Specification of Letters Patent. Patented Jun@ 16, 1914 Application filed December 18, 1912. Serial No. 737,446.

To all 'whom it may concern Be it known that I, GEORGE F. EARNSHAW, a citizen of the/United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Twistless Tapes, of which the following is a specification.-

This invention relates in general to fabrics and more particularlyto narrow fabrics commonly known as tapes.

'lapes are very desirable for securing infants shirts and other garments in position on the body of the wearer instead of using pins or buttons which are uncomfortable to the wearer and pins particularly are apt to injure the wearer incase they become unfastened, or in case suiiicient care is not eX crcised in inserting them.

The advantage of using tapes for this purpose instead of buttons and pins has long been recognized, but the principal objection to the use of tapes resides in the fact that after the garment is washed the ordinary tape will twist or curl up so that it cannot be readily tied.

My present invention aims tape which will not twist or the garment is washed.

My invention will be best understood by reference to the following description when considered in connection with the accompanying drawings throughout the various views of which like reference characters refer to similar parts( Referring to the drawings: Figure 1 is a plan view of a section of a tape embodying my invention; Fig. 2 is a fragmentary section, on an enlarged scale, of the tape shown in Fig. 1.

to produce a curl up when rllapes as employed prior to my invention have been woven of warp and weft threads both twisted in the same direction, wlth the result that when the tape 1s wet the twisting.

of threads will .be increased andthe tape will curl up. The tape 5 illustrated in Figs. l and 2 of the drawings comprises warp threads 6 twisted in one direction and weft threads 7 formed of a continuous thread twisted in the opposite direction. While 1n Fig. 2 I have shown the warp threads as 5o twisted in right-hand direction and the weft threads astwisted in left-hand direction, it will be obvious that the warps might be lefthand twisted threads and the wefts righthand twisted threads. In any event, the twist of the warp and weft threads lies in opposite directions so that when the twist is increased upon wetting of the fabric the tendency of the tape to twist in one direction by reason of the twisting of the warp threads will be resisted by the twisting of the weft threads in the opposite direction and the tape, therefore, remains fiat and in its original condition.

Any suitable material may be utilized for the warp and weft threads, but, ordinarily, cotton or linen is employed. The material of which the threads are composed, however, is of relative unimportance so long as a portion, at least, of one set of the warp and weft threads are twisted in a direction opposite to a portion, at least, of the other set of threads.

It is believed that my invention will be fully understood from the foregoing without further description, and it will be obvious that by utilizing oppositely twisted threads for the warp and weft threads, I have produced a tape which will not twist or curl and will remain in its original flat condition regardless of the number of times that the arment to which it is applied may be was ed.

I claim :-v v

A woven tape consisting of interwoven warp and weft, the warp comprising a series of threads twisted in one direction, and the weft comprising a continuous thread twisted in a direction opposite to the direction of twist of the warp threads.
