7Claims.

The objects of this invention are: I

First, to provide a water-proof cord suitable for use in furniture manufacture or the like having a Cellophane covering.

Second, to produce such a cord having a smooth even surface that is water-proof and pleasing in appearance.

Third, to provide such a cord in which a paper core which may be of any desired color is used in connection with transparent water-proof Cellophane.

Fourth, to provide a method of manufacturing such a cord.

Fifth, to provide a cord made of tissue paper or other loose fibrous material having a Cellophane covering wrapped thereon.

Further objects and advantages pertaining to details and-economies of construction and operation will appear from the description to follow. Preferred embodiments of my invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a broken view partly in section showing a machine for carrying out my method and manufacturing my cord.

Fig. 2 is a perspective view partly in section of one type of cord without the Cellophane wrapping thereon.

Fig. 3 is an elevational view of the cord of Fig. 2 in process of manufacture. Fig. 4 is a perspective sectional view, of the completed cord shown in'Figs. 2 and 3.

Fig. 5 is a detail sectional view of the com pleted cord of Figs. 2 and 3 and 4.

Fig. 6 is a different form of cord. The parts will be identified by their numerals of reference which are the same in all the views. Fig. 1 shows a machine for carrying out my method and for manufacturing the cord shown in Figs. 2 and 5. A fibre cord I, which may be jute or 'the like, is supplied to reinforce the main core cord 2. Strips 3 of tissue paper are spun around the cord l by means of spinning apparatus 4 which comprises a revolving frame 5 supporting thereon supply rolls 6 for the strips of paper 3. I I have shown an apparatus in which two strips of tissue paper are wound around the cord I from two supply rolls. It will'be obvious to' those skilled in the art that a single strip of paper 3 could be'used. The use of tissue paper is to make a rather large,- soft cord. Other materials could be used if desired. It is possible to use a kraft paper or any other cord I color and the "Cellophane" can be water-proof forming material.

The strips 3 are wound around the cord 1 and are passed to a forming die I that compresses the cord into a core cord 2 having a smooth even surface thereon. The core'cord passes around a pulley 8 and is fed to a glue pot 9. The glue pot co mprises a container l0 having a bottom 'opening M in which is'a. rubber sponge having a hole therein to permit passage of the cord while actingas a stufilng box. An opening I? is provided at the top and a rubber sponge I l having a hole for passage of the cord is used to wipe-excess of the cement used from the core cord 2. The cement 'used in the glue pot is preferably water-proof cement such as can be obtained in the market for gluing Cellophane. The core cord 2 is advancedfto a spinner l5 comprising a revolving frame It, that may be driven in any suitable manner, which carries a rotatably mounted spool'l'l on which is a narrow Cellophane strip. v

Tension means 58 are provided to maintain .tension on this roll as it is spun about the core 2.

The frame it is rotated around the cord 2 to apply thereto the Cellophane strip l9 which is a comparatively narrow strip which may be from one-eighth to one-fourth of an inch in width, if not wider. This strip is spirally wound around the core 2 with its edges overlapping.

I have described a specific spinner, but it willbe well understood that any type of spinner can be used. In the glue pot I have described the use of a rubber sponge stufiing box. These have been found to be especially effective in practice as they leave just the right amount of cement on the core to permit the wrapping under tension of the Cellophane to squeeze enough cement out between the overlapping edges of the Cellophane strip. It will be understood that a cement of proper consistency might be used without any means for removing excess from the core 2. It will also be understood that the spinning apparatus 4 could be disposed vertically if it wasdesired to feed the cord 2 without having it pass around the pulley8.

The paper I suppliedcan be .of any desired or not as desired. When a colored cord is used, the colorless Cellophane" can be used. This type of Cellophane is much cheaper and consequently a colored cord is obtained at the lowest possible price. The surface is completely water-proof if the water-proof Cellophane is used, and is very pleasing in appearance.

In the cord shown in Figs. 2-5 the cord I forms a core to permit feeding of the cord and use thereof without the breaking apart of the paper. The resulting structure has a layer of glue 2!, a layer of Cellophane 22 and a layer of lacquer 23 thereon, as shown in Fig. 5, the glue being between the overlapping edges of the Cellophane strip. In Fig. 6, I show a different form of cord. There is no core cord l and the core 24 of this strip may be formed of one or more strips of paper hard twisted to form a firm hard paper core which. in manufacture, is passed through a forming die similar to die I to give its. smooth even surface. The Cellophane is then applied as above described for the cord in Figs. 2-5.

I have described the use of a narrow strip of Cellophane about one-eighth to one-fourth of an inch in width. This has been found to be very effective in producing a smooth even waterproof surface on the cord because the cement is forced out between the overlapping edges.

It will be understood that wider strips can be used to advantage without departing from the invention.

It will also be understood that the colorless Cellophane need not necessarily be used as a covering although that is preferable because of its cheapness.

It will be further understood that I have described the use of a paper core with the Cellophane spirally wrapped therearound. I do not wish to be limited to the use of paper. Any suitable core forming material could be used without departing from my invention.

The lacquer coat applied to the surface of the finished cord may be dispensed with if it is desired. The lacquer is of advantage in that it fills in any raised edges of the spirally wound Cellophane and tends to form a fillet over the edges so that the Cellophane will not be scuffed up under ordinary wear.

I have described my invention in the embodiments preferred by me and wish to claim the same broadly as well as specifically, as pointed out in the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letter Patent is:

l. A cord for furniture manufacture comprising a core of flexible hard-twisted smooth-surfaced paper cord and a. narrow strip of waterproof Cellophane spirally wound around said core and afiixed thereto with waterproof cement and having its edges overlapping and cemented together with said cement to form a smooth even waterproof surface.

2. A cord for furniture manufacture comprising a core of flexible hard-twisted smooth-surfaced paper cord and. a strip of waterproof Cellophane spirally wound around said core and afiixed thereto with waterproof cement and having its edges overlapping and cemented together with said cement to form a smooth even waterproof surface.

3. A cord for furniture manufacture comprising a core of tissue paper having a cord core therein and a narrow strip of waterproof Cellophane spirallywound around said core and affixed thereto with waterproof cement and having its edges overlapping and cemented together with said cement to form a smooth even retaining shell having a waterproof surface.

4. A cord for furniture manufacture comprising a core of tissue paper having a'cord core therein and a strip of waterproof Cellophane spirally wound around said core and affixed thereto with waterproof cement and having its edges overlapping and cemented together with said cement to form a smooth even retaining shell having a waterproof surface.

5. The method of producing a smooth surfaced waterproof cord comprising hard-twisting a strip of paper longitudinally to form a core, passing said core through a die to form a smooth even surface on said core, passing said core through a bath of waterproof cement, supplying a narrow strip'of waterproof Cellophane to said core before said cement has set, spirally winding said Cellophane strip on said core with the edges of said strip overlapping, and maintaining tension on said strip of Cellophane as it is wound, whereby said strip is cemented to said core and cement on said core is forced between the overlapping edges of said strip as it is wound, whereby a smooth waterproof surface is formed.

6. The method of producing a smooth surfaced Waterproof cord comprising providing a core having a smooth even. surface, passing said core through a bath of waterproof cement, supplying a strip of waterproof Cellophane to said core before said cement is set, spirally winding said Cellophane strip on said core with the edges of said strip overlapping, and maintaining tension 1 the strip is cemented on said core and some of the cement is forced between the overlapping edges of said Cellophane strip during winding whereby a smooth surface is formed.
