T o all/whom it may concern;

Be itknown that I, JUNE' L. CHAPLINJHJ ycitizen of the United States,.residingfin theA city and county of Denver, and State of Colo.- rado, have invented certain new and useful Improvements in Flexible Joints for Double united by means of a flexible neat jointv4 which is both permanent and comfortable.

Briefly the invention comprises the uniting for each section of a plurality of strandsmade somewhat after the present practice, the threads projecting from the end of each section being overlapped and sewed together. One of the strands of each section is longer than the other, and this end is also wrapped into the joint and sewed. TheV joint is provided with a neat finish by' wrap- Y ping with a wisp of hair taken from either or both of the sections.

- In the drawings:

Figure 1 represents diagrammatically va single strand.

Fig. 2 shows the construction of each section after the strands thereof are twisted into shape, but before union of the sections. Fig. 3 shows the joint partially made. Fig. 4 represents the next stage; and Fig. 5 the last step. So-called fringe 10 of hair is woven upon three threads 12, as heretofore, to yproduce a strand 14. Each section of the double switch comprises at least one part which consists of three of said strands 14 twisted.

about a heavy cord 15 after the common practice, the twisted portion producing a core 16. One of the strands 14 is made longer than the other so that after said twisting operation there is an extension 114 having fringe 110, from which the threads 12 project. The twovsections at this stageV are shown inFig.l 2. Y

The next step consists in overlapping the cords 15 and threads 12 of the two shorter j strands, as indicated at 112, in Fig. 3, these drawn into the ythe wisps.

overlapping parts being sewed together as represented atv 20. 2 `The extending' portions 1140i the longer strands are then wrapped' V4about-the overlapped portions 112mm Sewed togetherto produce astrongbond as represented at 22 in Fig4l In' lcarrying ori-the last two steps, care is taken that the sewing and wrapping is not so vtight as `to make the'joint stiff. In other words, the joint, when properly fornied,"is soft-and fiexible,7bu`t durable and perma` nent.v Thev joint is then finished by'r selecting la wisp 25`of lo'ng'hair from either lor bothV of the sections, and wrapping'each wisp around the joint shown at 22 in Fig. 4 until the threads and sewingarel completely*H The tips o-f the wisps 25 hidden with hair. are then threaded into a large needle 26 and vbody of the sections, which gives a nice finish and permanently anchors The result is a having a neat, hair-wrapped iinish which is both comfortable and of excellent appear ance. Y

'I he number of parts, as above described, which may be joined into each section may be increased to two or three or four, as desired, and when this is done it permits the parts to be braided. In be taken from one side of the joint and folded back, onto` the other side so that the joint itself is completely covered and the appeaiance of a braid isgiven, which braid will be twice as long as the normal length of the hair. i,
