KNlTTING MACHINE.

Kenneth Howie and Charles C. Krieble, Norristown, Pa., assignors to Wildman Mfg. 00., 1 Norristown; Pa., a corporation of Pennsylvania Application October 18, 1941, Serial No. 415,654 44 Claims. (01. 66-96) This invention relates to knitting machines of the full fashioned type, and. more particularly to mechanism therefor for turning the weltof a ladys full fashioned hose kniton such a machine. With the mechanism of this invention the yarn of the initial course of the fabric is automatically caught upon points, and these points subsequently automatically deliver the loops -of that initial courseto the needles in order to close the welt.

Furthermore, after. the loops of. the initial course of the fabric have been delivered to the needles, the points are automaticallyjremoved to an inactive position so that knitting of the remainder of the fabric will proceed without interruption. v V v i As a further feature of the invention; a welt rod isautomatically dropped into place sometime before thewelt is closed; and since the fabric.

take-up belts are connected to this welt'rod, the operation of the machine is not interrupted.

As a further feature of the invention, the loops of another course of the fabric become placed upon the points during the welt turning operation, and they also are delivered to the needles so that a 'strongjunction of thefabric results.

The invention also includes a welt point of a novel construction for carrying out the weltturningoperation.

Other features of the hereinafter appear. v

. Because of the features of the invention resulting ina completely automatic turning of the welt, manual intervention is not necessary after the machine has been set in operation to lay the initial yarn. a g V The mechanism of the invention is here shown applied to a single-head, full fashioned knitting machine .of the type disclosed in Howie Patent No. 1,982,991,.grantedon December 4, 1934, and reference may be had to that patent, for details of the knitting machine not illustrated in. the

Referring first to Figs. 13, 13a, and 14 in particular, the welt point employed to carryout the invention is formed at itslower end with a curved portion 52, the con'cavcdside or which faces toward the beardof the needle when the point is on the beard side of the needle. Into thi's-concaved side-isformd a notch which will provide a shoulder 5"! to retain "a yarn upon the point. The extreme lower end Sq-of the point is'reduced as appears in Fig. 14 so that it will more. readily enter-aloop of the fabric, as will later appear Upwardly from the shoulder 54,

and on the same side of the point, is an eye 53 to receive the beard of the knitting needle 55-.

- Theshoulder 5i preferably is of less width than the stem therebehind, so that the stem serves as a shield to the =-shoulder. This shielding effect of the stem withrespeot-to the narrower shoulder will serve to insure transfer'of th'eloops from the points of the-needles without the yarn catching upon the-shoulder. To-obtain this shielding relation, the portion of the point 50-below the notch providing the shoulder 51 may be thinned or flattened, as appears in Figs..13 and 13a.

The curvature oi-the lower end of the point has several advantages. It removesthe shoulder 51 of the point away from the needle beard when the heard is in the eye 5301? the point, and-at the same time enables the lower end 54 of the .point to enter an eye in the needle below the heard as shown in Fig. 10. This curvature of the lower end of the point also will cau'seitto retain a yarn which may not have become caught upon the shoulder 51, and additionally serves to facilitate movement of the lower end of the point between the'needles and sinkers. The thinning, or flattelling of the lower portion of the point 50 further facilitates this movement of. the lower end of the'point between the needles and sinkers.

The position of the parts at the start of knitting a fabric is shown in Figs. 17, 18, and 19. Thisis the position which the parts assume after the previously knit fabric has been dropped from the needles. The succeeding steps for accomplishing turning of the welt of a new fabric are shown in Figs. 1 to 12, inclusive. As shown in Fig. 17, the points 50 are initially located on the beardless sideof the needles 55, and at quite a distance from them. There is a point for every needle, and the points are in line with the needles and'not in line with the spaces between the needles. This is the position of the points during the knitting of the part of the previous fabric after its welt has been fully turned.

In moving to the position shown in Fig. l to start anew fabric, the points 50 have been moved toward the needles from the position of Fig. 17, and have also been elevated slightly. At the end of this time, the needles are at their elevated position at which the yarn is laid upon them. and the yarn carrier 5'! is advancing lengthwise of the needle row to lay the first yarn, As also shown in Fig. l, the sinkers 56 are being advanced in order to sink the yarn about alternate needles.

To reach the position of Fig. 2, the dividers have been first advanced and the needles have then'been moved downwardly so that the tops of the needles are at the throats of thesinkers and dividers. Also the needles have been moved rearwardly so as to bring the beards of the needles against the presser bet-r58. In the position of Fig. 2, the points 50 have been-moved to the beard or operating side of the needles. To result in the relationship shown in Fig. 2, it is not necessary that the points 50 be raised in moving from the position of Fig. 1 in order to position them on the beard side of the needles, because the needles have been lowered to such a position that the mere rearward'movement of the points 50 will bring them to the beard sides of the needles points 50 have been lowered so that their shoulders 5| are below the yarn. The lower ends of the points-5'0 are now between the knockover bits 59.

InjFig. 4,- the needles have'been moved still further downwardly so that the tops of them are below the upper surface of the knockover bits 59. This movement brings the yarn downwardly upon the tops of the knockover bits. At this-time, the points 50 are shog'ged ina direction lengthwise of the needle rowa half needle space so that they will be out of alignmentwith the needles and will be m line with the spaces between the needles. The needles are then moved rearwa'rdly toward the throat of the knockover bits 59. and because of the disalignment of the points'and'needles, the needles are caused to pass by the points Without collision occurring between them. In Fig. 4, the points are shown in the position of this movement in which they are alongside of the needles. The thinning out of the lowerends of the points as shown in Fig. 13 is important inorder'to permit this passage of the needles past the points even though they are located between the knockover bits at this time.

After the points are on the beardless side of the needle row, they are-shogged back -into alignment with the needles. As a result-ofthe movement of the needles between the points, the

sinker and dividerloops aregcaught -upontthe shoulders [of the points-50. The points 50 serve ma herefo ,prov In Fig 5, a,portion of the welt. shown as havingbeen knit. During this knitting-of the welt, the points 50; are moved away ;from;th e needles under the; influence of the usual fabric take-up meansiin order to take up the fabric as itais knith vDuring-the movement of the points 50 away from t the needles while the welt is being knitted, the-points 50 remain at the same level. InFig. 6,the;kn it fabricisthe same as that of F ig. 5, but the welt rod 110, has been dropped in place. Also, the points 50; ha ve heenmoved slightlytoward the needlesand have been elevated in order to fold the fabric over the welt 9 i9 the ab i tak r nnt e rod urges the rod away fromthe Il881185;.

1 As a result of thisf lding of; the "fabric over the. welt rod, the loops of two courses arenow ulionthe points, andith i qonstitutqs an unpon tant feature of the invention. Thernanner in which .the loops of two. courses .are positioned ""n each point is shownin. the enlarged detail views ofFigs.5dand5b. I In order toreadily accomplishthis location of the loops in two coursesupon the Welt points 50, it is desirable that the first course 62 be lrnit as a loose-stitch, thatthelsecond course '63 be knit as a tight stitch, and that the third. course 64 which islknit Bela loose stitch. .The remainder :of the welt fabric maybe of auniforrn tightstitch. As

shown inFig. 5a, atfth start fthe folding of I the fabric pverthe welt r od, the yarn will be brought against the lower rear. portion: of the pointsj In this position shown i lifig,v 5a, the loose course 64 close to thelowermost end 54 of the point fsot Further fplding over of th fabric will cause'the loose course 64 tobe brought under the lowermost tip oi the welt point 50, and will then cause the tip 5,4 to enter the loose course 64 as shown in Fig. 5b;. when the loose course 64. is then-urged upwardly so as to lie close 't'othe loose course tzfalready-upon the welt point, these loops of two courses of the fabric will be positioned one abovetheother uponthe welt knitting of the fabric.

ditional tension is applied to the. take-up means during the knitting of the rabric when the welt rod is folded in the fabric, inorder to compensate for the frictional drag of the fabric over the rod and for thetehsion in the fabric between'the Welt rod and the points. From the position-of Fig. 6a, the points are moved toward the needles to close the weltfthe add ional take-up tension being releasedat thi's time.

IInFig. '7, the needles garetmoving through their regular needle narrowing, motion, and have moved downwardly soj thatftheir upper ends are approximately at the level of the sinker throat. The welt points 50 have been movedto and over the tops of-the needles so that they .now occupy, a position tothe rear of the. needles w. In-prder t eeqbifit lqt i bnlshowa F isne es- In Fig. 8, the needles havemoved downwardly fromthe position of Fig. 7,1 and also have-moved towards the presser bar 58.; Thenwelt points50 have moved downwardly on thebeard side ofsthe needle, and have carried the fabric which is upon the points downwardly below the sinkers. This fabric now rest upon the tops of the .knockover itste. v i

. ,In B 9, the welt omtst'ohav moved down ,wardly so: that their eyes "53 tare 'opposite the beards ofthe needles This downward movement of the 'weltpoints hasv caused the fabric to be pushed upwardly along the welt points by the knockover bits 59 so asgto lie'above. the1eye- 53 of the points. In Fig. 9, the sinkers have. been rnoyed forwardly from their position i118,

so that -theypVerIie' the needles and also overlie theta-brie. v I 1 l ,In Fig. 10, the needles have progressed through their narrowing motion and have moved ina direction toward the .presse'r bar. 58; Thismove ment-has brought the beard'of each needle55 into the eye 53- of a weltpoint 50; :1 Also; the low-.-: errnost tip 54 of each we1t .point:50. hasente'red thegeyeilifl in each-needle below the, beardfi':

In Fignll, the welt points-andthe needles'have been .m0v ed upwardly in unison with each other. The over-lying sinkers 56 serve .to prevehtupward movement of the fab-ricwiththe points and'nee dles, sothat the'yarn is stripped downwardlydoif of ;the points. Theupward movementaof the needles causes, them to enter the loopsBZ and i upon the points -50, and in this manner. transferv wardly to a position above the tops of the needles and: from this position .the points may.m6ve away from the'presser edge to the position shown. in Fig. 17; which the points :normally o'ccupy; As has been stated, the points remain in this po-- sition shown in'Fig.v l'lrduring thesubsequent From the position shown in Fig. 1-2, the needles will be moved upwardly to theirposition shown in Fig. 1'; so that they may receive .a newfiyarn. which is to be laid down and which will be drawn through the loose loops 62 and 64,: and also through the loops shown upon the needles in Fig; 6a. In this manner, thewelt is completely closed, asshown in Fig; .16, and the loops 62 'and lilwill be joined to the fabric.. Thereafter the needles will be caused to, successively pass:.through*their regulanknitting motion, so that the portion of the fabric following the welt will -be'knit; and the fabricshown in Fig. 15 will result. To support thewelt points-50,- they arelcarried' in awelt bar 65 which includes a front clamping I The welt bar, 65. ispermanentlyflattached at its ends to side arms 61 arid'68. The. other'ends of the side armstlland 68 fromtheir points of attachment to the welt bar 65 are pivotally connected to upright arms 69 and 10,. respectively. The side arm 51 is pivotally connect-- ed to the upright arm ,Btlby means ofa .boltfH;

which passes freely through. a bearing end .por-y tion of the arm 69 and is threaded in the: arm

'6 A like bolt 12 serves to pivot-all oonnectto-' gether the side arm 68 and the 'uprightarm 10L Thelower. ends of the upright arms 69 andim are pinned to a rock shaft-14;,.- Rock shaft .114 is.

rotatably mounted 'in bearing's 'in the lower ends of hangers I5 and I6. The upper- 'ends ofthe hangers and I5 are permanentlysecured to a trough-shaped member 11. ,The opposite ends of this: trough shaped member 'I'I are rigidly secured to the side frames I8 and 19 of the-machine framework, so that the trough-shaped member 11 is a fixed part of the machine. V

The. central portions of the arms 89 and I8--are bent outwardly away from the machine, so that they lie. beyondthe ends of the trough-shaped member TI, and also outsideof the side frames 18 and 19.. This formation of the arms 69' and I8 permits a greater arc of movement of the armssince. the trough-shaped-Inemb'er I1 and side frames I8 and- I9 do'not limit th'eir movement.

In order to-acljustthe upright arms 69 and I8 withrespect'to rockshaft I4, their lower ends are split, as best shown in Fig. 20, to provide a thin-portion 8I and a rigid portion 82. The thin portion-8| is integral: withthe arm IIl, and because it'is thin and slightly flexible, the angular position of. the arm I8 about the shaft I Imay be changed. The rigid portion 82 should be of such strength: thatits relationship with respect to the rock shaft "will remain relatively fixed. A -sleeve=83 is threaded into the upper end ofthe rigidportion 82 and bears against the arm- 18 so as to: force the arm 18 away from the rigid portion 82. Passing through the sleeve 83 is a boltzfl: which is threaded into the arm I8. Bolt is not threaded into sleeve 83, but the head of bolt 84 bearsagainst the outer face of sleeve so that by screwing inwardly this belt 84, the arm III will be drawn toward the rigid portion 82. By adjusting the sleeve 83 and the bolt'84. therefore, the upright arm I8 may be adjusted withrespect to the rigid portion 82. In thismanner, arms and 18' may be fixed with respect to shaft 14. I

- In order 'to-turn the rock shaft I4, it has affixed-thereto a driving arm 85' which carries a rollerz85 at itsfree end, andthis roller bears upon acam'8'l secured to a cam shaft88; Rotation of thecam shaft 88iwill. cause the arms 69 and I8 to move back and forthin" unison with each other; 'The conformation .of the periphery of cam 87 wilh be explained in connection with the general operation: of the machine.

. 'Iloswing the arm- 85 toward the cam 8l-so that the roller 86 will follow the cam '81, a torsion spring 89(Fig. 18) is located uponthe shaft't'll'. One end of this torsion spring 89 is embedded in a recessin' the adjacentface-of the hanger: IG;: and the other endof the spring is embedded: in a.- recess in ancollar 98-which may be affixed to: the rock shaft I4. By rotating the collanQIl about the shaft 14', and fixing it in position, the force exerted by the spring 89 to cause the roller 86 to bear against'thecam 81 may be increased or decreased.- The spring 89" need not be'strong, since'it is not relied upon to applytension: to take up the welt as it is knit.

Themam shaft 88" is rotatably mounted inbearings: inthehangers I5 and 18. In order to rotate the cam. shaft 88; it has pinned-thereto a ratchet wheel- 9!. having fivenotches in the periphery thereof. The notches Q-Ia, 92b,- 92c, and 92c-are a quarter turn apart, and notch MCI is midwaybetwee'n notches 92c and 92c seeFi'gs. 21",

22, and 40). Rotatably mounted upon the shaft 88; and atone side of tl 'ie ratchet' wheelw t, is a pawllcarrier'93t 'Thispawlcarrier 93'is retained against the ratchet wheel 9I by a collar 9W secared to the shaft =88; To'theouter end of-the' pawl carrier 93 is pivotally attached a pawl 85, and a=-spring- 96 urgesthispawl toward the periphery of the ratchet wheel 9| so that it will engage the notches therein. 7

In-order to operate the pawl carrier 93 and therebyrotate the ratchet wheel 9|, a link-911s pivotally connected to the pawl carrier and is also pivotally connected to one arm'of a lever 98(Fig. 17). The lever 98-is pivotallymounted upon a shaft 99: This shaft 99-occuples the positionof the shaft appearing in Fig. 6-of the'aforementioned Howie Patent No. 1,982,991, towhich the-cam- I8 is afiixed. In order to accommodate thelever 98; the shaft 99 must be elongated beyond its length shown in Patent No. 1,982,991. The, otherarm of the-lever 98 has'rotatably attached thereto a'roller I8I which bears upon a cam I88 securedto the main cam shaft a of the knitting machine; This main cam shaft a is the same as that appearing at a in the knitting machine illustrated in Howie Patent No. 1,982,991.

A spring I82=causes roller -I8=I to follow cam' I88, the lower end-of this spring being connected to the machine framework. From Figs. 17 and'21 it will be apparent that the thrust of pawl 95 which actuallyserves to rotate shaft 88 is due to the pull exerted by spring I82 and is not duev to'a force exerted by the cam I88. The cam I88 merely lifts roller I8I so that the spring I82 can become-active to give the pawl 95- its driving thrust.

During the operationof the machine; the pawl carrier 93 oscillates back and forth repeatedly, and pawlwould therefore tend to constantly rotatethe ratchet wheel 9! ifmeans were not provided to interrupt its operation. To determine when the pawl 95 shall engage a notch in wheel- 9'I-, a shield-184 is pivotally mounted upon a bolt I85, which is threaded into alug I86 projecting from the side of the-hanger'lfi; Thisshield I84 lies close to the side of the ratchet wheel M, and its outer surface is curved to conform generally to the circular periphery of the ratchet wheel SI. The pawl 95 is wide enough. at the notch engagingportion thereof to bear upon the shield-I84; and the pawl 95 will therefore ride back and forth upon the-shieldand be prevented from engaging into any notches inwheel 9I when the shield is out.

To move the shield inwardly toward the shaft 88 and thereby permit the pawl 95 to engage a notch in wheel 9|, an arm- I '8'I*of the shield is pivotally attached to alink I88." The lower end of linlr' I88 is pivotally connected to a lever I89 (Fig. 17') which at one end is pivoted to a fixed partof the machine. The free end of lever I89 bears upon the pattern drum A which is shown in- Howie Patent No. 1,982,991. Buttons I-I8'an'd III-affixed to the pattern drum A will lift the lever I89 and thereby; serve to swing'the shield I8 4 inwardly away from the periphery of the ratchet wheel 9' I to thereby permit the pawl 95 to enter-one of the notches therein. Thus; although" the pawl 95 is constantly-oscillated during the operation of the machine, it willaot' upon:

button necessarily swings the shield I84 further toward theshaft 88 than does a low button. Also, from Fig. 40 it will be observed that notches- 82a; 9'2c, and 92d are located further-radlallyoutward- From Fig. 17 it wlll'be observed that buttons- II8= are low, whereas button III is high. A high 1y from thecenter of ratchet wheel 9 I than are notches 92b and 92a; A low button I IIl-willmovethe shield I84 inwardly only far enough top'ermit the pawl 95 to engageone of the outer notches 92a, 920, or 82d, it being necessary for a high buttonI I I to act in orderto swing the shield inwardly sufliciently far'to' permit the pawl 95 to engage one of the inner notches 92b or 92c.

This relation between the high and low buttons on pattern drum A, and the inner andouter notches in ratchet wheel 8|, make it unnecessary to immediately rotate the pattern drum to remove a button from beneath the lever I89 after that button has served to initiate rotation of shaft 88. For example, it may be assumed that ratchet wheel 8| is in position for the pawl 85 toengage in notch 9211, !but this engagement is prevented because no button on the drum'Ais beneath lever I89. To cause the pawl to engagejthe notch 920., a low button III) is brought beneath lever I88, and the ratchet wheel BI isthereby turned a quarter turn. The ratchet wheel is now'inposi tion for its notch 92!) to be engagedlby the pawl 95, but the shield I84 prevents such engagement asit'is not'inwardly sufficiently far to uncover the notch 9217. I

The shaft 88, theref re,-'wi1l not be turned even though the button IIII remains under the lever I09 and the drumA is not turned, When it is desired that the' pawl Bil-engage the notch 92?),

a high button I II is brought into action tocause the shield I84 to move inwardly sufficiently far to uncover the notch. Thus, due to the-relation between the high and lowlpattern buttons, and the inner and outer ratchet wheel notches. repeated operation of the-shaft'88 is prevented, even though a low button remains under lever I88."-

It is desirable that the cam shaft 88 be positively retained in the position to whiclri't is moved after each driving actionof the" pawl 85, and for this purpose, an index wheel In (Fig. 22) is pinned to the cam shaft 88. A detent II3 is slidably positioned in lugs H4, H5 projecting from the hanger 15, and a spring I I6 urges the detent II3 against the periphery of the index wheel H2. The periphery of the index wheel H2 is formed with notches into which the detent I I3 Will engage to retain the cam shaft against accidental rotation.

"To guide the side arms 61 and 68in their for-.

ward or'backward movementunder the action of cam 81, guide arms I22, I23 "are'provided. At their upper ends, the arms I22, I23 are formed with elongated projecting portionsI24, I25,re-

spectively, and with overhanging portions I26, I21, respectively. A pin II8 projecting from the side of arm 81 rides upon the upwardly facing surface of the extension I24, and may enter into the recess between this surface and the overhanging portion I26 (Figs. 24, 25). In like man her, a pin H9 of arm 68 (Fig. 17) will ride upon the upwardly facing surface of the forward extension" I25 of arm I23, and may recede so as to enter between this surface and the overhanging portion I21. Flanges I28 and I2I at the ends of pins- I I8 and H9, respectively (Fig. 25), bear against inner opposing faces of guide arms I22 and I23 to fix the endwise position of the Welt bar 65. I

- The guide armsl22 and I23 are carried by a shaft 1 28 which is 'rotatably mounted in bearings in the hangers 15, 16.

The arm I23 is loose upon the shaft I28, and in ,order to connect it tov the shaft I28 so that it will be moved by the shaft, aconnectingarm I38 (Figs. 18, 26)' is pinnedto the shaft I28 adjacent to the arm I23. A bolt I28 passes through a log portion I3I oflthe armfI23, and is bolted into the connecting arm I38 in order to firmly hold them together. The opening inthe lug portion' I3I- of the arm I23, through which the bolt passes is preferably of arcuateshape about the axis of shaft I28 in order to permit a limited angular adjustment between the arm I23 and the connecting arm I38. j

a To facilitate adjustmentyof the angular relationship between the guide arm I23 and the con necting arm I38, a bolt I33 is threaded into an offset portion I34 of; the connecting arm I30, and bears upon-the lug'portion I3I of the armI23. A lock nut I 32 upon bolt I33 holds it against rotation, By loosening lock nut I32 and bolt I29, and then screwing the bolt I33 inwardly orfout wardly,'the'arm I23 can "readily be'broughtto its desired point of adjustment.

23) to receive shaft I28,but thearm I22 is'fnot fixed directly to the shaft I28, butins'tead is [attached by means of 'a'bolt13'6'to'an actuating arm I31 which is pinned at I35i (Fig. 18) to the shaft I28; The passage 'of the shaft I28 through the arm I22 and the clamping action of 'the'bolt I38 serve to positivelyfix' 'the'ang'ularposition 0f the arm I22 with res ect tdthe shaft 'I28lf' The actuating arm I31 extendsfdownw'ardly to aposition-for'its'lower end to'be b rne upon by a lifting cam I38"aflixed to the camshaft 83.- In order to provide an adiustment'betweenthe cam I38 and the lower end of the arm I31, a fi'e xif ble shoe I38 is afiixed by means of a screw/I48 the Welt bar as which as been describedf theshaft I28 is capable'of a'lii'nit'edendwise motion through "its :bearihgs'in the hangers 15Ianfd 16; A spring I45(Fig'. 18) 'is'located upon-the shaft I28 adjacent the hanger 15; and'one end or the spring bears upon 'the hanger"15,'""The other end of the spring hears upon a collar I 46 lwhichis mixed to the shaft I28 and the spring I45 therefore acts to -'urge the shaft I28 in a righthanddirection as the machine is viewedin Fig." 18. The endwise movement of "shaft I28 under theinfiuenc'e of spring I45 iS limited by a stophut I41 (F i Y'2 8) which isth'rea'ded upon acollar I49'afiiXedt'o the shaft I28 inside of the hanger 16(By rotating the nut I41 upon the collar I49, the endwise movement of'shaft' I28 "may be adjusted, and this may be fixed by tightening the nut I48 which serves asalock'nut. '1

To impart a leftwise movement"tofthe shaft I28, it isact'ed upon" by a leverfIISfwhich is pivoted at I52 to alug 'l53' projectingffrom the hanger 16. The u er end of lev er I5I carries a bolt I54 which is axially in line withfshaft I28. This bolt I54may'be turnedin order" to vary its position within the uppei 'enq of lever I5I and thereby vary the extent of 'the axial movement which will beimparted were shaft I 28 in a leftwise direction. The lower end of lever I5I is adapted to be engaged by a button I55 (Fig. 29) aflixed tothe side of the cam 81. To the lower end ofthe lever II may be afiixed a shoe I56 to receive the thrust of the button I55 during the rotation of the cam 81. A spring I urges shoe I56 away from the face of cam 81.

The endwise movement of shaft I28 under the action of the button I will cause the side arms I22, I23, to also move in a direction parallel with the needle row. Because the welt bar- 65 is-held in fixed position between the arms I22, I23 by means of the flanges I20, I2I of the pins II8, I I9, respectively, which bear upon the inner faces ofthe upper portions of the arms I22, I23, when the arms I 22, I23 are moved with the endwise movement of the shaft I28, the welt bar 65 will be moved correspondingly.

The pins I I8 and I I9 by bearing upon the side arms I22 and I23 serve to hold upwardly the welt bar 65 when the welt bar65 is in a rearward position toward the needles. In order to hold the welt bar 65 upwardly when it is in a position spaced forwardly from the needles, as in'Fig. 17, the arms 61 and 68 are provided with pins I64 and I65, respectively, which ride on rail plates I60, I6I. Thepin I65 is carried-by a bracket I66 (-Fig. 19) which is afiixed to 2. lug I81 projecting from the *outer side of the arm 68. The pin I64 is supported in a like manner fromthearm 61 by bracket I51 and lug I58 (Figs. 30- and 32).

The rail plates-I66, I6I are affixed to the'outer sides of rail bars I62, I63, respectively. The rail bars I62, I63 are afiixed tothe top of the trough member 11 and their rearward'ends'extend close to the needle row and their forward ends extend 1 close to the fabric take-up means at the front of the machine. The upper surfaces of the rail bars-I62, I63 serve to support the welt rod which is ordinarily employed in connection with the turning of the welt of a full fashioned hose. The upright portions of these side'rails may be offset in a direction away from each other above the rail bars I62, I63, by means of a rib along their lower edges as appears at I59 in Fig. 30.

As has been noted, when theweltbar-65 is at a distance away from the needles, it and the arms 61 and- 68 are supported by the pins I64 and I65 which ride onthe guide plates I and I6I, respectively. When the welt bar is toward the needles, the pins I18 and H8 ride upon the upper surfacesofthe arm portions I24 and I25, respectively. to support the welt bar. This arrangement is of importance because it leaves a gap I44 (Fig. 1'1) between the forward ends of the arm portions I24, I25, and'the rearward portions ofthe guide plates I60, -I6I through which the operator may pass the yarns which are handled by the machine. Bypassing theseyarns throughthese gaps, they may be attached in the usual manner to clamping means (not shown) which areordinarily attached to the trough member 11. It will be understood, however, that if desired, the arin extensions I24, I25 could extend forwardly sufliciently far toward the fabric take-up means so'that the guide plates I60, I6I could be eliminated, but this latter'arrangement would lack the convenience of the structure which is illustrated.

The welt rod I10 initially occupies a position upon the top of the welt bar (Figs. 33, 34). It rests against stop pins I13 projecting from uprights I14 secured to the rear of the welt bar 65, as shown in detail in Fig. 34.

,Slightly inwardly from the ends of the welt rod I10 are aflixed plates I16. The distance between the plates I16 is slightly greater than the length of welt bar 65 so that the plates I16 will not grip the ends of the welt bar. To the lower ends of the plates I18 are afiixed pins I11 having therein near their ends grooves I18. These grooves I18 will receive the hooks I19 of the belts I80, which are attached to the reel I 8I of the take-up mechanism.

At the start of a new fabric, the welt rod I10 will be in its position upon the top of welt bar 65, and the hooks I18 will be attached to the pins I11. To resist the pull of the take-up belts, lugs I82 are provided upon a lower extension of the side arms 61 and 68, and the lower ends of the plates I16 bear against them (Fig. 35). The pull of the take-up belts tends to turn the plates I16 about the lugs I82 as a fulcrum, and move the rod I10 away from stop pins I13 (Fig. 34), inasmuch as the pull is applied to the pins I11 which are below the lugs I82.

A pusher bar I83 serves to resist this tendency of the take-up belts to dislodge the welt rod I10 from its position on the top of the welt bar 65, and also serves to dislodge the welt rod I10 at the desired time. For the pusher bar I83 to act to retain the welt rod upon the top of the welt bar, its end is formed with a hook I90 (Fig. 33) to positively engage the welt rod I10.

This pusher element I83 is pivotally connected to the upper arm of a bell crank lever I84 which is pivotable about the pin I 64 by which it is supported (Figs. 30 and 32). A roller I85 is pivotally connected to the other arm of the bell crank lever I84, and this roller I85 will be acted upon by an upward movement of T-shaped trip member I86. When the trip member I86 is urged upwardly so as to strike the roller I85, the pusher bar I83 is caused to move toward the rod I10 and dislodge it from the top of the Welt bar 65. The rod I10 then falls downwardly until the projecting ends I15of rod I10 strike the upper sur face of the guide rails I62, I63. These ends I15 move along upon this upper surface during the subsequent knitting of the fabric, under the pull of the take-upbelts I as shown in Fig. 36.

When the welt rod I10 is dislodged, it moves downwardly past the face of the welt bar 55 and points 50 and upon the fabric. To prevent the welt rod from strikin the points 50 during this downward movement, guards I89 are carried by the welt bar 65 at the endsof the point row. These guards I89 are 'held' in the welt bar in the same manner that the points themselves are held, and are about as thin as the points. However, the guards are wider and slightly longer than the points, as'shown in Figs. 33 and 34, so that the welt rod will ride upon the guards and cannot strike the points. If the points 58 were to strike the welt rod I10, nicks might be made in the rod which would catch in the fabric.

The pusher bar I83 is urged to a retracted position by means of a spring I 81 which extends from it to a pin on the side of arm 61. A pin I88 (Fig. 30) carried by bracket I51 serves as a stop to limit the rearward movement of the pusher bar I83 under the influence of the spring I81. Also, the spring I81 exerts a downward pull upon the pusher bar I83, so that its hooked end will bear more firmly upon the welt rod I10, as shown in Fig. 33.

To prevent the welt rod I10 from falling down upon the fabric in the event that it is inadvertently prematurely dislodged, guards I68 are attached at the ends of the picot rod I68 by screws-which pass through holes I1I in the spect to the needles. and transferof the loops from the points .to the needles will be assured. Since the narrowing frame will control the motion of the welt points at this time, it is not necessary for cam I38 to exert any control and for this reason there should be nocontact between cam I38 and the shoe follower I42, as shown in Fig-24, at this time.

Inithe operation of the machine, the parts initially occupy the positionshown in Figs. 17, l8, l9, and 23. At this time, the roller 86 is at the position marked on cam 81 in. Fig. 38, and the nose. I42 is at theposition marked0 on cam I38. Also at this time a high button III on pattern drum A is beneath lever I09,-and has moved shield I04 inwardly so that the pawl 95. may engage notch 92b. Rotation of the main cam shaft will therefore cause, through the action of the pawl 95; rotation of the camshaft 88.

-From-the position shown in Figs. 1'7, 18, 19, and 23,-the main cam shaft will make one complete rotation, and this will cause the auxiliary cam shaft 88 to make a quarter turn. Such a quarter turn movement of cam shaft 88 will bring the point marked a: on cam 81 to the roller 86, so that the points 50 will have been'moved part way toward the needles. The point marked :0 on cam I38 will have been brought to the shoe I42, and thiswill cause a slight lifting movement of the side arms I22, I23. During this first complete rotation of the main cam shaft, the needles will have passed through a knitting stroke, but no knitting will have been performed because no yarnwill have been laid during this time.

Theauxiliary cam shaft 88 will be rotated by the next rotation of the main cam shaft, due to a lowbutton IIO being under lever I09. The pawl 95 will engage notch 920 at this time to drive the auxiliary cam shaft.

.During the first portion of this next full rotation of the main cam shaft, a yarn will be laid down against the needles, and the sinkers will have advanced to the rear of the movement of the yarn carrier guide to sink the yarn. At the end'of this time, the auxiliary shaft 88 will have been moved so that the point I on the periphery thereof will be brought to the roller 86, thus moving the points 50 closer to the needles. The point I on cam I38 will now bear on the nose I42. In continuing the rotation of the main cam shaft in this second full rotation, the dividers will-be moved outwardly. At the end of this time, the needles will move to the press bar 58. Also, the auxiliary cam shaft 88 will have turned so that the point 2 on cam 81 willbear on roller 88 and will have caused the points 50 to be brought to the beard side of the needles, as shown in Fig. 2. This rotation of the auxiliary cam shaft 88 will also have brought the point 2 on the periphery of cam I38 to the nose I42, but inasmuch as the portion of the periphery between points I and 2' is'approximately arcuate, the side arms I22 and I23 will remain at the sam height.

Only a portion of the second quarter turn of auxiliary cam shaft 88 under the influence of pawl 95 will have been accomplished by this time. During the rotation of the main cam shaft in continuing its second full rotation, the needles will be brought to'the yarn drop off position shown in Fig. 3, and the auxiliary cam shaft 88 will have been moved a slight arcuate distance so that thepoint 3 on the cam 81 is opposite roller 86. Since the point 3 is further inwardly than the point 2 on cam B'Lth points 50 will have been. moved forwardly toward th needles, as

show n i 3. At this same time, the point marked 3.on the cam 138 will be at the nose I42,-.and this will have caused the points 50 to have dropped to the position shOWn in Fig. 3.

i Further movement of the main cam shaft in continuing through its second full rotation will move the needle to the-position shown in Fig. 4, in which the yarn is brought below the tops of the knockover bits 59. This movement of the main cam shaft will have moved the auxiliary cam shaft 88 so that the point 4 on the periphery of cam 87 is at the roller 86 to thereby position the point 50 as shown in Fig. 4. Also the point 4' on cam I38 will be opposite the nose I 42 so that the point 50 will be at the level shown in Fig. 4. At this time, the shoe I56 of the shogging lever I 5I will be upon the button I55 on the side of cam 81, and this will cause the points 50 to be shogged approximately a half needle space lengthwise of the needle row. The needles will now move toward the press bar 58 and this will bring the yarn against the points 50, so that the yarn willbe caught upon the shoulders 5|. Then the button I 55 will be removed from the shogging lever I5I, and the points 50 will move back into line with the needles.

,During thecompletion of the second full rotation of the main cam shaft, the needle will be advanced upwardly to receive a new yarn, and the auxiliary cam shaft 88 will have completed its second quarter turn movement. By this time, the low button III will have been moved away from lever I09, so that the auxiliary cam shaft 88 will remain idle during further rotations of the main cam shaft. Also, by this time cam shaft 88 will have completed its second quarter turn and brought the point 5 of thecam 8'I opposite the roller 86, so that the welt bar may move away from the needles as the welt fabric is knit. The roller 86 will not immediately move into contact with the cam in position 5, however, since the yarn will be caught onthe points, and this will hold'the arms 69 and I0 toward the needles. The point marked 5' on the cam I38 will be opposite the nose I 42 to thereby determine the level of the points 50.

' Subsequent rotations of the main cam shaft after this second full rotation will cause ordinary knitting to be performed, so that a length of fabric as shown in Fig. 5 will be knit. During this regular knitting of the welt portion of the fabric, the auxiliary'cam shaft 88 will remain in fixed position, so that the roller 86 will be opposite the point 5 on cam 81, and the nose I42 will be at the point 5 on cam I38. The auxiliary cam shaft 88 will remain in this fixed position, because no button of pattern drum A will be under lever I09, although the pawl will oscillate repeatedly under the influence of its actuating cam I00 on the main cam shaft.

It will be understood that when the roller 86 passes beyond the nose of cam 81 between the points 4 and 5 thereon, the roller will not immediately drop into contact with the cam at point 5, inasmuch as the fabric will serve to hold the roller 86 outwardly away from the point 5. However, as the welt fabric is knit and the points 50 move away from the needles .under the influence of the take-up bands I80, the roller 86 will graduallymove inwardly toward thepoint 5 on cam 87.

After a portion of the welt fabric has been knit, as shown in Fig. 5. a low button IIO will be brought under the end of-lever I09 sothat shield I04'will be-moved inwardly and permit the pawl 95to engage notch 92d. The pawl will not 2,379,827. I i I; 9

engage in notch92eat this time, because a high button III'must beunder lever I09 to permit such an engagement; "Asflnotch 92dwillbe the only one which .can'sbe engaged, only an eighth of a turn willbe imparted to the auxiliary cam shaft88. 1

This eighth of a turn of shaft 88 will-'firstact to dislodge the welt rod I18, and, will then move the, points58 slightly toward the needles and also elevate the points, so thatthe relation ,of Fig. 6 results. The welt rod I18 is lnOW' folded in the fabric, and tension, of the take-up belts will be applied directlytothe fabric. l

- The welt rod. IIIl is dislodged by the action of cam element IQB-against stem ISI, and since the bracket 226 is attached to this stem, the shield 223 is moved to inoperative position so that the pawl 2 I8 engages theratchet wheel 281.- The. in-

' creased tension afforded by pawl 2I8 and ratchet 281 is rapidly applied to thefabric, .and is maintained throughout the subsequent knitting of the welt. v v

For the-position of Fig. 6, the roller 88 will be at point 8 on cam 81, and the nose I42 will be at point 8' on cam I 3 8. The followers will remain at these points on cams 81 and I38 throughout the knittingof the remainderof the fabric, as appears from Fig. 6a. During this subsequent knitting the welt rod.I18 moves away from the needles to take upthe fabric, as also appear from After the entire welt has been knit, a; high button III will be broughtunderthe free end of leverIIlS so thatshield I04 will; be moved; inwardly and permit the pawl-951: engage notch 92c torotatetheauxiliary cam shaft 88. Also, at this time the main cam shaft a will be shogged so that the machine will-move through its narrowing motion. a

Two completerotations of the main cam shaft are neeessaryto return the welt pointstothe needles from the position of Fig. 6a, to transfer tion and thezneedles willhave'gone downand upin Fig. 6b andFig'. 7, the main camshaft will have moved .throughaportion of this second full rotaagainto complete the .flrst half of the narrowing operation, or that half ofthenarrowing operation in which the stitches are normally taken from the. needles. During this time, theauxiliary cam shaft .will make a partial movement in-its last quarter turn and willmove the'ipoints from Fig. 6b; to Fig. '1. This will bring point 1 of cam 81 and point 1' of cam I38 to their respective followers, to elevate the points as in Fig. 7, so that they will pass over the tops of the needles.

At this same time, the narrowing frame has been. lowered so thatthe hooks. 205 are inline with the movement of the points50 toward the needles. As a consequence, the pinsl I8 and H9 enter the hooks, as shown in Figs. 24 and 25,and

thereafter the narrowing framewill determine" the. up and down movement of the welt barfuntil the welt bar is withdrawn-under the action of the-spring89as permitted by thecam 81 so as .toremove the pins II8 and H9 from the hooks 285. Since the narrowing frame will control;the welt bar, inthis manner, thedepressionat 8', .9, I0,and I I' in cam I38 is deepened so asto be out of contact with the nose I42, as shown inFig. 24. However, hooks 205 may be eliminated and the cam I38 be. so contouredin this region that it will the loops from the points to the needles, and to restore the points totheir normal positionshown in'Figs. 17, 18, 19, and 23, The first full rotation of ,the maincani'shaft will turn the shaft .88 an eighth turn due to'notch 92a, andthe second full rotation will account for a further quarter turn rotation of the auxiliary cam shaft 88 due to notch 92a. -A high button III must come into action to cause engagement with notch 92c, and a low button III], causes engagement with notch 92a.

During the first part of this movement, the cam element I96 will be removed from stem ISI, so that shield 223 willact to liftpawl 2I8 from ratchet wheel 201, The additional tension afforded by ratchet wheel 20'I will thereby be released and only the tension afl'orded'by the usual ratchet wheel 288 will be applied tothe fabric.

. The first full rotation. of the main cam shaft to I return the loops to the needles will be a regular knitting cycle andwill bring the needles to the position of Fig. 6b. In thisrposition, the needles are just coming up from finishing theknitting course, and it is atthis point that the main cam shaft shogs over to the narrowing position. As

- has been noted, this firstrotation of the main cam shaft rotate the auxiliarylcam shaft aneighth turn to bring the welt points toward the needles, as shown in Fig. 6b.

, The second full rotation of the main cam shaft to return the loops to the needleswill move'the needles through a narrowing cycleand no yarn willbe laid down.- Between the positions shown impart to the points their necessary up and. down movements. V From the position of- Fig.7 on, the machine goes through the second half ofits narrowing cycle, i and the loops upon-the welt points are transferred to' the needles. Theiirst movement of the main camshaft beyond Fig. '2 will cause the needles to drop as shown in Fig. 8, and will rotatethe auxiliary cam shaft 88 so that point :8 of cam. 81 will determine the forward position of the points. As has been noted, hooks 205 are now exerting control over, the points to .move them downwardly.

Continued operation ofthe machine-winning" the needles to the position of. Fig. 9, and points 58 will occupy thev relative position shown due to points 9 and 9' on cams 81 and I38,respectively.

Further rotation of the main cam shaftwillposition the needles as in Fig. 10', and will turn the auxiliarycam shaft so that roller 88 willlbe upon point ID of cam Blandnose- I42 ,will be opposite point'IIl of cam I38..

Still further rotation of r the main cam shaft will elevate the needles as shown in Fig. 11,- and will-move cams 81 andi I38,so their points I I and II' .are opposite their followers. Point II is not acting, however, as hooks 285 still exert their control. I I 7 Further rotation of ,the main, cam shaft positions the needles as in Fig. 12 and the points 50 as there shown. At thecorresponding point I2 of cam 81, its contour is startingto recedeto permitfmovement of the points 58 away fromthe needles. Also point I2" of cam I38is at a high point to maintain the points 58 at a level above the tops of the needles.v v ,1 I

At the endof the'second full turnof the main cam shaft, the auxiliary cam shaft has completed andthe remainder of the fabric will be knit in regular manner. Due to the" fact that two courses at the initial end of the fabric are joined to the fabric when the welt is knitclosed, a stronger connection is' established.
