Application July 27, 1944, Serial No. 546,813

zfllaims. (Cl. 160390) This invention relates to means .for fastening a conventional window shadeto a shade roller, and is particularly concerned with means mounted on the roller and detachably engaging the shade so that a worn or mutilated shade can be quickly removed and a new shade'easily and accurately attached by the housewife.

In a collateral way, the invention is likewise concerned with attaching a reversible shade to a roller. In this type of construction, the positioning of the shade on the roller may be reversed after the exposed portion of the shadehas been soiled or worn.

'One of the prime objects of the invention is to provide simple, practical and inexpensive attaching means which can be readily mounted on the roller, and by means of which a shade can be attached or removed, anda new shade substituted by the housewifewithout in any manner marring, tearing or otherwise disfiguring the shade in the vicinity of the point or points of attachment.

Another object is 'to provide a shade attaching means of very simple construction which can be easily and inexpensively manufactured and mounted in attaching position on the roller with great facility.

A further object is to provide an attaching means to which a shade may be quickly, accurately and easily attached and/or detached, which requires no tools to manipulate, and which when the shade is in position, lies fiat against the roller body so that [there is no interference with the winding operation, nor is there any difference in the appearance of the shade when wound.

The foregoing and other objects are attained by the means described herein and broadly disclosed in the accompanying drawing In the drawing:

Fig. 1 is a fragmentary, elevational view of a shade roller and shade showing my shade attaching clasps secured thereon.

Fig. 2 is an enlarged view showing the blank Fig. 8 is a side, elevational view similar to Fig.

such as is at present in general use, a window shade l6 being attached thereto and is windable thereon, and this shade can be formed of any desired material.

The present invention is directed to a shade attaching means or clasp so designed that it can be readily mounted in position, and by means of which a shade may be permanently secured to a roller, or by means of which the shade may be detachably secured in position.

The shade attaching means is mounted on and secured to the roller l5 and can be either a stamping formed of relatively thin, readily bendable material with prongs formed integral therewith, or it can be a stamping having tacks assembled thereon, the principle, mounting, and operation being exactly the same.

Referring now more specifically to Figs. 2, 3. 4, 6 and 9 of the drawing in which I have shown prongs formed inte ral with the clasp. The numeral l1 indicates a stamped blank, shaped as clearly shown in Fig. 2 of the drawing, the end sections I8 forming wings, bent on the line l9 and foldable over and onto the main body, thence the ends are again bent on the line 20, at right angles to the body, so that the wing extends vertically, as clearly shown in Figs. 3 and 4.

Relatively sharp prong sections 2| are formed integral with and project from the edges of the body of the stamping, these prongs being bent on the bending line '22 so that they project downwardly as shown in Fig. 3, so that they readily pierce the body of the roller l5, and firmly anchor the clasp in position. These clasps are mounted in longitudinally, spaced apart, relation on the roller as shown, the spacing from the one side edge of the roller being uniform at all times.

Openings 23 are provided in the shade material l6 at a point directly adjacent the one end thereof, the opening 24 being spaced at predetermined distance from the one side edge of the material, the spacing of the intermediate openings being standardized so that any suitably prongs, and in Figs. 8 and 9 the clasp has but two'prongs, this two-prong construction requires 7 slightly less material, but the principle of at-' 'tachment and operation is exactly the same.

In Figs. 5, 6, 7, 10 and 11 I have. shown a slightly modified construction in which the. prongs 2! are omitted, openings 25 being punched in the blank l1, and these openings accommodate small tacks 26 which are inserted therein,

Figs. 6 and '7 showing a two-tack design, while Figs. 10 and 11 show but a single tack arrangement fOr anchoring. f

If it is desired to permanently attach the shade to the roller, the shade is first placed in position and the clasps utilized as tacks, the wings lying flat against the roller, and the shade can of course be cut or torn free when desired, so that a replacement can be added and secured by the wings, this makes a very satisfactory arrangement as the strain on the clasp is limited due to the material being wound on the roller.

To facilitate the attachment of reversible shades, I provide openings 21 in the lower hem of the shade in which the stiffening slat 28 is mounted, these openings face the outside whenthe shade is hung, so they are not visible from the interior, and when it is desired to reverse the shadeQthe thread 29 forming the lower hem is removed, the shade is then reversed end for end and the perforations 23 and 2 4 will reglste with the clasps, the hem is then provided in the previously attached end and the shade is ready for use.

This attaching means insures accurate parallel anchorage of the shade, it will wind up evenly, and it further permits the shades to be adjusted to uniform length in multiple windows.

The herein described construction and arrangementadmits of considerable modification without departing from the invention; I therefore do not wish to be limited to the precise arrangements shown and described, which is broadly for the purposeof illustration, as the scope of protection is to be taken solely from the appended claims, interpreted as broadly as is consistent with the prior art. I

What I claim is:

1. Thecombination with a shade roller, of a fastener permanently anchored to the roller for detachably attaching a shade provided with spaced-apart perforations therein, said fastener comprising a body portion formed of relatively thin material with relatively sharp depending means embedded in the roller for anchoring the fastener in said roller, and vertically disposable bendable wings formed integral'with the fastener bendable over the body portion with the end sections bent upwardly and projectable through one of said perforations and bendable over the shade adjacent the perforation to secure the shade on the roller. I

2. The combination with a shade roller of a fastener permanently anchored to the roller for 'detachably securing a shade provided with a plurality of perforations along an end thereof, said fastener comprising a relatively thin sheet metal stamping provided with relatively sharp depending prong members formed integral therewith and embedded in the roller for anchoring the fastener, in position, elongated wings formed integral with the main body and foldable over and onto the-main body of the stamping, with the end secure the shade over said fastener; body.
