Definitions

  • knitted fabric is to be understood any fabric which is composed of or incorporates knitted or intermeshing thread loops.
  • the main object 'of the invention is to provide a knitted fabric wherein thetendency to rove or ladder is eliminated or minimized.
  • a knitted fabric wherein selected of the intermeshing loops extend through and also around or over other loops.
  • the thread loop which extends through and around another loop in accordance with this invention effects a looking or tying of one loop 1 upon another, and if in a knitted fabric embodying such locked or tied loops any unravelling or laddering should occur, this is efiectively checked by said loops which prevent or minimize any further tendency to unravel.
  • the thread loop which is locked or tied upon another loop may be constituted by a single thread or by a group of threads.
  • said thread may be the same as that constituting the knitted loops or stitches in the fabric.
  • the number of times a thread loop may be passed through and around another loop may be varied as desired.
  • Figure 1 illustrates a portion of plain knitted fabric incorporating locked or tied stitches in
  • Figure 2 shows similar fabric with a modified form of locked stitch.
  • Figure 3 illustrates onemethod of applying the invention to a. ribbed knitted fabric.
  • Figure t illustrates the invention applied to separate knitted chains and shows a weft thread 59 held in position
  • Figure 5 illustrates the weft thread being so incorporated as to constitute part of the locking means.
  • Figure 6 illustrates the g, vention to a warp fabric
  • Figure i1 illustrates a method of producing a simple loch stitch
  • Figure 8 shows the production of a modified lock stitch
  • needle loops a formed on selected needles each have a second loop b drawn therethrough
  • said needle loop is drawn through said second loop and retained on the needle.
  • the second loop b is drawn through and passed over or around the needle loop and becomes locked or tied thereon.
  • the second formed loops b are drawn through the needle loops a twice, this being accomplished by first passing the second loop I) through the needle loop a, then passing loop a through loop I) and finally again passing loop b through the loop a.
  • the locked stitches may be produced on selected needles of both the frame and machine needles or only on the needles of one set on selected courses.
  • the locked stitches occur only on one face of the fabric in any one course and the courses having said locked stitches on one face alternate at predetermined intervals with courses having such stitches on the opposite face, as illustrated in figure 3.
  • the invention is also applicable to knitted chains 0 ( Figures 4. and 5) the locked stitches being indicated at 11, said stitches being produced as before described by passing a loop of thread through and also over or around a thread loop just previously produced.
  • a fabric may be composed of a series of these chains simultaneously produced on separate needles, and the locked stitches d serve to grip in said chains weft threads such as shown at e laid in position by any known or suitable means.
  • weft thread e may be so laid upon the needles forming the knitted chains c as to be passed with the locking loops through and around the loops to be locked, said weft part of the stitch locking from the fabric in Figures 1 to 3 composed entirely of weft thread, i. e., thread extending weftwise from wale to Wale, it will be appreciated that the principle of stitch-locking is identical in all 5 cases. It is well known that if the same thread is fed at successive stitch-forming operations to the same needle a knitted chain-is produced, and machines which simultaneously make a series of such chains are also well known.
  • each chain so produced is in the fabric according to Figures 4 and 5, the equivalent of a stitch wale- 'in the fabric according to Figures 1 to 3 and the locking of a thread loop or stitch in the chain fabric is accomplished by passing a thread loop through and also around the loop to be locked.
  • the traversing of theweft e by any known or suitable thread-traversing means is so timed as to cause such weft either to be embraced by the chain stitches without actually forming partof the stitch-lock as in Figure 4, or so as to be associated with and form a part of the stitch-lock as in Figure 5.
  • Figure 6 is shown one method of applying the invention to a warp knitted fabric which is 25. of a type well known to those versed in the art of knitting and is composed of warp threads f which aretraversed laterally to the extent of one needle in opposite directions on successive courses, the locked stitches which are here indicated at 9 being produced in the manner hefore described.
  • the invention is in no way restricted to the types of fabric before described but is applicable to any fabric embodying intermeshing or knitted loops.
  • the whole or selected of the needles employed may be provided with a plurality of pivoted latches spaced one below the other on the same side of the shank.
  • two latches may beprovided in which case when the lowermost latch is fully raised its extremity bears upon and slightly overlaps the upper latch in its down position.
  • Figure '7 is shown the production of a locked stitch as illustrated in Figure 1.
  • the needle is raised to a height suitable for clearing the previously formed needle loop a to a position below the lower latch h and to permit of new thread b being fed between the two latches h, 13.
  • the lower latch h is pivoted upwards and bears at its end upon the end of the downturned upper latch 12, the old loop a passing over the two overlapping latches into the hook of the m needle.
  • the new loop b to close the upper latch i, said loop being cast off while the old loop a is retained in the needle hook.
  • the needle loop I) is first drawn through the'old loop a as shown in 7 the second position in Figure 7 and then passed around same as shown in the final position thus tying itself upon said old loop.
  • FIG 8 The production of the locked stitch shown in Figure 2 is illustrated in Figure 8.
  • a needle with three displaceable latches is provided, the middle latch h and lowermost latch 11' being each adapted when in their fully raised position to abut against and slightly overlap the latches disposed next above.
  • the function of the needle is in this case similar to that before-described, the needle being elevated to such position that the .old loop a passes beyond the lowermost latch 7' and new thread I) is laid on the shank of the needle between the middle and lower latches h, 7'.
  • the lowermost latch a On the firstipart of the downward movement of the needle the lowermost latch a is reversed to abut against the middle latch 71. and the old loop a guided overthe abutting latches and the newly laid thread I) covered thereby,: and passing toward the shank of the needle between the upper and middle latches i and It.
  • the middle latch h On further downward movement of the needle the middle latch h is reversed by the newly laid thread loop b and abuts against the uppermost latchi.
  • the newly laid loop is thereby guidedover the abutting latches h, 1' covering the old loop a and passes toward the hook of the needle; the old thread loop a subsequently reverses the uppermost latch i and is thereby cast offthe needle.
  • each of selectedstitch loops composed of knitting yarns is locked or entwined bya knitting yarn which passes around the one 120 side bar of said loop, then across the loop and finally around the opposite side bar of. said loop.
  • a fabric embodying a plurality of intermeshing thread loops of knitting yarn, selected of said loops-extending through other loops and around the legs thereof, whereby said selected and other loops are locked or intertwined with one another, and said selected loops being composed of different yarn from the other loops.
  • a knitted fabric comprising knitted chains each consisting of intermeshing thread loops and each of selected of said loops passing through a preceding loop in the same chain and also embracing or encircling said preceding loop to lock the'latter.
  • a knitted fabric comprising knitted chains, each chain consisting of intermeshing thread loops, each of selected of said loops passing through a preceding loop in the same chain and also embracing or encircling said preceding loop to lock same, and a weft thread extending across said chains, said weft thread being gripped in the chains by the locked stitches.
  • a knitted fabric comprising knittedchains, each chain consisting of intermeshing thread loops, each ;of selected of said loops passing through a preceding loop in.the same chain and also embracing or encircling said preceding loop to lock same, and a weft thread extending across the chains and gripped therein by thelocked stitch loops and said weft thread constituting part of the stitch locking means.
