Definitions

  • ABSTRACT Pattern jacks in a multi-feed circular knitting machine are accommodated in a cylinder c o-axial with but of a larger diameter than the needle cylinder. Jack butts are set out in diagonal lines. At each feed there is a slotted block housing a vertical bank of superimposed pairs of jack selector tuck and knit slides having cam faces upwardly sloping to two different extents heightwise. Springs urge selector slides into operative positions, slides being selectively held withdrawn clear of jack butts against the biassing influence. Movements of jacks imparted by slides are less than sufficient to raise corresponding needles to heights required. Thus movement transmitting and amplifying levers are provided between the jacks and the needles.
  • each slotted block is a removable toothed programme comb having some teeth reduced in length and others broken away, according to pattern. Teeth act on projections on slides to hold them back. Jacks are either not raised or are raised to one of two heights to cause needles to miss, tuck or knit depending on the layout of teeth, half teeth and gaps on and in the programme comb.
  • the selective action of. the pattern jacks is for the purpose of exercising such selective individual control over the needles that whilst predetermined ones are permitted to remain down and non-knit, others are raised, e.g. either to clearing height so that they knit, or to an intermediate height so that they tuck, all according to knitting requirements.
  • the patterning butts on the pattern jacks, one butt per jack in a machine of the kind concerned are commonly so disposed in a multiplicity of superimposed planes as to enable the butts in any one horizontal plane to be well spaced apart circumferentially: in such an arrangement, the butts on successive jacks are so relatively offset laterally in the superimposed planes as to be in echelon formation rightaround the machine, -i.e. to present circumferentially spaced and parallel lines of butts extending diagonally, the lateral offsetting corresponding, of course, with the pitch of the jacks circumferentially of the machine.
  • diagonal lines of butts instead of extending all in the same direction parallel to one another, to extend alternately in opposite directions suchwise as to meet in a succession of VS. Or a combination of diagonal lines and VS may be adopted.
  • the invention shall be applied to a circular multi-feed knitting machine of the rotary needle cylinder type, in which instance the individuallyoperable needles and their actuating pattern jacks move round with the knitting head, whereas the banks of prearranged jack selector slides are associated or combined with the stationary cam box or shell surrounding the needle cylinder.
  • the object of the present invention is to provide, in a multi-feed circular knitting machine of the kind herein referred to, a generally improved arrangement of the patterning mechanism designed'substantially to increase the patterning scope of themachine whilst at the same time enabling the axial dimension of the needle cylinder to be keptto-a minimum.
  • the patterning mechanism comprises, in combinationz pattern jacks which are accommodated in tricks formedina'separate jack cylinder which is-co-axialwith, but of a larger diameter than, the needle cylinder,the patterning butts on these jacks being set out in diagonal lines as aforesaid but with the vertical pitch of said butts reduced to such an extent that liftingmovements imparted to'the pattern sponding needles to the heights required; means for transmitting to the needles and simultaneously amplify-v ing the lifting movements imparted to the pattern jacks by the slides; slotted blocks each for accommodation of one of the vertical banks of jack-selector slides in each of which blocks the selector slides are arranged in superimposed pairs respectively opposite the planes of pattern jack butts, with the two slides of each pair disposed side by side and constituting tuck and knit slides with operative noses having cam faces upwardly sloping to respectively different extents heightwise; springs within the slotted blocks urging the
  • corresponding pattern jacks with patterning butts at that level will either not be raised, or only partially raised or fully raised to cause the relevant needles to miss, tuck or knit respectively.
  • each slotted block is itself in the nature of a mechanical patterning unit of a kind which, when once set by the insertion of a programme comb to produce a desired pattern, requires to be re-set manually by removal of the comb and insertion of a fresh comb before another pattern can be produced.
  • the programme comb is, in effect, a pattern key the predetermined form of which may vary practically infinitely depending on which teeth are reduced in length and/or which are broken off.
  • the slides are not themselves selectively operated under control, and when once the pairs of knit and tuck slides in any one of the slotted blocks have been fixed in the required positions, by insertion of a programme comb, they remain in these positions for a run of theknitting machine and can only be changed by a change in the comb.
  • each tuckslideshall be adapted, by engagement with pattern jack butts at the relevant level, to lift deired pattern jacks only sufficiently far tocause corresponding needles, through the medium of the movementtransmitting and amplifying means to be raised to tucking height, whereas the upwardly inclined cam face of each knit slide, together with the cam face of the companion tuck slide, lifts pattern jacks to an extent sufficiently far to cause corrsponding-needles to be raised to clearing height and to knit.
  • the verticalpitch of the patterning butts on successive pattern jacks is such that the lower edge of the butt on any one jack is spaced vertically from the corresponding edge of the butt on the next jack a distance equal only to the overall vertical dimension of a single butt.
  • an individual jack can only be liftedbyany-one slide a distance equivalent to the vertical pitch of the butts.
  • the advantage of the invention is that by reducing this vertical dimension to a minimum, compatible with the practical minimum thickness of the jack selector slides, the number of such slides in each vertical bank, i.e. in each slotted block, can be a maximum calculated to maximize the patterning scope of the machine. And yet at the same time not only can the axial dimension of the separate pattern jack cylinder be kept within an economical limit, but an economically produced needle cylinder of comparatively small length can be used.
  • FIG. 1 is a general perspective view illustrating a few of the pattern jacks in the preferred form of the improved patterning mechanism as applied to a multifeed circular knitting machine of the rotary needle cylinder type, all but one of said jacks being shown in its lowered position, and the nose portions of one pair of jack selector slides, depicted in their forward positions, having just raised the relevant jack to knit height so that the corresponding latch needle is at clearing height having been raised to that position through the medium of the corresponding movement-transmitting and amplifying lever,

  • FIG. 8 is a similar detail plan view depicting both slides of the pair withdrawn, i.e. held out, and
  • FIG. 9 is yet another similar plan view showing both of the slides in their forward operative positions.
  • the illustrated multi-feed circular knitting machine comprises a rotary needle cylinder 10 which is axially tricked at 10a to receive individually slidable latch needles such as 11.
  • Each such needle is provided with not only a butt 1112 at its lower end for a purpose hereinafter to be described, but also with an upper needle-operating butt 11a adapted to be acted upon by knitting cams housed in a stationary annular cam box or shell surrounding the needle cylinder 10.
  • Pattern jacks 13, corresponding in number to the number of needles 11, are similarly accommodated intricks 14a formed in a separate jack cylinder 14 which is co-axial with, but of larger diameter than, the needle cylinder 10.
  • This plate is accommodated within a fixed plate 16.

  • Each pattern jack 13 has thereon a single patterning butt l3a, the said butts on successive jacks being so relatively offset laterally in a multiplicity of superimposed planes as to be in echelon formation right around the machine, i.e. in parallel, diagonally extending linesL'as shown in FIG. 1.
  • the jack selector slides 19, 20 are accordingly arranged in superimposed pairs respectively opposite the superimposed-horizontal planes of patterning butts 13a on the pattern jacks 13.
  • the two slides 19,-'20 of each pair are disposed closely side by side, as illustrated more clearlyin FIGS. 7, 8 and 9, and constitute tuck and knit slides with operative noses having cam faces 19a, 20a upwardly sloping to respectively different extents heightwise.
  • Springs 21 within the slotted blocks 18 urge the companion slides 19, 20 into their selected positions, and it is against the biassing influence of these springs that theslides 19, 20 are withdrawable to inoperative positions clear of the patterning butts 13a in the relevant planes.
  • the butts 13a on the pattern jacks 13 are set out in a multiplicity of superimposed horizontal planes equally spaced apart heightwise a distance d (FIG. 3) measured from the bottom edge of one butt to the bottom edge of the next adjacent butt, equivalent to the vertical pitch 'of the butts 13a.

  • the inner operative cam-like noses 19a, 20a of the slides 19, 20 are enabled to be inserted beneath the horizontal lower edges of butts and well into the spaces between butts as shown in FIG. 1.
  • Simple, radially extending movement-transmitting and amplifying levers 22 are provided, as shown in FIGS. 2 and 3, between upper rounded ends 13b of the pattern jacks 13 in the separate jack cylinder 14 and the lower butts 11b of the needles in the-needle cylinder.
  • the inner end of each of these levers 22 is recessed at 22a to receive the lower butt 1 1b of the corresponding needle.
  • the levers 22 thus extend across the annular space S between the two co-axial cylinders 10 and 14 of respectively different diameters and are located beneath the annular cam box or shell surrounding the needle cylinder 10.
  • each of the movement-transmitting and amplifying levers 22 is formed with a near-circular fulcrum 22b which is seated in a suitably formed ring 23 combined with the upper end of the pattern jack cylinder 14. To enable them to avoid interference with the jack cylinder 14,
  • the pivoted levers 22 are of upwardly arched form.
  • the upper rounded ends 13b of the pattern jacks 13 act upon the lower edges of the levers 22 at carefully predetermined points fairly close to the nearcircular fulcra 22b so that comparatively small lifting movements of the jacks l3 imparted by jack selector slides 19 or are magnified into substantially greater heightwise movements (such as a! FIG. 3) of the inner ends of the said levers.
  • each tuck slide 19 is provided with a lateral projection 19b arranged to move within a suitably elongated recess 20b formed in the adjacent side of the companion knit slide 20.

  • the jack selector slides 19, 20 are disposed in superimposed horizontal planes in which instance the cam-like noses at the inner ends of the slides themselves require to have upwardly inclined butt-engaging faces 19a, 20a.
  • the pairs of slides 19,20 of the vertical bank in each slotted block 18 may themselves be in parallel inclined planes with respect to the horizontal so that their operative noses can be in these same planes the angle of inclination being such as to impart to the jacks the required relatively small extents of lift.
  • each slide 19 may generally be opposite handed, viz. one lefthand and the other right-hand as shown.
  • each slide has a main front portion FP which, together with its cam-like operative nose 19a or 20a, protrudes through the front of the relevant slotted block 18, and a relatively slim rear or tail portion T? which protrudes rearwardly through the back of the block.
  • main front and the rear or tail portions FF and TP of each slide 19 or 20 are fashioned in one piece from the same material, it is preferred, on the ground of economy, to make the main front portion FP separately from and in a harder and more expensive material than the rear or tail portion TP and to rigidly connect together the two portions, e.g. by complementarily interengageable formations such as those shown in plan in FIGS. 7, 8 and 9.
