Improvements relating to Apparatus for Testing and Cleaning Cotton
* and other Thread, Chiefly Designed for Use with Reeling or
Spooling Machines.
We, HENRI OFFROY, Manufacturer, and CHARLES PFEIFFER, Spinning-mill director,
both of Boulevard de Strasbourg, 23 Paris France do hereby declare the nature of
this invention to be as follows:-
Our invention relates to a thread-guide for testing cotton or other threads when
winding the same upon spools or forming them into skeins.
The threads proceeding from the spinning mill often present an uneven sectional
area, some parts being thinner or weaker than others. These defects arise from
insufficient twisting, the result being, that in the course of the weaving operation the
threads break at these defective points under the action of the tension to which they
are subjected. This causes a loss of the workman's time who must connect these
threads, this connection which is effected during the operation of weaving presents
inconveniences that would be obviated if the thread proceeding from the spinning
mill were proved at the time when it is wound on spools or formed into skeins.
The object of our invention is to effect this testing of the thread and to utilize the
whole of their length in weaving.
Our improved thread-guide is applied to the reeling machines in spinning for the
production of skeins, and in weaving to the bobbin frame for making warp bobbins as
well as to what are called spooling machines.
This thread guide comprises two vertical jaws the first of which is made integral
with a support which is fixed by means of a screw or otherwise to the reeling machine
or bobbin frame. The second jaw is connected by lugs and a pin to a bent lever
which oscillates upon a pivot and the lower branch of which carries a counterweight.
The position of this weight can be varied at will by hanging it up in one or the other
of a series of notches in the lever according as more or less pressure is to be exerted
between the two jaws.
The joint of the second jaw has for its object to allow this jaw a little play, in order
that it shall be well applied upon the entire width of the first jaw.

page_text: The two jaws are so shaped at their upper extremities as to form a mouth which
facilitates the introduction of the thread between the jaws. A projection on the
second jaw enables the workman to move the same away from the first jaw when
necessary.
The counterweight being placed at a suitable point of the bent lever to provide
between the two jaws the suitable pressure according to the tension which the thread
is to bear in weaving, the thread to be formed into a skein or wound on bobbins is
passed between the jaws; this thread passes in a continuous manner between these jaws.
If a defect presents itself in the thread, say a thin part, or incision or hollow
affecting the resistance of the thread the latter breaks and may then be connected
again. A thread can thus be supplied with which is tested or proved its entire length,
or the weaver proves his thread at his first machine that is to say, in case this is
oasier.
Moreover, this thread guide presents the further advantage of cleaning the thread.
The first jaw is cut out so as to form a hollow in its middle. If the thread presents
knots, these are detached when they encounter the edge of the jaws; those which
have not been removed in the first passage are almost certainly detached when they
encounter the edge formed by the interior hollow.
It is obvious that we may modify the details of construction of our improved thread
guide without departing from the nature of our invention.

Improvements relating to Apparatus for Testing and Cleaning Cotton
and other Thread, Chiefly Designed for Use with Reeling or
Spooling Machines.
We, HENRI OFFROY, Manufacturer, and CHARLES PFEIFFER, Spinning-mill Director,
both of 23 Boulevard Strasbourg Paris, France, 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 :-
Our invention relates to a thread guide for testing cotton or other threads when
winding the same upon spools or forming them into skeins.
The threads proceeding from the spinning mill often present an uneven sectional
area, some parts being thinner or weaker than others. These defects arise from
insufficient twisting, the result being that in the course of the weaving operation,
the threads break at these defective points under the action of the tension to which
they are subjected. This causes a loss of the workman's time who must connect
these threads; this connection which is effected during the operation of weaving
presents inconveniences that would be obviated if the thread proceeding from the
spinning mill were tested at the time when it is wound on the spools or formed into
skeins. The object of our invention is to effect this testing of the thread and to
employ in weaving, threads that have been tested, the whole of their length.
This thread-guide is applied in spinning to reels for forming the thread into skeins
and in weaving, to bobbin frames, for winding the thread on warp bobbins, as well as
to what are known as spooling machines.
This thread-guide is represented in the accompanying drawing.
Figure 1 is a front view.
Figure 2 a side view.
Figure 3 a plan.
Figure 4 is a side view showing the side opposite that represented in Figure 2.
The improved thread-guide comprises a pair of jaws A B. One of these jaws A is
actuated by a counterweight and the other is carried by an arm to which an upward
and downward motion is imparted in such a manner that the two jaws make a small
to-and-fro movement relatively to each other.
In the arrangement shown, the jaw A on the left hand side is carried by a bent
lever D turning upon its pivot c, the lower arm of this lever being provided with
notches d for receiving a counterweight P.
One of the jaws, the jaw B in the drawing, is formed with a hole O, the edges of
which form stops which detach the knots or the like from the thread when the latter
passes between the two jaws.
The jaw B carries upon the surface which is turned towards the reel, and which is
represented apart in Figure 5, two teeth f, g, that serve to limit the upward and

page_text: downward movements of the thread between the jaws; the thread is retained by these
teeth and is thus always kept between the jaws.
The arm of the jaw B has an eye k through which the thread passes on leaving
the jaws. The two jaws A and B are provided at their upper part with diverging lugs
or the like which facilitate the introduction of the thread between the jaws, and at the
same time enable the jaw A to be moved away from the other jaw when necessary.
The counterweight P being placed at a suitable point of the bent lever to provide
between the two jaws the suitable pressure according to the tension which the thread
is to bear in weaving, the thread to be formed into a skein or wound on bobbins is
passed between the jaws; this thread passes in a continuous manner between these
jaws in the direction indicated by the arrow shown in Figures 2, 3 and 4.
If a defect presents itself in the thread, say a thin part or incision or hollow
affecting the resistance of the thread the latter breaks and may then be connected
again.
A thread can thus be supplied which is tested or proved its entire length, or the
weaver proves his thread at his first machine, in case this is easier.
If the thread presents a knot or the like the latter is detached when it encounters
the vertical edge of the jaws or the edge formed by the interior hole O. By reason
of the vertical alternative shifting motion of the jaws A and B in consequence of
the oscillation of the arm Q these knots do not remain between the jaws, but aro
carried away to tlie upper and lower extremities and thrown outside.
The thread which leaves the apparatus is therefore tested with regard to the resistance,
and cleaned or freed from its knots.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it understood
that we claim :-
The reeling or spooling of thread under tension by means of a thread-guide under
adjustable pressure enabling the cotton or other threads to be proved at the time when
they are formed into skeins or wound upon bobbins and to be connected at the defective
parts before these threads are employed in weaving, this thread guide performing
moreover the operation of cleaner and purifier; the apparatus being constructed in
such a manner that to the jaw without a counter weight is imparted a to-and-fro
motion, thereby forcing to the outside of the pressing surface of the jaws the knots
or the like which are being detached from the thread, the latter being kept between
the jaws by upper and lower teeth forming projections upon the surface of the
said jaw.
