Definitions

  • knitting machines which comprise a series of sliding needles mounted on a carrier and adapted to. be moved between the needles of a needle bar which is demountable'from the said carrier, for the purpose of pulling out a correspondingly inserted working thread to 'zig-Z'ag 'nooses, the slidin'gneedles being advanced and then returned through elements provided with cam faces.
  • the zig-zag nooses subsequentlyare tied by throwing the previously formed row of loops hanging from the needle bar fromthe front to the rear, thereby producing a' new row of loops.
  • cam faces as slides, one suchQslide having four .cam faces being providedfor example, or two slides each having two cam faces.
  • looped fabrics which looks different on its sides, that is, plain common hosiery, in'such manner that the work always'hangs rearward of the needle bar, intermediate of the'latter and the carrier, in a free space provided for such purpose, whereby for the purpose of continuing the knitting operation, the 'Zig-zaglo'op'shave to be thrown cfi'the needle heads 'of'the needle bar or, when using. latch or "tumblindeedlesythe saidloops have to be drawn through the loops of the loop row formed last.
  • a series of movable needles, preferably sliding needles, on a carrier are adapted to be moved between the set of needles of the needle bar which is detachable from the carrier, and two actuating members, for example, slides, are provided by means of which the movable needles can at times be moved temporarily between the needles of a movable needle bar disposed on the carrier member, so as to enable an inserted thread to be pulled out into a zig-zag loop, the knitted workpiece being thrown over the head of the bar needles at each workingstep with the last-formed row of loops extending from the front to the back so as to bind a new row of loops.
  • the support member of the aforesaid knitting arrangement is provided with a seat for temporarily receiving a second needlebar, said seat assuming an acuteangle position with respect to the first needle bar, in order to be able to transfer a knitted workpiece hanging on the needles of the firstnamed needle bar to the set of needles of the second bar for the purpose of continuing the knitting operation with the second needle bar instead of with the first needle bar.
  • Fig. 1 shows a plan'view of the left and the right side of the carrier, whereby for clarifying purposes the cover of the operatin gear has been removed, one needle bar being inserted on the carrier proper, and the other needle bar in two supports.
  • Fig. 2 shows a side view of Fig. 1, the side wall. being broken away for the purpose of illustrating the operating gear
  • a Figs. 3 and 4 show,.inla larger scaleand in two views taken at right angles to each other, the interengaged needle heads of the two needle bars for the purpose of transferring the ware from one of said bars onto the other.
  • Fig. 5 is a side view similar to Fig. 2 of part of the structure of Fig. 1, and partially in section, illustrating a removable mounting of support brackets;
  • Fig. 6 is a broken away View of part of Fig. 5 illustrating a detail of the removable mounting.
  • numeral I designates an oblong casing serving as carrier, with the sliding needles 2
  • numeral 3 designates the left-hand slide and 4 the right-hand slide with the cam faces 3' and 4 respectively.
  • the latter serve for returning the sliding needles 2 for the purpose of pulling out the zig-zag nooses.
  • the slides 3 and 4 further are provided with a cam face 3" and I" respectively, for advancing the needles 2 for the purpose of forming the trick or needle canal into which the free workin thread is inserted.
  • the supple tension element 5 formed by a cable for example and which at its ends is resiliently secured to the carrier I by means of springs S and T, aids in advancing the needles 2 and locates the latter in the frontmost position. For such latter purpose, the tension element 5 is engaged on a bend 2' of the needles 2.
  • the slides 3 and 4 may he slid on the rail 8 in either direction.
  • the needle bar 9 is inserted in its two brackets II and II provided on the carrier I. As shown in Fig. 2, the bar 9 is in an inclined position on the carrier I, and the work I3 hangs in its needles I2 rearwardly over the carrier I. position, the work I3 is thrown forwardly over the second needle bar I4 so that the loop row formed last on the work I3 is transferred from the needles I2 of bar 9 onto the needles I5 of bar I4.
  • the bar I4 has been inserted into the brackets I5 and il secured to the carrier I.
  • the heads I2 of the needles I2 of bar 5 are provided with a groove I8 of arcuate cross-section and adapted to receive the head I5 of the needles I5 of bar I I.
  • the heads I5 also are provided with a groove IS, the two needle bars 8 and i i may be interchanged in operation.
  • brackets I8 and I I are upwardly dis placed from the brackets I8 and I I in order to disengage the nooses of the zig-zag thread still hanging at their rear ends on the sliding needles 2 from the latter.
  • the needle bar 9 then is again set in the brackets I and I I, and the ware I3 then is situated on the carrier I as shown in Fig. 2.
  • the needle bar It then is inserted in the brackets I6 and II, the heads I of it needles I5 being engaged to the heads I2 of the needles From such latter Since I2 of bar 9, as shown in Figs. 3 and 4.
  • the ware I3 now is transferred from the needles I2 onto the needles I5 by throwing it forward accordingly.
  • the needle bar I4 together with the ware I3 hanging therefrom in front, is taken from the brackets I6 and I? and inserted in the brackets I0 and I I on the carrier I, after the needle bar previously lodged therein has been removed therefrom.
  • the slide 3 which still is at the right of the carrier I, then is returned to its starting position, the sliding needles 2 through the cam face 3 being advanced with the aid of the supple element 5 for the purposeof forming the trick.
  • the freely available working thread which now is at the right of the ware I3, then is inserted in the trick from right to left, and in this direction the slide 4 also has to be moved for the purpose of continuing the knitting cycle.
  • the ware I3 in this manner shows to the operator one side of the plain hosiery, while on the rear side the other side of the plain hosiery is produced. Such knitting cycle may be repeated as desired for producin fresh rows of loops.

  • Figs. 5 and 6 illustrate the details of a removable mounting of bracket II.
  • reference numerals refer to similar elements as in the other figures.
  • Numeral I'I designates a support bracket, the foot of which has two head pins I9 that engage in slots 20 of a mounting plate 2
  • the slots 20 are widened at one end so as to permit insertion of the headed pins IS, the heads of which consequently bear against the mounting plate 2I when the brackets I! are mounted.
