CO1 HOLDER FOR WINDING MACHINES.
Application tiled Hay 25,
This invention relates to improvements 1n cop-holders for winding machlnes for winding cops, cones or packages of yarn, thread and other textilematerla The invention relates particularly t0 means for rotatably mounting a core or holder to adapt it to bedriven fromk a friction drive-rollor drum to wind the strand material thereon.
One object of the improvement is to provide friction-reducing bearings for the copholder to adapt it to rotate at hi h speed with a minimum of resistance to t e drive.
Another object of the improvement is to provide bearings of the oillesstype for the co -holder to avoid the use of lubricant lia le to .drip or to be thrown on to the material being wound.
Another object of the improvement is to provide bearing means for thecop-holder which are simp ein construction,'econom1cal to manufacture and of maximum durability over long periods of use. Further objects of the improvement are set forth in the following specification' which describes a preferred vform of construction of the invention as illustrated in the accompanying drawings. I'n the drawings:`
Fig. 1 is a part sectional view showing my improved co -holder as embodied 1n wooden or er cone or core mounted to .rotate on a dead-spindle and carryin `a.
conical cop or package driven from a cy indrical drum or drive-roll; and
Fig. 2 is a .similar view of the cone-holder and its mounting showing the bearings therefor in section.
In the present specification I have referred to describe m improved cop-ho der as adapted for win ing conical cops cnaI wooden or ber core or support, but itis to be understood that the core may take other forms and be constructed of any suitable material. 4
In friction or drum-driven winding Inachines the cop or package is'usually wound on a core or holder'which is rotatably mount: ed on a dead-spindle and adapted to be ldriven through surface contact of the winding with a rotatin drum or drive-roll. 'As herein shown the ead-spindle 2 is swiveled at thc end of an arm 3 and is normall held in inclined relation with respect to t e periphery of the. drive-roll 4. The arm 3 may be suitably arranged to adapt the cop-holder lless diameter. The larger bushings 10 so as 1927. serial No. 194,169.
`purpose and in other instances wooden, compositlon or fiber cores or mandrels are employed.
As herein illustrated thecop-holder 5 consists of a substantially solid, conical core or mandrel which may be constructed of hard wood, composition, fiber or any other suitable materia. The core or holder 5. is provided with an substantially throughout its length an terminating at the apex end in a bore 7 of bore 6 is adapted to receive the bearings 10 forrotatably supporting the core or holder 5 on the dead?,
In accordance with the present im rovement the bearings 10 are constructed 1n the form of cylindrical sleeves or bushings made from wood or fiber impregnated with graphite or other similar lubricant. This type of bearing is well .known in various arts as an oilless bearing and possessesV maximum wearing qualities without requiring lubrlcation. It will be noted from Fig. 2 of the drawlngs that the dead-spindle 2 is formed at one end vwith an providing an abutment or square shoulder 12 against which one of the bushings 10 bears. The two bushings 10 are spaced apart by a cylindrical sleeve 15 extending tween their ends-and enclosing the spindle 2 with a free fit. The sleeve 15 is of less outside diameter than the bearing-sleeves or to clear the interior `of the bore 6 of the cop-holder'or core 5. The outer 'sleeve or bushing 10 is held in lace by a flat washer 16 maintained in osition on the spindle 2 by means of a`sp 't wire ring 17fsprungyinto a peripheral groove 18 cut in the surface -of the spindle.
The co -holder or core 5 has its larger bore 6 o suitable diameter to adapt it to slide over the two bearings 10 and the outer end of the spindle 2 rojects through its smaller bore 7 with a alli) ht clearance therearound. The core or holder 5 may be held in place on its bearings by any .suitable axial bore 6 extending y enlarged shank or butt 11 purpose. Referring particularly to Fig. 2
of the drawings, the latch l is pivotally mounted in a slot at the end of the spindle 2 by means of a-cross-pin 21 extending through the sides thereof.v A plunger-pin 23 slides in an axial bore 24 in the end of the spindle 2 and is pressed outwardly by means of a helical spring 25. When the latch 20 is swung into open positionas illustrated in Fig. 2 to permit the core or holder 5 to beslid into place on its bearings 10 the plunger 23 impinges against the fiat inner end of the latch 2O to hold it in this position. Tolsecu're the `core or holdery 5` in place on the spindle 2 the latch 20 is4 rocked into the position shown in Fig. 1, the plunger 23 being thereby retracted to slide across the end of the latch and engage with its side to hold itin this position.
It willbe observed that the present invenl tion provides an extremely simple and eilicient meansfor rotatably mounting a copholder on a dead-spindle. The dev1ce comprises only three main elements in addition to the spindle itself, namely, the -two bearing-bushings of oilless type and the lseparating sleeve. These elements are economical to manufacture or to purchase as merchantable articles and their assembling or mounting on the spindle requires very little machine work.
The complete device provides a mounting which requires no lubrication so that the danger of oil dripping or being thrown and spattered on the yarn, thread or other textile material constituting the cop or package .is eliminated. fIt will be understood lthat copholders of the present type must rotate at high speed and the present form -of bearing-support is practically Ap roof against frictionand wear or deterioration from such high speed operation. I t is'to be further` noted that while I have illus'-` trated the improved device as serving asa support ormounting for a particular type lof cop-holder, lit is also adapted for other forms of cores or cop-tubes. It is also to be understood that whlle I have herein illusfriction-reducing material rotatable on the` spindle, and means for retaining the bushing in place onY the spindle to adapt it to be received within the bore of the cop-holder to rotatably support the latter.
2. A device of the type specified com- `prising a spindle, bushings -constructed of lubricant-impregnated material rotatably mounted on the spindle,`a cop-holder having a bore adapting it to slide over the bushings to be rotatably supported thereby, and means for retaining the cop-holder in place longitudinally of the spindle. Y
3. A device of the tvpe specified cmprising a spindle, a pair of bushings constructed of lubricant-impregnatedmaterial rotatably mounted on the spindle, a sleeve surrounding the spindle and extending between the bushings to hold them in spaced relation,-
and meansv for holding the bushings in position' longitudinally ofthe spindle. 4. A device of the type specified comprising a dead-spindle projecting from a shank forming a shoulder at one end, a plurality of bushings of lubricant-impregnated material rotatably mounted on the spindle with one of them abutting the shoulder at its end, a sleeve enclosing the spindle and extending between the bushings to maintainl them in spaced relation, a Washer abuttinff the endA of the outer bushing, and means or securing the washer o n the spindle to retain the bushings in place longitudinally thereof.
