PP" P are details in plan with parts .5 is provided, which In the patent to Robert H. Lawson, No. 1,605,896, dated November 2, 1926, there is disclosed means for effecting reverse plating through the action of special instrumentalities associated with the web holders and with'the needles, together with means for shiftin or altering during the knitting operation t e point or points at which reverse plating is effected, 1 By such means various patterns can be produced and among other patterns there may be produced inclined lines of reverse lating, all extending in the same direction a ong parallel lines or so arran ed as to cross each other, thereby producing 'amond or like effects. It is the purpose ofthe present invention to improve upon the mechanisin disclosed in the said patent, and par ticularly to provide means whereby the pattern means may be readily and quickly altered or rearranged.

In this application, as in the said Lawson patent, there is provided a series of special instrumentalities, one for each needle, and each such instrumentality is controlled or subject to control by pattern mechanism, so 15. that according to the dictates of the pattern mechanism, reverse plating may be effected at any needle, and there may be a change, by

progression, recession or otherwise in the pomt or area where the reverse plating is so effected. In the practice of this invention, a series of independent needles is provided desirably in a circular knitting machine. A needle cylinder 1, of the Banner or Hemphill type, as is herein shown provided with needles 2, which are represented aslatch needles, but which, when desired, ma be of any other suitable independent nee e type. In the web holder bed ring 3 there are provided the 00v usual grooves, in each of whic is inserted for in and out or radial movement a-web holder 4 desirably of usual type. Desirably in each such groove a special instrumentality shown in ,the said Lawson patent. The said instrumentalities 5, being placed side by side in the grooves with the web holders are capable of slidin longitudinally with .respect to the webi may be of the form as oldera. Said 'insti'ume'n- 10! I v 1 otherwise than to i the usual narrowing talities 5 do not function as web holders, be

they are rovided' with butts 6 that are ada tedto controlled by circumferentia'lly positioned cams radiall outside of the cam 15. m the sinker cam ringt at controlsthe butts 7 of the web holders 4.

The needles here shown being of? the latch needle, type, a latch, ring 3 is employed equippe with suitable binder mechanism generally indicated at,9 and controlled by link and lever mechanism. generally indicated at 10 and which need notbe'further described state that the same iscontrolled from thef ipattern drum. The entire mechanism is'idriven from the main drive shaft llhaving'thereon the usual pulleys and also suitable aring including the pinion 12 for driving't is large gear art as the 104?? gear) which is mounted u 11 the shaft 14. Erom said main drive 'sha is also driven in usual manner a quadrant 15 pivoted at 16, whereby the machine is reciprocated durin the'knitting of the heel and too. The mec anismis also provided with ickers, one ofwhich is indicated at 17, an the usual widening ickersoone of which is indicated at 18 in ig. Thesepickers are desirably those of the said Banner machine and reouireno further description. The needle cylinder 1 is rovided with the usual needle grooves receiving the needles 2, and, as already stated the usual web holder .with radial grooves receiving not only the" web holders or so-cjalled sinkers 4, but also the s ecial instrumentalities 5, said elements 4 an 5 being wholly disconnected from each other and capable of independent radial movement in said grooves, and are reci rocated therein by the cams, referred to, w ch are the same as those shown in said Lawson patent. That is to sav, an inner circumferentially extending cam is provided to act upon the butts radially cams, and radially outsi e of said two cams is provided a third'cam, all to act upon the butts 6 of the special instrumentalities 5, so as in the relative rotation or movement of 52 the needle cylinder and cam ring to move the said web holders and special instrumentalities in and out. i Pattern means of the general t 5 in said Lawson patent are rovide proved as hereinafter set orthto move the \s ial instrumentalities 5 and herein ush t em radially inward so as to bring \within the control of the proper cam of the sinker cam-ring. en the s ecial instru- ".mentalities 5 are moved inwar by the cams v of thesinker cam ring, they so enga e the proper yarn of the two yarns being normal plating relation as to reverse the plating, but if'not so moved radially inward. then normal-plating continuesor 1s efiecte shown 13 (known in the fast for rotatin movement upon spindl bed ring 3 is provide 7 of the web holders 4, and' outside thereof aretprovided two but imt em" r centers of the said disks, but are edm ' the said grooves at the needles pertaining to such special instrumentalities.

The pattern means is of such type as will rmit every needle to have reverse plating efiec 'l thereon. Desirably there is employed a part or arts rotating with the retating part of t e knitting organization.

Assumin' for purposes of description mere- 1y that t e needle cylinder is to be rotated, it is evident that t a rotating part might mesh with the needles so that in the movemen of the mechanism the proper relation may be preserved[ It is preferable, however, to provide cam ring or the needle cylinder, and herein are re resented teeth 19 upon the sinker cam ring see Fi '4 the same.- eshing therewith there is desirably provided two

gears

20, 21 respectively es 22, 23 received in

ariugs

24, 25 formed with or carried upon

brackets

26, 26 mounted upon the bed plate of the machine.

er height-than are the teeth 19 with which they mesh, sinceprovision is made for removinglthe pattern disks-out of engagement 'th some at least of the butts of the special instrumentalities 5 without disen aging the

gears

20, 21 from the teeth 19. T number .ofqteeth 19 for best results is equal to that alignment with each other and slightly for ex- =spaced apart;

In the said Lawson patent the pattern disks are provided with fixed, though adjustextendmg entirely about The teeth ofthe said

gears

20, 21 are desirably of greatother fixed As shown most clearly in Fig. l

able, members therein indicated at 46, 47 to engage the butts of predetermined special instrumentalities and move the same radially inward. Instead of employing such fixed members, there are provided

tern disks

32, 33 with

grooves

34, 35, in the upper face of'an outer annular portion of the said disks, as most clearlyshown in Fig. 6, for the ready reception and ready removal therefrom of a series of jacks. The said grooves are not radial with respect to the inclined at a considerable angle thereto for a purpose which will presently clearly appear. Within the said grooves or such ofi'them' asare required for the production of the particular pattern that is to be produced, there are inserted jacks 36 which do not reciprocate in but areheld in position the two pattherein by the overlying rings or annuli 37 38 therefor, as shown in section in Fig. 9 an in lan in Fig. 2. :The said jacks 36 are of the orm shown in Fig. 9a, being. provided with an upstanding portion 39 taking between the rin or

annulus

37 or 38, as the case may be, am? an inner disk or cap piece 40 shown 1n Fig. 9, secured in position by screws 41, one of which is shown in Fi 9, said screws 41 extending into the web 0 the disk like ortion that receives the said jacks 36. aid jacks 36 also have upstanding portions 42, 43, which are received within grooves formed in the under face of the ring or annulus 37 38, so as to hold the said jacks 36 from all lateral movement, said jacks bein held from endwise movement by reason of t e fact that their projections 39 are received between the ring or

annulus

37, 38, and the disk or cap 40. The grooves in the under face of the ring or

annulus

37, 38 are of course inclined to a radius to correspond to the inclination of the

grooves

34, 35. Z The rings or

annuli

37, 38 are held in fixed position in any suitable manner but desirably so as to permit them quickl tobe removed when the pattern is to be c anged, thereby permittin access to the jacks 36 and permitting a di erent distribution of the jacks or the employment of a different number thereof. For the purpose of holding the rings or annuli 37 38 fixedly but removably in position, there are here provided for each disk four

springs

44, 45 respectively, held in position by

screws

46, 47 respectively, the said springs extending at their outer or free ends over the rings or

annuli

37, 38, thereby holding them firmly but removably position. To remove the rings or

annuli

37, 38, it is merely necessary to remove one each of the pairs of

screws

46, 47 and then to swin the outer ends of the

springs

44, 45 inwar y to clear the rings or annuli 38.

The'outer ends of the jacks 36 are rovided with heads or bent ends 36 whic as shown in Fig. 9a are not of the entire height of the outer ends of the jack. The said heads

pattern disks

32, 33 are represented as engaging the proper butts 6 of the special instrumentalities 5 so as to push them radially inward for the purpose of efiecting reverse plating. It is not necessary to state herein how the special instrumentalities 5 act upon one of the two yarns, namely, the back yarn, so as to push or move the same into a position where it becomes the face yarn, since that action is very fully described in the said Lawson patent.

The construction described, namely, the utilization of removable jacks in the grooved pattern disks instead of fixed, thou h. adustable, projections as" in the said awson patent, permits a very ,quick change in pattern to be made, as obviously any distribution whatsoever of acks may be provided. That is to say, there may be a maximum number of jacks filling all the grooves of the pattern disk or disks in which case reverse plating would occur upon all the needles, and any lessbr number of jacks may be employed, and they may be positioned singly or arranged in groups according to the desired pattern.

The number of

teeth

20, 21 upon the spindles of the

disks

32, 33 is determined in the same manner as in the said Lawson patent. That is to say, if a single disk only were provided, as, for example, in producing I stripes all extending in the same direction, if the number of teeth on the disk were equal to or divisible into the number of teeth on the singer cam ring or other toothed driving part, the stripes or reverse plating would extend parallel to'the wales of the fabric. If the number of teeth on such single disk be not equal to or divisible into the number of teeth on the driving part, the plating stripes will be sloping, that is, they will cross wales.

. If two disks be employed, as here shown, and

the number of teeth thereon differs with respect to each other, and the number of teeth on either disk is the same as or divisible into the number of teeth on the driving part, then or bent ends 36' are bent at slightly more-adifierent effects are secured. If, for example,

than a right angle, being so beat that when a complete or accurate circle. Otherwise stated, the said ends or heads 36 are bent on an arcfrom the center of the pattern disk, this being for the purpose of permitting them to act accuratel each upon its own predetermined butt 6 o a special instrumental ity 5. It is, of course, of the utmost importance that each jack 36 shall engage the special instrumentality intended and not also engage the one next thereto, but shall clear the same. It is for this purpose that the said jacks 36 are placed in grooves which are at an angle to a radius from the center of the pattern disk. The effect of the construction provided is very clearly illustrated in the number of teeth 20 for the disk 32 be 119 and the number of teeth'21 for the disk 33 be 121, the constant rotation of the disk 32 results what may be termed an incremental gain and the constant rotation of the disk 33 results in what may be termedan incremental loss in the position of the reverse plating stripes produced or controlled therey. That is to say, certain of the stripes of the stocking or ot er fabric represent a constant incremental loss and the other stripes represent a constantincremental gain as to the needles upon which such reverse plating is effected.

An important purpose in having a conhave long butts and the remainder short stant mesh or driving relation between the gears for the pattern" disks and the rotating element is that if a stockin be knitted, it is desirable to provide for t rowing the reverse platin mechanism out of operation during the formation ,of the heel and toe. If the

pattern disks

32, 33 were removed from functioning relation without retaining the meshing relation of the teeth, the parts could not readily be restored to action without impairing the pattern. Improved means are provided for moving the pattern disks out of functioning relation for the heel and the toe. As in the Lawson patent, substan tially one half the special instrumentalities butts, corresponding in position respectively with the long and short butt needles. The

cal points. One of said notches or recesses of each of said collars is indicated at 50, 51

r 'in Fi 4 and the opposed notches are of similar s ape. Each such notch or recess is stepped atits bottom as clearly indicated at 52, 53, 54, 55, such formations being connected by an inclineoi'sloping portion 56, 57, and beyond the

surfaces

53, 54 are the second slo ing portions 56', 57 Just above each col ar 48, 49 are positioned upon the

spindles

22, 23 for turning movement relative to said spindles respectively two collars or rings 58,

a 59, each having three

projections

60, 61 extending into each of said recesses 50, 51, the op sed recesses being provided to prevent twisting of the parts. Means are provided to, impart a slight turning movement in two steps to the collars or rings 58, 59 so that as the

several projections

60, 61 ride up the slopes 56, 57, then onto the surfaces'53, 54, then up the slopes 56', 57 onto the u per surfaces of the collars 48, 49, the

dis

32, 33 are correspondingly elevated so as-to move the jacks out of engagement with the butts of the special inst'rumentalities 5, but without removing the

gears

20, 21 from meshing relation with the teeth19. At the lower ends of the

hubs

29, 31 are provided ball bearing cages 62, 63, so that the said

disks

32, 33 may urn freely or readily through the action of the

gears

19, 20, 21.

Springs

64, 65 connected to the said

collars

58, 59 and also to some fixed part of the machine are employed to return the said collars to the position shown in Fig. 4.

' In order to impart turning movement the said collars or rings 58, 59, there are .pro-

' vided upon the. attern disk 66 two pairs'of' I cams 67, 68, 69, 0, and back of the same two other 1 as t ey are concealed by the parts. Said pairs of similar cams not shown in Fig.

cams in the rotation of the said pattern disk the cams referred to as behind the same, and" thecollars or rings 58, 59.

At 71 there are pivoted the lever72 for opcrating the binder andthe lever 73, the latter having an arm 74, which is connected through means tobe described to the pattern disk 32, said lever 73 having a nose which rides u on the two pairsof cams similar to butbac of the cams67, 68, 69, 70. In order to hft the pattern disk 33 through the action of the

cams

67, 68, 69, 70, there is provided an upright rod 75, which upon one face there- 1 o so as to be acted u n by said

cams

67, 68, 69, 70, is provide a roll 76 shown in dotted lines inFig. 1. The said rod 'extends downward past the axis of the pattern disk 66 and is there longitudinally slotted as shown at77 for the reception of a pin or screw 78 constituting guiding means, said pm 78 being desirably supported upon a crow strip 79- secured to the face of the pattern disk 66 by screws 80. The said rod 75 at its upperend is nnected as shown in Fig. 3 at 81 to a hell or lever 82 ivoted at 83 upon a small bracket 84. Said ll crank lever 82 is pivotally connected at 85 to a link 86 which lifting the pattern disk 33.

"

Thelever

73, 74 which rides upon similar cams (not shown) is pivotally connected at 88 to avertically extending rod 89, which is connected at its upper end, as shown in Fig.

106 is connected at 87 to the ring or collar 59 for 5, to a bell crank lever 90 that at 91 is iv- I otally connected to a transversely exten ing 1 link 92, the other end whereof is pivotally connected at 93 to the ring or collar 58 for lifting the pattern disk 32.

The cams67, 68 and the similar cams back of the same, are employed for moving the two'

pattern disks

32, 33 out ofoperation for the heel, and'the cams 69, 70 and the two came back thereof are employed for moving the said

pattern disks

32, 33 out of operation for the toe. The said cams 67 68, 69,70 act with the bell crank levers 82, 90-tolift the

pattern disks

33, 32. Forboth heel and toe work said pattern disks are lifted until the projections 60 rest upon the highest of .thethree levels of the collars 48, 49 (that is, on the upper surfaces of said collars). The springs 64,

made to said patent for full explanation, but

as the means employed for this purpose is desirably the same as shown in said atent, it is unnecessary to refer thereto. a operating rod therefor is indicated at 93' m ft has been discovered that during the formation of the heel and toe, there is sometimes a tendency of the special instrumentalities 5 (operating as they do in the same grooves as the web holders 4) to bind and cut the yarn, especiall after the needles in action in the heel an toe are elevated by the instep cam. In order to overcome this tendency, the means shown in Figs. 10, 11 and 12 are provided.

In Fig. 10 the instep cam is indicated at 94 and the series of needles is represented at 95 as elevated thereby. As these needles are thus elevated, and articularly the end needles of such series, t e yarn is so tighty gripped about the end needle of the series that as such needle and succeeding needles are elevated the am is also correspondingly lifted instead of the needle or needles sliding through the loop or loops of the yarn. This brings the yarn as represented at 96 in Fig. 11 into such position that it is liable to be cut by the inner edge of the special instrumentality 5 in the same groove with the web holder 4 in question.

In order properly to position the yarn and to prevent such cutting and bindin a pair of special, fixed, two-part cams, s own at 97, 98 in Fig. 10, are provided. In either direction of reciprocation the needles in action ride up the slope of the cam 97 as indicated at the right in Fig. 10, so as to raise the said needles substantially one eighth of an inch. immediately thereafter the same needles are lowered substantially one sixteenth of an inch by the slope of the cam 98, and the result is to bring the yarn 96 into the osition shown in Fig. 12 at the bottomv o the throat 99 of the web holder 5 in question instead of at the top thereof. Thus, the yarn 96 is in Fig. 12 brought into such position that it is not bound and severed by the special instrumentality 5, as might be the case if the said yarn 96 remained at the upper wall of the throat 99 as in Fig. 11.

While the jacks 36 are shown and described as moving special instrumentalities 5 so as to result in reversing the position of the back and face yarns, it is to be understood that the said jacks or equivalent means may be employed to operate upon parts other than specialinstrumentalities 5 in effecting change member supports from normal plating therefore it is desired to cover the same broadly. For example the said jacks might be employed to give suitable in or out movement or both to certain needles instead of to special instrumentalities 5, and thus result in reversing the position of the back yarn and face yarn, thereby securing reverse platmg. I
