9 Claims.

This invention relates to cellulosic cord produced primarily from such material as is commonly known as Cellophane; and the object of the invention is to economize on the construction of a cord or strand of this type while at the same time producing a finished product having greater luster or clearer color value thanhas been experienced with the production of devices of this kind, in accordance with methods heretofore known; a further object being to provide a strand of the class described consisting of a cord upon which is twisted a plain colorless strip of Cellophane, and around which one or more strips of colored Cellophane are spirally wrapped and partially twisted in the production of the resulting cord or strand producing a single or multi-color efiect on the resulting cord or strand; a still further object being to provide means for interlocking one edge of the outer strip with one edge of the inner twisted strip to more securely retain the strips one upon the other and to prevent unraveling thereof; and with these and other objects in view the invention consists in an article of manufacture of the class and for the purpose specified, which is simple in construction and efficient in use and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a detail view of a part of a strand made according to my inv tion and indicating the method of forming the same.

Fig. 2 is a view similar to Fig. 1 showing another form of construction.

Fig. 3 is a view similar to Figs..1 and 2 show-' ing another modification.

Fig. 4 is another view similar to Fig. 1 showing another modification; and,

Fig. 5 is a section substantially on the line 5-5 of Fig. 4.

In Fig. 1 of the drawing, I have shown one method of constructing a cord or strand according to my invention and, in this figure, I represents a core which may be composed of a thread, cord or other thin strand, which is preferably composed of rayon, and'this core is also preferably saturated with any suitable material which will maintain the resulting cord soft and pliable for a relatively long period of time.

One method of treating the core is by passing the same through a tank containing water and glycerine. At II is shown a fairly wide strip of plain or translucent cellulosic material, such as Cellophane, which is twisted about the core III to form an inner filler portion IIa;- at I2 is shown an outer or finishing strip which is spirally wrapped or wound around the filler II a it; the operation of twisting the filler upon the core III. The strip I2 isnarrower than the strip II or, in other words, is of sufiicient width to fully cover the filler Ila to produce on a resulting cord or strand I3 acolor governed by the color of the strip I2, which is red in the construction shown. In this connection. it will be understood however that this strip may be of any desired color, or may be of a combination of colors. If the same should be produced in this manner, the filter I la will be clear or colorless producing, when twisted, a silvery appearance upon a white core I0, and will produce in the resulting cord I3 a very high luster and clear color value of the color of the strip I2, that is to say, an outstanding sheen will prevail which is largely due to the silvery color value of the filler IIa formed from the transparent strip II.

In Fig. 2 of the drawing, the core III and strip II will be the same as that shown in Fig. 1 in the production of the filler Na, and substituted for the strip I2 are two narrow strips I2a and I4, the strip I2a being red, whereas the strip I4 is blue. In this construction, the resulting cord or strand I3a will have red and blue spirally arranged strips I5 and I6 thereon. In this connection, it will be understood that other com-. binations of colored stripsmay be employed depending entirely upon the effect to be produced, for example, red and green; black and orange, etc.

In Fig. 3 of the drawing, I have shown at III, II and Ma the core and. filler produced as in Fig. 1, and two narrow strips I Zaand I 4 simI- lar to strips I2a and I4 ofv Fig. 2, except that the latter strips may be a trifle narrower. than the strips shown in Fig. 2 and, in this construction, the resulting cords or strands shown in Fig. 3, by virtue of spirally wrapping the strips I2a and Il thereof will produce three stripings -on the I resulting cord I3b, for example, a red strip I 5a, a white strip I1 and a blue strip I6a to produce a red, white and blue cord, the silvery filler a 0 producing the so-called white appearance in the strip I'I between the red and blue strips. Here again, it will be understood that other color values may be employed than those specified, and with this construction it is also possible to use for the filler strip Ila, a colored strip instead of a transparent strip.

At this time, it is well to point out, however, that the purpose of utilizing the transparent'flller strip I la is not only to produce the increased luster and clear color value in the resulting cord but eflects a material saving in the construction of the product. This will be understood when it is realized that, as a rule, cords -of the type under consideration are made from, what is known as trimmings or end runs in the production of Cellophane sheets and, 'due to the fact that more transparent trimmings of this type are available than the colored trimmings, I have utilized for the main body of. the cord a filler composed of this transparent material and have utilized a small quantity of the colored material to give the desired color to the resulting cord.

It will also be understood that the strips I2, I21: and it are not simply spirally wrapped upon the filler but are also twisted to a slight extent which aids in supporting the strips in position.

In Figs. 4 and 5 of the drawing, I have shown a slight modification of the construction shown in Fig. 1 and, in this figure, Ill represents a core similar to the core l0 and II a strip similar to the strip II but, in this construction, the outer or cover strip I8 has one edge i8a thereof flanged over one edge of the strip ll so as to interlock the strip l8 with the strip H and, in this construction, a more secure binding is established between the strips II and [8, which will prevent the unravelling of the strip II. The resulting cord and strand I9 will have darker stripings 20 appearing thereon, where the flanged portion I80. prevails by virtue of the doubling of the material I8 upon itself, but the general color of the strip will be the same throughout but a more striped appearance will prevail, as is indicated in the shaded section at 20, in Fig. 4 of the drawing.

With the construction shown in Figs. 4 and 5 a greater twist will prevail in the strip l8 than in the construction shown in the other figures.

In addition to the advantages heretofore expressed, it will also'be understood that a cord or strand made in accordance with the structure herein described and, as shown in Figs. 1 to 5 inclusive, you will have greater strength than other cords of this type made from a single strip arranged upon a core, and still greater flexibility is provided in the resulting cord by virtue of the spiral arrangement of the outer strip or strips.

It will be understood that the outer strips or strands may be printed or otherwise characterized to produce various two-tone or multiple color effects on a resulting cord. It is also possible to utilize a multiplicity of thin ribbons simultaneously wound 'upon the filler, in accordance with the teachings in Figs. 2 or 3 of the drawing.

In order to secure the outer sharp or strips to the inner or filler strip, I may use a suitable adhesive'which may be applied to the filler prior to winding the outer strip or strips thereon, and this adhesive may be applied in spots or sections, if desired. 0n the other hand I may incorporate a suitable adhesive in the saturating solution applied to the core so that a part of the adhesive will penetrate, through the crevices of the filler and be exposed to the outer strip or strips for the purposes stated.-

Having fully described my invention. what I claim as new and desire to secure by Letters Patent, is:

l. A cord or strand of the class described comprising a core, a twisted filler of Cellophane" arranged on said core, and an outer covering strip of colored Cellophane" spirally arranged upon said twisted filler.
