  • the normal position of a control spring 7 is shown in FIG. 1, but during rotation of the dial 1 relative to cams K1 and K2, each control spring 7 is raised to the higher tensioned position shown in broken lines in FIG. 1, or may be bent down to the lower tensioned position shown in broken lines in FIG. 1.
  • a control spring 7 in the higher position will engage the lower face of projection 6b and hold the respective coupling member 6 in the position illustrated in FIG. 5 in which the lower edge of coupling projection is located above, and does not engage the slots 5b and 5c of the respective dial needle 101.
  • projection 60 will cooperate with coupling projection 5a during inward movement so that the dial needle can be retracted in this position of the coupling member but not advanced.
  • each coupling member can remain in this position even if the respective control spring is in the normal straight position illustrated in solid lines in FIG. 1.
  • a control spring 7 is bent to the lower position shown in broken lines in FIG. 1, then a force will be exerted on coupling projection 60 to urge the same into an aligned slot 5b or 5c in which event coupling member 6 will be coupled with the respective dial needle 101 for radial movement under the control of the pair of cooperating cams K3 which are designed to cause a movement of the dial needles in radial direction for a distance corresponding to the desired displacement of the dial needles between a retracted inoperative position and an advanced operative position.
  • coupling member 6 When the coupling member 6 is in the position shown in FIG. 1 with coupling projection 60 located outside of the coupling slots 5b and 5c, but in engagement with the front edge of projection 50, coupling member 6 is coupled to dial needle 101 only for movement in inward radial direction.
  • the endless cam K4 cooperates with the projections 6b of all coupling members 6, and dwells of cam K4 will cause coupling member 6 to tilt downward about edge 6f so that coupling projection 60 will pass into an aligned coupling slot in the corresponding dial needle 101, in the same manner as if coupling member 6 were tilted by the corresponding control spring 7.
  • cams K3 will act as control means for moving coupling members 6 and dial needles 101 in radial direction between inner and outer positions
  • cams K1, K2 and K4 as well as control springs 7 will act as control means for moving coupling members 6 between the inoperative position illustrated in FIG. 1 and a coupling position in which coupling projection c engages one of the coupling slots 5b or 50.
  • each control spring 7 will be guided along the upper cam track of cam K11 when dial 1 rotates in the direction of the arrow X.
  • each control spring 7 will be in a tensioned higher position, and will be in contact with, or very closely spaced from the end face of the pole 8a of an electromagnetic selector 8. If electromagnetic selector 8 is energized at this moment, it will hold the respective control spring in the higher tensioned position, only little magnetic force being required since the bending of control spring 7 from the normal position to the higher tensioned position is not affected by the force of the electromagnetic selector 8,. but by cam K1 and by the drive torque of the rotating dial 1.
  • control spring 7 in the upper tensioned position will be held by pole 8b until the respective portion 7b, traveling with the dial, arrives at the upper cam track KZa. Return of control spring 7 to its normal position is prevented by cam K2.
  • Pole 8b may be permanently magnetic while the narrower pole 8a is selectively magnetized by a corresponding selectively energized winding of electromagnetic selector 8 to attract only certain control springs 7 while exerting no magnetic force on other non-selected control springs 7 whose associated dial needles are not to be advanced in accordance with the pattern. It will be understood that the winding of electromagnetic selector 8 is energized or not energized, respectively, under control of pattern means which are set to a selected program of knitting operations.

  • FIG. 70 illustrates in a horizontal view cams K3 which effect the radial movement of coupling members 6 for the purpose of shifting those dial needles 101 which are coupled to the respective coupling members 6.
  • FIGS. 7a to 7d Corresponding points of FIGS. 7a to 7d are related by ordinates extending in radial planes passing through the axis of rotation of dial 1. Circumferential sections are indicated by capital letters appearing below FIG. 7d.
  • a knitting station, where the dial needles have to be arranged in operative and inoperative positions, respectively in a selected order corresponding to the desired pattern to be knitted on the knitting machine, is assumed to be located before the beginning of the circumferential section A, and another knitting station is assumed to be located at the end of the circumferential section 0.
  • the circumferential section G may be considered as a selectinfi station since at this point electromagnetic selector 8 is energized or de-energized in accordance with a pattern to cause selection or non-selection of control springs 7 which determine a corresponding selection of dial needles 101.
  • dial needles 101 are arranged in inoperative or operative positions in accordance with the pattern required for the preceding knitting operation in the preceding circumferential section of the knitting machine.
  • Dial needles 101 have passed through the feeding station, and move along the circumferential section A in the direction of the arrow X due to the rotation of dial 1 with the needle cylinder.
  • FIG. 7c! shows two parallel lines in the section A which means that some dial needles are in the outer advanced operative position, and other dial needles are in the inner retracted inoperative position. The old order of dial needles is still maintained in section B.
  • Control springs 7 are raised in section B as shown in FIG. 7a.
  • Cam K4 has a thinner portion in section B so that spring 7 can raise coupling member 6 by engaging projection 6b from below. Consequently coupling projec tions 60 are pulled out of slots 5b and 50 while the respective coupling member 6 tilts in counter-clockwise direction about its bottom edge 6
  • cams K3 are effective to withdraw coupling members 6 to an inner position. Since coupling projections 6 are no longer located in slots 50 of inoperative retracted dial needles, the inward movement of the respective coupling members 6 has no influence on the associated dial needles. However, previously operative advanced dial needles 101 will be retracted, since coupling projection 6c engages the outer edge of coupling projection 5a of the respective dial needle.
  • FIG. 1 shows dial needles 101 and coupling members 6 in the retracted position, but in section D, in which no change of position takes place, control springs 7 are in the upper tensioned position shown in broken lines in FIG. 1.
  • cams K3 advance coupling member 6 so that coupling projection 60 is located between coupling slots 5b and 50, as shown in FIG. 5.
  • the positions of control springs 7 remain the same, and coupling members 6 are not tilted.
  • springs 7 are permitted to move downward for a small distance, and cam K4 urges coupling member 6 to move down a corresponding distance so that the lower edge of coupling projection 60 actually abuts the upper edge of dial needle 101, as shown in FIG. 5.
  • coupling members 6 are not displaced by cams K3 and K4, but remain with the retracted dial needles 101 in the position of FIG. 5.
  • Control springs 7 are successively guided into the proximity of selector pole 8a.
  • the winding of electromagnetic selector 8 is alternately energized and de-energized in accordance with a program tape in a sequence corresponding to the desired new pattern in which the dial needles have to be arranged during the following knitting operation, as will be understood by those skilled in the art.
  • selector pole 8a. is not energized when a control spring 7 passes beyond the end of cam K1, the respective control spring 7 is released and tends to resiliently assume its normal straight position, or slightly beyond the same. Control springs '7 in this position pass into the region of the lower cam track K212 and will. remain in the normal position while moving through sections H, J and K.
  • control springs 7 on cam track K241 are slightly raised.
  • Cam K4 is recessed to permit an upward movement of the corresponding coupling members 6.
