SHADE FASTENING'.

Application filed November 13, 1920, Seriali No. 423,536. Renewed August 28, 1924.k

To all 'whom t may concern Be itY known that I, STEWART HAn'rsHoigN, a citizen of the United States, and a resi- .:zdent of Short Hills, county of Essex, and

State of New Jersey,r have inventeda certain new and useful Shade Fastening, of which the following is a specification.

The invention relates to window shade rollers, and more particularly to devices for or for securing other articles, rsuch as drapery, to poles or other supports.

The objects of the invention are to provide means for securing shades or the like `to hollow members, such as tubular shade rollers without interferencek with the contents ofthe roller; by means of which the shade ,may `he firmly securedr in place without` injury to the roller; by means kof which the shade may be secured to the roller continuously for the entire length of the roller `whethery the latter be of Wood or metal; to provide means for securing the shade in position on the roller without the useof tools, and which will prevent puckering or wrinlling of the shade, and to providey means whereby properly alining` the shade on the rollerjmay be facilitated. j

y.These and further objects will more fully appearwin the followingspecification and accompanying drawings considered together or separately. j y

One embodiment of the invention is illustrated in the accompanying drawings in whichI like parts in all of the figures are Y z beingr omitted.

The invention will lirstbe y,described in connection with a tubular sheetz metal roller such as is commonly known as a ftinv roller. In the drawings l designates such a roller which is rolled to form andsoldered, as, is common. One end of the roller is provided with a rectangular yspear 2, and thev opposite end carries a cylindrical pin 8 by means of which the roller withthe shade 4 attached 1s mounted in a window frame.

The roller is rprovided with a series of perforations 5 and an equal nui'nberk oflon-A gitudinal slots 6, as` shown, by means of which a fasteningstrip 7' may be secured to the surface of the roller. M

.The strip is preferably curved laterally to conform to the surface ofthe roller,` and is provided at one end with a spur 8 which projects longitudinally ofthe stripbut on a slightly lower plane. At the opposite end the strip is provided with triangular lip 9 which isl folded along its `base and. under the strip and parallel thereto for a portion at least of its length.y y,The extremity: of the lip may be bent `dovviiward eccentrically with relation to the strip as shown in FigsA 5 and 6. i f l j f When it is desired to apply a shade to the roller, the end edge of the cloth is `laid longitudinally rof the roller vanduin, Such a position that the vperforations. 5 and slots 6 are covered. rlhe cloth over the perforation is now pierced by the spur8 andthe latter, when the strip ismoved; toward the position parallel to the roller.is shoved forwardv into the bore yof the roller, the slight bend l0 in the spur will permit the fspur to lie parallel with, andagainst the wall of the roller when the body of the strip is in position resting on the cloth and'parallel with the outside of the roller.V

Before the strip assumes the last mentioned position the Vapex'of the lipv 9 is pushed through the cloth and through the slot 6 nearest the perforation 5, Thelipped end is then moved laterally with respect to the roller, forcing the lip into the same and into frictional engagement with the wall of the bore thereof. The shade is then folded back over the strip and aroundthe.

Cfr

are similarly disposed along the roller whereby the entire edge of the cloth, except the slight gaps between the strips and short spaces at the ends of the roller, is securely attached to the roller while the cloth is pei'- forated at relatively wide intervals only. The pull of the shade on being` unwound will tend to hold the lip 9 in the slot 6, and the said slot may be of any length desired whereby strips of various lengths may be used.

Instead of placing the spur at the extremity of the strip as shown in Figs. l, 2 and 3, the spur 22 may be cut out at some distance from the end of the strip 23 as shown in Fig. 7.

In Fig. 8 the lip 24, instead of being located at the end of the strip, as before, is positioned a short distance from the end. By the use of the construction illustrated in Figs. 7 and 8 the strips used at the ends of the roller may extend over the ferrules, when used, and to the extremities of the roller, and the shade will be secured to the roller for the entire length thereof.

In accordance with the provisions of the patent statutesthe principle of the inven tion, together with what is now considered to be the best embodiment thereof, have been described, but it is to be understood that the apparatus described is merely illustra tive, and that the invention may be carried out in other ways.

The invention having been described what is claimed and desired to be secured by Letters Patent, is

l. An article of the class described, comprising a roller, there being a perforation in the roller, a member adapted to extend longitudinally of the roller, means for engaging one end of the member within the perforation, there being a longitudinal slot in the roller, and means extending transversely of the roller for engaging the slot and securing the opposite end of the member to the roller.

2. A device of the character described, comprising a tubular sheet metal roller of uniform cross section, there being a perforation in the cylindrical surface of the roller, a member adapted to extend longitudinally of the outer surface of the roller and in proximity thereto, a spur projecting from the member and adapted to engage the interior wall of the roller, there being a longitudinal slot in the cylindrical surface of the roller and at a distance from. the perforation, and means carried by the member and extending through the slot for elastically engaging the interior wall of the roller for securing the member to the roller.

3. A device of the character described. comprising a tubular sheet metal roller of uniform cross section, there being a perforation in the cylindrical surface of the roller,

a member adapted to extend longitudinally of the outer surface of the roller and in proximity thereto, an integral spur projecting from the member, said spur being on a different plane from the member and adapted to engage the interior wall of the roller, there being a longitudinal slot in the cylindrical surface of the roller and at a distance from the perforation, and offset means integral with the member for passing through the slot and elastically engaging the interior wall of the roller for securing the member to the roller.

4. A device of the character described, comprising a tubular roller, there being a series of spaced perforations in the roller, said series extending longitudinally of the roller, there being a series of longitudinal slots in the roller, each slot being in approximate alinement with a perforation, an elongated member extending longitudinally of the roller between a perforation and a slot, a spur carried by the member, said spur being on a plane different from the body of the member, whereby said spur may engage the interior wall of the roller through the perforation, a lip carried by the member, said lip extending below and substantially parallely and transversely of the member and adapted to engage the interior wall of the roller through the slot.

5. A device of the character described comprising a tubular roller, there being a series of spaced perforations in the roller, said series extending longitudinally of the roller, there being a series of longitudinal slots in the roller, each slot being in approximate alinement with a perforation, an elongated member extending longitudinally of the roller between a perforation and a slot, a spur carried by one end of the member, said spur being on a plane different from the body of the member, whereby said spur may be passed through a perforation and engage the interior wall of the roller by movement of the member longitudinally of the roller, a lip carried by the opposite end of the member, said lip extending below and substantially parallel to and transversely of the member and adapted to engage the interior wall of the roller through the slot by movement of the lipped end of the member transversely of the roller.

6.
