Prongs i6 are welded or Vin .any other mannersecured or forniedupon the flange la and extendinto thevvendsfoflthe iutes i3jor;gripping the edges of anwindow'shade or screenwhich is mounted on the roller. The cap I4 has a tubularhub portion leb. AThe cap 1 5 Ais also provided with `flange |511 which has several .prongs Igt` con- "nested-'therewith and extendedinto the end portionsjoflftheglutes i3 :ofthe tube l2. v4A `peg l1 isf-mountedcentrallyonlthe oapl. 4Thishpeg is .adapted-to engagea window trame bracket I8 formed with Vafcircular opening i9 into which the peg yengages. The bracket I8 is provided .with flange portions'.l8a engaged by fastening elements 2B by which the bracket is secured to .a-Window frameiZl.

AA shaft `22 is -rotativelymounted through the Yhub'portion It!b of the cap I4. lAnon-circular peg 23 .is rxedly mounted uponthe outer end vofthe tubularshaft 22. vy'Ilfie-outerend of this shaft is formed with a flange 22a. A ratchet disc `2li is fxedly mounted uponthe shaft 22 immediately vl.adjacent the .flange 22e. `This .ratchet disc l enga'ges.-.against the fface of thebase Wali vof the.. cap .14. l.collar 25 isxedly mounted upon the tubular shaft 22 immediately adjacent the inner end of the tubular hub portion I4". Thus the shaft 22 is rotatively supported.

The non-circular peg 23 engages a wall bracket 26 which is formed with a non-circular opening 2I adapted to receive the non-circular peg 23. The bracket 25 is provided with lugs 26B through which fastening elements 20 are engaged for securing the bracket to the window frame 2|.

When the bracket 26 is attached to a window frame in the position as illustrated in Fig. with the round part of the opening 2'I at the bottom, then the peg 23 will be held in the position in which the ratchet 24 has the ratchet opening 24a at the bottom. With this arrangement the ratchet and pawls 28 are inoperative because with the ratchet opening 24aL at the bottom, the pawls are incapable of engaging the opening. The roller is now adapted to be used for a screen, since the screen will then be free to be pulled out or drawn in, depending upon the way the window sash is moved.

If the bracket 26 is turned around so that the rounded portion of the opening 21 is at the top, as illustrated in Fig. 10, then the peg 23 is held in the position so that the ratchet 24 has its opening 24a at the top. The pawls 28 will now be capable of engaging the opening 24a of the ratchet which is now operative. With the parts in this position the roller may be used for a Window shade. The peg 23 is formed-.in the small opening 23a which is used to receive a shaft to assist in Winding the spring of the roller.

Pawl and ratchet; means is mounted on, with the cap I4 and is cooperative with the shaft 22 to latch the roller in certain wound positions. This means includes a pair of pawls 28 which are pivotally supported by pintles 29 on the base wall of the cap I4. These pawls are adapted to coact with the ratchet disc 24. This ratchet disc comprises a disc-shaped element having a cutout 24a in its periphery into which the tip ends of the pawls 28 are adapted to engage.

A spring 30 is coaxially extended along the shaft 22 and acts between this shaft and the cap I4. More particularly, the spring 30 has an end 30a which is engaged into a cut 3| formed in the end of the shaft 22. The spring 3D has its other end 33h engaged through several lugs 32 stamped from the base wall of the cap I4. A fiber tube 33 is mounted around the spring 30 to encase it. This ber tube has its inner end engaged over the lugs 32 and its outer end supported by several prongs 34 stamped from the bottoms of the utes I3.

There is means for holding certain of the roller tubes in various adjusted positions. This means includes several H-shaped cutouts 35 formed in the material of the tube II. A leaf spring 36 has downwardly projecting portions 36a and is laced through said H-shaped cutouts 35 in a manner so that the projections 36a resiliently engage certain ones of e, group of cutouts 31 formed in a longitudinal line along the length of the roller tube I0.

The arrangement is such that the tubes I 0 and II may be pulled apart or pressed together, and during the motion thereof the resilient projections 36 will snap into and out of the openings 3'I. Thus these roller tubes may be left in any relative position desired.

There is also a means for resiliently connecting certain of the roller tubes. This means comprises a transverse disc 43 extended across a portion of the tube II and having a ange 4I)a formed with several outwardly projecting prongs 4I engaging small openings 42 formed in the material of the tube II to hold the disc stationarily in position. A spring 43 has one end 43a threaded through loop shaped lugs 44 stamped from the material of the disc 4U. The other end 43b of the spring 43 engages against the base wall of the cap I 5 for urging the roller tube I 2 outwards.

The caps I4 and I5 have several prongs 45 stamped from the side walls thereof and engaging openings 46 formed in the roller tubes for the purpose of assisting in holding said caps I4 and I5 in position. 'I'he tube I2 has several prongs 41 stamped from the side wall thereof and cooperative with small openings 48 formed in the tube II for limiting outward projection of the roller tube I2.

In Figs. 11 and 12 a modified form of the invention has been disclosed which distinguishes from the prior form in several respects. This window shade and screen roller has a pair of telescopically engaged roller tubes I0 and II which are formed with the longitudinally extending utes I3 slidably connecting the same. A cup shaped cap I4 and its associated parts is mounted upon the outer end of the tube I0 similar to the arrangement disclosed in the preferred form of the invention, like parts being identified vby like reference numerals. A cup shaped cap I5 is mounted upon the outer end of the tube II.

A disc has a ange 40a with projections 4I engaging in small openings 42 formed in the material of the tube I0. This disc 40' has a hub portion 4l]b through which a screw 50 is coaxially, threadedly engaged. This screw 50 supports a disc 55. A spring 43' is supported at one end 43D to several loop shaped lugs 44 stamped from the material of the cap I5. The other end 43a of the spring is free and rests against the disc 55. The disc is Welded or in any other way iixedly mounted on the screw 5U.

In other respects this form of the invention is similar to the previous form and like parts are identified by like reference numerals.

The operation of the device is as follows:

A Window shade or screen may be mounted upon the roller by engaging the edges beneath the prongs I6 and securing the prongs in position. The spring 30 will be wound up when the shade or screen is drawn and will re-wind the shade or screen as desired. The ratchet 24 and pawls 28 will cooperate to hold the shade or screen extended. If desired, the screen may be attached to one edge of the sash of the window, and in that case the pawl and ratchet must be rendered inoperative. This can be done by turning around the bracket 26 as previously explained.

Because of the feet that the peg I'I and the non-circular peg 23 are disposed within the caps I5 and I4 respectively, the ends of the roller will engage quite close to the sides of the window frame. Thus the edges of the shade will be correspondingly located.

A feature of the first form of the invention resides in the fact that the roller tubes I0 and II may be relatively adjusted to Windows of different w'idths. The tube I2 is resiliently supported so that it may be forced inwards at any time that it is desired to mount or remove the roller from the window frame.

A feature of the invention shown in Fig. 11 is the fact that the tubes I0 and II may be separated, and then the screw 5I) adjusted to any extended or retracted position to approximately adjust the overall length of the roller when these tubes are reassembled. The spring 43' engages against the disc 55 to hold the roller I I resiliently so that it may be forced inwards a small distance to permit the shade roller to be mounted or removed from position. f
