nod to show the draw and raise as will be hereinafter described, and pointed out in the cleims- I propose first to describe my improved transfer (Figs/t-Afimnd at) by means of which the tops of the stockings which 'nre knit in another mechine, are transferred-to the needles of my mnehine, preparatory to starting the some.

lily-invention relates to automatic machines ner end ota raise-cam slide which fits into a guideway formed to receive it in the cen-' ter of what I term a cam-box, or housing J which is secured to a table J", offsetting from the bed F, of the needledial G. The said slide is provided with a depending studj, which passes through an elongated slot formed in the bottom of the box 3 parallel with the length of the said slide, and enters to a cam-slot K, extending at about a right? an gle to the slot y'i and formed in anopcrating slide ii." mounted in the said box, so as to extend transversely under the cam, and having one of its ends turned up as at K for convenience in operating it. By means of this operatingslide, the @ll-ll'l-SlltlO and hence the cams, are moved inward as shown by broken lines in Fig.1 toeause the needles-to move inward, and take the yarn, and are only :.inev ed outward as shown in full lines in said figure and thus retired when it is desired to transfer cult' to the needles. The said broken lines show the normal or knitting positions of the said cams.

2 The needle-dial G, before mentioned, is constrncted with acircularseries of radial grooves i formed in its upper face, and extending from its outer edge through a raised shoulder, located close to its inner edge. These grooves 0 receive the needles Ii, all of which are of the same length, and constructed at their outer ends with upwardly turned butts 7b. The outer edge of the dial is provided with antannular groove G, (Fig. 7) in which, as herein shown, a cord G (Fig. 4) is placed, for bold-- ing the needles against outward d isplacement under the action of centrifugal force. When,

however, it isdcsired to remove a needle, that may be readily done by solving its butt and ,0 drawingitoutward against thecord,whichwill spring out of the way, and allow the needle to pass over it. The innerends of the needles rest upon the depressed annular seatrg formed within theishoulder g, as shown by Figs. 7 and. 7. The lower face of the dial (Fig, 7 and ll is constructed withconccntricribs G G, the latter having a bevel gear tx formed upon it. The rib G has a circular series of radially arranged grooves gflformcd 5c in it, and the rib G" a correspondingseries of aligned grooves f, which extend above the bevel gear aforesaid. The inner ends of the grooves g merge in a corresponding series of v'crtic .13 arranged grooves formed in the inner edge of the dial. The said grooves 7 g and Q" located in'the lower face of the dial, re alternated with the grooves ii, formed in the upper faces thereof, and receive the sinle crs M, which are securcdin place by washers in, applied over the grooves 9 in the rib G and held in place by screws in entering the dial lie-twee the said grooves g3. Each washer holds two sinltcrs in place. The inner ends of these sinlrcrs, which are bent upward at a right; angle, and then. turned inward to torn: hooks, play ;up and down in the vertical grooves '9 formed in the inner offices which the running of such a machine often demands.

The sinker-s M are actuated. in the upward movement by means of laterally adjustable sinker-cams M. M (Figs. 1t and 4) having wcdgcshapci'l uppercnds which form operating-faces with which the sinkersare engaged, as the dial G, rotates, at points just within their upwardly bent inner-ends. As thesinkers ride up over the cams, they aroliftcd, re-

turning to place again by theirownrcsilicncc as soon as they are carried oil the cams. The said cams are secured each bytwo screws M to the opposite edges M, ofa vertically ad justable bowed canrplato Al the said edges being thereto constructed with laterally clongated slots at, through which the said screws pass, and which permit the cams to be laterally adj ustcr'. The said cam-plate has a long downward extension M terminating at its lower end in a short rod M which is seated in a block M", carried by a bolt M ,.(seo also Figs. 1 and 5) which is vertically adjustable in a vertical slot M formed in the lower end of a hanger 1, depending from tho dial-bcd i The cams and upper end of the said camplate areheld in place against lateral movement by the conliucmcntof thecams-bctwecn IOC that portion otthe wall of the central circular opening in the\diall)cd F, which is adjacent to them, and a fender m (Fig. 11) segmental in form, and secured to the dial-bed F in position to engage with the inner faces of the cams. .The edgewise movementof the said cams and plate is prevented by two adjustable segmental blocks m m, secured to the under face of the dial-bed I in position to s'ecured, and by moving them-upon the said plate. The said sinker-cams are employed by me for relieving the strain on the stitches while the noodles carrying the same are passi'ng outside of the drz'iw-cams on their Way to the raise-cams, which move them inward to cast the said stitches back over their latches, for instead of employing switch-cams to cause the needles to pass inside of the draw-cam,

which is not knitting, and thus avoid straining the stitches outho needles, I invariably pass the needles on the outside of the said drawcam, and by means of the sinker-cam not knitting, allow all the stitches themselves to rise enough to makeup for-the outward movement of the needles as they pass on the ontsideof the draw-cam. Thus when the machine is doing straight work, and thedial working, the rear sinker-cam will raise the sinkers to assist in forming the stitches which are drown through the old stitchcs by the rear draw-cam. At

this same time, the forward sinker-cam will raise the 'sinkers to let the stitches on the Yneedles lift enough to permit the needles to pass on the outside offthe forward drmwca'm without straining the stitches. lVhemon the other bend, the machine is doing heel and toe work, and the dial oscillating-the sinker-cams will operate to relieve the stitches which they.

themselves formed, Thus, supposing the dial is moving from left to right, then the rear sinker-com and the renrdrnW-cani will'assist in forming stitches. Then when the dial swings buck, the needles carrying those same stitches will be obliged to pass on the outside of the same renr drew-cairn, the some sinkercom operhting nl'. this time to liftfthe' stitches so as to permit the needles to be moved ontword by the said drnw cnm.without straining the stitches. At the same time that the dial is swinging back from right to left, and while the rear sinker-cairn is operating as described to prevent the stitches just formed from be ing strained, the forward draw-coinandfthe ihe stitches, whereby I greatly simplify the construction and operation of my machine.

A detachable ring" or annulus N (Figs. 3, 4, 5, nndfi) set into the upper face of the dial, is constructed with nncup'wardly extending semi-circular flange it ',which on account of its function, I. shall hereinafter speak of as the putting-up flange; This flange is'procided at one end with an clcvnt'cd step N the funciion of which .will be described at another time. The said dial is actnntedin rotary and oscillatory movement by means of n bevelgcnr 0, (Figs. 1,5,6, and 8,) meshing into its bevel teeth G, and mounted on n horizontal driven shaft 0 the opposite'ends whereof have hearings in hangers-P and P respectively depending from the dial-bed F, and the arm or table J otlsetting therefrom. A gear-wheel 0 mounted on the said; shaft, and placed directly against the bevel gear wheel 0, meshes into a. pinion 0, (Figs: 6 and 2) mounted on the inner end of a. henzontnl driven shaft Q, supported in bearings formed. at the opposite ends of n. brnclrot Q, (Fig. llbolted to the l'ront of the upright position.

standard in, of the machine. The opifaite end of the snid shaft Q, is proyidedw i two loose pulleys-ge and n fixed pulley q lo cated betwcenthe same. These pulleys receive two oppositely running (one being twisted) driven belts, which are not shown f but which run were driving nlley S, located at the outer end of the horizontal driving shaft S, mounted in bearings S S4, (Fig. 9) secured to theback of the said standard 3, near the hose thereof, and provided'at its opposite end with two loose pulleys s s, and a fixed p'nlley s, located between the same, the said pulleys s, s and s'fi-receivinga fast driving-belt, which is shifted back and forth between the loose pulleys, and the fixed pulley s endnslow driving belt, which is shifted between the loose pulley s, and the said fixed pulleys", both oi the said beltsbeing driven.

from nny"'con,venient source of power,and

both being connected with and shifted by the lower end of the belt-shitting lever which thereto is constructed with a. double fork. The said lever 75 is hung ilpon a. horizontal stud '75", projectingrcnrwnrdly from the bracket :32, which nleo carries the lever 522 as before set forth, the upper end being arranged to engage with the lugs 73 and 75 of the prinmry pattern-wheel 25. The said fast and slow driylnfl' belts form the main driving belts of the mnchinc,..nnd theirrespective functions are to drive the machine rapidly when thedinl is rotating for doing streight' work, end to drive it'slowly whenthe dial is oscillating for doing the heel and toe WOl'k, all as will nppear'lator' on. r

The yarn is fed to the needles by means of an annular yarn feed '1, (Figs. 1, 2, 3 and 4) rigidly secured to the lower face of the inner end of a pivotal curved arm '1", the curved outer-end of whichis hung on a. horizontal pin t, mounted in a box t, bolted to the top of the stnndnrd R, and extending at its inner end over thedial. The rear 01:3. of this box is occupied by n plunger "1", the inner end of which abuts against the curved outer end of the said pivotal arm T, the said plungerbeing constantly urged against the said. endof the nrm by means-of n 'spring- T, (Fig. 4,)

whereby the feed is maintained in its normal horizontal position, or in its retired vertical By. melting the feed annular in form, it is easily manipulated, es the attendnot. one pot a finger intoit encl' lift it up, acid in the some may draw it downinto place. Its outer edge is beyelerhnszrttf, and constructed on one side with a beveled wedge-shaped off-. 7

set i", containing an eye i through which the yarn passes, the said offset being in line,.wheu

the yarn-feed is in its normaLor operating position, with ihenniversal cam V, yet tobe described.

By beyoling the edge of the you'll-feed, the yarn bllztliifi not lrnit up when thc machine is on heel rind toe work, rides up the sold. berclcd ed ct-nine than: it in renrl'ilytnken up by the tnlrenp, whereby l nroid the cunt-ling of the slack yarn in the latches-of the needles, and insure its being taken up. Furthermore by beveling the edge of the yarn'feed I avoid the breakage of needles, for if their latches did not have that clearance, they would sometimes engage with the edge of .the fe'ed and break.

The draw-camsU U (Figs; 3 and 7) of the machine are located on opposite sides of the raise-cams J J, and theuniversal cam V, and secured to the lower faces of the inner ends of fiat draw-cam slides U U by means of which they are supported in fixedpositions over the edge of-the upper face of the dial in the paths of the butts of the needles II, the said slides being located in guidewvays U formed for them in the cam-box before mentioned, which is su pported upon the table J oifsetting from the dial-bed l Plates or covers U U applied to the ends of the box over the said guide-ways, confine the slides U U therein, the saidplates being respectively secured in position by bolts U* U, and two pins-u 10 located on opposite sides ofeach bolt. The draw-cams are readilyadjnstcd with reference to their exterior-over the needie-dial, for regulating the tension of the mesh of the fabric being knitted, by means of setscrews u u, (Fig.10) extending parallel with the slides U U and respectively entered into the opposite end of the box J from the outer edge thereof, each of the said set-screws being provided witha collar 11. which takes into a transverse groove n formed in'ithe under face of the outer end of the slide above it, whereby the slide is coupled tothe screw, and will move back and forth with the same. V The outer end of each screw is furnished with a notched wheel to, the notcheswhereof receive a spring 14, whereby the screw, and hence the slide, are finedin position. It will be clear that by burning the screws, the slides may be moved so as to change the positions of the draw-camswith respect to their extension over the needledial, which'moves under them. Each of the draw-cams U U, is furnished with a guardu (Figs. 3, 7 and 10*) consisting of a button adjustably attached by a screw u? to a small finger u extending inward from the inner edge of the earn, the function of the said guards being to put down any needles that may be thrown too far inward, into position to be engaged by the faces c n of the uni-. versal cam which puts them down into'the knitting path.

A cam V, (Figs. 3, 31-3 2, 3 and which, from the work it performs of pnt-tingnp and putting-down the needles,Ish-all call the universal cam, is located between the draw-cams and centrally above the raise-cams, projecting inward beyond the same. The inner edges of the said raise-cams (Figs. 7 and 10") are cut away as at 1' 7' to give clearance to the said universal cam when the same is drawn outward, the raise-cam slide J being also cutaway asat j, for the same purpose.

This universal cam V, has the inner edge of its lower face cut away as at r 2*, to form downwardly inclined converging run-waysior the butts of the needles, and its correspondouter edge correspondingly cut away, to form downwardly inclined converging runways v 1-, whereby its lower face isgiven a convex diamond shape or what may beso described. The cam is provided in the center of its upper face, with a short shank V, (Figs. 3 and 23) by means of which it is held in place by a set-screw V in a vertical socket formed to receive the said shank, in a head \V, of a bar W hung at the outer end on a horizontal pivot. it, within the chamberX, of the sliding carriage X, which is moved back and forth in the earn-box J", in which it is located between the'draw-cam slides, and over the raise-cam slide J? A horizontal sheetnneinl sprin er, secured. at its outer end to the outer end of the said carriage, extends inward, and is bent downward at its inner end, to engage, (Fig.- 5) with the upper end otthehead W, of the pivotal bar W, whereby the said cam V,-is steadied, and prevented from jumping upward under the iinpingement of. the butts of the needles against it. The mechanism for-sliding the carriage X hack and to: 31, and for raising and lowering the cam V, will be described later on. The

-UlllVGlS2il cam V, just described, performs the work of putting upand putting down the needles, one at a time, operating upon theni, as it might be said, individually. The work of collectively puttingup the ncedlespreparatory to heel and toe work, is done by the putting-up flange N, and its elevated step N (Figs. 3 and 3 before referred to, in combination with a pivotal spring-actuated putting-up lever Y, (Figs. 1, 2, 3 and 8) located at the back of the machine, and extending forward over the dial, the said lever being provided at its inner end with a finger Y, which. co-operates with'the said flange ix" and step N and with a putting-up cam Y which extends downward into the path ot the needles to which it is inclined at an angle, and which consists in fact of a plate of hardened metal. 'lhesaid lever is mounted to rock on a horizontal screw-stnd y, entered into a bracket 1 screwed to the upper end of the standard ltofthe machine. The outer end of this lever is tapering in form, and has its upper and lower faces slightly beveled for cooperation with the upper end of a stifi spring Z, which is thereto shaped to form the retaining shoulder. and. ,the inclined opcrating-face z. The said outer end of the lever is also provided with an inwardly projecting, horizontal trippingpin 3 which co acts with a tripping spring Z, arranged par allel with the spring Z, and havingits upper end constructed with aclearancc notch 2' Fig,

3, and an inclined operating face 2 The means employed for supplying yarn to the yarn-feed 'l, bel'ore described, will not be set forth in detaihfurther than is necessary to the description of the devices used to feed The notches 37, before mentioned of and the deep notches 37, of the secondary pat tern Wheel 27, which is moved through the distance represented by one tooth by every movement of the pawl. The notches of the said pattern wheel are, however, so shah iow that they do not permitthe maincd 'e 34, of the pawl to drop into the notches 20 (Fig. 10), of the primary pattern wheel 25.

the secondarypattern-wheel, are deep enough to permit the pawl to fall inward suiiitiently for the engagement of its main surface 34, with any of the notches-25", of the primary patternwheel, which will therefore be actuated with the secondary pattern wheel every time one of. the deep notches 37 of the lat-tcris brought under the pawl. Each notch of the secondary pattern-wheel, of whatever depth, represents a single course of knitting, enc pt when the machine is turning the heel and forming the toe, when each notch represents two courses of knitting for the said wheel is moved through the distance represented by one notch every time the needle-dial makes a complete both of the-wheels revolution and knits one course of stitches, in Straight knitting, whileon the other-hand, the wheel is moved only through the distance ropresented by onenot'ch for a movement of the dial forward and back in ting, both of the said movements of thedial forming a course of stitches. 'lhe said deep notches, 37, it will be noticed, are arranged at equal intervals apart, and virtually d ividc the wheel 27 up into, blocks, each of an equal number of notches, which, in the machine showmare of nincnotches eacinbntthat number may of course be varied according to the character of the work to be done. Underthearran'gcmcnt shown, the primary pattorn wheel 25 would be actuated for changing the pattern, only between intervals of nine courses of straight knitting, or eighteen courses of heel or too knitting. It is often desirable, however, in order to make the stocking of the right form, to move the pattern-wheel oftencr than this, and to provide forthat requirement,I furnish the secondary patterirwheel with the-medium or intermediate notches 36, which in every case -arolocated adjaccntto the-deep notches 3. These intermediate notches, however, are not deep enough to allow the pawl to fall inward-suiticiently far to engage its main edge 34, with the notches 25 of the primary wheel, unless the tceth'bctween same are built up, so to speak by little blocks 39 (Fig. 10) which are screwed to the teeth of the primary patternwheel, whereby some of the notches thereof are made virtually deeper than others. hose little blocks may obviously be shifted around as desired. Now when the pawl drops into one of the intermediate notches 36 in the sec ondary pattern-whoel 27, the said notch being at that time in alignment with abnilt up notch of the primary pattern-wheel 25, then will be moved together, whereby the primary pattern-wheel is given cause the intermediate notches heel and toe knitfore been described, is oper t'tied by an additional movement. it will be noted that this additional movement of the primary pattern-wheel must always immediately precede its regular and unii'orm movement, be-

pattern-wheel with the intermediate notches 36, and the use of blocks 39 for building up some teeth or the primary pattern-wheel, I am enabled to modify the operation of the primary pattern-wheel as the particular work to be done may require. The pawl 31 is also provided with a vertically adjustable finger -10, (Fig. 2.) made somewhat longer than its ling er 3i, and arranged to cooperate with the auxiliary tooth 4-1 of the primary patternwhecl. The said auxiliary tooth 41 (Figs. 6, l0 and 10) projects at its outer end, which is bent at a right angle to its main-portion, through a segmental slot 42, formed in the primary pattern-wheel 25, its inner end being extended nearly to the center of the said whet-l, and hung on a horizontal screw-stud 1L3. A bowed spring e l, passed between the inner end of the tooth and the said'wheei, frictionally holds it against displacement. The outer end of the said tooth, which is engaged by the adjustable linger it) of the pawl, is constructed with a small log 45, which is also engaged by the said finger, whereby the auxiliary tooth is "drawn forward out of the way, so that it will not be in position to cooperatewith thesaid finger of the pawl the next time the pawl is operated. The said tooth is restored again into its opera-live position by its engagement with the inner end of the lever :32, which, as i 2t of the pattern-wheel which in turn controls the operation of the put-tingup lover and the introd notion and out ting cit of the reinforce thread. understood that the auxiliary tooth, by comuuder the adjustable linger 40 of the on crating pawl 31, prevents the same from drop.-

The said aux." iliary tooth il, is employed to avoid the formation in the heel of small openings at points therein where the regular-or full courses of the knitting end, and begin again, or in other words, where the narrowing for the heel hegins and the widening therefor ends. 1 avoid forming an opening at the points described, by an arrangement under which all the neel-dles used in knitting the first course of the heel are not used in knitting the last course thereof. it the first and last courses of the heel were knitted by the same needles, the

I ovoirl finishing the heel proper with the neo dies by which it was begun, by means of the auxiliary tooth ll which by cooperating with iheerljnstable tooth 40, of the operating pawl, prevents the some from felling into a notch of the secondary.pattern-wheel, which is thus temporarily out ontof operation, entl'uiisses one movement, and as in inheheel and toe work one movement of the secondary petteruwheel represents two courses of stitches, it will he apparent) that when the primary pattern-wheelgeins one notch. upon the eccomL cry pattern-wheel, the machine will. knit two more eohrses of stitches time it otherwise would, before the pattern is changed by the These tlwo extra'conrses ofsmitches belong; to the narrowing courses of stitches in the heel. These two extra courses are, however, left out of the wideningiccurses of the heel, so thei the machine does not, in colnpietingthehecl, go back, so to speek eucl finish the some on the needles which lmittedi is first two courses,

but stops just short of the said needles, and

. is finishedhythe needles next to them. The

two courses of stitches knitted hy the needles which began the heel,.will;not therefore be duplicated, in finishing the heel, by the seine needles, forjf sothen there would be four etitches opposite eaclroiher, uniting to form the holes referred to, but by failing to use the, needles which hogan the heel, in finishing itR point may he better understood by illnstrw tration'. Suppose, for instance, that there are thirty-eight nerrowing'eonrses in the heel, the thirty-seventh and thirty-eighth courses thereof being added to the number lay means ofvtlie auxiliary. tooth which causes the scccutlery pattern-wheel to ski 1) one movement.

If there were thirty-eight; narrowing courses in the'heel, there would he only thirty-six widening courses. ,Itwill he econ from this that in finishing the heel, the machine lllil not return to the needles which knitted the.

first and second; of the narrowing courses, for otherwise there would hove been two more widening courses, namely, thirty-seven end thirty-eight.

said ribs, the said openings being thereto presented to the finger by the rotation of the primary pattern-wheel. The ribs 66 are extended into the openings 67 and (3-8 by means of segmental blocks 6.9, (Fig. 10) which are located opposite each other, one being virthe other an extension of the opposite end of the other ,rib. Each of these blocks has its outer endcut away below the level of the ribs to form a long step 70, and a shoulder '71, the

said step and shoulder of each of the blocks 69, co-operating with the finger (3% of the le Ver 47in producing the particular movements of the cam-plate 46 as will be described at another time.

The means by which the operation of the putting-upleverYis controlled from the pattern wheels, have already been described, and will not receive further attention "more than to mention.=.that they comprise the lug 24, formedon the face of the primary pattern-wheel 2 5, the horizontal lever22, and the vertical slide 3, and the spring 26 thereof.

For the function of the pattern-wheels in stopping the rotary movement of the needledial and causingitto oscillate, and then stop ping its oscillating movement and causing it to rotate again, and for changing the speed of the machine from fast to slow and from slow to fast according as it is being run on straight work or on heel and toe work, the primary pattern-wheel is provided uponits exposed face with four lugs 72, '73, 74 and 75 (Fig. 10) arranged quartering with each other, and varied in character to produce the redescribed. Of these lugs 73 and 75 cooperate with the upper end of the beltshifting lever 25*- before describec whereby they cause the speed of the machine to be changed as required. 'lhelugs 72 and 74 are, in the rotation of the pattern-wheels, engaged by a finger 76 projecting outward from a horizon-v tal lifting lever 77, (Figs. 3, ii, and 8) hung for movement in a vertical plane on a screw-stud 78, mounted in a horizontally adjustable hearing 79, attached by a bolt 8dto the rear arm 29, of the bracket 29 (Fig. 11') which is bolted to the frontof the standard R, the said arm {being constructed with an open slot 81, in which the said'stud 80 removable. The said lifting-lever 77 is provided at its extreme forward end with an inwarlllly projecting lifting-arm 82 (Fig. 6) whic enters a transverse notch 83, formed to receive it in the rear face of the lower end of the sleeve 84. of the shifting-lever 85, which swings-in a horizontal plane on a long vertical stud 86, adjustably mounted in an open slot 87, (Fig. 11) formed in the forward arm 29 of the bracket 29. The rear end of the shifting levcr is provided with a depending pin 88 (Fig. 6) which plays in an elongated slot 89, formed in the rear end of a coupling-head 90, which gitudinally movable shifting-rod 30, which at l its opposite end carries the belt-shippers- 91 and 92 (Fig. 1) by which the oppositely running driven belts are shifted upon the pulleys q q for edge 93, (l igsli and 8) which enters a transverse slot Ell, formed in an enlargement '95 of the lower end of the vertical stud 86, on which the said shifting-lever swings as a sea ter, the said coupling-head being thus steadied in its lateral reciprocations. The said shifting-lever is provided upon its forward end with an upwardly projecting lug 96, (Fig. 5) which is engaged by a cam 97, secured to the driven-shaft 0, between the eccentric 33 V of the operating-pawl 3i, and the gear wheel 0 The said cam 97 is constructed to engage with the opposite faces of the stud 96, so as to swing the lever 85 back'and forth in a horizontalplane, whereby the helt-shlfting rod 30,

I The forward end of the said coup-' ling-head 90, is constructed to form a flat leaf will he correspondingly moved by its connection with th s shifting-lever through the pin 88, and coupling-head 90. The said cam has two flanges located about opposite each other and corresponding to each other except in their arrangement, which is reversed,the faces of the said flanges being alternately engaged with the stud 96 of the lever 85 which is thus swung back and forth. The shifting-lever will not, however, be actuated as described, except when it is vertically supported in position for its lug 98 to he engaged. by the cam 92?, anditwill not be supported in such position except when the log 76 of the lifting le ver 77 iii-engaged with one of the liftinglugs 7.2, or 74; carried upon the exposed face of the primary pattern-wheel As Seen as any one of the said lifting lugs passes beyond the lug '76,'tho shifting-lever and the lifting-lever T7Ywili drop by gravity into their retired positions, so that the cam 97 rotates without effect, but when the leveris lifted and oscillated as described, the belt-shifting rod 30, will shift the oppositely running driven .belts on the pulleys q q and 22, so to constantly reverse the rotation of the driven shaft 0, and thus cause the oscillation of the.

needle-dial. As the liftinglngs on the primary pattern-wheel operate the lifting-lever, and hence the shiftingdeverautomatically, the transition from rotary to oscillating movement in the diahand vice-"verse, is accomplished without interference with. the ma chine on the part of the attendant. The au-- ton'iatic stopping of the machine when the stocking has been completed, is also'ellfected through the pattern-wheels by the provision of the primary pattern-wheel with an in. wardly projecting stoppin 98, (Figs. 1, 5, and 10) which engages with the lower end of a stop-lever 99, hung on a horizontal bolt 100,

mounted in the lower end oi the hanger P. A spring 101, (Figs. 1' and attached at its upper end to a block 102, carried by the said bolt 100, engages at its lower end with the primary pattern-wheel, and prevents a retrograde movement thereof, without interfering
