PROVISIONAL SPECIFICATION.
Improvements in and connected with Apparatus for the Clearing of
Threads or Yarns of Silk or other Textile Materials.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention,
(a communication to me from Pierre. Perret, of 6 Rue Désirée, Lycns, in the
Republic of France, Manufacturer,) to be as follows:-
The clearing has for its object to rid silk and other threads or yarns of knots,
noil, sluds, lumps, or other impurities, in order to render them fit for weaving.
Apparatus hitherto employed for this purpose, requires constant attention in
order to stop the motion of the thread when a knot, noil, slud or other impurity,
too large or too strong is presented to the parts which should remove them.
The object of the improved apparatus is to render automatic the stoppage of
the thread or yarn which is under these conditions, at the same time continuing the
progress of the others, thereby enabling the operative to superintend a considerably
greater number of threads or yarns and to give them a greater speed. The amount
of work done is thus increased and the causes of breakage and waste are avoided,
which were impossible to prevent in apparatus hitherto in use.
In the accompanying drawings Figs. 1 and 2 show a single set of parts of the
improved clearer acting upon a thread or yarn F delivered from a bobbin, reel or
other apparatus, at V and wound up on a bobbin A carried by a vertical spindle B.
This winding is regulated along the length of the bobbin by the alternating vertical
motion of the bar N obtained by known means.
The clearer P consists of two plates a a of glass or other suitable hard material
fixed to the end of a very light balance pivoted at D and equilibrated by a counter-
poise E. The plates a leave between them a space or slit which decreases in width
from its opening or mouth, and within which the thread or yarn to be cleared enters
to a greater or less distance. This entrance is limited according to the thickness of
the thread or yarn by a bar R, the position of which can be regulated by endless
screws b mounted in its supports
The thread or yarn thus presented to the precise spot where it traverses the clearer
with slight friction, raises the latter immediately a knot, noil or other projecting body
is presented to it; this raising action is utilized in the following manner, not only to
suspend the motion of the winding on bobbin A, but further to slacken the thread in
order to avoid every cause of breakage and enable it to follow the notion of the
bar N which distributes it upon the bobbin A.
The spindle B is supported in a bearing G carried by a rod I sliding horizontally
in the framing and drawn backwards by a spring, see Figs. 1 and 3. When this
spring acts it separates the spindle from the horizontal belt H which gives motion to
it, and therefore stops it. To place it again in motion, it is necessary to press the
button at the end of the rod I and to thus push the spindle against the belt; a stop J
jointed on the framing then falls behind a projection K of the bearing G and holds it
in position. The stop J carries an arm L, upon which is jointed a lightly flexible
finger-piece M, which bears upon an arm C of the clearer, by which it is held raised
and beyond the action of the studs c c on the periphery of the spindle B.
It follows from these arrangements that, when the bobbin A is in motion, a knot,
noil or other projection, will raise the clearer P, the arm C, which is firmly fixed to
t, relieves the finger piece M, which then comes into contact with one of the studs c

page_text: of the spindle in motion; this latter draws with it the finger piece, and with it
the stop J, which rises; the rod I, under the action of its spring, then separates the
spindle from the belt H. The spindle, being no longer driven, gives way to the
reactionary motion of the flexible finger-piece M, and comes backwards, unwinding
a certain length of thread or yarn, which will enable the regulating bar N to
accomplish its movement without breaking or weakening the thread or yarn, the
motion of which is suspended. The operative, warned by the stoppage of the
spindle, can then, quite at his ease, remove the knot, knoil or other projection held
in the clearer and replace the spindle in motion.
It will be understood that the set of parts above described is repeated in parallel
positions on a machine the length of which is only limited by the facility for superin-
tendence. If this machine were employed for treating threads or yarns of different
sizes, the bar R would be divided into several parts capable of separate regulation
and each receiving threads or yarns of the same size.
In lieu of making the clearer a special apparatus as above described, it can be
combined with various machines for winding, reeling, doubling, or effecting other
operations on threads or yarns. For that purpose it is only necessary to place in
the course travelled by the threads or yarns, the two principal parts, the oscillating
clearer P and the bar R which regulates the entrance of the thread or yarn between
the plates a a of the clearer. The oscillating motion of the clearer effected by the
passage of a knot, noil or other projection, being transmitted as above described to
the means for winding the thread, but with arrangements which may be modified
according to circumstances.
Dated this 6th day of June 1896.

Improvements in and connected with Apparatus for the Clearing of
Threads or Yarns of Silk or other Textile Materials.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23 Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention (a
communication to me from Pierre Perret, of 6 Rue Desirée, Lyons, in the Republic
of France, Manufacturer) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
The clearing has for its object to rid silk and other threads or yarns of knots, noil,
sluds, lumps or other impurities, in order to render them fit for weaving.
Apparatus hitherto employed for this purpose, requires constant attention in order
to stop the motion of the thread when a knot, noil, slud, or other impurity, too
large or too strong is presented to the parts which should remove them.
The object of the improved apparatus is to render automatic the stoppage of the
thread or yarn which is under these conditions, at the same time continuing the
progress of the others, thereby enabling the operative to superintend a considerably
greater number of threads or yarns and to give them a greater speed. The amount
of work done is thus increased and the causes of breakage and waste are avoided,
which were impossible to prevent in apparatus hitherto in use.
In the drawings accompanying my Provisional Specification Figures 1 and 2 show
a single set of parts of the improved clearer acting upon a thread or yarn F
delivered from a bobbin, reel or other apparatus, at V and wound up on a bobbin A
carried by a vertical spindle B. This winding is regulated along the length of
the bobbin by the alternating vertical motion of the bar N obtained by known
means.

page_text: The clearer P consists of two plates a. a of glass or other suitable hard material
fixed to the end of a very light balance pivoted at D and equilibrated by a
epunterpoise E. The plates a leave between them a space or slit which decreases in
width from its opening or mouth and within which the thread or yarn to be cleared;:
enters to a greater or less distance.
This entrance is limited according to the thickness of the thread or yarn by a r
bar R, the position of which can be regulated by endless screws b mounted in its.
supports.
The thread or yarn thus presented to the precise spot where it traverses the clearer.
with slight friction, raises the latter immediately a knot, noil or other projecting
body is presented to it; this raising action is utilized in the following manner, not.
only to suspend the motion of the winding on bobbin A, but further to slacken the
thread in order to avoid every cause of breakage and enable it to follow the motion
of the bar N which distributes it upon the bobbin A.
The spindle B is supported in a bearing G carried by a rod I sliding horizontally
in the framing and drawn backwards by a spring, see Figures 1 and 3. When this
spring acts it separates the spindle from the horizontal belt H which gives motion to-
it, and therefore stops it. To place it again in motion, it is necessary to press the
button at the end of the rod I and to thus push the spindle against the belt; a.
stop J jointed on the framing then falls behind a projection K of the bearing G and
holds it in position. The stop J carries an arm L, upon which is jointed a lightly
flexible finger piece M, which bears upon an arm C of the clearer, by which it is.
held raised and beyond the action of the studs c. c on the periphery of the
spindle B.
It follows from these arrangements that, when the bobbin A is in motion, a knot,.
noil or other projection, will raise the clearer P, the arm C, which is firmly fixed to
it, relieves the finger piece M, which then comes into contact with one of the studs c
of the spindle in motion; this latter draws with it the finger piece, and with it the
stop J, which rises; the rod I, under the action of its spring then separates the
spindle from the belt H. The spindle being no longer driven, gives way to
the reactionary motion of the flexible finger piece M, and comes backwards, unwinding
a certain length of thread or yarn, which will enable the regulating bar N to
accomplish its movement without breaking or weakening the thread or yarn, the
motion of which is suspended. The operative, warned by the stoppage of the spindle,
can then, quite at his ease, remove the knot, noil or other projection held in the
clearer and replace the spindle in motion.
It will be understood that the set of parts above described is repeated in parallel.
positions on a machine the length of which is only limited by the facility for
superintendance.
If this machine were employed for treating threads or yarns of different sizes, the
bar R would be divided into several parts capable of separate regulation and each.
receiving threads or yarns of the same size.
In lieu of making the clearer a special apparatus as above described, it can be
combined with various machines for winding, reeling, doubling or effecting other
operations on threads or yarns. For that purpose it is only necessary to place in the
course travelled by the threads or yarns, the two principal parts, the oscillating.
clearer P and the bar R which regulates the entrance of the thread or yarn between
the plates a. a of the clearer. The oscillating motion of the clearer effected by the
passage of a knot, noil or other projection being transmitted as above described to.
the means for winding the thread, but with arrangements which may be modified
according to circumstances.
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 :-
1. An apparatus for the clearing of threads or yarns of silk or other textile-
materials consisting mainly of an equilibrated clearer, arranged so as to be raised.

page_text: without effort by the knots, noil, sluds, lumps or other impurities of the thread or
yarn, and to liberate by this rising a flexible stop apparatus which arrests the thread
or yarn winding on spindle, and by its reaction causes it to be moved backwards,
substantially as herein set forth and for the purpose stated.
2. In an apparatus for the clearing of threads or yarns of silk or other textile
materials of the character herein described, the combination of a clearer having a
tapering slit, and of a movable bar serving to bring the thread or yarn to, and hold
it at, a convenient point so that it may fill the slit of the clearer, substantially as
herein set forth.
3. The improvements in and connected with apparatus for the clearing of threads
or yarns of silk or other textile materials, substantially as herein set forth.
