PROVISIONAL SPECIFICATION.
Improvements in Rope-couplings.
I, BERNHARD KIRSCH, of IX Wæhringerstrasse 59, Vienua, in the Empire of
Austria, Professor, do hereby declare the nature of this invention to be as
follows:-
This invention of improvements in rope-couplings has reference to those parts
of the coupling that are secured to the ends of the ropes or strands and it is
designed to afford means for effecting this connection in a durable and easy manner
without weakening the rope at the parts where it is secured to the coupling and
without putting a too heavy strain on these parts when the rope is made taut.
To afford means for making this connection, the two parts of the coupling are
made in the form of loops traversed by passages crossing each other at right or
other suitable angles, bent towards the end of the loop, and at the same time
twisted axially in such a manner that the ends of the ropes or strands passed into
these passages are free to form loops, and fit accurately all parts of the twisted
surfaces of these passages when, after splicing, the rope is twisted to make
it taut.
In the accompanying drawings, Fig. 1 is a plan and Fig. 2 a side elevation of a
rope-coupling embodying my invention.
As shown, each of the two parts of the coupling which may be united in any
known or suitable way ends in a loop-shaped part L or R in which are two
passages or crossing each other at right angles and intended for receiving
the strands of a rope.
These passages are bent on each side towards the end of the loop-shaped part,
and are besides twisted with relation to the axis of the coupling, to suit the twist
of the strands in the rope.
By this arrangement, the end of each strand, when passed through one of the
passages, can be bent into a loop, and then be spliced, and the strands thus
fastened to the coupling will accurately fit the passages on the rope being twisted.
When the rope is made taut by rotating the two parts of the coupling
relatively to each other, the strands will be twisted to correspond to the twist of
the passages in such a manner that the strands will be constantly guided within
the loop-shaped part of the coupling, the rope being thoroughly twisted flush
with these loop-shaped parts and there being no possibility of any unequal tension
detrimental to the ropes.
For ropes made of a greater number of strands than shown, the number of
passages in the loop-shaped ends of the coupling and the angle at which such
passages cross each other are correspondingly varied.

page_text: I, BERNHARD KIRSCH of 1X, Wæhringerstrasse 59, Vienna, in the Empire of
Austria, Professor, 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 improvements in rope-couplings forming the subject matter of this invention
relate to those parts of the couplings to which the ends of the ropes or strands
are secured; and they are designed to afford means for effecting this connection
in an easy and safe way and so that neither shall the ropes, be weakened at the
parts where they are secured to the coupling nor shall an injurious strain be put
upon them on tightening them up.
To afford means for making a connection of this kind, the two parts of the
coupling are made in the form of loops, being traversed by passages which cross
each other and which are bent towards the ends of the loop-shaped parts and are
also twisted axially in such a manner that the ends of the ropes or strands drawn
through these passages can be bent together so as to form loops, and, after splicing,
will on being laid by the twisting up of the ropes, accurately fit the passages of
the loop-shaped parts throughout the length thereof.
In the accompanying drawings,
Figs. 1 and 2 represent in perspective a coupling according to this invention as
seen from above and from one side respectively.
As shown, each of the two parts of the coupling, which may be connected with
each other in any known or suitable way, ends in a loop-shaped part L or R
provided with two passages 1, l' or r, r' which cross each other and through which
the strands of a rope are intended to be drawn.
These passages are bent at each side towards the outer end of the respective
loop-shaped part and are besides twisted with relation to the axis of the coupling
to a degree corresponding to the twist or lay of the strands in the rope.
By this arrangement, the end of each strand, when drawn through one of the
passages, can be bent into a loop and spliced, and the strauds thus secured will,
on being twisted together, fit accurately into the passages of the loops.
When the ropes are made taut by rotating the two parts of the coupling
relatively to each order, the strands will be twisted together to correspond to the
twist of the passages, so that the strands will be always completely guided in the
loop shaped parts, rendering it possible to thoroughly twist the ropes until they
are tight on the loop-shaped parts and also preventing the strands from being
injured by subjection to unequal tension.
In some cases, particularly when the rope consists of a greater number of strands
than four, for which the arrangement illustrated is designed, the number of loop-
shaped passages in each part of the coupling may be increased.
In some cases it may be advantageous to omit the cross pieces or partitions p
between the passages and so as to form on each part coupling one single
opening as shewn by dotted lines in Fig. 1.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. A rope-coupling comprising two loop-shaped parts Land R each provided
with passages which cross each other, which are beut towards the outer end of the
respective loop-shaped part and are also twisted relatively to the axis thereof,
substantially as herein described for the purpose set forth, whether or not a cross
piece or partition p be left between the said passages.

shown in the accompanying drawings.
