Improvements in Rope and Cable Grips, and Clips for Underground
Haulage and the like. purposes.
I, GEORGE LYNAM, of 86, Wood Lane, Treeion, near Rotherham, in the County
of York, Colliery Deputy, do hereby declare the nature of my said invention
o be as follows:-
Although my invention is applicable to various kinds of rope haulage it is
more particularly applicable to the underground haulage in collieries where
endless wire ropes are employed.
The object of my invention is to provide a grip or clip which can be readily
attached or detached by hand from the haulage rope, and also provided with
appliances by which the grip on the rope is secured when the links by which it is
attached to the corves are in tension, and also with appliances by which, under
certain conditions the grip may be relaxed so as to allow the rope to run free
from the clip, as for example, when the leading car of a train of corves shall
come in collision with another train or like obstacle in front of it, or when the
corves by reason of an accelerated velocity due to inequalities in the road or from,
other causes should overrun the speed of the rope.
I carry out my invention in the following manner.
The body of my improved clip is constructed with a longitudinal recess, the
bottom of which will be parallel with the line of the rope when the clip is in
position for attachment, the upper part of this recess is made at an angle of about
one in five or thereabouts, with the bottom of the recess. previously described,
the space between the bottom and top of the recess being sufficiently wide to allow
of the introduction of a sliding wedge which is fitted so that the underside of the
said wedge is always parallel with the bottom of the recess.
To the front or narrow end of the wedge I provide a suitable shackle or links
to which is attached the hook by which the corves are connected, and I likewise
extend the narrow end of the wedge, in the form of a bowed arm, in an upward
direction beyond the said shackle or links, so as to insure its coming in contact
with an object like a train of corves or other obstacle in front, and by means
of which projecting arm, the wedge would be driven back and the grip on the
haulage rope relaxed.
In some cases the wedge is provided with slots formed parallel with its angular
side, by means of which and suitable pins or studs, it may be prevented from.
becoming detached from the body of the clip through the orifices at its rear end,
but in most cases the upward turned arm, and the shackles or links, will be
sufficient for this purpose.
About the centre of the upper half of the body of the clip, I provide a recess
for the short end of a lever by which the wedge can be moved backwards and
forwards longitudinally, the end of the lever being made long enough to enter a
suitably formed recess on the upper side of the wedge, so that as the long end of
the lever is moved in a direction opposite to that in which the rope is travelling,
the wedge would be made to slide forward and grip the rope. In like manner when

page_text: the long end of the lever is pushed forward in the direction in which the rope is
running, the wedge would be forced back in its recess and thereby the grip on the
rope relaxed.
In order to utilize this action for releasing the grip automatically, I bow the
long end of this lever so that it may project beyond the rear end of the body of
the clip sufficiently far to allow of the front end of a corve coming in contact
with the projecting end of the said lever before it can come in contact with the
body of the clip, and by such contact the long end of the lever would be forcéd
forward, the wedge would be driven backwards, and the grip on the rope relaxed.
The last named lever would be secured by a pin, bolt, or stud in its recess which
would also act as its fulcrum.
In some cases the body of my improved clip may be cast or otherwise formed
with the recesses herein described cored or formed out of the solid, and in some
cases it may be formed in two parts. bolted or otherwise secured together somewhat
after the fashion of a box lock, so that the moving parts may be readily examined,
removed and replaced.

Improvements in Rope and Cable Grips, and Clips for Underground
Haulage and the like purposes.
I, GEORGE LYNAM, of 86, Wood Lane, Treeton, near Rotherham, in the County
of York, Colliery Deputy, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:―
Although my invention is applicable to various kinds of rope haulage it is
more particularly applicable to the underground haulage in collieries where
endless wire ropes are employed.
The object of my invention is to provide a grip or clip which can be readily
attached or detached by hand from the haulage rope, and also provided with
appliances by which the grip on the rope is secured when the links by which it is
attached to the corves are in tension, and also with appliances by which under
certain conditions the grip may be relaxed so as to allow the rope to run free
from the clip, as for example when a train of corves shall come in collision with
another train of corves or like obstacle.
I carry out my invention in the following manner.
The nature of my invention will be better understood on reference to the accom-
panying sheet of drawings in which,
Fig. 1, is a side elevation of ay improved clip secured to a haulage rope, the
position of the wedge when drawn back being shewn by dotted lines.
Fig. 2, is an end elevation of the same.
Fig. 3, is a section taken on the line A, B, Fig. 1, in which the body of the clip
is formed in two parts bolted together, the wedge being drawn back.
Fig. 4, represents my improved clip gripping a haulage rope with a corve
attached.
The same letters refer to similar parts throughout the several views.
The body, a, of my improved clip is constructed with a longitudinal recess, b,
the bottom of which will be parallel with the line of the rope c, when the clip
is in position for attachment; the upper part of this recess is made at an angle of

page_text: bout one in five, or thereabouts, with the bottom of the recess previously
escribed, the space between the bottom and top of the recess being sufficiently
vide to allow of the introduction of a sliding wedge, d, which is fitted so that the
nderside of the said wedge is always parallel with the bottom of the recess.
To the narrow end of the wedge 1 provide a suitable shackle or links, e, to
which is attached the hook by which the corves are connected.
In some cases the wedge, d, is provided with slots, f, f¹, formed parallel with
ts angular side, by means of which and by suitable pins or studs it will always
nove parallel with the bottom of the recess, b, and the wedge by the same means
may also be prevented from becoming detached from the body of the clip through
the orifice at its rear end, but in most cases the shackles or links, ê, will be
ufficient for this purpose.
About the centre of the upper half of the body of the clip, I provide a recess
shewn by dotted lines for the short end g of a lever by which the wedge can be
moved backwards and forwards longitudinally, the short end of the lever being
made long enough to enter a suitably formed recess also shewn by dotted lines on
the upper side of the wedge d, so that as the long end, i, of the lever, is moved
in one direction, the wedge would be made to slide in the opposite direction and
grip the rope. In like manner when the long end of the lever is moved in an
opposite direction the wedge would be forced back and the grip on the rope
relaxed.
In order to utilize this action for releasing the grip automatically, I bow the
long end, i, of this lever so that it may project beyond the end of the body
of the clip, sufficiently far, to allow of the end of a corve or other obstacle coming
in contact with the projecting end of the said lever before it can come in contact
with the body of the clip or of the train of corves being hauled by it and by such
contact the long end of the lever would be actuated so as to release the grip on
the rope. The last named lever would be secured by a pin, bolt, or stud j which
would also act as its fulcrum.
In some cases the body of my improved clip may be cast or otherwise formed
with the recesses herein described cored or formed out of the solid as shewn in
Figs. 1, and 2, and in some cases it may be formed in two parts bolted or other-
wise secured together somewhat after the fashion of a box lock, so that the moving
parts may be readily examined, removed, and replaced, as shewn in Fig. 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
",
the
1. In rope and cable grips for underground haulage and the like purposes,
arrangement and combination of parts and appliances comprising, the clip, a,
provided with a sliding wedge, b, such wedge being actuated by a lever, having
rope,
a long end, i, and a short end, g, for securing or relieving the grip on the
by hand, and also so arranged that tension on the hauling links or shackle, ee
tightens the grip of the wedge upon the rope when in use, and in case of collision
the automatic release of the grip on the rope by the action of the said lever, and
5 wedge, in the manner and for the purposes substantially as herein described and
illustrated.
