This invention relates to paper window shades.

The general-idea of paper window shades has much to recommend it, in that they are cheap, can be frequently changed without a great expense, and lend themselves readily to an infinite variety of patterns and color schemes. Coloris becoming more and more in demand .throughout industry as well as throughout interior decoration, and the plain drab appearance of the conventionalA window shade is tendingto decrease its use very materially. There is, however, one very severe drawbackinherent in the idea .of paper window shades. Pa er is possessed of a grain. The paper as greater resistance to stresses applied in line with the grain than it has yto stresses applied transversely to the grain.. Therefore,l if the paper be applied to the roller with the grain parallel to the roller the shade has the very decided tendency to tear.- If, on the other hand the shade be applied to the roller with the grain transverse or at ri ht angles .to the roller, the paper hasa ten ency to curl, or`

retain the curvature imparted to it by the roller. p

The object of this invention is to provide a paper window shade adapted to be attached wat the top to a rollerfand'at the bottom to a stick, adapted to be of any color or to bear i. \an ornamental design, possessed of sufcient strength to vwithstand the strain to y which it is to bsubjected in use, yet characterized by flexibility s uicient to cause it to hang vertically from'the roller without curv.- ing,4 bending or curling. j her objects and furtheradvantageswill 'l be more fully set forth-in the accompanying drawings, in which; i

'I'he grain runs trans-v versely or at right angles with the roller. The tendency of the paper to curl is corrected by means of embossing or minute creasing applied tothe paper transversely to the grain, the effect of which is to break the grain to a degree suficient to cause it to hang vertically without tendency to curl.

As disclosed, an ornamental design has been applied to one side of the shade, the embossing or minute creasing not having been\v i sulicient to impart to the surface of the paper a roughness or lunevenness .inhibitory to the applying of the design to the shade byl pressroom methods. Since the pull upon the shade in use is parallel to the grain the shade does not have a tendency to tear at the edgesv and yet since the grain is broken or impaired by the tansverse embossing or minute creasing1 the shade-does not have a tendency to cur i Across the bottom of the shade is secured a strip of gum paper 3.

2. A new article of manufacture, comprising, a length of paper having at one end thereof a gummed strip adapting said length of paper to be secured to a Window shade roller, the grain of said length of paper running at right angles to said gummed strip and 4 embossing transverse to the grain of the pa- 'A grain sufficiently to destroy the tendency of 3.

A new article ot manufacture, comprising, a length of paper, one end of which is adapted to be secured to a Window shade roller, and minute creasing substantially parallel to the end adapted to be attached to the roller.
