PROVISIONAL SPECIFICATION.
Improvements in Rope Clips Employed in Surface and Mine Haulage.
We, WALTER ROBINSON, of Arthington Grove, Hunslet, Leeds, Engineer, and
ALFRED CROSSLAND, of Holly House, Middleton, near Leeds, Engineer, both in
the County of York, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct rope clips for use in surface and
mine haulage in such a manner that corves or trucks may be readily and firmly
attached to the travelling rope, and when so attached they are not liable to
become loose until the clip is released at the delivery end.
According to our invention we construct a casing having a hook for attachment
to the truck at its upper end, and the lower end of the casing is formed with a
jaw which is of suitable shape to embrace the under surface of the haulage rope.
Within the casing a slide is provided, working vertically over the jaw on the
casing, and the lower portion of the slide is formed with a friction surface suit-
able for gripping a rope between it and the jaw. Movement is imparted to the
slide by means of a toggle, the lower link being connected to the slide, and the
upper link to the casing, and on one of the links a lever is attached by means
of which the toggle may be moved across its centre, thus forcing the slide down
and retaining it in the down position.
The toggle may be forced across its centre against a spring, and this may con-
veniently be effected in the lever which would then form the spring and link
combined, or the said spring might be formed in the casing or slide as found
most convenient.
Instead of employing a spring, the upper link of the toggle could be fulcrumed
to a slide which would be forced and held in a down position by means of a
wedge passing through a slot in the casing.
In attaching a truck to the travelling rope, the clip is first hooked to the truck
and it is then turned down so as to bring the jaw under the rope, when on the
lever being actuated the rope is gripped between the jaw and the base of the slide,
thus firmly securing the truck to the travelling rope. When the truck reaches
its destination the lever is actuated in the reverse direction and the clip is at once
released.

We, WALTER ROBINSON, of Arthington Grove, Hunslet, Leeds, Engineer, and
ALFRED CROSSLAND, of Holly House, Middleton, near Leeds, Engineer, both in
the County of York, 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;-
-
The object of this invention is to construct rope clips for use in surface and
mine haulage in such a manner that corves or trucks may be readily and firmly
attached to the travelling rope, and when so attached they are not liable to
become loose until the clip is released at the delivery end.
In order that our invention may be clearly understood, we will proceed to
describe the same with reference to the accompanying drawings in which similar
letters of reference refer to like parts in all the figures.
Figure 1 is a part sectional elevation, and Figure 2 is a part transverse section
of a clip constructed according to our invention showing the same in the open
position; and Figure 3 is a part sectional elevation of the same clip shown in the
closed position.
A is a casing having a hook B at its upper end for attachment to the truck,
and the lower end of the casing is formed with a jaw C, which is of suitable shape
to embrace the under surface of the haulage rope. Within the casing A a slide D
is provided, working vertically over the jaw C, and the lower portion of the
slide D is formed with a friction surface suitable for gripping a rope between it
and the jaw. Movement is imparted to the slide D by means of a toggle centred
at F, the lower link E of which is connected to the slide D at the pin G and the
upper link to the casing A at the pin H.
The upper link is composed of a spring lever J, which is so constructed that it
tends to force the centre F and pin H apart, and the lever J may either be con-
structed of two separate parts riveted together as shown or it could be made in one
piece if thought desirable.
In attaching a truck to the travelling rope, the clip is first connected to the
truck by means of the hook B and it is then turned down so as to bring the
jaw C under the rope, when on the lever J being actuated the centre F is carried
across the centre line between the pins G and H thus forcing down the slide D
and securely holding it in the down position. The rope is thus firmly gripped
between the jaw C and the slide D and the truck is thereby firmly secured to the
travelling rope until the lever J is actuated in the reverse direction and the rope
released.
The chief wearing parts of the clip are situated on the under side of the slide D
and the upper portion of the jaw C, and in order to enable these parts to be
renewed as required the slide D is detachable on removing its pin G, and the
jaw C is provided with a detachable friction piece C¹.
The pins F and H might be connected by means of a non-pliable link such as
by making the inner end of the lever J solid, and in that case the necessary
spring would be contained behind the pin H or in the slide D.
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. The casing A having a jaw C at its base, in combination with the toggle
actuated slide D substantially as and for the purposes set forth

page_text: 2. The combination of the casing A, hook B, jaw C, slide D, link E and spring
lever J, substantially as, and for the purposes set forth.
3. The general arrangement, construction and combination of the various parts
forming the improvements in rope clips employed in surface and mine haulage,
substantially as described with reference to the accompanying drawings.
