June 17 1930. GILLBEE 1,765,145 I WINDOW SHADE F led Nov. 24, 1928 Patented June 17, 1930 UNITED STATES PATENT orrica MANUEL T. GILLBEE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO A. M. COLLINS.

MANUFACTURING COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORA- TION OF PENNSYLVANIA WINDOW SHADE Application filed November 24, 1928. Serial No. 321,716.

My invention relates to certain improvements in window shade -fabrics Whichare ap lied to spring-rollers.

no object of my invention is to insure the proper alignment of the fabric with the roller when the fabric is secured to the roller, so that the window shade will be parallel with the sides of the window'frame.

A further object of the invention is to provide the fabric with means for securing said fabric to the shade roller without the use of tacks or other metallic fastenings.

These ob'ects' I attain in the following manner, re erence being had to the accompanying drawing, in which:

ig. 1 is a perspective view of a window shade roller, showing a longitudinal indicating mark with which the 'window shade is aligned;

Fig. 2 is a perspective view of the upper end of a window shade,showing a longitudinal line on the shade and. perforations through which the longitudinal line on the roller can be sighted; and

Fig. 3 is a face view of a portion of a window shade applied to a roller.

Referring to the drawing, 1' is a springroller, of any type, having trunnions 22, one at each end. In the ordinary roller, one so of these trunnions is attached to a spring and suitable ratchet mechanism is used.

w is a longitudinal line, extending parallel with the centre line of the roller, w1th which 'the shade must be aligned in order to roll perfectly straight. This line or marking, which may be made in any suitable manner, .extends from one end of the roller to the other. I The window shade 3' is made of any suit- 40 able fabric, the word fabric being used in its broadest sense to gover paper or woven fabric, and in order to attach the window shade to the roller, a securing strip 4 is used. The securing strip 4 is of woven fabric and has an adhesive coating 5 on the back thereof, as shown in Fig. 2, which figure illustrates a portion of the securing strip turned up. The adhesive coating is moistened and applied to one end of the window shade as shown, and the window shade is sold With the securing strip attached thereto. i

In order that the window shade 3 may be properly secured to the window shade roll-- er 1, a longitudinal line a is printed on the face of the securing strip in any suitable manner, and at intervals the securing strip is perforated, the perforations I) being made in the centre, so that the line a will pass directly through the centre of the perforations, as shown in Fig. 2.

To apply the window shade to the roller, the back of the securing strip is moistened and the strip is laid upon the roller With the lines a and a: in alignment.

In order to allow the person applying the shade to the roller to readily see if the two lines are in perfect alignment, the line :2 on the roller will be visible through the perforations b in the securing strip, as clearly illustrated in Fig. 3. When the two lines are in exact alignment, then the moist portion of the securing strip is pressed down upon the roller until the adhesive material attaches the strip and its shade to the roller, after which the shade roller can be mounted in its brackets on the window frame, and if the I brackets are in proper alignment, then the window shade Will be parallel with the sides of the window frame.

In some instances, the end of the fabric maybe provided with adhesive inaterial and the fabric near one edge may be perforated and lined, dispensing with the securing strip.

I claim 1. The combination of a window shade roller having a longitudinal line extending parallel with the center line of said roller and a window shade having a series of perforations in its upper edge of such size that the longitudinal line of the said roller can be seen throu h the perforations of the window shade and showing the proper alignment of the window shade with the roller when 7 the shade is secured to said roller.

2. The combination of a window shade roller having a longitudinal line extending parallel with the center line of the roller and a window shade having a securin strip attached thereto, said securing strip aving m a series of perforations arranged on a line at right angles with the sides of the window shade so that when the window shade is applied to the roller, the longitudinal line of the window shade will be exposed through 15 the perforations in mounting the shade on the roller. Y

3. The combination of a window shade roller having a longitudinal line extending parallel wtih the center line of said roller and 20 a windowshade having a line at its upper edge at right angles to the side of the window shade and a series of perforations in said window shade, said line of the window shade I extending through the perforations so that I g when the shade is applied to the roller, the

line on the window shade can be brought into alignment with the line on the roller.
