The usual latch ring l2 is positionedover the top of lthe needlev cylinder and is pivotally connected as by arms Isl to some stationary part of the machine frame as indicated at I6 in Fig. 2. Said latch lring is provided with the usual gap I8 l for thereception lof theyarn guide iingers I9 (indicated generally in Fig. 2) and with the conventional anged guard ring which is.r otataf bly mounted for selectively opening and closing i said gap. The shear plate 22 carries` the usual yarn cutter and clamp v24 and pivoted yarn clamp 26 provided with aleaf spring 28 as shown in Figs. '1, 2, and 10. Said shear plate ,is supported in fixed position 'in relation 'to latch ringy l2 by a l rod 30 secured at its lower end to said shear plate and adjustably iixed as by a set screw l2 in a hub 38 ary sleeve 38 carried `by' said bracket.

' stationary sleeve 52. Said tube is provided at its -the guard ringfor opening and closing the particular reference to Figs. 1 and 3 of the draw- 458 vis driven from shaft 40 by gears 80 and 82. As here shown, the clocking mechanism Gear 80 is fastened to the upper end of shaft 40 comprises a tube 50 joumalled for rotation in a by a sleeve 54 integral with or otherwise fixed to said gear. Intermediate gear .82 transmits the lower end with a plurality of, here shown as two, motion of gear 80 to gear 58 and is mounted for yarn guiding fingers constituted by narrow tubes through which the yarn passes outwardly from the interior of tube 50. Said yarn guiding fingers are 'positioned for rotation close to the inner periphery of latch ring |12 for feeding yarn to the rotation on plate 10 about the shank of a pivot screw 85 whichholds said gear removable in position on said plate and in mesh with gear 58.

In accordance with the present invention, provision is made for raising the yarn fingers 54 upneedles N when the latterr are raised for this wardly 4away from the needles automatically purpose, it being understood that the pattern of when the needles are raised for knitting the heel the clocks or other design elements formed by and toe portions of the stocking, such raising of the yarn suppliedby ngers 54 will depend upon needles taking place in the Scott 8: Williams the needles raised in position to receive said yarn, the raising of appropriateneedles being accomplished by any suitable mechanismas that pro= knitting machine with which the clocking or patterning attachment of the present invention is embodied as illustrated herein. .Provision is also vided heretofore in circular knitting machines vof made for interrupting the rotation of the bobbin the type described herein. Yarn lingers 54 have standard of yarn fingers 54 in the raised position a circular'path which extends into groove 55 of of the latter. In order to 'permit said yarn finthe latch ring. Said groove receives and guides gers to be raised tube 50 is mounted for longitudinal movement in sleeve`52 and ring 14 on gap |8 and'is itself conventionally provided with plate 10. A spring 88 bears at one end on the a gap 59-through which fingers 54 can move into lower enlarged portion 90 of tube 50 and at its groove 55. When the gap 59 in ring 20 is thus other endY on the end 92 of sleeve 5,2, and therepositioned' to permit entry of fingers 54 into fore resiliently opposes. upward -movement of groove 55, the ring is positioned for opening gap tube 50 and yarn fingers 54 carried thereby. It |8. When the ring 20 is positioned to close gap will be understood that when tube 50 is moved to I8, the gap in the ring is out of registry with fingers 54 and the latter are prevented, by theV portion ofthe ring adjacent its gap, from .entering groove 55, but at that time the ngers are in retracted stationary position as will hereinafter be explained. Thus, yarn fingers 54 are rotated adjacent the needle circle. Said fingers 54 rotate at such'ispeed in relation to the needles N that yone of said yarn fingers supplies yarn to theA needles for forming the clocks at one side of the stocking while the other of said yarn fingers supplies yarn for forming the clocks at the opposite side of the stocking, whereby the clocks at one side of the stocking are independent of the clocks at the other side of the stocking thereby eliminating connecting or. iioating thread por.- tions extending from one line of clocks at one side .of the stocking to the line of clocks at the other side of the. stocking which in certain maf chines of the prior art were unknit and wre required to be eut from the stocking as hereinbefore explained. On'the other hand the clocks thus knit into the stocking .are firmly retained therein and loose ends of yarn or threads are eliminated.

raise the yarn fingers 54 above the needles when the latter are operative to knit the heel and toe portions of the stocking, bobbin stand plate 55 is raised, and clutch elements 50 and 52 are thereby automatically disengaged for interrupting the driving connection between said elements. For more quickly arresting the motion or tube 50 and of the bobbin stand when the latter is disengaged from its driving connection, there is provided a brake member`94 provided with a friction shoe 55 which is in engagement with tube 50 within sleeve 52. Said brake 94 is positioned within tubular extension 95 of sleeve 52. An adfiustable screw 99 is threaded into the outer end of tubularextension 98 for adiusting the friction of the brake on tube 50. It will be understood that the friction of said shoe 95 is insumcient to impede the rotation of said' tube when the -latter is driven, but in view of the light weight of said tube and associated parts said friction shoe. is effective to quickly stop the rotation of said tube and of the bobbin stand when the driving connection of the stand is disengaged.

The means for automatically raising bobbin standplate 55 comprises a roller |00 carried at one ed of a lever |02 which is pivoted intermediate its ends on a pivot screw |04 secured to a Tube 50 is fixed to and depends from the bobbin bracket extension plate |05. Outer .end of pivstand plate 55, centrally thereof, by means of a ,Y Oted lever |02 is prvidedwith a fixed upwardly sleeve 51 fastened to said `-plate and to said extending arm |08. Lever |02 is operated by tube. 'I'here is a releasable driving connection bea pivoted lever I0 connected by a link` ||2 to the tween plate `55 and a gear 58 constituted by a proupper end of arm |08. Lever ||0 is pivoted injection' 50 depending from the lower surface of termedatc itscndaas at H4. to some stationary plate 55 for'engagement by a projection 52 xed, part of the knitting machine in position to be ento a plate 54 fastened as by a set lscrew 55 to gaged at its lower end ||5 by a cam on the main A gear 58. Gear 58 rests on a shelf 'l0 fixedto of gear 58 and annular plate 54 is prevented by ting the stocking thereby to project andretractav retaining washer18 which overlies the inner top marginal edge portion of the\ top of gear 58 within annular plate 54. Retaining washer'18 isv .xed by pin 15. It will be observed that projection-\50 on plate '.55 and projection 52 on plate 54 drum |20 of the machine. It will be understood that lever ||0 is controlled by drum |20 forlowering and raising bobbin stand plate 55 and tube 50 at the appropriate times in the course of knityarn fingers 54, said yarn fingers effective or ineffective to supply yarn to the needles, as may be necessary in the course of theV automatic operation of the machine for making a stocking.

' AS shown more clearly in Figs. 1 and 6, there is provided a cilrved yarn guard bar 22 disposed inthe latch ring between the inner periphery of the latter and the outer edge of shear plate 22, for preventing the needles from tangling with the vyarn supplied to the knit web-by yarn'ingers 54. Guard bar |22 is fixed to a part |24 of the bracket 34 by a vertically extending bar portion |26 fastened to said bracket part |24 in any suitable way as by screws |28 (Fig. 7). There is also provided a yarn guard pin |34 positioned between barV 22 and the edge of plate 22, for guiding the yarn fed by fingers 54 'and attached tol the web below the shear' plate-22, said yarn 'engaging pin |34 betweenl said pin and guard bar |22. Provision is made for retracting pin |34 when` yarn ngers 54 are raised to retracted position. For

this purpose pin |34 is formed as part of an Lv shaped member |36 pivoted at its end |38 remote from the yarn-engaginz end of said`guard pin on a bracket extension plate |40,by means of a pivot screw |42 (Fig. 1). Member |36 is connected to leyer |02 by means of an adjustable sectional link |44 comprising apart |46 pivotally 'connected at its lower end" to ,memberl |36 and a part |48 the yarn supplied by said fingers and connected iso ' to the knit web; passes over plate 22, as the needle cylinder rotates, and is engaged by spring 28 of clamp 26 and cut from the web by cutter '24.

' As shown in Figs. 10 'and 11, plate 22 has a bevelled edge portion |53 for guiding the yarn into engagement with said clamps and cutter. ,/Referring now to the bobbin stand vhereinbefore mentioned in connection with plate 56 thereof, it will be observed that the yarn bobbins B are carried by plate 56, being removably secured for rotation thereby on pins |54 fixed to and upstanding from said plate. Suitable yarn tension'- ing and take-up means for the yarn from each of said bobbins supplied to the yarn fingers 54 are provided on plate 56. As here shown', there are two vertically disposed rods |56, each provided with a lower foot portion |50 for securement to the upper surface of plate 56, screws |60 beng provided for this purpose. A yarn guide hook |62 is removably secured by said screw |60 to the foot portion |58 of each rod |56. Each rod |56/ is provided with slot |64 extendinglongitudinally of saidrod for the major portion. of its length and transversely of said rod for the full width thereof. A yarn take-up sleeve |66'provided with a transverse aperture |68 is movable longitudinally downward movement of sleeve |66 and resiliently urges sleeve 66 toward the top of the rod.- A

yarn tensioni g device |12jis removably secured to the top of each rod |56 by aset screw |14'. It will be runderstood that the yarn Y as it leaves its bobbin is engaged by the spring-pressed plateA |16 of its companion-tensioning device' |12 and passes through an opening |16 (Fig. 9) in block to rod |56.

- guide hook |62 on its companion rod- |56, and then it extends upwardly and passes through the aperture |68 in sleeve |66 and through the slot |64 in rod |56 frein one side of saidrod to the other end, and n'ally the yarn extends downwardly-into one of the openings |82 in disc |84,

dles from the side of .cylinder at which yarn l0 fingers 54 arelocated .and to which 'yarn is supplied to said needles by said iinger to a diametrically opposed point in theV circular path of the needles. During approximately the other half of the revolution of the needle cylinder take-up sleeves |66 move upwardly thereby taking up the slack in the yarn. It will be understood that as the yarns supplied by the needles 54 are knit P/ into the web the tension of the spring on the take-up sleeves increases sufficiently thereby to tensionthe yarn for withdrawing` the necessary amount of yarn from the bobbins through the companion tensioning device` |12. f

Thus it is seen that the constructions herein shown or described are well adapted to accomplish the several objects of the present invention..

It will be understood, however, that the invention i may be embodied otherwise than as here shown and that in the forms of the invention herein disclosed, certain changes in the construction and arrangement of parts may be made and will read` ily occur to lskilled artisans, particularly in View of the presentdisclosure'. Therefore I do not wish to be limited precisely to',the construction herein shown or described, except as may be required withn the scopev of the appended claims.
