rz olaims. (Cl. 156-10) This invention relates to window shades of the flexible type, which are commonly suspended from and rolled around a spring roller, and in particular to such a, shade in simulation of a li Venetian blind.

. Venetian blinds are used primarily for decorative purposes as they impart a pleasing appearance to windows equipped with them. Also a desirable feature in Venetian blinds is the provision for control and modulation of light passing through the slats thereof. Certain inherent disadvantages however, prevent their becoming universal of adoption. Such blinds are costly of manufacture, are bulky when in use, are dust col- 15 lectors, and are diificult of cleansing by the average housekeeper.

The conventional window shade while possessing none of the disadvantages of'the Venetian blind has little or no decorative value and its 20 drab appearance is usually out of harmony with any plan of interior decoration or color scheme and thus soon becomes tiresome of appearance. Also such a shade has no provision for control and modulation of light, other than to expose 25 the window by rolling up the shade.

I propose to provide a window shade of the conventional type .having printed or painted or otherwise delineated thereon, bands of color in simulation of the slats and tapes of a Venetian 80 blind, and thereby combine the decorative and light modulation features'of such a blind with i the advantages of the conventional rolling window shade. but having the disadvantages of neither.

85 Ialso propose to provide in such a window chase 'any desired length or width of the printed or painted material and attach it to the present A li shade roller, thus deriving the advantages of a I window shade simulating a Venetian blind at small cost. v

It is therefore a primary object of my invention to provide a conventional window shade 50 having bands of color delineated thereon in sim- I ulatlon of the slats and tapes of a Venetian blind.

" Another object of my invention is to provide 1 in a conventional window shade a multicolor I simulation of a Venetian blind.

Another object of my invention is to provide a conventional window shade of one color, having printed, painted or otherwise delineated thereover bands of color of different colors in simulation of the slats and tapes of a Venetian blind.

Another object of my invention is to provide a conventional window shade having front and back surfaces printed, painted or otherwise proc--v essed in the same or diiferent color combinations.

Another object .of my invention is'to provide in a conventional window shade removable and replaceable tapes of appearance simulating the tapes of a Venetian blind.

reflected lamp light within a room against the inner side thereof or to give the interior effect of sunlight against the outer side thereof.

Another object of my invention isto provide a conventional window shade having bands of color printed, painted or otherwise delineated thereon in lights and shadows in simulation of the slats and tapes of a Venetian blind, the shadows thereof reflectingoutside daylight and inside lamp light and the lights thereof permitting the passage through the shade of controlled 80 daylight or lamp light.

Another object of my invention is to provide equalizing means for a window shade having tapes mounted thereon, said equalizing means compensating for the additional thickness given as to the shade at the point of attachment of said tapes.

With these and other objects in view which will readily appear as the nature of the invention is better understood, the same consists in 40 the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been illustrated a' simple and preferred form of the invention, it being understood, however, that no limitation is necessarily made to the precise structual details therein shown but that alters-,- tions and modifications within the scope of the appended claims may be resorted to when desired.

In the drawings: r A Fig. 1 is afront view in elevation of a conventional window shade having printed, painted or otherwise delineated thereon bandsof color printed, painted or otherwise delineated on the shade material to indicate a downward and outward slant thereto and the reflection therefrom of lamp light in a room;

Fig. 2 is a front view in elevation, similar to m Fig. 1 but showing the printed, painted or otherwise processed bands of color of the window shade slanted upwardly and outwardly and giving the effect of sunlight against the outside of the shade. Also shown in Fig. 2 are tapes adhesively. mounted on the shade; and

Fig. 3 is an enlarged fragmentary view showing a conventional shade roller and the manner of attaching the window shade to same. Also shown in Fig. 3 is the equalizing means and manner of attachment thereof when tapes are adhesively attached to the window shade.

Referring to the drawings in detail wherein similar reference characters designate corresponding parts throughout the several views; 5 is a window frame and casing, to the inner walls of which are attached the well known spring roller brackets 6 and 1. Supported by and operating in brackets 6 and I, is the usual window shade spring roller 8, to which is attached in the well known manner as by tacks 9, my improved window shade l0 having printed, painted or otherwise delineated thereon bands of color II,

and bands of color l2 and I3, in simulation of the slats and tapes of a Venetian blind. Window 'shade l0, isequipped in the usual manner with shade stick l4, and pull cord I5. I6 and I1 are adhesive tapes of material simulating the fabric of the tapes of a Venetian blind, and which if desired, may be mounted directly over imitation tapes l2 and I3 respectively when it is desired to change the appearance in color or texture thereof. While any tape and adhesive or adhesive tape may be used, I have found the well known Scotch tape (a trade name) well suited for my purpose in that it is flexible, has excellent adhesive qualities and due to its non-drying character, may be removed at any time for replacement by new tape of the sameor other color and. texture. Obviously when tapes l6 and I! are mounted on the shade Ill, an appreciable additional thickness is given to the shade at the points .of mounting. This is of no moment in heavy shade materials, but in the lighter weights of shade materials a tendency to wave or wrinkle is observed when the shade I0 is rolled up on spring roller 8. To obviate this difllculty when tapes l6 and I! are mounted on the shade I 0, I provide equalizing filler pieces I 8, l9 and of felt or other suitable material which are disposed outwardly of and between tapes l6 and I1, and are attached under shade I0, and to spring roller 8, by tacks 9. When shadelll is rolled up on spring roller 8, the filler pieces l8, l9 and 20 are rolled between the first laps of the shade Ill and are hidden from view. It is obvious that spaces 2| and 22 betweenfiller pieces l8 and i9, and I9 and 20 provide for the additional thickness given by tapes IS and IT to shade l0.

Particular reference is now made to shade III which may be of paper, or oil opaque, Holland or washable shade cloth or other suitable material. 'As before pointed out, the bands of color H and bands of color l2 and I3 are printed. painted or otherwise delineated on shade It. For

. purposes of brevity in description I now propose and showing the conventional to confine myself to printing, it being imderstood however, that printing shall broadly include other methods of obtaining an equivalent result.

Window shades of translucent or opaque materials may be obtained in many colors. I find, that using the shade material color as a foundation color, and printing bands on the shade material in color of deeper tone than the foundation color, and having shadows at the top of the bands of color, will give the effect of the slats of a Venetian blind reflecting lamp light within a room, and that by printing the bands in color of deeper tone than the foundation color, and having lights at the top of the bands, gives the effect of sunlight against the slats on the outside of a Venetian blind. I also find that leaving unprinted the delineations indicated as l2 and I3, gives the effect in bands of foundation color of tapes which lend to the simulation of a Venetian blind. I also find that casting the lights and shadows and tones thereof to indicate a downward slant as shown in Fig. 1 or an upward slant as shown in Fig. 2 of the bands of color, greatly adds to the simulation of the lights and shadows of a Venetian blind.

The foregoing is indicative of the results that may be obtained through single color printing. ,By the use of two color or multicolor printing any desired shading or combination of color tones is available. For illustration bands l2 and I3 may be made a different color than that of either the foundation color or bands of color H. Also it is obvious that by use of two color or multicolor printing, the lights and shadows and efiects maybe enhanced by the super imposition of color over color. It is also pointed out that my improved shade may be printed to simulate a Venetian blind on either or both sides of the shade, thus giving the choice of an exterior and interior effect of a Venetian blind or a plain exterior and an interior of Also my improved shade may be printed on duplex cloth (viz': difierent foundation colors on each side) which makes possible having shades with interiors simulating Venetian blinds of diflerent colors to harmonize with the color schemes of different rooms, and presenting an exterior of uniform color, either printed in simulation of a Venetian blind, or left in natural color.

In addition to the effects that are obtained as before set forth, I find that a translucent material gives a striking optical effect when bands of color are printed thereon in simulation of the slats and tapes of a Venetian blind. The proper selection of colors, and the printing of lights and shadows in various tones on the shade material, allows outside daylight or inside lamp light against my improved shade, to reflect from the shadows thereof, or pass through the lights thereof, and such modulation of light gives the much desired effect of light passing the slightly tilted edges of the slats of a Venetian blind. This is not a mere printing operation, but a definite control of light reflection and penetration, accomplished through the imposition of controlled colors in controlled places, and by which the intensity of the light is controlled to yield effects inlight modulation substantially the same as those obtained through use of a Venetian blind.

As before pointed out adhesive tapes l6 and I1 may be mounted over printed delineated tapes l2 and I3 or over the foundation color if l2 and it are not printed on the shade, in order to pro- 7 vide color or of tapes to harmonize with any decorative plan or color scheme. 1

It will appear from the foregoing description that I have provided a window shade of the conventional flexible rolling type printed in simulation of a Venetian blind, and simulating the slats and tapes thereof, and the lights and shadows thereof, and providing for the control and modulation of light reflecting from or passing through the bands of color thereon and said shade.

It will also appear that I have provided in such a shade a printed opaque shade in simulation of a Venetian blind, which by color control and printed lights and shadows in various tones, provides reflection simulating outside daylight or inside lamp light-against a Venetian blind.

It will also appear that I have provided removable and replaceable tapes for adhesive mounting on such a'shade, in order to vary the color and texture thereof at will, and it will also appear that I have provided means for compensating for the additional thickness given to the shade at the points of mounting such tapes.

It will also appear that I have provided in such a shade a duplex cloth having different interior and exterior foundation colors which may be printed in simulation of a Venetian blind on the exterior thereof to conform with the interior thereof or which may be left plain on the exterior side thereof.

It will also'appear that I have provided in such a shade,,an interior in simulation of a Venetian blind in one color combination of lights and shadows, and an exterior of the same or a different color combination, or in plain foundation color.

It will also appear that I have provided in such a shade a simulation of a Venetian blind which, while avoiding the disadvantages in bulk,

cost and difficulty in cleansing of the Venetian and shadow effects, in simulation of the slats of a Venetian blind, said delineations forming obstructions of graduated effectiveness to the passage of light through said material.
