K. Laros Silk Company, Bethlehem, Pa., a corpo ration of Pennsylvania Application August 25, 1936, Serial No. 97,743 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 ment. 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- ‘ tions. The drawing discloses a preferred embodiment of my thread-cleaning attachment shown as 30 having an angular frame conveniently mounted on beam ‘iv by means of an angle bracket 20 secured to said beam and to the rear wall 2! of the frame, to position frame walls 22 and 23 in outwardly projecting spaced parallel relation, 35 wall 22 having a slotted bearing 24 and wall 23 an alined bearing aperture 25 to mount a clean ing brush 26 intermediate the reel 5 and spindle l2 so as to lie in the path of travel of the thread end I5. _ . others that will later herein appear, my inven In the construction shown, I prefer to employ tion comprises the improved thread-cleaning at a separate frame and individual brush 26 for each spindle‘ of the machine, and I have shown the frame walls 22 and 23 as overhanging a shaft 29 mounted lengthwise of the machine and driven in any convenient manner, not shown; said shaft having a series of rollers 30 spacedly positioned tachment now to be more fully described in con nection with the accompanying drawing, and the novel features of which are speci?cally set forth in the appended claims. Fig. l is a diagrammatic sectional elevation of certain essential parts of a usual winding mech anism having a preferred embodiment of my improved thread-cleaning attachment applied thereto. Fig. 2 is a partial plan view corresponding with the showing in Fig. 1. 55 Fig. 3 shows separately, and on an enlarged 40 therealong, each roller frictionally rotating its respective brush 26 by engagement with roller 21 on said brush axle 28. 50 Thus far it will be understood that Wheels 9 will drive the spindles l2 to wind the thread ends i 5 as drawn from the reels 5; and that rollers 36 will engage rollers 2'! to rotate the brushes 65 2 2,065,991 26 lying in the path of travel of the thread ' tion as specifically, de?ned in the following claims.

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 .55 of 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 particular construction shown and above described may be modi?ed within the spirit of my invenr an interposed thread-cleaning mechanism com-._ prising a ?xed carrying frame, a rotary brush movably -mounted ‘therein and having a bristle surface normally, operative upon a passing thread, a friction drive shaft for said brush, and a stop lever normally supported by the passingthread but adapted to“ disengage the frictionally driven brush upon breakage of the thread. 4.
