KNITTED FABRIC.

SPECIFICATION forming part of Letters Patent No. 709,827, dated September 23, 1902.

Application filed February 25, 1902. Serial No. 95,505. (No specimens.)

To all whom it may concern:

Be it known that I, ROBERT W. SCOTT,a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Knitted Fabrics, of which the following is a specification.

My invention consists of a fabric comprising two webs practically independent of each other, but held or tied at intervals by yarns 1o difierent from those which constitute the webs, the two webs lying closely together, so as to provide a double web joined at the desired points. 7

The two views in the accompanying drawings illustrate different methods of securing together the two webs in accordance with m y invention.

The fabric consists of two single webs, each preferably tubular and one overlying the other, as shown at 1 and 2, these webs being held or tied together at the desired points. For the purpose of thus holding or tying together the two webs I employ yarn or yarns separate from those constituting the webs and 2 5 forming courses which may be parallel either with the needle-wales or the courses of said webs, the tying-yarns overlying Wales of one web and forming loops or stitches in wales of the other web, or, if desired, forming loops or stitches in wales of both webs.

In Figure 1 of the drawings I have shown various ways of manipulating the tying-yarn so as to form courses in line with the needlewales of the fabric. Thus the tying-yarn 00 has loops engaging a need le-wale of the back web and overlies sinker-wales of the front web in its passage from loop to loop, a tying-yarn 00 forms stitches in a wale of the back web instead of simple loops, a tying-yarn 00 forms.

In the fabric shown in Fig. 2 the tyingyarns instead of running parallel with the needle-wales of the fabric run parallel with the courses of the latter, the yarn 00 forming loops in the wales of the back web and overlying wales of the face web, the yarn 00 forming stitches in the wales of the back web and overlying wales of the face web, the yarn m forming loops in wales of the face web and overlying wales of the back web, the yarn x forming stitches instead of loops in said face wales, the yarn 00 forming loops in wales of both back and face webs andfloating between the tying-points, and the yarn 00 forming stitches in wales of both back and face webs and floating between the points.

Where the tying loops or stitches are formed in wales of both webs they need not be formed in adjoining courses, but may be separated by any desired 11 umber of intervening courses.

The independent tying-yarns may, if desired, be of a color different from that of the yarn of either web or may be otherwise distinguished therefrom, so as to form stripes on the surface of the fabric, thus serving the double purpose of uniting the webs together and providing a means of ornamenting the surface of the fabric. 4

The term sinker-wales, as herein employed, means those portions of the knittingyarn which extend from one needle-wale to the next.

The fabric can be produced upon a machine having two needle-carriers with one or more yarn-guides for each needle-carrier, one yarnguide or set of yarn-guides feeding yarn to the needles of one needle-carrier to produce one web and the other yarn-guide or set of yarn-guides feeding yarn to the needles of the other needle-carrier for the production of the other web.

In addition to the knitting-yarn guides there will in producing the fabric having the tying- -yarn extending in the direction of the needlegroups of needles throughout the set, the rec needle or needles engaging the yarn when a loop of the same is to be drawn, and the yarn passing clear of the needles when it is to float.

Any one or more of the different methods of tying the webs together shown in Figs. 1 or 2 may be employed, any desired number of wales or courses of the knitted web intervening between the courses of tying-yarn and any desired number of courses or wales of the knitted web intervening between the tyingpoints of said tying-courses.

hen the floating portions of the tying yarn or yarns are on the back of the fabric, these floating portions may be permitted to remain; but when a reverse construction is adopted and the floating portions of the tying yarn or yarns are upon the face of the fabric such floating portions may be removed if their presence is objectionable provided the tying-yarn has formed groups of loops or stitches in wales of both webs, so that the presence of the floating portions of the tying yarn or yarns is not necessary to hold the webs together.

Instead of disposing the tying-yarns in courses parallel with the wales the same may be disposed in inclined or zigzag courses, if desired, the tyingyarn forming a loop or stitch first in one wale and then in another wale. In fact the number and disposition of the tying-points can be varied as the character of the fabric or the uses for which it is intended may suggest.

Having thus described my invention, I claim and desire to secure by Letters Patent l. A knitted fabric comprising two webs one overlying the other, said webs being held together by a knitting yarn or yarns independent of those of which the webs are com- I posed, substantially as specified.

2. A knitted fabric comprising two webs one overlying the other, said webs being held together by yarn or yarns independent of those of which the webs are composed, and engaging with Wales of the two webs alternately, substantially as specified.

3. A knitted fabric comprising two webs one overlying the other said webs being held together by yarn or yarns independent of those composing the webs and forming loops or stitches in wales of the webs alternately, substantially as specified.

4. A knitted fabric comprising two webs one overlying the other, said webs being held together by yarn or yarns independent of those composing the webs, forming loops or stitches in wales of the Webs alternately, and floating from each group of loops or stitches to the next, substantially as specified.

5. A knitted fabric comprising two webs, one overlying the other, said webs being held together by yarn or yarns independent of those of which the webs are composed, the tying yarn or yarns extending in the direction of the courses of stitches of the knitted webs, and engaging with wales of the two webs alternately, substantially as specified.

6. A knitted fabric comprising two webs, one overlying the other, said webs being held together by yarn or yarns independent of those composing the webs, said tying yarn or yarns extending in the direction of the courses of stitches of the knitted webs, forming loops or stitches in wales of the webs alternately, and floating from each group of loops or stitches to the next, substantially as specified.

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

ROBERT W. SCOTT.
