  • the worm gear 54 is rigidly mounted for rotation upon the shaft 48 carrying the upper sliding block 46.
  • the worm gear 55 is' rigidly mounted for rotation upon a shaft 56 extending parallelto the-shaft '48.
  • this shaft 56 At the upper end of this shaft 56 there is mounted a pinion 57.
  • This pinion 57 meshes with the external gearing or teeth 58 of the hollow shaft 50 supporting the lower sliding block 47.
  • the re-- spective centers 59 and 60 of pairs of ring members 33, 34 and 35, 36 respectively, which form the circularshaped guide paths or tracks for the thread guide vanes or wings 7 and 8, are somewhat offset with respect to one another.
  • the center of the lower ring pair 35, 36 is disposed at the location indicated by reference numeral 60 and the center of the upper ring pair 33, 34, not visible in FIG. 3, is disposed at the location indicated by reference character 59.
  • the position of the thread guide vanes with regard to the centers 59 and 60 of their momentary revolving path of .travel is the same at each point of such revolving path of travel.
  • the thread guide vanes orwings always extend radially with respect to their associated centers 59 and 60 respectively.
  • the connection line 63 through the point of intersection of the tracks 61 and 62 is disposed perpendicular to a straight line 65 passing through both centers 59 and 60 and intersects line 65 at'the midpoint between centers 59 and 60.
  • the previously mentioned thread support 6 is secured to the lower plate member 28 and constructed as a circular or disc plate segment.
  • this circular plate 50 and which'support the sliding blocks 46, 47, is connected via a control rod arrangement with the pivot axis or shaft 12 of the rocker arm 11.

Consequently, the overlapping or intersection points 81, 82 of the vanes are located in their outermost or extreme position and the winding length is greatest.
  • the axis 78 is gradually displaced along the straight line 63 in the directionof the working region of the vanes 7 and 8 until reaching the terminal position depicted in FIG. 6, owing to the pivoting or rocking movement of. the rocker arm 11 through the agency of the control-means defined by the control rod arrangement. Consequently, the points of overlapping or intersection 8] and 82 of the vanes approach one another until they have reached their innermost position depicted in FIG. 6. In this position, the winding length is smallest. Owing to the gradual reduction in the winding length, there is produced the so-called pi'neapplelbobbin 82 as such'has been depicted in FIG. 6.
  • FIGS. 5 and 6 illustrate the vanes 7 and 8 in their one respective position. As will be observed by referring to these figures, owing to the occurring displacement of the axis 78 there is a change in sign in the bend between the vane and the sliding block in this-position.
