GEORGE W.

GOETSCH, F ELKJLNS PARK, PENNSYLVNIA, ASSIGNOR TO QUAKER HOSIERY COMPANY, 0F PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA ANTRAIVEL WELT JUNCTURE FOR STOCKINGS Application led July 22, 193G. Serial No. 469,667.

This invention relates to anti-revel welt junctures for knitted articles such as stockings,l as well as to methods of forming such junctures..

junctures for stockings had to be formed-entirely by hand through lateral displacement 1oft loops of the initial course of the knitting by manipulation of the transfer bar and as an incident lo to closing of the welt upon the needles of the producing machine. This operation was extremely tedious particularly in connection with fine gage work and therefore required the employment of skilled knitters, consumed and `1 added materially to the cost of production of the stockings. j j

The chief aim of my invention is to overcome the above .recited drawbacks ofprevithrough the welt of the stocking showing the location of the juncture.

Fig. III is a diagrammatic fragmentary View on a larger scale showing the manner in which fabric loops are taken from alternate needles ot' the machine by the points otl the picot or lock stitch attachment.

F ig. 1V is a view similar to Fig. Hl showing how the loops taken as aforesaid by the points of the picot or lock stitch attachment, a@

are transferred to adjacent needles of the machine to form the antl-ravel juncture.

Figs. V, Vl, Vll and VIH are diagrammatic views showing the manner in which the needles, knockovers and sinkers of the m21-, @5

chine andthe points oil the picot or lock stitch attachment cooperate in forming the anti-revel welt juncture.

Fig. IX is a fragmentary view showing the ous practice by making'po'ssible the formation 21! forth, by employmentof the picot or lock lneedle bar of the machine and the point bar m ofthe picot or lock stitch attachment, and further illustrating the manner of cooperation between these parts to form the antiravely juncture; and

Fig. X is a diagrammatic fragmentary .w

of anti-ravel welt junct'ures upon full` fashioned knitting machines without increase in the cost of production of the stockings. This' desideratum I secure, as hereinafter fully s qt form a narrowing cycle,

.35. of such transferred loops with the doubled loops on1 said adjacent needles to form the anti-ravel barrier.

A further objectofmy invention -is to predetermine as the result of an automatic opero ation of a stocking knitting machine, an

anti-ravel welt juncture which is neat and regular in appearance, inconspicuous and absolutely eiective against the continuation ot 5 runs, originating in the garter top of a stocking, down through the leg or body portion'. In they drawings, Fig. II isa view of a full fashioned ladies stocking with my novel anti-ravel juncture conventionally indicated.

io Fig. II is a diagrammatic sectional view view showing the character otl my novel antlravel welt juncture.

The stockingI delineated in Figs. I and H has its welt W joined to the leg or body portion B by my improved anti-ravel juncture which is conventionally indicated in these figures at 1t). The character of the welt juncture is shown diagrannnatically in Fig. X wherein the numerals ll and 12 designate theinterlooped terminal courses of 'the Welt. 85 The course l1 is stippled for the purposes of distinction and constitutes the last knit course ot the welt fabric; While the course 12 constitutes the first knit course of said welt fabric. As.'shown, each alternate loop lla of the 90 last knit course 1l ofthe welt fabric is crossed with the corresponding loop 12a of the iirst knity course l2, and, moreover, interlooped with the adjaeently allocated doubled loops 1lb, 12b of the two welt juncture courses l1, 95

l2. Obviously, by such' crossing and interloopingvor1 alternate loops of one of thev `terminal courses of the welt Jfabric with the intervening doubled loops of the two terminal courses at the line of juncture results in an effective barrier to prevent runs originating in the welt or garter top from running down into the leg or body portion of the stocking.

A welt juncture having the characteristics just described may, in accordance with my invention, be readily made on a full fashioned hosiery machine equipped with a picot or lock stitch attachment, i. e., an attachment which includes, as shown in Fig. IX, a longitudinally-shiftable bar A having points P to correspond 4with alternate needles of a series N of the knitting machine.

The method of procedure in forming a stocking welt with my improved anti-ravel juncture i's as follows: The stocking is started by knitting the first course 12 loose as ordinarily; and a sufficient length of fabric thereafter knit for the Welt IV whereof the last or terminal course 11 is preferably knit loose like the first course 12. The machine is then set for narrowing by shifting of the cam shaft in the known way; and the fabric is then folded to close the welt by indiif'idually engaging the loops 11a of the last knit course 11 of the welt fabric over the needles N of the machine through -manipulation ofthe welt bar-likewise in the knownmanner. However, instead yof pressing the newly impaled loops 11a of the course 11 down along the shanksfof the needles and onto the noses of the sinkers S of the machine as ordinarily, I keep them up in the tops of said needles as Shown in Fig. V. The machine is then Started to perform a narrowing cycle with incidental forward movement of the sinkers S under influence of the catch bar of the machine, and descent `of the bar A to bring its points P to the level of the beards of alternate needles of the series N, as shown in Fig. VI, while the sinkers gradually recede. In this connection it is to be noted that the loops 12a of the 'terminal course 12 of the welt uppermost on the needles is supported on the top nibs of the sinkers S until the points P have penetrated the loops 11a of the terminal course 11 lowermost on the needles andl resting upon the knock-overs K. As the sinkers S continue to recede, the upper layer of the welt is pulled down by the needles N until it rests upon the knock-overs K as shown in Fig. VII. After completing the dip, the needle points P rise to the positions shown in Figs. VIII and IX with the result that the loops 11a are drawn over the loops 12a. Then, withlateral shifting of the point. bar A in the direction indicated by the arrow in Fig. IX, the loops 11a are transferred laterally to a position immediately above. the tops of the adjacent needles of the series N and finally engaged with said needles as the 'narrowing cycle is completed.

Thus through employment of the picot or lock stitch attachment of a full fashioned knitting machine after turning of the welt,

it is possible to form an effective anti-ravel juncture automatically without adding to the cost of production of the stockings. A juncturev so made is devoid of irregularities, and,

although inconspicuous, distinguished by a terminal loops of the other thickness of the welt fabric; and then transferring the loops so drawn laterally and interlooping them with adjacent doubled terminal loops of the superposed Welt layers.

2. The methodofjforming a. ravel proof stocking welt juncture by drawing alternate loops of the last knitted course of the Welt fabric over the corresponding loops of the first knitted course of the welt fabric after welt closure vand then laterally transferring the loops so drawn and interlooping them with the adjacent superposed loops of the said first and last knitted courses of the welt.

3. 'llie methodof forming a ravel proof welt juncture in stockings upon a hosiery knitting machine, by drawing the nethermostloops on alternate needles of the machine, after welt closure, over the uppermost loops on said needles; and then transferring the loops so drawn laterally to adjacent needles.

4. 'lhe method of forming a ravel proof welt juncture in stockings upon a f'lat hosiery knit-ting machine equipped with a picot or lock stitch attachment, by drawing the netherniost loops on alternate needles of the machine, after welt closure, by means of the points of said picot or lock stitch attachment, through the uppermost loops on said alternate needles; and then laterally transferring the loops so drawn to adjacent needles through shifting of the points of said picot or lock stitch attachment.

5. 'lhe method of forming a ravel proof welt juncture in stockings upon a flat full fashioned hosiery knitting machine equipped with a picot or lockstitch attachment, by setting the machine for narrowing at the completion of the welt fabric; then closing the welt by transfer of the loops of the first knit course on the welt bar to the needles of the machine, but keeping' such loops in the tops ofthe needle; and then causing the machine to perform a narrowing cycle. with attendant drawing of' the netherniost loops or the loops of the last knitcourse. of the welt fabric on alternate needles, over the uppermost loops or the loops of' the first knit course of the welt fabric on such alternate needles, b the points of the picot or lock stitch attac iment, and transfer of' the loops so drawn to adjacent 4needles through lateral shifting of the picot points.

6. A stocking with a ravel proof welt juncture wherein alternate loops of one of the terminal courses of the welt fabric are crossed with the corresponding loops of the other terminal course of the welt fabric, and interlooped with the dimm doubled hops of the superposed terminal courses along the welt juncture.

In testimony whereof, I have hereunto u signed my name at Philadelphia, Pennsylvania, this 18th da of Jul 1930.
