Improvements in Rope Clips.
I, MAX EICHLER, of the Alt Zscherben Mine, near Nietleben, in the Province-
of Saxony Head Miner, 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 to an automatic clip for round ropes, for use with either
continuously driven or periodically driven travelling wire ropes. A clip, designed
according to this invention is illustrated in the accompanying drawing in which
Figure 1 is a side elevation of the same. Figure 2 is a section on the line of
Figure 1 the clip being shown open, and Figure 3 is a similar section showing the
clip in its closed position.
The object of the whole apparatus is to enable the load which is carried to be
automatically thrown into and out of engagement with the rope in the case of
continuously or periodically driven wire ropes. This object is effected by means
of a strap, which is arranged so that it can be turned into various positions by
stops which are situated in its path, with the result of pressing together or
opening the jaws of the clip, which jaws in their turn serve to grip the rope
between them.
C,
The travelling rope a (Figure 1) is gripped by two gripping jaws b and
which
are connected together like a pair of tongs by means of a screw d, and which are
formed at the gripping place and also in the portion surrounded by the strap of
segmental form in cross section as shown in Figures 2 and 3. One of these two.
gripping jaws bis prolonged at its lower end so as to form a cylindrical part
having a screw-threaded extension for the purpose of enabling connection to be
made with the car or wagon in an easy and rapid manner by means of a cross piece.
For the purpose of avoiding lateral shifting of the gripping jaws when the strap e-
is rotated a screwbolt fis screwed into b and projects unthreaded and of smaller
diameter into a hole in c. At the place where the strap e embraces the gripping:
jaws the latter are provided with ribs which correspond respectively to grooves in
the interior of the strap. The gripping jaws are made of good wrought iron or of
cast iron, whilst the strap e is made of toughened cast metal. The strap has two
noses el cast on it so that the head of the screw bolt prevents it turning through.
more than an angle of 90°. The hole in the strap e is not made in the form of an
ellipse but has the form of two circles which partly overlap each other.
purpose of enabling one and the same clip to be employed with ropes of different
diameters, plates are employed which can be screwed on at the place where the
gripping jaws clip the rope a.
For the
The automatic opening and closing of the jaws is effected in the following
manner.
The wagon when loaded by the filler is pushed forward so that the strap e
touches a stop fixed at a proper distance from and at the side of the travelling rope,.
the rope entering the space between the two gripping jaws. As the wagon-way
has a certain amount of fall the wagon with the clip and the strap has moved.
forward to some extent, so that the strap e strikes against the stop arranged on the
right hand side and turns clockwise until it slips off the stop. It thus makes a
movement of 90° and acts by means of its smaller diameter of bore to press the
gripping jaws 6 and e towards each other; the wagon is then drawn along by the

place, which stop is arranged on the left hand side, and which acts to turn the
strap e back again counter-clockwise. By this means the larger diameter of the
hole in the strap e' comes into operation; the gripping jaws move apart again, and
the travelling rope is released. The return of the jaws into their initial position
is effected by means of springs h arranged between the two gripping jaws. This
apparatus may be employed either with continuously-driven or periodically-driven
travelling wire ropes, either above ground or in underground mining operations,
with or without gradients and curves. These clips may also be advantageously
employed for suspended or aerial ropeways.
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-
1. An automatic clip for round ropes, characterised by the arrangement of an
ovally-bored strap e which when rotated by striking against external stops situated
in its path acts to release or press together the segmentally shaped gripping jaws b
and c, so as to allow of the wagons being coupled to or released from the rope at
any desired point.
2. A form of construction of the rope clip specified in Claim 1, characterised by
two jaws (which are connected together in tongs-fashion) segmentally shaped in
cross section, with a guiding hoop or strap, which grip or release the travelling-rope
according to their distance apart at the time..
