Definitions

  • the present invention relates to improvements in loop lifting implements for knitting machines
  • the heel tabs and ravel sole courses are knitted.
  • a feature of the invention consists in the provision of a loop lifting implement arranged for removing and for returning loops to the needles, .Whichis provided to the side thereof with the previously knitted loops of the fabric with an indentation adapted for engaging therein the head portion of the previously formed loop in order to support the terminal loop held on-the loop lifting implement over the point .of the implement;- i
  • Fig. i is a'side'elevation of a loop lifting implement embodying in .-a preferred formthe several featuresvof 'applicants inven- 'tion;
  • Fig. 2 is a front elevation of the loop lifting implement shown in Fig.1; Figs.
  • 3 to 8 inclusive are a series of somewhat diagrammatic views illustrating the relative positions of the loop liftinginstrumentalities arranged for supporting instep loops together with the cooperating needles, sinkers and webholder elements during the successive-steps in the return of these loops and the needle cooperating therewith during the transfer operation, and corresponds'to the position of these parts illustrated specifically in Fi 7.
  • Applicant's improved loop lifting point is herein specifically illustrated and described in connection with a, multiple section full-fashioned knitting machine adapted for knitting a complete foot and leg hosiery blank, the implements illustrated 'being employed specifically for the purpose of removing the terminal loops comprising the instep portion .of the fabric from the needles, and for holding these loops during the knitting of the heel tabs and sole ravel courses, and there after'for transferring these loops back to the instep needles preparatory for the knitting of the foot portion of the fabric.
  • the notched portions ll are made sufficiently shallow to permit the needle tip to pass beneath a bar of yarn in the groove provided by the notches l4 during the operation of returning the loops to the needles.
  • Applicant illustrates in Figs. 3to 8'inclusive, the usual cooperating knitting instrumentalities in a full-fashioned knitting machine including the needles l8, sinkers 20 and knockover bits 22.
  • the operation of applicant's improved loop lifting implements when employed to remove and support the instep needle loops to the backs of the needles during the knitting of the heel flaps and sole ravel courses, and to thereafter transfer said loops back to the needles, may be briefly described as follows:
  • the implements cooperate with the needles in the usual manner to engage upon the points and to raise the lifted loops above the tips of the needles.
  • the needle loops placed in their usual position on the shanks of the loop lifting points as, for instance,. in an ordinary narrowing operation, are located substantially opposite or above the notches ll. Owing to the tightness of the needle loop with relation to the cross-sectional area of the loop lifting implement,
  • the tips of the needles moving relatively upwardly with relation to the loop lifting implements and pressed in the usual manner into the hollowed or grooved portionrof the implements will pass under the bar of yarn formed by the needle loops of the previously knitted course, so that these bars of yarn will be forced out of the notches 14 during the continued relative movement of the needles and points as shown in Fig. 10, thus freeing the points from the fabric and permitting their removal as specifically illustratedin Figs. '7 and 8.
  • the bevelled portions ii of the notched walls of the implements serve to provide an adequate clearance to prevent possible catching of the viously knitted loop into the indentation, and thus to prevent the inadvertent losing of the loops from the points.
  • a pointed 100p lifting implement having a shank portion and a needle receiving groove in the shank, and a yarn engaging notch formed in the grooved side of the shank.
  • a pointed loop lifting implement having a needle receiving groove, and an undercut yarn retaining notch formed in the grooved side thereof.
  • a loop lifting implement having a shank portion and a needlereceiving groove in the shank portion and a notch formed in the grooved side of the shank portion for engagement with fabric loops with the edges of the notches during I vertently slipping off over the tips of the points.
  • the notches H are rendered inoperative by the location of the needles in interlocking .engagement with the points.
  • notched portion 14 is illustrated as 'a :hook to engage with and positively support a bar of yarn formed by the needle loop of the previously knitted course
  • the invention in its broader aspects is not limited to any specific form of this indentation which depends in large part for its effectiveness upon the tendency of the fully stretched terminal wale loops to draw the bar of yarn comprising the prethe bar of yarn formed by the needle loop of the previously knitted course to maintain the transferred needle loop firmly on said implement.
  • a loop lifting implement having a shank portion and a needle receiving groove in the shank portion, and a notch formed in the grooved sideof the shank portion for engagement with the bar of yarn formed by the needle loop of the previously knitted course to maintain the transferred needle loop firmlyon said implement, and said notched portion being sufficiently shallow to permit the needle tip to pass beneath said bar of yarn in the groove during the operation of returning the loop to the needle.
  • side walls having the outer edges thereof bevelled inwardly to facilitate the removal ofvthe implement subsequent to the return of the loop to the needle.
  • a loop lifting implement having a shank portion and a notched portion extending transversely in the shank portion of the implement and located to that side of the loop lifting implement with the previously formed loop from which the lifted loop depends.
