acters on the drawings representing like parts.

, This invention has for its ob ect to im-.

prove and simplify the construction of the various parts of a circular-knitting. machine adapted for circular and reciprocating knit? ting. In this class of machine as now made;

the thread-carrier when reciprocating knitting is bein. done for narrowing and compleas in the production of tockings, has imparted to it a uniform throw, saidthi'ow being for a distance of more than one-half of the circum-- n cntal 'wi( eiiing,

ference of the machine, andhence during recipro-cating knitting a take-up has to be. employed, said take-up being automatically or otherwise thrown into Working position'tov control'the slack thread between the end niost needles used in reciprocating knitting and the stoppingioint of the thread-carrier, and the length oi this slack thread which must be taken care of varies continually during reciprocating knittin ()ne art of this invention -therefore,conipreheni is devices to stop the thread-guide during reciprocating knittin at or opposite the last nee e fed by the thread-guide in its reciprocating stroke, and consequently no slack thread 18 made, and therefore a take-up and its actuatingmechanisin, always more or less complicated and delicate in operation, become unnecessary.

In my invention the thread -guide is stopped close to the needle last fed by it in circular knitting, and as said needle is the first one to be fed for reciprqcatin knitting it will be readily understood that t unnecessary slack tread, and the thread is delivered constantly to the needles throughout I substantially reciprocating knitting under the same conditions and a erfectly made heel is insured, and so, also, y dispensing with the take-up yarns of less strength may be safely used in the machine.

The machine which I have chosen herein to illustrate my invention is of that class wherein when the change from circular to reciprocatin knitting is to take place the points or switches of the knitting-cams are so changed be used therein are ere is no in their ositions asto actuate t e needles whic are not to be used in reciprocating knitting, the said cams engaging and depressing the first of the series of pass under and not needles to be used for the reciprocating coursethen to be knitted, the number of needles so depressed being more orless, accorde'ngth of the-course. Tlie-needles' ing to the of any reeiproeatin course having been called into operation an having been moved to knitin that course are then all returned into the massiof needles, and for the next reciprocating course only the number of needles to depressed, and they are a ain returned into pgsition with all the nee- (1 es. Machines of t s general type are represented in an earlier patent, No; 453,059, granted to me on the 26th day of May, 1891, and also'in a patent, No, 479,986," da'ted- August'2,1892, said latter patent being-anv improvement on the former one.

he points or switches of the knittingcams occupy one position for circular knitting, and when reclprocating knitting is to be done said points are lowered wbetween two needles in the s ace at the junction of the non-knitting am the knittin groove, one of said needles being in the itting-groove immediately under the point, the lowered point being thus put into position to allow the next needle tothe one under its point,

and those following it while said point is depressed to ass over said point and continue in the nonnittin groove, and by the time that the last nee e to pass under the said point into the knittin -groove arrives in the non-knitting groove the first needle to pass over said point follows it in line in the nonknitting groove. Putting all the needles in the non-knitting groove during the last stroke for circular work leaves the needles in position to commence reciprocating knitting for narrowing and widenin and to do this the actuating mechanism of t e cam-ringis changed so that its reci rocating motion commences, and in this f st reciprocating stroke the points are raised at just the proper time between two needles, as stated, so as to enga e the butt of the first needleto be used for knitting in the reciprocating course said points remaining in such condition until it hastaken" from the non-knitting groove enough needles, more or less, for that reciprocating course, said needles so taken from the non-knitting groove bein run through the knittinggroove, and t en the points are immediate I ferred to is for convenience and adjustment of the position of the said stitch- 'from the needle-su porting bed or cone.

novel means by which to automatically con- 2 sas es again lowered between two needles, as stated, ing reciprocating and circular knitting; but which prevents the taking of any more neeits pawls are so controlled that they may he dles than those actuall needed from the nonput into and out of operative position. The knitting groove, and t is motion of the camawl-carrier is actuated from a cam carried ring is continued until all the needles put into liy a slow-moving shaft, (the shaft which conthe knitting-groove have arrived again in the trols) the reciprocating motions of the manon-knitting roove. This operation is rechine,) the machine when circular knitting is peated for each reciprocating course until the being done being run at a higher speed, as narrowing and widening has been e'llected. commonly practiced in machines of this type. To automatically move these points or t The tlu'ead-carrier is also a latch-guard, switches, I employ a toe-cam having an osciland its hollow central hub is embraced lriclatingmovement abouta fulcrum'orpin and a tionall by a ring located centrally over the vertical movement on said pin toward and conical bedin which the needles are reclpro cated. This hub may be and is herein shown as so supported that it may he turned The pin on which t to toe-cam turns forms part of what may be designated as the-camup away from t 1e frame of the machine and ring of the machine, said toe-cam when in from above the latches of the needles to enits lowered position nearest the needle-bed l able the use of a transferrer and the applicabeing adapted to meet and be turned in one tion of work to the needles, or'it may be and then 111 an opposite direction by suitable turned down into working position, so as to lugs carried by rings which have only a tocover and protect the hooks and latches oi and-fro movement intermittingly. in a circuthe operating-needles. This huh has a suitlar path, said toe-cam having a slotted arm able arm or arms which may be struck by a which directly engages a stud connected to ta'ppet or rojection moving with the camand extended upwardly from a plate fitted to rin and t )iS latter tap et is under the conslide transversely in a guideway formed in tro of a suitable eamw ereby its acting end the outside of the cam-ring.

Fig. 4 is adetail chiefly to show the devices for putting into and out of operative position the toe-cam and also to start the lever employed to move the thread-carrier with the cam-ring, so that said lever will be put under the control of the automatic devices l or moving it during reciprocating knitting. Fig. 5 is a vertical section taken across the bed or cone in which the needles reciprocate and some of the surrounding cooperating parts.

Fig. 8 is an enlarged sectional detail of the toe-cam and some of its operating devices. Fig. 9 shows in perspective the toe-cam. Fig. 10 is a detail showing part of the lever which cooperates with the thread-carrier to move it continuously or intermittingly, as may be required. Figs. 1] and 12 are details showing parts of the circularly-moving rings and their cams, to be described. Fig. 13 is a detail in side elevation of some of the devices employed for effecting the change from circular to reciprocating knitting, and vice versa. Fig. 14 shows the trol the working position of the stitch-cam, and consequently the length of the stitch, the

cam being useful in fashioning the goods.

I have also sim liiied the means employed. to both rotate ant reciprocate the cam-ring,l having reduced. the size and number of parts commonly used for that pur ose, and conseuently have reduced the weight of the parts, llhereby cheapening the construction of the machine and lessening the operative space re uired for it.

have also devised a novel means for imparting circular movement to the means instrumental in determining when the points are to be changed in position, said means includin rings having lugs and lyin one above the, ot er and presenting perip eral teeth which are engaged, respectively, each by one of a pair of pinions, one of the pinions of the pair imparting) movement to the other pinion of the pair, 0th pinions consequently eing actuatedby one pair of pawls directly under the control of a suitable pattern-surface, the pawLcarrier beingin this instance of my invention movedcontinuously both dursection of the hollow cylinder or thread-carrier, showing the thread-guiding device and the opening in the bod of the cylinder for the passage of the thread to the outside of the cylinder.

The framework of the machine consists essentially, of legs A, standards A erected thereon, said standards having fixed to their upper ends a bed-plate A, the, shape of which is shown best in Fig. 5, said plate bcingpro vided with a central opening A, through which the knitted work passes, said plate having secured thereto the shank B conical -needlebed A providedwith suitable grooves for the reception of a series of latched end of said conical bedf needles a, theupper having a suitable pivot-or rest for a series of acks or sinkers A moved by a sinker-actua projeoting'ear' e en circular knittingis being done is acted upon continuously by one of two like studs a, carried by a plate a, to be described, said late having two such studs to act alternatei on said ear to move the ring A back and orth for reciprocating knitting. The shank B of said conical bed is surrounded loosely by a cam-carrying rin B, said ring having teeth B to be engaged and moved by the teeth of the bevel-gear B. This ring B has attached to it by suitable screws a (see Fig. 1) the cam-lock a said cam-lock being shown detached in Figs. 6 and 7. Said ring also at a point opposite said camlock has attached to it by screws a the plate a before referred to, the weight of the plate a being such as to form a balance for the weight of the cam-lock a". The ring B, it will beseen, thus becomes a cam-carrying ring, because it carries the cam-lock a, to be described. The bevel-gear B is adapted, as will be described, to berotated at times forrotating the cam-ring during circular knitting and at other times to reciprocate it for reciprocating knitting. The cam-ring B has attached to it by screws a 'flat feet a" of a narrow ring a, the upper edge of which forms a continuation of the under line of a non-knitting groove. The cam-ring so'made is a skeleton ring, and its weight is so greatly reduced that its motion may be reversed without straining the machine to overcome its momentum, and the lighter the weight of the cam-ring the less the expenditure of power to drive it.

The shaft h, carrying the gear B, has fast ating rin A 'havin (see Fig. 3,) which wii all times by a pinion A, fast on 'tached in Fig. .end'a roller'22 ofain a notch 16 of a p on it a pinion B, which is at all times ongaged b the teeth of a gear A loosely mounte on a main or slow-motion shaft A said shaft having fast on it. a toothed gear A positively at the power or which is engaged and rotated driviizlg shaft A provi ed with any'usual devices by which to rotate it at a fast speed for circular knitting- .and at a slower speed for reciprocating knit-' ting,- as common c ine.

The goal A has at one side a lime, (see Figs. 3 and 13,) which is cut away at dia-' metrically oppositepoints, as shown in Fig. 13', for the opposite en y done in this class of inasofa sliding plate h, (shown de- 14,) said plate having at one roller-stud 21', suitable springs 7v acting normally to cause said roller 22 to its periphery outside said rim, suitable guides 23 acting against the side edges of the plate to direct its movement, said s rings also tending to normall keep thero ler-stnd 21 ate A, fast on the slowmo'tionshaftA.

said shaft in practice being and. at its otherend a small stand with The hub b of the disk a has loosely mounted on it a slpider A having a projecting slettodarm "and carrying 'a ivoted dog it, acted upon by a spring h. has at itsfree end a lug which normally stands'in a notch 24 inthe spider, said notch being enlarged at 25 next the end of said lug.

The framework of the machine has a vertical stud I)", (see Figs. 3 and 13,) on which is pivotally mounted a .lever 6 upon one end of whichis pivoted at b a shoe 1)", having a concaved face, said face standing normally during circular knitting at one side of the rib a so that the roll as said gear is rotated does not strike the shoe.

When the plate is under the control of its springs and the shoe is not in the )ath of movement of the roll 22, then the roller-stud 21 stands in the notch 16 of the disk A locks said gear'A to said shaft A", and the gear A is rotated continuously through said disk for circular knitting; but when reciprocating knitting is to be done the said shoe is turned automaticallyinto position so that the roll 22 may strike said shoe, and the sliding plate is moved in a direction to cause the roller-stud 21 to leave the notch of the disk A, fast on said rotating shaft, thus detaching the gear A from the disk and leaving the gear free to be moved by some other source, said roller-stud 21 moving with the gear A, entering the notch 25 at the end of the dog it in the spider A and as said spider is always reciprocating, as will be described, said spider at once, by engaging said stud, be-

comes the moving device for said gear A and this gear will be reciprocated, and the cam-cylinder will also be reciprocated for rehe dog and 80 assagethrough said rim ofzthe I i The slotted arm A of the spider has connected with it a link A, adjustably attached to a slotted arm A, fast on a rook-shaft A, said rock-shaft having an attached second arm A, to which is adjustably attached a link A, (see Fig. 3,) in turn fitted at one end over a stud A, carried by a disk A", also fast on said continuously-rotating slow-motion shaft A.

The shoe b is supported at one end by a suitable spring l).

The lever I) is (see Fig. 3) slotted at one end, and said slot receives a pin (2, extended I from a lever d, pivoted at d on a lug of the standard A. The lever 11 (see Fi 3) has connected to it at one end an elbowlever (1, (shown in section in Fig. 3,) the up or end of said lever (see Fi 2) being acte u on to move itat desired times by a suitab e projection of the pattern-chain C, which is carried by a cylinder C, fast on a shaft e", which has secured thereto at one end a toothed wheel The wheel 0 is actuated intermittently or step'by step to thus turn the cylinder 0 and move the pattern-chain by means of a cam-arm 0 extended laterally from the plate C, secured to the gear A, before described. As the gear A rotates the camarm C engages the teeth of Wheel C and turns it, as will be obvious, and such movement will be intermittent, depending upon the character of arm C and number of revolutions of gear A The opposite end of said lever d isshaped to enter'a hole d? (see Fig.

lower end of a lever d, pivoted at d on a stand (1, depending from the bed-plate A, the upper end of the lever d entering a slot in an ear 11 of a carriage d", fitted to slide in ways of a block d, fast on said bed-plate, said carriage havinga cam-slot d, in which is entered a pin d, extended from a slide-bar d fitted in a guide (1 upper end with two controlling-cams said cams occupyin their uppermost 081- tion (see Figs. 2 and 4) when circular nittin is being done and being moved into their lowermost position when reciprocating knitting is being done. i

The bedlate A has supported thereon a suitable hu e, which receives a posts, made and provided at it dis d),

. adjustable in said hub by a suitable set-screw e, to thereby adapt the machine to the size of cone used. This post has pivoted upon it at e a socketed arm e, in which is entered and held adjustably by a set-screw e an arm a having at its outer end a split collar 6, which may be clamped to ether by a suitable screw 6, said split col ar entering an annular groove at the outside of the thread-carrier,

screw the collar may i) in an ad ustable link d, ointed at d to the and shown as com osed of a hollow cylinder e having at its ower end a flaring shielde, which serves as a thread-rest and a latchuard. The cylinder has located centrally in it a thread-guiding device e, shown as a roller, to not only lessen friction, but also to facilitate the easy introduction of the thread. The body of this cylinder below the split collar is provided with a suitable opening 0 to permit the passage of the thread from the center of the cylinder to the outer side of the latch-guard or shield on its way to the needles, said thread in its passage from the thread-guiding device e to the needles runnin r through some suitable guide, as e, the sair guide in this present instance of my invention being re resented as a funnel or chute, and the delivery end thereoi is shown in Fig. 2 and Fig. 20. Locatinr the threadguiding device a centrally wit relation to the cylinder and leading the thread out from the lower end thereof enables said cylinder to be either rotated continuously or to be reciprocated without liability of the thread catching improperly in any stationary art of the machine, and henoe'this central ocation of the thread-guide becomes an essential feature of this invention. The particular eye or device which directly delivers the knittingthread to the machine from the shield is immaterial, and instead of the eye or chute shown I may em loy any other usual or suitable thread-gui ing device commonly employed in knitting-machines. In this instance of my invention the outer portion of cylinder 6 (see Figs. 1, 2, and 5) has a flange e and above it a collar e attached thereto by a suitable screw 6 and loosening said be adjusted up or down that it may be made to on said cylinder e so iTlGtlOn against the said act with more or less s )lit collar; but ordinarilythe adjustment of t e split collar will be all that will be rec uisite. The cylinder, it will thus be understood, constitutes'the thread-guide-that is, the thread is taken into the hooks from the. projecting end of the guide e, whence it passes to the needles under the adjacent edge of the cylinder e By adjusting the post e up or down in the socket e the shield and latch-opener e may be put in exactly the proper osition with relation to the upper ends of the needles and the size of the cone used.

The socketed arm 6 andthe thread-guide may be turned up when it is desired to employ a transferer to put a top or other device on the hooks of the needles, they being then arranged in a circle; but when knitting is being done the said arm and thread-guide will oocu y the osition shown inFigs. 2 and 5.

he cylinder 6 has attached to it arms a and e? b suitable like screws e" passin through s ots made in the curved shanks o the arms e 6 both shown in Figs. 1 and 2,

. most position.

said arms being preferably made adjustable toward and from the point where the thread is delivered to the needles, to thereby secure accurate movements for the threaduide With relation to the needles used. In t e instance of my invention shown in Figs. 1 and 2 the said arms are located in different horizontal lanes, and when circular knittin is being dbne, the thread-carrier being t ien rotated continuousl the arm 6" is acted upon continuously y the end of a suitable lever e pivoted at e on a stand a, erected on the cam-lock a, a lug 6 at the outer curved end of said lever at such time assing freely between the acting faces .of t e toecams d" and d", they occupying their upper- One side of the lever e is shown as acted upon by a friction device c composed, as herein shown, of a spring-steel arm erected on the stand c, it havin an attached friction-face, which may be of leather, said face being represented by dotted lines behind said lever in Fig. 2, said arm also having two stops e e to limit the extent of movement of said lever. r

The bed-plate has fitted within it two rings f and 9, adapted to slide therein, the latter ring 9 resting on a shoulder g, forming part of the said bed-plate, and the ring f rests on the ring 9, both rings 1 ing within and being guided externally by t e upturned wall 9 of said bed-plate, the upper ring f being artially overlapped by a flanged ring f he ring f has attached to it at its upper side by suitable screws 2 (see Figs. 1 and 12) a steel plate, a portion 3 thereof being bent upwardly above the late and the ring f and the said upwardlyent plate is split, so that its ends may be bent, as at 4 5, to constitute cams. suitable screws 2 (see Figs. 1 and 11) a suitalgle steel plate 3 having cam-shaped ends 4 5 During circular knitting the rin s and remain at rest, and the cams 4 5 an 4 5 are at their farthest distances apart, and the lever e rests against the lower stop a", and the end of said lever lies in contact with the arm 6 as shown in Fig. 2, and the threadcarrier is rotated in unison with the camring. Now when reciprocating knitting is to be commenced the cams (Z and d are automatically depressed by or through the pattern-surface, as described, causing the upper cam d to meet the lug e, which slightly depresses the outer end of the lever 2", thus putting it in such position that said lever inits movement with the cam-ring will meet the end 5 of the plate 3 of ring f, which will turn said lever e far enough to raise its inner end from contact with the arm 6 thus immediately leaving the thread-carrier at rest, so that it will no longer travel in unison with the cam-ring, the latter continuin and completing its usual movement, this isengagement The lower ring 9 has attached to it by I of the lever and arm being made just after each reciprocating course 111 either direction. This ma be done through the two plates 3 and 3 aving the cams described and carried by the two rings f and g, said rings just when or after reciprocating knitting is to be done being started by means to be hereinafter described, and moved intermittingly with respect to each other after the completion of each stroke during narrowing, and when the narrowing has been completed the said rings are moved intermittingly in the opposite direction to thus again separate said springplates ard their cams so that they operate the lever e at a later period in the stroke of the cam-ring until the widening has been completed and circular knitting is to be again commenced, at which time are put into their uppermost position, and on this movement of the said cams the lever e is again put against sto e It has been stated t at the thread-carrier during reciprocating knitting will be moved for a greater or less distance according to the length of the reciprocating course being knitted, such movement bein effected through the lever e but in order t at said lever shall so operate it must contact when the camring goes in one direction with, say, the arm e, and in the opposite direction with the arm c and-the time that the said lever-engages one or the other ofthe said arms must be automatically controlled. This is effected by or through the camlates 3 and 3 Let it be assume that the last course of circular knitting is being made and that the cam-ring B is atthat time moving in the direction of the arrow 10, (see Fig. 1,) and at this time, it will be remembered, the cams d and li are automatically lowered reparatory to reciprocating knltting, so t at cam what the outer end of the said lever e and lifts the inner end thereof somewhat with relation to the arm e with which it is in engagement. Now in the further rotation of the cam-ring in the direction of the arrow 10, Fig. 1, the lower end of said lever strikes the incline 5, which immediately further turns the said lever, lifting its inner end above the path of the arm e so that as the cam-ring continues its motion the said lever e elevated from contact with the arm 6, will leave the thread-carrier at rest. The cam- This threadthread-guide will be stopped at the end of the cams d d Ice IIO

d meets the lug e, which depresses somering continues its motion to the full and of its stroke and is then reversed, and as it comes back the elevated inner end of the lever e" meets the end of the arm e, located in a higher plane than the arm e and immediately picks u and moves the thread-earner in unison with it; but when said thread-carrier has been moved so as to feed the thread to the desired number of needles to be used in that reciprmzating course the outer end of the lever c strikes the cam incline 5 on the outer side, which l fts the outer end of said lever, moving its inner end downwardly away from the arm 0, and the cam-rin continues its movement to the end of its stro e, leaving the thread-carrier at rest. On the return stroke of the cam-ring the depressed inner end of the lever 14'' in line with the arm e meets said arm and picks up and moves the thrmtd-carrier with it until the outer end of the lever c again meets the inner side of the incline 5, when the inner end of said lever-e is again lifted to pass above over and away from the arm c.

The spring- plates 3 and 3 have been described as provided with. inclines or cams 4 and 4 but these inclines or cams do not in the operation ofthe machine perform any work; but they are offset, as shown, in order that the outer end of the lever a, after the same has been moved by one of the inclines 5 or 5"", may on the return movement of the cam-ring and lever act to position the end of the lever correctly with relation to the central part 3 or 3* of the spring-plates should the said lever from any reason either due to centrifugal force or shock be turned somewhat on its pivot e accidentally.

The arms 0 and a are located close to the thread-delivery, one at one and the other at the opposite side thereof, and by adjusting these arms toward or from the line of threaddelivery the thread may be led to the needlcs of any cone correctly to enable any desired needle to be the first one fed for reciprocating knitting.

i believe myself to be the first to provide thecam-lock or cam-ring of a circular-knitting machine with a lever or other moving device substantially such as herein described under the control of suitable cams, lugs, or projections by which said lever device may. m moved into one and then into another position to engage and disengage at desired times an arm or projection extended from or connected with a thread-carrier, so that said thread-carrier may be, as it were, detached from and left by the moving cam-ring at any desired point in its stroke, and therefore this invention is not limited to the exact lever or device (1 herein shown; but said lever or device may be variously modified-as, for instance, see Fig. 15, where is shown a lever h, pivoted at h on a stand h which may be erected on the cam-lock-and this lever may cooperate with one arm-for instance, arm eextended from the threadcarrier, it meeting first one and then the other side of said arm, said arm e in such modification being located immediately above said thread-delivery. The lever has,

at one end a slot, as h, in which may be placed a roller or other stud it, connected with a link or foot h pivoted at It on a block h", free to slide up and down in a slot h of an arm h of said stand it". The lower end h of the link or foot is normally ke t depressed below the lower end of the arm by a suitable spring it, connected in this instance with a stud h, fixed to the stand and to a screw or stud fixed to the lever h. The

upper end of the link 71. has a projection h provided with a hole which embraces the end of a rod it, connected with the lever h and surrounded by a suitable spiral spring h, the said spring acting normally to kee the said link in upright position. This lin may be acted upon at suitable times by the inclined ends it of cam-lugs h", which may be fixed to two rings having circular moyement. as described, of the rings f and g, and said rings may be either constructed as shown in this application or said cam-lugs may be applied to a ring which has imparted to it not only a circular motion, but a rising-and-i'alling motion, as in United States Patent No. 542,055, dated July 2, 1895. The upward movement of the leg h" by one of the said cam ends depresses the inner ends of thelever h to remove it from contact with one side of the single arm extended from the threadcarrier with which it cooperates, and as soon as the leg passes off of the end of the said cam the spring h immediatelyacts to elevate the inner end of the lever it, again putting it in the path of the arm extended from the thread-carrier, and the cam-ring continues its movement to the end of its stroke. On the return stroke the end of the lever it must meet the opposite side of the armextended from the thread-carrier in order to move the thread-carrier in the opposite direction, and in order that the end of the lever may remain in its elevated position and not be depressed by the cam referred to the inner edge h of the leg it meets an inclined portion h of said cam, which turns the leg on the pivot h, so that the saidleg is not lifted, as it was when it passed the cam in its stroke in the other direction, and consequently the rollerstud it moves in the slot h and the inner end of the lever is not at all disturbed, but remains in contact with the arm extended from the thread-carrier and moves the threadcarrier until the lower end of the leg h meets a second like cam end h on the other ring,by

- which it is elevated, as just described, so that the inner end of the lever h is depressed below and passes beyond the arm extended from the thread-guide, thus again leaving the thread guide at rest, and this eration will be repeated at each stroke of t e cam-ring during reciprocating knitting.

The cam-lock 01 (shown best in Figs. 6 and 7 and in the section Fig. 8) has two stitchregulating cams m m, two being used because the machine is to knit on the reciprocating stroke. Thesecams are carried by suitable slide-blocks m. The carriage m, carrying the cam m, has a stud m which is extended outwardly through a slot m In the cam-lock a, said lock having ad'ustabl secured to it a late m whichis seti or the ongest stitch to e made in heel and toe work, and the cam m is adjusted to normally stand in the same position by or through the lowest projection of the pattern-surface; but when a longer stitch is to be made in circular work,

' as toward the upper end of the leg, said cam m is depressed by or through a projection on the pattern-surface acting upon a ring m, (shown in section in Fig. 5 and in elevation in Fig. 1,) said ring having suitable ins or studs m extended from it through t e bed-plate A underneath the rings f and g, the ends of said pins or projections entering suitable slots m (see Fig. 2) in a series of adjustable lates m fixed on the bed-plate A. To li t this ring and render it available to lengthen the stitch, as described, it must be turned, and to a do this I have provided the ring with an arm right-an led stud n, w

m", (see Figs. 1 and 2,) which is extended through a suitable hole in the outer u right wall of the bed-plate, where it is acts upon by a hook m carried by a stud m on an elbow-lever m havin one of its arms extended over and so as to is acted upon b a projection of the attern-chain, the sai projection turning t e said lever m so that the hook m, acting on the rod m, draws the said rod in a circular path, causing the projections m to slide upwardly in the inclined slots m, thus raising the ring. The upper side of the ring as it is raised contacts with a foot m" of a slide or lever m, suitably pivoted at the outer end of the cam-lock a", said lever having jointed to it a link a, which engages one end of a lever m pivoted atm, the opposite end of said lever having an adjusting-screw m", which acts upon the stud m extended outwardly from the slide m carrying the said cam m. The cam-lock also has two like fly-cams n each of which has a wardly t ough a hole in the cam-lock where said stud is surrounded by a suitable sprin n, one end of said s ring being connects with the cam-lock an the other with a suitable pin or projection n, extended throu h or connected with said stud, so that said spring normally acts to keep the fly-cam pressed against the blocks 62 and 63.

The plate of the cam-lock has attached to its inner side, as herein shown, by suitable screws a series of blocks 60, 61, 62, and 63, the

blocks 60 being in duplicate,

ch is extended out,

and they are so shaped at their under sides and so located wit relation to the blocks 61, 62, and 63 as to leavebetween them what I designate as the knitting-groove n, the said knittinggroove intersecting the lower edge of the cams m and m before described. The outermost ends of the blocks 60-have ivoted on them the fly-cams n described, and to the inner ends of said blocks are pivoted the points or switches n n. The central part of the block 61 is provided with a recess to receive a block 64, it being attached to the block'61 b3 a screw 65. Above the concaved upper e geof the block64 ispivotedadirecting-cam 66, said cam occupying a position between said points or switches n n, the directingcam dependincg in a space between the lower a gui e edges 0 -plate 67.

he top edges of the blocks 60, 62, and 63 and the fly-cams n and the top of the block 64 and the up or edge of the ring a, constitute one side oi what is designated as the nonknitting groove u the only opposed side be ing the small ui'de-plate 67 and the directing-cam. In t e patents referred to the nonknitting groove had a continuous top wall extended entirely about the cam ring; but for cheapness of construction and to lessen thedwear on the butts of the needles when in sai the butts of the needles in said groove free to be seen I have done away'with most of the upper wall of said non-knittin groove.

he fly-cams normally stan in position to close the knitting-groove and prevent the entrance ofneedles therein at that point but they are free to rise and permit the passage of the butts of the needles from the knitting-groove into the non-knittin groove n.

Substantially mi wa cams m and m I have ocated the needle-selecting devices, composed, essentially, of the two points or switches n n, represented as pointing one toward the other, and a directing-cam 66, loosely pivoted and lyil'ig between the s'aid points or switches, said directing-cam being free to be struck by the butts of the needles when the cam-ring is moving in either direction, so that it if the free ends of the said points or switches are elevated will insure the passage of the butts of the needles under the points or switches into the knitting-groove 11,; but if the free ends of said points or switches are depressed then the butts'oi the needles on arriving under the between the stitchdirecting-cam pass beyond it over the tops of the free ends of the points-or switches and remain in the non-knitting groove and do not knit. In Fi 17 I have shown oneof these points or switches detached, and it will be seen that it has extended from its back a stud n. The studs extended from these points or switches enter each a hole in a sliding plate n", entering a suitable groove in the 95 non-knitting groove and to also leave passes throu h a cam-slot a, made in an arm n, extende from what I herein designate as a toe-cam N, said toe-cam having two toes n" 71., extended from a hub n in opposite directions and in different planes. The hub of the toe-cam has a hole a", which is passed over a stud a, rising from the cam-lock.

The arm n of the toe-cam rests at its under side upon a rock-shaft n", a portion of which is slabbed off or cut away at 11. (see Fig. 8) to leave a secant surface. This rock-shaft has connected to or forming part of it a ear a, which is engagedby a segmental rack n at one end of a lever n pivoted at n on a stand a, erected on the cam-lock, the outer or left-hand end of said lever, viewing Figs. 2 and 8, being so located as to pass between the two cams d d when the said cams are in their u permost position and circular knitting is eing done; but when reciprocating knitting is to be done and the said earns (1 cl are depressed, as stated, the up ermost cam d meets the upper side of the ever a and depresses that end, turning the rockshaft until the secant surface a comes immediately under the arm a, thus letting the toecam drop and put'the toes n" n in position to strike a ainst the devices, which at each stroke of t e cam-ring in reciprocatin knitting act to turn the said toe-cam to t ereby cause its slotted portion a to act at the proper time through the stud n to thereby move the piate n to either elevate the saidpoints or switches to pull down the needles from the non-knitting groove into the knittingroove for knitting either in continuous I circu ar courses or for reciprocating courses, as in narrowing and widening, or to depress said points or switches to retain the butts ofsaid needles in the non-knitting groove. 1 have previously described in the preamble of this s ecification the action of these points or switc es in their elevated and depressed potions, and their action is as common in the patents previously referred to so need not be erein furtherdescribed; but I will now describe how the toes of the toe-cam are acted upon and moved at the proper times.

, Referrin now to Figs. 1, 5, 11, and 12, the

- rings f an g before referred to are therein has secured to it represented, and the ring b suite le rackb suitable screws 0 an p ates 0 each having suitable depending lugs,

as 0 0, the contiguous ends of said lugs being oppositely beveled, as best represented in Fig. 12, and it will also be noticed in Fig. 1 that the said lugs stand in different circles, and in 1 Fig. 12 they stand at different levels viewed from a horizontal glane. Supposing, a ain, that the cam-ring is moving in the weetion of the arrow 10, Fig. 1, in its last course of circular knitting preparatory to being reversed for reciprocating knitting and that the cams d d have been depressed to put the toe-cam down, as described, with its toes n n in working position. During the last partof the last circular course the under side of the toe it meets the bevelede'nd of the lip 0 and the toe-cam is turned to depress 'the points or switches a a between the two needles, as described, so that thereafter no'more needles will enter the knitting-groove a, but

will follow over the tops of the point or switch just turned under it into the nonknitting groove, and by the time that the last needlepasses thefl -cam n and enters the non-knitting groove t 1e first needle to pass over the point will be found in position alongside 'the'last needle and the butts of all the needles will be in the non-knitting groove. Now the machine is in condition to be reversed, and as soon as the points or switches in the first reciprocating stroke of the machine opposite the arrow arrives in a position to have a point or switch elevated between two needles to thus }grab and pull down i into the knitting-groove t e first of the series of needles to be used for a narrowing or widening course the shoulder of the toe it" meets the inclined end of the lug 0 whichimmediately turns the toe-cam in the direction of the arrow near the toe a" in Fig. 9 and again lifts the points or switches into position to engage and depress the first needle to be used in that reciprocating course, and the points or switches remain up until all of the needles to be used in that reciprocating course have been taken from the non-knitting groove and put into the knitting-groove to knit, and when the last needle of said course has completed its operation the toe n of the toe-cam meets the beveled end of a lug 0 fast on the ring g, said lug again turning the toe-cam, causing the points to be depressed between two needles, and thereafter the butts of the needles in the non-knitting groove pass over the points or switches, while the butts of the needles then in the knittingroove pass out of said knitting-groove into t e non-knitting groove in front of the needles traveling in the non-knitting grooves until the butts of all the needles are again in mass in the non-knitting groove. The cam-ring completes its recipro cating course and comes back, and as soon as it arrives op ositc the needle to be a ain depressed for tile first needle of that reciprocating course a like cam projection of the toe n" meets the beveled end of a lip 0 extended upwardly from the ring g, which again turns the toe-cam to elevate the points or switches so that the needle to be the firstv of that course is immediately drawn down into the-knittinggroove.

The lugs 0 and 0 are directed, res ecmotion to thereby The plates 0 carrying the lugs 0 ojiand the plates carrying the lugso 0 may be adjustfirst needle of a reciprocating course and also to enable a point or switch to pass between the butts of any two needles, one of said needles being the last one to be used in the reciprocating course. It will be understood that the lugs 0 0 on one side of the machine I 5 J and the lugs 0 0 on the other side of the machine stand at their farthest distances apart when reciprocating knitting is commenced and that at the end of each stroke of reciproeating knitting the said pair of cams are :0 moved intermittingly one toward the other until the narrowest course of reciprocating 'knitting is being made, and then they will be gradually moved intermittingly in the opposite direction back for widening into their 2 5 starting position. I will state, however, that these rings are not in this particular machine moved at the first two strokes of reciprocating knitting, I not moving them, because I have found'that by laying in two courses of reciprocating knitting before commencing to narrow it is possible to make a better junction of the narrowed part with the circular part thanwould be the case if the rings carry- 1ng the lugs were moved with the first nar- 5 rowing course. I will now describe how these rings f and g are moved intermittingly in opposite directions. I have devised a very simple means for this purpose, my means containing but very few parts of light weight,

0' low cost, and easily actuated. Each of these rings is provided with teeth at its peripher the said teeth extending substantially halfway around each ring, and the toothed parts of these rings extend through a slot in the up- 5 per vertical wall 9 of the bed-plate, as seen The upier ring.

at the right in Figs. 1 and 5. f is engaged by a pinion 34, connecte with a sleeve 36, having at its lower end a pinion 37, said two pinions and sleeve being loose on a shaft 35, held in a suitable'bearing 38, connected with the bed-plate. The bed-plate has another. suitable bearing 39, in which is mounted a shaft. 40, (see Fig. 1,) provided at its upper end with a toothed pinion 41, the

pinion being of sufficient thickness from top to bottom to not only engage the teeth of the ring g, but alsoto engage the teeth of the pinion 37 referred to, so that in the rotation of the pinion 41 it acts to move the ring gin one 6o direction and, acting through the pinions 37 and 34, causes the pinion 34 to move the rin f in the opposite direction, each being move at exactly the same time in op osite directions without any ossibility o slip or lost d isarrange the relative positions of the cam-lips and devices carried by said rings. The lower end of the shaft 40 has attached to it a pinion for ratchet-wheel a,

(see Figs. 2 and 3,) and/said ratchet-wheel is pawl-carrier once during each rotation of said shaft. Each pawl c and c has a like tee a, which butts against a projection of the ear 0 and is kept there in a yielding manner by a suitable spring 0, the toe c limiting'the inward movement of the pawls c and c.

To provide for the pawls c and 0 contacting with the ratchet-wheel c" to move the shaft 40, I have provided a lever 44, pivoted at 45. One end of said lever has jointed to it a link 46, connected to the lower end of an elbow-lever 47, pivoted on a stud held in a boss 48 (see Fig. 2) of the framework, the short horizontal. arm of said elbow-lever being slotted, (see Fig. 19, where said lever is shown in detail,) the said slot receiving a pin 49, extended laterally from the elbow-lever d, before described, so that when said lever is elevated or moved by the pattern-surface the lever 47 is consequently moved. The front end of the lever 44 referred to has con-v nected'to it a link 50, which embraces loosely a stud 51, carried by a plate 52, pivoted on a stud 53, erected on a plate 54, fast to or forming part of the standardA (See Fig. 2.)

The pawl-carrier C, before described, in its forward'and back reciprocation is guided by the plate 52, before described, and the forked end of the carrier slides back and forth on or about the stud 51, and when it is desired to place one or the other of the pawls c or c in engagement with the ratchet-wheel c the lever 44 must be moved.

Now assuming that it is desired to place the pawl c in engagement with the ratchetwheel 0 then in such case the pattern-surface will automatically at the proper times move the inner or short arm of the lever 44 to the left, viewing Fig. 3, and will carry the plate 52 and the pawl-carrier laterally, thus putting. the pawl c in engagement with the teeth ofthe ratchet-wheel, and said pawl will remain in engagement with said teeth and in the reciprocations of the pawl-carrier will move said teeth and the shaft 40 as long as the rings are to be moved in the direction for narrowing, and, the narrowing completed, the lever 44 will be again moved in a direction to insure the placing of the 1pawl c in position to engage the ratchet-w eel c and turn IIO lo 824,,d08
