Improved Haulage Rope Clip.
ROBERT SIMPSON ANDERSON, Mining Engineer, Elswick Colliery and Joseph
FINNEY, Engineer Elswick Colliery Newcastle-on-Tyne, do hereby declare the
nature of this invention to be as follows:-
It is composed of four different parts viz.,
1. Main body composed of shank, with gib to secure to coal tub.
2. A hinged clamp fitted to the main body-clamp having a convex groove, &
main body a concave groove for taking rope.
3. A centre pin with flat bearing head, for holding grip of clamps on rope, and
4. A lever acting on a screw plane to produce grip of rope, which lever also
produces automatic disengagement of the rope at the end of the tub's journey.
Dated this 19th day of January 1894.

ROBERT SIMPSON ANDERSON Mining Engineer JOSEPH FINNEY Engineer
both of Elswick Colliery Newcastle-on-Tyne 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 :-
This invention relates more especially to clips .for attaching tubs, corves or
wagons to the ropes on rope railways in mines or other works.
It will be best understood by reference to the accompanying drawings in which
like letters indicate like parts throughout.
This rope clip is made to grip the rope equally, without adjustment, though the
size of the haulage rope may vary through wear and repairs and the addition of
new rope.
It can be made to suit any size of rope.
It is also adaptable to under tub as well as overtub haulage.
The material of which it is made is in some cases toughened cast steel which in
the case of breakage is weldable and the clip can be repaired with perfect ease
and despatch.
The rope clip consists of four different parts in its main construction, which are
as follows.
1st. The main body composed of shank A tapered off to a point at bottom and
having a gib B projecting far enough to pass under the tub hoop, securing the clip
to tub, and preventing same being detached, until the clip has been liberated from
the rope; on the top of this shank is formed the fast side of rope clip C. At the
square part of top of shank is formed a notch to receive the tongue a of hinged
clip, on the inside of rope clip C is formed at rope line a concave groove to take
rope; see drawing section on line X. Y. the top part laid suitably back for rope to
enter easily, and bottom part forming a fence up to which the opposite clip can go
and no further.

page_text: 2nd part is composed of hinged clip D and is precisely the same form as the
fast clip C, excepting that rope groove is convexed, so as to force rope into
concave groove of opposite side clip, and with the addition, that on the outside of
it, is formed one or more helical or screw surfaces 1. It is provided with tenon
or tongue to take, or fit into notch at top of shank, fórming hinge, secured by an
iron pin through cheeks of fast clip, and tongue of hinged clip, so as to move freely
under the action of lever and screw surfaces.
3rd part consists of a centre pin E. with flat head F, inside of head F lathed
up, to give perfect bearing on outside of main body of clip C, and to pass through
both clips C. D. also centre of screw plane H and I, taking on lever G aud
cottar K. This pin is provided with an oblong cottar hole, the cottar securing
in working position the lever, which has to produce grip of rope. The cottar hole
forms an important part of the arrangement for adjustment; as the rope or clip
itself wears down, by simply changing the cottar for one a little wider (slot hole in
centre of pin being sufficiently long to allow of this) the clip is at once adjusted
to allow for the wear, and give the full amount of original grip on the rope.
a
4th part consists of the lever G this is mounted by the side of the hinged
clip D, on the centre pin E. On the inside of the lever at boss is formed a
helical or screw surface H. cut through the centre on horizontal line;
corresponding helical or screw surface I. is formed on the outside of hinged
clip D. into which, and upon which, the lever acts to produce grip of rope.
On the outside of lever is formed raised boss J. slotted out in line with cottar
hole through centre pin E, when the cottar K is in position it fills this slot and
secures the lever G on centre pin E, so that when the lever G is pulled over its
helical or screw surface H acting on corresponding surface I of clip D forces this
clip over, carrying the rope with it into groove of main body clip C, thereby
forming the gripping force of this invention, by which the tub is held firmly to
rope until liberated automatically at end of tub's journey.
Having now particularly described and ascertained the nature of our said inven
tion and in what manner the same is to be performed, we declare, that what
we claim is,
1. A haulage rope clip for either under or over tub haulage in which the grip on
the rope is produced by the action of helical or screw surfaces substantially as
described.
2. A haulage rope clip for either under or over tub haulage in which the clips
can be adjusted to suit any size of rope by varying the width of the cottar
substantially as described.
3. A haulage rope clip for either under or over tub haulage which is attached to
the tub or wagon by means of a gib on the clip shank, and which cannot be
removed from its position, as long as the rope is in the clip substantially as
described.
4. In a haulage rope clip, the combination of a fixed clip formed integral with
the shank, a movable clip pivoted or hinged to the same and having one or more
helical or screw surfaces formed on it, a lever having corresponding helical or
screw surfaces engaging with the hinged clip, a central pin and cottar, substantially
as described and shewn.
5. A haulage rope clip, substantially as described and shewn.
