  • KNITTINCT MACHINE Filed Aug. 28, 1933 'T Sheets-Sheet 5 A l" j 22 e f' vATTy f Nov. 2, 1937.
  • This invention relates primarily to knitting machines and especially to knitting machines of the multi-feed type.
  • machines of this type it is essential, to knit uniform fabric, that the yarns of the several feeding stations be knitted uniformly into the fabric, i. e., that the stitches knitted at the several feeding stations be of the same length or otherwise what is commonly known as a washboard" effect is produced in the fabric.
  • Fig. 1 is a view in front elevation of a portionof a knitting machine having two feeding stations at each of which a yarn is fed to the needles which consequently knit two courses during each revolution of a rotary member such as a needle cylinder;
  • Fig. 1a is similar to Fig. 1 of a modication but not showing the needle cylinder and associated parts;
  • Eig. 2 is a View in side elevation, showing the automatically ⁇ controlled means for effecting the knitting of uniform fabric
  • FIG. 2a is a fragmentary detail view of the patterp drum for eecting automatic actuation of certain of the parts shown in Fig. 2;-
  • Fig. 3 is a View in side elevation of certainl parts showing controlling means for simultaneously changing the positions of stitchdrawing cams at the main and auxiliary feeding stations thereby to effect uniform variations in the stitches knitted at the two feeding stations;
  • Fig. 4 is a view similar to Fig. 1 but showing a modification
  • Fig. 5 is a view similar to Fig. 2 but of the l 4modification shown in Fig. 4;
  • Figs.v 6-10 inclusive are fragmentary views of the1 yarn controlling means disclosed in Figs. 4 and 5 but showing the parts relatively enlarged;
  • Eig. 11 is a fragmentary View of a still further exigon, being similar to Fig. 5;
  • Fig. 12 is a detail fragmentary view, in rear elevation, of a portion of the mechanism shown in'Fig. 11;
  • Fig. 13 is likewise a fragmentary view, in rear elevation, ⁇ showing how .swinging movements of one of the yarn controlling members are effected,
  • the needle cylinder I is shown as mounted for rotary and reciprocatory' movements in a socated substantially opposite one another with respect to the needle cylinder.
  • the needle cylinder is slotted in the usual manner and Within such slots are slidable needles.
  • a-sinker head 6 Surmounting the needle cylinder and connected thereto is a-sinker head 6 within which are mounted sinkers (not shown) adapted to cooperate with the needles in any desired manner for the formation of knitted stitches.
  • sinker cam cap l which is stationarily mounted and in which are cams for controlling the movements of the sinkers.
  • a latch ring 8 is carried by the machine frame and is pivotally mounted so as to be swung up away from the needles when necessary.
  • the yarn guide 9 being one of those located at or adjacent to the main feeding station, one of which guides feeds a thread or yarn II to the needles at the said main feeding station, the needles being actuated for knitting such thread by cams comprising the cam block l3.
  • the yarn lever I feeds the thread or yarn I2 to the needles at the auxiliary feeding station, the needles at such. station being controlled by cams comprising the cam block 4.
  • the yarns II and I2 are supplied from bobbins mounted upon a. bobbin stand (not shown) which is mounted upon a rod I3 and adjacent to the upper end thereof.
  • the yarns II, and I2 pass downwardly from the mentioned bobbins through suitable eyelets such as I4 and I5 and then between intermeshing rolls I6 and I'I.
  • the rolls I6 and I'I are mounted in substantially frictionless bearings consisting of pins or screws I8 and I9 which are mounted in the arms of a bracket 20, the eyelets I being carried by said bracket.
  • the bracket 20 is connected to and depends from an angle bracket 2
  • a supplemental bracket 23 tothe lower end of which is connectedan angle bracket 24 and a laterally projecting arm 25 pro-.- vided with eyelets 26 -through which yarns II and I2 pass.
  • the other arm of the A lever 28 is turned more or less at rightgangles and in the end .hereof is an eye'lf. 32 through which passes thelyarn I2.
  • the link 29 at its upper end passes through an arm 33 which is connected to and laterally projects from the yarn tension bracket y22.
  • a coil spring 34 Surrounding the link 29 between Vthe arm 33 and collar 30 is a coil spring 34 which normally urges the link 29 in a downward direction so that a lug 35 on a lever 36 to which'the link 29 is pivotally and adjustably connected as at 31, will be maintained in engagement with the surface of the drum 38 or cams 39 and 40 mounted thereon.
  • Bracket 4I Attached to rod I3 below the bracket 22 is a bracket 4I through which passes the rod or link 29.
  • a coil spring 42 is adjustably attached to the bracket 4I and exten-ds upwardly being connected to a yarn tension lever 43 which lever is one of a series of similar levers carried by knitting machines for the purpose of taking up the slack during the knitting of heels, toes and splitfoot fabric.
  • a yarn tension lever 43 which lever is one of a series of similar levers carried by knitting machines for the purpose of taking up the slack during the knitting of heels, toes and splitfoot fabric.

  • the threads or yarns I I and I2 are passed around the peripheries of the discs 48 and 49 being received in peripheral grooves thereof.
  • the threads II and I2 pass around the discs in. the same directions thereby causing the overlapping portions of the discs to rotate in opposite directions.
  • Discs 48, V49 are each provided with an equal number of equally spaced holes such as 52 and when the threads or yarns II and I2 are being knitted into the fabric by the needles knittingat the main and auxiliary' feeding stations, the frictional engagement between the said .yarns II and I2 and their respective discs 48, 49, causes the holes 52 in the two discs to move past one another at a rapid rate, the optical effect of which depends upon Whether the discs 48, 49 are rotating at the same speeds or at different speeds. If the two discs are rotating at the same speeds registering holes 52 in the two discs 48, 49 -give the appearance of black or dark spots which remain stationary.
  • the intermeshing gears or wheels I6 and I1 are provided. It is obvious that due to both yarns II and I2 passing between the ⁇ rolls or gears I6 and I1, that each yarn acts as a means for feeding the other yarn at the same rate that the first yarn is being fed. Thus even though the setting of the stitch drawing cams be not accurately adjusted, nevertheless thecompensating effect of the gears or rolls I6 and I1 will be such es to cause the fabric to have a uniform appearance.
  • a heel and toe yarn preferably, is substituted for the yarn or yarns used to knit the high-splice.
  • the heel or toe yarn may constitute a single yarn or plurality of yarns knitted as one-yarn.
  • Fig. 1a is shown a modification wherein the discs 48, 49 are dispensed with, the gears or wheels I6, I1 alone functioning to provide for the knitting of uniform stitches at the two feeding stations.

  • Both the rolls I6, II and bracket'member III act as yarn tension mem' bers in that they serve to equalize the tensions exerted on the yarns which are subject to constant changes due, in part, to uneven windings of the yarn cones, e. g.
  • the first yarn will tend to retard the rotary movements of the rolls I6, I1, or to swing the bracket I, in either case equalizing the yarn tensions. If the rolls I6, I'I be employed, a relatively tightr cone winding of one yarn will tend to retard the rotation of the said rolls which will subject the other yarn to a somewhat greater tension from the needles,
  • bracket member I II and associated parts be used, a relatively tight cone winding will cause the bracket III to rotate in a direction to decrease the tension exerted by the said bracket upon the said yarn which will, at the same time, cause an increased tension to be placed upon the other yarn; in other words, the tension bracket I
