Definitions

  • spindles to be driven has usually run between two hundred and three hundred.
  • the spindles of such machines in some instances were individually driven by a cord which encircled a large pulley mounted on a drive shaft extending along the frame.
  • the drive shaft and the pulleys carried thereby were mounted in the central space between the two rows of spindles and each cord ran from its drive pulley around the whirl of the spindle and then back to the drive pulley, fitting tightly in a groove provided between flanges on the whirl.
  • the drive shaft and pulleys being located between the rows of spindles, access to the working parts of the drive was diflicult, and the arrangement required that the ends of the cord be spliced together after encircling the drive shaft with an appropriate length of cord.
  • the spliced joint in successively contacting the whirl, frequently subjected the spindle to repeated shocks which were objectionable.
  • the cords had to be frequently replaced due to rapid wear, and the drive required in other respects a considerable amount of servicing attention.
  • Belt drives then came into vogue in which one belt served a group of spindles, usually four in number.
  • these belt drives were also driven by a drive shaft located between the rows of spindles where access to the working parts was difficult, and required large driving drums or pulleys, which were mounted on the drive shaft.
  • these drums required an undesirably large amount of space.
  • the draft created by the large rotating drums has aggravated the fouling of the machine.
  • the large displacement required for belt drive mechanisms of the above type which consumed much space between and underneath the rows of spindles, access to many of the parts was very difficult and they therefore have been hard to clean and maintain.
  • the large displacement of the drive mechanism left little room for other necessary elements of the machine, and made it difiicult to cover the moving parts for safety purposes.
  • the endless belt drive mechanism of the present invention includes a drive shaft extending along the frame of the machine at the readily accessible side of the spindles to be served thereby i. e.
  • the drive shaft, drive pulleys and idler pulleys, and preferably the guide pulleys also, being all located at the readily accessible side of the spindles instead of between the rows of spindles or underneath the latter, all parts of the drive are readily accessible for inspection, cleaning or servicing, and a protective housing can readily be provided, and opened when access to the enclosed parts is desired.
  • the pulleys being coordinated as above set forth, the traverses of the belts, in passing to and from the whirls with their intermediate portions engaging respectively the drive and idler pulleys, follow paths which are located on the same side of the drive shaft.
  • the drive shaft is located exteriorly of the belts, thereby eliminating the drive shaft as an obstacle requiring the belts to be initially provided with open ends which would have to be spliced together after being placed in position encircling the drive shaft.
  • the invention enables continuous, jointless driving belts to be used, which have important operational advantages and are simple and facile to install and remove.
  • the sets of pulleys and driving belts as above referred to are so coordinated with the whirls of the respective spindles to be served, that each driving belt serves one of the spindles individually, although in one of the broader aspects of the invention as hereinafter referred to in more detail, the belts and pulleys may be so coordinated with the whirls that more than one spindle is driven by the same belt.
  • the frictional forces required to be set up between the belt, the whirl and the drive pulley may be substantially diminished, since whenever the spindle is braked to stop its rotation, the corresponding belt is not required to drive other spindles at full rotary speed while an individual spindle is stopped.
  • the moderate tension required for the corresponding individual belt will allow the latter to slip both with respect to its drive pulley and whirl, with the result that the whirl is only moderately strained and will not show wear even after a long running period.
  • the invention includes special features by way'of bracket mountings for the idler and guide pulleys, the brackets being detachably connected to the spindle or frame structure so that machines equipped with other forms of spindle driving mechanism, may be readily reconstructed to utilize driving mechanisms as herein contemplated, with a minimum of internal alternations to the spindle and frame structure ofthe machine.
