After the knitting of In Fig. 4 is shown a stocking top slightly modithe pull course any desired number of courses of ed as compared with the stocking or half hose rib fabric I3 may be knitted for the purpose of disclosed in Fig. 1 to the extent that the knit- 50 providing a usual top. ting in of a pull course or the severing of wales Thereafter the remaining portions may be as indicated at I2, Fig. l, is dispensed with, the knitted in any desired manner and as herein disstocking top shown in Fig. 4, being provided closed a transfer is effected after which a plain with welt courses 2, rib courses 3, elastic courses les I4 0f any desired length is knitted with one 4, and other rib courses I3 which are knitted 55 in the same manner as are the corresponding courses, Fig. 1.

I f it be desired to knit in the elastic thread throughout all ofthe courses of adjacent plain and rib wales, 1 and 8, thefplain needle which knits the Wale l may be so positioned as to catch the elastic thread in its hook so that thereafter, when the said needle is moved to a position to draw its stitch over adjacent rib needles, the elastic thread will be caught and knitted in by the next following -rib needle which needle knits the wale 8. The knitting in of the elastic thread at any wale is not, however, essential but the friction between the elastic thread and the wales may be relied upon to maintain the said elastic thread in position in the fabric although an adhesive may be used to assist in the holding of the elastic thread more or less fixed with respect to its original position in the fabric.

In order properly to feed the elastic thread 5 to the needles or rather between thewales of the fabric it is necessary that the end of the elastic thread be temporarily retained by the usual or other binder, which includes a clamp and a cutter, and which binder ispreferably located upon the upper face of a dial cap when knitting rib or upon the upper or other face of a binder plate when knitting plain. However, a special form of clamping and cutting mechanism may be used if desired, but in any event it is essential that some means be provided for temporarily retaining the end of the elastic thread within the needle circle, when knitting on a circular machine, so that when the thread guide for the elastic thread 5 is dropped to a feeding position the said elastic thread may properly be fed to the needles and between adjacent or other wales of the fabric.

Although as herein disclosed the elastic thread 5 is laid between adjacent rib and plain wales, as when knitting one and one rib, vit is obvious that the said elastic thread may be bound in and held between rib and plain wales when knitting` rib fabric in proportions other than one and one rib.

The rib stocking or half hose hereinbefore disclosed may be knitted upon any plain machine to which rib tops are transferred or upon any machine adapted to knit rib and plain fabric, being preferably knitted upon a machine having a needle cylinder and a needle dial adapted to rotate continuously during the knitting of circular portions of the stocking, while the cylinder, at least, is adapted to oscillate during the knitting of heels and toes.

One method of incorporating the elastic thread 5 is to feed such elastic thread Isubstantially at the verge of the cylinder and dial and with the cylinder needles in their lowered or depressed positions so that thereafter when the cylinder needles rise to take thread and thereafter draw the same over the dial needles, the elastic thread will be incorporated in the fabric and held between dial and cylinder wales; but the preferred method of feeding the elastic thread to the needles is to feed such elastic thread below the latches of raised cylinder needles and below the level of the dial needles which are in retracted position. 'Ihereafter the dial needles are projected and the cylinder needles are moved to stitch drawing position in the usual manner and as the cylinder needles reach their lowermost position the elastic thread 5 moves to a position againstthe fabric such as indicated in Fig. 2 in the patent to Riley 630,110, August 1, 1899. The said patent toRiley discloses the first above described method for incorporating the elastic thread between the plain and rl wales of a fabric and valthough the second described method is different from that disclosed in the patent nevertheless its effect is the same in that the elastic is finally bound or held between plain rib wales.

Although as hereinbefore disclosed the elastic thread 5 is incorporated between rib and plain wales, the top 22 of the stocking may be knitted plain as shown in Fig. 5, i. e., without rib wales, and extremely loose or` with relatively long stitches. The elastic thread 5 is incorporated in the fabric by passing forward of wales 23 and back of adjacent wales 24 and, if desired, may occasionally be knitted in at one or more of the wales as Wale 25.l l

One method of incorporating an elastic thread in'a plain fabric consists in lowering alternate or other groups of needles to such a position that the elasticthread may be fed over the tops of the said lowered needles and raising the intermediate or other groups of needles to such a position that the said elastic thread may be laid against or adjacent to the shanks thereof and below the needle latches. Thereafter the alternate cylinder needles are raised to the level of the intermediate needles, the elastic thread then being back of the said alternate needles and forward of the shanks of the intermediate needles.

Another method of incorporating the elastic thread in plain fabric consists in laterally deflecting alternate or other groups of needles at the upper ends thereof and laying the elastic thread between the deected, alternate needles and the intermediate needles, the thread being laid between the needles in such a manner as to pass below the latches of the said needles. By the method of feeding elastic thread to the needles just described the said elastic thread is held between the shanks of the alternate needles and the shanks of the intermediate needles.

Regardless of the method employed for feeding the elastic thread between needles the result is the same, and thereafter as the needles descend in the usual manner to knit the main thread or threads, the elastic thread becomes incorporated in the fabric and is held between the alternate or other groups of wales and the intermediate wales.

In any case the elastic thread, where it is not knitted in, passes between the wales in such a manner as to become part of the fabric.

Preferably the elastic thread 5 is fed to the needle under as light a tension as possible and if desired the said elastic thread may be measured out or fed to the needlesv by means of rotating rolls whereby denite lengths of such elastic thread may be fed to the needles during the knitting of each course; in other words, if desired, the elastic thread may be fed to the needle by means of a so-called positive feed.

The invention hereinbefore disclosed, when used in connection with hosiery, is applicable either to a half hose or to a stocking of. full length and although in certain of the claims reference is made to a stocking nevertheless there is no intention of thereby limiting the invention to a full length stocking the term stocking being used in a generic sense.

1. A knitted stocking the top whereof is composed of a plurality of rib courses having incorporated therein an elastic thread, such elastic thread being held between rib and plain wales and knitted in at one or more wales and in one or more courses.

2. A knitted stocking the top whereof is composed oi a plurality of courses having incorporated therein an elastic thread, such elastic thread being held between adjacent wales but not knitted and knitted at one or more wales and in one or more courses.

3. A plain knitted fabric having incorporated,

therein an elastic thread, the said elastic thread passing between and being held by adjacent wales of the fabric but not knitted and being knitted into the fabric at one or more of the wales in one or more of the courses.

4, A plain knitted stocking provided with a loosely knitted top in some of the courses of which an elastic thread is incorporated, said elastic thread passing between and being neld'by adjacent wales of the fabric but not knitted and being knitted into the fabric in one or more of the courses.

5. A knitted stocking the top whereof is composed of a plurality of knitted courses having incorporated therein an elastic thread, said elastic thread passing between and being held by adjacent stitches but not knitted in some of the courses and being knitted into the fabric where it does` not pass between adjacent stitches in the manner aforesaid.
