Definitions

  • the present invention relates to: an extensible swift for the winding ofhanks of silk, cotton or other yarns of different diameters of the type in which by rotation of central cage with respect to the shaft the arms supporting the hanks are moved radially.
  • each supporting member being formed with two connecting arms inclined towards each other alternately to right and left of their pivots so that in the contracted position they will not foul adjacent arms.
  • the invention also includes a further arrangement in which each of the aforesaid arms are connected together in pairs at their ends by one or more cross members which form two open resilient straps in which the arms are held and which are therefore readily interchangeable.
  • Fig. 1 is an elevation showing the arms in the contracted position.
  • Fig. 2 is a section on line 2-2, Fig. 1.
  • Fig. 3 is an elevation partly in section on line 33, Fig. 1, with the cranks rotated to extend the arms to their maximum extent.
  • Fig. 4 shows the inner discs with a pair of connecting arms rotated to give the arms their minimum diameter.
  • Fig. 5 is a transverse section on line 55, Fig. 1, with the arms in an intermediate position.
  • the apparatus comprises a cylindrical cage a freely mounted on a shaft 0 and having a surrounding flanged disc I) affixed to the shaft 0.
  • a sleeve 6 supporting two flanges or discs d.
  • the sleeve 6 is keyed to the shaft 0 so that the members I), c, e and d are relatively stationary.
  • the discs d carry pins 1, at equal distances from their centres, on which are pivoted preferably on the inside of the discs, connecting arms 9 (Figs. 3 and 4) v
  • the number of these pairs of arms may be 4, 5, 6, '7, 8, 9, 10, 11, 12 or more.
  • a swift is shown having 8 pairs of arms.
  • connecting arms r are not parallel but on the other hand are inclined one to the right and the other to the left towardseach other.
  • This inclined position with respect to the disc 11 is the characteristic arrangement of the present invention and is necessary in order that the pairs of connecting arms shall not foul each other when they are withdrawn to their limit into the cage a.
  • each pair of arms is connected together at its outer end by a cross member h and at its other ends to the pivots f on the discs (1 (Figs. 3 and 4) If desired the connecting arms may be mounted outside the discs in which case their inclination will be reversed.
  • the connecting arms pass through slots or openings in the cage (1.
  • each cross member h for the pairs of connecting arms is formed of two members of spring steel curved at their outer ends to form two straps or resilient clamps i (Fig. 2).
  • Each yarn supporting arm :1 is formed with two portions (Figs. 1 and 3) which are engaged between the two ends of the clamps i which allows for readily detaching and changing the arms.
  • a brake drum n is shown affixed to the flanged disc b but it may be keyed to the shaft 0..
  • the shaft c is hollow and is provided with two interchangeable pivots 0 which may be screwed or affixed by lock nuts.
  • An expansible swift for hanks of textile yarn of the type referred to comprising a shaft, a slotted cage loosely mounted on the shaft, discs keyed to the shaft one at eachend of the cage, a plurality of converging arms pivoted in pairs on the discs with each pair projecting through a slot in the cage, a pair of resilient transverse members connecting the two arms of each pair together and yarn carrying arms secured to the transverse members.
  • An expansible swift 8501' hanks of textile yarn of the type referred to comprising a shaft, a slotted cage loosely mounted on the shaft, discs keyed to the shaft one at each end of the cage, a plurality of converging arms pivoted in pairs on the discs with each pair projecting through a slot in the cage, a pair of resilient transverse members connecting the two arms of each pair together, clips on the ends of the transverse members, and yarn carrying arms mounted in the clips on the transverse members.
