Definitions

  • the invention relates to knitting machines and more particularly is directed to multiple feed striping boxes such as used on circular knitting machines and periodically operated by mechanisms of such machines to move selected yarns into knitting and non-knitting positions.
  • Striping boxes such as disclosed in the said United States patents and patent application include a plurality of fingers which move selected yarns into and out of yarn feeding positions, the positions of the fingers being determined according to the operation of actuating drums. In this way color changes and other yarn changes in a fabric being knitted can be conveniently made according to a predetermined design.
  • FIG. 1 is a fragmentary top plan view showing the striping box of the invention on a circular knitting machine.
  • FIG. 2 is an elevational view of the striping box of FIG. 1 taken from the inside of the circular knitting machine.
  • FIG. 3 is a diagrammatic cross sectional view on the plane of the line 3-3 of FIG. 2.
  • FIG. 4 is an elevational view of the striping box of FIG. 1 taken from the outside of the circular knitting machine.
  • FIG. 5 is an enlarged exploded view showing portions of the striping box of FIG. 1.
  • FIG. 6 is a cross sectional view of the drum of the striping box.
  • FIG. 8 is a fragmentary sectional view showing a finger-actuating jack in one position between drum teeth.
  • FIG. 9 is a fragmentary sectional View showing the jack of FIG. 8 in a second position between the drum teeth.
  • FIG. 10 is a fragmentary sectional view showing the jack in the process of being pivoted about the jack retaining spring.
  • FIG. 11 is a fragmentary sectional view showing the jack in a third position between the drum teeth.
  • FIG. 12 is a fragmentary sectional view showing the jack in a fourth position between the drum teeth.
  • reference character 10 designates one of a plurality of striping boxes mounted on a stationary carrier ring 12.
  • the striping box 10 con tains four striping fingers or yarn carriers 14, '16, 18 and 20, such fingers being of conventional construction and containing apertures through which extend yarns 22, 24, 26 and 28, respectively, from cones on a yarn stand (not shown).
  • the striping fingers are pivotally mounted on rod 30 between check plates 32 and 34, and are each movable between an upper inoperative position and a lower operative position.
  • a selected finger such as finger 18 is in its lower operative position
  • the yarn 26 carried thereby is operatively engageable with a needle 36 whereby the yarn may be knitted into a fabric 35.
  • Movement of the striping fingers from their inoperative to their operative positions determine which striping yarns are incorporated into the fabric. Since the fingers may carry differently colored yarns or yarn of dilferent textures, various striped effects can be obtained by selectively operating the striping fingers of the striping boxes which may be positioned about a machine.
  • Each striping box contains an inner rotatable drum 38 mounted on a shaft 40 having one end affixed to an operating lever 42 as by set screw 44.
  • the drum 38 includes a midline annular groove 46 and like teeth 48 and 50, respectively, on opposite sides of the groove.
  • L-shaped jacks 52 are mounted in selected spaces between the teeth of drum 38 to actuate the striping fingers 14, 16, 18 and 20.
  • Such jacks are held in the drum by a spring 54 which registers with the groove 46 and engages the jacks in one of recesses 56, 57 or 58 formed in the jacks.
  • Recesses 56 and 58 are correspondingly located in identical legs 60 and 62, respectively, of the jacks, and the recess 57 is located between the legs as shown in FIGS.
  • Each finger has connected thereto a spring 64 normally urging the rear arm of the finger downwardly and the yarn carrying end of the finger upwardly.
  • the rear arm of a finger if not engaged by a jack 52, rests upon the surface of the drum teeth and the yarn carrying end of the finger is in its inoperative position.
  • the drum may, however, be moved to bring a jack into a position under the end of the rear arm and so cause elevation of the rear arm and a consequent depression of the forward part of the finger, whereby the finger is brought into its operative position (see finger 18 in FIGS. 1, 2 and 3).
  • the striping box is operated by an actuator 66 which is responsive to camming mechanism (not shown) of the type described for example in US. Pat. No. 2,543,121 mentioned hereinbefore.
  • Actuator 66 includes push rod 68 Which acts on one end of lever 42 at 70, the other end 74 of the lever being engageable with a plunger 76 slidably mounted in member 78 and biased against lever 42 by a spring 80.
  • Spring 80 acting through lever 42, urges the push rod 68 to a position wherein flange 82 on the lever engages surface 84 on member 78, and the spring is effective to return the lever to such stop engaging position after actuation of the lever by push rod 68.
  • Drum 38 is operatively connected to a uni-directional roller clutch comprising race 86 affixed in the drum, and rollers 88.
  • the shaft 40 directly engages the rollers 88 and also forms part of the clutch.
  • shaft 40 which is affixed to the lever 42 turns a fraction of a revolution and causes the clutch rollers 88 to bind in the race 86 such that the drum is immediately forced to turn with the shaft.
  • the drum 38 includes a number of detents 90 which project from one end surface of the drum, such detents being biased outwardly by springs 92 held in the drum by screws 94.
  • a plurality of recesses 96 equal in number to the number of pairs of aligned teeth in the drum 38 are provided in check plate 34 to receive the detents 98 and cause the drum when actuated by lever 42 acting through shaft 40 to move into a precise position which is defined by engagement of detents 90 in recesses 96 and wherein a pair of slots between adjacent teeth 48 and 50 and any jack therein is disposed directly under the extreme end of the rear part of a striping finger such that the finger is moved into its operative position.
  • the lever 42 is returned to its stop engaging position by spring 88 and the shaft turns with the lever but without moving the drum which maintains a fixed position wherein the detents 90 register in recesses 96.
  • striping box 10 has been described as having striping fingers 14, 16, 18 and 20 movable between an upper inoperative position and a lower operative position, it should be appreciated that the striping box construction described is not the only possible construction and that in another contruction the striping fingers might, for example, be spring biased toward a lower inoperative position and be subject to actuation by jacks of the striper drum into an upper operative position.
  • Jacks 52 are located in particular slots of the drum and in particular locations within the slots to provide for operation of the striping levers in a predetermined sequence.
  • the jacks 52 may be disposed with leg 62 in position A or in position B, and the jacks may also be disposed with leg 60 in position C or position D.
  • the jacks may be slid under the spring 54 between positions A and B or between positions C and D, and may be pivoted (FIG. 10) about the spring 54 between positions B and C.
  • the jack for any particular pair of slots of the drum may therefore readily be positioned to operate any one of the striping fingers 14, 16, 18 or 20, and it is unnecessary to remove a jack from the drum to change its position from any one of the four positions mentioned to any other of such positions.
  • more than four finger-actuating positions might be provided for in a somewhat wider drum than shown by utilizing jacks having longer legs than indicated and having more than one recess in each leg for the spring 54.
