Definitions

  • the latch needles are arranged so that when the hooks of the receiving needles in one bed are inserted into the transferring needles of the other bed the spoons of the pivotable latch members which normally close the hooks, strike abutment surfaces formed on the transferring needles thereby pivoting the latch members away from the hooks to open the hooks.
  • This invention relates to latch needles for knitting machines, and has reference particularly to such needles of the kind adapted for use in the transference of stitches from needles in one bed to needles in an opposed bed of a knitting machine, e.g. of the fiat V-bed type.
  • An object of the present invention is to provide, in and for a knitting machine having opposed needle beds, improved latch needles of the kind herein referred to designed to obviate the aforementioned disadvantages and permit of the smooth transference of stitches by such needles alone, i.e., without assistance from any auxiliary latch-influencing devices.
  • a knitting machine having opposed needle beds which are angularly disposed with respect to one another and are equipped with latch needles of the kind adapted for transference of stitches from needles in one bed to needles in the opposed bed, said machine being characterized in that the latch needles are so formed and operable that when hooks of receiving needles in one bed are inserted into the transferring needles in the other bed, the spoons of the pivoted latches of the said receiving needles strike abutment surfaces or edges provided on the transferring needles so that these latches are swung over rearwards to open the hooks of the receiving needles.
  • the knitting machine includes a latch needle characterized in that a V-shaped notch is formed in the rear of the needle stem at a location between the needle hook and a lateral stitch transfer recess formed in a relevant side of the said stem.
  • a hook guide channel is also formed in the rear of the needle which opens into the said recess and which is narrower than the spoon of the needle latch of a receiving needle such that a flank of the V-shaped notch interrupted by the aforesaid channel acts as an abutment surface or edge adapted to strike the latch spoon of a receiving needle inserted into the guide channel.
  • FIGURE 1 is afragmentary detail view, partly in section, of portions of two opposed needle beds of a V-bed fiat knitting machine and illustrates the initial stage of a stitch transferring operation during which the latch of the receiving needle is about to be turned back to permit of insertion of the hook of that needle into a stitch which is to be surrendered by the opposed transferring needle,
  • FIGURES 2, 3 and 4 are views similar to FIGURE 1 depicting successive further stages in the said stitch transferring operation
  • FIGURE 5 shows, on a greatly enlarged scale, the relevant parts of two needles co-operable in such a stitch transferring operation
  • FIGURE 6 is a cross-section taken on the line VI-VI of FIGURE 5.
  • each of the latch needles in both beds is formed a hook guide channel 5 of the known form and disposition hereinbefore described.
  • the guide channel 5 of each of these improved needles opens into and is thus in communication with a V-shaped notch 6 which is milled into the rear R of the needle.
  • the flank 6 of the notch 6 in a transferring needle facing the hook 1 of a receiving needle has a continuous and solid surface whereas the other flank 6 of the same notch is interrupted by the hook guide channel 5.
  • this channel 5 is narrower than the spoon 3 of the needle latch 2. Accordingly, when the hook 1 of a receiving needle is inserted and advanced into the channel 5 of a transferring needle (FIGURE 5) the spoon 3 of the receiving needle strikes the flank 6 of the notch 6 in the rear of the transferring needle which flank functions as an abutment surface or edge. Consequently, as the transferring needle advances, the latch 2 I of the receiving needle is rotated or turned over backwards in the direction of the stem of the last mentioned needle by contact of this abutment surface 6 with the spoon 3.
  • the abutment surface 6 of the transferring needle engages the tip of the latch 2 of the receiving needle, the point of engagement being thus located at a maximum possible distance from the pivot of the said latch: the turning over of this latch is thereby enabled to take place slowly and smoothly.
  • each latch needle is extended to a point as close as possible to the lateral recess 4 which interrupts it to ensure that the hook of the receiving needle when the latter is advanced is inserted beneath a stitch supported on the shoulder St and extending across the adjacent recess in the transferring needle.
  • each of said needles including loop support means located on the upper surface thereof for holding a loop in the delivery position thereof, a loop transfer notch formed in the needle shaft rearwardly of the loop support means,
  • a guide channel for the needle hook of the corresponding loop receiving needle formed in the lower surface of the needle shaft and opening into said loop transfer notch and means for providing opening of the needle hook through action of the needles themselves, comprising at least one abutment surface formed in the needle shaft located forwardly of the loop support means between the needle hook and the loop support means and beneath the upper needle surface for abutting against the spoon of the needle latch upon insertion of the needle hook of a receiving needle into the transfer needle and for causing pivoting of the needle latch upon further forward movement of said receiving needle to cause opening of the needle book.
  • saidabutment surface comprises a V-shaped notch formed in the needle, the width of said channel being less than the width of the spoon of the corresponding latching needles so that the edges of the V-shaped notch act as an abutment surface for abutting with said spoon and w pivoting the latch member of said receiving needle when said receiving needle is inserted into said channel.
  • a knitting machine as claimed in claim 2 wherein the portion of said needle forming said guide channel extends as close as possible to the loop transfer notch.
