Referring purtirulnrlj; to Figs'. j., 3, 3, i nud l is the, umin shaft, which car Eestivo driving pulleys :t :nul The pulley will lie eluteli couueeted to the. Shaft :is usual, while liuc pulley 3 will be` eomu-.rteii by :iu-:ins of :i speed rexueing geur cmitziined within the pulley .so that for the Saune belt speed. the drive of the xmaehine wil be much slower when the driving holt is shifted from the pulley .5 to (he pulley 23. S this m' chine of the type in which the rotary movement employed while knitting the top and leg,r of the Sock is changed to an oscil lating rotary moven'ient during the knitting of the heel and toe portions, the change of, speed is necessary. Any suitable speed reducing gear might be employed, and none is therefore illustrated as the employmentof such speed changing gear is old in the art.

The countershat't Ll is journaled at .the hack ot the machine, which shaft is geared by means of the bevel gearing 5 to the vertical shaft 6 journaled at the back of the machine. This vertical shaft, by means of the gearing 7, drives the upper cylinder 8, and by means of the gearing l) the lower cylinder l0, and by the gearing 11 the rotary disk 120i" the work feeding mechanism.

The countershaft l is given either a continuous rotary or an oscillating rotary movement from the shaft l by the following mechanism. 0n the shaft 1 is secured a )sprocket wheel lil, which by means` of a Suitable sprocket chain drives the sprocket 1wheel i4 suitably journaled on the frame. iSuitably connected with the sprocket wheel i4 is the sprocket wheel l5, which by mean; of a suitable sprocket chain drives the Sprocket wheel il; suitably journi'iled on the frame ot' the machine. tiuitably iournaled and connected with the sprocket wh Y iii is the sprocket wheel i7 which by means of a suitable sprocket chain drives the sprocket wheel i8, which is secured to a clutch member l) loose on the counterahat't 4. lf this clutch member l) be given a driving con4 nertion with the shaft it in evident that the latter will be given 'a continuellel rotary movenient as long as 'the main shaft is; eontinuously driven.

Vi`he oscillating rotary movennnt ol' the shaft is etl'ected `through the following mech" anism: clutch member fili loose in the countershaft *l has a sprocket wheel 2l se cured thereto. spriicket chain runs on this sprocket wheel 2l and also around a sprocket wheel 235 suitably 0iomnaled at the front of the machine. The Sprocket wheel J6, (see particularly Figs. 3 and 5), carries a headed pin'Lfi, the head of which is adapted tofilide in guides 25 formed on the bar 2G which is adapted to slide on the parallel guide rods 2T, (see particularly Fig. 5.) 'This elidinrr har 2li is suitably seiured at to the sprocket chain The result ot' thin construction is that the rotary movement o? ihr sprocket wheel ll', which is continuously driven ia transformed into a reciprocating movement of the bar li', which imparts a similar movement to the chain. 32, which consequently imparts an ozicillatingr rotary movement to the sprocket wheel il and the clutch member 2() to which it is connected.

The nature of the drive imparted to tlul countershatt al depends on ivhrh oi' the conne i ,leerse chit/

ch members

19 and 20 is given a driving Connection with the shaft. The driving tion off either of these with the shaft etliect l 29, which as usual is slidable on the shaft but is rotatable therewith.v 1t this clutch member be shifted to the right to engage the clutch member i9 (see Fig. the counterehatt will be givcna continuous rotary movement. It Iit be shifted to the left to engage the clutch member 20, the countershat't will he given an oscillating rotary movement.

firm/agement of he 'work feed/ng mechmism--lefore considering the parts of' the mechanism specially connected with the knitting operation, will first describe the auxiliary mechanisms of the machine, and at this point it will be convenient to set out the construction and arrangement of the. work feed mechanism, which, as previously Set out, is driven from the vertical shaft (i by means of the gearing Il, and is sup-r ported on the (liek 12,.

The disk l2 suitably journaled on the plate 3U around the edges of an opening therein, theilisli itself also having an opening atI usual tor the passage ot the work. (ln the dish'. standards 331 are `iournaled the Vfeed rollers one of which is pressed toward the other by means of spring actuated piuncers 33 such as: commonly employed'for similar purposes l(see Fig. lo). These rollers at opposite ends are geared together by meani` of the pairs of intermediate gears 2li. This arrangei'nent permits of the separation of the rolle-ris' as Widely HS muy lle necessary without interfering with their drive.

. time of the rollers at one end carries the gear wheel 35, which. meshes with the rear licei xi 'the shaft Il? journali-d ou the 'ndariia 353., and having secured thereto .itermediiite its; ends ay worm wheel 3H. riiiis worin wheel meshes with the worm 3i) vertically journaled on the disk 12 and havine' :ured to its; lower end a gear pinion Jill. lnis gear pinion meshes with the internal annular gear wheel 41, which is loosely journaied on (op oi' the plate 3&0 and is frictionally held .so that normally it docel not rotate, a lai-"alie irirtionalljy' holdin@r the internal gear wheel from rotating; as shown more particulaizy in litiga. .il and lll.

L'l/3 a brake shoe suitably guided on the tramo and having; thc rofl. il Secured therete and extem'iing through :in opening in the cater end of the traine Alil. rl'he outer end of the. frame is counterhored and a plug 4-5 is screwed therein through which the rod #il passes. Coil spring 46 surrounds the rml filland hcara againat the hraln' shoe l2 and against the plug 45. The liu-alie shoe is thus spring: pressed against thc outer rim of the internal gear 4i, and the tension of the .Li by arcane of the clutch member thus kept 0n the work without undue strain,V

and the degree of tensionv may be readily regulated by adjusting the plug 45.

T o enable the work to be pulled back for examination when necessary, the gear wheel 35 instead' of being secured to. the spindle of its roller 32 is loose thereon and is. connected therewith by means' 'of' a ratchet clutch. Iart 194 of the clutch-is formed on the gaair wheel and the

movable part

1,95 is slidable on a feather key on the spindle. The parts of thc clutch are normally yieldingly held in engagement by the 'coil spring,r 196, which-bears against the clutch member 195 and a eollar 197 secured to the end of the. spindle of the roller.

(.rmr-ol, mccL/mism.-fl`hc control of the needlesl to effect :the desired changes of needles during),r knitting` is obtained by means of the following" mcchanism: A Cam drum Ll'is secured to a shaft 48 suitably journaled ouV one side of the machine.

These drums are provided with cams to effect various movements as hereinafter described.

:mechanism: A shaft is geared to theV main shaft l by means of the bevel gearing ."il. lhe `shaft extends toward thc'front of (hil umchine and has the cam lSecured thereto. comici-.ting rod 53 is provided with thc forked end 54 embracing this cam as shown` so that an cndwiscmorena-nt of the connecting rod toward the left of {"ig. 1 is cllcrted by thc rotation of the rain.

This sprocket chain has cani lugs 63 projecting therefrom at predetermined positions. Riding on the sprocket chain is one end of the bell crank lever (i4. suitably pivoted ou the frame ofthe machine. T he. other end of this bellcrank lever has the finger 85 pivoted thereon, the other end of which is in a position to be engaged andl lifted by any one of a series of pins (36 secured to the side of a ratchet Wheel G7, which is secured to the. shaft 48. The pins correspond`in position to the cam lugs (3 3. W ith this ratchet Wheel 'the dog- 68 is adapted to.

The pivoted gate 121 forms the control which determines which of the pairs of knit.- ting grooves is operative. l'Vhen the jacks are traveling from the direction indicated by arrow, the heels traveling iii the groove 119 will, if the gate he in the position shown in dotted. lines, strike'. the said gate and move it to the position shown iii full lines, thereafter traveling dowii around the ltnitting cani 120.- Vlhen, as occurs during' the periods of oscillating i'otai'y iiioveiiient, the Jacks travel alternately in opposite directions along the groove 119, the cani. is roi-lied from oneside to the other by the heel of the leading jack, so that pairs of knitting cains 120-122 and 121-,-123 hec-ome alternately operative.

The lower cani 'wall is also provided with a movable inclined cani 125, which is so placed that it inay he engaged by the heels of' jacks passing around the groove 118. This cani 125 movable radially to and from a position to engage the heels of iaclcs in a similar manner to the Canis 111 and 112 as hereinafter more particularly described,

The cainlfi is located in alineinent'with cani l 12 as the shifting oi' needles takes plaee at the saine position toward the back of the machine for either cylinder. The jack heels passing up the inclined cani 125 travel along the path 126 a sufficient distance t-o give the needles time to transfer. The heels then travel down the inclined plane 127, which nist-ores the jacks to their normal position alter transferring, with their heels in aline nient with the non-knitting groin@ 116 and pathway 17,

Before describing the manipulationof jacks and needles during the knitting of lli the 65.to'e and heel portions of the soclr, it will he well to describe the niethod of operation of will also he assumed that the sock of ay size to require sere two needles. The. cycle of operations starts with the oiie-aiid-one rib. '.lhis means that 36 needles are in the upper cylinder and 3G in the lower cylinder, the

arrangement bring alternate. see Fig. 25, foralternate needles of the 36 in `tlie upper cylinder are provided with long` heels, which are indicated by the reference nuiiieiral 95 (see Figs. 13 and The remaining' jai-lcs li, see lfig, 25, for one-half the rirrniiiference olfthe upper r.-'linder are provided with shorter upper heels indicated by the reference character 95". lThe jacks of needles for the rrniaiiiini,r one-half oi' the cylinder which alternate with the jacks carrying Ythe heels 95, are without upper heels at all, or heels too short to he engaged by the cani 112.

1f therefore when the cylinders are' in continuous rotation knitting the one-aiid-oiie rili, the cani 1l2'is pushed into the position shown in full lines inflfig. 13, the heels 95a will be engaged h v the cai'i'i and their jacks carried down 'to transfer the needles carried thereby to vthe lower cylinder as hereinbefore described. This results inalternate needles Yot the upper cylinder being transferred to the lower cylinder. leavingr eighteen needles iii the upper eylil'ider and giving fifty-four needles in the lower cylinder. This results iii the knitting of a three-andone ril). This knittingr goes on untilv the heel is reached.

The cani 112 is then pushed into the position shown in dotted lines in Fig. 13. This engages theI` upper heels 95" and results in all the remaining needles for one-half of the circuin'l'erence of the upper cvlinder being The jacks y,

transferred to the lower cylinder, making plain knitting for one-half the lcircumference of the sock, the three-andone rib being continued through the rei'nainder of the circui'iit'erence as nine needles a (see Fig. 25) st ill remain in the upper cylinder. The jacks which have been transferred remain in nonknitting position iin/til r stored-*oy the push of the opposite jacks when needles are being' rig-transferred. lhe turning of the heel now eoinn'iences as will be hereinafter described, the nine reiiiaiiiing heels in the upper cylinder being held out of action hy the withdrawal of thrcai'i'i 111. Burnier and after the turning of the heel, the position of the needles remains unchanged` nine only remaining in the upper cylinder, these being returned to action after the heel is turned by the can; 11.1 which is returned to normal position. when the toe is reached the turn- 5 down the groove of the cam 121.

in,"r again commences as hereinafter described, and, after turning, the cam 125 is pushed in sufiiciently tar to engage the heels of the jacks f and g, sec liig. 25, of the. lower cylinder, restoringthe necessary needles to the upper cylinder toenahle the knitting of a 'one-and-one ril to be commenced, after which the cycle off operations commences over again. As there is no need for a. selective. transfer of needles from the lower. cylinder to the npper, the heels 95 of the jacks of the lower cylinder otA needles which have to he transferrial may be all of the same length.

Turf/ling of Hu: heel mul 150e. The turning otv the heel and toe is effected hy means of the. following constructions2- Between the knitting cams 121 and 122i a dog 12h' is pivoted, the. end thereof being notched in such a way that no mat-ter what position shown in Fig. 18 the docY occupies` it will he. in a position to catch the heel of any jack traveling alonlgr the groove 113, assuming the dog;r to he pointed toward the direction in which the iai-l; is traveling. The dog rests'against the corne-rs of the blocks forming,r the grooves andcani paths as shown. i

()n reference particularly to Fig. '20, it will he seen that the pivot 15() ofthe dog,- 12S has a lng secured thereto. 'l`o this lugr is secured one end of acoil spring 152, the other end of which is vsecnri'id to a suitable stationary part. The point of' connection of the spring is so located lthat as the dog 12S rocks the coil spring1 crosses from one side to the other of the center of Athe. pivot so that the single spring will tend to yieldingl'yV hold the. dog 12H in either olf the positions shown in Fig. 1S.

Between the cams 120 and 121 a finger 129 is jonrnaled. This finger is provided with a forked end 13() of sufficient width to engage the heels of two adjacent jacks. This linger is so proportioned and located that when rocked from one sideto the other it will engage the lower heels of the two jacks and draw the jacks down sufliciently fa r to draw their upper heels down past the pivoted gate 124 vand down into the groove of the cam 120, assuming; the initial posi-tion to be that sho-wn -in full linesl in Fig. 18. lf the initial position he that shown in dotted lines, the movement is in the rever direction, and the upper heels of the jacks are carried Above the. gate 124 a gap 1?;1 is formed in the path 11T to permit of the heels of jacks passiincT from the groove, 1li) to the. path il? and vice versa. similar gap lili is formed in the dividing ril; between the grooves 11G and 11S to permit the passage of the lower heels from the groove to the groove 116 and .'ice versa.

'l`o the right of the knitti Lf cam ll will he secu a pivoted cam linger 135i which may be rocked up or down to move jacks from engagement with the non-*knitting grooves to the cam grooves and vice versa. During the. turning of the heel and toe, the knitting cylinders are oscillating and only one-,half ofthe needles of the lower cylinder are in operation. The remaining half must there fore be thrown out of operation. This is cficcted hy rocking the cam finger 133 to the position shown in dotted lilies in Fig. 1S.

'.lhe jacks for onehalf of the circumferv ence of the lower cylinder are provided with elongated upper heels 91 so that when the finger 133 is moved to the position shown in dotted lines, only the jacks carrying these elongated heels are raised to run on the nonknitting;r pathway 117, thel remainder, except as hereinafter described, continuing to rnn in the knitting grooves 118 and 11th A gap 121i. is 'formed in the rib separating the

grooves

116 and 118 imn'icdiately below the finger 133 to permit of the lower heels olf the jacks raised by the linger 133 passing from one groove to the other. iVhen the finger is raised to the elevated position, it will engage the elongated heels of the previously raised jacks and rex-transfer them to the knitting,r cam grooves. The means for etlecting` the movements of the cani finger 133 will be hereinafter descrihed,and ,also the means for actuating the finger 129. A guard 135 is located over the gap 131 to prevent jacks lifted bythe dog 19.8 fromV throwing: np too'far,"tlie l, upper heels'of these jacks engaging said guard.`

' The mode of operation of the'p'arts de scribed is as follows: During the continuons rotary movement of the cylinders, the jacks move in the direction indicated by theJ an row, the gate 121 being in the position shown in fnll lines and the dog' 128 in the position shown in dotted lines. The heels of each jack then pass along the grooves 11Sy and 11S). The cams 120 and 122 arcnthen active in knitting.

As soon as the oscillatingr rotary move ment begins` all the knitting is done in the lower cylinder and all the needles in the upper cylinder must thenv be idle. To effect this the cam 111 is withdrawn so that the heels of the upper needles a (Fig. 13) are no longer directed up to the groove 108, lint are alloivedto travel in. the groove 10G, which maintainsthem idle. The pivoted cam linger 1355 is at the same time operated to throw the. needles of one-half of the circumference of the lower cylinder into inoperative position. The heels of the jacks and needles c and y] 2(3) remaining in the lower cylinder then reciprocate in the grooves 11S and 119. lll-ach time. however, a change in the direction of movement takes place. the heel of the first jack or needle traveling in the groove 11S is engaged hy the dog 12S which automatically rocks upward Under the pressure exerted by the heel. and thus raises the jack or needle sulliciently high to briner the lower heel intoa 'position to travel in the groove 11o while the upper heel is lifted past the grate 124 to ride in the pathway 117.

Assuming the original position of the dog to be that shown in full lines in Fig. 1H, it

non' drops over to the position shown in dotted lines readvto catch the heel of the Al'irst jack or needle which reaches it after the direction of movement of the jacks has changed. The end needles of those which areknittin,r the heel are thus thrown ont of. action one byone. 1t will benoted of eonrse that the gate 124 alternately changes its position as contacted by jack` heels so that the gap for the passage of the upper heelsof jacks raised by the dog' 128 is always in the right position. `When the wheel is half turned, about halt a dozen needles are still knitting. 1t is now necessary1 to complete the turning of the heel, to begin to throw the needles into action again until the needles for one-halt of the full circumference of the lower cylinder are again knitting. r1`his is effected by means of the tinger 129. Y v- Assinning the finger to bein the position shown in full lines in Fig. L8, thejacks are traveling in tl'ie'directmn indicated by the arrow. As soon as the leading two jacks lia-ving their lower heels .running inlthe groove 11G` reach the proper position, they eng-aigle the il'iger 12.) which has been rocked .by

path, and the two jacks continue the rocl ing.)r and are moved down by the finger. The gated 124 will then be in the position shown .in full-lines, and the upper heels, as the jacks are forced down by the finger 129, will be engaged by the lnder. side ofthe gate andl travetdown past the gate and down the cam 1?()1 while tlie.tingex"129 swings into the position shown in dotted lines.

l'1t will be I ioted that the linger 12S has heen previously rocked to the position shown in dotted lines by its engagement with the first of the jacks still iu thel knitting position1 so that it' lies in` the path of the lower heels of Vjacks being moved down to a'knitting' posit-ion by the combined action of the fiiiger 129 and the Vfate 12%A A notch 1-.l is therefore formed in the side of this dog, see particularly Fig: l), which permits of the passage of the 'neel down past the knitjv ting cam 122. The result of this arrange mentis that during each movementof the knittingcylinders in either direction. one needle thrown out of action and two brought into action, a gain of one thus being made at each movement. This 4gain een tinnes until all the needles are again in ac tion, 'when the movement of the linger 129 'neans hereinafter described into their `along the line of the turn.

Alter the tnrniner of the heel or toe portion the continuons rotary movement of the Cylinders recommences with all the needles in action, thc cam 111 'and the camlingcr 1335 being:r moved. .'as herr-.inbefore set ont, torestore the needles' to their proper kuit-ting` positions for the foot after the heel is turned and for the cutlj' after the toc is turned.

(faul-rol mcclumwismfor 11u/:wolf: www (rml are shown particularly in Figs. 3, 4, and l-l.- The cam projections 1257 on the drinn t7 serve to actuate the lever 138 .fulcrnmed on` vthe spindle 57 (seejmrticnlarly Fig. 2).

'l`he other end of this lever is so positionedv that it may engage and push the projection 13S) on the ring H0, thus turning the' ring slightly to the rig-ghi in Figa. On this'ring 14') is pivoted the rocking pin 141 which is yieldingly held so thatI it projects radially by means of two -coil springs 142 connected to opposite sides of the rocking p'inia-nd the ring 140. Normally this pin is out of the. path of a cam projection 14.34 secured to the verticall shaftt. 1V hen, however, the ring is pushed to the right,'the pin' comes' into" the. path of the earn projection 143 so thatv 'I thea-ing will be -inoved each time the' cani-V projection oscillates from one side to the other as it does during the oscillating knitting movements ofthe cylinders. The ringgr is thnsrgiven a short oscillatingrotary move-v ment, the' amount of which is determined by one of the two stops 144 lconnected to the top of the frame of the machine and extending into the path of the projection 145 on the ring and by the projection T13-S) cngaging the endof the lever 138.

When the movementof the ringl is stopped by the projection 1-15 engaging one ofthe Stops 144. the cam projection 143 slips b v the rocking pin 14d7 which7 as before stated, if: only yieldingly held by the springs 142. '1`he cam projectionthus passes by the piu and is 'positioned to engage it on theopposite side .for theretnrn movement. A

When 'oscillatingr rotary movement of the knitting cylinder ceases. the cam projeciion 137 releases the lever' 133 so that the ring will be moved sutliciently far by the last oscillating movement of the cam projection 143 to clear. the path of the cam projection, the other stop 141 limiting the movenientj and the cani projection thereafter r0- tates contixiuonsly without contacting with the rockinglpin 1.41. It will be noted that the projection has a. cavity formeiL there' in which engages the lower end of the. rawhing arm 1467 which actuates the roi' zing: fitr ger 129, see Figs. l and Q0. This` roelt ai iii 146 is loosely journaleol on the pivot of the finger 12) andfon the pivot of the linger itin is secured a lug 147. The arm llo has two projections 148 formed thereon.y one at each side, of the lug 147 and spared therefrom. .i coil spring 149 is secured to the luf: l i7 anti to thel arm 146, so that as the finger 122i rorltffrom one Side to the other the mil spring; will cross from one side to the other of the center on which they finger rocks. From this: construction it follows that when the. rock arm 146 is moved to the left, having' reference to Fig. 20, the left hand projertion 148 will engage, the lug! 117 to push the latter to the right to move the finger 129 into 'the path of the heels of the jacks :is hereiiiliefore described. The jacks continue the movement of the linger until the spring; 145i Crosses the center. when the tension of the spring will snap the lug` 147 and with it the linger 129 to the limit of its motion to the right :intl therefore to a position in which when the rorhY arm 14-(3 is nioi'eil iii the reverse diret-.tion the lug 147 will he engaged hy the right haiiil projection llt? :intl the reverse movement started to he rouln'iieii by the` heels of the jat'lis until the spring again crosses hach past they renter and the luy; 147 and linger 129 are snapped 'haelt to the left.
