I C'ARL HERMANN OTTO STROHBACH of Leipzig in the Empire of Germany
Manager of New Stadt Theatie do hereby declare the nature of this invention to be
as follows
The object of this invention is to provide a device by which more especially the
end of a rope may be fixed to the standing part to form a loop at the end of a rope
said device being however generally applicable for fixing ropes together
The device consists of a suitable block having a passage through it for the standing
part of the rope and another passage for the return end of the rope
Between the two passages there is operated a screw wedge which Jams the standing
part and the return end respectively in their grooves, so that a secure loop is formed
on the end of the rope There may be inserted between the wedge and the ropes
V shaped spring or piece, the outer sides of which are adapted to hold the ropes
when pressed outward against them by the wedge

page_text: A New or Improved Device for Connecting together Ropes and the
like, More Especially for Use in Forming Loops on Ropes
I CARL HERMANN OITO STROHBACH of Leipzig in the Empire of Germany,
Manager of New Stadt Theatre do hereby declare the nature of this invention and
in whit manner the same is to be performed to be particularly described and
ascertained in and by the following statement
The object of this invention is to provide a lock or fastener for connecting the end
of a rope to the standing part so as to form a loop, it is principally intended for use
with wire ropes where in looping the end the conrecting of the end to the standing
part in a proper and secure manner is usually tedious and difficult operation of
splicing The improved lock is intended to save the time and trouble of this operation
and to form a perfectly secure fastening as strong is the
rope
itself
Reference being made to the accompanying drawings, Fig 1 is a sectional view of
the lock with the rope looped therein, Fig 2 is side view thereof, Fig 3 is a
sectional view showing a slight modification in the lock, Figs 4, 6, and 9 are detail
views of one part of the lock and modifications thereof Fig. 5 7 and 8 are detail
views of another part of the lock and modifications of the same
The lock consists firstly of block a having within it a spice a¹ extending in the
direction of the length of the block, the breadth of the spice in one direction being
somewhat larger than the diameter of the rope and in the other direction of
comparatively large breadth below and tapering gradually towards the other end
where it may be said to end with a breadth equivalent to about twice the diameter of
the rope The said space is open to the outside of the block at this end through a
passage a sufficient to receive the standing part of the rope such passage being
preferably so directed that the rope without undue flexure passes down through the
same and along one of the inclined walls of the space At the base of the block the
space a¹ is open through two passages a³ at each of a diameter somewhat larger than
that of the rope and extending in alignment respectively with the tapering walls of
the space a The standing part, so called, of the rope passes along the one inclined
wall of the space a through the passage as and thence sufficient rope being left to
form a loop the end is passed up through the passage at along the other inclined wall
of the space a¹ to the upper end thereof The ropes thus lying against the inclined
walls respectively will he towards each other and it is obvious that by driving up a
wedge between them they will be jammed outward against the walls and securely held
in the block This may be
a simple wedge as b in Fig 3 and of rectangular cross-
section or with plane faces as shown in Fig 5 or preferably with concave faces as in
Fig 7 or 8 for the better grasp of the wedge on the rope To drive the wedge a
screw threaded hole a' may be made through that end of the block lying between the
passage a² and at the same being of large enough diameter to enable the wedge b to
be passed through it into the space a', a screw threaded bolt d having a square head or

page_text: other suitable means for turning the same is fitted in said hole a* and abuts upɔn the
base of the wedge for driving the same The tapering sides of the space a¹ may
be slightly curved as shown in Fig 3
In place of using a wedge acting direct on the rope a spring wedge cas in Fig 4
6 or 9 may be previously inserted and distended by the wedge b
Such a spring
wedge would maintain a substantially stationary position distending more or less
according to the position of the wedge b On the lower end of one or each of the
limbs of the wedge c may be arranged the reinforce or projection and at a suitable
or corresponding place along the inclined wall or walls of the space a² may be a
corresponding hollowing h (Fig 1)
The construction of the wedge c is visible from figs 4, 6 und 9, it may be a bent
piece of metal or two pieces of metal rivetted together at one end, it may have plane
or concave faces
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
1 A block a having a space a¹ with tapering walls and open for the reception of a
rope or ropes to lie along said tapering walls in combination with a wedge in said
space adapted to Jam said rope or 10pes against said tapering walls for the locking of
said rope or ropes
2 A block a having an interior space a' with tapering walls and passages a³ and a¹
alligned with said walls and adapted to receive a rope or ropes in combination with a
wedge in said space and means for driving said wedge to jam said rope against said
tapering walls
3 A block a having an interior space a¹ with tapering walls, a passage a² alligned
with one of said walls at the tapered end of the space, passages a³ and a* alligned
with said walls at the broad end of the space adapted to receive a looped rope
substantially as described in combination with a wedge in said space and a screw bolt d
bearing on sud wedge for driving the same for the jamming of said rope against
said tapering walls
4 The combination substantially as illustrated and described of a block a having
space a' and passages a³ a³ and a as set forth with a spring wedge c located in said
space, a wedge b adapted to distend said spring wedge and a screw bolt for driving
said wedge b
