Improvements in Apparatus for Removing Knots, Bunches, and the
like from Silk Threads.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention to be as follows:-
This invention relates to apparatus for removing knots, bunches and the like from
silk threads.
The improved apparatus which has been devised with the object of enabling silk
threads of any size to be thoroughly cleaned with economy comprises a double
frame carrying two series of delivering bobbins from which the raw threads are
unwound, cleaners corresponding to the several bobbins, two series of receiving
bobbins upon which the threads are wound after they have been subjected to the
cleaning operation, and other operative parts hereinafter described.
After leaving the delivering bobbin the raw thread passes over a glass rod, which
puts it under the desired tension, to the cleaner. A second glass rod is provided
over which the thread passes next prior to being wound upon the receiving bobbin.
The winding of the thread upon the receiving bobbins is effected in a regular manner
by the action of a rocking lever the oscillations of which determine the extreme
points to which the said thread is wound upon them. This rocking lever can be
actuated by any mechanism adapted for the purpose.
The receiving bobbins which may be made of any suitable material are mounted
upon vertical spindles which receive their movement from an endless belt through
the medium of drums secured upon the aforesaid spindles. These spindles are
provided with collars whereon the bobbins rest.
Through the medium of the endless belt the velocity of the spindles and therefore
that of the receiving bobbins is regulated, the latter being rotated on the one hand
under the action of the above-mentioned collars and on the other hand under that
of the spindles which traverse them. By reason of the play between the spindle
and the bobbin this second action is very slight relatively to the first so that the
receiving bobbin may be considered as turning almost solely under the action of
the collar on its spindle. It will be understood that under these conditions a very
slight resistance offered to the receiving bobbin will be sufficient for stopping its
motion.
Now suppose a raw-thread to be cleaned is wound upon the delivering bobbin
and a knot bunch or the like arrives at the cleaner. At this moment a resistance
offered to the receiving bobbin so that the latter will stop without a shock.
Accordingly there is no tendency either to cause the knot, bunch or the like to pass
the cleaner if it is not too thick or to cause the breakage of the thread if the knot
bunch or the like is too thick for traversing the cleaner.
In the apparatus hitherto employed for cleaning silk threads the receiving
bobbins are slid upon a horizontal spindle and are rotated under the action of the
frictional surface existing between the spindle and the bobbin and extending the.
entire length of the bobbin. Furthermore as is generally the case they are placed
at a slight inclination when they are also rotated under the action of the frictional
surface of the bobbin bearing against the collar which serves as a stop.
Hence it will be understood that in the arrangement heretofore used there is a
much greater frictional surface so that if a knot bunch or the like passes to the

page_text: cleaner the bobbin will continue its movement all the same and the thread will
break or will not be cleaned.
Apparatus have already been used wherein receiving bobbins are arranged
vertically but these bobbins are designed to receive twisted threads after the
twisting operation, which differs entirely from the cleaning of raw threads.
Use has also been made of apparatus wherein the receiving bobbins are arranged
vertically but they serve for reeling the silk which operation has nothing in common
with the operation performed by the apparatus herein before described.
The industrial advantages realized by the improved apparatus are considerable:-
A saving of space is obtained, which enables about three times as many spindles
to be put in the same space.
The work of the operator is facilitated, who can have before him without being
interfered with as many spindles as his day's work may require.
There is less waste, the thread being rarely caused to break and also a saving of
labour as numerous manipulations are dispensed with which are well known by all
the operators, such as are necessary for tying the ends of the thread after each
breakage.
A better quality of silk is obtained (with the same opening of the cleaner) owing
to the complete suppression of all the small knots, bunches and the like, which in
the arrangement heretofore used can pass through the cleaner.
By varying the velocity thick silk threads can be cleaned as well as thin silk
threads.
By the arrangement of a rocking lever provided with a guide rod the incon-
veniences are obviated which result from the passage of the thread through a guide
ring (the latter being here dispensed with) before it is conducted to the receiving
bobbin as is the case in the apparatus hitherto employed.
Owing to the vertical arrangement of the receiving bobbins at the upper part of
the cleaner above the hand of the operator waste of any kind is prevented from
falling upon the receiving bobbins which has heretofore taken place when the latter
have been placed horizontally below the hand of the operator.
An economy is effected in the motive power, as the resistances which occur in
the old apparatus are to a great extent suppressed.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Removing Knots, Bunches, and the
like from Silk Threads.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings in the County of Middlesex, 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 apparatus for removing knots, bunches and the like from
silk threads.
The improved apparatus which has been devised with the object of enabling silk
threads of any size to be thoroughly cleaned with economy, comprises a double
frame carrying two series of delivering bobbins, from which the raw threads are
unwound cleaners corresponding to the several bobbins; two series of receiving
bobbins upon which the threads are wound after they have been subjected to the
cleaning operation, and other operative parts hereinafter described.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.

fdenotes the raw thread which after leaving the delivering bobbin passes over
a glass rod which puts it under the desired tension to the cleaner P. is a glass
rod over which passes the thread prior to being wound upon the receiving bobbin.
The winding of the thread upon the receiving bobbins is effected in a regular
manner by the action of a rocking lever Z, the oscillations of which determine the
extreme points to which the said thread is wound upon them. This rocking lever
can be actuated by any mechanism adapted for the purpose.
B B are bobbins which receive the raw threads after they have been cleaned, they
may be made of any suitable material, and are mounted upon vertical spindles F the
pivot of which is at p and which receive their movement from an endless belt C
through the medium of drums N secured upon the aforesaid spindles. These
spindles are provided with collars e upon which the bobbins B rest.
Through the medium of the endless belt C the velocity of the spindles and
therefore that of the receiving bobbins B is regulated, the latter being turned on
the one hand under the action of the above mentioned collars e and on the other
hand under that of the spindles which traverse them. By reason of the play
between the spindle and the bobbin this second action is very slight relatively to
the first, so that the receiving bobbin B may be considered as turning almost solely
under the action of the collar e on its spindle. It will be understood that under
these conditions a very slight resistance offered to the receiving bobbin B will be
sufficient for stopping its motion.
Now suppose a raw thread to be cleaned is wound upon the delivering bobbin R
and a knot, bunch or the like arrives at the cleaner. At this moment a resistance
is offered to the receiving bobbin so that the latter will stop without a shock.
Accordingly there is no tendency either to cause the knot, bunch or the like to
pass the cleaner if it is not too thick, or to cause the breakage of the thread if the
knot, bunch or the like is too thick for traversing the cleaner.
In the apparatus hitherto employed for cleaning silk threads the receiving bobbins
are slid upon a horizontal spindle, and are turned under the action of the frictional
surface existing between the spindle and the bobbin and extending the entire
length of the bobbin. Furthermore, as is generally the case, they are placed at a
slight inclination when they are also turned under the action of the frictional
surface of the bobbin bearing against the collar which serves as a stop.
Hence it will be understood that in the arrangement heretofore used there is a
much greater frictional surface, so that if a knot, bunch or the like passes to the
cleaner the bobbin will continue its movement all the same, and the thread will
break or will not be cleaned.
Apparatus have already been used wherein receiving bobbins are arranged
vertically but these bobbins are designed to receive twisted threads after the
twisting operation, which differs entirely from the cleaning of raw threads.
Use has also been made of apparatus wherein the receiving bobbins are arranged
vertically, but they serve for reeling the silk, which operation has nothing in
common with the operation performed by the apparatus herein before described.
A great many industrial advantages are realized by the use of the improved
apparatus hereinbefore described, for example, a saving of space is obtained, which
enables about three times as many spindles to be put in the same space.
The work of the operator is facilitated, who can have before him without being
interfered with as many spindles as his day's work may require.
There is less waste, the thread being rarely caused to break and also a saving of
labour as numerous manipulations are dispensed with which are well known by all
the operators such as are necessary for tying the ends of the thread after each
breakage.
A better quality of the silk with the same opening of the cleaner, owing to the

page_text: 'complete suppression of all the small knots, bunches and the like, which in the
arrangement heretofore used can pass through the cleaner.
By varying the velocity thick silk threads can be cleaned as well as thin silk
threads.
By the arrangement of a rocking lever provided with a guide rod the inconveniences
are obviated which result from the passage of the thread through a guide ring (the
latter being here dispensed with) before it is conducted to the receiving bobbin, as
is the case in the apparatus hitherto employed.
Owing to the vertical arrangement of the receiving bobbins at the upper part of
the cleaner, above the hand of the operator, waste of any kind is prevented from
falling upon the receiving bobbins which has heretofore taken place when the latter
have been placed horizontally below the hand of the operator.
Au economy is effected in the motive power, as the resistances which occur in the
old apparatus are to a great extent suppressed.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
First. The herein described apparatus for removing knots, bunches and the like
from silk threads, comprising an arrangement of vertical receiving bobbins B
mounted upon spindles F turning under the action of an endless belt C, the said
spindles being provided with collars e which cause the corresponding receiving
bobbins B to be turned in combination with the rocking lever Z, the rod, the
cleaner P, the rod and the delivering bobbins R, substantially as described and
represented in the drawing.
Second. The arrangement and the combination with the spindle of an operating
drum and a collar for receiving, supporting and turning the receiving bobbin.
