Definitions

  • HOUR BAR ADJUSTMENT MEANS EUR 'lflUlF'HliNG MAClilllNlES
  • the invention concerns tufting machines and has more particular reference to the mounting of looper or hook bars relative to a shaft therefor.
  • looper or hook bar is secured relative to the looper or hook shaft by means of spaced clamping brackets which embrace the said shaft, the bar being carried by the said brackets in any convenient way.
  • the brackets are mounted on the shaft at a requisite angular disposition thereon and are secured in such position by an appropriate tightening of screws which hold the bracket parts together. Any necessary adjustment of the angular position of the brackets can be effected by slackening off the screws, or alternatively the adjustment can be effected by varying the angularity of the shaft as a whole.
  • the primary object of the present invention is to provide a simple means whereby the angular position of the looper or hook bar (or looper or hook bar sections if the bar is provided in this form) relative to the looper or hook shaft may be adjusted both accurately and effectively.
  • FlG. Il is a front elevation of a part of a hook bar shaft assembly embodying the invention.
  • a hook shaft assembly includes a hook shaft lil, two mounting brackets l2 arranged in spaced disposition upon the shaft there being further such brackets at intervals along the shaft), and a hook bar section 113 secured to such brackets.
  • Each bracket i2 comprises a generally rectangular body part 12a having a substantially semi-cylindrical recess 12a' therein to receive the shaft if and a capping plate ]lZb likewise having a part cylindrical recess 12b', for engagement with the shaft, the body part and capping plate being secured together by screws 12e.
  • brackets ln setting up the assembly the brackets are loosely mounted on the shaft ll so as to be freely movable angularly thereof and a requisite angular position of the brackets B2 (and thus of the hook bar or hook bar sections 13) is achieved bv suitablv adjusting the position of the lock nuts Md.
  • the brackets l2 are then firmly ⁇ secured to the shaft l1 in their assumed positions and the assembly is adjusted for operation.
  • a hook shaft assembly for a tufting machine comprising a hook shaft, a hook bar mounted longitudinally thereof and mounting brackets supporting the said bar at a requisite angular position relative to the shaft, the improvement comprising an adjustment means between the brackets and shaft adapted to effect an angular adjustment of the brackets relative to the shaft.
  • adjustment means includes an adjustment screw operatively connected to one of the parts to be joined and a reaction lug secured to the other of such parts and with which such adjustment screw coacts.
