Application February 10, 1933, Serial No. 656,188

1 Claim.

The objects of my invention are:

First, to produce a Cellophane covered paper cored furniture cord.

Second, to provide such a cord that is water proof, of pleasing appearance, non-fading and inexpensive to produce.

Third, to produce such a cord that is especially adapted for weaving in imitation rush furniture and the like.

Fourth, to provide a method for making such a cord.

Fifth, to provide an article of furniture that is pleasing in appearance, non-fading, and which may be cheaply and easily finished with the elimination of several manufacturing steps.

Further objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. A preferred embodiment of my invention is illustrated in the accompanying drawings, in which: I

Fig. l is a plan view of an imitation rush chair seat made from my improved cord.

Fig. 2 is a perspective view of the twisted paper core used in my cord.

Fig. 3 is a perspective view of the core in process of being wrapped.

Fig. 4 is a sectional view of the finished cord.

Fig. 5 is a detail view of the weaving of the cord into the chair seat shown in Fig. 1.

Fig. 6 is a view showing the method of manufacturing the cord.

Fig. 7 is a detail perspective sectional view of a portion of the finished cord.

The parts will be identified by their numerals of reference which are the same in all the views.

My cord comprises a paper core covered with a Cellophane wrapper. The core I is made by loosely twisting a strip of paper. In making the core I have found that it is desirable to use a strip of fifty pound basis paper out in strips three and five-sixteenths inches wide.

Referring to Fig. 6, which shows the method of making my cord, the strip of paper 2 is fed from a roll 3 through a forming die 4 for twisting by a throstle 5 or any conventional twisting or spinning machine. The die 4 is of the funnelshaped type which folds the paper on itself longitudinally before the twisting. operation. The

throstle shown has drawing rolls 6 mounted on a revolving frame 'I and is provided with a roll 8 on which the finished cord 9 is wound. The throstle frame rotates to give a twist to the cord while the drawing rolls 6 are'advancing the cord through the forming die I.

The strip 2 is given a loose twist to produce a twisted cord having about seven turns to the foot. This cord is compressible to about one-half its size when woven and has a creased, irregular surface as is shown in Figs. 4 and 7. 5

In Fig. 6 I show the machine as a unit for making the cord, although the cord could be twisted on a separate machine and the Cellophane wrap could be applied in a different operation. In Fig. 6 I show a roll ID from which a water- 10 proof Cellophane strip I I is fed to the core I. The strip is about three-fourths of an inch wide and its core contacting face It passes over a glue pot I3 having a roller I4 which supplies a waterproof glue adapted for use with Cellophane to 15 the strip. The core I is rotated by the throstle 5 and advanced along its longitudinal axis so as to wrap the Cellophane strip I I around the core I in a spiral, which is accomplished because the Cellophane II is fed to the core diagonally. 20 The twisting and advancing of the core feeds the Cellophane strip II and the Cellophane conforms to the irregularities of the surface of the cord, as is shown in Fig. '7, and is cemented thereto. 25

The resulting structure is a paper core I with a spirally wound Cellophane strip I I having its edges I5 and I6 overlapping. The Cellophane is cemented to the core I by means of a film of glue I! which is shown in Fig. '7. As illustrated 30 there, the layer of glue appears to be very thick. This is done only for the purpose of illustration. The overlapping edges I5 and I6 are held together by the layer I8 of glue.

The core I may be made of any colored paper 35 and may be of variegated color to imitate rush, as is pointed out in my co-pending application Serial No. 538,073, filed May 18, 1931.

In using my cored cord with the Cellophane" wrapper, I can use the transparent "Ce1lophane 4 which is cheaper than colored Cellophane and can color the cord. I also use less Cellophane, which is a saving, at the same time givinga cord having the appearance of being solid "Cellophane. The cord itself is compressible to half 46 its size, which would not be feasible with solid Cellophane, and makes it especially adapted for use in imitation rush woven chair seats, such as the one shown in Fig. l.

As shown in Fig. 5, the cords 9 are compressed 50 at the point I9 to permit the weaving while leaving the cords 9 at the places other than at I9 in close proximity to one another. The chair seat shown in Fig. 1 comprises a frame 20 having comer pieces 2| of usual design.

woven, which leads to a considerable saving on floor space.

In the chair seat the cords 9 are wovenaround the frame in the usual manner, leaving the corner pieces 2| exposed. Lacquer is applied and-the corner pieces do not have to here-finished because of glue size thereon. The cords stand out individually and the spaces between them are not filled with glue size as is the case in'ordiriary woven chair construction wherein a glue size has to be applied. a

The finished cord is covered with a waterproof air-tight Cellophane wrapper and moisture will not injure the cords. The Cellophane conforms to the surface of the cord, lending a pleasing appearance and not giving too artificial an appearance to imitation rush furniture made in this manner. The covering, being air-tight, eliminates oxidation of the coloring matter, which is an important consideration. The furniture thus made does not fade as does the ordinary type in which the coloring matter is exposed to oxidation.

Although I have described the use of a definite weight of paper and size of strip, it will be well understood by those skilled in the art that this is not the only size of paper that can be used. It will also be understood that although I have specified a certain looseness of twist, any loose twist can be used. P y

I have described my invention in the embodiment'preferred by me, but'wish to claim the same broadly as well as specifically, as pointed out in 10 the appended claim.

Having thus described my invention what I claim as'new and desire-to secure by Letters Patent is: i

As an article of manufacture, a chair seat made to imitatea rush bottom chair seat comprising a frame having side members and an open center, and a cord woven to form a seat thereon, said cord being looped around said side members and crossed upon itself and compressed to about ,halfits size at the points of crossing in the centralportion of saidseat frame, said cord comprising a loosely twisted paper core having an irregular creased surface, said cord being compressible to about half its size and having a waterproof Cellophane strip wrapped spirally thereon with its edges overlapping and cemented and conforming tothe irregularities of the surface of the core.
