PROVISIONAL SPECIFICATION.
Improved Apparatus for Joining the Ends of Warp and other
Threads.
I FREDERICK THOMASSON of Blackley Mill, Blackley near Manchester in the
County of Lancaster, Manager, do hereby declare the nature of this invention to
be as follows:-
This invention relates to means for joining ends of warps or threads together
and is especially applicable and valuable for making short pattern warps where a
number of webs are required to be joined together and put on one beam, the object
of the invention being to dispense with the present system of "twisting-to," an
operation which requires very skilled expensive labour to perform quickly, and a
special frame, called a "twisting frame," which occupies a considerable space in'
the mill.
The invention consists of a small apparatus by means of which the ends of two
warps can be knotted together and cut, and which I call a "knotter."
The knotter consists of a hook, in form somewhat like a crochet hook, the inside
of the hook being made or provided with a knife-edge or cutter. The hook is
protected by a spring guide forming with the point of the hook a kind of notch for
the purpose hereafter described.
The knotter can be used by hand after the manner of a crochet hook but I
prefer to fix it to a sliding bracket on a convenient frame.
The knot is formed as follows:-The two ends to be joined are brought side by
side together pointing in one direction and slipped round the knotter in such a way
that their free ends are behind the loop or hitch thus formed. These free ends are
then slipped in between the point of the hook and the spring guide and then held
there while the loop or noose is drawn off the knotter. This action will form a
slip knot the loop of which catches the cutter inside the hook and is thereby
severed. A short piece at the free end of each warp is thus cut away and is pulled
out of the knot which however has secured the two warp ends firmly together by a
neat knot and the operation is complete.
This knotter in conjunction with its bracket and frame occupies very little space,
and so little skill is required that child labour or young persons can with this
apparatus do nearly as much work in the same time as the expensive skilled adult
labour hitherto necessary could do.
One great feature of this invention for warps when the frame and bracket are
used, is that the ends are all joined almost in an exact line at a right angle across
the warp, thereby ensuring such an even tension or stretch that when the joined
warps are opened out in opposite directions to form a continuous warp there are
practically no tight and slack ends.
The knots are also so much neater, smaller and more uniform in size than
joins "made in the ordinary way by "twisting-to" that they pass more easily
through the "gears" and reed and thereby save much breakage.
This knotter is also applicable for joining threads together other than warps.

Threads.
I FREDERICK THOMASSON of Blackley Mill, Blackley, near Manchester, in the
County of Lancaster, Manager, 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 means for joining ends of warps or threads together and
is especially applicable and valuable in the making of short pattern warps where a
number of webs are required to be joined together and put on one beam, the object
of the invention being to dispense with the present system of "twisting-to,” an
operation which requires skilled expensive labour to perform quickly, and a special
frame, called a "twisting frame," which occupies a considerable space in the mill.
The invention which will be readily understood on reference to the accompanying
drawings consists of a small apparatus by means of which the ends of two warps
can be knotted together and cut, and which I call a "knotter."
The knotter consists of a hook a in form somewhat like a crochet hook as seen
at Fig. 1, the inside of the hook being made or provided with a knife-edge or
cutter, as seen at a+ on Fig. 2, which shews the point of the hook in section. The
hook is protected by. a spring guide 6 forming with the point at of the hook a kind
of notch (see Fig. 1) for the purpose hereafter described.
The knotter can be used by hand after the manner of a crochet hook, but I
prefer to fix it to a sliding bracket c on a convenient frame c', either on the loom
as shewn at Fig. 3, or separate so that it can lean against a wall d as seen at
Figs. 4 and 5.
The knot is formed as follows:-The two ends e and to be joined are brought
side by side together pointing in one direction, and slipped round the knotter in
such a way that their free ends et f+ are behind the loop or hitch thus formed, as
shewn by the end view Fig. 1^. These free ends are then slipped in between the
point of the hook and the spring guide (see Fig. 24), and then held there while the
loop or noose is drawn off the knotter. This action will form a slip knot, the loop
of which (see Fig. 2) catches the cutter a+ inside the book and is thereby severed,
as seen at Fig. 2B. A short piece at the free end of each warp is thus cut away
and is pulled out of the knot which however has secured the two warp ends firmly
together by a neat knot and the operation is complete. The joined ends are then
looped round a sliding bar g mounted on the frame c'.
This knotter in conjunction with its bracket c and frame e' occupies very little
space, and so little skill is required that child labour, or young persons, can with
this apparatus do nearly as much work in the same time as the expensive skilled
adult labour hitherto necessary could do.
One great feature of this invention, when the frame and bracket are used, is that
the warp ends are all joined in a straight line across the warp, thereby ensuring
such an even tension or stretch that when the joined warps are opened out in
opposite directions to form a continuous warp there are practically no tight and
slack ends.
The knots are also so much neater, smaller and more uniform in size than
"joinings" made in the ordinary way by "twisting-to" that they pass more easily
through the "gears" and reed and thereby save much breakage.
This knotter is also applicable for joining threads together other than warps.

page_text: 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 knotter for joining the ends of warp and other threads constructed substantially.
as hereinbefore described and illustrated by the accompanying drawings.
