BOBBIN HOLDER or YARNYW'INDIYNG srmnms I Application filed September 23, 1927f Serial No. 221,476.

Thifi lg invention relates to bobbin holders designed for use with spindles of yarn winding machines; and the object 1S to provide for the ready removal of the accumulated yarn on the bobbin holder without the. use of a yarn cutting instrument as is necessary with the present types of holders.

With this object in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is an elevation of a port on of a well known type of yarn windin'gmachine showing a spindle and its bolster casing, my improved bobbin holder, and a bobbin with its yarn load, the latter in dotted lines. Figure 2 is an axial section of the bobbin holder in detachable connection with the friction collar. Figure 3 is a lan view of the same, Figure 4 is an elevationof the friction collar; and Figure 5 is an elevation of the bobbin holder.

Referring to the drawings, in which like numerals indicate corresponding parts wherever occurring, 10 represents a portion of the stationary rail of a yarn winding machine for supporting the bolster 11 in' which the spindle 12 is rotatable. Above the rail and rigid with the spindle is the whirl 13,

adapted to be positively driven by a' band from a drum (not shown) in the usual man; ner. A collar 14 rotatable on the spindle is in frictional contact with the top of the whirl through a yielding pad 15 interposed between the collar and whirl. The collar is provided with a hub 16 to which the bobbin holder 17 is detachably securedand rotatable therewith. The'bobbin 18, loosely mounted on the spindle, is detachably connected by suitable means to the top of the bobbin holder, the rotative movement of which depends upon the degree of friction existing between the whirl, the yielding pad and the friction collar. I The bobbin holder 17 consists of a circularbody the upper end of which is enlarged forming a flange having a central tubular stud 19, which is adapted to fit into the base of the bobbin, and through which the spindle loosely passes. The holder and bobbin are detachably connected together by any suitable means, preferably by apin 20 fixed to the flange and adapted to coact with a socket in the base of the bobbin. .The lowerportion of the holder is counterbored to slid ably fit on the hub 16 of the friction collar and is detachably secured thereto by suitable means, preferably by a bayonetjoint comprising a pin 21 fixedly positioned to the periphery of the'hub 16 and coactir'g with a groove 22 cutin the surface of the counterbore 23 ofthe holder. The periphery of the lower ortion of the holder is tapered downwar from the. underside of its flanged'top thus facilitating the removal of yarn accumulated thereon from dofi'ed bobbins. i

In operation the spindle 12 is rotated independently of the bobbin by its whirl, and the friction collar 14 and the bobbin holder 17 thereon are rotated by friction between the yielding pad 15 and whirl upon which the friction collar rests, thereby maintaining the proper tension upon the yarn while being wound on the bobbin. After the bobbin has been filled and is ready for dofiin the traverse motion rod24 with yarn ui e 25 mounted thereon. is at the top 0 the bobbin, and the operator then lowers the guide below the bobbin so that the yarn-26 is wound on the tapering surface'of the hub of the bobbin holder, and the filled bobbin is removed and replaced by an empty one, so that 'a continuous strand of yarn is retained ready for repeating the operation upon the unfilled bobbin. The guide rod is then raised to guide the yarn to the lowest pulls the bunch of yarnfrom its position n the tapering body of the holder. By this construction less time is taken b the operator in removing the accumulate yarn than is now required in the use of a cutting instrument.

I claim 1 1. In a spindle, a blade, a whirl, a collar frictionally driven by said whirl, a bobbin holder supported on said collar and ,havin a bobbin engaging top portion and a conica yarn receiving body portion tapering continuousl downward to said collar, and means or detachably securing the collar and holder, said means being eifective to lock said holder to said collar and to prevent axial separation of said parts.

2. In a spindle, a blade, a whirl,'a collar frictionally driven by said whirl and havingan upwardly projecting hub, a bobbin holder slidable on said blade and resting on said collar and recessed to receive the hub of said collar, said holder having a bobbin engaging top portion and a conical yarn receiving body portion tapering continuousliy downward to said collar, and means for gtachably securing the hub of said collar and the recessedv portion of said holder together, said means being effective to lock said holder to said collar and to prevent axial separation of said parts.

In testimony whereof, have signed this specification.
