R. WEINBERG ELASTIC TAPE Aug. 8, 1950 l/vvs/vroR Robert Weinberg BMM A fiar/lays Patented ug. 8, `195() 'UNITED ES TATE'S @FF "ELASTIC Robert Weinberg, N ew :lilo-nig, N Application January 24, 19219, SerialNo.`72;S'3-1 .Li-claims. (cm-c4193) This invention relates toielastic A'tape insertion for garments and has for ,its `principal :object to provide a tape Lof vnovel construction for use as a .narrow-seam:connection between garment secltions and which iis substantially inelastic longitudinally of y'the seam while `havling maximum y"elasticity across fthe width thereof.

`'Another object 4:is Eto provide an elastic lace tape ihaving inelastic selvedge portions, a plu-- Irality of lcngitutlin'ally r extending elastic lthreads eachihaving va lsuccessionbof loops .formed Atherein and lying ina common plane `with said selvedge portions, and ilongitudinal-ly 'extending inelastic threads in the form of chain stitches interconnecting 'the -closed rends-'of the adjacent loops of the elastic threads with each other and the alternate loops of =-the outermost Velastic threads .with :the inelastic selvedge s portions of "the ztape.

It is a further object of the inventionto'fprovide elastic ytape insertion .as vabove -characterized which maybe inexpensively produced by means of a conventional lace makingY machine.

' lWith the above-and otherobjects in Lview, the invention rvcomprises the improved elastic ltape insertion; and thevconstructi'onfand arrangement of its several parts, as will hereinafter be more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings, wherein I have disclosed one practical embodiment of my invention, and in which similar reference characters designate corresponding parts throughout the several views.

Figure 1 is a fragmentary elevation on a greatly enlarged scale showing the parts of the tape in Widely separated relation for greater clarity and illustrating one application of the tape as a seam insert between spaced parts of a garment;

Figure 2 is a longitudinal sectional View taken substantially on the line 2-2 of Figure 1;

Figure 3 is an elevation similar to Figure l, looking at the reverse side of the garment sections; and

Figure 4 is a side elevation illustrating the use oi the improved elastic tape as a seam insert between the front and back inelastic sections of a ladys slip or similar article of apparel.

Referring more particularly to Figure 1 of the drawings, the improved elastic tape is provided with an inelastic selvedge extending longitudinally along each of its side edges. As herein shown, this selvedge may be formed from a multiple strand `inelastic thread l0 having a oontin nous succession of loops I2 formed therein which alternately extend in opposite :directions to :the closed :ends lil :and =li6 respectively -of;said 1loops. rEhe louter sloop Vends Aof .the :selvedge thread l0 #are interconnected :by Vinelastic :thread forming 'the :line :o'f chain stitches :18.

The ,loop :ends i6 'of the selvedge :threads lll :alongeaoh `side edge ofthe tape .are connected by .1a ila-ce l.work ypattern fo'f interconnected velastic and inelastic threads. sAsishown, .a plurality V.of flongitudinally extending .elastic 4threads v20 .are .each formed intoa continuous fsuccessionof loops 22 with ther closed ends.'2i4=.and 2.6 .of said'loops alternately tfproecting yin Aopposite directions in similar `.manner '.to the `loops l2 rdf 'the :selvedge `threads. 'llhe .elastic thread iloops .are .disposed in acommoneplanewith:each other and withthe loops i2 of :the selvedge threads, ithe closed ends Aofthe loops :in said :elastic threads :extending in voverlapping .relation 'with each ether and loops .of the puter :most elastic threads 20 .ex-tending hetween :the sspaced closed .lends .I6 of :loops Al2 of the inelastic selvedge Y.thread l0.

The loops 22 of the outer side elastic ,threads 2D are interconnected with the inelastic thread loops l2 of thesselvegegnortions fof ithe'ztape by lthe :longitudinally extending inelastic .threads 28 which are formed into chain stitches the loops of which extend around the contiguous portions of the thread loops l2 and 22. Similarly the inelastic threads 30 are knitted so as to form chain loops interconnecting the loops 22 of the elastic threads 20 with each other at the contiguous closed ends thereof.

As seen in Figures 1 and 3 of the drawings, the inelastic selvedge portions of the tape are secured to the hemmed edges of two pieces of

fabric

32 and 34, which may be pinked as shown at 36, by the longitudinal lines of stitches 38 which extend over and firmly secure the opposite side portions of the inelastic thread loops l2 to the fabric sections adjacent the line of inelastic thread chain loops I8 connecting the selvedge loops I2. In the lateral movement of the

fabric sections

32 and 34 away from each other under stress, such movement is elastically resisted by the transmission of strain through the inelastic selvedge threads lll of the tape and the

inelastic threads

28 and 30 to the loops 22 of the elastic threads 20 so that said loops will be elastically elongated across the width of the tape. The

inelastic threads

28 and 30 will however effectively prevent any substantial elastic or resilient yielding of the elastic threads 20 in response to strain applied to the tape longitudinally thereof.

In Figure 4 of the drawings I have shown the above described elastic lace tape in one practical application thereof as an elastic seam 44 between the front and back portions 40 and 42 of a ladys slip or similar undergarment. It will be noted that the tape is comparatively narrow and extends from the center of the arm holes to the extreme lower edge of the garment. Thus, under the body strains the tape insertion will elastically yield locally at various points along its length while maintaining a substantially constant relationship between the front and back sections of the garment vertically thereof. By the improved elastic lace construction of the tape, maximum elasticity is obtained across the Width thereof, obviating possible rupture of the seam, and insuring greater bodily comfort to the wearer. It will of course be understood that the number of elastic and inelastic threads in the tape may vary in accordance with the required width of the tape and the particular purpose for which it may be used.

From the above description and the accompanying drawing, it is thought that the construction of my improved elastic tape insertion and the several advantages thereof will beV clearly understood. It may be inexpensively fabricated by a c-onventional lace making machine. The elastic and inelastic threads may be of predetermined selected weights, and if desired, for ornamental contrast with the garment to which the tape insertion is applied, the threads may be of a suitable selected color.

The invention may be embodied in other specie forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein,

What is claimed and desired to be secured by United States Letters Patent is:

1. Elastic tape comprising inelastic selvedge portions, and connecting means between said selvedge portions elastically yieldable across the Width of the tape and substantially inelastic lengthwise thereof, said means including a plurality of longitudinally extending elastic threads between said selvedge portions each having a continuous succession of loops formed therein and disposed substantially in a common plane with each other and with said selvedge portions, and a plurality of inelastic longitudinally extending knitted threads respectively interconnecting the loops of adjacent elastic threads at their closed ends with each other.

2. Elastic tape as dened in claim 1 wherein said inelastic threads form a connected chain of thread loops.

3. Elastic tape as dened in claim 1 wherein each selvedge portion of the tape includes loops of inelastic threads and said connecting means comprises a longitudinally extending chain of inelastic thread loops.

4. An elastic tape comprising selvedge portions of inelastic threadreach comprising a longitudinally continuous succession of thread loops, transversely elastic connecting means between said selvedge portions comprising loops of elastic thread having closed ends disposed substantially within the open ends of said inelastic selvedge thread loops, and longitudinally extending inelastic knitted threads interconnecting said elasticV thread loops and inelastic selvedge thread loops at their closed ends with each other and rendering thetape substantially inelastic longitudinally thereof.
