PROVISIONAL SPECIFICATION.
Improvements in Automatic Hauling or Driving Clips or Grips
for Rope Haulage.
MICHAEL GARTHORN 4 Ivy Terrace, South Moor near Chester le Street
County Durham Engineer, do hereby declare the nature of this invention to be as
follows:-
--
My invention relates to hauling or driving clips or grips for attaching tubs,
wagons or other carriages to a moving rope and consists of two forks connected and
acting together, one sliding to the right and the other to the left of the rope
horizontally in its moving direction, on a guide plate attached to the tub, wagon
or other carriage to be hauled or driven.
This guide plate has parallel sides on each half from the centre of attachment in
the direction of the hauling rope inclined horizontally at opposite acute angles to
the centre line of the hauling rope, that is one half to the right and the other half
to the left, thus forming an obtuse angle with its apex at the centre of attachment
to the tub, wagon or other carriage.
The weight and friction of the hauling rope on the V prongs of the two forks
when in motion, causes the forks to slide on the guide plate, one to the right and the
other to the left of the centre line of the hauling rope in the direction it is moving,
double wedging the hauling rope, and bending it in an S form, thus preventing the
rope sliding through the prongs of the forks and thereby hauling or driving the
tub, wagon or other carriage in the direction the rope is moving.
To receive the rope the prongs of the two forks have a normal centre position
on the guide plate, and then slide at opposite angles, in the direction the rope is
moving, until they clip, grip or bend the rope sufficiently to haul or drive the tub,
wagon or other carriage.
Having thus described the nature of my invention, what I claim is the construction
of a hauling or driving clip or grip for rope haulage, with two forks connected
together, and sliding on a guide piate, having parallel sides on each half from the
centre of attachment to the tub in the direction of the hauling rope inclined
horizontally at opposite acute angles to the centre line of the hauling rope,
substantially as described above, and shown on the drawings deposited herewith.

I MICHAEL GARTHORN of 4 Ivy Terrace, Sonth Moor, near Chester le Street,
County Durham, Engineer 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 statenient :-
My invention relates to hauling or driving clips or grips for attaching tubs,
wagons or other carriages to a moving rope, and consists of two forks connected
and acting together, one sliding to the right and the other to the left of the rope
horizontally in its moving direction, on a guide plate attached to the tub, wagon
or other carriage to be hauled or driven.
This guide plate has parallel sides on each half from the centre of attachment in
the direction of the hauling rope inclined horizontally at opposite acute angles to
the centre line of the hauling rope, that is, one half to the right, and the other half
to the left thus forming an obtuse angle with its apex at the centre of attachment
to the tub, wagon or other carriage.
I propose to apply this apparatus as follows,
Having attached the shank holding the clip to the tub, wagon or other carriage
in any convenient place and manner, the tube is given a forward motion by a creeper
or other means, in the direction of the moving rope, and the rope is placed between
the prongs of the two forks whilst the rope and tub are in motion.
The weight and friction of the hauling rope on the V prongs of the two forks
when in motion, causes the forks to slide on the guide plate, one to the right and
the other to the left of the centre line of the hauling rope, in the direction it is
moving, double wedging the hauling rope, and bending it in an S form, thus
preventing the rope sliding thro' the prongs of the forks, and thereby hauling or
driving the tub, wagon or other carriage in the direction the rope is moving.
To receive the rope, the prongs of the two forks have a normal central position
on the guide plate, and then slide at opposite angles, in the direction the rope
moving until they clip, grip or bend the rope sufficiently to haul or drive the tub,
wagon or other carriage.
This
When it is necessary, to release the rope from the clip, the tub is hauled up an
incline over a kip or crown in the tram-way, which has an opposite gradient on the
other side, down which the tub gravitates after being released from the rope.
release takes place by the strain being taken off the rope and clip when the tub
commences to gravitate, allowing the two forks to slide into their normal central
position on the guide plate, and the rope to disengage itself from the clip by keeping
the same angle as the incline rising to the kip or crown, whilst the tub is proceeding
down the opposite gradient.
To obviate any failure of the rope to disengage itself from the clip, a fender is
placed above the top of the clip (but clear of the same) at the same angle as the
downward gradient, under which the clip slides and forces itself from the rope.
DESCRIPTION OF DRAWINGS.
The drawings herein referred to are those left with the
Specification.

page_text: 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
The construction of a hauling or driving clip or grip for rope haulage, with two
forks connected together, and sliding on a guide plate having parallel sides on each
half from the centre of attachment to the tub in the direction of the hauling rope
inclined horizontally at opposite acute angles to the centre line of the hauling
rope, substantially as described above, and shown on the drawings left with the
Provisional Specification.
