In the drawings, wherein for the purpose of illustration are shown preferred and modified embodiments of the improved knitting machine and the details thereof, the letter A may generally designate the improved knitting machine. It includes a frame B having a rotary cylinder C and a dial D. Drive means E is provided for driving the cylinder C and bed of the dial D, and for operating a pattern. control drum arrangement F and a pattern chain G. A set H of dial needles is provided and also a set K of cylinder needles. Selective means L is provided for operating the dial needles for various purposes, and a takeup mechanism M is provided -for taking up the string of tubular fabric N as it is knitted.

The frame B of the machine includes a cabinet portion 25 within which the drive mechanism of the machine is mounted. The frame is supported upon suitable legs 26 or in other manner and it has a top table 21 which supports the cylinder for vertical movement.

The cylinder C is longitudinally slotted on the outer surface thereof for reciprocably receiving needles .and jacks therein; the needles being mounted in the upper part of the cylinder and the jacks in the slots below the needles in the usual manner. An anti-friction bearing construction 30, shown in Figure 4 of the drawings, has a race directly supporting the lower end of the cylinder C; this anti-friction bearing 30 being supported in a ring-shaped cup 3|. The cup 3! is suitably bolted or riveted as shown at 33 in Figure 2 of the drawings to the upper end of a vertically movable supporting bar 35. The bar rod 35 is slidably supported in suitable brackets 36 provided upon the frame of the machine. A spring 31, shown in Figure 2 of the drawings, normally holds the bar 35 downwardly, and at its lower end it may rest upon an adjusting screw (s8 as shown in Figure 2. This cylinder supporting bar 35 may be elevated by means of a lever 38 which is pivoted at 39 on a frame bracket of the machine, as shown in Figure 2 of the drawings. The lever 38 is operated off of the section F of the pattern control arrangement F, and at its other end the lever 38 may engage a pin 40 which is integral with the bar35. A lug on the drum F will depress the lever 38 at its drum end and thus elevate the cylinder in a manner which is apparent from the drawings.

The cylinder C at its lower end is upwardly slotted, as shown at 4| in Figure 2 of the drawings to receive therein sectors 42 of the ring gear 43 inwhich the cylinder C is movably mounted, as shown in Figure 4 of the drawings. The gear 43 is socketed in the supporting bed 21 of the frame B, as shown in Figure 4. A cap plate 45 is secured at 45 to the bed 21 for the purpose of maintaining the ring gear 43 rotatably in place. The gear 43 is of the bevel herring-bone type.

The top construction of the cylinder is rather conventional. It includes a top ring 50, for slidably supporting the sinkers 5|. The sinker control arrangement further includes the sinker or web holding bed 52 whichis keyed at 53 to the cylinder. The sinker cam ring 54 is mounted on the bed and of course is provided with movement limiting lugs 290 thereon, best shown in Figures 15 and 16 of the drawings, located at opposite sides of a stop post 29! (see Figure 1) as is usual in circular knitting machines of this general type.

The sinkers 5! are of general construction and need not be further described, since their nature, function and construction is well understood in the art to which this invention relates. Reference in this connection may be made to U. S. Patent #1,467,691. The sinker cam cap 54 has an annular channel in the undersurface thereof, in which the butts of the sinkers ride. In this channel the sinker cam ring 54 is provided with a sinker withdrawing cam and sinker advancing cams 6| and 62. The advancing cams GI and 62 are pivoted at their proximate ends at 63 and are adapted to be retracted at different operations throughout the knitting of the stocking. Means is provided to move the advancing cams (ii and 62 comprising a circumferentially movable ring socketed in an annular channel in the top of the cam ring 54, as is shown in Figures 4 and 15 of the drawings. This ring 65 is provided with cams 65, slotted to receive pins 61 of the cams 6! and 62 and having throw portions 65 to move the cams 6| and 62 to a retracted position. Cams GI and 62 are advanced and retracted as the ring 65 is reciprocably moved in its channel on the sinker cam ring 54. A spring 64 normally maintains the cams 6| and G2 in sinker advancing position.

Referring now to the pattern control drum arrangement F, with reference to Figures 2, 3 and 13 of the drawings it will be seen that this drum arrangement is compactly located at the rear of the machine in an easily accessible and convenient location. It essentially consists of a shaft 15 rotatably supported and connected by brackets v I6 to the frame of the machine; one of the brackets 16 being located intermediate the ends of the shaft 15 to give it central support. The drum arrangement includes the drum F and the drum F" and on these drums a circumferential series of lugs are provided for operating the various levers and parts of the machine. A compact and accessible arrangement of levers includes a shaft 11 which is rotatably supported by the brackets 16 of the machine; said shaft extending parallel with the drum and at a location between the drums and the cylinder, and on a level approximately in a line tangent to the top of the drums. On this shaft 11 are located bell crank levers which are pivoted for cscillative action thereon; the said bell crank levers having arm portions which operate at their ends on lugs on the drum, the opposite ends of said levers extending substantially vertical and having rod attachments with the different features of the machine to be operated. With reference to the sinker cam control ring 65 immediately above cessible and-so that the dial may be moved to described, one of the levers -10 of the shaft 'I'I has the upper end of its vertical arm supporting a connecting rod the opposite end of said connecting rod being attached in a suitable opening 02 provided in the ring 65 (see Figures 3 and 15). Rocking of the lever 19. incident to operation off the drum F" will causemovement of the 'ringIiS and throw the cams 6| and. 62 into ret'racted position (see dotted lines in Figure 16).

The drums F and F" are keyed at 83 to the shaft I5, and the shaft 15 has also keyed therewith a ratchet wheel 85. To insure uniformity of movement advance of the shaft I5 at one side of the machine beyond the support I6 the shaft I5 i s'provided with a brake d 00 and toothed detent wheel 81. A spring actuated pawl 81 is pivoted at 88 on the frame of the machine (see Figure 14). A tooth 80 is located in the recesses between the teeth on the wheel 01 to restrain too free advance of the shaft 81 except as hereinafter noted. A brake band 08 acts continuously on the drum 86 to prevent loose play in the shaft I5 and thus prevents the forward or backward movement of either of the drums F' or F" except as advanced by pawl mechanism to be hereinafter described. The shaft I5 is provided with a freely rotatable sprocket wheel .90 thereon around which the pattern chain G is (see Figure 6) which is broad enough to operate in the teeth recesses of both of these ratchet wheels 05 and SI to maintain them in their proper relationship. 1 The pattern chain G is of course trained over the teeth on the sprocket wheel 00. This chain is relatively long since it is intended to provide in it one link for each knitted course throughout the length of the stocking or article being knitted. In order to accommodate the chain a special frame is provided consisting of a supporting standard 94, as shown in Figure 6 of the drawings, connected in depending relation from the machine frame, and having upper and lower support bars '05 and 90 respectively. These support bars each have.a series of rotatable wheels or rollers 91 thereonaround which the chain 'G-is trained. The frame of the machine may additionally be provided with rollers 00 around w Ich the chain G is trained as it comes direct fro the sprocket wheel 90 prior'to the zig zag. training of the chain over the rollerson the upper and lower support bars 95 and 98. As will be noted from Figure 1 of the drawings this chain is located in an out-of the way relation .at therear of and beneath the frame of the machine, below the drive mechanism control box or compartment in the machinehas shown in Figure 6. I I

Referring to the dial construction vD and the selective means L for operating the diar needles thereof, a very compactbracket or yoke con-- struction is provided for supporting the di mechanism over the cylinder in such manner that all of the parts of the same are readily ac? f an out of the way position with respect to the struction for the dial is generally of inverted U shape formation. It includes a stationary bracket I00, at the left side of the machine.

. bolted at IN to the machine bed 21 and extendsupporting portion [06 which lies horizontally over the cylinder, as shown in Figure 4. The yoke construction for supporting the cylinder further includes the bracket arm I01 mounted on the bed of the machine ,at the opposite side from the bracket I00, as shown in Figure 1 of the drawings, and which extends diagonally upward inclined towards the cylinder and at its upper end is adapted to receive the free end of the dial supporting arm I04 in resting relation thereon; an adjusting screw I08 being provided on the end of the arm I04, for abutment with the upper end of the arm I01, to regulate the spacing of the dial above the cylinder when in knitting position.

The horizontal portion I06 of the dial bracket swinging arm I04 is provided with a non-rotatable depending shaft I09, shown in Figure 4 of the drawings, and which'is bolted thereto at I I0; "an annular stop flange III being provided thereon to abut the under surface of the arm I06 and enable the'shaft to be properly bolted into position. A rotatable sleeve H5 is mounted on the lower end of the shaft I09 in position to beaxially aligned with the cylinder C when the swinging arm I04 is in the position shown in Figure 4 of the drawings. This rotatable sleeve H5 is maintained detachably on the shaft I09 at the lower end of the latter by means of a nut cylinder. This sprocket or supporting yoke'conus and supporting washer ill, and it is on the lower end of this sleeve II5 that the dial bed II8 of the dial construction D is keyed, as by a detachable pin H9. The sleeve H5 at its upper end is provided-with a gear adjusting plate I20, keyed at I2I, as shown in Figure-4 to the shaft] I5. A gear I22 is rotatably located in a recess or socket provided in the bottom "surface of the swinging arm I04; said gear being centrally apertured to receive the flange I I I of the shaft I I5 as shown in Figure 4. This gear is adjustably keyed or attached to the adjusting plate I an of course the drive of the machine driving the gear I22 will thus drive the sleeve I I5. and rotate the dial bed 8 therewith in synchronism with the cylinder C as will be subsequently described. The timed adjustment of the gear teeth relative to the drive shaft I I5 is angularly secured by providinga'depending lu'g I23 on the'gear'l 22', as shown in Figure 5 of the drawings, which depends between two extensions I24 and I25 on the adjusting plate I20; adjusting screws I26 beingprovided on the plate extensionscl24 and I25, in order to. angularly adjust the gear I22 insure attachment of the gear to the plate I20- ;when the properptiming has been obtainedbolts I20 may be tightened. These bolts I20 are screw threaded in socketsin the plate I20, as shown in Figure 5, and the gear I22 is provided with slots to receive the shanks thereof.

.relative to the rotatable sleeve H5. In order to The dial construction includes the bed H8 and the stationary dial cap I23. This dial cap is in the form of a ringso that the lower ends of arrangements which may be provided on the dial needles in order to move them for accomplishing various operations.

Refen-ing now to the dial bed construction I I3, as is shown in Figure 7 ofthe drawings, the same is provided with slots I3I which reciprocably receive the needles I32 of the set H of dial needles.

The dial needles I32 each include a body portion I 33 having a shoulder I 33 intermediate its ends behind the points where the latch closes. The needle has the usual hook end latch. Immediately rearwardly 'of the shoulder the body I35 is laterally recessed upwardly from the lower edge thereof, at I31. Facing this recess is a spring arm I33 which at its fore end is free of direct attachment to the needle and is provided with a lip I33 adapted to fit in the recessed portion I43 in the lower edge of the needle. The arm I33 is spring bowed as shown in the upper corner in Figure 19 of the drawings and faces the'concaved recess I31 in the body of the needle to provide an eye which is vertically disposed when the dial needle is positioned in the dial bed. The head of the cylinder needle may readily slip into this opening notwithstanding that the cylinder needle is directly opposite the line of travel of the dial needle. The lip I33 prevents the stitch catching in the eye. The arm I33 compresses into the position shown in the middle view of Figure 19 when the dialneedle is retracted in the groove of the dial bed. Upon projection of the needle the stitch catches against the shoulder I33 and is spread open by the arm I38 so that the cylinder needle, may readily enter it as shown in Figure 21. The

dial bed II3 has the grooves I3I widened at the fore ends thereof. 4 I

The dial cap I23 is best shown in Figures 4 and 8 of the4irawings, and in dot and dash line application of the cams and cam grooves thereof to the dial needles is shown in Figure 1'1. The dial cap has a central opening I42 to receive the lower ends of the dial needle actuating fingers I 33. The dial needles are projected bythe fingers I" both for transferring stitches fromdial needles to cylinder needles and at a second location to receive yarns when they are used in connection with the cylinder needles for knitting rib work. .The dial cap I23 is provided with the dial needle butt receiving groove I44 which receives the dial needles when they are inactively positioned. The'dial needles are projected into stitch transfer position by a cam I45, comprising part of the dial cap, when the butts of the needles I2 are thrown into the groove I43 'surrounding this cam. Norma1ly, thev butts of selector fingers I33.

is cut away at I3I soas to enable the fingers I33 to project the butts of the dial needles into engagement with the cam I33.

The compact arrangement for mounting the dial needle selector fingers I33 comprises a supporting collar or member I33 keyed at I34 oh the sleeve II intermediate the ends of the latter. This support I53 has an annular fulcrum flange I53 thereon for the fingers or members I33. These members I33 are provided with upper and lower portions I33 and I33 above and below the fulcrum point respectively which are disposed in any angular relation with respect to each other. When the fingers are mounted on'the fulcrum fiange I53 the upper portions I311 will be vertically positioned, and the lower portions I33 will be relatively convergent towards the axis of the shaft. The fingers I33 are bowed to provide fulcrum recesses I33 on the inner sides thereof which fit upon the fulcrum flange I53. In this manner the dial needle control members are arranged in close fitting annular relation and the lower ends thereof are normally positioned in the central opening of the dial cap. The lower ends are held in abutment with the sleeve II5 by means of compression springs I 33 shown in Figure 4 of the drawings. In order to prevent lateral play of the fingers or members I33 suitable filler pieces may be placed between them. These filler pieces will of course be substantially the same shape as the members I33 except that they are not provided with butts or means for operating against the dial needles. The lower dial needle engaging ends of the members I33 may be shaped in any fashion suitable to the mode of operating against the dial needles. At their upper ends the fingers I33 may be provided with any desired arrangement of butts thereon. In the example shown in the drawings substantially one-half of the members I33 are provided with butts I33 at an upper level and the remainder of the said dial needle control members I33 have butts- I3II at a lower level. The-upper level butts I33 are arranged, as shown in Figure 9, over substantially one half of the short butt cylinder needle.

section and substantially one half of the long butt cylinder needle section;

In the present invention the dial needle selector members I33 are adapted to project the \dial needles merely at the stitch transfer and yarn receiving points. It is quite evident that the projection of the dial needles may be used for other purposes than herein enumerated. For instance, they could be selectively projected to take any desired arrangement of the yarns, such as patter ng and wrapping yarnsfetc.

. Referring to the means E for driving. the dial and cylinder, the drive shaft of the drive mechanism includes sections I33 and I33", and a ,main drive shaft. They are not keyed together bxcept through the intermediary of clutch mechanism to lie-subsequently described. The section I33 has 'a herring-bone bevel gear I33 which meshes with the cylinder gear 43 for drive of the said cylinder. The section I35 also has keyed therewith a smaller bevel herring-bone gear I31 which may be bolted directly to the .gear I33. The beveled teeth on this gear I31 face directly opposite the bevel of the teeth on is provided with a herring-bone bevel gear I12, which meshes with the teeth of the gear I22, and drives the latter. The lower end of the shaft I'III within the compartment of the cabi- 5 net of the machine below the bed is provided with a herring-bone gear I14 meshing with the teeth of. the gear 161. These gears and parts are compactly associated and it is to. be particularly noted that the arrangement eliminates m the necessity of a horizontal counter shaft. The

elimination of all gearing except direct con-- nection between the drive shaft of the machine and the dial does away with unnecessary back slapand loose play in the gears, so that 15 it is possible to accurately regulate the relation of the dial needles to cylinder needles, and to effect the various delicate operating positions of the parts which are vitally necessary during the knitting of continuous strings of stockings of the character set forth in this application.

A clutch hub I69 is splined at I10 upon shaft section I65 and adapted for selective clutching with either a spur gear III which is keyed directly to the shaft section I65 at H2, or with the gear I15. A pulley I'I6 idles on the shaft. section I65, and said shaft I65 may also have a hand crank thereon best shown at I'll, and used in the usual manner. The shaft section I65 has asecond pulley I'II directly keyed to the shaft I65 The third pulley HR is rotatably mounted on the shaft section I65 by a sleeve section I19 integral therewith which bears in a Wall of the frame B of the machine, as shown in Figure 11. This sleeve I19 at the inside of the drive gear cabinet of the frame' has a spur gear I80 keyed directly therewith. A countershaft I8! is rotatably mounted on the wall of the frame B and it has thereon a pair of freely rotatable gears I82 and I83; the latter meshing so with the teeth of the spur gear III The gears ili I88, I82 and I83 comprise'a compound high speed means for driving the shaft section I at -'a high speed. The direct drive of course r9 ates the cylinder at' a lower speed. Meshw ing with and directly back of the gear I86 is a larger gear I85 (see Figure 6) which has a crank pitman I8S'eccentrically. pivoted thereto. A pivoting gear lever 'IB'I ismounted intermediate its ends upon a shaft I88 below the no main drive shaft assembly. It has a segment shaped end I89 provided with gear teeth I93 which mesh with the teeth of the gear I15. The latter is loosely mounted upon the shaft I65. The lever I8'I'is reciprocated when the gear I85 05 is rotated, and thus oscillatively moves the gear W5. When the clutch hub I69 is in engagement with the gear I15 it can readily be seen that the cylinder will be reciprocated for knitting the heel and toe pockets.

" E Referring to the means for advancing the-- drum assemblage F, and to rotate the sprocket at in order to advance the main pattern chain G, a bell crank lever I95 is pivoted at I95 a operates off of roller lugs on the gear I85. These lugs hit the lever I95 at one end to throw pawls 200 and 2M which are on the other end thereof into respective, advancing engagement with the teeth of ratchet wheels 8| and 86. Both of these pawls 200 and 2III are mounted 7 on the lever I85 and --are spring urged into engagement with the teeth of the ratchetwheels. There are eight lugsv or rollers on the gear I6 whichfoperate the lever I95. Four of them, designatedat 202, are radially set back farther than the othertfour 204, so that the throw of surface of the foot 2'.

the bell crank lever is greater when the rollers 204 are hitting the lever than when the rollers 203- engag'e it. a The purpose of this will be subfoot 2 which forms part of the oscillating 10 lever I81, at the opposite side ofthe shaft I88 with respect to the segment I89. A spring 2I8 normally holds the roller 2II) against the cam Of course oscillation of the arm I81 will advance the pawl 201. 15

The chain G hastwo longitudinal series of lugs along it, arranged along the lines -2I5- and 2 I6 designated in Figure 12 of the drawings. vers.2II and 2I8 respectively pivoted at 2i! "and 220 on theshaft 11 are adapted for cooperation with the lugs along the lines H5 and 2H; respectively of the chain G. As shown in Figure 6 of the drawings these levers 2I'I and 2I8 are normallyheld in engagement intermediate their ends with the chain, in the line of 25 the lugs, by means of springs 222. The lever 2II is provided with an arm 223 thereon which normally holds the pawl ZIlI out of action. A lug onthe chain G raises the lever Zil which will release the pawl 20I for action upon the ratchet wheel 85. The lever M8 is provided with an arm 224 which normally holds the pawl 2M out of action, but when a lug on the chain G lifts the lever 2I8 it will move the arm 226 at an upper level. They are positioned in an alternating relation with the cylinder needles,ands as similarly jacks 23% having short butts at the up per level (complementary to the decks 236) are provided in alternating relation below the cylinder needles. These short butt upper level jacks 235 are spaced across the division line of the long and short butt needles, that is, half of them 1 are in the long butt needle section and half ,of them in the short butt needle section, and that is also true for the upper level long butt jacks 234, for a purpose which will be subsequently dem scribed. It should be noted in this connection that the upper level short butt jacks 235 are located below cylinder needles which are inactive during rib knitting and which receive stitches from the dial needles actuated by those dial neeso die actuating fingers I having the butts I thereof at the lower level.

The frame bed 21 of the machine has a cam supporting ring 'or table 240, which is spaced ure 1 of the drawings which are bolted to the go bed 21. The table 240 supports main stitch cam block 2, shownin Figure 4 of the drawings;

the widening pick attachment 430 shown in FIG- ure 1 of the drawings, and other cam and cam operating levels to be subsequently-described. w

The machine is preferably provided with yarn feeds in the nature of the usual levers pivoted at 245 on the latch ring .245. This latch ring is bolted at 241 upon the swinging arm I55 of the dial supporting structure I54 (see Figure 4) and the dial cap I25 is in turn bolted at 255 to the latch ring to hold it against rotation.

The five yarn feed fingers are used for feedin plating, splice, top, binding, and lining yarns to the needles. The finger 252 which feeds yarn for the knitting of the rib top also is used to knit the heel and toe of the stocking. By reference to Figures 2 and 3 of the drawings it will be seen that these fingers 255 to 254 inclusive are swung into action by means of reciprocating push rods 255 (see Figure 2) supported by brackets 251 on the machine. These push rods 255 in turn are actuated by suitable levers 255, 255, 255, 25I and 252, for the fingers 255, 25!, 252, 255, and 254 respectively. Thelevers 255 to 252 inclusive are pivoted on theshaft 11 and at their outer ends are raised by lugs on the drum F for throwing thepush rods 255 into: engagement with the respective yarn fingers.

At the location of transfer of the stitches from dial needles to cylinder needles a brush 254 is located for throwing the latches of the needles open.

As before mentioned the dial needles are partially advanced by the selectors I55, both at the transfer and stitch actuating cams of the dial. In order to support the cams or levers for selective actuation of these fingers I a segmental shaped supporting piece 215, as shown in Figures 1 and 3 of the drawings is mounted by means of brackets, 2 attached to the skirt of the bracket I55 which supports the dial construction. Upper and lower levers 212 and 215 respectively are pivoted at 214 upon the supporting segment 215 for respective action upon the upper and lower level butts of the dial selector fingers I55. Thus, the lever 212 cams against the butts I55 and the lever 213 cams against the lower butts I55". These levers 212 and 215 are respectively connected by rods 215 with levers 211 and 215. These levers 211 and 215 are pivoted upon the shaft 11 and are lug actuated off of the drum F. They are bell crank levers as can clearly be understood from Figures 2 and 3 of the drawings. The yarn receiving and stitch forming location on the dial for the dial needle actuating fingers I55 is provided with another pair of actuating levers 255 and 25I which are pivoted at- 252 on the support 215. These levers are pro vided with cam portions for operating respectively on the upper butt and lower butt dial needle selector fingers I55. These levers 255 and 25] are thrown into and out of actuating relation by means of levers 254 and 255 respectively. These levers 254 and 255 are pivoted on the shaft 11 and have connecting rods 285 which connect them with the cam levers 255 and 25I.

It was before mentioned that the sinker cams H and 52 are opened and closed at different op-- erations throughout the stocking. Inasmuch as the sinker cap oscillates during reciprocation of the machine, as limited by the lugs 295 thereon engaging against the lug 25I (see Figure 3), it

will be desirable to hold the sinker ring 54 against movement when it is desired to advance the cam ring 55 for throwing the sinker cams 5| and 52 lever 255 is actuated off of the lever 255 and the latter is pivoted upon the shaft 11 and actuated off of drum F. It is connected by meansof a rod 255 with the lever 255 above described.

The'frame of the machine is provided with a bobbin supporting table 555 'rearwardly of -the lever arrangement which operates oil. the lugs of the drums F and On this tableare supported bobbins "I for feeding the various yarns to the feed fingers 255 to 254 inclusive. Figure 2 shows the arrangement of yarns. Plating yarn is indicated at 552, the splice yarn is indicated at 555, the heel, toe' and rib top yarn is indicated at 554, the binding or selvage yarn is indicated at 555 and the lining yarn is indicated at 555. All of these yarns except the yarn 554 are fed through appropriate tensioners 551 and then extend to their respective feed fingers 255 to 254 inclusive.

The rib top yarn 554, which is also used in knitting the'heel and toe has the normal tensioner 555 operating thereon, and it is provided with additional tensioning means which may be released as desired. This includes a conventional tensioner 5I5 having upper and lower plates between which the yarn passes. The lower plate is movably supported by an arm 5I5, shown in Figure 2 of the drawings, which is pivoted at 5I5 and normally spring urged at 5" into tensioning position. A connecting rod 5I5 is attached to the arm 5I5 and moves upwardly and downwardly to throw the tensioner into an'd'out of 'action. The

rod 5I5 is pivoted at its lower end to a lever 525 which in turn is pivoted at 52I upon a bracket of theframe of the machine, as shown in Figures 2 -and 3 of the drawings.

Thislever 525 is connected by a rod 525 to one of the drum actuated levers 524. The drum actuating lever 524 is pivoted on the shaft 11 and lug actuated off the drum F. in order to throw the yarn tensioner 5I5 .into or out of yarn tensioning position.

Means is provided to hold the splice yarn in an out of the way relation with respect to the dial during knitting of the highsplice heel and double sole during rotary knitting, since otherwise the 'dotted position it is across the cylinder needle line'and in position to engage the splice yarn and guide and maintain it below the dialdn an out of the way relation until the splice yarn is taken by the needles which are intended to take it during the next rotational movement. This guard finger 545 enters across the needle line at the knitting wave opening in the cylinder needle set directly above the low point in the stitch cast-off cam, as shown in Figures 9 and 10 of the drawings.

The splice yarn finger 545 is mounted upon a movable supporting plate 5, slotted at 542. A

screw or pin 545 on the cam ring 54 supports the splice yarn guide member for reciprocatory movement into its operative and inoperative positions. A pin 544 assists in guiding the movement of the splice yarn guide. A spring 545 normally urges an edge of the guide 3 against the pin 544. and a spring 546 normally throws the yarn guide to an inoperative position as indicated in the full line view of Figure 15 of the drawings. Referwith Figures 15 and 16 it will be noted that a lever 350 is pivoted on the same pivot 294 as the lever 293; said lever 358 having a bifurcated end which engages a pin 35l on the splice yarn guide plate 340 for the purpose of advancing the splice yarn guide 348 into operative position as indicated in the dotted lines in Figure 15 of the drawings. 'This lever 350 is operated 01f of a lever 352 pivoted on the shaft 11, as shown in Figure'3.

A binder and cutter for cutting and holding the yarns is mounted upon the dial cap I29 of the machine. This binder and cutter is generallydesignated at 368 in the drawings. As shown in Figure 23 the binder and cutter includes a shaft 36i mountable by suitable brackets 362 on the dial cap I29. A binder arm 393 is spring urged at 364 for holding yarns after they are severed, and a loose pivoted binder 363 cooperates therewith. The shaft 36! is provided with a cutter bar 366 which operates in a depression in the dial cap to sever the yarn. This cutter-is normally spring urged into buttingposition by a spring 368. An extension arm 313 on the cutter bar 366 engages the arm 383 to lift the latter when the cutterbar is moved to an open position. This extension-310 has a link 31! which is provided with an opening therein. The latch ring 246 is provided with a support 315 with which a yarn cutting operating lever 316 is pivoted as at 311; this lever 316 loosely extending into the link 3H for raising and lowering the cutter bar. The means for operating the lever 316 consists of a lever 388 shown in.

Figures 3 and 4 oi the drawings, pivoted at 3 8l upon a suitable bracket mounted upon the latch ring; this operating lever 389 having a pin at its free end adapted to operate on the lever 316.
