ROLL SHADE Filed Nov. 5, 1932 Patented F eb. 27, 1934 UNITED STATES PATENT OFFICE ROLL SHADE Application November 5, 1932. Serial No. 641,432

1 Claim.

This invention relates to improvements in roll shades, and a principal object of the invention is to provide novel and improved means for attaching the shade to its roller.

Another object of the invention is to provide, as a new article of manufacture, a shade provided with means for attaching the shade to its roller, said attaching means being such as to facilitate the securing operation and to insure that the shade shall be properly positioned on the roller.

A still further object of the invention is to provide a roll shade of the stated character incorporating means for securing the shade to its roller, wherein said securing means also functions as. a supporting form for the shade, preventing creasing or .folding of the shade material and insuring delivery of the shade to the consumer in good condition.

In the attached drawing:

Figure 1 is a View in perspective of a standard type of shade roller;

Fig. 2 is a view in perspective of a shade made in accordance with my invention, and

Fig. 3 shows the shade and roller in assembly.

With reference to the drawing, I have shown in Fig. 1 a Window shade roller of Well known type. Customarily the shade is attached at one end to the roller by means of a series of tacks. In attaching the shade to its roller, it is essential, in order that the shade shall track properly upon the roller, that the normally parallel side edges of the shade shall occupy planes respectively at right angles to the axis of the roller. Considerable care must be taken in attaching the shade, and heretofore the operation has been a relatively diiicult one usually requiring an expenditure of considerable time.

I have devised means for materially facilitating the operation of attaching a shade of this type to its roller and for insuring that when attaohed the shade shall track true. My device also functions as a material aid to maintaining the shade in good condition during the period between manufacture and sale to the consumer.

In accordance with my invention and with reference to Fig. 2, I provide at that end of the shade to which the roller is to be attached a cylinder 3, said cylinder being preferably of a rigid or semi-rigid material and one capable of resisting torsional strains. For this purpose, I have found cardboard to be well suited, and cylinders of this material of the required physical characteristics are inexpensive and readily obtainable. Preferably the shade 2 is attached to the cylinder 3 by means of a suitable adhesive, al- 65 though any other means may be employed that may be found desirable. In attaching the shade to the cylinder, care is taken that the parallel side edges 4 of the shade shall occupy planes at right angles to the axis of the cylinder. Where the end-edge 5 of the shade which attaches to the roller is perpendicular to both the side edges 4, the desired condition may be obtained by laying the said end-edge along a line on the periphery of the roller which parallels the axis of the latter. The cylinder 3 has an internal diameter corresponding closely to the diameter of the roller 1, so that the roller may be slipped into the tube with a comparatively neat lit. With the roller inserted in the tube, as shown in Fig. 3, the cylinder may be immobilized with respect to the roller by means, for example, by one or more thumb tacks 6, which completes the assembly operation. Since the shade is true with the cylinder 3, and since the cylinder neatly ts upon 35 the roller 1, assurance is had that the shade shall also be true with respect to the roller.

A desirable and incidental feature of my invention resides in the fact that the cylinder 3 constitutes a form for the shade 2 upon which 90 the latter may be rolled. Possible damage to the shade by reason of creasing or folding of the material during the period between manufacture and sale to the consumer in thus largely avoided.

I claim:

As a new article of manufacture, a shade adapted for attachment to a roller and having at one end a substantially rigid cylinder of a size adapted to neatly embrace the roller.
