Definitions

  • FIG. 1 is an elevation of a bobbin constructed according to our invention.
  • Figure 2 is aplan view' of the structure shown m Figure 1.
  • FIG. 3 is a fragmentary vertical section through the structure appearing in Figure '1.
  • Figure 4 is a fragmentary plan view corresponding to Figure 2 but showing the parts in different relation.
  • the bobbin illustrated in the drawin comprises a spindle 1 the lower-part-of w 0b is of standard or ordinary construction adapted to be used on throwing machines of wellknown commercial types.
  • This spindle supports at substantial y right angles thereto a plate 2 having one or more tongues 3 bent downwardly from the central aperture therein and registering with flat ortions 4 on the spindle to key the plate to the spindle.
  • Fitted over the stem 5 of the spindle is a spool 6 secured in position onv the stem by a lock nut 7 which is threaded upon the u per end of the stem.
  • a suitable retaining device 8 may be employed to prevent accidental removal of the lock 'nutr a
  • the spool 6 is provided with a pair of suby parallel flanges 9 and 10 which are, provided with vertically ali ed apertures 11 and 12 to receive the ends of the vanes 13. These vanes form a-hub and are preferably in the form of wires bent to the form shown and,
  • This arrangement exemplifies means for pivotally mounting the vanes upon the spool, the vanes being held in position by the plate 2.
  • the vanes are adapted to expand outwardly from the axis of the bobbin and to be moved to and from the axis to vary the diameter of the hub which is formed by the vanes.
  • Each vane is provided with a lug 16 which may be conveniently formed by a loop in the wire forming the vane and each lug'extends into a slot 17 .in the plate 2.
  • These slots form cam means for guiding the vanes and for causing them to move toward or from the axis of the bobbin upon rotation of the spool.
  • These slots may be arranged atany suitable an le but we prefer to. make them substantia fly tangent to the circle formed by the apertures 11.
  • the plate 2 not only holds the vanes 13 in expanded position and holds them firmly against distortion, but also forms a support for the rayon cake and tends to keep the lower layer of filaments in their original order, thereby preventing breakage and waste.
  • hub of the bobbin is collapsed by turning the spool in the direction of the arrow in Figure 4, wherein the collapsed position is shown.
  • the hub of the bobbin is expanded, the maximum expansion being illustrated in Figures 1, 2 and 3.
  • the upper flange is knurled to form ready means for the turning operations referred to.
  • the lock nut 7 is tightened against the flange 10, this nut being knurled for this purpose.
  • the vanes are then held in proper position to form the desired diameter of the hub.
  • the above method forms a manner of im parting additional twist to rayon thread without the necessity of unwinding and winding with its attendant waste.
  • the twist imparted to the rayon in the spinning bucket is done while the rayon is wet, and therefore the amountof twist which can be given to the thread without materially decreasing production is limited.
  • a bobbin comprising a spindle, a. plate y an equally simple turn of keyed thereto and disposed substantially at right angles thereto, a spool mounted on said spindle, a plurality of vanes pivoted to said spool and provided with lugs received within cam slots in said-plate, a flange on said spool to permit manual rotation thereof, and a nut threaded on said spindle and adapted to contact with said flange to lock said spoolin method described extremely simple and eifi-
