PROVISIONAL SPECIFICATION.
Improved Grip for Rope Haulage.
We, PETER THOMPSON, Engineer, and ERNEST THOMPSON, Fitter, both of 40,
Hardmans Street, Hollinwood, Oldham, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved clutch for use in connection with endless
rope haulage and provides a simple construction which can be easily connected
to or disconnected from the rope, and which is not liable to kink or bend the
rope.
The clutch is formed in two main parts which are hinged together at their
upper ends and are formed at their lower end with semi-circular grooves which
when the two sides are brought together make up a complete ring. Steel bushes
are fitted inside the ring which are removable and can be changed so that the
clutch will serve for various sizes of ropes.
When the two sides of the clutch are pressed together the rope is gripped
tightly between the two cheeks and on releasing the parts the clutch is at once
detached. To secure the clutch in operative position a metal band is employed
encircling it at the upper end. The sides of the clutch are curved or sloping so
that on this band being forced down the clutch is caused to bind upon the rope.
The upper end of the clutch is provided with cross pins which project at each
side and prevent the band becoming detached. The band may be provided at
one side with a small downwardly extending nib which bears upon the surface
of the clutch.
One side of the clutch is formed with a rearwardly extending hook of consider-
able strength, this hook enabling the clutch to be secured to the wagon or
other vehicle which is being hauled. The clutch can be easily connected to or
detached from the wagon as well as from the rope and it can also pass easily
over rollers or pulleys.

page_text: 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 to an improved clutch for use in connection with endless
rope haulage and provides a simple construction which can be easily connected
to or disconnected from the rope, and which is not liable to kink or bend the
rope.
The clutch is formed in two main parts which are hinged together at their
upper ends and are formed at the lower ends with semi-circular cheeks which
when the two sides are brought together make up a complete ring. Steel bushes
are fitted inside the ring which are removable and can be changed so that the
clutch will serve for various sizes of ropes.
When the two sides of the clutch are pressed together the rope is gripped
tightly between the two cheeks and on releasing the parts the clutch is at once
detached. To secure the clutch in operative position a metal band is employed
encircling its upper part. The sides of the clutch are curved or sloping so
that on this band being forced down the clutch is caused to bind upon the rope.
The upper end of the clutch is provided with cross pins which project at each
side and prevent the band becoming detached.
One side of the clutch is formed with a rearwardly extending hook of consider-
able strength, this hook enabling the clutch to be secured to the wagon or
other vehicle which is being hauled. The clutch can be easily connected to or
detached from the wagon as well as from the rope and it can also pass easily
over rollers or pulleys.
In order that this invention may be more readily understood, reference is had
to the accompanying sheet of drawings in which
Fig. 1 is a side view of my clutch and hook, and
Fig 2 an end view of the same.
As shown the clutch is made from two members A and A hinged together at a.
The lower parts of these members are of semi-circular form in cross section so
that on bringing them together a cylindrical passage is formed which receives the
rope and grips upon its surface. Semi-circular steel bushes B are provided on
the inner surfaces of the members and these bushes may be of different thicknesses
according to the diameter of the rope to which the clutch is fitted.
10 the part or member A at one end the strong hook C is fixed or may be cast
in one piece with it. This hook engages with a link or eye on the truck to be
drawn and is bent in the manner shown to obviate any danger of disconnection
on descending a gradient.
On the upper part of the clutch a loose metal band D is placed fitting around
the clutch and adapted to clip the two sides together when pressed down. This
band thus serves to cause the clutch to grip upon the rope and to travel along with
it. The cross pins E are fitted at the top of the clutch to prevent the band
becoming detached accidentally.
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:-
The improved clutch for rope haulage, comprising two parts pivoted together
having gripping surfaces to bear upon the rope, a hook on one end of the clutch
immediately above the rope, and a band fitting upon the upper side of the clutch
adapted to close the pivoted parts upon the rope, substantially as described and
shown and for the purposes specified.
