asser MARY E. MURPHY, E DALLAS, TEXAS REVERSIBLE WINDOW sHADE AND SECURING MEANS Application filed June 17, 1929. Serial no 371,471.

This invention relates to new and useful improvements in window shades and has particular reference to a novel means of securing window shades to the conventional rollers to prevent their disengagement from the latter under strain.

Another object of the invention resides in the provision of a novel means of attach ing shades to rollers so that the shades be reversed and consequently renewed at their lower ends, which often become soiled and torn.

Still another object of the invention is manifestin the provision of a means, as

described, capable of saving considerable eX-' arelikely to be careless in drawing them' down, causing the shade to unwind from the roller and become detached therefrom.

Having thus setforth its novel objects and salient features of construction, a more 80 detailed description of the invention follows, taken in connection with the appended drawings in which Figure 1 is a perspective view showing the invention as applied to both the upper and 85 lower ends of a shade.

Figure 2 is a cross-section of a roller showing the way in which the shade is attached. Figure 3 is a modification of the securing means showing a clamp having teeth.

Figure 4 shows the preferred means of securing the shade to the roller.

Figure 5 is a modification of the securing means shown in Figure 4. Figure 6 is a plan View of securing means 15 shown in Figure 5. I Figure 7 is a perspective view of the clamp shown in Figure 3, and

Figure 8 is a fragmentary elevational view of the invention as applied to a roller, showing the preferred style of stitching the shade at'the bottom, maybe inserted.

and a type of wire staples used for securing the shade to the roller. I 1

' The ordinary method'of securing window shades to the rollers with tacks or clips is unsatisfactory, due to the fact that. wl1en'55 "the shade is completely unwound from the roller, a little strain might tear it loose, resulting in not only damaging the end'connected to the roller, but endangering 'the shade as a whole, since a wrinkle or a crease inmaterialsuch as used for window shades will break the texture and to show through. o Under the ordinary methods, it is not practical to reverse the ends of the window shades for the reason that only one end of the latter 7' is hemmed to form an enclosure for a stick,

allow the light 'which is universally used in window shades to maintain rigidity at the bottom.v The methodherein described provides a hem of" like dimensions on either end of the shade in which 'eitherthe roller, at the top, orthe stick Proceeding morein detail, reference'is again made to the drawings and primarily to the character 1 representing theshade, eitherrend of which is hemmed to define-a tube-like enclosure 2. Through the topmost of these enclosures 2, a conventional shade through the lowermost enclosure, as shown in Figure 1.

Particular reference is made to Figure 2 showing the relationship of the roller 3 to the enclosure 2 and one means of securing the folded'edge a of the shade to the-shade sur- 1 face. I This may be accomplished by stitching, as shown in Figures 1 and 8 at b, and'in Fig ure 3- at 0 or by gluing thesurfaces together As the enclosures 2 must be of suehdimensions as to allow the roller 3 to be freely ins'erted therein, a means mustbe provided to prevent the shade from slipping onthe roller, This may be accomplished by the use of small wire staples. 5, inserted into the roller buta preferred means of securing the shade to the roller is a clasp as exemplified in Figure4, which vcomprises a small strip of metal 6 of such shape as tobe applied to the roller by tacks or the like, at one end, the opposite end of which is sharpened to define a point 7 which can be pressed into the roller 3 through the shade 1 to prevent the latter from turning on the roller 3.

It is not intended, however, to limit the clasp 6 to the structure shown in Figure 4 and for that reason a modified type of clasp is shown in Figures 5 and 6. The metal caps 8 of the roller are constructed to define a tongue 9 having a point 10, similartothatof the clasp 6 which may be pressed into the roller as shown in Figure 5.

In order to prevent an excess of unsightly perforations in the enclosure 2, through Which the roller-3'operates, it is desirable'to-place .the clasps 6 and 9 immediately upon top of the roller when the shade is placed thereon. This will place the small perforations made by the points 7 and 10 of the clasps at the bottom of the'stick 4 in the lower enclosure 2 when-the shade has been reversed.

A further modification of a means for securing the shade 1 to the roller 3,;isshown in Figures 3 and 7 A springlike clamp 11 is provided, having triangular shaped portions out from the ends thereof and 'turned inwardly to define teeth 12 which maybe pressed into the roller 3'to holdthe shade secure to the latter.

lVhen it is desired to reverseithe'shadegthe clasp 6 or 9 canbe lifted in the manner shown :in Figures l and 8 and the shade slipped from the roller 8. The opposite end may be slipped onthe roller 3 and the clasps 6 'and9 maybe pressed down again.

Obviously, considerable modifications may be made in the construction shown and such modifications as are considered within the scope and meaning of the appended claims without departing from the spirit and intent of the appended claims.

lVhat isclaimed is: 1. In a reversible'window shade, thecom- 'bination ofa sheet of fabric having hems of equal size at either end, and a securingmeans including a clamp comprised of semi-cylln- -drical rings joined'together at theiropposite ends by integral strips disposed in parallel relationship, the said rings having substantially triangular projections struckzinward- 1y therefrom at a point adjacent the ends thereof.

'2. In a reversible window shade, the combination of a sheet of fabrlchavmg'hem's of equal size'at either end, and'securing'means including substantially cylindrical clamps arranged to embrace the mounting for said fabric and having a portion'cut out therefrom to define a substantially skeleton structure and having substantially triangular projections'struck inwardly adjacent its ends to be received in said mounting.

In testimony whereof I'affiX my signature.
