cular stocking knitting machine generally of the type disclosed in the patent to Hemphill dated September 7,' 1909. In this stationary and althoughthe machine disclosed is for the purpose oitproducinghosi ery it is obviously not limited to thisrclass or wor Generally the machine includes a revolving nee lle cylinder 1 mounted on a. suitable table 2 constituting; a part of the frame of the knitting machine and, as is customary in this 7 type of machine, said cylinder is arranged to.

hereinconsisting of five

pivotal yarn guides

5, 6;, 7 and 8 are plvoted in a well known or, manner to the latch ring 9. In the present example these yarn guides are-controlled by

means including levers

10, 11,12, 13 and 14 respectively pivotally supported at 15 in a standard 16 secured to the table 2, certain 01" said levers being: in turn controlled from the cam drum 28 or the usual pattern drum of said Hemphill machine, In the present eX- ample the levers'lO, l2 and 14L are all shown as controlled by said pattern drum 23 and preferably through the usual wires 17, one of said wires being connected with each of the levers named and with

cam levers

18,19 and 20 respectively pivoted at 21 and arranged to engage suitable abutments' or interrupted ribs distributed about the face of the drum 23 and properly spaced to bring their respective yarnguides into operative position ,at suitable times. in the knitting of the work. The pattern drum 23 is herein shown mounted upon the usual pattern shaft 22suitably iournalled in the frame of the machine to' rotate at certain definite or selected intervals to effect the changes 111 the character and term of the work.

A forward intermittent rotary motion-is imparted to the pattern or cam drum 23 preterably by the usual pawl 24 carried by the usual segment 25, the latter being oscillated by meansoi the gear 26 througha connect- I ing rod 2'? all oil which parts are included in the needle carrier reciprocating instrumentalities ot' the above mentioned llemphill machine. The pawl 24 is arranged to operate upon a suitaole ratchet 28 secured to rotate with the cam drum 23 see Figs. 1 and 13 and the engagement of said pawl with the teeth of said ratchet is herein controlled by lugs 29 on the usual pattern chain 30 through the medium oil the usual llemphill controller 31. A pattern chain 30 is mounted upon a sprocket 352 to which a step-hy-step movement is given by the usual operating pawl El carried by the segment shovvn in Fig. 13, said pawl acting upon a ratchet 33 attached to saids n'ocket 32 in the usual manner.

In addition to the regular yarn changing devices hereinbeilore described Which include the pattern cam 23 I have provided an additional, or What 1 term a siq' pleincntary or auxiliary yarn changing device, one purpose of Which is to etlect zulditional changes in the Work Without necessitating; an enlargement of the pattern cam 23 or the lengthening of the pattern chain yet enabli: yarns of ditlj'erent colors to be inserted at predetermined or selected points in the lmitting.

As an example of mains for accomplishing the said results I have provided the ittl2- iliary cam member Zlalherein oscillatorily mounted upon a stud 35 secured to the stand ard 16. The cum 3% is 0i. disk term and has a notch-in the rim thereol which forms, at opposite ends,

cam surfaces

36 and 37.

Cooperathu; respectively ivitl'i said cam surfaces are levers 3e and 39 pivoted at l0 in afixed part of the frame, the free ends of said levers having eyes ii to receive Wires 42 and 3 depending); respectively from the operating levers 11 and 13, said

wires

42 and 43 having collars let secured thereto and against which the eyes ll ahut \vhen acted upon by their respective levers. The cam surfac 86 and 3? are so arranged as to autoi'natically engage their respective levers 3S and 39; that is to say din. rag: the oscillation of the member 3% clockwise or in the direction of the arrow, Fig. i the cam 36 which is assumed to be out of engagement with its lever 38 will be brought into engagementtherewith and depress said lever from a position shown in Fig. 7 to one correspondingz to that shown in 6 While the le er 39 which, at the start assumed to be in engagement with the circular fieriphery oi the cam member 34; adjace. to the cam sur; 37, will be released by such movement and moved to a position corresponding to that shown in Fig. 7. A. result of the movements of the

levers

38 and 39 from the positions shown in llig. 4; to those shown in Fig; 5 is to lower the yarn guide 7 from an inoperative to an operative position and to raise the y guide 5 from its operative to its inopen position While the movement of the oscillzn tory member 3a in an opposite direction to that indicated by the arrow in Fig. 4 Will ause the said yarn guides to be returned to their former position. Obviously the moveroent ot the member 34: need not necessarily l)0 an oscillatory movement but Where such is employed it is desirable to provide means tor limiting or preventing overthrow of said incnihcr and herein for this purpose a pin li) is provided in the pi "iphery of said cam to en grq'e suitable abutments as for example the ends :16 and 47 of a slot a8 formed in one side of the standard 16. ".lhe oscillatory movement of aid cam may be eilected by various means and herein I have provided means op erating continuously with the driving elements of the machine which means include a plunger arranged to reciprocate vertically herein in suitable hearings including the table 2 and a bracket 50 secured to the frame or :he machine. The lOWQl' end. of said plungis arranged in operative relation to an arm oil the oscillatirur segment 25 so that for each movement of saio arm, said plunger all) will be moved a predetermined distance in its guides.

A collar 51. is herein shown attached to the rod or plunger 4-!) above the bracket 50 and when said plunger is in its lower position, said collar rests against said hracket so that the downward movement of the plunger will be limited thereby. A sgring 52 encircles said phu gel between a suitable fixed member, such, for iii-dimple, as the tahle 2 and said collar 51 so as to exert a yielding pressure against the plunger in opposition to its movement by the s The lower end of said plunger is herein shown as having an adjustable contact member herein consisting of a screiv ha vine screw-threaded engagement With said plunger and adapted to he held in the dei-iired position by a check nut lllounted on the table 2 in suitable bearinns is a rock shalt having loosely mounted thereon a bell crank lev r 56. This bell crank lever has two

arms

57 and 58. the arln 57 of -which extends toward. the plunger 49 and has at its free end a roll 9 adapted to roll in contact with the end of the plunger projecting: al'iovc the table 2. The relation of the ro l and plunger is such tha 1 when the plung-- in he lowermost 'ios tion, the roll 59 rests upon the upper end of the plunger as suoivn in 4; but as said plunger moves upwardly the roll will inve therewith for a ment 2 predetermined distance or until the end of i said plunger clears said roll. whereupon said roll will merely have rolling en; igreinent with the side of said p is any 'l'urther upward movement thereof. and no imparted to the plunger. Attached to the free end of the other arm 58 of said bell. crank lever is an actuator or pusher 61 which extends toward by effect alternate engagement of the cam tacesSG and 37 with their levers 3S and S9.

The pins 64 and 65 are disposed upon opposite sides of the axis or the cam 34: and are at such a distance apart that When one of the shoulders of said pusher is in contactvvith its 4 abutment or pin the other shoulder Will not engage its pin. Obviously Withthis arrangement of the stops and pins the permitting of one shoulder to remain in alignment With its abutment or pin tor a number of consecutive movements of the pusher 61 will result in the yarnguides remaining unchanged for that period of operation or until the pusher is moved so as to cause the other shoulder to engage its pin.

The arrangelnentot said pins is such that when one shoulder moves its pin forward the opposite pin will be retracted to a position Where it Will be operated upon the next forward movement of the 'pusheror when the shoulder for that pin is moved to align therewith. It is, therefore, desirable to provide means to effect the shitti. of said pus; from one pin to the other Whenever a change is desired and, tor-this purpose, 1 preferably provide means including'the pattern chain 30 for accomplishing such a result and upon which are formed a series of lugs 66 (see Fig. 2 said lugs being formed upon the opposite side ottlie chain tr in the regular lugs 29 for actuating the controller 31. Ohviou'sly these lugs (SS-may be arranged at any desired points on the chain to effect the yarn changes, and the sh pc or shapes thereof may vary according to the purpose desired, as will. hereinafter be more fully described.

Cooperating with the lugs (36 is a pawl 67 pivoted herein upon the same stud v ith the controller 31. Connected with said pawl and iir eferahly upon the opposite side from the portion thereof which engages the lug 66 a rod 68 Figs. 1', 2, 5 and 8) the upper end of which h as sliding engagement with the table 2 through which-it projects and carries at i 5 ext inity a finger 69. Surrounding said rod between. said finger and the table '2 is spring 70 which acts to maintain said rod in its elevated position with the end of the g *Y "7 n .fwi v 1 the f 1 in; w t, panl 6! in contact M1 1 no ("L6 or the pa tern chain and operates in opposition to'thc raising of said pawl by the iugs (36. The o9 is arranged to project beneath the pusher 6i. and When theiinger is in its mevated positionthe pusher will he supported thereby with its shoulder 62 in a position to operating; contact Witl The action oi the can;

engage the lug or pin 6 so that each movement of said pusher toward the left would, after the first movement of the cam 6%, he an idle movement but when a change is to be iade in theyarn one oi. the lugs 66 on the patte n chain passes beneath the end of the shoulder 63 elevating said end, co npressing the spring "1'0 and depressing the li er 69, thus permitting heshoulder 8 to drop to its lower position Where, upon the forward n'ioveinent of said pusher, said shoulder Will the lowermost pin 65 and lock said cam. I l

Naturally the movement the pusher from the one position to other may take place when said pusher is in its i ervm do position.

'Hence the rear portions of the shoulders and (Bare so shaped, and the raising and said means herein consisting of a lever 77 of goose-neck :lormation. The nose 78 of said lever 77 is arranged to engage the periphery of the cam 3a, which latter is provided with a recess at its edge forming a cam surface 79, alternate movements of said cam being" adapted to cause the nose 78 of saleL grooscnecl-t lever to pass from the outer periphery of said cam 34: as shown in Fig. l into said recess and against th 2 aim surface 79 or from said latter position to the tormer according to the direction of movement of said cam.

'l he lever 7'? is eausedto iollow the periphery of said cam 3-4 by pressure exerted thereon by a spring: 80 so that the nose 78 ot said lever will, at all times, he maintained in contact with said member he lever 77 is herein shown loosely mounted to the shaft to rock therewith and also secured to said shaft is an arm 81 carrying; at its upper end a pin 82 adapted to engage the under edge ot a lever 83, the latter being pivoted at 8% to a fixed. part of the inacl'iine frame, herein the supportine' standard for the latch ring 9.

The lever 83 is arranged to cooperate atone end. preterahly the end opposite to that engaged by the pin 82, with an arm 86 projecting laterally from a collar 87 mounted upon the. cutter artuatingr link 72 (see Figs. 4: and 5). The arm 86 is PUSltlOllQCl normally to intersect the path ot n'ioven'lent ol said. lever so that. when the end of said lever whose path of movementis intersected by said arm depressed, said arm 86 will he swung out- 'ardly away from said lever sutlicient only to allow the end of said lever to pass below the said arm. To facilitate the movements oi said arm. the collar 87 has a limited rocllin movement upon the linlc 72. which move ment is in op 'iosition to the action ot a tersional spring" 85% herein arranged to encircle a. portion ot the linl: 72 between a collar 89 secured to said link and a collar 8? bearing the arm 86. opposite ends of said spring being: connected respectively with said collars.

As previously stated the collar 8? has a limited roclrin movement upon said link 7 2, the purpose whereof is to confine the action of said spring within certain predetermined limits. As a means or limiting the move ments of said collar I have herein provided the same with a tooth or altiutn'ient 93 which extends upward into a segmental recess 91 termed in the under side of a collar 92., the latter beingrsccurcd to the link 72. Opposite ends of the segmental slot 91 iretcrably constitute :mutments against which the ahutment or tooth 9?, is arranged to strike in its pivotal movements, the abutment. 9O constitutingr the means for maintaining the arm 86 normally in the path of the arm of the lever 8 During); the normal operations of the ma chine, the lever 83 remains either in the position shown in tall lines in Fig. a or in that position indicated by the dotted lines,

Fig. 5, in either of which positions the end 95 of said lever will be above rather than below said arm, and when the link 72 is raised by its regular operating means, as for example the cam 75 and the parts operated thereby, the arm 86 will merely idle against or near the curved end 9% 01 said lever 83. But when a change is to he made in the yarns controlled by the'auxiliary cam member S-l, at which time it is desirable to clamp and cut the yarn that is withdrawn, said lever 83 will he rocked about its pivot 84; so as to cause its squared end 95 to be moved below the arm 86 where, upon a reverse movement of said .lever 83 will raise the arm 86, and through low the arm 86, said lever 83 is provided with inclines 96 and 97 upon its under edge and at the opposite side of the pivot 84 from the end of the lever which cooperates with the .arm 86. The inclines 96 and 9? are at times engaged by the pin 82 carried by the lever 81 which pin and lever oscillate with the gooseneck shaped member 77 and each time the as cillatory cam member 3a is moved from one of its positions to the other to change the yarns.

By reference to Fig. 4 it will be seen that the pin 82 is at the right of the incline 96 ot' the lever 83 and the nose 78 of the lever 77 is held by the spring in contact with the outer or circular periphery of the cam memher 34-. The parts referred to remain in the positions indicated until a. change in the yarn or yarns is to be made through the proper instrumentalities, or until the linger 69' operates to vary the position of the pusher or actuator 61. From the positions illustrated in Fig. 4 of the parts to which reference has just been made, said parts will move upon the next operation of the machine to the positions shown in Fig. 5; that is the pusher 61 will be lowered so as to engage, through the shoulder (33, the pin (55 and as said pusher moves forward, the cam member 34: will be rocked to bring the cam surface 79 in a position to be engaged by the nose of the lever 77 whereupon the spring 80 will cause said lever to follow said cam surface and move with it the lever 81 and pin 82. During this latter movement the pin 82 engages the incline 96 and causes the end of the lever 88 hearing said incline to be raised while the opposite end of said lever is depressed, the inclined or rounded portion 94 thereof engaging the arm 86 and rocking the same upon the link 72 from its normal to its deflected position suflicient to allow that end of said lever to pass th-erebencath and after said end has cleared the arm 86, the spring 88 acting upon the collar 87,- causes said arm to returnto its normal position above and in contact with the surface 95, the opposite end of said lever being held in its elevated-position shown in Fig. 5.

The various parts just described are de signed to function at a certain definite time with respect to the rocking of the cam member 34, Whichlatter effects the change of yarn, but'this mechanism operates merely to maintain the lever 83 in such a position that it may subsequently be acted upon to open the jaws of the cutter and clamping devices and in the present example I have shown means consisting of a cam 98 attached to a predetermined portion of a revolving part of the machine as for example the needle carrier so as to engage the uplifted end of the lever 83 and depress the same, In view of the fact that the arm 86 is at this time above the end 95 of said lever 83, said arm will be lifted together with the link 72 and the cutters and clamping devices will be opened to receive the yarn, The pivotal movement of the lever 83 under the action of the cam 98 continues until the end 95 of said lever escapes from the arm 86 but not until said arm has beenraised sufficiently to open the jaws of the cutters and clamps and as the raising movement'of the link 72 is in opposition to the spring 85, said rod will, upon being released, return to its lower or normal position and thereby cause the yarn clamping device to clamp the yarn and the cutter thereof to sever said yarn.

Obviouslythecam 98 may be placed in any desired position on the needle cylinder and may be of any length consistent with the proper performance of its function.

There are occasions, as for example when a knitting machine is operating reciprocatingly when it is desired to pfovide means for taking care of slack yarn produced by the turning back or reversal in the direction of movementof the needle cylinder or,-in some cases, of the cam cylinder and in machines of the character set forth herein such devices are usually employed,

, In thepresent example is illustrated a common or known form of take up or tensioning device consisting of a vertical shaft or stand aid 99 arranged herein at the back of'the 7 machine (see Figs. 1, 11 and-12) which supports an arm 100. At the outer extremity of said'arm are provided yarn guides or

eyes

101 and 102, the holes through said eyes being disposed in substantially;uprightpositions and in close prorumity to said

eyes

101 and 102 are other thread eyes or guides 10 3, 104 cooperating respectively with the guides 101', 102. The guides 103,104 are positioned shghtly ,above the

guides

101, 102 and the holes therein extend substantially horizontal or approximately at right angles to the holes in the

guides

101, 102.

Near the inner end of the arm 100 are

other eyes

105, 106 through which the yarn is led from suitable yarn masses to the

eyes

103, 104. Interposed bet-ween the yarn guides or

eyes

101, 103 is a movable guide eye 107 mounted at the outer free end of a pivotal take up arm 108, the latter being arranged to rock about the axisof a pivot 109 near the supported end of the arm 100. The arm 108 is arranged normally to be maintained in its uppermost posisition referred, to, means are provided for depressing. the arm 108 and inthe present ex-e ample the means employed for this purpose includes a wire rod113 arranged to slide in the arm 100 at 11 1, thelower end of said wire being attached to a stud 115 pivotally supported in the outer end of an arm 116 secured to the rock shaft 55. The

guide eyes

102, 104 also have a cooperating take-up guide eye 116 mounted in an arm 117 similar to the arm 108. Said arm 117 is likewise pivoted as at 118 upon the arm 100, the axis of said pivot being substantially coaxial with the axis of, the

pivot 109 for the arm 108.

A spring 119 acts upon the arm 117 to maintain the arm 117 in its uppermost position as shown in dotted lines, Fig. 12, said spring being attached to an extension of said arm 117 and to a fixed bracket similar to the bracket 112. The arm 117 is held, at certain times in the operation of the machine, in its lowermost or depressed position by a rod 120 similar to the rod 113 hereinbefore described, the rod 120. being of the usual type employed in the Banner machine and operated by suitable instrumentalities not shown or described herein.

From the foregoing description it will beobvious that circumferential stripes may be produced in the leg or foot portions of the stocking and moreover the heel of the stocking and in particular that part of the heel which is produced by reciprocating knitting and by so-called narrowing and widening,

may be formed of yarn differing in color or character from that composing the regular loops of the fabric. Likewlse the tip of'th'e toe which also is produced by narrowing and widening may be formedof distinct yarn and these results may all be obtained merely by the insertion of special links at selected points in the pattern chain and without un necessarily complicating the machine or necessitating the addition of a prohibitive num ber of links in the pattern chain. i

Although the machine embodyingthis invention is capable of producing a large variety of designs-in striping, a single example Q Lees is shown in Fig. 1 In this example, let it be assumed that the yarn composing the body otthe stocking white and in this white body, as indicated at a I insert a plurality of eircuinterential stripes 7) torn'ied tor example of blue yarn. Also let it be assumed that that portion of the heel pocket produced by narrowing and widening is also formed of blue yarn as indicated at c and at the toe of the stocking the portions thereof that are produced by narrowing and widening are also lrnitted with blue yarn as indicated at cl. lit should, however, be understood that the stocking is not limited to the design described.

Assuming now that the machine is to be threaded and adjusted to produce the eicample shown in Fig. 1"; lirst the pattern chain 3-50 may be adjusted so that the links bearing lugs (30 (see Fig. 2) will be placed at the proper points to engage the pawl ($7 for the purpose of effecting changes in the yarn.

It will, however, be noticed by reference to Fig. 2* that the lugs are oi two kinds for example the lugs 121 are shorter than a second set of lugs 122, the latter being long enough to overlap each other to the extent that when two or more of these l ,s are placed next to each other the pawl. 61" will be elevated and maintained in its elevated position until all ol:' the overlapping legs of the group have passed, whereas with the lugs 11.21 the pawl 07 will be raised and permitted to drop back to its former position before a second in is brought into engagen'ient there with. The result of the arrangement of the lugs, as statechis that when the group of loan 122 is acting upon the pawl 67, one yarn will be employed continuously throughout the entire series of lugs while with the lugs 121, two yarns will alternately be ei'i'iployed. Thus in knitting the sections 0 and (Z the lugs 122 will be engaged while the stripes 7) will he produced alternating with the regular yarn when the lugs 121 are acting upon the oawl (3'7.

'1 1e stocking illustrated in Fig. 1 involves the use of only two yarn guides viz, the yarn guide 5 and the yarn guide 7 (see Fig. 8), the guide 5 serving, in the present example, to feed the white yarn to the work while the yarn guide 7 leads the blue yarn to the work.

The regular yarn guides 4:, 0, and 8 which are operated in the manner common to the Bannefi knitting machine willv not henceforth be referred to in the ope 'ation (YE the machine although obviously there are many of work where all oi the yarn guides of the machine may be utilized, Obviously any one oi? the regular yarn guides 4;. (S, 8 can and especially the latter, in which event one llrietly the operation of the machine is as follows: 'lhe white yarn herein used in the body of the stocking; is threaded through the guide 100, eye 10%;, take-up eye 116 and. the guidocye 102, thence to the guide-eye ot' the yarn lever 5, the latter in Fig. 8 being shown in its operative or yarn feeding position. 'llhe blue yarn is similarly threaded through the guide 105,

eyes

103, 107 and 101 to the ya u lever 7.

A suuiiing the machine to be operating to knit tubular work, the yarn guides remain in the positions indicated in Fig. 8 and with their a etna ti up; parts as shown in Fig. 4; from which it will be seen that the two take-up

arms

108 and 117 will be held depressed as shown in Fig. 12 by the

wires

113 and 120. ll hei'r the point in the knitting is reached where a cmisiderable section of stocking is to be knitted in solid blue as for example in the tip oi the toe, the lugs 122 are brought into engrag reinent with the pawl 07 so as to raise the end ot the pawl. engaging said lugs or depr' *ng the opposite end thereof.
