COMPANY, OF PAWTUCKET,'RHODE ISLAND, A CORPORATION 0F MASSACHUSETTS AUTOMATIC CIRCULAR-KNITTING MACHINE Application filed .Tune 9,

The invention has relation to automatic circular knitting machines; in the more specific phase thereof, it relates to machines of such class employing individually reciprocating cam-actuated independent needles.

The invention provides a double-feed machine adapted for the production of stockings having high splices and double soles, i. e., spliced soles. The general aim of the invention is to increase the productiveness of an .automatic circular knitting machine adapted to knit stockings having ,the features just mentioned, wit-hout increasing the speed o f the machine.

The main principles of the invention, and certain of the specific features of invention, are applicable in the case of latch needle machines, as well as in the case of spring-bearded needles. Certain of the principles and features thereof are'applicable more particu-l larly in` the case of machines employing spring-bearded needles.

The accompanying drawings show as an illustrative embodiment of the invention in' its general entirety a spring-bearded needle machine. The manner'and means of applying in the case of latch needle machines the principles and features of invention which are applicable to machines of such type will he apparent to those skilled in the art in the light of the disclosure in the said drawings and in the following description.

Usually in practice, in the process of knitting a stocking having a high splice and a foot with double orispliced sole upon an automatic circular knitting machine on the order of the well-known Banner machine, having a' single feed-station, the garter top and adjoining portion of the upper part of the leg 40 are knit of a yarn supplied by one of the yarn-guides, and the remainder of the leg to the beginning of the heel is knitwith a yarn supplied by another yarn-guide. For the high splice a splicing yarn, supplied by its yarn-guide, is added to the yarn last mentioned in knitting those portions of the respecs tive ankle courses which are at the back of the ankle. The heel is knit of one or more yarns l'supplied by the yarn-guide or guides 1922. Serial N0.' 567,052.

knit of a yarn supplied by the proper one of the yarn-guides, for instance the main leg yarn, with the splicing yarn introduced into those portions of the respective courses which comprise the sole. The toe is knit ofthe same yarn or arns as the heel. In this process, during t e production of the leg, and of the foot between the heel and toe portions, ai single round or course of stitches is knit in each revolution of the machine'.` Hence considerable time is consumed in the knitting of the leg and foot. f

Double-feed machines, broadly considered, have been known in the art, but,so far as'I am aware, double-feed machines have never been organized and adapted to the knitting of stockings having, high spliced ankle portions and spliced or double soles. The nearest thereto has been the adaptation of double-feed machines to knit split-foot stockings; i. e., stockings in the case of which the body of the foot of a stocking is composed of two longitudinal halves united to each other by sutures along thesides of the foot. Such machines have not been adapted to produce stockings having high spliced ankle portions and foot portions composed of continuous round and round courses of the same yarn or yarns and.

having splicedl or double soles.A As organized heretofore they have not been capable of placing a splicing yarn in and out of knitting relations at the proper points in every course in knitting a high splice and a double or spliced sole.v The endeavor to knit such goods upon a machine having a double-feed and equipped with devices for supplying a splicing yarn at the main feedonly would result in the production of a high splice or double sole in. which alternate coursesonly of the ankle or foot would contain partial courses of the splicing, yarn.

The importance of increasing the productiveness of automatic circular knitting maa chines without increasing the speed of the ma,- chine is obvious. There .are limits to the speeds at which such machines can be run successfully. This is true of machines employing latch needles as well as still more forcibly true of machines employing springbearded needles. In particular,` a springbearded'machine is of limited speed capacity, this being true especially of spring-bearded needle machines of that type in which the needles are moved by cam-action individually and independently of one another for stitch-- forming purposes, and are drawn to form the stitches. There is in the case thereof a speed which cannot be exceeded without breakage of needle-beards as a result of crystallization.

The general aim of the invention is attained by the present invention in a doublefeed machine, namely, a machine having a secondary feed-station, vincluding stitch-cams, so that two courses of stitches may be formed in each revolution of the machine, through providing such machine with yarn-splicing devices, and in addition with means for controlling the knitting at said secondary stationsso that knitting may proceed thereatduring the production of a stocking leg and be suspended during the production of the high spliced portion of the stocking, and of the heel, foot and toe.

In the case of a machine embodying the main principles of the invention two courses are knit in each revolution of the machinev throughout the production of the leg of the stocking, down to the beginning of the high splice. `At such point, knitting at the secondary feed is suspended during the knitting of the ankle portion with a reenforcing thread in the high splice at the back of the ankle portion, as well as during the product-ion of the heel, the production of the foot with its double sole, and the production of the toe.

In carrying the invention into effect in a spring-bearded needle knitting machine I provide special features in connection with the presser-cam at the secondary feed-station, and with the stitch-cams at such feedstation. The ring carrying the presser-cam has combined with it means whereby, at the point of beginning to knit the high splice, it is actuated to place the presser-cam of the secondary feed-station in an inoperative positiOn.

The machine that is shown in the accompanying drawings is the well-known 'Banner machine, adapted to the employment of spring-bearded needles, and designed with modifications and additions for the purposes of the invention, as will be apparent from the following description. The fea- `of the parts which are involved more immediately in the invention.

Certain of the parts that are shown in the drawings hereof correspond with those of Patent No. 933,443, and are designated herein by the same reference characters as in the said patent. Thus, in Figs. 1 and 2 the machine-frame is marked a, the rotatable needle-cylinder is marked N, the needles occupying the grooves or tricks thereof are marked n2, the non-rotatable cam-carrier is marked H, and knitting or stitch-cams corresponding with certain of those of the said patent are marked m, e2. The pulleys (shown in Figs. 1 and 3) for the driving-band of the machine are marked p, p', p2, (respectively quick-speed, slow-speed, and loose or idle,) and at s (Fig. l) is the main shaft, on which the said pulleys are mounted.v At s (Figs. 1 and 2) is the pattern-shaft, f and g being the main pattern-drums or pattern-barrels upon the said pattern-shaft, and f being the series of cams on drum or barrel f which acts upon member b4 carried by clutch-shifting lever b to control the said lever and through the same control the working of the machine to produce either continuous rotation of the needle-cylinder or reciprocating action thereof, as required. The details of the mechanism cont-rolled by pattern-cams f, throughvers or fingers f3 which Irespectively are connected with the respect-ive yarn-guides through intermediate devices of well-known character. At F are the pattern-controlled instep cams which, through engagement at the proper times with the long butts, n, of the instep needles, raise out of action the needles which are not utilized in knitting the heel'and toe of a stocking; and on the com.- pletion of the heel or toe depress the said needles so as to restore their butts to workv ing relations with the stitch-cams of the main and secondary feed-stations. At R, R, are the narrowing pickers by which needles are successively rendered inoperative for narrowing purposes in knitting the ,first half of -a heel or toe pouch, and at T, T, are the widening pickers by which the same needles are successively rendered operative again for widening purposes in knitting the other half of ak heel or toe pouch.

-, At fm, Figs. 1 and 3, is the pattern-lever or linger through which certain of the pattern` indicators of pattern-drum or barrel f act to cause the yarn-guide 5, Fig. 3, for the splicing yarn to be either raised into inoperative position, to discontinue the feeding of the said yarn to the needles, or lowered to provide for delivering such yarns to the needles so as to be knit. In order that during the knitting of the spliced portions of the stocking the splicing Vyarn-guide 5 may be raised and lowered alternately in every revolution of the machine, so that the splicing yarn shall be interknit with the main yarn only partway around in each course, I employ in practice convenient means for the purpose, as for instance means such as shown and described in U. S. Letters Patent for knitting machine, No. 1,293,743, granted under date of Feb. 11, 1919, upon my application. At 62, Fig. 1, is the rotating cam of such means, from which the raising and lowering movements of the splicing yarn-guide 5 are derived.

Referring now to the secondary feed-station which I employ in reducing the invention to practice,-

Two yarn-guides, 7 and 71, are shown employed at the secondaryfeed-station.l One of them ordinarily will control a yarn for use in knitting the garter top of a stocking, corresponding with that yarn which is provided at the main feed-station for use in knitting such portion of a stocking. The other will controi a yarn similar to that yarn which is supplied at the main feed-station for use in knittingthe remainder of the leg of a stocking. Hence it is rendered ossible to knit concurrently two courses of 1i e yarn at each revolution of the machine in producing the garter top, and likewise in producing the remainder of the leg downto the beginning of the high splice. These two yarn-guides are combined operatively, through intermediate `devices of usual. character, comprising

levers

72, 72, engagingl with said yarn-guides, and connecting-rods 7 3, 7 3, with pattern-levers or

fingers

74, 74, which are controlled by annular lines lof pattern-cams or indicators 7 5, 75, in connection with a pattern-drum 76 upon the pattern shaft s adjacent the patternshown in Figs. 8, 9 and 10, as well as other cooperatin cams, are provided at 8 at the secondary feed-station, to' actuate the needles for knitting. In the case of a spring-bearded needle machine, a presser-cam 9, Figs. 3 and 4, is provided for actuating the pressers 10, l

Fig. 4, shown as black rectangles in Fig. 4, to close the spring-beards of the needles against the needle-stems, as required in order to enable the loops remaining on the needle-stems to be landed on the points of the said beards, preliminary, to casting such loops over the tops of the needles in forming a course of stitches.` The presser arrangement may be on the order of that shown and described in U. S. Letters Patent for knitting machine, No. 1,209,256, granted Dec. 19, 1916, upon application of George P. Bosworth. t a

The presser-cam 9 just referred to, at the secondary feed-station, and the two pressercams 11, 111, at the main feed-station, are mounted upon the ring 12, the latter being provided as heretofore in practice with cams (not visible in Fig. 4) for actuating the -webholders, which alternate with the pressers. As will be understood, the web-holder cams are suitable to produce the requisite wave movement of the web-holders in and out radially at each feed-station. The customary rotary shifting movement'of the ring 12 to accord with the shifting of the point at which the stitches are formed inv heel and toe work is provided for as usual, the limits of such rotary shifting movement being deiined through the engagement of a projection 121, extending radially from the ring, with adjustable stop-

screws

122, 122, carried by the small plates 123, 123, which are employed for holding down the ring 12. Plates 123, 123, are fastened upon the top of the web-holder ring or cap 124, which latter is held from rotating, and is adjusted angularly around the axis of the needle-cylinder, through engagement of the ends of adjustable stop-screws 125, 125, carried thereby with opposite sides of the fixed standard 13 by which the yarn clamping and cutting devices are supported.

While knitting is progressing at the secondary feed-station, one of the secondary yarn-guides is down in position to deliver yarn to the needles so as to be knit, the secondary stitch-cams arein working condition, and' the presser-cam 9 is in working position in relation to the stitch-landing point. When knitting is tolbe suspended at such stat-ion, the presser-cams have given to them by the devices which are described later herein angular movement which carries the pressercam 9 of the secondary feed-station into a position such that the needle-beards are not pressed at the stitch-landing point at such feed-station. Consequently, as the needledruml gl Knitting or stitch-cams, including stems descend within the old loops thereon the draw-cam or so-calledvknitting cam 81 such loops pass-under the beards instead of being landed on the points of the beards, and knitting at the said feed-station thereby is discontinued. The presser-cam 11-at the main feed-station which is in action during continuous knitting is of sufficient length to per-' operative yarn-guide at the secondary feedstation is raised through the action of the pattern-mechanism so that the knitting yarn supplied thereby passes inward through the depression of the needle-wave to the inner portion of the circle of needles, and is drawn into the grasp of the auxiliary binder to which reference will next be made, and between the blades of the auxiliary cutter. To prevent running-off of the stitches at the secondary feed-station when the auxiliary presser-cam 9 is rendered inoperative, the shift pf the presser-cam ring is caused to take place in such time-relation to the raising of the yarnguide at such station that the said pressercam 9 ceases to a'ct justprior to the last taking of the yarn supplied by such yarn-guide by a needle. The knitting cam 81 of the secondary feed-station is withdrawn radially outward into an inoperative position, by the. devices which are provided for such purpose, described hereinafter.

The auxiliary knitting cam 81 is withdrawn radially outward from its working position shown in Fig. 8 to its fully inoperative position shown in Fig. 10 by a two-step movement. This action is c aused to take place about four courses after the shift of the presser-camvand yarn-guide or finger. The first step-movement takes place during passage of the long butts a5 of the instep needles by the secondary feed-station, and is sufficient in extent, as will appear from Fig. 9, to enable the knitting cam to clear the short butts n* of the heel and toe needles during the passage of said butts. The second step movement is suflicient, as indicated in Fig. 10, to enable the knitting cam 81 to cle@ the long butts when they come around again, thereby avoiding breakage through contact of such butts with the knitting cam. As the cylinder continues to rotate the needles are leveled up in usual manner by oneof the needle. elevating cams employed in conjunction with the knitting cam 81.

The angular displacing movement of the presser-cam 9 of the secondary feed-station is a backward movement thereof. It is produced in this instance by pattern-connections comprising a bell-crank1251, Fig. 3, working horizontally and having one arm thereof, 126,

engaged with the head of a screw 127, Figs. 3

and 4c, applied to ring 12, a link 128, Fig.- 3, connected to the other arm of said bell-crank,

a rocker 129 to which said link is also connectnon-knitting posit-ion within the needle-circle,

the action of the butts of the revolving series of web-holders within the grooves of the webholder' cams operates to return the ring 12, presser-cams 9 and 11, 11, and the web-holder cams, to their original positions, angularly of the machine, by. a reverse movement of the ring and cams.

The two-step movement of the knitting cam 81 at the secondary feed-station from its working position shown in Fig. 8 first into its intermediate position shown in Fig. 9, and then into its fully retracted position shown in Fig. 10, is provided for in this instance by means of a slide 82 having a slot 83 crossing the slide obliquely and occupied by the head of a screw 84 applied to a projection 85 extending outward' from the' said knitting cam. The said slide is connected by a link 86 to a pin 87 carried by an upstanding arm of a bellcrank 88, Fig. 2, having a horizontal arm thereof connected by a rod 89 to a patternlever or linger 891 controlled by a line 892 of pattern-projections or cams on the third pattern-barrel or drum 76.

Contracting spiral springs 50, 50 connect- `ed with the two pattern-levers or fingers, 74,

74, operating to hold the engaging ends of such levers or fingers in engagement with the surface of the third pattern-barrel or drum, operate to move pattern-

fingers

74, 74, and their connections reversely after having been moved by pattern-projections or cams of the said barrel or drum. Springs 51, 51, connected with bell-cranks 1251 and 88, operateto move the bell-cranks in opposition to the pattern-projections or cams of the said third pattern-barrel or drum. The reverse movement of the parts in connection with the slide operates the slide to move the knitting cam inward back into its normal working position.

In conjunction with the binder and cutter for the yarnswhich are controlled by the yarn-guides of the main feed-station I provide an auxiliary binder and cutter forthe yarns which are controlled by the yarnguides of the secondary feed-station. The two sets of binders and cutters preferably are combined and organized to be mounted upon one support and to be actuated by one train of operating connections. The construction, etc.,-may be varied more or less in practice.

The devices last referred tov are -mounted upon^a supporting arm 14 which is attached to the upper lend of the standard 13. The fixed lower members or jaws of the two sets of binders andcutters are constituted by dif- Latem ferent portions, 151, 152, of a plate carried by the lower end of a block 16, Fig. 6, which is attached to the inner end of the supporting arm 14. Or'the said lower jaws may be made as separately formed pieces that are attached to the said plate 15. The movable jaw or member 17 Fig. 5, of the main binder isy attached to a block 171 mounted between guides 172 on the fixed block 16 so as to becapable of movement vertically, and it is acted upon 1 by an expanding spiral spring 173 that tends 20 is pivoted at 201 upon the fixed supporting arm 14, and in turn actuated by means of pattern-cams upon the third pattern-barrel or drum 76 through intermediate connecting devices. The said intermediate connecting devices comprise the vertically movable rod 21 working through a fixed guide 211 projecting from standard 13. The upper end of the i rod 21 is engaged with the outer armv of the said lever 20, the rod being connected at its lower end with the lever 22, whichY in turn is connected by a rod 23 with a pattern-lever or finger 24 controlled by"means 4of the pattern projections or cams 252 on the patterndrum or barrel 76. The cutter devices cooperating With the main bindercomprise a xed edge or blade 26 upon the portion 151 of plate 15, and a movable blade 27 which is pivoted to the said plate at 271. The said movable blade 27 is actuated through engagement with the binder-actuating lever 18, the said movable blade having a laterally offset portion which works in a slot 182 made in the said lever. When leverV 18 is actuated to raise the movable binder-member 17, it acts also through engagement with the movable f cutter-member to separate the latter from the stationary cutter-member. Thereby the cutter and binder are opened simultaneously to receive a yarn. When the lever 18 is moved reversely, it operates the Nmovable cuttermember 27 to close the cutter to sever the yarn, while simultaneously therewith the movable binder-member 17 is closed down upon the yarnthrough the ac ti n of the spring 173. At 272 is a leaf-sprlnz which 1s pivoted/upon the pivotal screw 2 1 of the vmovable cutter-member 27 and is engaged by a pin 273 projecting from the said cutter- .member into a slot 274 in the spring, so that -the spring accompanies the movable cuttermember in the swinging movements of the latter, while acting to keep the movable cutter-member pressed sidewise against the stationary cutter-member, to insure a good cutting action. The movable jaw or holding member 28 of the auxiliary binder is pressed down upon the upper surface of the stationary projection 152 in connection with plate 15, by means of a leaf-spring 29, Fig. 7, bearing upon the top of the said movable jaw or member 28. The cutter provided in connection with the auxiliary binder comprises a movable blade 30 forming a part of a lever 301 that is pivoted at 302 upon block 16. The said movable blade is arranged to coact in cutting with one edge of the projection 152, and is pressed laterally against the side of movable binder 28 and said projection 152, to

insure good cutting action, by means, of a leaf-spring 303, combined substantially as in the case of the leaf-spring 272 in connection with the movable cutter-member 27. For the actuation of the movable jaw or member 28 of the auxiliary binder to raise the same from the stationary member 152, it is in pin- `and-slot engagement with the bell-crank 31 which is mounted pivotally at 32 on a portion of the block 16, or it might be upon the inner end of thearm 14, the said bell-crank. 31 being engaged'with the lever 20 by means of a projection 311 from one arm of the bell-crank occupying a hole 202 in the lever 20. When the lever 301 is rocked toraise the cuttermember 30, the movable jaw or binder-member 28 is raised `through the engagement of the top edge of the cutter-blade 30 with the pin 281 projecting from the jaw or member 28. v

Through the described combinations and connections the movable jaws or members and the movable blades of the cutters of both at 282, Fig. 5, at its underside, and inthe slit is contained a wire spring 283, preferably made of piano wire, arranged to press against the top surface of the bottom jaw 152, and

.serving to maintain continuously a hold upon a yarn-end occupying the auxiliary binder after the upper jaw 28 has been raised so as to open the auxiliary binder. This holding action is important, it serving to retain the said yarn-end at those times when the binder and cutter devices are operated in connection with change of yarn at the main feed-station at times when no change is required to take placfe at the secondary feed-station.
