TWISTED Nnr FABRIC.

Specification of Letters Patent. Patented June 13, 1916.

Application filed February 18, 1915. Serial No. 8,988.

To all wkomc't may concern:

Be it known that 1, JOHN J. MCGINLEY,

a citizen of the United States, residing at ing operation so that it will be absolutely .chain beyond a very' small distance.

Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Twisted Net Fabric, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object ofmy invention is to provide a new and improved open work knitted fabric especially adapted for' use the manufacture of laundry bags anddyers? bags. Such bags are subjected to hard wear and are sometimes cut or torn atdifierent points. It. is important, therefore, that they should be so knitted or woven that if so torn or cut the damage will be localized.- This necessitates the weaving of the fabric insuch manner that the threads of which the fabric is woven shall beinterlo'cked at very frequent intervals in the knitting or weavimpossible to ravel any particular thread oAr fabric which submantially meets these requirements is set forth in a patent issued to Frank Clewley, May 11, 1915, No. 1,139,344.

This fabric is preferably knitted ona riblace machine in whichonly two guide bars, carrying two sets of needles, manipulating .two sets of thread, are rendered operative.

Two threads, one of one set and one of another set, are manipulated together as a pair and caused to interloop to form chains extending longitudinally or in the direction in which the fabric is knitted. Any given diverted laterally in theopposite direction and then interloopedto'form another series of loops ofthe firstchain, and so on. -Between the first and last named series of loops of the first chain is an intermediate series of loops formed by another pair of threads;

At the junction between two series of loops of the same chain, one of the threads of the pair forming one of said two series of loops 1s looped around oneof the threads ofthe pair forming the other of said two series of loops, thus tying together the two series of loops. Preferably, one thread of each pair,-

which may be called the locking-thread, always performs this looping function, wh le the other thread of the air, which may be called the locked thread, lsthe thread whlch is confined by the loop of the look ing thread of another pair; the locked thread at this point being itself formed into I a loop through which extends the locking thread of the last named pair in its transverse extension toward the adjacent chain.

The ob ect of the present invention, more specifically stated, is to improve the construction of the above described fabric, and

it comprises the combination, with the two sets of threads (which'may-be called main threads) interlaced as above described, of binder threadseach of which traverses only a single chain and extends through certain. of the main thread loops and is itself formed into loops which engage main thread loops.

In the preferred embodiment of the invention the binder thread extends through the loops of only one main thread of.each

of the two pairs of main threads with which it 1nterlaces-namely, the locking thread.

- The provision of a binder thread so interlaced with the main threads interlocks the threads with greater security and prevents even localv raveling. r

The invention will'be understood by reference to the accompanying drawings showing a preferred embodiment of myiinvention, in which Figure l is an enlarged face view ofthe fabric in which, however, the fabric is distorted to show the longitudinal rows ofloops extending on a straight line and to accentuate the open-work effect. Fig-2 is a face view showing more accurately the appearance of the fabric to-the eye. I w, y, 2, represent three adjacent longitudinally extending chains.

a, I), represent respectively the locking thread and locked thread of one pair of main threads.

a, 6, represent respectively the locking thread and locked thread of another pair of main threads.

It will be understood that the terms locking and locked are employed somewhat arbitrarily, the fact being that the connection between these two. threads is more in the nature of an interlocking con nection.

It will be observed that threads a and Z) are inter-looped to form a series of loops in the chain 13, thence extend transversely and form a series of'loops in the chain g'gand thence extend transversely to form another series of loops in the chain as; and soon.

- Threads a and b are interlooped to form a series of loops in the chain y, thence'extend transversely and form a series of loops in the chain 2, and thence extend, transversely and form another series of loops in the chain y; and so on.

The binder thread 0 of each chain is interlooped with the locking thread in the same manner that the locked thread is interlooped therewith. Thus in chain 4 the binder thread 0 is carried along with the locked thread I) through one series of loops, then (as thread 6 is diverted laterally) is carried along with the locked thread I). to form another series of loops in chain 3 then (as thread I) is-diverted laterally) is carried along with the locked thread 6 to form another series of loops in. chain y; and so on. Thus the binder thread, in the preferred embodiment of the invention, does not pass through the loops of the locked thread, but does pass through all the loops ofthe locking thread, and in addition thereto forms,

in conjunction with-a loop of the locking thread, a means of tying together adjacent series of loops in the same chain, as will be hereinafter more particularly described. Thus, the chain y is formed of a number of .series of loops formed by thread a and threads 6 and c, alternating with a number of series of loops formed by thread a and threads band 0. The other chains are similarly formed partly of loops formed by one pair ofinain threads and a binder thread and partly of loops formed by another pair of main threads and the same binder thread.

It will be observed, by reference (say) to the lower part of the section of chain 3 'veo . by thread a is interlooped with loops l ,ics

formed by threads 6 and c, which loops 4 in 1 turn extend around the neck of a fifth loop tion being established by both a locking thread and a binder thread. This description will suffice for an understanding of the entire fabric.

After the fabric is knitted the fabric tends to assume the form shown in Fig. 2;

that is, the tying in loops of threads a, a, etc., tend to draw out and elongate in a lateral direction owing to the pull between each series of loopsin one chain and the two series of loops formed by the same pair of mainthreads in an adjacent chain. This produces irregular but similarly shaped rows of figures, the figures of each row being .alternately staggered to the right and left.

Having nowfully described my invention,'w hat I claim and desire to protect by Letters Patent is: 1

1. A knitted fabric composed of a number of longitudinally extending chains, each of which comprises four main threads and a binder thread, one pair of main threads forming alternate series of loops of the chain'and integrally. united with another chain, another pair of main threads form ing the remaining alternate series of loops of the chain and integrally united with an other chain, While the fifth or binder thread extends continuously along the chain, and extends through the loops of one main thread of each pair in a manner similar to the extension through said loops of the main "thread of each pair.

2. A knitted fabric composed of a number of longitudinally extending chains each of which'is composed of threads forming other I cent series of main thread loops being inter locked and the binder thread extending with one main thread of each pair through loops of the other main thread of each r 3.
