Definitions

  • a patterning chain furnished with planar studs selectively acting upon jacks in a mechanism controlling the run-in of selected warp ends in a warp -knitting machine.
  • the chain comprises parallel spaced pins adjacent pairs of 'which are connected at their ends by links, each pin having therein axially spaced annular grooves in line with the selector jacks.
  • Each pattern stud retained on a pin by a spring clip, has therein two recesses enabling it to be fitted upon aligned grooved portions of two adjacent transverse pins.
  • a warp knitting machine having patterning mechanism which is arranged to control the rate of run-in of the warp ends thereby to produce patterned Warp knitted fabrics.
  • the machine may be used to perform a method, also described and claimed in the aforementioned complete specification, of producing a fabric which is patterned by predetermined dispositions therein of false spots produced by controlling the rate of run-in of selected Warp ends by the patterning mechanism.
  • the machine described in the complete specification aforesaid may also be employed to effect a method of producing a patterned 'warp knitted fabric which is knitted of two contrasting yarns merged to create a background and wherein at predetermined locations upon this background there are raised loop effects produced by varying the run-in of selected Warp ends of one or the other of the said two yarns.
  • the present invention is concerned exclusively with the provision, in or for a warp knitting machine, of patterning mechanism arranged to control the rate of run-in of the Warp ends to produce patterned wvarp knitted fabrics.
  • the patterning mechanism described in our prior U.S. patent aforesaid comprises a patterning component in the form of a chain which passes around a toothed drum and is furnished with pre-arranged lugs, studs or like elements.
  • the object of the present invention is to provide an improved patterning mechanism including a chain having elements lwhich can be readily mounted thereupon and readily detached therefrom.
  • the patterning mechanism according to this invention is characterised by a patterning chain comprising, in com- ICC bination, a plurality of pins extending parallel to one another transversely of, and regularly spaced apart along, the length of the chain, the ends of adjacent pairs of pins being connected by articulated links and the said pins having formed therein annular grooves spaced apart axially therealong, i.e.
  • a plurality of pattern elements mounted in predetermined positions upon the chain and each consisting of a cam plate having a profiled edge upstanding from the chain and in which there are two recesses enabling the element to be -tted in position upon aligned annularly grooved portions of two adjacent transverse pins; and spring clips securing and retaining the said pattern elements in position upon the relevant pins.
  • cam elements will be referred to as pattern studs, albeit that each of them is preferably in the form of a suitably profiled plane cam plate.
  • the pattern studs can be expeditiously mounted upon the chain in predetermined positions in which they are positively retained by means of the spring clips. Conversely, whenever the positions of some or all of the pattern studs require to be changed, the relevant spring clips are released to permit of removal from the chain of the corresponding pattern studs. The removed studs can then either be left olf the chain or, if still removed, can be readily placed and retained in their new positions.
  • each pattern stud defining the first recess therein is prevented from moving perpendicularly with respect to the chain by virtue of the fact that, when the stud is turned into its position of use, the portion thereof at one side of this recess will be located at the underside of, and hooked beneath, the relevant pin, at the inner side of the chain. Moreover, any movement of the pattern stud relatively to the chain in the longitudinal direction thereof is prevented by engagement of that portion of the stud having therein the second recess with an annularly grooved and thus reduced portion of the adjacent pin.
  • the spring clip of each pattern stud is fitted at the inner side of the chain to close the second recess and thus prevent the stud from turning and moving perpendicularly with respect to the chain. In this lway, removal of pattern studs from the chain is positively prevented.
  • the two recesses in each stud are formed in adjoining edge portions thereof and extend at a right angle or substantially so to one another suchwise that when the stud has been mounted in its required position the rst of said recesses extends in the longitudinal direction of the chain whereas the second of the recesses extends perpendicularly to the chain.
  • the stud is then turned in its own plane for approximately in a direction to bring the portion of the pattern stud defining the second recess therein into the aligned annular groove in the next adjacent transverse pin so that the relevant reduced portion of the pin is received within the second recess. That is to say, the portion of the stud defining the second recess therein straddles the last mentioned reduced pin portion.
  • each of the transverse pins of the chain may advantageously be reduced, these reduced ends extending through complementary holes in the links and having formed therein narrow annular grooves adapted to receive generally U-shaped spring clips Whereby the links are retained in position as in a conventional roller chain.
  • FIGURE 1 is a side elevational view of a pattern drum around which patterning chains of the improved form are passed, and showing also selector jacks operable by pattern studs on the said chains,
  • FIGURE 2 is a side view of fragmentary portions of a jacquard frame illustrating mechanism adapted for use in conjunction with a warp loom for interfering with the controlled run-in of selected warp ends,

  • FIGURE 7 is a detail side view or one of the pattern studs
  • FIGURE 8 is a rear view of such a stud with a securing clip engaged therewith
  • FIGURE 9 is a detail perspective View of one of these clips per se.
  • FIGURE 10 is a side view of one of the chain links
  • FIGURE 1l is a side view of one of the spring clips used to retain the links in position upon the ends of the annularly grooved transverse pins.
  • the illustrated patterning assembly includes a rotary pattern drum 1 which is provided therealong with axially spaced chain sprockets 2 and is thereby adapted to constitute a chain support.
  • the particular drum shown is designed to carry three identical chains arranged side by side.
  • the pattern drum 1 is mounted to rotate in suitable bearings in side frame members 3 of a drum housing H, and is adapted to be driven from a driven shaft 4 through the medium of a train of change speed gears such as 5, 6, 7, 8 etc.
  • the shaft 4 is provided with a chain sprocket 4a, thereby adapting it to be chain-driven from any appropriate power source.
  • FIGURE 5 Small portions of two of the three chains are indicated at C1 and C2 in FIGURE 3 Similarly, a fragmentary portion of another of these chains is represented at C3 in FIGURE 1.
  • the actual chain construction is shown more clearly in FIGURE 5.
  • Each such chain has tracks for sixteen pattern studs such as 9, so that the three chains can have studs mounted thereon at any desired ones of forty eight positions across the combined widths of the chains and at any desired positions along the lengths of the latter.
  • Each of the three chains C1, C2 and C3 comprises a plurality of transverse pins 10 of mild steel having reduced ends 10a (FIGURE 6) which enter complementary holes 11a in at links 11 (see FIGURE 10) connecting the ends of adjacent pairs of such pins. These links 11 are retained in position upon the ends of the pins 10 by U-shaped spring clips 12 engaging in annular grooves 10b formed in the reduced end portions 10a of the adjacent pairs of the rods.
  • Each of transverse pins 10 is formed with two groups each of eight annular grooves 10c of identical dimensions located at regularly spaced intervals therealong and thus providing sixteen reduced portions 10d.
  • cach transverse pin 10 has thereon three widely spaced portions 10e of the full diameter of the initial rod from which the pin was formed; these three portions 10e of each pin 10 are so axially spaced and dimensioned as to be capable of engaging in spaces S between the teeth 2a on the three chain sprockets of the relevant group. That is to say, as the pattern drum 1, gear-driven from the shaft 4, rotates successive ones of the linked transverse pins 10 of the three side-by-side chains C1, C2 and C3 engage in successive spaces S between the teeth of the chain sprockets 2 of the three groups G1, G2 and G3 respectively.
  • Each of these studs comprises a plane plate having, as shown in FIGURE 7, a basically square portion 9a adapted to be fitted within the relevant chain and an :adjoining trapezoidal portion 9b tapering to a short edge 9c and constituting the cam portion of the stud.
  • the convergent edges of the portion 9b merge With the ends of the short edge 9c to provide smooth passage of the cam portion over the members to be controlled.
  • Formed in the rfront edge of the stud constituting one side of the square portion 9a thereof is a first recess 9d of a shape and size to fit over and receive a reduced portion 10d of a transverse pin 10.
  • each stud 9 In the edge constituting the adjoining side of the square portion 9a of each stud 9 is a second recess 9e of the same width as the recess 9d but somewhat deeper than the latter.
  • the recess 9e has an arcuately flared entrance 9f, the centre of curvature of which is coincident with the centre of the first recess 9d.
  • the first mentioned recess 9d is engaged with a selected one of the reduced portions 10d of a transverse pin 10 ⁇ so that the portion of the stud defining that recess straddles the said reduced portion, with the stud extending lengthwise in the direction of length of the chain as depicted in FIGURE 5.
  • the plate-like stud is then turned through approximately in the relevant direction about the reduced portion 10d to bring the other recess 9c into engagement with the aligned reduced portion 10d of the adjacent transverse pin 10.
  • the pattern stud 9 is now disposed in its position of use with its length, i.e. heightwise dimension, extending perpendicularly with respect to the length of the chain.
  • each of these clips 13 is in the form of a longitudinally split spring metal tube; this tube is of almost circular cross-section but has therein a narow slot 13a of varying width extending longitudinally from end to end thereof.
  • the longitudinal edges of the tubular clip 13 flanking the slot 13a are slidably engaged in the V-section grooves 9g and under the action of the inherent resiliency of the said clip the edges grip the grooved portions of the stud.
  • the opposite ends of the slot 13m are of increased width, so that the intermediate opposed portions of the clip flanking and defining the intermediate section of the slot are closer together than the end portions suchwise as to form shoulders 13b at the opposite ends of these intermediate portions.
  • the clip 13 is slid axially olf the stud, the intermediate portions flanking the narow portion of the slot being forced apart so that the clip can be removed.
  • the stud is then turned in the opposite direction to that in which the stud was turned when being applied to the chain and can then be removed from the chain and, if required, replaced in a new position.
  • a patterning mechanism incorporating the three pattern chains C1, C2 and C3 are suitable for practising the dragging thread technique will now be described with reference more particularly to FIGURES 1, 2, 2A, 3 and 4. It lis. considered unnecessary to illustrate any of the warp knitting loom-apart from a portion 14 of the framework thereof by which the patterning mechanism is carried (see FIGURES 2 and 4).
  • the mechanism now to be described is very similar to that disclosed in United States Patent No- 3,063,272, to which reference may be made, and is based on the fact that a reduction of the normal rate of run-in of selected warp ends can be effected by temporarily lifting the said ends in a controlled fashion at points between the source of the Warp supply (not shown) and the needles of the loom.
  • the brackets 15 At their lower ends the brackets 15 have attached thereto a horizontal rail 18 of hollow section combined with strips 18a drilled to receive, and function as guides for a longitudinal series of vertically disposed and slidable warp and lifting hooks 19 of the double-headed form shown in FIGURE 2A.
  • Each hook 19 ⁇ is adapted to receive a predetermined warp end or two or more of such ends, according to requirements. Although this is of little importance so far as the present invention is concerned there are, in fact, two parallel series of the lifting hooks 19 for engagement respectively with two sets of warp ends threaded through the front guide bars of the loom.
  • each lifting hook 19 is attached to the lower end of a length of nylon cord 20l constituting a exible drive-transmitting element.
  • the upper end of each nylon cord 20y is, as shown more clearly in FIGURE 2A, formed with a loop which is engaged with a locking screw 21 serving to secure a sleeve 22 in an axially adjusted position along a horizontal actuating rod 23.
  • the rods 23, which are freely shiftable horizontally, are supported by and guided in appropriate members of the structures 16.
  • each nylon cord 20 extending from the corresponding locking screw 21, is passed over a grooved pulley 24 and from thence extends vertically downwards.
  • cords 20 at one side of the mechanism are represented in full lines, whereas cords at the opposite side of the mechanism for attachment to a set of actuating rods similar to those shown are represented in dotted lines.
  • the pulleys 24 of each of the two groups involved are rotatably mounted on an inclined support member 2'5 ⁇ of the structure 16. The constructions and arrangement are accordingly such that by moving any one of the actuating rods 23 longitudinally i.e. horizontally and laterally with respect to the loom, the lifting hook(s) 19 connected, through the medium of a cord(s) 201, with that particular yrod will be lifted vertically to engage and impart the required tension to the relevant individual warp ends.
  • the actuating rods 23 are movable longitudinally against the action of compression springs (not shown) and, when released, resume their normal positions under the spring action.
  • Tension rods (not shown) may be suspended beneath the rail 18 to determine the amount of tension in the lifted -Warp ends.
  • the hereinbefore described patterning mechanism with its three chains C1, C2 and C3 and pattern studs 9 in predetermined positions thereon is, of course, for controlling the actuating rods 23.
  • the chains C1, C2 and C3 may be of any appropriate length to provide a practically unlimited patterning range.
  • the selector jacks 27 are in the form of bell-cranks which are fulcrumed upon a jack support shaft 28 fixed at its ends in the side frame members 26 of a pivoted subsidiary frame SF mounted upon top of the pattern drum housing.
  • the said jacks there are three groups G4, G5 and G6 each comprising sixteen jacks in two sets of eight to correspond respectively with the sixteen pattern stud tracks (two eights) of the corresponding pattern chainall as seen in FIGURE 3.
  • the horizontal limb 27a of each selector jack 27 is furnished at its outer end with a small roller 28 to be acted upon by the cam portions 9b of any pattern studs 9 in the corresponding stud track.
  • each jack has attached thereto a Bowden cable 29 which, after passage through a cable support bar 30 fixed to the subsidiary frame SF, extends across to the structure 16 and thence through adjustable tubular guides 31 fixed by lock nuts 31a in members such as 32 of the said structure, Finally, the cables 29 are attached to the relevant ends of the actuating rods 23 by means of screwthreaded attachment devices 33.
  • Spacing bars SB are arranged between the groups of selector jacks 27.
  • a stop bar or rod 34 which is adjustable back and forth by manipulation of screws 35 and is arranged to determine the normal inoperative positions of the jacks 27. That is to say, when a jack is inoperative, the front edge of its vertical limb 27b is in contact with the stop bar or rod 34; thus is the position to which a Jack, after moving 0E a pattern stud 9, automatically returns to release the corresponding actuating rod 23 and permit it to return to the right (as seen in FIGURE 2) under spring action.
  • the stop bar or rod 34 enables the profile of the pattern studs 9 either to be fully used to lmpart maximum turning movement to jacks or to be only partly used.
  • the stud 9 is about to make contact with the roller 28 on the jack 27 at a point which enables the full profile of the cam portion 9b of the stud to be used. Assuming that change gears were selected to produce an eight course false spot repeat, this would. be taken up as follows:
  • the subsidiary frame SF is pivotally mounted upon the top of the drum housing H.
  • a swing shaft 36 which is passed right through the frame SF, is engaged at its ends in bearings such as 37 (FIGURE l) mounted upon the housing H.
  • the lefthand sideV of the subsidiary frame SF has been omitted, as also has the bearing for the corresponding end of the swing shaft 36.
