  • Another object of the invention is to provide a very compact magnetic selector apparatus in which it is possible to stop the cam box of the machine in any position whereupon the operations can be continued by moving the cam box in the opposite direction.
  • every jack or sinker is held in contact with a slide surface of a selector magnet irrespective of the direction of relative movement between the control elements and the selector magnet.
  • a tensioning cam tensions a resilient means acting on each control element against the holding force of the selector magnet, but a cutout is provided in the proximity of which a selectively energizable selector pole can weaken the magnetic holding field so that the pretensioned resilient means turns the control element to another position.
  • the butt of the jack is located in a cam track when the jack is magnetical- 1y attracted to the magnetized slide surface of the magnetic selector means, and moves out of the cam track when displaced by pretensioned resilient means upon energization of the selector magnet pole.
  • One embodiment of the invention comprises a carrier member; a series of control elements, such as jacks, supported on the carrier member for movement between first and second positions for difierently controlling operations of a textile machine; a series of resilient means, preferably U-shaped springs having one leg connected with the control elements, respectively, for biasing the same toward the second position; and magnetic selector means including permanently magnetized first pole shoe means having a magnetized slide surface for holding the control elements in the first position whereby the resilient means are tensioned during relative movement between the selector means and the carrier member with the control element and the resilient means.

  • the cam box with the several cams thereof is assumed to move relative to the needles in the direction of the arrow A.
  • needles were upwardly guided and are returned by a cam 64 acting on butts 61 to the needle cam track 55.
  • FIG. 1 illustrates a construction of the magnetic selector head 65, which will be hereinafter explained in greater detail With reference to FIGS. 12 and 13. Not only the needle cam track 55, the jack cam track 13, and the selector head 65, but also to deflecting cams 53 and 54 form part of the cam box, and have the purpose of deflecting the jack butts out of the leading section 71 of jack cam track 13 so that the respective needles are not raised in this section.
  • FIGS. 2 and 3 illustrate an embodiment of the magnetic selector head 65 which is less complicated than the selector head illustrated in FIGS. 12 and 13, and also in FIG. 1.
  • a permanent magnet 1 is secured between a pair of soft iron pole shoes 2 and 3 which are temporarily magnetizable.
  • Pole shoe 2 carries a control magnet 4 consisting of laminated soft iron magnetizable sheets and having a rear part in contact with magnetizable pole shoe 2 over a large surface, and a control pole shoe 6 which is spaced a short distance from the magnetizable pole 2 and is parallel to the same.
  • a winding or coil surrounds control pole shoe 6 and magnetizes the same, when energized.
  • the control pole shoe 6 covers a cutout in the soft iron magnetizable pole shoe 2 and has an end face which forms together with the end faces of the magnetizable pole shoes 2 and 3, a continuous slide surface on which the respective armature surfaces of the jacks or other elements of a textile machine slide while being attracted by the permanent field of the permanent magnet 1, assuming that the winding 5 is not energized.
  • control pole shoe 6 displaced relative to the soft iron pole shoe 2 resides in that the control pole shoe 6, overlaying the cutout 9 in the soft iron pole shoe 2, is independent of the needle pitch or pitch of any other control elements so that its iron cross section can be freely selected as required by magnetic conditions so that unfavorable stray flux characteristics of the control pole shoe 6 can be avoided.
  • Control pole shoe 6 only acts on the jack which is directly located at the cutout 9.
  • the end face of a control pole, and adjacent end faces of auxiliary pole shoes form a continuous slide surface, with lateral slits between the control pole shoe and the holding pole shoe, and such slits are eliminated in the present invention.
  • the avoidance of the slits permits the use of the entire Width of the control region even for very narrow pitch between the needles and jacks so that the duration of the energizing pulse can be increased even for very narrow pitch so that a greater reliability of the function is achieved.
  • a further advantage is that the magnetic remanence and residual magnetism of the armature surface of the jacks caused by the engagement of the same by the pole shoe 2 is suppressed opposite the non-magnetic cutout 9 of pole shoe 2 in the controlled region, and does not exert a disturbing influence.
  • the soft iron holding pole shoes 2 and 3, the permanent magnet 1, the control pole 4, and a cover plate 8 are secured to each other by screws 7 which pass through corresponding slots 7 so that the relative positions of the parts connected by screws 7 can be easily adjusted.

Cutout 9 registers with another cutout 9 in pole shoe 3* under which a second control pole 4 with a pole shoe 6 and a winding 5 is arranged symmetrical to the control pole and pole shoe 4, 6.
  • the energizing pulse flows through both windings 5 and 5, the direction of winding of the two coils 5 and 5 being selected so that the permanent magnetic field is superimposed by an opposite magnetic field so that the magnetic attracting and holding field is attenuated when the coils are energized so that a jack, resiliently biased toward the holding field, drops on to assume a displaced released position.
