EDWARD n. ANGTER, or lammeren, MASSACHUSETTS.-

WINDOW CURTAIN. l

Application led January 31, 1922. Serial No. 532,971.

To all whom it may concern:

Be it known that I, EDWARD H. Alacran, a'citizen of the United States, and a resident of Framingham, county of Middlesex,

and State of Massachusetts, have invented an Improvement in `Wiiudow Curtains, of which the following description, in connec-v tion with the accom'panying drawings, isa specification, like characters on the drawings representing like parts. 3

This invention relates to window curtains or shades and the object of the invention is to provide a device of this character which,

- larly describe such a curtain in connection elastic body portion with the illustratin thereof in the accompanying drawings,'wherein:

Fig. 1 is an elevation of a portion of a window frame provided with a spring roller curtain illustrative of my invention; and V Fig. 2 is a fragmentary view of a modified form'of material applicable `foruse in such a curtain.

vBeferringto the drawings, I there show a sprin roller 3 of the usual or any preferred type aving the usual end pins 5 mounted in brackets 7 attached to the window casing '9. Secured to the roller 3, conveniently in the usual manner by a row of -tacks not. necessary to illustrate, is a flexible shade or curtain 11 which may consist of or embody in its construction one or more thicknesses of an irregularly gathered or craped paper and `which may be provided at the bottom with the usual stitl'ening bar 151for the atv tachment of a handle. Preferably kraft paper is emplo ed which 'is -strong and readily susceptib e to a' craping process. In the form of theinvention shown two thick'- nesses of paper are employed which are connected by a layer of. suitable lentous adhesive 13 such as mineral pitch.

The craped paper provides a flexible and for the curtain whichi rolls easily and is not liable to tear as would lain paper. Cloth which is employed fort window shades is quite stiff largely because 1t is sized or painted or otherwise treated to ll up` the interstices resulting from the weaving. A sheet of paper as distinguished from a woven fabric is a uniform felted body without interstices and does not require such stiifening to make it opaque or otherwise uniform in itsV light modifying qualities. Ordinary paper, however, is comparatively still and fragilel but when subjected to a 4'craping operation as described is soft and flexible and resistant to tearing as it will ive elastically under strain instead of startlng to tear;

A curtain presenting to the leyel a uniform surface of craped paper is really decorative resemblin in effect a popular' style of wall u paper an corresponding thereto iii-appearance when used .in windows of rooms so papered.`

Within 'the scope lof the invention the character of the shade may loevariously modifiedwhile preserving the essential char- .i

acteristics. in Vorder to rovide a more resistant body or .one having a desired ornamental apperance or a desired light modifying eect. Thus, colored papers or differently colored papers could be used or a paper having an appearance modified by the associated layer 13 and the paper may be more or less translucent or opaque as desired.

In any instance, however, the irregular crapings of the paper la er will increase the opacity if such effect is esired or w1l1 break up and modify the rays of light in the manner of ribs or irregularities on well known types of glass so that exhibition of shadows on the curtain will be avoided even althou h more or less light may be transmitted.

other wordsl a curtain may be provided intervening. layer of homogenous Amaterial such as the pitch 13 will also make for It will be readily understood that ythe material described 1s very inexpensive as compared with cloth. I will now 'set forth certain further advantages When cloth is em loyed its upper edge must be tacked to t eroller or barona elasticity of the cloth causes it to roll up askew. No great care is necessary when tacking one end of the described elastic paper to a spring roller because if the angle is wrong the paper will shape itself to a proper angle by pulling it down once or twice. In other words, if the tacking to the roller is such that the paper has a tendency to swing of to one side when pulled down, it is only necessary to pull it down straight until the usual bottom bar is parallel with the window sill and this causes one side or edge portion to stretch. After one or two such operations the paper will remain stretched in those portions thereof necessary to make the shade hang straight.

The craping of the paper renders it exceedingly flexible and I have practically demonstrated that it will roll up very evenly and smoothly and when wound up is not liable to slip sidewise so as to form, as cloth often does, a roll convex at one end and concave at the other end. Under certain circum- I' stances I may provide the curtain with longitudinal corrugations 17 as indicated in Fig. 2, causing it to hang stra-ight andv roll up evenly with the corrugations nesting 'in the turns of the roll. The long lines of the corrugations have a decorative effect and in certain applications are desirable'to neutralize the more or less transverse lines of the craping and will impart an effect of height and give a.G roomthe appearance of' being high ceiled and'airy.

When cloth is employed for window shades it must be either woven to the right widths for different windows or if cut it must be hemmed to avoid leaving raw edges. Paperas described, however, canlbe cut or trimmed directly to the right width to provide a curtain completely covering'the window without leaving any unsightly ed es.

A curtain or shade constructed as sown in Fig. 1 of two sheets of paper with interveningpitch is weather resisting and waterproof. For example, rain drivmg through the window and striking the outer layer of paper cannot penetrate through the inner layer of pitch 13 and the curtain as a whole is not weakened or disintegrated. 1

Having thus described in detail the particular embodiment 'of my invention illustrated by way of. example in the accompanying drawings, the principles exemplified thereby which I claim as new and desire to secure by Letters Patent I shall express in the following claims.

1. In a curtain for windows a support having depending therefrom a sheet of transversely craped paper.

2. A window curtain comprising a roller and a bottom bar havingextending between them a sheet of transversel craped paper.

3. A window shade embo ying in its construction as a flexible light modifying element a sheet of craped paper. i

4. A window shade embodying in its Lconstruction as a flexible light modifying element a duplex sheet lof craped paper having an intervening flexible coating layer.

.5. A curtain for windows embodying in its construction a sheet of expansible craped paper of suitable size having a cut or un-E finished edge. V j In testimonyv whereof, I have signed my name to this specification.

EDWARD H. ANGIER.
