RAVEL STOP.

4 Application filed December 14, 1927. Serial No. 239,856. r

This invention relates to ravel stops for knitted fabrics or apparel,-f or example ladies stockings-to prevent runs having their origin in the welted garter tops from 5' continuing down into the leg portions. Such ravel stops have long been produced in stockings knit on flat knitting machlnes through engaging each of the loops of the 1n1t 1al course of the fabric over several needles 1ncidentally to turning the welt, and ust prearatory to commencement of the stocking lbg. W1th very fine gauges such as now generally demanded in stockings, manipulation of thewelt bars in displacing the fabric loops for the purpose explained is extremely tedious and exacting, and, in the event that any of the fabric loops are dropped, entails either discarding the entire fabric previously formed, or results in seconds which must be disposed of at a loss.

The chief aim of my invention 1s to oyercome the above recited drawbacks of previous practice through provision of a ravel stop which is in itself unique, and which-1s very easil formed so that the necessity for employing especially skilled and expenslve help 1s dispensed with. 0

One way in which the forego ng and other advantages may be readily attained in practice will be apparent from the detailed description which follows when taken in connection with the drawings whereof Fig. I shows a welt top of a ladies stocking conveniently embodying the ravel stop of my invention.

Fig. II is a diagrammatic detail view showing a section through the upper part of the stocking.

Fi III is a fra mental-y illustration showing t e texture o the fabric within the dotted rectangular area A in Fig. I and as v ewed from the inside of the stocking.

Figs. IV, V, VI, VII, VIII and IX are diagrammatic views showing successive steps in the formation of the ravel stop.

The stocking depicted in Fig. I of these 11- lustrations will be observed as of the full fashioned variet such as are produced on flat knitting mac ines. Its garter top or welt W isjoined to the body or leg portion L by the improved ravel stop which is conventionally represented at 10 in Figs. I and II. In carrying out my invention, I initially knit a course 11 (Fig. IV on the needles N of the knitting machine an engage alternate sinker loops 11 of such course, as shown in Fig. V, with a welting bar 12 having half as many hooks 12' as there are needles in the knitting machine. The machine is then restarted (incidentally to which the uncaught sinker loops are drawn out as shown in VI as a consequence of pull upon the bar 12), and a second course 13 knit as in Fig. VII, whereof I engage, with the welting bar hooks 12, alternate sinker loops 13 in wales neighboring those initially caught in the first course, the last described step being shown in Fig. VIII.

Thereupon I proceed with the knitting to.

produce a length of plain fabric for the welt.

In this connection it will be observed from Fig. IX that the doubled loops 11*, 13 on the welting bar hooks 12 equalize themselves and that the two courses first knit lose their identity as a consequence of being merged under pull of the welting bar. Upon completion of the fabric for the welt, the latter is turned by transfer of the doubled loops 11*, 13* on the hooks 12 of the welting bar 12 to alternate needles of the machine, i. e. said loops are superimposed upon those then held by the needles. Knitting is then resumed in the usual way to form the body of the stocking. The texture of the finished ravel stop is shown in Fig. III as it appears when viewed from the inside of the stockings, the interlooping of the yarn being readil traced with the aid of the reference numera s which are the same as those employed for the corresponding parts in the other figures.

By forming the ravel stop in the mannerdescribed, a very effective barrier is produced against the possibility of runs having their origin in the welt from entering the body or leg of the stocking, since the crossed loops 11*, 13 constituting the band 10 (Fi III) have their roots in adjacent wales of t e welt and their heads anchored in adjacent wale loops of the fabric body. The ravel stop is moreover easily formed by thelknitter by virmost, only two the formation of the antiravel is delayed until the welt is turned (as is ordinarily practiced in the art), the dropping of loops at that time necessitates discarding of the entire fabric of the welt or results in the production of an imperfect stocking.

Having thus described my invention, I claim:

1. The method of forming a ravel stop in welted knit fabrics by doubling alternate loops of one course with alternate neighboring Wale loops of another course preparatory to knitting the welt fabric, and subsequently transferring the doubled loops to the needles of the machine.

2. The method of forming ravel stops in welted knit fabrics which comprises initially producing a ravel stop band by doubling alternate loops of one course with alternate neighboring wale loops of another course,

knitting the fabric for the welt, and uniting 1 the doubled loops of the ravel stop band wit the last course knit before continuing with the formation of the main or body portion of the fabric.

3. The method of forming a ravel stop in welted knit fabrics which comprises knitting an initial course of loops, holding loops of this first course while knitting a second course,

,doubling the held loops of the first course and loops of the second course, knitting a length of fabric for the welt, and superposing the loops doubled as aforesaid upon the loops of the last course knit to close the welt before proceeding with the knittingof the main or body portion of the fabric. 7

4. The method of forming a ravel stop in welted fabrics by knitting an initial course of loops, holding loops of this first course while knitting a second course, doubling the held loops of the first course with neighboring Wale loops of the second course, knitting a length of fabric for the welt, and superposing the loops doubled as aforesaid upon the loops of the course last knit to close the welt before proceeding with the formation of the main or body portion of the fabric.

5. The methodof producing a ravel stop in welted fabrics by knitting an initial course of loops, holding alternate loops while knit ting a second course, doubling the held loops of the first course with alternate neighboring wale loops of the second course, knitting a length of fabric for the welt, and uniting the loops doubled as aforesaid with alternate loops of the last course knit to close the Welt before proceeding with the formation of the main orbody portion of the fabric.

6. The method of forming a ravel stop in welted fabrics on fiat knitting machines which comprises knitting an initial course of loops on the needles of the machine, engaging loops of this first course on the hooks of a welting bar, knitting a second course on the needles, engaging loops'of such second course with the engaged loops of the first course on the welting bar hooks, knitting a length of fabric for the welt, and turning the welt by transferring the doubled loops on the welting bar hooks to the needles of the machine before continuing with the formation of the main or body portion of the fabric.

7. The method of forming a ravel stop in welted fabrics on flat knitting machlnes which comprises knitting an initial course of loops on the needles of the machine, engaging loops of this first course on the hooks of a welting bar, knitting the second course on the needles, engaging the loops of such second course in wales neighboring those occupied by the engaged loops of the first course on the welting bar hooks, knitting a length of fabric for the welt, and turning the welt by transferring the doubled loops on the welting bar hooks to the needles of the machine before continuing with the formation of the main or body portion of the fabric.

8. The method of forming a ravel stop in welted fabrics on flat knitting machines which comprises knitting an initial course of loops on the needles of the machine, engaging alternate loops of such course on the hooks of a welting bar, knitting a second course on the needles, engaging the loops of 'such second course in wales neighboring on the welt bar hooks to the needles of the machine before continuin with the formation of the main or body portion of the fabric.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania, this ninth'day of December, 1927.

GEORGE W. GOETSCH.
