Y.; said lPeterson assigner to said Smith Application August 18, 1938, Serial No. 96,6_32 l 12 claims. (Cl. 66-58) This invention relates to certain new and use movement from the level of the remaining nee ful improvements in a circular knitting machine and pertains more particularly to a machine for knitting the ribbed fabric portion of a sock. dles and jacks when the machine is positioned ' 5 stocking, or the like, with the wales in the two parts co-extensive. ‘ In one method of manufacturing socks or stockings of the class comprising a plain fabric portion and a ribbed fabric portion, the plain 1o fabric portion of the sock or stocking is knit on one knitting machine and then the ribbed fabric portion is formed on a second knitting machine comprising cylinder and dial needles. In trans ferring the plain fabric portion of the sock or 15 stocking to the second or rib knitting machine, only a portion of the stitches of the last course of the plain fabric is placed onto the cylinder < needles while the balance of the stitches are placed on transfer jacks mounted on the needle 20 cylinder and then these latter stitches are trans ferred from the jacks to corresponding dial nee dles of the knitting machine. In effecting this ' transfer of the stitches of the last course of the plain fabric to the circular knitting machine, 25 the stitches, insofar as we are aware, have -here tofore been picked by hand onto the cylinder nee dles and the transfer jacks with the result that this transfer operation has been a relatively - slow tedious and expensive. method of procedure. 30 The main object of this invention is to provide an improved mechanism for knitting a ribbed fabric onto a plain fabric. A more specific ob to receive the formed stitches.- Another object_of the invention is to provide a rib knitting machine with simply constructed _ 5 and operated means for bringing the upper or outer ends of all of the cylinder needles and transfer jacks to a uniform predetermined level and positively holding them _at said level. ' A further object oLthe invention resides in 10 providing a knitting machine of the above men tioned class with simple and eñlcient means for transferring the stitches from the transfer jacks to corresponding dial needles of the machine whereby the wales in the ribbed portion of the 15 fabric will be formed co-extensive with those in the plain portion thereof. Another important object of this invention is to provide a circular knitting machine with im proved fabric feeding ortake-up means whereby. 20 the following advantages are obtained: First-the knitting machine may be success fully operated at a much higher rate of speed than is practical when using the well known con ventional types of i’eerl.4 ’ 25 Second-_only one setting of the feed means is required for different thicknessesor conditions of fabric, whether caused by use- of yarn of dif ferent weights or by use of different stitches as plain, rib'or cardigan. or when the stitches are Sii of different lengths. _ ‘ ' - . Third-the tension or strain upon the fabric ject of the invention is to produce a circular knit- ' incident to maintaining the same under operat ting machine for knitting to the plain fabric 35 portion the ribbed fabric portion of socks, stock ings, or the like, whereby all the last row of stitches of the plain fabric portion ma'y be sub stantially simultaneously transferred upon the cylinder needles and transfer jacks. j 40 In accomplishing the above mentioned object, we first knit the plain fabric portion ofthe ar ticle upon a flat knitting machine and then utilize a conventionally constructed transfer ring in transferringthe plain fabric to the cylinder 45 needles and transfer jacks ofthe rib knitting machine. Insofar as the applicants are aware, it is not practical when knitting stockings or the like by- the first method hereinbefore mentioned to utilize a transfer ring for directly placing the 50 loops of the last row of stitches of the plain ing tension during the knitting operation is re duced to a minimum. providing „themachine with simple and efñcient automatic yarn control means whereby two or more yarns of different or contrasting colors or materials may be selectively employed in the 40 . knitting of stockings or similar articles. A further object of this invention is to produce a circular rib knitting machine which is simple, » durable and' economical in construction and op eration. In carrying out this latter object, we 4s have produced a machine having but three cam tracks. one for the cylinder needles, one for the dial needles,V and one for the transfer Jacks. These cam tracks are separate and distinct from each other and Athe jacks and associated needles 50 fabric onto the cylinder needles and transfer always operatively engage in their respective, jacks of the rib knitting machine for the reason tracks andV are never transferred from one cam that certain of the cylinder needles, particularly track to another, thereby eliminating the ex pensive and intricate mechanism required when those adjacent the stitch and cast-olf cams are 35' _ - Still another object of the invention resides in 55 not supported against downward longitudinal „ effecting the movement of the cylinder needles ß À 2 8,187,382 or transfer jacks, or both, from one cam track to ' view taken on line 22-23, Figure 2, illustrating another as is often the case in machines of this the feed or take-up mechanism in elevation with a portion thereof broken away and in section. type. ’ Other objects and advantages will be brought out in the following description taken in con nection with the accompanying drawings in which: . - _ Figure 1 is an elevation of the right hand side of a rib knitting' machine embodying the various 10 features of this invention illustrating certain portions .thereof broken away and in section, the view being taken substantially in the plane of the line I--I, Figure 2. , Figure 2 is a transverse vertical 'sectional view taken substantially on line 2-2, Figure 1. ` Figure 3 is a side elevation of the upper por tion of the machine illustrated in Figures 1 and 2, showing the same viewed from the left hand side and with portions thereof broken away and in section. = Figure 4 is a detail horizontal sectional view taken on line 4-4, Figure 2.

As sociated with the cam track 51 are two pairs of ed at one end upon a stud 29 secured to a bracket 30 mounted upon the bracket l1. The arm 28 is connected by any suitable means to Vone end of a. spacer sleeve 3| rotatably mounted on studv 29 and which has secured to the opposite end thereof an arm 32 which has pivotally secured thereto as at 33 one end of a feed trip arm 34. The arm 34 extends inwardly or forwardly from the pivot 33 adjacent one face of the ratchet wheel `l5 and has the free end thereof supported by an annular ring or disk 35 secured to the ratchet wheel l5, as shown in Figure 1. The inner end of the trip arm 34 is so posi tioned relative to a tooth of the ratchet I5 when the pawl I4 is at the extreme end of its inward or feeding stroke that when said pawl I 4 is moved outwardly by the gear lil, the free end of the pawl will engage the trip arm 34 and be moved there by upwardly and be prevented from coming into movable cam members arranged at substantially diametrically opposite sides of the cam housing, each of which comprises a cast-olf or clearing cam 58 and a stitch cam 58. The cast-off or clearing cams 58 are arranged at the lower side of the cam track 51 and are each provided with 10.. ‘a boss or extension 60 which projects outwardly through an elongated slot 6I provided in the adjacent portion of the cam housing 50. In each extension 60 is mounted a. vertically dis posed r'ack member 62 which, in this instance, is 15 in the form of a rod, slidably mounted at the ends thereof in outwardly extending lugs or flanges 63 and 34 provided on the cam housing 50, as shown more particularly in Figures 1, 3 and 8.'

In other words, the chain ratchet 2l is moved forwardly one tooth space by the pawl 24 during each revolution of the gear I0, while the pattern I drum 20 is moved forwardly a distance corre- sponding to one to‘oth space of the feedratchet l5 only when a chain cam 21 engages the arm 28 for maintaining the triparm 34 out of en gagement with the feed pawl I4. ' ' Needle cylinder The rear portion of the bed plate 2 has mount .ed therein a ball bearing member 31- in which is mounted a vertically disposed drive shaft 38 which extends below the bearing 31 and has se cured thereto a pinion gear 39. Secured to the pinion gear 39 isa bevel gear 40 which is in mesh ing engagement> with a similar bevel gear 4I mounted upon the drive shaft 5. Rotatably mounted upon the bed plate 2 a short distance in front of the drive shaft 38 is a cylinder bear ing ring 43 which has secured to the lower face thereof a gear‘ring member 44 which is opera tively connected with the pinion 39 by means of 55 an intermediate gear 45 rotatably mounted upon astud 48 secured to the bead plate 2; see Figure 4. The bearing ring 43 also has secured thereto a needle cylinder 48 which extends upwardly therefrom in co-axial alignment with the bear ing ring 43 and ring gear 44. 'A cam housing 50 surrounds the needle cylinder 48 and is secured to the bed plate l2 in fixed relation therewith. The outer peripheral surface of the needle cylin der 48 is provided with a multiplicity of longi tudinally disposed grooves 5l arranged in uni form circumferential spaced relation for the re ception of thev cylinder needles 52 and transfer vjacks 53, the jacks in this instance.4 being ar ranged in every third groove, while the lneedles 70 are positioned in the grooves intermediate those in which the jacks are mounted.' In the upper portion of the interior of the cam housing 50 is mountedin ñxed relation there with a pair of ring members 55 and '56 composed 75 of hardened steel or the like, arranged in slightly ing. 50. The lugs 55 for the stitch cams 59 are. secured to a respective rack member 61 or 81' which extend vertically through corresponding openings provided in the lugs 63 and 64' respec tively, adjacent the upper and lower ends there of. Each pair of cams is operated independently 30 of the other pair of cams. and the cams of each pair are simultaneously moved in opposite direc tions to bring them into cooperative relation with the cam track 51 and with the butts of the cylin der needles 52 to eifect stitching and out of co 35 operative relation with said cam track and the needle butts -for transfer in a manner which will hereinafter more readily appear. . The means for operating the cast-off and stitch cams 58 and 59 located at the right hand side of ythe machine. as illustrated more particularly , in Figures l and 2, comprises a rack member. 69 mounted for longitudinal reciprocative movement in a groove 118 provided in the bed plate 2 be neath the cam housing 50. The rack 69 has a. push rod 1I connected at one end therewith and the other end of said rod is pivotally connected to one arm of a bell crank lever structure 12 which is rotatably connected intermediate 'its ends as at 13 to an upright bracket 14 secured to the bed plate 2. The other arm of the bell crank lever 12 extends rearwardly from the pivot 13 over the upper end of a push bar 15 which is mounted for vertical reciprocative movement in guide members 16 and'11 secured tothe bed plate 2 and bracket I1 respectively. The lower end of the push bar 15 terminates adjacent the 'pat tern drum 28 and is adapted to be operated by a cam >member 18 secured in any suitable manner to _the pattern drum 20 at one end thereof as illustrated in Figure 13. ` lThe bell crank lever 12 is yieldingly maintained in contact with the upper end of the push bar 15 by a coil spring 19 which also functions to yield ingly move the rack 68 forwardly when the bell Acrank lever is released- by the downward move _ment of the push bar 15 as saidfbar is released by the cam member 18. The rack 69 is in meshing engagement with-a pinion 80 rotatably mounted upon a shouldered 70 screw 8l secured to the adjacent portion of the cam housing 58 intermediate the adjacent rack members 62 and 31. A The pinion 80‘ is ,also in meshing engagement with a segmental gear mem ber 82 which is rotatably mounted upon a shoul 75 2,193,362 4 11 secured to the bracket member | 1, said push dered screw 88 secured vto the cam housing 58. The segmental gear member 82 also has meshing engagement with the racks 82 and 91 as illus trated in Figure 1, so that when the segmental bar being moved upwardly by a suitable cam member 98 mounted on the pattern drum 28. The upper end of the push bar-94 is adapted to engage gear member 82 is rocked about the pivot 88 a corresponding reciprocating movement of the one arm of a bell crank lever 96 which is rotat ably connected asat 91 with the _standard 3. The rack members 52 and 61 will be produced thereby for moving the cams 58 and 59 connected thereto toward or from the cam track 51. The mechanism for operating the other pair of cams 58 and 59 located at the left hand side of the machine is constructed and operated in the same manner as the mechanism just described for operating the cam members located at the right hand side of the machine with the excep tion that instead of the yrack member 69 engaging a pinion, it is in meshing engagement with a segmental gear member 85 rotatably mounted on a shouldered screw 88 secured to the cam housing 58 as shown in Figures 2 and 3. The segmental gear 85 in this instance is in meshing engagement with the rack member 81' connected with the adjacent stitch cam 59 for reciprocating the rack member and cam. Motion is transmitted from the rack member 51' to the companion rack mem-v ber 62 by means of a segmental gear member 82' pivotally -mounted intermediate its ends on a shouldered screw 81 secured to the cam housing 58. The remaining mechanism, as hereinbefore 30 stated, for operating the cast-off cam 58 and stitch cam 59 located at the left hand side of the machine, is constructed in the same manner as that previously described for the pair of cams located at the right hand side of the machine and, therefore, it is believed to be unnecessary to fur ther describe the construction and operation thereof. Jack ring The lower portion of the interior of the cam housing 58 is'provided with an enlarged circular recess 58' which extends inwardly from the lower end thereof to a position in close proximity to the lower positioned ring member 55 as shown in Fig 45 ure 2. In this recess 58' is mounted for axial movement a jack ring 89 which is of less axial length than said recess. The jack ring 89 is pro vided on its inner surface with a circular recess 98 which forms a uniform track for receiving the butts 53' of the transfer jacks 53 therein. The jack ring 89 is provided with a pair of dia metrically disposed cam slots. 9|, one of which is shown in Figure 18. These cam slots extend transversely of the jack* ring and receive therein 55 the end of a respective cam screw 92 which is mounted in the adjacent portion of the housing 58 in fixed relation thereto. 'I'he cam slots 9| are so arranged that when the jack ring 89 is rotated in one direction, said ring will be moved axially toward the ring members 55 and 58 for elevating the transfer jacks to bring them from the‘ inoper ative position withthe upper ends thereof in a -plane below the upper ends of the needle cylin ders 52 and when the jack ring is rotated in the other arm of the bell crank lever 96 is connected by a push rod 98 to a pin 99 which extends through a cam slot |88 provided in the adjacent portion of the cam housing 58 and has the inner end 10 thereof connected with the jack-ring 89, as illus trated in Figures 3, 18 and 19. The rod 98 is con nected with the pin 99 by means of a ball and socket joint, illustrated at |8|, Figures 2, 3 and 19. The cam slot |88 is disposed in angular rela 15 tion to the axis of movement of the jack ring 89 similar to that of the cam slots 9|, while the up per end as |88’ of the cam slot |88 and the lower ends 9|’ of the cam slots 9| are arranged to ex tend in a plane substantially normal to the axis 20 of movement of the jack ring so that when the ring is moved to its uppermost position, the pins l 92 and 99 will register in these horizontal por tions of the respective cam slots so that the jack ring will be maintained thereby in its uppermost position against being accidentally displaced by vibratory movement or other means. A spring |8| yieldingly maintains lever 96 in contact with push bar 94 and also produces rotation of the jack ring to lift the jacks carriedl by the ring 30 when push bar 94 is released by cam 93. As illustrated in Figure 2, the lower ends of the needles 52 terminate some -distance above the piane of the lower ends of the transfer jacks 58 and in each groove 5| containing a needle is 35 also mounted a needle jack |83 which has the butt |88' thereof positioned in the jack ring groove 98. 'I'he needle jacks |83 are similar in construction and each one 'extends upwardly a short distance beyond the upper edge of the jack 40 ring for engagement with the lower end of a cor responding needle when the jack ring is moved to its uppermost position, and when the ring is in its lowermost inoperative position, the upper ends of the needle jacks |83 terminate below the 45 needles so as to permit the free stitching opera tion of said needles', as illustrated in Figure 8. The distance from the butts |83’ of the needle jacks |83 to the upper end of said jacks is uni form for all of the needle jacks and this distance 50 is so proportioned‘relative to the construction of the transfer jacks that when the jack ‘ring is moved to its uppermost position, the needles 52 will be engaged by the needle jacks and main# tained thereby .with their upper ends at a prede termined uniform elevation. Operating mechanism for dial needles, The hereinbefore mentioned vertically disposed drive shaft 88 extends upwardly some distance 60 beyond the plane of the upper end of the cam housing 58 and needle cylinder 88 and extends through a gear case |85 secured to or made in tegral with a horizontally disposed dial support ing bracket or head |85 which is mounted inter 65 opposite direction, said ring will be moved axially mediate its ends upon the upper end of a guide downwardly away from the ring members 55 and 55 for returning the transfer jacks 59 to the post |81.

The upper end of the cani arm |58 is pivotally secured by a stud |58 to ' an L-shaped bracket |88 which has the shorter leg thereof secured to the bottom of the The other leg of the bracket ex tends downw-irdly adjacent the inner face of 55 gear case |85 a latch opener presently described. In order to cause the dial stitch cam |44 to function in this 8 manner, the push rod |51 is composed of two portions joined together by a turnbuckle |81 which is adapted to vary the'length of the rod | 51 and thereby vary -the relation of the cam |88 with pin |82. That is, when push rod |51 4 is adjusted to its maximum length, the cam sur face |88" will engage the pin |82 when rocker arm |55vis actuated by cam |58 for producing a maximum throw of the lever |48 to bring the dial stitch cam | 44 into its innermost operative 4 position. It will now be understood that by lengthening rod |51 by the manipulation of the turnbuckle |81, pin I 82 will be engaged by the cam surface |88' only which will produce a less degree of movement of lever, |48 when the arm | |55'is actuated by the cam |58 than formerly with the result that the dial stitch cam |44 will be moved to an intermediate position for ef fecting only a partial 'inward movement of the dial needles whereby the eyes of the needles will l be brought into operative alignment with the the cam arm |58 for maintaining said arm _ latch opener, presently described. The dial switch cam connected with lever |48’ against inward lateral movement during the cam is operatively connected with the pattern drum action thereof upon the stitch cam lever |48. The stitch cam lever |48 is provided with a pin cam |5| through the medium of a push bar |82 q 60 and a rock arm | 55, not shown, but which are |82 at the outer end thereof which extends up' wardly into the path of movement of a cam ele ment or flange |88 provided on the lower end of cam arm |58. .The cam element |88 comprises 65 a tapered portion |88' _which extends forwardly from the rear‘vertical edge of the arm |58 at an angle to the outer face of the arm and a straight portion |88" positioned at the forward side of the arm in parallel relation with the outer face thereof.

The fingers |80 of each set are each provided. with a bearing sleeve I8,3-._and these sleeves are >arranged in telescopic relation with -each other upon the stud |8| for maintaining the iingers positions, provide a passage through which the yarn guided by said fingers may pass beneath the clamping members. Yarn cut-o1? mechanism y Associated with each of clamping members 70 and guide fingers is a yarncut-off mechanism located adjacent the rear ends of the clamping ' members.4 This mechanism, as shown more par ticularly in Figures 6, 21 and 22, comprises a shear blade carrier arm |98 mounted in Va’slot 75 8. 2,137,362 |99 provided in the upper' face of the dial cam plate |35. 'I'his arm |98 is pivotally connected intermediate its ends to the dialï plate by a pin 200. To the end of the arm adjacent the corre sponding set of clamp members is secured a shear blade 20| which is positioned in close prox imity to a second shear blade 202 mounted in the slot |99 and secured to the 4adjacent portion _of the dial cam plate as by screws 208, Figure 22. 10 ’I'he edge of the shear blade 202 adjacent the clamps |80 is provided with an upwardly facing cutting edge 202', while the lower edge of the shear blade 20| is provided with a downwardly facing cutting edge 20|' adapted to cooperate 15 with the cutting edge 202' for severing the yarn. The blade 20| is normally maintained in its low ermost position by a spring 205 secured by screws 206 to the upper face of the dial cam plate |35 adjacent the inner end of the arm |98. The 20 forward end of arm |98 and the shear blades car -ried thereby are raised against the action of spring 205 by means of an operating plate 201 which, as shown, in Figures 2 and 6, is provided with a central opening for receiving the bearing sleeve |32 therethrough and is rotatably mount ed upon the dial cam plate |35. , The operating plate 201 is provided with a lat eraly projecting arm 208 at one side thereof to which is connected a push rod 209 which extends 30 rearwardly from the arm 208 and is operatively secured to the upper end thereof a stop arm 2|9 which, as illustrated more clearly in Figure 5, is adapted to be engaged by a detent or pawl 220 pivotally secured as at 22| to the gear case. lThe detent 220 is connected to one end of a push rod 222, which has the other end thereof plvotally connected as at 223, Figure 3, to one arm |55' of the bell crank lever |55 which is operatively connected with the cam arm |58 for operat ing one of the dial stitch cams |44. A spring 10 224 connected with the bracket |86 and rod 222 normally urges the detent away from the stop arm 2|8 to the position illustrated by broken lines in Figure 5, while the detent is positively moved into the path of movement of the stop arm 15 2|! by the action of cam |50 for maintaining the shaft and the mechanism connected thereto against rotary movement during the rotation of the shaft |3| and needle cylinder 48. The lower end of shaft 2|8 extends a short distance below the lower end of shaft ISI and has ñxedly secured thereto a bearing disk 225 which is of less diameter than the interior of the adjacent portion of the needle cylinder 48. 'I'he bearing disk 225 carries a plurality of, in 25 this instance l0, feeding. disks 226, each of which is secured to one end of a respective spindle 221 journaled in disk 225. Each of the spindles 221 extends inwardly from the peripheral edge of the bearing plate at a downwardly inclined angle 30 connected with a rock arm |55 mounted upon relative to the axis of the shaft 2|8 and also the shaft |56 which is adapted to be actuated in tangential relation to said shaft, as illustrated ~ through the medium of a push bar |52 by either in Figures 2 and 23. The peripheral edge of each one of two cams 2|0 mounted upon the pattern. feed disk 226 is corrugated or ,provided with a series of teeth 228 adapted to engage the fabric 35 drum 20. The operating plate 201 is also pro formed by the cylinder and dial needles as said vided with a pair of laterally projecting diametri fabric passes downwardly through the interior cally disposed members 2| | which normally ex tend outwardly at the rear of the respective blade of the needle cylinder. The`upper end ofthe i'n terior of the needle cylinder is beveled outwardly carrying arm |98 and when the plate 201 is ro tated by the action of a cam 2|0 in a clockwise as at 230, Figures 2 and '23, and is preferably 40 direction as viewed in Flgure`6, these projections provided with a ring member 23| composed of engage a cam surface 2|2 provided at the rear end of each arm |98 for pressing said end of the arm downwardly and raising the opposite end of the arm and the shear blade carried thereby. 'I'he operating plate is yieldlngly maintained in steel and which is seated in a suitable recess pro vided in the tapered portion of the needle cyl- A inder. 'I'he interior surface of the ring 23| is tapered so as to cooperate with said tapered por, 45 tion 230 to form a smooth continuous surface the inoperative position by a spring as |56 when ' throughout the axial length of said .tapered por the pattern _drum cams 2|0 are out of engage tion. t ment with the corresponding push bar |52. It will be noted by referring to Figure 6 that the shear operating plate 201 is provided with a pair ' of diametrically disposed apertures 2|5 through which the studs |46 extend, said apertures being of sufficient size and contour to readily permit the necessary ’swinging movement of the plate relative to the studs to effectthe operation of the shear blade carryingl arms |98. ` Each ofthe shear blade4 carrying arms |98 ,is also provided with an upwardly extending bore 24|8 adjacent the forward end thereof. In'v the bore 2 |3 is mounted a spring pressed plunger 2 I4which is adapted to engage the rear end of the uppermost clamping blade |90 and press Vthe same and the remaining clamping blades into> engagement with each other and with the disk |93 for clamping the yarn Y therebetween, as shown in Figure 22. Fabric feed mechanism The tangential relation of the spindles 221 to the axis of the supporting shaft 2|8 is such that 50 the peripheral portion of each disk 226, lying in the horizontal axial plane of the spindle and p0 sitioned at the rear side of the spindle, will be spaced a greater distance from said shaft axis than the diametrically opposite side of the disk. 55 It will thus be seen that the axis of rotation of each feed disk 226 is arranged both at an oblique angle with and tangentially to the axisy of rota tion of the'cylinder and dial needles and. there fore, to the axis o_f movement of the knitted fab 60 ric. It therefore follows that the rear peripheral edge portion of each feed disk which is‘located between the horizontal plane of the axis of ro tation of the disk and the extreme lowe'r side thereof will lie nearest to the fabric and, there 65 fore, will be engaged by said fabric as the fabric is rotated in an anti-clockwise direction as indi cated by arrow X in Figurel 23. As the fabric thus engages each disk, said disk will be rotated 70 As hereinbefore stated, the dial plate operating , in an anti-clockwise direction by the fabric so 70 that the fabric engaged by the peripheral edge shaft |3| is a tubular member and it has jour naled therein a supporting shaft 2|8 as shown in of the disk will be carried axially downwardly by the disk as said disk is rotated. It will thus Figure 2. This shaft 2| 8 extends upwardly be yond the upper end of the shaft |3| and through be seen that the rotation of the, fabric pro 75 a suitable aperture in the >gear case |05 and has duced by the needles actuates the feeding device 75 9,137,362 , - ' 9 n for automatically effecting the axial movement vcured. thereto to a sufficient distance above the needle cylinder to permit the ready positioning of of the fabric in a direction away from the ad jacent cooperating ends of the nedles. It will ' also be understood that the speed at which the- a transfer ring as R, Figure 26, having the par- , feed disks feed the, fabric axially depends upon the diameter of the~ disk and also upon the angu lar relation thereof with the axis of movement of tially knitted article mounted thereon over thecylinder needles 52 and transfer jacks 53 asso ciated with the needle cylinder 48. To explain more explicitly, by referring to the fabric, Figure 26, wherein the vertical lines represent - A stop pin 233 secured to head |06 is adapted 10 to be engaged by arms |55 for limiting the piv otal movement thereof produced by springs |66 when head |03 is in the raised position. In the modified form of feed mechanism illus trated in Figures 29 and 30, the shaft 2| 8 has secured to the lower end thereof in any suitable manner, a hub 235 which has secured to the upper face thereof a spring member 236 which is provided with a plurality oi' arms 231, one for each spindle 221. These arms 231- are arranged tangentially to the shaft 2|0 in the same man ner in which the spindles 221 are arranged in the structure shown in Figure 23. 'I'he outer end of each arm 231 is secured tothe outer end por tion of a ' corresponding bearing member 233 which, as shown in Figure 30, extends inwardly toward the shaft 2 I 3 in tangential relation there to beneath the corresponding arm 231 for rotat ably supporting the shaft 221 of a respective feed disk 226. It will be understood that there are as many bearing members 238 as there are arms 231` and disks 226 and, as illustrated in Figure 30, .these bearing members extend downwardly from the outer ends thereof at an angle to the axis of the shaft 2|0 and have the inner ends thereof terminating in spaced relation to the'hub 236 and in close proximity to -a supporting plate 239 ' secured to the lower end of the hub'23lì.> Each shaft 221 extends inwardly a short distance be yond the inner end of the corresponding bearing member 233 and has secured thereto a collar or bearing element 240. _ 4 It will now be understood that the feed disks 226 when mounted as shown in Figures 29 and 30, function in the same manner as when mount ed in the manner shown in Figures 2 and 23 for `taking up the fabric during the knitting oper ation. However, in the modified form, the feed disks have vertical movement-independently of each other due to the resiliency of the arms 231 which enable each disk to pass over knots or other unusual deformities or obstructions inci dent to the forming of the fabric. In‘operation, when a drive disk 226 is -thus elevated, it will be observed that the corresponding bearing mem ber will pivot about the -lower end thereof where said end engages the plate 239 as an axis against the action of the corresponding arm 231. t ’ corresponding teeth of ratchet wheel I5, as tooth ’ T-l of said wheel is engaged `and brought for 10 ward by pawl i4. the high point of cam |2| which produces sufficient rocking movement of latch ||3 to release head |06 -ls moved out of engage ment with the corresponding push bars, so that upon themachine’s coming to the at rest posi 15 tion, head |06 will be in the raised position while> latch' l I3 will be in the raised vertical posi tion with the head of the latch in the path of movement of latch plate lltì.A Also, cylinder cast-off and stitch cams 58 and 59 will have been 20 moved by the action of springs 19 upon rack members 69 to their inoperative positions out ofV engagement with the butts of the cylinder needles, as shown in Figure 25. It will also be noted by referring to Figure 26, thatcam 93 for 25 operating the jack ring'09 is so related to the latch cam |2| that prior to the engagement of the latch cam with the corresponding push bar, said `lack cam 93 will pass out of engagement with its push bar 94 and thereby release the rocker 30 arm 06 associated therewith and permit spring |0| ,to move push rod 90 forwardly and thereby effect the upward axial movement of the Jack ring and thus level the cylinder needles and transferjjacks in the manner hereinbefore de scribed and. as shown in Figure 25. ' It will now be readily understood that inas much as the cylinder needles and transfer jacks are maintainedat a uniform predetermined level. the stitches carried by the quills as 1' of transfer ring R. may be readily transferred to the needles and jacks engaged by said quills by merely pass ing the fabric F from a position above the ring. as indicated in Figure 27, downwardly through the ring and into the >interior of the needle cyl inder 48, as indicated in Figure 28, and in doing so, the stitches carried by the quills will readily pass downwardly therefrom onto the respective cylinder needles and transfer jacks. l The trans fer ring Ft is then removed from the needles and jacks and the dialplate and needles are brought into nearly cooperative relation with the cylinder needles and transfer jacks by the operator manu ally moving the dial supporting head |06 down wardly against the action-of the spring ||0 until 55 the latch ||3 again engages the latch plate H0.

As the .head |06 is thus released, spring ||0 will auto matically raise said head and the mechanism se plate ||6 and securely maintaining head `|06 and the dial Vneedles in their lowermost operative positions. Next, pawl i4 is caused to operatively engage tooth T--3 during which intermittent movement of drum 20 the forward reduced por tions. |10" and |1|" of the-dial‘cast-off cams |10 and |1| engage their respective push bars to effect' a partial upward movement thereof-and thus move the corresponding dial cast-oir cams 10 2,137,362 Ill to an intermediate position to produce sum cient outward movement of the dial needles |38 - to cause the forward ends thereof to pass through the eyes 53' of aligned transfer jacks 53 carried by the needle cylinder. 'I'he engagement of pawl I4 with tooth T-4 causes Jack cam 03 to next engage the corresponding push bar 94 and pro duce downward movement of jack ring 09 and thereby return the transfer jacks 53 and needle 10 jacks |00 to their normal inoperative position, thereby releasing the cylinder needles and at the same time transferring the stitches carried by the transfer jacks to the corresponding dial nee dies at a position -ahead of the needle latches. 15 The continued operation of the machine next brings the cylinderstitch cams 18 into engage ment with their respective push bars which op erate arms 12 to eifect the return of the cylinder cast-on cams il and cylinder stitch 'cams l! to 20 their operative positions relative to the cam track l1 and produce operation of the cylinder needles to eñect knitting. Simultaneously with the en~- drum 20 makes one complete revolution and as said drum approaches the end of a revolution the guide cam associated with the particular strand of yarn being used is arranged to engage the corresponding push bar and effect the return of the corresponding guide lingers |80 to the inop erative position to bring the yarn associated therewith out of cooperative relation with the dial and cylinder needles and at the same time cause said yarn to travel between the correspond 10 ing clamping members. As said yarn is thus engaged by the clamping members, a shear cam 2 I0 mounted upon drum 20 engages the push barl associated with the shear blades and effects the operation of said blades to sever the yarn being 15 used. Next, the cylinder stitch cams 1l, the dial cast oiI cams |10 and |1i, and the dial stitch cams |50 and IBI will be moved out of engagement with their respective push bars and thereby cause the 20 cam members associated therewith to be moved to their respective inoperative positions so that corresponding push bars, the high portions of the the cylinder needles positioned with the butts thereof in that portion of the cam track 51 adja dial cast-oi! cams |10 and |1| effect the return of the dial cast-oir cams to their full operative -position. while the dial stitch cams |50 and III cent the cast-off cams 58 and stitch cams 59 will be released by said cam members. Also, as the dial stitch cams i“ and cast-on cams |46 are effect a movement of the dial stitch cams I“ moved to their _innermost position with the outer ends of the dial needles maintained within the ~ gagement of the cylinder stitch cams with the to their innermost operative position so that the dial needles III will then function in connection with the cylinder needles for producing an article with a rib stitch. _ ' . It will be noted by referring to Figure 26 that just prior to the engagement of the cylinder stitch cams 10 with their respective push bars, one of peripheral edge of the~dial lplate |36, upon the next intermittent movement of the pattern drum, the Ajack cam 0I moves out of engagement with the push bar associated therewith so ‘that the jack ring is moved to its uppermost position for leveling the Jacks and cylinder needles and at the the yarn guide finger cams as |80 moves out of same time latch cam I 2| engages the push bar engagement with its corresponding push bar and thereby releases the corresponding rock arm |55 and permits the spring .|55 to move the guide lingers |80 associated therewith to their outer most operative position for bringing the yarn Y carried thereby into operative relation with the dial and cylinder needles. connected therewith for eilectinga limited move In case it is desired to shift from one yarn to another of a diiferent color after a predeter mined portion of the fabric has been knitted by the yarn nrst used, the yarn guide cam |80 may be so constructed as to again engage the push bar associated therewith and another yarn guide cam as |00 be terminated so as to release its corresponding push bar and thereby eiIect the return of the ilrst pair oi guide fingers |00 from the operative to the inoperative position and cause a second pair of guide ilngers |80 associated with the respective cam |00 to move to the opera tive position. At about the same time the second guide fingers are moved to the operative position. a shear cam 2I0 mounted on drum 20 e the push bar associated'with the shear blades and severs the first yarn úsed after a fresh por tion of the yarn has been drawn by the knitting needles between the corresponding clamping blades |80 so that the end of the severed yarn will be held thereby in position to be again moved to the outer operative position relative to the dial and cylinder needles by the outward move ment of the guide fingers associated therewith.

The next intermittent movement of the pattern drum causes the high point of cam | 2| to effect the momentary engagement of the trigger ill with the pin I I9 to release the head |00 and per 45 mit said head to be moved by spring ||0 to the uppermost inoperative position. The machine may be then stopped by any suitable automatic mechanism associated with the source of power or the drive means for said machine may be manually controlled to eifect the stopping thereof.
