This invention relates particularly to yarn carriers and supports for yarn carriers. Io illustrate some of the uses :to which' the 1n- -vention may be practically applied, attention may be called to Patent llo. 1,267,-

977, granted yto me Aon May 23, 1913, for

a machine for rewindingfbobbins to iorm cross-wound yarn masses commonly termed cheeses, and Patents Nos. 1,274,387 and 1,- 274,42, both dated August 6, 1918, disclosing a warper creel in which the cheeses may be mounted 'for rewindingupon a section beam. In the patents referred to, the crosswound vai'n mat-'sis built `upon a tubular core.A `While the yarn mass is'being rformed, the core is supported upona hub or roller which is mounted upon ball bearings carried by pivotcd arm of the Winder. (For an illustration of such Aa core-supporting roller, reference may be ymade to'Patent'No.' 1,- 329,504 issued February 3,1920.)

llVhile the cheese is being rewound upon lthe section beam, it is supported upon Aa spindle ot a so-called trident, the'trident consisting of a base haii'ing three spindles, each spindle carryinga series oi ball-bearing-rollers for supporting the cheese cores.

The object of the present invention, generally stated, is to improve upon the constructions shown in the patents alluded to, this object being attained by combining the cheese core with a support adapted to be mounted upon either the winder or' the ltrident.

In the accompanying drawings,'Figure 1 is a fragmental view of a trident showing two cheesesmounted thereon, the trident being in the position which it occupies when receiving cheeses at the Winder. Fig. 2v is a tragmental view ot'a trident in theposition which it occupies in the warper creel. Fig. 3 is a sectional view showing the cheese core in operative position upon the arm of one. ot the winding units of the Winder. Fig'. l is an end view of the cheese bearing of the Winder. `5 is an enlarged frag- 'mentafl sectional View.

In the drawings, A indicates a cheese consisting of yarn spirally wound upon the periphery` of a headless cylindrical` yarn carrier. The yarn carrier may be said to consist of two sections, namely, a `tubular Vor sleeve-like supporting member B (Fig. and vroller or cheese core B2 mounted upon the member B, ball bearings being 4interposed-between the elements B and'Bg. In the 'embodiment which I haveselected for illustrationV herein, the supporting member B consists of an inner sleeve 1 having-wa smooth inner surface and adapted to vtit upon a spindlewY onvthe cheese-supporting arm rc oi 4the winder and .upon a spindle'y'fof the trident y. Surrounding the sleeve 1 are two cones 2 and 3 for. the bearings of the roller B, and-an'intermediate spacer sleevet. The parts 2,-'3 and d are rigidly secured tothe sleeve k1 lin any suitable manner, as, for example, byv expanding one end of the-sleeve 1 as at, 5,1and by turning a nut '6* upon the opposite end of the sleeve 1, said nut having a conical surface to en gage the cone 2. r

The cheese core B2 is formed of two -meta'l sections '7 and 8 rigidly' secured vtogether in a suitablemanner. l In the present embodiment ot theinvention, one end of the sec'- tion 7 is reduced vin diameter to tit tightly within one end ot the section 8. VEach of the sections 7 and18 has an inwardly-extending annular end wall 9 and 10, respectively. The inner portionof each lof said` walls is termed to provide a ball race 11.` Between the c'ones'2 vand 3 and the ball races 11 are interposed bearing balls 12. A tubeo'r sleeve 13 extends ybetween the end walls 9 and 10 adjacent to the 'ball bearings. A In the ends oi the tube 13'are small openings Piter aV The ball i `purpose to 'appear hereinafter. racesiare extended to orm lips 15 surrounding the sleeve 4. f

In foi-der to lubricate the .ball bearings, a i

Ythem and get onto the yarn which is wound upon thefcheeseY core. To" prevent vthisy isi one ot' the unctionsof the sleeve 13, the notches lei permitting Va limited amount of oil to pass. The lip llincreases the distance the oil mustcreep and thus Lassists to reduce to the `desiredefrtent the amount ofoil that reaches the bearings.

lVhen the supply of oil requires renewal, the nut 6 is unscrewed and the bearings taken apart by disassembling lthe cones 2 and 3 and the sleeve 4. 011e end of t-he cheese core is then closed by inserting a cork into the annular lip 15, after which oil is poured into the space between said lip and the sleeve 13, the oil flowing through the notches 14 into the interior of the cheese core.

The interior of the yarn carrier element 7. constitutes a chamber to contain oil, and the notched sleeves 13 forms means to restrict the passage of oil from said chamber to the ball bearings.

At each end of the combined cheese core Y and supporting member is means for cushioning the fall of the device when dropped upon a trident spindle. The means herein shown for this purpose comprises a diaphragm or disk 16 formed integral with the outer end of the cone 2 and lying within a depression 9'rl in the end wall 9. A gener ally similar' diaphragm 17 is formed upon the outer end of'the cone 3 and lies within a depression a in the end wall 10.

The means for releasably locking the supporting member B upon the cheese arm of the Winder may partake of Various forms. In the present instance the cheese arm is provided with a generallycylindrical shell or housing 18 surrounding the base of the spindle m, said housing having an end wall 19. In the peripheral wall of the housing 18 are two diametrically opposite openings. Locking balls 2() project partially through these openings, being held pressed against the. walls of the openings by asemicircular leaf spring 21. Rigidly secured to the diaphragm 17 is a ring 22 adapted to encircle the housing 18, said ring having an inturned annular flange 23 fitting slidably upon said housing and adapted to be engaged by the balls 20, as shown in Fig. 3. It will be seen that the combined cheese core and supporting member may be latched in operative position upon the cheese arm by slipping the combined device onto the spindle x and forcing the flange V23 past the balls 20. When thel cheese is to be removed from the Winder, the operator takes hold of the cheese and pulls it off the cheese arm, the balls 20 yielding to allow the flange 23 to pass.

In order to prevent or lessen the possibility of yarn being accidentally wound around the ring` 22 or getting between said ring and the housing 18, there is fixed to the end wall 1() a spool or annular flange 24. The flange 24 surrounds the diaphragm 17 and-the ring 22 and is of sufficient width to project into an annular depression 25 in the cheese arm surrounding the housing 18, the flange 24 thus extending across the gap between thecheese core and the cheese arm.

In practice, before placing the combined cheese core and supporting member upon the cheese arm, the operator strips off any yarn that may be upon the ring 24 or that may by some possibility be on the housing 18 or the spindle fr. The combined cheese core and supporting member is placed upon the cheese arm and latched, as hereinbefore'described. The latch holds the cheese in definite position by pulling thediaphragm 17 against the end wall 19 of the housing 18. The ring 22 does not rotate, and hence if the yarn being unwound from the bobbin should in some way yreach said ring, the lat-` ter will not act to unwind yarn from the IVhen the formation of the cheese has been completed, the operator pulls the cheese olf the cheese arm, the balls 20 yielding to allow the flange 23 to pass. The operator drops the cheese upon a spindle of a trident supported conveniently at hand. The cheeses are placed upon the trident in invariable position, with the latch side downward. It will be apparent that the fall of the first cheese to be placed upon the trident spindle is cushioned by the diaphragm 17. -When the next cheese is placed upon the spindle, the ring 22 of said cheese rests upon the diaphragm 16 of the first cheese, the fall of the second cheesev being cushioned by reason of the resiliency of the diaphragm 16 and 17 of the first cheese and the diaphragm 17`of the second cheese. By thus cushioning the fall of the cheeses, any tendcncy toward sliding of the yarn mass upon the cheese core is counteracted, and the combined cheese core and supporting member is protected from being knocked out of shape,` thus incidentally .reducing the liability to the production of so-called cobwebs in the operation of the Winder.

The diaphragms 16 and 17 constitute Ystructures .in the nature of circular flanges which are secured to the ends of the tubular support B1 are of sufficient diameter to overlie and underlie the ends of the yarn-carrier B2 and thus keep the latter out of contact with other units above and below it. If the blow of a falling unit were received by lthe yarn carrier B2 of a lower unit, the stresses would be transmitted to the tubular support B1 of such lower unit through the ball bearings, thus imposing excessive stresses on the bearings. 1With the construction herein shown, the weight of superincumbent cheeses is borne by the column of tubular supports.

lith previous styles of trident rollers, cheeses being unwound in the creel would occasionally run into Contact with adjacent cheeses, thus causing one thread to become slack. The slack thread sometimes caused stoppage of the warper'and even when it did not stop the warper it was objectionable because of the resulting lack of uniformity in thread tension. A11 accumulation of lint and yarn between the trident rollers also caused one cheese to drive another with the abovementioned results. Moreover, the cheeses would sometimes bound or rotate with a rolling action due to their being out of balance, thus causing` more tension on the thread.

It will be seen that vthrough the present invention ythe cheese arms ot the AWinderand the tridents ot the War-per Creel arev greatly simplified and cheapened, ball-bearing rollers on the cheese arms and the tridents be-v ing rendered unnecessary. The/pivot on the cheese arm becomes merely a stud or spindle, While the trident becomes simply a vbase With three plain spindles.

There beine' no shoulders or other projections within the sleeve l, the cheese core may be easily slipped on the spindle l claim as my invention:
