thank you very much for your time and research
@alanleeknots
try again - pull simultanously with both ends to the side with the one coil and
use a thinner line to grep a thicker rope or a bundle of two ropes than you must
get a instantly heavy blocking.
Use lines thinner 10 mm.
Thiker ropes may not bend enough.
On the question whether I claim discovery:
In fact, I find it very unlikely that this very simple hitch in the course of the use of ropes in the last 80000 years of mankind hasn't already been used, it's certainly not one of my inventions.
However, there are no practical applications, (e.g. as tautline hitch, "reusable instant CableTie") published available.
( Thrun's hint should come closest to this and probably has it rated for vertical applications. )
By the way: is it possible to get a picture of Thrun's illustration ?
1998 issue of Arborist News , (1973, p. 5)
So far i state:
The geometric form is mentioned,
- with abok, however, with the same geometry and not as knot but only as arbitrary
Reinforcement to be added in a given lashing function .
- And not In its lashing function described by me and as an adjustable double loop
(adjustable double Bowline, Softshakle, tautline etc.).
The knot seams is apparently not detected.
- One coil is contained as a basic element in most simple Knots.
In Purcell (1970) the Prusik is already known as the name for double twist with endless
line (4 turns) ove a rope has been known.
Matter of one CoilA - From the point of view of Prusik users Purcell is a Prusik with an additional
upper turn and therefore asymmetrical, but is specified with its own name.
B - From the point of view of Swabich users Purcell is also a Swabish Hitch with a lower turn more
and as asymmetrical as Swabish Hitch in principle.
but is specified under the name Purcell.
C - If a Knot is not specified with an identifier, it can alternatively be specified based on the
Prusik "point of view" as type Prusik in variant plus/minus one coil
- in the Swabich "point of view" as type Swabish in variant plus/minus one coil
can be described.
In this manner the hitch to be discussed here would be after procedure
A as Prusik minus one lower turn or by procedure and after procedure
B as Swabish stitch minus one upper turn.
So I think also one coil manners to see another but not a new Knot;
Also as various descriptions according to type A and type B suggest, an additional coil influences
very strong the mode of action e.g. to increased safety or increased or reduced friction
and may have developed into a name specification with a group of coils.
As In Dan_Lehman's post mentioned sources i read:
" Thrun illustrated a "Prusik knot with an odd number of coils" (1973, p. 5), and his
description of how to tie, use, and adjust this knot agrees perfectly
with the Schwabisch.
In On Rope, Smith and Padgett show a Prusik tied with three,
four, and five coils, "
The consideration of the characteristics of the variants of Prusik and asymmetrical Swabish hitch
seems to play in the vertical environment where a hanging rope is found
and high safety is needed; additional coils should bring advantages, while the
friction nodes (Tautline Hitch ) in a non-vertical environment can manage with fewer turns
can.
A specification or description by name as a node seems to be open
til yet although there is a high practical and daily variety of uses as
http://www.pallastek.de want to show.
The knot to be discussed here, with quickly laid turns, is excellently suited
for countless applications in workshop, household, outdoor and maritime environments.
And contrary to the statement of Thrun the knot can not only produced with a line Part
but rather, for example, from a cove or sling and stick it onto objects/bundles or
use it as a terminal node on a tautline by inside-out conversion
and use it as an instant cabletie that ties as fast as a shoelace.
Examples See website above.
