Definitions

  • a bearded needle p knitting machine comprises needle bar, a sinker bar and a guide bar, drives for the E (gl bars the guide bar drive including a push rod 58] Fieid 66/86 R mounted on the drive shaft for the needle bar drive, a control arm for the sinker bar drive also mounted on [56] References Cited this drive shaft, and a lever connection between the UNITED STATES PATENTS control arm and the sinker bar drive.
  • the present invention relates to improvements in a bearded needle warp knitting machine useful particularly in knitting fabrics for mens and womens garments.
  • Raschel knitting machines have been used for this purpose, and their operating speed has been considerably increased by imparting opposite motions to the knitting needles and yarn guides.
  • Such motions are possible only in Raschel machines working with latch needles and a knocking-over bar which does not move relatively to the knitting needles in the rocking direction. It has not been possible to proceed in a like manner in bearded needle machines, particularly those with several laying-in bars, to profit from the high operating speeds of such machines.
  • It is the primary object of this invention to overcome this disadvantage and to make use of bearded needle warp knitting machines comprising a needle bar carrying bearded knitting needles, a sinker bar carrying sinkers, and a guide bar carrying yarn guides.
  • Such machines have a drive for the needle bar including a drive shaft, a drive for the guide bar including a push rod, and a drive for the sinker bar.
  • the push rod for the guide bar drive as well as a control arm for the sinker bar drive are mounted on the drive shaft for the needle bar drive, and a lever connection is provided between the control arm and the sinker bar drive.
  • a first bushing carrying the push rod for the guide bar drive is eccentrically mounted on the drive shaft for the needle bar drive
  • a second bushing having an arm carrying the needle bar is mounted eccentrically on this drive shaft diametrically opposed to the first bushing
  • the main drive for the machine is connected to the bushings by rocking arms.
  • control arm is fixedly mounted on the drive shaft for the needle bar drive
  • lever connection includes a bell crank lever and a connecting rod between the control arm and the bell crank lever
  • sinker bar drive includes a drive shaft and a rocking arm mounted on the drive shaft for the sinker bar drive and driving the sinker bar
  • machine further comprises a main drive for the machine, the bell crank lever being connected to the main drive and to the rocking arm of the sinker bar drive.
  • the machine may be adapted to the use of a varying number of laying-in bars by an adjustable arrangement wherein a push rod connects the main drive of the machine with the needle bar drive, a connecting fulcrum is provided between the push rod and a rocking arm of the needle bar drive, and means is provided for adjusting the fulcrum in the longitudinal direction of the rocking arm for changing the effective length thereof.
  • FIG. 1 is a transverse section showing the main drive of a bearded needle warp knitting machine according to this invention, together with the needle and guide bars with their drives;
  • FIG. 2 is a similar transverse section showing the main drive and the sinker bar with its drive;
  • FIG. 3 shows displacement diagrams of the swinging motions of the laying-in bars, the needle bar and the sinker bar
  • FIG. 4 shows a detail of the fulcrum connection between the main drive and the needle bar drive rocking arm.
  • the needle bar 1 is shown fixed to car-' rier arm 2 which is reciprocated by push rod 3 connected to the eccentric main drive 9, 10 of the machine in a conventional manner (see, for instance, page 16 of Warp Knitting Technology" by D. F. Paling, Columbine Press, Manchester & London, England, 1965
  • the bushing 4 is mounted eccentrically on the drive shaft 5 for the needle bar and the carrier arm 2 is affixed to the bushing.
  • a rocking arm 6 is also mounted on the drive shaft 5 and a fulcrum 28 connects a push rod 7 to the rocking arm, the fulcrum being adjustable in an elongated slot 28a in the longitudinal direction of the rocking arm for changing the effective length thereof.
  • the push rod 7 is connected to the crank drive 9 by means of connecting rod transmission 8, the crank drive being mounted on main shaft 10 of the machine.
  • Another bushing 4 is mounted eccentrically on drive shaft 5 diametrically opposed to bushing 4, the bushing 4' carrying the push rod 11 for reciprocation of the guide bar 12.
  • the arranged of the preferred illustrated embodiment is such that, when the needle bar swings in the direction of arrow 13, the laying-in or guide bar 12 swings in the opposite direction, i.e. in the direction of arrow 14, due to the diametrically opposite arrangement of the eccentric bushings 4 and 4'.
  • FIG. 2 illustrates the sinker bar drive.
  • a control arm 15 is fixedly mounted on drive shaft 5 for the needle bar drive, and a lever connection is provided between the control arm 15 and the sinker bar drive.
  • the lever connection illustrated herein includes a connecting rod 16 and a bell crank lever 17, one arm of the bell crank lever being linked to the connecting rod 16.
  • the sinker bar drive comprises a shaft 20 and a control arm 19, the pivot 18 of the bell crank lever being linked to the control arm 19.
  • the other arm 21 of the bell crank lever is linked to push rod 22 connected to crank drive 24 by means of connecting rod transmission 23,
  • crank drive being mounted on main machine shaft
  • Connecting rod 27 links control arm 19 to carrier arm 25 of the sinker bar 26 so that the control arm drives the sinker bar
  • the illustrated arrangement syn chronizing the opposite swinging motions of the needle justably connected so that the connecting fulcrum 28 may be moved
  • the machine may be readily adapted, for instance, from four guide bars (fulcrum in the illustrated end position in slot 28a) to three guide bars (fulcrum in the other end position in the slot).
  • a bearded needle warp knitting machine comprisl. a needle bar carrying bearded knitting needles,
  • a drive for swinging the needle bar including a carrier arm and a shaft supporting the carrier arm,
  • a drive for swinging the guide bar including a push rod mounted on the needle bar drive shaft for swinging the guide bar in a direction opposite to the direction of swinging of the needle bar,
  • the bearded needle warp knitting machine of claim 1 further comprising a first bushing eccentrically mounted on the shaft for the needle bar drive, the first bushing carrying thepush rod for the guide bar drive, a second bushing eccentrically mounted on the shaft for the needle bar drive diametrically opposed to the first bushing, the carrier arm carrying the needle bar mounted on the second bushing, a main drive for the machine, and a rocking arm connecting the bushings with the main drive.
  • control arm is fixedly mounted on the shaft
  • lever connection includes a bell crank lever and a connecting rod between the control arm and the bell crank lever
  • sinker bar drive includes a shaft and a rocking arm mounted on the shaft for the sinker bar drive and driving the sinker bar, and further comprising a main drive for the machine, the bell crank lever being connected to the main drive and to the rocking arm of the sinker bar drive.
  • the bearded needle warp knitting machine of claim 1 further comprising a main drive for the machine, a push rod connecting the main drive with the needle bar drive, the needle bar drive including a rock ing arm, a connecting fulcrum between the push rod and the rocking arm, and means for adjusting the fulcrum in the longitudinal direction of the rocking arm for changing the effective length thereof.
