5 Claims.
This invention relates to thread winding mech
anism, and more particularly to a thread-clean
ing attachment therefor adapted to remove from
the winding thread all loose ends and waste
5 which may be found clinging thereto.
Raw silk is ordinarily furnished in hanks or
skeins which must be wound in known manner
on a spindle or bobbin for more convenient
handling. It has been found in present day con
ditions that there is a considerable amount of
loose waste lying in the thread, clinging there
to, or attached loosely to a single end, and this
waste makes the throwing operation diificult and
complex because it is extremely di?cult to re
move. Ordinarily impact or friction types of
cleaners consisting of metal plates with narrow
openings will hold waste only for a short time
which varies from a few seconds to several hours,
with no rule to predetermine it, and with or
20 dinary inspection and attention of an operator,
a great deal of waste will pass through the metal
plate and be wound on the spindle, resulting in
an inferior quality of wound thread to later
cause trouble and defects in using. Felt has
been used, alone, or in connection with the afore
said metal cleaner, but waste will eventually pass
through to the spindle. Double metal plates have
been tried, as well as stationary brushes of vary
ing kinds, but with uncertain and generally un
30 satisfactory results.
The primary objects of my present improve
ments are to provide a cleaner that will adequate
ly and positively remove all clinging ends, waste,
and the like, with a minimum strain upon the
main thread, will collect and hold the waste and
prevent it from passing to the spindle with the
running end, and will, in case a break does oc
cur, hold the broken end of the main thread con
veniently accessible for quickly retying to re
40 sume winding.
With the above objects outlined, and with
(Cl. 28-65)
scale, an end elevation of my cleaning attach
Fig. 4 is awfragmentary front elevation of the
attachment as shown in Fig. 3.
Referring to the drawing, the parts of a usual 5
winding mechanism shown as suliicient to fully
describe my improved thread-cleaning attach
ment, are a thread supply reel 5, hung to freely
turn in supporting arms 6; a frame beam 1 ex
tending lengthwise of the machine; main drive 10
shaft 8 having a drive wheel 9 frictionally en
gaging a wheel ill on shaft H which is adapted
to carry a removable spindle or spool I2 to wind
ingly receive the thread end; and a longitudinally
reciprocated traverse rail l3v having a thread 15
guide eye M to- lay the winding thread equally
lengthwise of the spindle.
‘The frictionally
driven spindle ii.’ winds the thread end l5 as
drawn from the reel 5 in a manner well known
and readily understood; and it will be understood 20
that the complete winding machine consists of a
series of reels and spindles, spaced lengthwise
along the beam ‘i and each individually driven
by a corresponding series of drive wheels 9 for
economical multiple operation as heretofore. In 25
stead of the reel 5, the thread supply may be in
the form of a spool or cop for rewinding opera- ‘

of my thread-cleaning attachment shown as 30

To provide against the main thread breaking thread.
3. In a thread-winding mechanism comprising
by removal of such clinging or partly attached thread-supplying
means and a winding spindle,
waste ends, or from other causes, and to prevent
25 loss of the main thread by undesired and wasteful
vwinding of the broken end on said cleaning brush,
I have‘ indicated a brush stopping device which
may simply consist of the bell-crank lever 32,
shown as'pivoted at 33 to frame wall 22 with one
arm 34 lying under the extended end of brush axle
28, and its other arm 35 suitably weighted at 38
as shown, extending upwardly at an angle ,and
' carrying a feeler rod 31 overlying the brush and
adapted to ride upon the passing thread-end I5.
35 Breaking of the thread-end l5 causes the weighted
arm 35 to swing said bell-crank 32 and cause arm
, '34 thereof to engage brush axle 2B and tilt the
latter sufficiently to disengage contact of roller
21 with shaft roller 30, a stop pin 38 limiting such
40 lever lifting swing. The broken thread-end is
held on the brush where it may be conveniently
reached to retie to the thread-end extending from
the spindle for resumption of winding. The
brush 26 is readily removed for cleaning by fur-‘
ther tilting to lift axle 28 upwardly in slot 24;
spindles I0 are removed and replaced as hereto
fore; and'the silk hanks are spread upon reels 5
in well-known manner.
From vthe foregoing description it is "believed
the nature'of my improvements will be readily
so understood and also their effective action in clean
ing the thread-end of all clinging matter, wind
ing and holding such removedvmatter from escape
vto the winding spindle, and convenient holding
'a ‘broken thread-end for quickly retying to

restore the winding operation. The invention
.may obviously be applied to-winding mechanism
employing different thread supplying means,
which means may cause one or a plurality of
60 threads to contact each cleaning brush, and the
