Improvements in or relating to Clips for Rope Haulage.
We, ANDREW VALLANCE, and JOHN COLUMBINE, both of 188 Awsworth Road,
Ilkeston in the County of Derby, Engineers, do hereby declare the nature of this
nvention to be as follows :-
This invention relates more especially to improvements in haulage clips employed
on rope railways in mines or other works.
Clips of this description are usually formed of two parts one of which is pivotted
or hinged at its upper end to the main part which is provided with a hook for
attaching to the draw-bar of a tub or corve, the lower ends of both parts being
provided with jaws to receive the rope which are closed by a sliding link.
In our improved arrangement the jaws are closed and opened by a latch or lever
working across the inner face of the main part of the clip one end of which is
pivotted preferably at the back and its free end passing through a slot which
acts as a guide, projects beyond the clip so that it may be readily raised or
lowered.
This lever engages with a catch with an inner cam surface on the inner surface
of the free part formed so that when the free end of the lever is depressed the jaws
are drawn together and the rope firmly gripped.
The jaws are released by raising the free end of the lever which may also be
adapted to open the jaws and hold them in that position by means of a projecting
cam surface on the inner side of the free part of the clip against which the upper
edge of the lever will act as it is raised.
If desirable the lever may be formed with cam surfaces adapted to act on a catch
or stud secured to or forming part of the free part of the clip.
The hook is preferably hinged to the main part of the clip and is held in position
by a pin passing through lugs on the hook and clip respectively so that in case of
obstructions the pin which holds the hook in position will be broken and the hook
released thus preventing breakage of the hook or clip.

Improvements in or relating to Clips for Rope Haulage.
We, ANDREW VALLANCE and JOHN COLUMBINE both of 188 Awsworth Road,
Ilkeston, in the County of Derby, Engineers, 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 improvements in haulage clips employed
on rope railways in mines or other works.
Clips as generally used for this purpose are formed of two parts one of which is
pivotted or hinged at its upper end to the main part which is provided with a hook
for engaging with the drawbar of a tub or coive the lower end of both parts or jaws
being provided with recesses to receive the rope. The jaws of such clips have
hitherto been closed so as to grip the rope by the action of a link or sleeve
Erica 11

page_text: embracing and sliding on the two jaws; with this arrangement difficulty is
experienced both in attaching the clip to the rope and detaching it.
Our invention will be best understood by reference to the accompanying drawings
in which
Fig. 1 is a front elevation of our improved clip showing closed position.
Fig. 2 is a front elevation showing the clip open.
Fig. 3 is a side elevation and
Fig. 4 is a horizontal cross section of Fig. 3 on line X X.
The jaw a which is pivotted at a¹ to the main part 6 is closed and opened by the
latch or lever c working as shown across the inner face of the main part b of the
clip; it is pivotted preferably at c to an extension b' of the main part 6 and its free
end works in a slot formed in the part projecting from the face of the part b.
The free end of the latch or lever c may project a convenient distance beyond the
clip so that it may be conveniently raised or lowered and may if desired be turned
up as shown in Fig. 3 so that if it runs into an obstacle on the road it will be raised
and the clip released.
The lever c engages with the latch d which is secured to the jaw a and is provided
with an inner cam surface upon which the lower edge of the lever c operates when
it is depressed and thus forces the jaw a towards the part or jaw b so as to cause
them to grip the rope. The lever is provided at that part which engages with
the cam surface of the catch d with a side projection e at its lower edge which
engages in a corresponding recess in the lower part of the catch d so as to retain
the lever in its position when it is depressed and the clip closed. The catch d may
be secured to the part a by a bolt and nut the former being preferably formed
by an extension of the catch, an indiarubber washer y may also be placed between
the catch d and the jaw a so as to provide a means of adjustment for taking up
wear on the several parts.
When the lever is raised the jaw a is released and may be also forced open by
the action of the upper edge of the lever on either of the cam surfaces ¹ or both,
formed on the inner face of the jaw a, the lever c will also be retained in its upper
position by the weight of the jaw a and the clip will thus remain open as shown in
Fig. 2 until the lever c is depressed and is therefore always ready to be attached to
the rope.
If desirable the lever may be formed with cam surfaces adapted to act on a
catch d or stud secured to or forming a part of the jaw a or the position of the
lever c and catch d may be reversed.
The hook i is preferably secured to the clip by rivetting or bolting the base ¹ of
the hook in a recess in the upper end of the main part b as shown so that it can be
easily renewed when broken.
With our improved arrangement as described the clip is more readily attached to
the rope and detached than with existing arrangements and a great saving of time
is therefore effected.
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. In a clip such as described the combination with a lever such as c of a catch
such as operating substantially as and for the purpose described and illustrated in
the accompanying drawings.
2. In a clip such as described the combination with a lever such as c pivotted to
one jaw of the clip of a catch such as d secured to the other jaw operating substan-
tially as and for the purpose described and illustrated in the accompanying
drawings.
3. In a clip such as described the combination with a lever c and catch d of a cam
surface such as h h on the free jaw of the clip substantially as and for the purpose
described and illustrated in the accompanying drawings.

page_text: 4. The combination and arrangement of parts constituting the complete clip
substantially as herein described and illustrated in the accompanying drawings.
