl g wedge n screw h block or press i hole k
handle and grooves m, substantially as herein described and according to the
accompanying drawing.

2. In a screw grip, the combination of the apparatus having two sides or jaws
hinged to each other to permit the jaws to open and shut to admit of a haulage
wire rope with a pivoted pawl and a screwdown block, substantially as described.
3. In a screw grip, the combination of the various parts to form the apparatus
above described in this specification for the purpose specified.
