' a simple and eflicient means whereby ac'urtain or shade may be attached to the roller.

The ,invention consists in the novel construction and combinations of parts which will be hereinafter fully described and claimed.

In the drawings :-Figure 1 is a front viewof my improved roller. Fig. 2is asimilar view including a window shade or ourtain, and the means for securing the curtain or shade to the roller. Fig. 3 is a section, enlarged, on line 3-3 of Fig. 2. Fig. 4 is a view of one of the springs forholding the curtain in placeupon the roller. Fig. 5 is a longitudinal section, partly broken away, of the inner-section of the telescopi crbody portion of the roller and the parts carried thereby. Fig. 6 is a view of the right hand end of the section of the roller shown in Fig. 5. Fig. 7 is a view similar to Fig. 6, with the end head of the roller removed therefrom. Fig-8 is a section on line 88 of -Fig. 5. Fig. 9 is a plan view of the right hand end of the section of the roller shown in Fig. 5, with the end head of the roller removed therefrom. Fig. 10 is a horizontal section on line 1 0-10 of Fig. 6. Fig. 11 is a view of parts of the spring-contro1led mechanism for rotating the roller. Fig. 12 is a view of the left hand endof the roller shown in Fig. 1. Fig. 13 is a view of the left hand end of the roller shown in Fig. 1, partly broken away. Fig. 14 is a section on line 14-44 of Fig. 13. Fig. 15 is a section on line 1515 of Fig. 12. 2 designates the main body of the curtain roller, the body being formed in two

sections

4 and 6, which are arranged to telescope with each other as I shall presently de scribe. The outer ends of the sections 4: and 6 have secured thereto suitable heads, 7 and 9 respectively. 1

Each of the

sections

4 and 6 .of the body 2 undercut portions of the bind and hold the curtain between the of the roller is formed of sheet metal. The

The section 6 is fitted within the section 4,

the fit between the two

sections

4 and 6 bein such as to permit a telescopic adjustment of the two sections for the purpose of shortening or lengthening the roller as desired, and the frictional engagement of the two sections 1 and 6 with each other holding them metal sheet forming eachsection is first bent groove 13 in in their positions of adjustment. The groove 13 formed in the roller not only serves as an opening into which a curtain, or shade may be inserted and then secured to the roller, but the groove 13 formed by bending the metal also serves as a strengthening or stiffening rib for the entire roll.

Referring to Figs. 2 and 3, 16 designates a part of a curtain, the upper edge portion 17 of which is inserted into the undercut groove 13 in the body 2 of the roller; and also inserted into the groove 13 are substant ally Z-shaped springs 18, each of which comprises two arms 19 and 20, connected by a diagonal part 21, which, when the springs 18 areinserted intothe undercut groove 13, tends to force the arms 19 and 20 apart and into the undercut portions of the grooves.

It will thus be seen that by inserting the upper edge portion 17 of the curtain 16 into the groove 13, and then inserting the springs 18. into the groove, the arms 19 and 20 of each spring will be forced into the .groove and will springs 18 and the inner wall of the groove. of the springs 18 Any desirable number may be employed in securing the curtain 16 to the roller.

The end head 7 is disk-like in form, as shown, the section etand is provided with an inwardly-extending flange 22 which extends part way around the edge of the end head and terminates in end portions 23 having. a space therebetween. The outer ends of the longitudinal edge portions of the section 4;

and it is arranged within the end of are bent inwardly between and into engagement with the end portions23 of'the flange 22, in forming the undercut groove 13, as shown'in Fig. 14, thus holding the end head 7 in lace within the section 4. The end head serves as a means to support the outer end-of the section 4 against being colla sed. In order to prevent displacement o the end head 7 longitudinally of the

sectlon

4, 10 the outer end of the edge portion of the metal forming the section4 is bent inwardly as at 24 (Figs. 12 and 15) into enga ement with the outer face of the end head? 7, and opposite sides of the section 4 are pro- 5 vided with indentations 25 adjacent the mner face of the flange 22 of the head 7. It will thus be seen that the metal displaced by the indentations 25 engages the flange 22 in opposition to the inturned portion 24 of the section 4, to hold the head 7 against displacement longitudinally of the roller. The end head 7 is provided with a central opening 26 therein for the reception of a plvot pin of a suitable bracket upon which t e end head 7 of the roller is adapted to be mounted.

In order to support the inner or free overlapping ends of the

sections

4 and 6 against being collapsed, I provide within the lnner section 6, adjacent the inner end thereof, a suitable block 27 which is held in place by small nails or brads 28 driven through the metal. forming the section 6 and into the block 27. p g

The roller is provided with a suitable spring actuated rotating means which I shall now proceed to describe. Extending centrally through the section 6 of the roller is a shaft 29, the inner end of which extends into an opening 30 in the block 27 in a manner to permit the block 27 to rotate with the section 6 about the shaft 29. The outer end of the shaft 29 extends through a central opening in a head 31 which is adapted to rotate about the shaft 29 and which forms an element of the spring-actuated rotatlng means for the roller, as will presently appear. The head 31 is formed of sheet metal which is cut and bent to form inwardly extending arms 32, which are enga ed by one end of a torsion spring 33 the ot er end of which is engaged with the shaft 29 by being extended through a slot 34 in the inner end of the shaft. The head 31 is arranged within the outer end of the section 6 of the roller, and it is engaged with the inner wall of said section in a manner to prevent the collapse thereof; and the head 31 also extends into the slot formed between the lon- 60 gitudinal edges of the metal forming the section 6 in a manner to cause said section and the other parts of the roller, independently of the shaft 29 and the parts carried thereby, to rotate with the head 31 upon the shaft 29. The outer end of the shaft 29 is flattened, as at 35, and it extends beyond the end head 9 as shown. This fiattened end 35 of the shaft 29 is adapted to be inserted into the slot of a bracket of well known construction in the curtain fixture art, which bracket is adapted, as is well known, not only to support the outer end of thef'shaft 29 but also to prevent the rotation thereof by the engagement of the flattened end of the shaft with the walls of the slot in the bracket. i

The end head 9 is provided with an inwardly extending flange 36, which surrounds the outer end of the section 6 of the roller and which also surrounds the head 31, re- 30 t aining the outer end of the section 6 of the roller in shape between the head 31 and flange 36. The head 9 is arranged in spaced relation to the head 31, and extending from the head 31 and into the space formed be- 35 tween the

heads

9 and 31 are two pairs of

flanges

37, 37 and 38, 38, which extend tangentially with respect to the shaft 29 and which form pockets 39 and 40. Within each

pocket

39 and 40 is arranged a ball 43, each ball 43 bein adapted to roll within its pocket towar and from the shaft 29. Arranged between the pockets 39 and 40and within the spaces between'the heads 9 and 31, is a collar 41 which is mounted upon the flattened end 35 of the shaft 29 in a manner to prevent the rotation of the collar 41 about the shaft. The collar 41 has notches 42 cut therein, forming teeth 44 upon 'the collar. The balls 43 are adapted to engage the teeth 44.0f the collar 41 and the

flanges

37 and 38 of the head 31, in a manner to prevent the rotation ofthe head under certain conditions, as will be hereinafter explained.

The outer ends of the longitudinal edge portions 'of the section 6 of the roller are cut away, forming shoulders 45 (see Fig. 9), against which the inner face of the head 31 rests on one side of the roller, while the inner'face of-the head 31 on the other. side of the roller rests against the metal displaqed by an indentation 46 in the metal forming the section 6. of the roller (see Fig.

5) and the head 31 is held in place against the shoulders 45 and indentation 46 by the

flanges

37 and 38 cut from the metal forming the body of the head 31 and bent and extended into engagement with the head 9,

The head 9 is held in-place with its inner 1 20 face in engagement with the outer end of the metal forming the section 6 of the roller, by projections 47 formed on the outer end of the section 6 of the roller, which projections first extend through slots 48 in the head 9 and are then bent outwardly and then inwardly against the outer face of the flange 36 of the head 9, thus securely holding the head 9 in place. The ends of the spring 33 are so engaged with the head 31 the flattened outer end oi and the shaft 29that when the roller, supported by the brackets as hereinbefore described, is turned in the direction of the full line arrow in Fi 7, the s ring 33 will be wound upon the s aft 29; a er which, when permitted so to do, the spring will, by its own action, rotate the roller in the'direction of the dotted line arrow in Fig. 7.

.. The operation is as follows -Assuming that the head 7 has been mounted upon the pivot stud of a suit-able bracket, and that the shaft '29 is mounted within the slot of the well known curtain fixture as hereinbefore described, it will be seen that the roller may be rotated and that the shaft 29 wil'l remain stationary. The curtain 16 is so wound upon the roller that in lowering orunwinding the curtain from the roller, the roller will beturned in the direction of the full line arrow in Fig. 7, and the spring 33 will be wound upon the shaft 29. After the curtain has been unwound or lowered to the desired extent and is released, one of the balls 43 will roll into one-of the. notches 42 in the collar 41, and will be engaged by one of the teeth 44 of the collar and one of the

flanges

37 or 38, in a manner to lock the roller in position upon the shaft 29 and prevent the action of the spring 33 from rotating the roller torewind the curtain thereupon. 4

When it is desired to permit the spring 33 to rotate the roller and rewind the curtain thereupon, the curtain is first drawn down-' spring 33 to rotate the roller with sufficient ing the movement of the curtain, the speed speed to maintain the balls 43 in the outer portions of the pockets 39, and prevent the engagement of the balls 43 with the teeth 44 of the collar 41 until the curtain has reached the desired position, whereupon, by retardof the roller being turned by the spring 33 will be decreased sufficiently to permit one of the balls 43 to rengage one of the teeth 44 and prevent the further rotation of the roller by the action-of the spring 33, as previously explained.
