BRAID AND METHOD OF MAKING THE SAME.

Application filed February My invention is a braid particularly adapted for the manufacture of rugsand having each of its surfaces formed essentially by filler or warp strands which are wholly in visible from the opposite surface; theV filler strands of the two surfaces being preferably spaced by substantially unbent stuffer yarns or threads, and the whole bound together by interlaced binder threads passing from one surface to the other of the braid and forming patterns therein. Such a construction is not only economical of the expensive surface strands, but permits the formation of a rug having opposite surfaces each of which has a complete and finished appearance, and each of which surfaces may be made distinctly different from the other in color and/or in texture.

In the preferred practice of my invention, a braid is formed from a pair of sets of longi" tudin'al surface strands, one set of strands forming what may be arbitrarily called the top and the other set ofv strands forming what may be arbitrarily called the "bottom These terms are, however', merely relative and either surface may be regarded as the top and the other surface as the bottom. The top and bot-tom sets of strands are preferably spaced by a pair of sets of longitudinal stuffer threads similar in color to or harmo nizing with the surface strands to which they are respectively adjacent, and the longitudi nal strands and threads are bound together by several pairs of sets of binder threads. The sets of each pair of binder threads are preferably the same in color and texture and travel in opposite directions, and the threads of one pair preferably contrast in color with the threads of the other pair. The pairs of binder threads alternate with one another along each surface of the braid and prefera bly the sets of each pair pass under the edge strands of one set or top surface strands at different places along the braid, then over the inner strands of such set of surface strands, across and intertwine with one an other on the top to form an arrowhead shaped figure or pattern, then pass under the inner strands of the top surface set of strands, over the outer strands of the same surface set and across the side surfaces or edges of the braid, where the threads of the sets of contrasting pairs intertwine, thence over the edge strands of the opposite or bottom surface, under the inner strands of bottom surface, cross one anvother and interlace to form an arrowhead 13, 1926.

shaped figure on the bottom face, thence pass over the inner strands of the bottom surface, under the edge strands of the bottom surface, and around the thickness of the braid, interlacing across the edges with the contrast-ing threads coming from the opposite surface. The operation is then repeated. The braid so formed is sewed together with the side edge of one convolution juxtaposed to the side edge of the next convolution, so that the rug has two surfaces differing distinctly from one another, but each surface having therein patterns formed by the interlacing of the sets of binder threads.

In the accompanying drawing, Fig. 1 is a plan view of a. rug embodying my improvements with one end thereof foldedV over to show the opposite surface; Fig. 2 represents diagrammatically a cross sectional view of the braid from which the rug is formed taken on the section line 2-2 of Fig. 6; Fig. 3 illust-rates diagrammatieally a cross sectional view of the braid taken on the sect-ion line of Fig. 6; Fig. 4 is a diagrammatic perspective view of a braid section with portions removed for clearer illustration; Fig. 5 is `a diagrammatic view of the vbraid sur'- faces projected as a plane and Fig. 6 is a diagrammatic perspective view of a braid strip twisted to show the two wearing surfaces thereof.

As illustrated in the drawings, the rug is formed by securing together', as by sewing, convolution of a braid with the side edges thereof juxtaposed. One wearing surface of the braid comprises a plurality'of strands, preferably chenille, l, 1b, 1, l, and the other wearing surface of the braid comprises a. plurality of strands 2a, 2", 2c and 2d, preferably of chenille contrasting in color, or if desired in texture, with the strands 1211), 1c and 1d.

VThe surface chenille strands are spaced by sets of stuffer threads 3 and 4 suitably of cheap yarn,y the stuffer threads 3 ,harmonizing or conforming in vcolor with the chenille threads la, l", 1, l, and the stuffer threads i harmonizing or conforming in color with the chenille threads 2, 2b, 2c and 2, the stuffer threads are primarily designed to vform a core giving body to the braid and are not intended to be visible from the surface. I

The surface strands and stuffer thread are held against twisting or displacement by suitable means and while so held are bound together in a. braid by two pairs of sets of binder threads; onev pair consisting of the sets and "6 and "the dther' pair consisting of the sets 7 and 8. Y

The

sets

5 and 6 respectively pass under the edge strands 1a and 1d, and over the inner strands 1b and 1. The sets 5 and Gthen cross and intertWine or interlace ivith one another to form a figure or pattern 9. The set` 5 then passes under the strand 1C and Vover the strand 1d and the set 6 passes under the strand 1b and over the strand 1, This tends to draw the strands 1b and 1c together as indicated at in Fig. 6.

The

binder threads

5 and 6 then respectively pass downwardly over the opposite lateral edges of the braid and in about the plane'of the invisible stuffer threads 3 and 4 cross and intertwine with the respective binder threads 7 and8 coming up from the bottom Wearing surface formed by the che nille threads 2, 2b, 2", 2".

After crossing the threads S, the threads 5 pass over the edge strand 2, 'and under the inner strand 2c, While the threads (3, after crossing the threads 7 pass over the edge strand 2 and under the inner strand 2b. The sets of threads 5 and'G then cross and intertwine to form an arrowhead shaped figure or pattern 11 on the bottom of the braid similar to the figure 9 on top of the braid but having its point extending in theopposite direction. The threads 5 then pass over the inner strand 2b, under the edge strand 2, around the edge of thebrai-d, crossing the threads 8 and repeating.` The threads 6, after forming the pattern "11,pass`ove'r the inner strand 1c under the edge strand l, around the edge of the braid, crossing the threads 7 and repeati ing.

The sets of threads 7 and 8 follow courses similar to the courses of the

threads

5 and 6 and alternate therewith. Thepoints Where the threads 7 and 8 cross one another on one Y side of the braid are slightly staggered relativelyto the points Where the

threads

5 and 6 cross one another on the opposite side of the braid.

The respective binder threads 7 and 8 passV under the respective edge strands 1d and 1, over the inner strandslh and 1, cross and intertwine with one another to form the pat tern 12, pass under the inner strands 1c and 1b, over the edge strands 1d and 1, around the sides of the braid crossing and intertwining with the sets of

threads

5 and 6, then passing respectivelyover the edge strands 2d and 2, under the inner strands 2c and 2", crossing and intertwining to form the pattern 13, over the inner strands 2" and 2, under the outer strandsQ and 2d, around the sides of the braid, crossing and intertwining with the sets of

threads

6 and 5 and repeating. Y

The braid so formed is of substantially rectangular cross section. The longitudinal surface threads 121212122222? andi!d are but slightly bent and no portion thereof is Wasted Amade Whollydifferent in appearance and texture. Any desired number of ends may be used in the surface strands, binder, threads and stuifers. The stuffer threads backing the surface strands prevent any chance of the Vopposite surface strands showin through. The braid may have lits latera edges sewed orotherwise fastened together to forni :trug of any desired shape or site, but preferably the braid convolutions are wound together as shown in Fig. 1 to produce :a rug having a curved periphery. If desired braid sections of different colors may be united in one rug to form a pattern on each surface, such as the ring 14 or margin 15.
