Application filed March 2,1, 1912. Serial No. 685,212.

ZIO all whom 'it may poncem B it known that I, SIMON FRIEDBERGR, apcitizenof the' United States,.vresid ing at Philadelhia, county of Philadelphia, vand ennsylvania, have invented a new. and useful Improvement inKnitted Fabrics, of which the following is a full, clear, andl exact description, reference' being had to the' accompanying drawings, which form a part of this speoication. l f The object of my invention is to-produce a fabric adapted especially for use in making laundry bags and analogous knitted articles. Insuch articles it is highly desir able that the fabric of which it is composed 'shall not unravel as a -result of the rough handling to which it is exposed. It is also desirable that the fabric Yshall be of such elasticity that when .exposed to pulling stresses in different directions, it will give .in differentdirec'tions to a substantially uniform extent. J

In the drawings: Figure l isa plan view of the fabric as it appears to the eye; F ig. 2 is a detail view of the fabric on an enlarged scale.

The fabric, which is intended to be manufactured on the ordinary traverse warp Inachine, is composed of three sets of threads, two filling warp threads and one binding warp thread. The two sets of filler threads are marked respectively a, a, a2, etc. and ZJ, 5', b2, While the binder threads are marked @650,0 etc.

It will be observedthat the linished fabric, generally speaking, comprises longitudinal bars a, fr', m2, m, etc.,4 of interlooped threads composed of all three sets of threads, and transverse bars y, y', y2, y, etc. of iioating threads composed'of the two sets of filler warps. More specifically it-will be observed that the iiller thread a (starting,- say from point m) extends transversely in one direction to the longitudinal bar thence' directly forward between adjacent intersections of thevlongitudinal bar m and the transverse bars y and y', thence transversely in the opposite direction to the adjacent longitudinal bar thence is formed into a loop at the intersection of longitudinal bar w and transverse bar y', thence extends forward, in the course of which it is reversely curved upon itself, to the intersection of bars m" and 'l2/2, and thence transversely toward longitudinal bar :v Following the ller thread b from the same point m, it will be observed that it extends transversely in one direction to the longitudinal'bar m, thence is formed into a .loop at the intersection of longitudinalbar and transverse' bar y, thence extends forward, in the course of which it is reversely Acurved upon itself, to' the intersection. of bars and y, thence transversely in the opposite direction to the longitudinal bar w', thence directly forward .between adjacent intersections of the longitudinal bar and the transverse bars y and y2, and thence'transversely toward Llongitudinal bar i Following the binder thread c from the point n,-the same extends forward through the rloop of the thread 6, at the intersection of bars,v m and y, thence forward under thread and thread. @,thence through one pocketof the reversely curved portion vof thread b', thence back over the neck of said loop of threadb, thence forward successively over thread andnder Ithread a and through the loop of thread a at the intersection of bars and '3`/, thence back successively over and'under thread b and through the other pocket of the reversely through said loop of thread a, thencefor- Acurved portion'of thread b, thence again ward under threads o and thence through one pocket ofthe reversely curved portion ofA thread a, thence back overfthe neck'of 'saidioop of thread a, .thence for.

versely curved portion of thread a.

From the foregoing description it will be understood that the threads are so looped together thati'eif any one thread should be broken or cut at alny point, any attempt, by pulling the loose fend,- to unravel the fabric, would result in" tying a knot or knots in the threads and thus even more securely securing the several threads together.

Having now fully. described my invention, what I claim and desire to protect by Letters Patent is:

1. A knitted fabric composed of iiller warp threads each extending supcessively transversely and forwardly, throughout the length of the fabric, each of said threads, in its alternate forward extensions, being successively formed into a loop and reversely curved, and a binder warp thread extending through and around the necks of the vand through theother pocket of the re-4 noso, reo

loops, and through the pockets of said re- Versely curved portions, of the filler Warp threads, substantially as described.

knitted fabric composed of two sets of filler Warp threads and a set ot' binder Warp threads, said filler warp threads eX- tending successively transversely and forwardly and each Eller warp thread, in its alternate Jforward extension, being sucsessively looped and reversely curved", ealch binder warp thread extending through and around the 11er-hs of the loops, and through tbe pockets of said re-.versely Curved pcrtions, of the filler warpfthreads, and in so extending forming loops binding together adjacent loops vand pockets formed by the filler Warp threads.

3. A knitted fabric efmiposed of longitudinal chains composed ot' a set of bindingv Warp threads and two sets of iller Warp threads, and transverse bars composed of said two set-s of iller Warp threads, each of said filler Warp threads being looped and reversely curved in the formation of said chain, and each of said binder warps extending,` along one chain only and in so eX- tending passing through the loops, and the pockets of the reversely curved portion, .of thef'izller Warp threads, and binding together the loops and pockets of the same, and also the loops and pockets of dil'lerent filler and Warp threads, substantially as described.

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 11th day of March, 1912.
