Definitions

  • ABSTRACT A dobby controlled weft yarn selecting system for use in connection with shuttleless looms where a plurality of yarns are presented for insertion into the warp shed, the improved system includes means whereby the various cables that connect the dobby to the yarn selecting mechanism are connected by means that permits initial movement of the dobby connecting cables before any commensurate movement of the yarn selecting cables is effected.
  • a further object of this invention is to provide a weft yarn selecting mechanism in which a textile dobby is used to select a given yarn from a plurality of sources for insertion into the warp shed on a shuttleless loom.
  • Yet another of this invention is to provide a dobby control weft yarn selecting system in which the yarn is moved into position by a plurality of weft insertion elements and in which no dobby motion is imported to the selecting elements.
  • FIG. is a side elevation, particularly fragmentary of a weft yarn selecting system according to this invention.
  • Each of the yarn elements 10 is continuously biased toward the yarn presenting position by the coil springs 12 that are secured at their lower ends to extensions 13 on housing 1 l and upper posts 14 that are attached to or form a part of the upper end of each of the yarn elements 10-.
  • the housing 11 is itself appropriately mounted on the frame 15 that is secured to the main frame of the loom.
  • the yarn elements 10 are normally maintained in their uppermost, retracted, inactive position by the act of actuating cables 20 that are also attached to the upper ends of each of the yarn elements 10.
  • actuating cables may conveniently take the form of Bowden wires, although the particular type of cable used is 7 not important to this invention.
  • the construction shown in FIG. 1 illustrates that the upper, free ends of cable 20 are fastened to a bracket 21 that is itself secured by a suitable fastener 22 to the frame 15. From this mounting the inner cores of the actuating cables are joined to connecters 23.
  • Each of these connecters is in turn slidably attached to a lever member or platelike element 25 that is mounted for pivoting about axis 26 so that it can move between the lower active position 27 and the upper inactive position 28, as shown in the drawing.
  • This plate-like means 25 serves as a means which operably connects actuating cables 30 with the upper, free ends of actuating cables 20. At one end the cables 30 are connected to the dobby jacks 31 and at the other or free end are slidably joined to the platelike members 25 as indicated by the number 32.
  • springs 35 which at their lower ends are connected to a bracket 36' that is in turn secured to frame 15.
  • the upper ends of springs 35 are connected to plate-like members 25 so that they continuously bias these members toward a position where all of the control elements 10 are in the inactive position until the dobby jacks have moved element 25 to the lower position 27, thereby permitting a spring 12 to pull one of the elements 10 to its lower, active position.
  • Two important features of the means for operably connecting the free ends of the actuating cables to the free ends of the control cables is that those ends of the respective cables that are not connected to the dobby jacks and to the selecting elements that are slidably connected to member 25.
  • the operating connection 32 is made possible by virtue of a generally horizontally extending slot 39. This slot makes it possible for a control cable 30 to commence initial movement without effecting similar movement of an actuating cable 20, because element 25 will not begin to rotate until the fastener 32 travels the entire length of slot 37.
  • a dobby controlled weft yarn selecting system for use with a shuttleless loom to present yarn from a stationary source to a preselected location for insertion into a warp shed, said system comprising:
  • control cables connected at one end to the dobby
  • a lever member pivotable between a lower active position and an upper inactive position having means for slidably and operatively connecting the free ends of said actuating cables to the free ends of said control cables whereby a selected yarn engaging element is delayed in its movement into and from the active position.
