As is customary in window shade rollers and the like, one end of the roller is provided 5 with a pintle 5 of circular cross section and the opposite end carries a pintle 6 of polygonal cross section. Within the section lot the roller adjacent the polygonal pintle 6 the customary spring motor (not shown) may be mounted for operating the roller.

For securing the shade web-to the roller I form in each section of the roller :1 channel or trough having undercut sides adapted to have inserted endwise and securely to retain the beaded top edge 7 of a window shade web 8. The beaded edge 7 may be formed on the window shade in any convenient manner, such as by folding and stitching a margin of the web around a cord or filler 9 of twisted paper or the like.

The bead-receiving channel provided in the outer member 1, designated 10 in the drawing, is relatively small, uniform in dimensions throughout its entire length, and adapted snugly to containthe beaded edge? of the shade web 8. As shown in Fig. 2, the channel 10 produces a complementary ridge on the interior ofthe tube 1. A channel, designated generally 11in the drawing, is provided in the member 2. This channel 11 is, at the outer end of the member 2, and through an adjacent portion of themember as shown at 12, uniform in size with the channel 10 of the member 1. At the inner end of the menr her 2, and through a portion adjacent thereto, the channel 11 is deepened and enlarged in cross section, as shown at 13, in order-to receive the internal rib produced in the member 1 by the channel 10, and for a further important purpose now to be explained.

The enlarged channel 13 of the member 2 serves to remove metal from theperiphery of that portion of the member 2 in which the enlarged channel 13 is provided, thus operating to constrict or reduce the diameter of that portion of the member 2.

Additional constriction of the inner end of the member 2 is attained by depressing the seam 14 where the margins of the sheet metal strip are united to provide the tube. This depressionserves to accommodate the internal rib formed in the member 1 by its corresponding seam l5.

The area of the metal removed from the periphery of the member 2 by the depressed seam 14 and the deepened bead-receiving channel 13, operates to constrictthe diameter of that portion of the member 2 sufficiently to permit the member 2 tobe telescopically received within the member 1. I prefer to make the fit of the two members sufiiciently tight to cause themembers to be retained frictionally in any adjusted relative positions.

The two members are associated as has been explained, and the beaded edge 7 of a shade web 8 is inserted endwise in either direction. It will be evident that the beaded edge of the shade will be snugly retained at opposite ends of the roller assembly by the channel 10 of member 1 and by the portion 12 of the channel 11 of member 2. The internal portion 13 of the channel 11 is more than large enough to contain the beaded edge 7, and it is immaterial that the dimensions of this portion of the channel may be too great snugly to retain the adjacent portion of the beaded edge 7, since any stress applied to the shade webis transmitted to and received by the end portions of the channels 10 and 12.

t is to be understood that I have shown and described the present invention in one preferred form of embodiment only merely by way of exemplification. The invention is capable of embodiment in other and further modified forms, but all such modifications, to

the extent that'they embody the principles of the invention as pointed out in the appended claims are to be deemed within the scope and purview thereof.

I claim:

1. An extensible shade roller including a pair of tubular metallic members, the outer ends of which areof substantially thesame diameter, each member being provided with a longitudinal surface channel adapted to receive the beaded edge of a shade wed, .the channel of one of the members being of in creased depth along a portion of the length of the member to constrict the diameter of said member along said portion and adapt .said portion to be telescoped into an end of the other member.

2. An extensible shade roller including a tubular metallic member of uniform diameter throughout its entire length, and another tubular metallic member having one end ofa diameter equal to that of the first member, both of said members being provided with a longitudinal surface channel adapted to receive the beaded edge of a shade web, the

channel in the second member being formed of increased depth along a portion of the member adjacent its other end whereby the diameter of said portion is reduced and is adapted to be telescopically received in an end of the first member.

3. An extensible shade roller including a tubular metallic member of substantially uniform diameter throughout its entire length provided with a longitudinal surface channel adapted snugly to contain the beaded edge of a shade web, and a second tubular metallic member having one end and a portion adjacent thereto of substantially the same diameter as that of the first member and provided with a bead containing channelsimilar to that of the first member, the second member-having its opposite end and a portion adjacent thereto provided with a continuation of the channel of increased depth, whereby said end and adjacent portion of the member are of decreased diameter adapted to be. telescopically received in an end of the first member.

4. An extensible shade roller including a tubular metallic member of substantially uniform diameter throughout its entire length provided with a relatively small longitudinal surface channel adapted snugly to contain the beaded edge of a shade Web, a second member provided with a continuous channel having at one end a portion adapted snugly to contain the beaded edge of a shade web and at its other end a relatively large portion adapted to contain the channel of the first member, whereby the last mentioned end of the second member is constricted in diameter and adapted to be telescopically received in an end of the first member.

In testimony whereof I aflix my signature.

CHARLES WESLEY RICE.
