STRiPED KNITTE FABRC.

SPECIFICATION forming part of Letters Patent No. 618,017, dated January 17, 1899.

Application filed Marchi, 1898. Serial No. 672,179. (No specimens.)

To @ZZ whom t may; concern:

Be it known that I, HARRY SwrncLnHUns'r, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvem ents in Striped Knitted Fabrics, of which the following is a speciiicatin. My invention relates to an improvement in that class of knitted fabrics in which trans- -verse stripes are produced bythe use of dif- Io ferent-colored yarns controlled by movable guides, so that one knitting-yarn may be moved out of operative relation with the needles when another is brought into operative relation with tne same, the object of my i5 invention being to prevent cutting of the stitches at the point where the change ot knitting-yarn is effected.

In the accompanying drawings, Figure 1 is a diagram illustrating the disposition of the so yarns in a fabric of the lcharacter to which my invention relates, and Fig. 2 is an exaggerated view of part of the fabric illustrating myr improvement.

In that class of knitted webs having trans- 2 5 verse stripes formed by changing the color of the knitting-yarn it frequently happens that at the point where the change is eiected both yarns will be fed to a few of the needles, and' if the fabric is knitted very stiff or of very 3o close texture these two yarns will overload the needles and will cause 4rcutting of the stitches, so as to produce defective fabric.

In Fig. 1 of the accompanying drawings the successive courses ofstitches in a tubular fabric of the character to which my invention relates are represented by simple convolutions of yarn, the four lower courses being composed of a dark yarn l and the three upper courses of a light yarn 2, the unused yarn iioating from stripe to stripe on the inside of the fabric, and it will be noticed that where the yarn changes the two yarns lie together for a short distance, as shown at 3, and in the knitted fabric double stitches are produced lthroughout this portion of the course, as

shown in Fig. 2.

Ii the fabric is very closely knitted or of very fine texture, the application of these two yarns to certain of the needles will put such a strain upon said yarns as to break them or 5o the yarn in the preceding course, which, bcing tightly knitted, cannot yield to the pull upon it, and in order to overcome this objection I form longer or slacker stitches upon those needles to which the two yarns are likely to be applied, this result being eliiected by drawing said needles down below the normal draw-down point while the two yarns are being applied thereto and also, by preference, at corresponding points in the preceding and following courses, so that not only are the double stitches themselves slnckenecl7 but there are slack stitches in the two adjoining courses, as shown in Fig. 2, thus providing in that portion of theqfabric where the yarns are 6 5 doubled the elasticity necessary to prevent breakage of the yarn.

The slackening of the stitches in the course following that in which the yarn is doubled may be omitted, if desired, as the stitches in 7o which the double yarn is being knitted and the corresponding stitches in the preceding course are those upon which the strain is exerted.

Itmight even be possible. to `knit loosely only the stitches in the course preceding the double-stitch course,in which case the doubleyarn stitches might draw through the stitches of said preceding course, so as to prevent breaking of the yarn but I prefer in al1 cases to slacken both the double-yarn stitches and' the corresponding stitches in the preceding course.

My invention is applicable to that class of fabrics in which the striping fis eiiected by breaking off one knitting-yarn and running in another, as in Asuch case, also, there is a lap of the two yarns at the point where the change is elected.v

Having thus described my invention, I claim and desire to secure by Letters Pat-V entl. A knitted fabric having transverse stripes formed by the substitution of one knitting-yarn for another so as to produce double- 95 yarn stitches at the point where the change is effected, and having in the course preceding that in which such change is elected,

stitches engaging said doubie-yarn stitches,

and longer or slacker than the Stitches in the stripes formed by the substitution of one knit-- tin g-yarn for another, and having at the point where the change of yarns is effected, donbieyarn stitches longer or slacker than those in the body of the fabric, said double yarn stitches engaging with long or slack stitches in the preceding con rse,substantiaiiy as speciieii.

l5. A knitted fabric having transverse stripes formed by the substitution 0f one knitting-yarn for another, and having at the point where *he change of yarn is eieeted, doubleyarn siiiches longer or slacker than those in the body of the fabric, said double yarn stitches engaging with long or slack stitches in 'the preceding and following courses, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
