Abok reference for C.R Smith's weaver's knot

[louis3d]

Hi all,
I sometimes use the knot drawn on fig.1 here http://patentimages.storage.googleapis.com/pages/US2804676-0.png as a bend. I is clearly related to the sheet bend Abok#1.

It seems both strong and secure to me, but I can't find it in Abok. Does anyone know how it is called, and wether yes or no it can be found in Abok ?

Thanks,

Louis

It looks like a Lapp Knot to me:

Thanks a lot, that's it.
So it's a knot Ashley skipped according to other related topics.

Roo has answered this in the way most folks
aware of popular literature should; whether
there lurks some older information yet to be
learned, remains unknown.  (And a read of the
patent might suggest that their search of extant
knots was not so good.

To some degree, this knot is presented in the mass
of stuff --poorly organized, more poorly described--
in the Encyclopedia of Knots & Fancy Rope Work
by Graumont & Hensel ("Hansel & Gretel's make believe")
at p.31pl.8#166 : the ends are shown seized, and a toggle
is run through the knot center (to prevent jamming?).
This, they describe as "the sheet bend with toggle"
which shows that they managed to botch the image
or ... --one can't really know what was going on!
And, of course, things in Hansel&Gretel's world book
of stuff show up all over : p.597pl.318#16 arguably
presents the knot as a hitch to a doubled bight,
and allegedly of old angling interest.

BUT, I don't find this (minimal form of the) knot
all so secure.  For a surer --much more secure
when slack, against loosening by jostling/shaking--
knot, make a full wrap and tuck of the right side's
(in your image --of the line hitching to the bight)
end.  One might call such knots the "double / treble
/... <multiple>" Lapp bends .  And to loosen such
a knot, use the bight's tail to pry back through
the wraps some material of the hitching SPart,
and thereby work the knot loose.  (I can imagine
that in some materials taking a lot of force, this
might be a challenging proposition; sometimes
one needs to do a little work so that the bight
tail can be pulled open with effect.)

Now, I'm curious about the associated patent (1955).

Thanks,

You need not be curious very long. The US patent 2804676 is easy to find, and the purpose is explained there.

It seems as the major virtue of the knot, apart from easily tied, is that it can also easily be untied in the fabric, so that it won't form a lump in the weave.
