STITCH-CHANGING MECHANISM FOR KNITTING-MACHINES.

Specification of Letters Patent.

Patented Apr. 7, 1915.

Application filed October 26, 1912. Serial No. 727,902.

To all whom 'it may concern.

Be it'known that I, D ivn) B. Kines, a

.citizen of the United States, residing in Spring City, Chester county, Pennsylvania, have invented certain `improvements in Stitch-Changing Mechanism for Knitting- Ma-chines, of which lthe following is a specification.

My invention relates to knittingand consists of improved mechanism for knitting machines.

My inventionis particularly serviceable when used in connection with knitting machinos such as are capable of producing different kinds fof loops or Stitches, as for example regular (including plain and rib knittinghor tuck knitting and which is used extensivelyA in the production` oftubular fabric for'use. inthe manufacture of undergarments where the bust and 4hip portions are made of tuck l knitted fabric and the waist vportion is made of regular knitted fabric. Heretofore, there have been vices employed, yon knitting machines of the above'j-desc'ribed type, for automatically ef-.'-

fecting the v'changesin the character lof the knitting, but as these devices were so complicated and unstable they often'got out of order or out of their proper combination for effecting a change without the operators no- 'ticing it and would often spoil' fabricsby making the-changes at improper vplaces and -len ths.

ne of the chief-objects of my invention is to equip a knitting machine with mechanism which will automatically actuate the machine to effect changes in the character 'of the fabric beingv produced and which will.

be positive in its action and net getvout of proper combination while running. 'A1so.

that the construction will be suchI that ifthe mechanism be started in an improper posir tion the same will right itself after a short time and continue to make the desired com-- bination-of-fabric structures.

Another object'rof my invention is that lthe same will be'of simple construction, durable,

, and will require Very little power tofoperate.

. These objects and other advantages which will be .described hereinafter, 'I attain in the following manner reference being had to the accompanying drawings'i'nwhich: Figure 1, isa slde elevation ofpmy invenvariou's -deting of the fabric; Fig. 4. is a view similarV to Figs. 2 and 3 and showing still another position of the parts during thc knitting of the fabrics; Fig. 5, is a plan View of Fig. 2; Fig. 6, is an'end elevation of Fig. 2 looking' in the direction of the arrow X at the right;

Referring `to the drawings, ;1 is the ma-in 1 frame' of a knitting machine having a stationary bed- 2 securedltheleon, Said bed forming a support for erota nblecam cylinder 3 havin a came secured thereon. Ah

arm 5 is rigidly securedto'thef" d2V and is f provided with a bushing' 6 for la" vertical sliding rod 7 having a disk 8 secured to its upper end. Also, the arm 5 isiprovidedh with a shaft 9 which formsa pivotal bearing;r

- for a! diskv raising .lever 10 anda .chain actu'- atedglever 11, the arm .having -in addition a y fixed bearing for a lever extension 12; the

so 7 Fig. 12, is a perspective View of Lspecial chain 2O is mounted on the sprocket wheel 17 and adapted to move thereby when the lattav4 is rotated. The chain 2 0 is provided. wth links of variable heights and as shown in the present instance comprises the ordinal-z' coni pling links 2l, medium height links 5: and 23, and hi h links 24 and 25.

A shaft anger 26 is rigidly secured to the frame 1 and forms a support for a shaft 27 having secured thereon, adjaecnf one end a picker wheel 28 having pointed ins 22) projecting from its periphery andadapted to engage the knitted fabric ar: it passes downwardly froth the machine. A bevel gear 30 is loosely mountedon the shaft "7 and is provided with a pin 31, and a sleeveY 32 which is adjustab'ly fixed to the shaft `.27 by' an adjustment screw 33 provided with aprojection 34 which extends for al portion 'of the circumference of the sleeve.l The pin 31 on the 'gear wheel 550 is so placed that the latter may be ric-tated for a fractional part of one revolution without the pin 31 coming in contact with the projection 34, 0r 'vice versa,the sleeve can be rotated for a fractional. part of a revolutionv when fthe pin 3i and projection 34 are not in contact. without the projection tmoving the-plinl, as, there is Va movement' in the present invention lwhere the sleeve '32'forms the: active nem ber and tends to rotate the gearthrou hl the medium of the pin 31,-and there 'is a a movement when the geur 30 smoved in dependently of and at a greater speed-i'r.'the

same direction than the-movement ,ofl the sleeve 32, and it will thus be seen that, as the movement ofthe said ear 30 moves faster than the movement o the collar or sleeve 3". during the previously mentioned` theremustbe provision fr the'movement of the pinl 31 without .the latter effecting the movement of the sleeve 32 for the reason lthatfthe latter receives itfs movement through the Vmedium of thewheel 28 `from the .fabric moving downwardly and that if the wheel "28 received emotion greater than the speed of the take` up 3f ijf the Vfabric..being'pro` lduced, the-'same would result in: thefabric A bracket 35' having one end;suppo'ted- :by the lshaft 16 andthe other end supported .by the shaft 27- formsa 1jo\1rnal fora shaft 3G having securedfat one en'd-abeveled gear A37A ,-which meshesff with the, 'geal' 19 on the.

independent movement of tte said gear 30,

shaft 16, and has secured on the opposite end a beveled gear 38 which meshes with the gear 30.

double ended lever 31" is pivotvd at l() t0 the frame l and has pivoted at one cnil an antifrirtion wheel all, and. :it the opposite crd, a pivoted pani 42 adapted lander certain conditions to engage the teeth of the ratchet wheel l. om` end secured to the lever 89 and the other und :si-cured to the frame 1 and acts to keep the antifriction wheel in the path of and so :is to be engaged by the cam 4 during each revolution of the cam cylinder 3. The lever 10 is provided with aforked projection 10a; the depending prongs .10b and 10c forming a. forked end. The high linke 24 and 25 are cutaway alf- 24a and 25 respectively and the lever 11 is so arranged that its forward end 11 rests on the chain4 links on the sprocket wheel 17. Also, the forked end 10 on the lever 10 is ofzsuch a length that the prongs 10" and 10c straddle the 's'aid end-11L of the lever 11. A stop 5 on the arm 5 acts to limit'the lower movement of the lever 10, .such a position o f the lever'being shown in Figs. 1, 2 andv 4.,'and showing the prongs A tension spring 43 has 10'V and" 1()c sli htly clear of the links 21 -A Y on the chain. .f lso, this position of the lever 10, the sliding rod 7, and disk 8 vare -in their lowest position, and the disk 8 is lar knitting switch M clear of the lre and the i tuck switch 45; said latter switches being of any ordinary construction,

and may be of the type shown in theaccomi panyingdrawings.

The free end 14 of the lever 14also normally restson the top 'of the plate 48 and the free end 11.a

wonttiiiziigf gear 30, that the pin 31, which was previously being moved by the projection 34 on the sleeve 32, will move away from the projcction 34- at a greater speed than the continncd movement ci' the projection 34 and thereb) tend to increase its distance from the said projection 34. The distance between the pin 31 and the projection 34 will tend to increase during the said movement of the ratchet wheel by the pawl 42, which in the premnt instance is to the extent ot' two teeth, although, when the pawl 42 is disengaged. as 'ust mentioned in the ope `ation of .ne machine, the ratchet wheel 18, sprocket Wheel l? and necessarily the 3l vvill stop until the projection 34 on the sleeve 82 catches np with the pin 31 and again moves the latter and thereby the sprocket 17 and the chain 20.

When the medium height link 22 reaches a position as that occupied by the link 25 shown in Fig. 2, the highest point of the link 22, which siilistantiznly equal to the height of the portion 25b of the link 25, will raise the lever end 1l into the position occupied in Fig. 2 which will again cause the end 14 of the lever 14 to depress the plate 48 and thereby allow the pawl 42 to engage with the wheel 18, then on the next rotation of the head the cam 4 will act through the medium of the antiriction wheel 41 and the lever 36 to operate the pawl ft2 to move the ratchet wheel 18 to the extent of one tooth. This movement of the ratchet wheel, which is consequently imparted to the sprocket 17, tends to move the link 22 under and raise the prongs 10b and 10c and thereby causo the lever 10, sliding rod 7 and disk 8 to be raised into a position so that the latter will be struck by the tuck fabric switch 45 and thereby canse the machine to be changed so :ia to again knit tuck stitch fabric, such for example, as indicated from (I to I) in Fig. 15. Thon upon the next rotation of the head the ratchet wheel 18 will again be moved by the pawl 42 g this latter action causing the link 22 to be moved away troni the prongs 10 and 1Qc of the lever 10 and also from the cnil 11n ol the lever 11 allowing the lever 10 to drop against its stop 5b and thereby lowering the disk 8 ont of the path of the switch loi ers and also allowing the pawl l2 to be disengaged from the ratchet wheel 1S in the manner heretoA fore described in connection with the link 25. This latter movement ot' thc ratchet wheel 18 by the pavvl 42 again caisses the pin 31 on the gear 30 to move away Vfrom thc projection 34 on the sleeve 222 as heretofore described. Also, when the pawl 4t2 is disengaged as inst stated the pin 31 has no motion nntil the projection Si on the sleeve 32 again catches up therewith as previously described.

After the passing of the link 22 as just rear 30 and pixrowfrom A to B in Fig. 15;

` which often lcaused great lossA maratea stated, the machine. will continue to prodnce tuck l fabric until the high link 24, which is similar to and acts the same as the link 25, again changes the machine so as to pro duce regular fabric. However, as shown in the drawing the distance between the high link 24 and the medium height link 23 is such that there will be a quick change, due to the medium height link 23, which is simirr lar to the medium height link 22, to quickly change again after knitting a small portion of regular fabric from E to the nekt repeat of A, to knitting tuck fabric which Vit will continue to knit similar to the portion thus forming an automatic repeat ot' any combinations of fabric.

The regular" portions of fabric which are produced, due to the action of the high link 24 and until the link 23 changes the machine to tuck fabric again, is repre-l sented in Fig. 15 from D to the repeat ot" A and produces narrow portions of regular knitted fabric which may be used as gage lines for cutting the fainics into garment. lengths; the portion of each length from A to B serving to form the bust portion of the garment; that from B to C forming the Waist portion of the garment. and that from C t0 D forming`the hip and the garment. Vhile the machine. as shown in the drawing, will act to torni tour changes before a repeat. a chain 20 having any combination of changes can lic appiicd lo thegsprocket Wheel 17.

Heretofore there hare been machines manufactured for making changes in the chan acter of fabric which has a plurality ot chains and sprockets; one chain acting as a key chain to determine the mo'fement of another chain for eliecting the changes. Howe\ er, as these chains had to operato in proper combination and rcoiircd sk ll and much attention for then manipulation and changes in order to bring tlnproper corn binations the saine were n.=t desirable and were often the cause ot' inniei'tect work to the mannk facturer. lith my invention l use but one chain which is positive in its operation and will only tend to actnate the machine predetermined by the links therein.

. With my invention it' a machine 5r started before or after the proper link has acted upon the lovers 10 and 11 as determined by the character of fabric ilesired, the mechzinism will right itself after a fractional part of a garment length has been produced.y For examplc, suppose the operator dcfircd to productgarineni lt figths of the partira lar combination af shown in Fig. 13, and instead ot starting the machinewhen the link 25 is just ready to act., would have the ortion of the chain which is liaftwecn the links 25 and 22 directly beneath the prong leg portions of f portion 10" and 106 of the lever l0. The marhinc thus improperly started will knit the. fabric as #rescrihefl hy the arrangement of the links :llitil the high link 25 come; in Contact with anrl raises the larmlli, allai' which th@ niachii'ir` will cuntiamr to knit rho lirulmywnihinatifiii nl" faln" 'ihm a nzai'fhiiia ffmistriirtcil in arrurilailw with, niv invrntmn will not contlnury l@ make 1in propri lengthL` ihr-i rpc (al ihr market.

However, either the lever 46 or the weight 55 can be used to give the desired re suit.
