This invention relates to making split tubular fabrics on-automatic knitting machines stockings in separate succession. of the kind having provision for beginning To the above ends, it willbe observed that the knitting of each of a separate succession in machines of the kind having devices for of relatively complete stockings on the bare makin needles; for automatically knitting and fasit. is esirable to provide a series'of intening down a welt of the inturned-kind; for struments operating within and behind the knitting a stitch-length fashioned leg and needles adapted to receive and detain a course ankle by single-course circular knitting; and of the fabric, or bights in a course ofthe for completing the stocking by knitting an fabric in such a way as to allow the producankle, foot, heel and toe portions, provided tion of fabric for the welt; these devices must if desired with sectional spliced reinforcebe such as to operate thereafter to transfer ments above the heel'at the back of the ankle, their Withheld bights onto the needles for at the heel, along the sole of the foot and knitting the remainder of the stocking. It at the toe. An object of the invention is to is therefore necessary to so provide new means in combination with the foot or split-leg kmttin devices as not to existing agencies of a machine of the kind disturb the devices for ta ing and withholdmentioned so as to enable the machine autoing the bights and not to disturb the devices cooperating with needles throughout the series of needles to cause them to receive the bights from the bight-withholding devices.

In order to knit a split and suturedtubular structure'by reversed part courses, devices for simultaneously forming and knitting at knitting waves respectively formed in complementary series of a circle of needles are obviously necessary if the formation of bothof the split portions of the tubular knit fabric is to proceed simultaneously, and as a corollary to this, it is desirable to equip a knitting machine for knitting such tubular matically to produce relatively complete a stocking simultaneously by reversed partial by a suture between selvages of respective parts of the fabrics for the top of the foot if desired, to knit the section at the back and above the heel of the and the corresponding segment of the ankle of the stocking, by reversed partial courses interlocked at lateral sutures extendfabric. v

One object of this invention. is to provide means for effecting split foot knitting in machines of the kind indicated which shall, so far as possible, utilize the existing agencies of automatic machines for knitting stockings ofa type not capable of knitting split and sutured structures. Another object of the in- In machines of toes by reciprocal motions through something more than 180 of the needle circle of the main cams and yarn feed guide, and for the operation of narrowing and widening devices, so as to knit first a narrowed gore and then a widened gore on a segment of the needles for a heel or toe pocket, during suspension of knittingpn the needles of the remainder of the circle ofneedles, In order to rovide for split-foot knitting, it is desira le that the devicesfor and the operation the split tubular mode of knitting. the op-. erating means being of a character adapted to be placed on machines already containing the complex devices necessary for the other uses the existing devices. to make split tubular knitting and to avoidinterferingwiththe function of the existing devices for starting on the bare needles, making w'elts, knitting heels and toes, and in general operating auto and fastening-oil an inturned welt,

provide the splitthe kind above mentioned devices are provided for knitting heels and structures with devices for forming, feeding of forming heels and toes in this familiar way shall not be disturbed, and one object of the present invention is toprovide devices for the particular function of split tubular knitting which shall in part utilize the heel and toe knitting devices and which shall not disturb their operative function for their usual purposes.

In order to knit split tubular knitting by relative reciprocal motions between the needles and web-holder devices and their operating cams and yarn-feeding means, it is moreover desirable to utilize the existing devices for causing reciprocator motion between the needles and their we -holders and the other operating parts. But for heel and toe knitting automatically, these reciprocatory motions are confined to a time and aduration corres nding only to the production of heel an toe fabric, whereas for the present purposes reciprocatory motion should be in in a predetermined relation to the point or heel or toe knitting, and precede or follow heel or toe knitting for the production of so much of the tubular fabric as is desired to be of split sutured formation: and therefore the machine should be provided with devices for change from rotation to re ciprocation amenable to these uses; one object of this invention is to provide for so operating the existing reci rocating mechanical movement as to secure t ese results.

Since split-foot tubular knitting requires two knitting waves, provision is made according to this invention for feeding a knitting yarn for the second or auxiliary wave, and one of the objects of this invention is to provide devices consistent with the presence and operation of the welting and other stocking knitting devices for automatically initiating the feed of a suitable yarn to the auxiliary wave, for withdrawing this yarn at the cessation of split tubular knitting, and for severing and holding it until it is again required to be fed.

The invention will now be explained in respect to a s ecific instance in which the automatic startlng, welting, leg and heel and toe fashioning, driving and pattern mechanism and yarn feeding devices correspond to the well-known Scott & Williams machines, built, for example according to the Letters Patent of Robert W. Scott, No. 1,282,958, dated October 29, 1918 and No. 1,256,062, dated February 12, 1918. In the accompanying drawings,

Fig. 25 is a diagram plan illustrating a typical arrangement of the series of needles.

Referring now to Fig. 1, the machine may comprise the usual frame 1 supporting the usual upper table or bed 2 for a knitting head comprising a needle cylinder 260 supported for rotation at the top of a hollow column 280, which may be utilized by lifting and lowering movements to lower or raise the needle cylinder for shorter or longer stitches.

The machine comprises the usual drive shaft 32 adapted to'be clutched to or disengaged from a driven gear, not shown, operated from the usual belt pulleys, or clutched to a gear 35 meshing with the rack sector 7 5 central on shaft and adapted to be oscillated by a pitman and crank operated from the drive pulleys.

The lateral position of Q30 a clutch shifter element 92,-

1,'on the the bevel gear ring integral with or attached to the needle cylinder'is driven to rotate, or to oscillate through an are measured by the arc of oscillation of the sector 75. Also as usual in the art, the clutch shifter 92 on shaft 32 is automatically operated by coaction with a cam track on a clutch drum 90 mounted fast on the shaft 80.- Motions of the shaft are the effect of advances through greater or lesser parts of the forward stroke of .a pawl 82 on an eccentric stud 77of and oscillating with the sector 75, and having an effective stroke in contact with an irregularly toothed racking wheel 81 fast on the shaft 80, as determined by a controller for pawl 82, not shown, rocking on the shaft 93, and positioned by lugs of different heights on the mutuable link pattern chain carried by a sprocket 84 fast to a ratchet 86 having a bear ing on shaft 80 and constantly moved forward during the operation of the machine by the pawl 87, also mounted on an eccentric pin on the sector 75. The effect of these pattern devices is, as usual, to-move the shaft 80 forward intermittently after a predetermined number of revolutions of the drive shaft 32, as determined by the position of lugs on the chain 85.

The operative agencies of the machine are controlled by cams either on the shaft 80 or on rotary bodies geared to and moving in unison therewith, except as they may "be otherwise moved. The shaft makes one revo-' lution during the progress of each complete cycle of the machine to knit a stocking or other article, and it is desirable to parcel out periods of angular advance of the shaft 80 with economy, in order to enable a sufiicient motion of the pattern mechanism to accom modate all of the shifts and changes to be made.

According to the present invention, the usual or base machine is provided to be operated reciprocally by clutching the shaft 32 to the pinion 35 during the operation of the machine to knit split tubular portions of the fabric, as well as during operation of the machine to knit heels and toes. But because it is necessary to make diflerent dis ositions of parts of the machine for split tu ularknitting and for heel and toe knitting, it is pro-. vided' by this invention to move the clutch shifting drum without shifting the clutch, for the purpose of initiating heel or toe knitting, ceasin heel or toe knitting, and resuming split tubular knitting. The changes for thls purpose over the machine of the Scott Patent No. 1,282,958 may comprise no more than providing inclines of the cam .track on the drum 90 at a sharper inclination than usual, and providing extra ratchet teeth 81a, 81b in the rack wheel 81 for the purpose of having fashioned plainfabric leg L, and an ankle permitting short motions of the rack wheel 81 and drum 90 between actuations of the drum 90'eflective to shift the clutch. These extra teeth 81a, 81b, shown'in Fig. 1, need not be provided at a position corresponding to the formation of the toe of the stocking, but a short efi'ective motion only of the rack wheel 81 by the pawl 82 may. instead be provided by causing pawl 82 to take a tooth of the wheel 81 onl towardthe 'end of its forward stroke to shi t the machine agencies to single course reciprocal knitting for the narrowed and widened toe pocket; shifts the shaft 80 to change from narrowing to widening; and shifts the clutch on shaft 32'to resume rotary knitting after making the toe. The pawl 82 may be controlled for this purpose as usual by the controller rocking worked by a lug on chain 85.

Referring now to Figs. 1, 2, 3 and 4, Fig. 5 and Figs. 15 to 17., and 25, the needle cylinder 260 may be provided with a usual series of needles 1?. having shorter operating butts than the usual complementary series of long butt needles N. These needles may be distributed in segments of substantially equal numbers, theneedles n being operated upon to make the heel, toe and sole of a stocking suclr as that shown at S in Fig. 23 and the needles N corresponding to the instep, front of the leg and top of the foot. In order to provide for knitting sutured fabric for the split tubular sections 2', h at the front of the ankle and back of the ankle, and f, s at the top of the foot and sole, the segment of needles 1:. may overlap the segment of nee- .dles N at each end, and vice versa, the suture needles n and n of the shorter butt set intervening between the suture needles N'- and N 2 and the remainder of the longer butt set.

If now reciprocal knitting is conducted on the needles respectively of each of these two series, a walc from the needles n" and a Wale from the needles N will be related to the remainder of the fabric in a suture between selvages as illustrated respectively-in thewales a and b in Fig. 24. The devices described below are preferably employed with needles so arranged. I

A typical product illustrated in Fig. 23 may be assumed to comprise a stocking be ginning'at a'course-wise selvage w, having a course containing transferred bi hts w; the inturned welt W, a stitch-length and foot portion conjoined by the suture a, b, illustrated in Fig. 24. The. sections b, above the heel, and s at the sole of this stocking may be knit of the same yarn or a different tyarn from leg L, or the same yarn reinforced y an additional yarn, and the narrowed and widened heel H and toe T may be knit of the same yarn as or different yarn from the sections k and s.

Also as illustrated in Fig. 23 the heel or on shaft 93, v

vof operation of the machine, split tubular knitting ends at the line 2 a, the machine resuming rotary motion to knit the sections 77, r, and resuming reciprocal motion to knit the toe pocket T. The usual loopers rounds, not shown, may be knit following the toe pocket T. Y v

To effect the several operations producing products typified by Fig. 23, the machine is provided, Figs. 2 and 15 to 17, with the usual cam cylinder 261 having the vusual knitting cams 6 and 7, the usual top center cam 8 and a bottom center cam 9. During rotary knitting the stitch cam 7 may be the leading stitch cam and the cam 6 the following cam, all of the needles passing above the cam 7 and beneath the cam 8 to knit at the cam 6, whereupon they are returned by the cam slope 5 to the tuck position illustrated by the level line of needle butts in Fig. 15. The construction, adjustments, and mode of operation of the cams 6, 7, 8 and 9 may be as usual in the art. Associated with the'cams 6 and 7

narrowin pickers

650, 650 may be constructed and a a ted to operate as usual. The cam groups 6, 7 8, 9 may, as usual, be positioned at the rear of. the machine under a series of yarn changing yarn guides .F to F adapted when operative to deliver their yarns from a throat F in the latch ring 550, and adapted when inoperative to withdraw their yarns upwardly and within the space defined by the needles. Withdrawn yarns are received above a dial cap d, as presently referred to. The yarn guides F to F comprise the main yarn feed, and the knitting cams 6, 7, 8 and 9 are concerned with the formation of the main knitting wave.

Referring to Figs. 2, 5, 16 and 17 ,,in order to make the suture a, b of Fig. 24, it is desirable 'not to tuck at the leading short butt needle n or M, which may result if the narrowing

pickers

650, 650 are left in operation whenever there are reciprocal motions between the cam and needle cylinders. Provision is therefore made for lifting the

pickers

650, 650 out of operative position, as shown in full lines in Figs. 16 and 17, except for knitting for heel and toe, by apattern operated Arcuate

horizontal levers

652, 652 pivoted between their ends on the main knitting cam support are provided to take under the

pickers

650, 650, respectivel at one end of each lever, the other ends over apping behind the center cams, and, see Fig.5, under the inner end of a lever 654 pivoted between its ends on bedplate 2, the outer end of lever 654 taking over a block 655 on the lateral face of one of the thrust-bars 460 worked by cams on pattern drum 120. This thrust-bar may be that adapted to lift the yarn finger F carrying the leg yarn, whichis usually exchanged for another yarn appro riate for the section it upon beginning to ma e split tubular fabric. The block 655 may be so placed as to require an egrtra high lift of its thrustbar to work the lever 654, and in that case, the pickers can be released to usual position without moving finger F' to feeding sition. For the purposes of the machine 0 the said Scott Patent No. 1,282,958, the machine also comprises devices for knitting a starting sel 'vage, devices for taking and detaining bi hts, and devices for operatm the needles an the devices for taking the bights to transfer the taken bights to the needles.

Referring to Figs. 1, 3,4,5, 7, 8 and 9, a dial bed d for the bight or loop taking and transfer implements is fast on the lower end of and driven by adial'shaft 3 concentric with cylinder 260 and held in a vertical bearing hub 14 of a bracket .14 mounted on the latch ring 550 by'a bevel gear 15 meshing with a inion 16 on a horizontal shaft 17 also in bearings of bracket 14. Shaft 17 is driven by a bevel gear 18 meshing, when the latch ring is operatively positioned, with a pinion 19 at the top of a vertical shaft 10 in an upright bearing bracket 11 mounted on bed plate 2, which is bored for shaft 10. At the lower end of shaft 10 a pinion 10 meshes, Fig. 3, with a bevel gear 31" formed on the needle cylinder driving bevel gear 31 fast on drive shaft 32. The dial d is thus driven in unison with the cylinder 260 whether the motion is rotary or reciprocating.

The dial cam cap 03 has, see Fig. 8, a bearing hole 11 in a central bore taking over the hub 14 and is held against rotation by a steady pin d Figs. 8 and 9, entering a hole in bracket 14. The dial cap receives withdrawn yarns on its upper surface.

Referring to Fig. 15, the needle cylinder 260 is provided with jacks 381 under alternate cylinder needles, and the cam cylinder 261 is provided with a groove 365 for the jack butts, which are advanced at a cam 366 to move alternate needles upwardly to pass above the leading stitch cam 7 and a radially movable dividing cam 382. When the cam 382 is operatively positioned, the needles not advanced by the Jacks 381 are retracted beneath the stitch cams and at the slope 5 pass up-.

wardly in front of the yarn, these beingchar- 4 acteristic operations leading to the formation of a starting selvage on bare needles by the operation of the .cam 382 and the jacks 381,

as fully described in said Scott Patent No.

Operating between the jack cam 366 and the cam 382, a movable depressing cam 12 is made use of to manipulate the needles for receiving bights of a transfer-course, and with this may be associated an advancing cam 13 for delimiting the taking or transferring of bights to a single course. The earns 12 and 13 cooperate with transfer bits operating in radial grooves d*,

, all according to said Patent 1,282,958. These devices being desirably employed in the making of stockings according to this invention, the'rem'aining devices are required to coop erate with them. The construction and mode of operation of the said devices is arranged to remain substantially as described in the said patent. r

According to the said Scott patents, the operation of the :cams' 382 12 and 13, the operation of theyarn feed guides F to F", and the operation of the devices requiring to be moved for the purposes of making the product in relation to the .dial cap (1' are all controlled by thrust bars 460 su ported in inclined positions-at the rear of ti? and resting upon the periphery of a cam drum 120 on the shaft driven by gearing 121 from a gear 122 fast on the shaft 80. At times the drum 120, shaft and its attachments may be driven forward during a particular se ment of angular -motion of the needle cylmder, through short angular distances, by the awl lever 431 reacting with cam 430 "on shaft 32 and engaging occasional ratchet teeth on drum 120 to operate at exact times special needle cams. This mechanism is retained substantially unchanged, as appears at 12, 20. 382, 487 in Figs. 2 and 3.

The cam cylinder 260 is provided with the usual web-holder bed 295 for the usual webholders 292 having butts adapted to be operated by a web-holder cam cap 300. So far as the coaction of the web-holders with the needles operating the/main cams 6 and 7 is concerned, the devices may be the same as those in said Scott patents.

For the purposes of this invention the machine is equipped with auxiliary knitting cams. preferably operating at a point 180 displaced from the knitting cams cooperating with the main knitting wave. Referring now to Figs. 2 and 4 particularly, there may be provided for the auxiliary cams, above the bed plate 2, a slide 100 radial in respect to the needle cylinder and cam cylinder and adapted to move toward and away from the center of rotation of the needle cylinder in a. way provided by hold-down

plates

101, 101 screwed to the bed plate 2 and occupying the space between symmetrically arranged brackets 102 and 103 providing a bearing respectively for widening

pickers

680, 681, their directing

cams

682, 682, and their

guard cams

683, 683. The standard 103 also carries above the space occupied by the slide 100 a vertical support 400 for the latch ring 550 andlatch 558 (Fig. 4).

The slide 100 is provided with a vertical stud 105 which takes into a hole in a lever e machine whic is ivoted to a link 108 pivoted to a bell cran leverf109, Fig. 1, pivoted on an auxiliary frame 110, Figs. 1 and 2, secured to the bed late .2 at the rear of the machine and over t e pattern drum 120.

The frame 110 provides a bearing housing for the transmissionof the indications of a series of thrust bars 465" operated by appropriate cams on the'drum 120, and serving to ad'ust' agencies of the machine concerned with the operation of the needles,

feeding the yarn, and determining webholder function at the auxiliar wave. For example, the thrust bar 466 gui ed in acomb 467 on stud 450 in a perforated plate 468 on the frame 110 reacts against 1 the elbow of the pivoted bell crank .109 move and hold, through .link 108, the lever 106and slide 100 against the stress of aspring 111 in its in- 'ward operative osition.

Referring to igs. 15 to 17, the slide 100 may comprise an arc-shaped plate 112 adjustably carrying the reciprocal stitch cams 113 and 114 and a top center cam 115. When the slide 100 is inwardly positioned these cams are radially positioned to engage and act upon the long butt needles N only. Preferably the arc-shaped carrier 112 is also provided with guard and advancing cams 116 and 117. The usual cam ledge of the cam cylinder 261 is cut away at 262 Figs. 2 and 15 to provide a free space for the motion of the cams carried by the slide 100 and the needles moved by them.

While the cams on the slide 100 and 112 may be relied upon to operate the long butt needles for reciprocal knittin upon them from a yarn fed in proper re ation to the knittingwave in the long butt needles, it is necessary to provide that the long butt needles shall not knit at the cams 6, 7, and 8, with which they normally cooperate for retary knitting, for example when making the leg or welt of the illustrative stocking. When it is desired to knit a heel or toe, it is provided that the long butt needles shall travel in their usual elevated position in relation" to the main cams 6 and 7, and for heel and toe knitting the short butt needles should cooperate with a widening picker or pickers. The usual place for the operation of a widening picker is occupied by the auxiliary cams 114, 113, but right and left widening

pickers

680, 681 may be positioned to take down the leading member of any series of needles reaching them on the far side, in the direction of travel, of the cams 113, 114, which are-withdrawn out of reach of needles during heel and toe knitting. It is therefore desirable to provide for the elevation of the long butt needles not only for heel and toe knitting for the usual i ling of an instep segment of the needles but, in a different sense, during their normal knitting activity 106 ivoted at 107 on thebracket 102' and when knitting split tubular fabrics, in order to enable these needles to pass the main cams without there knitting, and without disturbing the performance of the short butt needles to knit at the main cam.

This invention provides for these purposes deflecting cams A and 15, Figs. 2, 15, 16, 17 and 18, adapted to cooperate with the long butt needles only and means for automatically adjusting these deflecting cams to provide for snitching the long butt needles above the main stitch cam and into the auxiliary stitch cam during split tubular knitting; to position the long butt needles at their upper idle level for heel and toe knitting; and to reposition the longbutt needles for split tubular knitting after making a heel or toe.

Referring to Figs. 15, 16 and 17, it is preferred to place the deflecting cams A and B asymmetrically in respect to the main stitch cams, so that the leading and following cams A and B respectively in the direction for rotary knitting may respectively follow the auxiliary cam group and the main cam group at about the same distance. Preferably the deflecting cams A and B respectively are so constructed as to provide an inclined throat or passage for the long butt needles; for example as best shown in Fig. 18 each of these cams may comprise a channel I) having one side 6 long enough to react on any short butt needle 71 which may encounter it, and the other side too short to encounter short butts.

Referring to Figs. 2 and 3, the cam A may be integral with or attached to the inner end of a slide 113 held in a slide bracket 112 mounted on the bed plate 2. Slide 113 is provided with an enlarged head 114E taking against a compression spring 115 between it and face of the bracket 112 acting to withdraw the cam A from operative position. Pivoted at 116 on a lug of the slideway 112* a lever 116 is connected by a link 117 to an arm 118 on a rock shaft 119 having a bearing in the frame 110. Shaft 119 is provided with an arm 130 overlying a thrust bar 468 of the series 465, and is therefore adapted to be operated at times determined by an appropriate cam on drum 120.

Cam B is mounted on a slide 131 in a slideway bracket 132 mounted on the bed plate 2, and provided with a compression spring 133 taking against its enlarged head 134, against which a lever 135 pivoted at 135 on a lno; of slideway 133 may be thrust by a link 136 connected to an arm137 fast on a rock shaft 138 having bearings in frame 110. An arm 139 on shaft 138 overlies a thrust bar 469 of the series 465. This thrust bar is also operated by an appropriate cam on drum 120.

When cams A and B are moved into operative position, see Fig. 16, during rotation of the needle cylinder in the direction of the arrow 00, Fig. 15, the cam A operates as a switch or deflector cam to deliver the long butt needles N above the top center cam 8 of the main cam. Any needles N which may reach the cam B after passing the main cam are deflected back to their normal tuck position.

Any needles n which pass the cam B are not affected. 'lheneedles n pass across the face of the auxiliary cams 113, 114 whatever the relative direction of their motion and whatever the position of the slide 100 and sector 1.12.-

It is desirable to make no changes of degree in the extent of the oscillatory arc swept by the needle cylinder when the pinion 35 is clutched to the shaft 32. In the machine selected for illustration, the contact points between the ends of the segment of needle n and the segment of needles N, at which points the suture needles n, N, 92 N are placed, oscillate through an are somewhat less than a whole revolution and having its end point for the leading short butt needle a moving in the direction of the arrow 31 Fig. 16, at the cam B, the leading needle N then having reached the position of the cam A. In the opposite direction (motion in the direction of the arrow at, Fig. 15) the leading short butts at the end of a stroke may reach the cam B, or stop in the relation shown in Fig. 17 to the cam A. In either case, it will be observed that in respect to either of the set of needles n or the set of needles N, there has been a complete passage through the cams of the segment of needles intended to be operated by these cams. For example the short buttneedles n enter and pass completely through the cams 5, 6, 7, 8, 9, the last needles of this series resuming the normal tuck position after passage by the cams in each direction; and similarly the long butt needles N enter and pass completely through the auxiliary cam group 113, 114, 115, the last needle of this series, moving in whichever direction, entering the cam A or the cam B at the end of the stroke. It will therefore be plain that before" entry into operative position of the auxiliary cam, which entry occurs during passage of the short butts n, the leading needle on the next stroke of the long butt series is properly positioned at the tuck position to enter the auxiliary cam.

I This condition of position of the long butts is not however true whenever the machine. having been knit-ting split tubular fabric, resumes motion in the direction :1: for rotary knitting, the cam A being withdrawn outwardly. In that case some of the long butt needles may be left in the position shown at the cam A in Fig. 17 on the retirement of that cam, and these needles would not then certainly enter the main cams to knit.

This invention therefore provides a cam C adapted to be entered whenever rotary plain knitting is to follow split tubular knitting or split tubular knitting is to follow heel or toe knitting. The cam C is a depressing cam, and as best shown'in Figs. 2 and 3 may conveniently be mounted on slide 21 superposed on the slide bracket 21 carrying the actuating slide 12 for the cams 12 and 13, Figs. 15 to 17, which in the machine illustrated is operated by a horizontal lever worked by'a cam 462 on a thrust bar 462. To enable the slide 21 and cam C to be operatedby this same connection, slide 21 is provided with a headed stud 21 and compression spring 21, the stud taking through a hole in a lug 21 on the lever 20. These arrangements are such that the cam C is thrust in'whenever the lever 20 is moved; but the cams 12 and 13 are moved only when the amplitude of motion of the lever 20 is sufliciently great to bring its end in contact-with the slide 12. The thrust bar 462 may therefore be lifted by an appropriate cam on drum 120 to a lesser extent to move the cam G into 0 eration than to move the cams 12 and 13. s mentioned above the cams 12 and 13 are used during transfer of the uniting course for the welt 1V, and are not used during split tubular or heel or toe knitting. v

In the machine of the said Scott Patent No. 1,282,958 alternate needles of both series provided with jacks 381 are raised to position to clear the cam 382 at each revolution of the machine by the operation of the cam 366. In the present machine, if this were permitted to take place throughout the -opera-' tion, the short butt needles with jacks, which desirably should be left at the tuck position, would be left too high. It is therefore provided to move the jacks 381 to their full height only at times when the machine is not operating to make split tubular fabric. To this end the jack cam 366 may be cut away at its apex at 367 and provided with an auxiliary movable apex part 368 adapted to be moved to the full line position, Fig. 15, prior to beginning a new stocking. Preferably cam 368 is carried on a slide 369 in a vertical slideway cut in the outer thickness of the cam 366. Slide 369 may be lifted by a link 370 pivoted to it at 371, and in turn pivoted to a crank arm 372 on the inner end of a rock shaft 373, Figs. 2 and 3 in bearings onone side of the bracket 112, and provided with a crank head 374, normally rocked by a spring 374 to hold the auxiliary jack cam 368 in the position of Figs. 16 and 17. lVhen the auxiliary jack cam 368 is to be normally positioned as shown in Fig. 15,.shaft 373 is rocked by a lifting movement of the thrust rod 37 5 extending through bores in the bed plate of the machine to contact with a cam 82 fast on the gear 122 fast on the left end of shaft 80. see Figs. 1 and 19. The contact end of rod 375, Fig. 3, may carry a compression spring 375 to insure lifting part 368 to its full height.

Whenever an auxiliary wave is formed in depending flange 302 having a running fit on a shoulder of the web holder bed 295, and restrained from rotation with the web holder bed by the adjustment screws 303 in lugs 304 except for an angular fall back motion in consequence of these provisions through the gaps between the ends of screws 3.03 and the faces of the standard 400. I

p The underface, Fig. 12, of the cam cap is provided with the usual groove 305 concentric throughout the greater part of its periphery-but interrupted by a recess at the back of the machine for a fixed web-holder withdrawing cam 308, the groove 305- being provided with advancing shoulders 309. In order to provide for web-holder function at the auxiliary wave, the interior flange defining groove 305 of the cam cap is cut away at 310 to provide a space to receive a vertically movable '312 to enter upon them from above.

Cam 312 is mounted on depending headed pins 315 extending through bores in a guide plate 316. The central pin 315 may have a projection 317 adapted to take over a lever 318 pivoted at 319 on a lug 320 of plate 316. The cam 312 is urged downwardly by compression springs 321, Fig. 14, surrounding one or more of the pins 315. One end of lever 318 extends through a slot in an angle plate .322 erected on the upper surface of the cap 300 and having pivoted thereto a spring latch 323 engaging lever 318 and having an outwardly projecting tail 324. The end of the lever 318 projects tangentially, Fig. 11, be-

yond the right-hand lug 304. When the lever 318 has been lifted against the stress of springs 321 the cam 312 is upwardly out of reach of the butts of web-holders 292 and is latched in this position by the latch 323. The cam 312 is put into action by depressing the tail 324 of the latch 323, and is taken out of action by lifting the lever 318 by its projecting end.

The cam 312 is moved into and out of operation by a vertically movable slide rod 326, Fig. 4, having a head 327 from which pro jects a pin 328 taking under the lever 318 and adapted to lift said lever on an upstroke of the rod 326. The head 327 also carries a cam latch 329-adapted to pass the tail 324 of the nism. As shown, Fig. 4, the lever 330 pivoted to rod 326 and at 331 on the underside of the bed plate 2 normally depresses the slide rod 326 by the stress of a spring 332. A lever 333, Fig. 1, pivoted on a depending lug I 334 under the bed plate 2. at one end takes over a block 335 attached to the face of one of the thrust bars of series 465. A suitable cam on drum 120 therefore controls the vertical slide 326 to enter and withdraw the webholder cam 312. \Vhenever the auxiliary cam wave is established in the long butt needles N the cam 312 is previously entered to withdraw the web-holders at the downgoing phase of this wave. It will be observed that the connections 318 to pin 328 and 324 to latch 329 are such as to enable the lost motion oscillation of the web-holder cam cap 300 to take place without breaking the operating connection.

Whenever the auxiliary wave is established in the. long butt needles it is important that the leading needle shall be fed with a yarn appropriate to the front part of the fabric being knit; for example, in the illustrative stocking, a yarn similar to the leg yarn and suitable for the sections 71 and f. The devices relied upon for this purpose are of a kind desirably conforming to occupation of space by the dial bracket 14, the dial cap d, the appurtenances carried by the dial cap, and the devices for operating these appurtenances.

Referring now to Figs. 1, 2, 3, 4, 5 and 7, as best illustrated in Figs. 1, 5 and 7 the latch ring 550 is provided with a gap closing annulus 565 adapted in one position to open the throat F through which the main yarn guides F to F move when put into or withdrawn from operative position. In another portion of the device 565 there may be provided another gap. at the opposite side from the main yarn feed, as shown at 566, Fig. 6, and. the latch ring 550 being appropriately recessed at 567, a yarn guide 570 for the auxiliary yarn may be entered into and withdrawn from the recess 567 to feed or cease feeding the auxiliary wave in needles N.

' Preferably as shown in Figs. 5 and 6 the yarn guide 57 0 is pivoted well above and substantially in line with the cylindrical surface defined by the needles at 571, and the motions of its yarn feeding end are revolutions of proper vertical motions of the pivot 571 and vibratory motions about the center 571. The guide 570 is adapted and arranged when in position in the recess 567 to provide by its interior face a continuation of the latch guard surface of the ring 550. At other times, the

gap closer ring 565 is relied upon to bridge this recess. For this purpose the gap 566 in ring 565 for the auxiliary wave may in its position of rest be further displaced from the recess 567 than is the gap at throat 1 so that a longer angular motion of gap closer ring 565 is required to open the auxiliary gap.

It is therefore provided to move the actuator ring 565 whenever the yarn is to be entered or withdrawn at F, and to move it further whenever the auxiliary yarn is to be fed or withdrawn from the auxiliary needle wave. For this purpose, see Fig. 1, there may be pivoted on the latch ring pivot standard 401 a lever arm 575 connected by a link 576 to the gap closer ring. A spring 566 tends to maintain the gap closer in its closed position. Lever 57 5 may be actuated through link 577 and two-armed lever 578 loose on the rock shaft 119 in frame 110. The lever 578 takes over and is actuated by one of the thrust bars of the series 465 as shown at 469. vAppropriate cams of different heights (not shown) on drum 120 shift the latch ring further whenever the yarn guide 570 is to be entered or withdrawn, and through a lesser angle whenever one of the main yarn guides feeding to the yarn throat F is to be shifted.

Assuming that the yarn guide 570 for the auxiliary wave is in the position shown in Fig. 5 and that the severed end of its yarn is held on the upper surface of the dial cap 03, devices are provided for placing the yarn guide 570 in position to be made operative to feed the needle waveon the next reverse stroke (in direction y, Fig. 16) of needle cylinder 260. The yarn guide 570 depends from its pivot 571 through a slot in the forward arm of the bracket 14. The pivot 571 is mounted in one end of a radius arm 573 pivoted at 574 to a bracket 57 5 erected on the latch ring. The radius arm 573 is pivoted at 576 to a trip 577 having a spur 579 normally in position to engage the upper surface of a stop 578. The upper end of the yarn guide 570 is provided with a cam surface 579 reacting with a fixed stud 580 on an extension of the bracket 575. The yarn guide 570 is also provided with a pin 581 adapted to rest on the upper side of a radius link 582 pivoted to bracket 575 and linked to a lever arm 583.

The auxiliary yarn guide passes to a preliminary operating position above and in line with the needles and is there stopped by the spur 579, whenever the arm 583 is dropped. Arm 583 is controlled to drop by attachment to a rock shaft 584, Figs. 3 and 7 at the back of the machine, which rock shaft is provided with an arm 585 having a stop 586 resting on a link 587 pivoted at 588. Fig. 3, to a lug on the standard 11, and connected at its other end to a vertical thrust rod 590, attached to a thrust bar and guided edge of which a shear blade i by the front .face resting against the stud 450, Fig. 3, and actuated by cams on drum 120.

The yarn guide 570 is to be dropped into operative position onthe reverse stroke of the needle cylinder. Whenever the trip 577 is moved' radially outwardly, the pin 580 determines an outward motion of the end of the yarn guide into the recess 567. When the arm 583 is operated upwardly 'the yarn guide 570 is moved upwardly and inwardly in respect to the needles and the center of the machine; the pin 581 may be stressed downwardly by a light spring 595.

To move the trip 577 there is pivoted on the bed plate 2 of the machine a vertical lever 591 having a hook 592 adapted to be moved outwardly by contact of the upper end of a lever 593 pivoted at 595 on bracket 103, having its lower end in contact with and to be moved by a part moving with slide 100, and adapted at its upper end to move'outwardly against a pin 594cm lever 591, to move the lever 591 to release the trip 577 whenever slide 100 is moved inwardly. This motion occurs prior to the first reverse stroke of reciprocation and after all of the needles N have passed the auxiliary cams.

Whenever the yarn for the auxiliary wave is moved upwardly and inwardly, it is'arranged to be received, clamped and severed on the upper surface of the dial cap 03. This will occur when the machine is about to resume rotary motion, as determined by actuation of the rod 590. One way of segering and clamping the withdrawn yarn is" shown in Figs. 7, 8 and 9. In addition to the usual yarn clamp P, Fig. 8, and the actuated yarn clamp f and actuated shears f, a clamp f carrying a leather block 7" may be pivoted at f on the lug f and be held so that the block 7" bears against a surface of the dial cap by a spring f", and be lifted to open the clamp to receive the withdrawn yarn by a link f and lever f pivoted on an existing stud 7 Fig. 7, and actuated by a link f", two-armed lever f, Fig. 1, and one of the thrust bars of the series 465 and cams .on drum 120. There may also be erected upon the upper surface of the dial cap a ledger blade f against one upwardly extending diagonal pivoted at f is actuated by a link f also connected to lever 7". As shown in Fig. 10 the link 7 may be attached to the lever for lost motion in the slotted hole f".

In order to avoid the construction just described for coordinating the motions of a mechanically actuated clamp and cutter with the operations of the auxiliaryyarn guide 570, resort may be had to a spring clamp q, Fig. 21, like the clamp f of Fig. 8, and to a fixed cutter g, which may comprise a triangular fixed knife blade held in a slot in the upper surface of the dial cap J and preferably protected by a u shaped guard g when it is desired to knit a widened gore, by the lift rod 684 having with crank arms 686 on and tending to rock thehorizontalelement of the usual universal mounting of the-widened pickers to throw them downwardly from the position shown in Fig. 15 to the osition shownin Fig. 17.

In machines o the kind described the length of stitch is controlled by lifting and lowering the column 280, for which the lever 281 reacts on a lug on the column 280 as

deg pickers

680, 681 may be controlled together, ,0

a finger 685 reacting termined by cams on the drum 120f but when it is desired to knit split tubular abric it is not desirable to move the drum 120 throu h considerable distances during reciprocal knit ting, and it is preferred to control the stitch len ths for the ankle and foot independently. Re erring to Figs. 1, 19. and 20, the stitch length lever 281 is forwardly extending at281 to provide for hearing screws resting respectively on a disk 83 attached to the shaft 80 and on a cam 83 formed on the hub of an independently movable ratchet wheel 83 having a segment without teeth. The ratchet 83 is free to rotate on the reduced end of the shaft 80, and may be stepped forward by a pawl plate 71 on the end of a pawl lever 72 ivoted 73 on a bent lever arm 74 wiped y-tl're hub of pawl 82. During the'operation\ of the machine other than for split tubular knitting the pawl 71 reacts ineffectively with the peripheral toothless segment 1. Projecting from is a pin 83 against 83 on disk 83', Fig.

and actuates teeth. There are enough ratch- "et teeth to move the cams on the hub 83' through a. sufficient arc and duringa suffi cient time to determine operation of the lever 281 to change the stitch length appropriately during progress of the split tubular knitting. The screw bearing-on disc 83 determines the lower position of lever 281 and the minimum stitch length.

The operation of the machine will now be evident. As described above the various agencies of the machine are coordinated by their several connections to the main pattern carried by the shaft 80 and its associated drum 120 to predetermine operation in the v drive the ratchet 83- with shaft 80 until the pawl plate 71 finds and then retired to make a.

' transfer instrument.

-to shaft 32) 120; at a succeeding course, the bight-taking and transfer instruments in dial d are advanced on a short motion of drum 120 by cams on block m to take bights at the places of needles depressed at cam 382; the instruments in the dial retire with their taken bights at the end .of a revolution of the needle cylinder; the machine knits plain circular web forthewelt W for a predetermined number of courses, whereupon chain 88 initiates a forward rack of the shaft 80 and drum 120, during which cams on block m are operated to transfer the bights to needles depressed by cam 12 but thereafter entering the main cams to knit. During the transfer operation the advanced needles are effective to prevent any part of the fabric, except the bights of yarn held on the transfer instruments, from accompanying said instruments into the plane of the needles, and also, by standing at either side of the path of an advancing transfer instrument, such advanced needles ensure proper registry of the transfer instrument with the needle which'has previously been lowered by the cam 12 and which now rises to enter the withheld bight on the Thereafter the machine knits as usual the plain fabric leg L, de sirably having changed yarn after the" welt on another short motion of shaft 80 and drum 120. At this yarn change the auxiliary jack cam 368 may be dropped to inoperative position, Fig. 16, by depression of rod 375, Figs. 2 and 19, and the pickers 650 may be lifted by

levers

652, 654. When the machine has produced suflicient fabric for the calf of the leg of the stocking, drum 120 is racked forward through several short steps to move lever 281 to shorten the stitches. When the predetermined place for the section If at the back of the angle is reached, chain 85 drops pawl 82 into a-tooth in rack wheel 81 preceding the teeth 81 and 81", moving shaft 80 and drum 90 snfliciently to shift clutch shifter 92 to change the motion of=the machineto reciprocal motion (pinion 35 clutched The accompanying motion of drum 120 results in changing the yarn at the main cams (thrust bars 460, finger F withdrawn, another yarn finger entered) in shifting the latch-ring gap closer; in putting into operative position, in the order named of slide 113 and deflecting cam A; auxiliary cam slide 100 (during passage of needles n at end of rotation of cylinder 260) moving slide 131 to enter cam B; in dropping auxiliary yarn guide 57 0 to position to enter yarn on the first reverse stroke before needles N pass the auxiliary cams in direction y, Fig. 16; moving rod 326 down to release latch 324 and entering web-holder cam 313 at the auxiliary wave in needles N.

The machine knits a predetermined number of splittubular reversed courses sutured together at a, 1), until as determined by chain to making the heel.

85, rack wheel 81 is moved forward at the end of stroke of pawl 82 by tooth 81 to shift This motion does not alter the position. of clutch shifter 92, but results in a yarn change at the main feed; in Withdrawing slide 100 and the auxiliary cams; in lifting out and latching up the webholder cam 313, in Withdrawing deflector cam B, and in moving the gap-closer ring 565 and auxiliary yarn feed guide 570 to the position of Fig. 5, and simultaneously opening clamp f and cutter f, if used, and thereafter (after passage by it of. the long butts N) withdrawing cam A and releasing the narrowing pickers 650. The needles N are now on an upper path above the main cams, and a narrowed gore for the heel is being knit on a diminishing series of needles n.

The chain 85 now initiates a short rack of wheel 81 (pawl 82, tooth 81*) which results in dropping the widening pickers into action by motion up of arm 685 and rod 684. If the widening pickers accommodate two needle butts at a time, pickers 650 may be left in operation; if the widening pickers take only one needle at a time, the lever 654 may be operated to hold the narrowing pickers outof operation. 1

When the last needle n has been picked down, at the end of the heel H, another short rack of wheel 81 restores the devices to the .same condition as when beginning the sections it, 2'. The formation of sole 8 and foot top 7 now proceeds to line zz,Fig. 23,whereupon rack wheel 81 is moved sufliciently to shift the clutch on shaft 32 to cause rotary motion. Concomitantly slide 100 and the auxiliary knitting cams; auxiliary yarn guide 570, web-holder cam 313, deflector cam A, the auxiliary yarn clamp and cutter; if used; and deflector cam. B are moved appropriately to cease function, and cam C is entered to depress any needles left too high to knit at the main cams. The main yarn may be exchanged. WVhen the ring of fabric 1, 1" has been knit at themain cams by plain circular knitting, rack wheel 81 is moved to shift the clutch to pinion 35. On this motion, cam A is entered to switch up the long butts N, and then withdrawn. The pickers are operated in the same way as for the heel, and rotary single course knitting at the main cams only is resumed for loopers rounds; all of the main yarn fingers F to F are thrown out of action to cast off, and at the same time the jack cam 368 is returned to operative position.

During reciprocal knitting from the beginning of the sections 71., 2', to the toe, the mo tion of shaft 80 having at that time turned ratchet 83" to present teeth to pawl 71, this has moved the cams at 83 to control the extension 281 of the stitch-length lever. This has resulted, according to the figure of these cams and the adjustment of the bearing screw v following them, in imposin desirable stitch length adjustment on the abric above the instep and in the foot, including the heel and toe. The heel and toe may accordingly be knit much slacker than the top of the foot and sole.

Since the auxiliary knitting cams 113, 114 are independently mounted, any different rela'tionof tightness of stitch for the sections It and s to the fabric in leg L, at z and at f may be arranged for by adjustment of their vertical position.
