Definitions

  • This invention relates to improvements in mechanisms for operating weft inserting needle carriers of the type shown in Turner Patents Nos. 2,625,959 and 2,902,057, more particularly like that shown in Patent No. 2,902,057 but where there are two weft inserting needle carriers for weaving two separate fabrics side by side.
  • each carrier a uniformly rotating actuator and a pivoting link which rocks about a fixed pivot and is pivotally connected to said carrier.
  • the actuator and link cooperating to operate the carrier to move the needle through the warp shed in a smooth continuous tear drop path having an accelerated motion while it is in the warp shed and retarded motion while it is out of the shed to provide sufficient time for the harness mechanism to change warp sheds between successive insertions of the needle.
  • FIGURE 1 is a plan view illustrating the invention as applied to a needle loom
  • FIGURE 2 is a vertical section on line 2-2, FIGURE 1 and looking in the direction of the arrow,
  • FIGURE 3 is a diagrammatic view showing the motions of the various components of the weft inserting mechanism.
  • FIGURE 1 there is shown a needle loom with the usual harness frame 4 reciprocable vertically in guides 5 and 6 by mechanism, not shown, but similar to that employed in Patent No. 2,625,959.
  • the harness frames actuate the warps 8 to form two separate sheds through which the wefts 10 are inserted to form fabrics 12.
  • the loom operates with the usual beat up means 14 and selvage forming mechanism 16.
  • right and left weft inserting means 20 and 22 which include right and left hand weft needle members 24 and 26 each with a weft inserting eye 28 at its forward end.
  • right and left actuators 30 and 32 which are fixed to vertical shafts 33 and 34 respectively.
  • Shafts 33 and 34 are supported in table 18 and are continuously driven in synchronism through equal bevel gears 36 which mesh with bevel gears 38 on a drive shaft 40.
  • Drive shaft 40 is driven by other conventional driving means, not shown, in timed relation with other operating 3,291,159 Patented Dec. 13, 1966 ice mechanisms of the loom.
  • actuators 30 and 32 rotate constantly at equal rates although actuator 30 rotates counter-clockwise and actuator 32 rotates clockwise as viewed in FIGURE 1.
  • Needle member 24 is pivotally attached to actuator 30 at a point spaced from its needle 28 through a pivot pin 42 whose axis is also vertical but spaced from shaft 33 and consequently for every rotation of the shaft 33, pin 42 turns in a circle around the axis of shaft 33 said circle being designated by the reference character 44, FIGURE 3.
  • Needle member 26 is likewise pivotally connected at a point spaced from its needle 28 to actuator 32 by a pivot pin 46 which rotates around the axis of shaft 34 in a circular path designated by the reference character 48, FIGURE 3.
  • Needle members 24 and 26 are drivingly interconnected by cross links 50 and 52.
  • Cross link 50 is pivotally connected at one end to needle member 24 through previously mentioned pivot 42 and at its other end to a pivot 56 on a portion of needle member 26 which is further forward of needle eye 28 than is pivot 46.
  • the other cross link 52 is pivotally connected at one end to needle member 24 at pivot 46 and at its other end to member 24 through a pivot pin 54 located on a portion of member 24 which is forward of pivot 42.
  • both needle eyes 28 move toward each other from the extreme outer position shown in full lines to the dotted line portion in FIGURE 3 and then away from each other toward the full line positions.
  • the distances between the inner and outer positions of the needle eyes 28 are twice as much as would be obtained if the actuators alone were used to drive their respective needle members with the forward portion pivoted, as for instance in Turner Patent No. 2,902,057, without any increase in the front to back motion of the needle eye.
  • weft inserting means comprising:
  • weft inserting means comprising:
  • each needle member having a first and second pivot point and a weft eye at the rear end thereof
  • weft inserting means comprising:
