Fig. 33 is a side view of one of the pull ,ba-rs, its slide and the ratchet driven thereby. Fig. 34 is a side View of another one of the pull bars and the `means' operated thereby. The machine has a revolving needle carrier 1, the needles being indicated at 2.

There is a group of main yarn guide tingers at each side of the machine, these being for diderent colors of kinds of yarn. The fingers 3 of each group are pivotalfy mounted side by side at 4 in brackets 5 tired tothe sinker cam ring 6 which is held against rotation by a stud 7 extending 'from a bracket. 8, said stud entering a notch in the cam ring.

The main yarn fingers 3 incline downwardly and inwardly from their pivots towards the axis of the machine and feed the yarn to the needles through mouths 10, 10 of a latch guard ring 11 iXed by screws 12 to the stationary top plate or sinker cam ringy of the machine. These fingers are thrown down into operative position by vertical push rods 13 mounted toslide in the brackets 5. '.These push rods are operated selectively by a plunger 14 which is positioned under the proper push rod by' the slidably mounted in the bracket 5. The low-V er end of the plunger rests upon a lifter plate' 16 which is of sufficient width to insure contact with the lower end of the plunger in all positions to which the latter may be moved by the carrier according to the demands of the pattern mechanism, as will be described hereinafter. This lifter plate is pivoted at 17 to the fixed bracket and it has a roller 18 designed to be acted on by a rotary cam member 19, ixed beneath the rotary sinker bed, This cam operates the lifter, at each revolution of the machine, and if the plunger 14 has been moved by its carrier 15 to a position under one of the push rods 13 (there being four in each. group) the rise Vof the outer end of the lifter will elevate the plunger and cause it to push up on the proper rod 13, which, acting on the tail 3of the yarn linger, will throw this down to feeding position. The cam 19 has an incline 19 which gives to the roller 18 its downward movement suflicient to lower the yarn linger, as just stated, to feeding position. It4 has an additional rise 19 which gives the yarn finger a slight additional downward movement, the result of which tion 3 of the depressed finger will throw down a latch plate 20, and as soon as the'finger has reached its final position the latch plate will rise under the action of its spring 20 and said operated yarn linger will be retained in its operated Aposition to continue feeding the yarn. The same action, just described, which results in the depression of the latch plate by the movement of the operated yarn linger downward to feeding position, will release any one of the yarn 1ingers of this group, so that this will rise and withdraw its yarn from work. This rise of Athe released yarn finger'will he due to the action of the spring 3"* with which each yarn finger is provided at its pivot. Fig. 1 shows one finger in low or feeding position held by the latch plate and the upperor released position of one ofthe fingers is also shown. The release of a finger from feeding position, above mentioned, is due tov the fact that when the new yarn finger is thrown down, its projection engages and presses down the outer end of thelatch plate by working against the upper surface of its upstanding latch portion and carries this low enough to release the projection 3 of the finger which has been feeding. Any push rod 13 which may be operated, can fall down to normal position-as soon as the plunger 14 moves away from its lower end, and in this lowered position the push rods rest upon the upper surface of the plungers carrier block 15. The plunger itself is under tension of a spring 14 (seated between the wallsof the carrier, which is channel shaped) which forces 1t downward when the lifter plate 16 falls. In its upper position the plunger will be retained by a detent 14 which is in the form of a leaf spring 14X having the detenta projection 14 to enter a notch 14*L in 'the plunger, i. e., the same notch which the end of spring 14 lies in, but this happens only when the carrier 15 is at the left hand limit of its stroke, which is its normal position. The holding up of this plunger also has the effect of keeping t-he lifter plate 16 up,so that its roller, which is then down, will not be hit by the rotary cam 19, and therefore the lifter plate will not fiap up and down idly. This condition is illustrated in the right of Fig. 1. lVhen, however, the plung` er carrier 15 is moved to the right, Fig.y 2, from its vnormal position of rest at the left ofthe group of push rods, the plunger will move away from and will no longer be reis that a projec-frelease to inoperative position under the action of tained by the detent, and hence the spring of the plunger will force it .down and thus tip the lifter plate into position, so that its roller ywill be within the range of the cam 19 and hence will be Ioperated by said cam to swing the outer end of the plate upwardly and thus raise the plunger to move the proper yarn finger into feeding position and the other finger, so that it may rise its spring. This downward movement of thev plunger when the carrier moves to the right is due also to its working against an inoline 14" on the frame or bracke.

The plunger carrier is moved towards thev right from its left-hand position shown in Fig. 2, by pattern mechanism as follows:

A rod 21 connects the sliding carrier with a lever 22, fixed to a shaft 23 mounted in the fixed bracket 8 supported on the fixed base 24 of the machine. This shaft 23 is operated by an arm 23 whose huh is pinned thereto at 23, the depending end of which arm engages a notch 25 in a slide 25, Figs. 3 and 12, which has pivoted at 26 four pull bars 27. Fig. 3, each of which rest-s upon one of the pins 28 mounted in a carrier har 29. so as 'to slide freely therein, in a substantially vertical direction. This .carrier har has movement up and down to the perfo rated pattern strip or jacquard device which in the present case consists of an endless sheet of flexible material, as paper 30', passing over a pattern drum 30 referred to more fully hereinafter. The up and down movement of the pin carrying bar is derived from a cam 31 arranged coaxially with the needle cylinder and 4 roller 32 carried hy a slide 33 which is guided in the brac et 34, Figs. 2 and 4. This slide hears against an eccentric pin 35 carried by a rocking arm 35 which is pivotally mounted at 36 and is connected with an arm 37 which has thereon the pin carrying har 29. A spring 38 presses the arm down and the cam 31 through the connections described, raises the pin carrying har. fWhen the pin carrying bar is raised it engages the heads of the pins and holds them up. The jacquard strip is perforated and is moved step by step by the intermittent movement of the drum 30 which has teeth 30* engaging marginal openingsin the strip.l Now when the pin carrying bar moves down, any'pin which finds an opening in the paper strip will pass therethrough, but any pin which strikes an im'perforatc. part of the strip will be held up, despite the fact, as just stated, that the pin carrying har has lowered. The pin which passes through the perforation in the paper strip will, of course, move down and this will allow the pull har 27, Figs. 2a and 3. which is resting thereon, to` fall also, and this will bring a shoulder 27' on the pull bar'into adapted to operate against a i position, when weones a `range of an oscillating push plate or bar 39 with the result that,'supposing the push plate is moving towards the left in Fig. 2, the pull bar 27 which has fallen will be pushed leftward and drawing upon the slide 25 will operate the arm 23' which engages its notch 25', Fig. 3, and turn the shaft 23, thus swinging the arm 22 towards the right and moving the plunger carrier rightward to bring the plunger 14 under the proper push bar 13 for operatingthe corresponding yarn feed finger into operative the lifter plate 16 moves upwardly. The train of connections just described will be returned to normal position, as will be hereinafter described. The pull bar which has been operated, as just described, will be elevated to vnormal position by the rise of the pin carrying bar 29 which will elevate the pinfupon which said pull bar rests, and when raised to this normal position, the said pull bar will be out of range of movement of the oscillating bar 39, ready for another action such as just described, when. the pattern strip calls for it. As before stated, there are four pull bars 27V connected with the one slide 25, and the shoulders 27 of these pull bars are inline with eachother, see Fig. 3, but it will be noticed that the oscillating bar 39 has a series of shoulders 39 in stepped relation, and consequently at diiierent distances' from the shoulders 27 of the pull bars 27, so that the slide 25 will be moved different distances, according to which one of the four pull bar is lowered into range of the oscil lating bar 39. rlhe bar 39 oscillates always through the same length of arc, it being mounted on a frame 39 pivoted at 39 to the bracket 34, Fig. 2, and it is operated as will be describedherei'nafter. lf the first one of the'pull bars 27 (comiting from the bottom of Fig. 3) is theone lowered, then' the oscillating bar 39 will move this the maximum distance, because its shoulder 27' stands nearest to the edge of the bar :39;k

This pull bar will therefore cause a full rightward movement of the plunger carrier 15 and the plunger 14 will select the righthand ush bar 13 to throw the right-hand yarn nger down to operative position.

the second pull bar 27 is lowered, there will be some lost motion of the. oscillating bar 34, so that the plunger carrier 15 will`not be moved so far to the right as in. the first instance, and consequently the plunger 14 will select and operate the second yarn finger (counting from the right of the group A, Fig. 3) and so on, as to the other pullbars 27, each in order being operated to a\lesser degree than the preceding one, owing lto the stepped formation 39 in relation to the shoulders 27 of the pull bars.

'lihe train' of mechanism just described .B, Fig. 3.l There is a plunger carrier 15a for this side of the machine with rod l21, lever 22a, and a shaft 23a, which latterV is arranged axially in line with the shaft section 23 above mentioned, and this shaft section 23a is operated through an arm 23b fixed thereon from a slide 25'c1 which is like the slide 25 and has four pull bars 27?' pivoted thereto, to be controlled by certain of the pins 28 and operated severally by the same oscillating b a'r 39 when the pins find openings in the jacquard strip through which to pass when the carrier bar 29 is lowered. f A c lit will be noted that the fingers of group A4 may be selected in any prescribed order desired, the variations in the order of selec? tion dependingv upon the disposition of the holes in the jacquard strip, and this is true also of the vgroup of fingers B and the order of selection of one group may be entirely different from that of the other group.

" ln other words, the .two 'groups are entirely independent of each other in the sense that the order of selection of the fingers of one group may the other group, though. the selection in respect to the two groups is derived from. the same source, i. e., the jacquard strip.

The push plate 39 is operated by a spring 40 in one. direction, this spring being conm nected to the swinging frame. 39, and in the other direction the operation is due to a cam 4l operating against a roll 42 mounted on a slide 33 which bears against an adjustvary indefinitely in respect to ing screw 43 carried by the frame. The eccentric pin 35 of the lever 35 may be turned for adjustment of its Acontacting relation with the slide 33 byfa screw driver, the head of this pin being kerfed, and' when adjusted it is held by a set screw 35". The rocking of the frame 39 is utilized for operating the pattern drum step by step, for which which the pins 28 pass when an opening in purpose the frame carries a pawl 44 to enj tern drum is substantially like that shown im the jacquard strip aligns therewith and when the pin is lowered by the bar 29.

ln order to return the carrier slide 15 to normal position at the left of Fi 2, after being o erated to the right (it eing ob-` served t advancing shoulder 27', but not the ret-urn shoulder, see Fig. 3) the lever 22 has a at the pull bars 27 have. only ther downward extension 22x connected by a rod 46 with an arm 47 on a vertical shaft 48 mounted in the fixed base of the machine and in 'a bearing 49, Fig. 1, and this shaft carries an arm 50 fixed thereto which is in the path of a roller l51 on the shaft 52 forming a part of the rotary'take-up mechanism. This mechanism may be of any suitable type and needs no detailedl description herein, except to say that the revolving frame of -this taken mechanism is shown at 53, and this afi'or s hearings for the shaft 52, one of which is indicated at 54. The shaft is driven by a gear 55 meshing with a circular rack 56 which is supported in xed relation to the frame by arms 57. The shaft 52 carries the clutch 58 which drives the takeup rolls located within the fabric cam 59 and not shown, these rolls being jonrnai'ed in the revolvin take-up frame 53. rIhe roll 51 travelling a out the axis of the machine will hit the arm 50 and through the :rock

' to a lever' 63,

shaft 48 andthe connections just described, the lever 22 will be returned to the normal position shown in Fig. 2, with the selector .plunger 14: at the left of the series of push rods 13 and with the pull bars 27 restored to normal position.

Needle canne.` The machine, bein a two feed type, there are two sets of need e cams, shown in Fig. 5, consisting of 'stitch cams a, a', ralslng cams b, b', and fixed cam pieces 0,'0 and d,

diametrically opposite sides of the machine.

Each of the stitch cams is adjustable automatically to knit tight or slack and for thisI l purpose each is screwed to a post 59 which is normally pressed upwardly by a spring 59 pressing against a` lateral projection 59 of the post, the spring being seated vin a pocket of the cam block, as in ordinary lowerin the stitch cam against the pressure o this spring, the post is notched` at 59 and a crank member or pin 60 enters this notch. This crank pin is journaled in the cam block and on`its outer end it has fixed thereto an arm 60 carrying a screw pin 60 to vbear on a controller ring 61, Fig. 1, which on its edge is /formed with` 'ratchet upper surface is formed with high and low The controller ring is step by a pawl 62 -pivoted ig. 3, which is ivoted at 64 to the base of the machine an is o erated by a slide 65, guided in the frame of t `e machine and havin connected -pivotally thereto at 66 a pull bar 67 which, like the .pull bars before described, is operated leftward, Fig. 3, by the push plate 39. This has two shoulders, like the one whichappears in Fig. 2, so that the push plate 39 will engage one shoulder to advance the pull moved step b troller ring will allowv the arm 60 and there arev two trick wheels e, e, at t teeth 61 and on its vneedle cylinder,

bar leftward to turn the controller ring in the arrow y] direction, Fig. 3, and when the push plate 39 returns to the right it will engage the other shoulder of the pull bar and return it to normal' position to retract the pawl for a fresh operation. `No detent is required to hold the controller ring against overthrow, as the action is not rapid and the friction is su'icient to prevent undue movement. One step movementl will cause a high part of this controller ring 61 to tip the arm 60 up and this, as indicated at the right of Fig. 5, will cause the Hat face` of the pin 60 to engage the lower shoulder of the cam post 59 and lower the stitch cam' for making slackstitches, and when the next step movement of the controller ring takes place. according to the demands of the pattern mechanism, the low part 61b of the conto lower, thus turning the crank pin, so that the spring 59 then becomes effective to raise the cam post 59 and allow the stitch cam to assume position forknitting normally tight.

The control vjust described is exerted at `both feeds simultaneously, because the turningof the controller ring will operate the stitch cams a and a simultaneously, it being understood that there is a crank pin 60 and arm 60 at each of the stitch cams. The knitting of the slackcourse is for making, for instance, the necktie. I

The needle raising cams b, b are pressed normally downward by springs 68 and they are raised by star wheels or cams 69 which ie in the notches 69 of their posts 69, the springs being pocketed in the posts and held in place by overlying plates 69x fixed to the cam box. The star cams are formed in one piece with the hubs 70 of ratchet wheels 70 which are turned step by step, and at such intervals as are prescribed by the pattern mechanism, by pawls`70.

y'The hubs 70 are journaled in `the cam housing or box 71. The pawls 70 are reciprocated once for each revolution of the machine. They are pivotally connected with rocking arms 70x 70, Fig. 2. The arm 70x 72, Figs. -2 and 3, connected with a bell crank 72 pivoted 4to the base of the machine and operated by a slide 72 having a pin` 70x engaging a notch in the bell crank lever.

of the machine and at its inner end it has a .roller 73, dotted lines Figs. 1 and f3,

mounted on a shaft is rocked by a lrodthe neck band portion of vThe slide moves in a guide-way in the base l adaptedto be struck by cams 73', 73, the

former of which moves the slide radially inward, and the latter of which moves the slide radially outward. These cams are carried by the bevel gear 74, dotted lines, Fig. 1, which transmits rotary motion to the it being driven by the bevel y. as to engage 70 on their nent 76 resting on voperate them in a manner gear 74 on the main drive shaft 74, Fig. 1. Not every stroke of .the pawls is elicotive in turning the ratchet wheels 70', but

`only when the pattern mechanism calls for 23a, The pawls 70" 'simply rest on the star.

wheels and when these are turned 'toA present their high points beneath the pawls the latter will be lilted so as toY nnss their ratchets 70 and hence no change in the position of the needle raising cams t, t will take place, whereas when the ratchet wheels 75 are given their next' step movement, the jflat or low sides of thestar cams will corne under the pawl bars 70 'and these will lower so and turn the ratchet Wheels stroke to the right, thus to adjust the nelle raising cams t, b vertically. l

The ratchet wheels75 are turned step by step by pawls 75 pivotally mounted at '751 to slides `76, one 'for each side of the machine, Fig. 3, each ol which has a pullbar one of the pins 28 'to be controlled thereby as to its up or down position in respect to the push plate 39 which is to beptore described.

Each of these pull bars is advanced and retracted by the push plate 39.

The vertical adjustment oi the needle raising cani` cooperates with trick wheels in forming the pattern. i It these earns are in their lower positions those needles which are not raised to clear their latches will pass these cams in tncking position and tuck stitches will be formed on these needles, while those needles whose butts engage the seats in the trick Vwheel will knit, whereas if these raising cams are in their elevated 'positions all needles will knit, because those which pass bI the trick wheels in tucking position will e raised bythe cams Z), bf to clear their latches and hence these needles valso will lrnit.

Auxiliary yarn fingere.

Supplemental yarn 'feed lingers are shown at f and g. 'lhese are pivotallymounted in a bracket 77 and are raised and lowered by push rods 7? and springs, as at 77". The push rods are operated by star cams at 78, Fig. 2, turned by ratchet wheels 78". Pawls 78" turn the ratchet wheels and tliesepawls are worked by levers 79 loosely mounted 'on the shafto23 and operated by slides 79', 7 9, which are operated by the pull bars 80, 80', oi #the pattern mechanism. These fingers are adapted to feed only those needles which are raised to knitting position by .the trick wheels.` They will not feed those positions at needles which leave the trick wheel `in tucking position and hence variations in the pattern can be produced by throwing these lingers into and out of work. These auxiliary fingersfwhen lowered to feeding posetion, lie just below the elevated throat l0 of the ring 11, see. diagram Fig. 5, so that they feed the yarn over 'the edge of this throat to the needles' which are fully elevated by the trick wheel. This feeding position oi the auxiliary yarn nnger is indicated at f, Fig. 5, and its raised position at f. The raised position of the other auxiliary yarn linger is indicated atg. Its feeding position is'at the same lowlevel of the finger at f. This diierence in the ele. vatedpositions of these two lingers is for Vthe purpose of preventing the two yarns from winding or twisting together-'clear up 'to the yarn fingers' from the center of the `fabric which, if it happened, would prehe y/arns from being fed to the needles ing a separated position to the two auxiliary yarn fingers when raised equal to thel distance between f and g, the two auxiliary yarns are kept apart, so that each may be lowered to feeding position individually without interference by the other yarn. The feeding position oi 'the main yarn fingers is indicated at A and their elevated A. They lie, when lowered to feeding position, in the throat space 10. The height of the needle wave resulting lfrom the trick wheel seatsl e liitin certain of the needles, `is indicated at c2, an the low wave line at this point due to the needle butts passing through the cuts e in the trick wheel periphery, is indicated at e". The wave line passing the main yarn fingers may be low, as indicated at b, if cam b is down, or it maybe higher up, it cam b is raised, but in either case, the yarn will be taken by all of the needles at this oint. `The feed Inouth for the other group ofp` lfingers B isy shown at 10.` A 'guide finger o projects up from the throat l to propand direct the idle yarns 'from the fingers,v

which are raised, towards the machines axis, where these idle yarns are twisted into a rope or cord form. This action is also assisted by a guard p2 consisting of a wire attached to bar and inclining downwardly and inwardly. When a yarn nger yarn me l

against the inclined y twisted together,

raised, the point where this yarn is tied guards the yarns will be kept separate for 'a considerable length thereof extending from the yarn fingers, and thus each may be lowered individually without interference by the other yarns, .it being observed that the point where the twisting begins is below the level of the feeding positions of the yarn fingers. Suppose in Fig. 3 that one of the yarn feed'fingers is lifted out of work. The end which is tied into the fabric will travel in the across the interior of the needle cylinder,

'but it will be depressed at its center by sliding down the inclines of the plates p and bar p2, and as the rotary movement continues and additional idle yarn is drawn off, it will twisttogether at y.the center of the cylinder.

I provide means for counting the number of neckties knit. This consists of counting mechanism C, Fig. 2, operated by a rod 81, Fig. 2, from a lever 82, the lower arm of which is operated by a slide 88, Fig. 3, having a pull bar 84 controlled by the pattern mechanism before described.

Reverting to the yarn linger selecting mechanism and particularly to the action of the plunger 14 and the return arm 50, it will be'observed that this return arm, when struck by the roller 51, will return the plunger carrier 15 towards the left, Fig. 2, until the plunger 14 gets under the cam inoline 14'. of the bracket. Further movement of the plunger carrier leftward will be due to the rise of the plunger under the action of the lifter plate 16, which will force `the plunger up into contact with the said cam incline 14b and thus shift it further leftward. This will have the effect of throwing the return arm 50 further out, so that it will be entirely outside the path of movement of the rollery 51, so as not to be hit idly thereby. This action just described will set the parts at the pattern mechanism in normal position so that at the proper time vthe plunger carrier will be moved towards the right, the plunger 14 will be lowered, together with the outer end of the lifting plate 16, so that vnow be inthe path of cam 19, and the return arm 50 will be set inward to be struck by the roller 51 when this comes around to restore the mechanism partway to normal position, this taking place after the lifting'plate 16 has operated to raise the plunger 14 and vchange the yarn fingers.

i The machine is provided with so-called arrow direction and extend "ingit, a reciprocatory pawl for sinkers or web holders of substantially known form and operation.
