Definitions

  • My Vinvention relates'to improvements in doti-ing apparatus for spinning frames ot thelrin'd designed to travel along the sides ofthe spinningirame to remove the full bobbins from thespinning spindles and' ref place themfby'empty' bobbins and the object of the invent-ion. is to devise means for removing a predetermined number of the full bobbins at a time and replace them by the san'ievnumber of empty bobbins.
  • Another object is to devise means for shitting the full bobbin chuck arms out of alignment with 'the vspinning spindles in order to permit the emptyT bobbin chuck arin's to come-down in alignment with the spindles, thus enabling the device to remain stationary during the complete operation 0n a section of bobbins.
  • Hy invention consists of a dotling apparatus constructed and arranged, all as hereiuat'ter more particularly described and iilustratedin the accompanying drawings iu which:
