" FLEXIBLE CABLE FOR, LAMPS.
, Specification of Letters Patent.
Patented Oct. 19, 1909.
Application filed September 12, 1908. Serial No. 452,708.
I insulating material, and it is theaim of my invention to increase the flexibility of this cable and to improve the protection aflorded by the beads.
Flexible beaded cables are generally used in connection with are lamps for connecting the movable parts of the same electrically in such manner that whenthe sides of the' cable come in contact with the different parts of the lamp, which is almost unavoidable, no short circuit or ground can be made. In order to afl'ord sufficient protection the beads on the cable must be of fair size and if these beads are all of uniform size, as has heretofdre been the case, and the cable is bent sharply, which is frequently necessary, there is exposed a considerable portion of the bare cable, which is liable to lead to short-circuits or grounding. The flexibility of the cable is also limited by the requisite size ofthe beads.
According to my invention, I arrange small and large beads alternately upon a cable, and thereby the danger of short-circuits is largely decreased, and in addition thereto, the cable is made more flexible.
My invention is illustrated in the accompanying drawings, in which Figure l is a longitudinal section of a piece-inf cable. made in accordance with my invention; and Fig. 2 is an elevation of such ,2, the edges of the adjacent beads do a cable shown bent, so as to illustrate the improved protection afforded by'the two sizes of beads.
Like numerals of reference parts.
Referring to the drawings, 1 represents a conductor usually provided with an insulating braiding, as indicated, and upon this conductor are strung beads of two sizes in alternation. The beads 2 in this case are all of the same size as heretofore used, but they are alternated with beads 4 of a smaller size. In consequence of this construction, when the cable is bent,as indicated in Fig.
indicate like come into contact, but the edges of the smaller beads come in contact with the end faces of the larger beads, and in this manner, owing. to the smaller diameter of the beads 4, the length of the conductor which is exposed, as indicated at 3, is considerably reduced and the opening .between the beads is also largely reduced, so that access to the small portion of exposed conductor by the hand is practically prevented and contact of metallic parts of the lamp with this exposed portion is practically impossible.
What I claim as new and desire to secure by Letters Patent of the United States, is,-
1. A flexible conductor provided with insulating beadsof alternately large and small diameter, loosely strung upon the conductor.
2. A flexible conductor provided with porcelain beads of alternately large and.small diameter strung upon the conductor.
In witness whereof, I have hereunto set my hand this tenth EMILE J. GUAY.
