Improvements in and connected with Couplings for Ropes, Cord and
the like.
I, FRANZ PRETZEL, of 32, Grosse Hamburger Strasse, of Berlin, Kingdom of
Prussia, German Empire, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a coupling device for ropes, cord, leather-strips and
the like and has for its object various improvements in the construction of the
same.
Couplings or fastenings of the description hereinafter mentioned are usually
employed to transmit the driving power for machines of almost every kind, the
hitherto employed couplings possessing however the disadvantage that to secure
the parts of the coupling to the rope or cord, screw-threads, pins, rivets, and the
like were employed which methods have been found to be inconvenient, impractic-
able and unsafe.
To obviate these disadvantages is the object of my invention, which I herein-
after describe with reference to the accompanying drawing annexed as part of
this specification.
In the drawing:
Figure 1 is a plan and part section, this figure showing the manner in which
the coupling is secured to the rope or cord.
Figure 2 shows the cord or rope ends secured to the coupling parts.
Proceeding to describe the coupling proper, I remark, that the same consists
of two parts a a', the end of each part or half, being provided with a socket, into
which the cord ends b₁ are entered.
At the opposite or free ends of the said sockets a a¹, are the parts e e¹ pivoted
at cc and provided with a corresponding hook and eye respectively, and also with
the prongs or tapered pointed projections & d'.
The construction of the coupling will be clear from the drawing without
further description.
The modus operandi is as follows:
When the cord ends have been introduced into the sockets, the prongs d
of the lever-like parts e e¹ are caused to pass through the cord end within the
socket, whereby a safe, rapid and convenient connection of the cord-ends is
attained.
If desired the end of each prong after having passed through the cord within
the socket can be slightly riveted over, to prevent the same working loose.

-
I, FRANZ PRETZEL, of 32, Grosse Hamburger Strasse, of Berlin, Kingdom of
Prussia, 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 a coupling device for ropes, cord, leather-strips and
the like and has for its object various improvements in the construction of the
same.
Couplings or fastenings of the description hereinafter mentioned are usually
employed to transmit the driving power for machines of almost every kind, the
hitherto employed couplings possessing however the disadvantage that to secure
the parts of the coupling to the rope or cord, screw-threads, pins, rivets, and the
like were employed which methods have been found to be inconvenient, impractic-
able and unsafe.
To obviate these disadvantages is the object of my invention, which I herein-
after describe with reference to the drawing filed with the Provisional Specifica-
tion, in which drawing:
Figure 1 is a plan and part section, this figure showing the manner in which
the coupling is secured to the rope or cord.
Figure 2 shows the cord or rope ends secured to the coupling parts.
Proceeding to describe the coupling proper, I remark, that the same consists
of two parts a a¹, the end of each part or half, being provided with a socket, into
which the cord ends 6 b₁ are entered.
At the opposite or free ends of the said sockets a a¹, are the parts e e¹ pivoted
at cc and provided with a corresponding hook and eye respectively, and also with
the prongs or tapered pointed projections_d d¹.
The construction of the coupling will be clear from the drawing without
further description.
The modus operandi is as follows:
When the cord ends have been introduced into the sockets, the prongs d d¹
of the lever-like parts e e¹ are caused to pass through the cord end within the
socket, whereby a safe, rapid and convenient connection of the cord-ends is
attained.
If desired the end of each prong after having passed through the cord within
the socket can be slightly riveted over, to prevent the same working loose.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
In a coupling for ropes, cord and the like, sockets (a a¹) into which the rope
or cord ends are entered, in combination with lever-like parts (e e¹), pivoted
at (cc) and provided with a hook and eye respectively, the said parts (e e¹)
having prongs (d) adapted in their open position to permit the cord ends to be
pressed into the sockets and, in their closed position, by passing through the
said cord ends, to securely hold the said cord, as set forth.
Dated this 1st day of July 1899.
