PROVISIONAL SPECIFICATION.
Improvements in Couplings for Wire Ropes.
We, CARL AGTIIE, Engineer, and the COMPANY "ALLGEMEINE ELEKTRI-
CITATS-GESELLSCHAFT," both of No. 22, Schiffbauer Damm, Berlin, Prussia, do
hereby declare the nature of this invention to be as follows:-
The subject of this invention is a coupling for connecting wire ropes, applicable
to ropes of various sectional forms. The same consists in a sleeve corresponding
to the size of the ropes and increasing in width from its ends towards the middle,
and in two tapering plugs on to which the ends of the ropes are forced while being
inserted into the sleeve, the said plugs causing the rope-cuds to become expanded
and to be wedged against the walls of the sleeve.
.
If the ropes are designed to serve as electrical conductors, soldering metal may
be run in between the ropes and the sleeve through holes provided for in the latter.
Care must, however, be taken not to solder the plugs together. For this purpose
any suitable material not adapted to combine with, or to be destroyed by the solder,
may be brought in between the plugs.

We, CARL AGTHE, Engineer, and the COMPANY "ALLGEMEINE ELEKTRI-
CITATS-GESELLSCHAFT both of No. 22, Schiffbaner Damm, Berlin, Prussia, 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 subject of this invention is a coupling for connecting wire ropes, applicable
to ropes of various sectional forms. The same consists in a sleeve of metal or other
suitable material corresponding to the form and size of the ropes and increasing in
width from the ends towards the middle, and in two tapering plugs on to which the
ends of the ropes are forced while being inserted into the sleeve.
In the annexed drawing
Fig. 1 is a sectional view of the coupling applied to two round ropes c c.
Figs. 2 and 3 are transverse sectional views taken respectively across the end of
the sleeve a and through the centre of the same.
Figs. 4 and 5 are outside views of the sleeve and the plugs b b.
The sleeve a is made at its ends of such inside diameter as just to allow the rope
to pass in, while its diameter in the middle is larger, so that the sleeve tapers from
the middle towards its ends. To the plugs b, which have about half the length of
When the
the sleeve, a like taper is given as to the two halves of the latter.
coupling is to be applied, the plugs are placed in the sleeve with their thick ends in
juxtaposition, and, after the central wire or the core of the ropes has been removed
from the ends thereof upon a length equal to the length of the plugs, in view of
facilitating the introduction of the plugs, both rope-ends are pushed from opposite
sides into the sleeve and forced upon the plugs so as to become expanded. If the
ropes are then drawn upon, the traction will cause the rope-ends to be wedged
against the walls of the sleeve, whereby they are prevented from separating.
In case the ropes are designed to serve as conductors of clectricity, the contact

page_text: produced between the wires and the sleeve is ordinarily sufficient to ensure a good
conduction of the current., But the contact may be improved by means of soldering-
metal run in between the sleeve and the ropes through holes d d in the former.
For obvious reasons care must, however, be taken not to solder the plugs together.
For this purpose plaster of Paris, asbestos-paper, or other material not apt to unite
with, or to be destroyed by the solder, may be brought in between the plugs.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
A coupling for wire ropes consisting in the combination, with the two rope-ends
to be connected, of a sleeve having inside at its ends the size and form of the ropes
and increasing in width towards the middle, and two plugs on to which the rope-
ends are forced within the said sleeve, substantially as described.
