This invention relates to splicing or rein-- forcin stockings and other hosiery, especially osiery of the kind having Contiguous I ribbed and plain portions, for example hav ing a ribbed fabric inste and a plain fabric sole, heel, and section a ove-the heel. The invention is particularly applicable to manufacture by circular or seamless tubular knitting, in which it is necessary or-desirable to reinforce by splicing a section of the tubular product having lengthwise extend--- ing boundaries.

Invention in knit-ting; machines has supplied machines' for automaticall knitting ribbed hosiery having plain fa ric soles, heels and toes, for example the machine shown, described and claimed in the appli-- cation of Robert W. Scott, Serial No. 559,506,

filed May 9, 1922, Patent #1,641,554 i dated September 6, 1927, and machines of this type are in great and growing use. Stock 1 ings. of the kind indicated are not necessarily spliced when made of woolen yarn, or'

thick heavy cotton yarns, but when the decorative and useful ribbed instep stockings are made of light'thin yarns, and especially when made of silk, it is desirable to provide a reinforcedfabric at the .sole, and at the back of the ankle above the heel. The narrowed and widened heels and toes may be spliced as usual, by feeding double or multiple yarns during reciprocatory motions of the machine for knitting these parts.

A successful device for splicing must be such as to cause a'supplemental or splicing 'yarn to enter the books of the needles employed in knitting the section to be spliced along with the main or body yarn at each course knit with reliable accuracy in respect to entering the splicing yarn at the same needle and causing itto leave the fabric at the same needle during the making of so many courses as are necessary to provide a suficient length of the spliced area. The competent performance of the entering and leaving operation is best secured by that type of yarn feeding yarn guide which can be relied upon to enter its yarn by rapid downward and outward motion and to withdraw its yarn by upward and inward motion in re-r splicing yarns at the same time.

1925. Serial No. 82,048.

selves or the yarn loops necessarily enga ed in them for the purpose of knitting rib ed fabric close the annular space between the margin of the dial and the interior surface of the space defined by the cylinder needles, and in this case it is diflicult to provide for permitting the float of withdrawn splicing yarn to extend across the circle of active cylinder needles in the position of a chord or diameter, and the needles dial is in'the way of 'a float extending above the dial.

I have therefore devised a spliced article of hosiery having laterally contiguous ribbed and plain portions, the plain portion or a part of the plain portion or any desired part of the ribbed portion, such as the knee of a stocking, being spliced, and the extent or run of the splicing yarn from exit marginto entrance margin of the spliced area in each course being disposed of y engagement gaged with the remainder of the knit tube as to permit the splicing yarn to be cut at or near the margins, leaving that portion engaged with and back of the ribbed fabric to be removed by a drawing operation, and preferably by a drawing operation carried out upon a number of the lightly-engaged Another object of the invention is to devise yarn feeding devices adapted to dispose of the splicing yarn extending from exit margin to entrance margin of the spliced area in relation to the forming ribbed fabric in such a way as to occasionally include the space between the faces 0 the 11 ed portion licinggarn in the Y cylinder needles, V

splicing yarn feed guide at the knitting wave; a

the stocking,

of the fabric, and to float the splicing arn behind the face-drawn or plain or ront wales of the fabric of the unspliced portions of the article which are laterally contiguous to the spliced portions.

The invention will now be described with reference to specific instances of the fabric, method, and apparatus for making the fabric and practising the method shown b in which:

Fig. 1 is a side elevation of a ribbed instep stocking containing splicing of the kind mentioned;

Fig. 2 is a face diagram in elevation of a portion of the fabric, showing the area 2,

Referring now to Figs. 1, 2 and 3 the stocking 1 may have any pattern of r bbed leg, WhlCh may have any usual or desirable type of welt at the top, and may be provided with any usual or desirable fashioned heel and toe pockets 5,5. The ribbed structure characteristic of the leg 1 extends without change from the line 6 over the instep portion of the stocking 7 and thence to the top of whereas the ribbed construction at the ck of the leg 1 of the stocking extends from the line 8 above the heel up the leg. The sole ortion 9 and the area 10 above the heel at the ack of the ankle are plain fabric to the marginal ribbed waleof the instep port on 7 ,in a lateral sense, and any desired portion of the sections 9 and 10 of the fabric may be provided with splicing reinforceway of- 'illustration in the accompanying rawings,

ment, extending, for example, from the toe pocket 5 to the line -12 above the heel, the sectional splicing having a lateral margin at the body yarn a: continuous with the body yarn for the instep section 7 this, for example, may be a light or heavy silk or cotton yarn. In the sole portion 9 the yarn a: is accom anied by and interknit in each loop with a splicing supplemental yarn 3 At the line 13 this splicing yarn 3 is taken out of interknitting relation with the yarn :v, and caused to float infront of the rib wales r, 1:, etc. and behind the face wales a, a, a etc.

As best shown in Figs. 3 and 5, this may be done by causin the splicing yarn to pass out of positionto e taken by the hooks of that set of needles first to knit, e. g. 'the,cylinder needles n, and bycausing. the splicing arn to'lie exteriorly to the loops 1' of the ribbed wales, and interior of the loops a of the face wales as these lie in the hooks respectively of the dial or rib needles d and of the needles n. As best shown in Fig. 3, theresult of this is to cause that portion of the yarn y extending around the inside. of the inste of the illustrative stocking'to be caught in front of the dial loops r, 1-, etc. of \the-ribbed section .of the knitting.

These results are accomplished as bestshown in Figs. 4 to 8 inclusive by providing e a rib knitting machine, as shown, of'the type illustrated insaid application for patent of Robert W. Scott, Serial No. 559,506, Patent No. 1,641,554, with the splicing yarn guide F adapted and arranged to be operated substantially in accordance with the disclosure of the patent to RobertW. Scott, No. 1,256,-

and including for this purpose a longitudinally and laterally movable thrust bar',460, adapted and arranged to co-operate with a segmental cam 295 on a rotating part of the machine to lift,

the splicing yarn guide F during the passage of the segment 7 of the illustrative stocking to an upper position of the yarn feeding en of the guide F Fig. 6, and as shown in plan in' Fig. 4. Whenever the thrust bar 460is longitudinally lifted, then the inward end of the splicing yarn guide F is carried upward and inward further, substantially to the position indicated in dotted lines in Fig. 8. When the thrust bar 460. is neither thrown outward nor lifted, the splicing yarn position illustrate in Fig. 7.

illustrated in run lines in f guide F is in the operative In order to induce the splicing yarn 3 taken out of knitting relation upon an elevation of splicing yarn guide F to the position show! in Fig. 6 to acquire the described relation to the ribbed fabric, the machine is provided,

and having a stop screw 23 to engage the upper surface of the latch ring 550 of the machine. The position of the lever 20 is such as to cause it when in its lowermost position, as induced by a tension spring 25, to position the lower end of an auxiliary splicing yarn positioning instrument 26 as illustrated in Figs. 5, 7 and 8. The positioning instrument 26, referring now to Figs. 4 and 6, may operate just above the depression wave in the cylinder nee dles n, and, in the direction of rotation of the needles n at a point ahead of the place of projection of the dial needles (1 following the indrawing movement of the dial needles to knit.

The instrument 26 is provided at its under side with a notch 27 which, because of. the above mentioned dispositions, is caused to receive the splicing yarn withdrawn by the moderate upward motion of the splicing yarn guide to the placeillustrated in full lines in Fi' 6.

Bec ause of the relative heights of the parts, their relative motion to each other, and the relationship of the partly elevated splicing yarn guide to the needles d and other instruments carried by the dial D of the knitting machine, the intervention of the instrument 26 is desirable to hold the splicing yarn outwardly and downwardly, see Fig. 4, to make sure of such a position for the tangential run f of the splicing yarn as will inevitably take it into the space in front of the loops r,'abovethe loops a, and inside of the needles n. a

While I may relay upon an instrument such as that shown at 26 to accomplish this, I prefer to insure the operation of the instrument 26 to this effect by providing in the needle dial jacks 30 having butts 31 and downwardly beveled ends '32, which may be placed and moved in dial grooves intervening between those occupied by the dial needles ()3, as shown, and which will have the effect, particularly as the jacks 30 in succession pass into contact with the tangential run 3 of the splicing yarn, to ride down and depress the splicing yarn beneath the level of the loop drawing hooked elements d of the two-part dial'needles d, of which the cast-ofi' elements d are about to be projected beyond the idle position shown in Fig. 5.

Referring to Figs. 6 and 11, the cylinder.

needles are depressed for knittin to their lowest point at-the radial plane-k; and the dial needle parts 03 are withdrawn to their innermost position by dial stitch cam 10 at the radial plane 1), 4;. Following the plane k, k, the dial needle parts 01 are projected by the cam groove at 16, Fig. 11. By causing the butts 31 of-the jacks 30 to be actuated by this groove 16 the desired projecting motion of the jacks 3O preceding and following the most withdrawn position of the dial needle parts at is effected. If the dial needles are single needles, instead of two-part needles, the jacks 30 may be actuated by any suitable dial cam groove giving them an outward motion inthe same relative position.

While it conduces to certain operation to move the jacks 30 radially as mentioned, in-

some cases the jacks may be fixed in projected position and perform the same function of riding down the withdrawn splicing yarn to a position below the outwardly moving dial needles, and above the loops carried by these dial needles. v

Vhen ever the splicing yarn guide F is carried upward out of action, for example at the line 12 of Fig. 1, in order to cause cessation of splicing, the lever 20 is lifted by contact of the yoke 22 with the top edge of the splicing yarn guide F and the instrument 26 passes to the dotted line position shown in Fig. 8. At this time the splicing yarn fl/ floats over the top of the dial cap d and into the position shown in dotted lines in Fig. 4 in respect to the margin of the dial and its instruments, and when in this position the splicing yarn is preferablyclamped by the clamp c and cut by the shears 16.

Referring now to Figs. 1, 7 and 10, when it is desired to. splice the stocking sectionally elsewhere, for example at the area 15, at the knee, Figs. 1 and 10, the splicing yarn y may be fed to the appropriate segment of the needles, and elsewhere engaged between the 'rib wales, such as r and the face wales a,

Fig. 10, and that part of the circumference merely engaged in the rib Wales may be removed subsequently; by severing at 'w, 'w in the way explained above, for instance.

When the front part of the stocking is spliced, as at 15, the parts are operated to cause the yarn guide F to occupy'the tion shown in Fig. 7 during passage 0 the segment of needles to be spliced. This may be done by altering the relation of the cam 295 to the rotating part carrying it or operating the bar 460 or the splicing yarn guide by another difierently'timed connectiom.

When a stocking has been knit. and removed from the machine, the splicing yarn extending across the instep in floats y may be left in the stocking, unless the stocking is of such light and transparent structure as to make its removal desira le, being sufliciently slack Where it is not interknittedto avoid limiting any necessary lateral stretch of the unspliced segment. If the floated yarn is to be removed, a recommended procedure is to cut all of the yarns 3/ at 'w by a suitable severing instrument inserted between the rib loops in- Wale r and the marginal no osiwales r, 1', etc. until all of the runs of the yarn 3 behind the instep'or other unspliced segment have been removed from engagement, and then to cut the freed splicing yarn floats at w in any usual way of trimming off splicing yarn floats. If desired, the floated splicing yarns may be out instead on the in-- step side of the first rib wale of the instep fabric beyond the margins of splicing on each side. Or, as shown in Fig. 9, the splicing may be arranged to extend beyond the plain knit segment, such as the sole 9, into the adjacent one or more rib Wales a, r etc. of the ribbed segment. In either case, the cut ends of the sp icing yarn are favorably placed to avoid working out of the fabric to the face surface.
