ARTIFICIAL WHEAT-STRA'W BRAID.

Application filed February 23, 1924..` Serial No. 694,813.

This invention relates to imitation of vstraw braids, and consists in pasting on one or both sides ol white thin paper shavings of populus albo or any other grainless wood, which is dyed in any desired colour, coating the shaving thus dyed and lined, with nitrocellulose or any other cellulose ester solution, cutting it into tapes of any desired width, and plaiting them into braids. The object of this invention is to obtain goed material for summer hats, &c. which is cheap, does not easily 'tear olf, and closely resembles in its appearance to natural straw braids.

Hitherto shaving is commonly used as 1naterial for hats, but no attempt has yet been made to make it appear like straw. It receives no treatment other than bleaching, and consequently it retains all its woody appearance, and is glossless. It easily splits, and being devoid of waterproof property, easily gets soiled. f

Now, in this invention the film of nitrocellulose, or any other cellulose ester, gives to the shaving a horny look, and together with the white paper pasted on the reverse side, gives it gloss and appearance that cannot be easily distinguished from straw. This is due to the white paper pasted on the reverse side shining through the shaving and lilm of nitrocellulose, or the like.

Tapes in this invention are cut` into any desired width, and therefore there is no trouble ol" asserting them. They are less diiiicult in bleaching and do not lade by exposure to the sun. Especially, as they are tough, flexible and are not easily torn on, they are an ideal material for hats and bonnets. The following is a more lull description of my invention, reference being` had to the accompanying drawing. In the drawing Fig. l is a view of shaving pasted on paper and coated with solution of nitrocellulose or any other cellulose ester; and

Fig. 2 is a section thereof.

Fig. 3 is aview of the shaving eut into tapes, and

Fig. 4l is an example of such tapes plaited into a braid.

In the figures, (l) is a long continuous Japanese paper on one or both sides of which are pasted with a waterproof paste shavings oit populus albo or any other suitable wood, either bleached or unbleached, and dyed with a dye, ,or pigment, into light yellow colour so that they present an appearance resembling to the straw. Shay ings thus pasted are then kcoated with nitrocellulose, dissolved in a solution of camphor in alcohol, rthus forming a transparent, smooth and kglossy surface as shown at (3). This is cut into tapes (Ll), which are plaited into a braid as shown in Fig.

ln this invention, if the shaving is pasted only on one side of paper, the tapes will have an appearance of straw split, the paper representing the white inner layer, and'ii it is pasted on bothsides, the tapes lool; like straw flattened without splitting.

I claim:

l. As an article oi manufacture, artificial straw comprising tapes cut from material composed of a thin white paper and thin wood shavings pasted on the paper parallel with the length of the tape, and coated with a solution of a cellulose ester.

2. As an article of manufacture, artificial straw comprising tapes cut from material composed of thin white paper and thin wood shavings, pasted on both sides of the paper, and coated with a transparent varnish.

As an article of inanuilacture, artilicial straw comprising tapes cut from nmterial composed of thin paper and thin wood shavings of grainlesswood previously coloured, pasted on the paper, and then coated with a solution ot cellulose ester.

In testimony whereof have signed my name to this specilicaton.
