COMPLETE SPECIFICATION.
An Improved Wire Cable Coupling-device for Car- or Trolley-
cables and the like.
I, ADAM KAISER, of Cassel, in the Province of Hesse-Nassau, German Empire,
Manufacturer, 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 improved wire cable coupling-device for car- or trolley
wire-cables and the like, and has for its object to produce a coupling, by means of
which, wire cables, or more precisely, the ends of such cables may be connected in an
easy, rapid and convenient manner, but also in a manner possessing a very high
degree of safety.
My improved device is shown in the accompanying drawing, in which :
Figure 1 illustrates my coupling, when employed to connect two wire cable-ends,
said cable being composed or consisting of 19 wire-strands.
Figure 2 shows a vertical section through the line A-B.
Figure 3 represents a coupling according to my invention adaptable for cable
ends, where a shackle is employed.
Proceeding to describe the coupling, the same is as hereinbefore indicated,
especially adapted for connecting the two ends of wire cables for car- or trolley-
cables. The characteristic feature of the new coupling is, that the separate wire-
strands are secured or fastened in such manner, that the higher tension exerted upon
and by the inner strands n serves to hold and bind in proper position the outer
strands o the said outer strands as indicated, having a lower tension within the
coupling.
The coupling proper, as shown more especially in Figure 1, consists of two conical
sockets or casings (a a¹), further of a middle cylindrical casing or socket (b), and
lastly, of pressure-rings (c c¹).
The coupling is attached to the cable ends in the following manner:
Firstly the casing or conical socket (a or a¹) is placed upon one end of the said
cable, then the outer strands (o) of the said end of the cable are bent over and
within the casing and subsequently cut to a suitable length.
Hereupon the pressure-ring (c) in a hot or cold state is forced over the inner wire-
strands, which are then bent over it.
The opposite cable end is now treated in exactly the same manner as herein
before described with reference to the first end of the cable, whereupon the middle
portion of the coupling, .e. the middle casing or socket (b) is screwed over the two
before mentioned conical sockets or casings (a a') which hold the separate cable
ends.
The said middle-casing or socket is subsequently secured into position by the
employment of small pins (i il, Figure 1-3) for the purpose of preventing the said
casing or socket (b) from again turning or becoming loose upon the conical sockets
or casings (a a¹).
When adapting my improved coupling for the purpose of attaching a shackle to
the cable end, the aforesaid middle-casing or socket (b) possesses a special and

page_text: corresponding shape, as requisite for such cases.
is shown in Figure 3 of the drawing.
This modification of my coupling
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 :—
A coupling-device for wire cables, characterised by the employment of a pressure-
ring (or rings) c c¹ being forced or pressed upon the inner strands of the cable, which
inner strands are subsequently bent over the pressure-ring or rings, and in which
coupling-device, the said inner strands, (in consequence of their higher tension),
securely hold or bind the outer strands in position, substantially as described.
