(ci. cfs- 192) This invention relates to elastic fabrics; and it a loop 2l at the front of the fabric formed from has reference more particularly to elasticffabrics the yarn I4 and a substantially opposite loop 22 especially suitable for the manufacturelof corformed at the back of the fabric from the yarn sets and the like.

The loop chains II, I2, it will be observed, are In the modified fabric of Figs.

A further variation of the back ofthe fabric from the yarn I4, whereas in modified fabric of Figs. II'and IV will be noted in the chains I2 the said wefts are engaged between the somewhat different construction 'of the mar- 55 gin 21a wherein the weftsv Illa are engaged throughout between the registering loops of the successive double courses of the knitting. In vall other respects the modified fabric is identical with the first described form, and I have accordingly designated all corresponding parts which have ynot been specically'mentioned, with the same reference characters hereinbefore employed except for the addition in each instance of the letter a for the purposes of distinguishment.

It is to be understood that I do not Vconsider myself limited to the precise details of construction and arrangement herein set forth since various other modifications can be made within the scope of theappended claims without departing from the spirit of my invention.

Having thus described my invention, I claim:

1. Porous warp-knit fabric suitable for corsets and the like, having spaced parallel strands of elastic yarn incorporated between opposite loop chains of inelastic yarns respectively at the front and the back of the fabric, said chains being connected laterally in the intervals between adjacent elastic strands throughout the width of .the fabric with their connecting portions deiining the interstices of the fabric.

2. Porous warp-knit fabric suitable for corsets and the like, having spaced parallel weftsof relatively heavy elastic yarn incorporated. between opposite loop chains of inelastic yarns of finer gage respectively at the front and the back of the fabric, said chains being connected laterally in the intervals between adjacent elastic strands with their connecting portions defining the in-v terstices of the fabric.

3. Porous warp-knit fabric suitable for corsets and the like, having parallel strands of elastic yarn inlaid between registering embracing loops of laterally spaced double loop chains, adjacent elastic strands being held in spaced relation and the interstices of the fabric defined by laterally connected registering loops intermediate the embracing loops aforesaid of the double chains.

4. Porousv warp-knit fabric suitable for corsets and the like, having spaced parallel strands of elastic yarn incorporated by loop chains connected laterally in the intervals between` adjacent elastic' strands with the connectingportions defining the interstices of the fabric, each such chain being knit from two warp yarns with the elastic 'strands inlaid between embracing loops at opposite sides of the fabric. f

5. Porous warp-knit fabric suitable for corsets and the like, having spaced parallel strands of elastic yarn incorporated by loop chains connected laterally in the intervalsbetween adjacent elastic strands with their connecting portions deining the interstices of the fabric, each such chain being knit from two warp yarns with the elastic strands inlaid between registering ernbracing loops of the respective warp yarns, and said loops being respectively disposed at opposite sides of the fabric in adjacent chains.

6. Porous warp-,knit fabric suitable for corsets and the like, comprising a portion wherein spaced parallel strands of elasticyarn are incorporated by loop chains of inelastic yarns, said chains' a solid portion wherein the elastic wefts are bound togetherin non-spaced contiguous relation by'said loop chains.

8. A double faced knitted fabric comprising elastic weft threads disposed between the opposite facesof the fabric and secured in place by'separate pairs of warp thread loop chain portions extending from face to face of the fabric-and forming said opposite faces of the fabric.

9. A double faced elastic 'fabric comprising substantially similar opposite faces including adjacent separate loop wale portions formed by successive loop courses, extending alternately between said faces and elastic wefts bound in predetermined courses respectively between the loops.

of the opposite faces of the fabric formed by said courses. i

l0. A double faced knitted fabric comprising elastic weft threads disposed between the opposite faces of. the fabric and securedfin place by separate pairs of warp thread loop chain portions extending frorn face to face of thefabric and forming said opposite faces of the fabric.

11. A double faced elastic fabric comprising substantially similar opposite faces including adjacent'separate loop wale portions formed by successive loop courses, and elastic wefts bound in predetermined courses respectively between the loops of the opposite faces of the fabric formed by said courses, said wefts being tied in position in said fabric by warp threads crossing said wefts and forming loops in each of said successive wale loop course port/ions on the opposite faces of the fabric respectively.

I l2. Porous warp-knit fabric suitable for cor-` sets and the like, having parallel strands of elastic yarn inlaid between registering embracing loops of vlaterally spaced double loop chains, ad-

. jacent elastic strands being held in spaced relation and the`interstices of the fabric defined by laterally connected registering loops intermediate the embracing loops aforesaid of the double chains.
