ments inshade rollers, and more particu` larly to means for supporting the end of the roller and controlling the spring within the roller.

In the type of roller to which my invention relates, there is employed a non-rotatable plate and a rotatable disk, the two having opposed recesses for the reception of balls or other movable members to lock the roller in the desired position.

rllie object of my invention is to so simplify the construction as to reduce the lininber of parts to the minimum, and to render Vthe device readily attachable'to or detachable from the roller.

Both ends of the spring in my improved shade roller extend to the same end of the,

roller, and two separate plates are provided non-rotatable in respect to each other, and one oi which coacts with the disk on the spindle and the other of which servesthe double purpose of holding the two plates against rotation in respect to the body of the roller, and of holding one end of the spring againstl rotation in respect 'to the spindle.

Reference is to be had to the accompanying drawings, forming a part of" this speciication, in which similar characters ot reference indicate corresponding parts in all the gures, and in which- Figure 1 is a side elevation of a shade roller constructed in accordance with my invention, a portion of the outer cap and av portion of the body of the roller being broken away; Fig. 2 is an end view of the roller shown in Fig. 1, the cap being removed; Fig. 3 is a longitudinal section through the'roller, said section being taken on 'the line 3 3 of Fig: 2; Fig. ft is an inner end view of the attachment of the shade roller, the body of the roller being removedr and the spindle being shown in section; Fig. 5 is an end view similar to Fig. 2, but showing-the parts in locked position; Fig. 6 is a longitudinal section through a second form which my invention may assume, said scction being taken on the line 6 6 of Fig. 9; Fig. 7 is an end view of the roller shown in Fig. 6, the cap being removed; Fig. S is a longitudinal section of the roller shown in 141g. G, said section being tairen on the line S-S of Fig. 9; Fig. 9 is an inner end view of the rollershown. in Fig. G, the body oi the roller being i'emoved and the spindle being shown in seetionglFig. 10 is an end Vview oi theroller shown in Fig. 6, the cap being removed and the parts being in locked position; and Fig. 11 is a perspective view ot' the inner plate of the form shown in Figs. 1 to 5, inclusive.

In the specific form of shade roller illustrated in- Figs. 1 to 5, inclusive, there is em- -ployed a body 10 of any suitable material, preferably of wood and provided with a central passage 11 extending into one end. Concentric with this passage is a spindle 1Q, non-cylindrical in cross section and projecting beyond the end of the roller to support the latter. Surrounding the spindle and within the passage 11, is a double helical spring 13, both ends of which are disposed l adjacent the same end of the roller. rlhe main features of my invention reside in the means :t'or securing the ends 'of this spring and in controlling the relative movement ot the spindle and the body. For accomplishing this, I provide two plates 14 and 15 and a disk 16. The two plates 1st and 15 are both formed of sheet. metal cut and stamped to the desired forni, while the disk 1t? is formed of somewhat greater thickness than either plate and is held within a recess in the plate 15. The plate 14, shown in perspective in Fig. 11, serves three functions, namely; to hold the two plates against relative rotation, to prevent rotation of the two plates in respect to the body, and to hold one end of the spring. -The plate 14k is provided 'With a central body portionk 17, having two outwardly-extending' arms 18, 18, at opposite sides thereof. Each arm, adjacent its .inner end, is provided with a bead or corrugation 19, serving to receive one end of the spring 13, and the outer end of each arm is provided with lugs 20, adapted to enter recesses in the end of the wooden body to lock the plate against rotation in respect to the body.

The central body portion 17 of the` ioo plate is provided with flanges 21,' extending outwardly from the plate inthe oppositedirection from the flanges and adapted to engage with the plate to lock the two y, plates'against relative rotation, as is indicated in Fig. 1. stated, is formed of sheet metaland is The plate 15, as previously stamped to form a central cavity or chain- -v .ber 22 of a diameter and` depth substantially equal tothe diameter and thickness of the idisk16. At diainetrically opposite points,

the cavity or chamber is provided with eX- tensions or pocketsv 23, adapted to receive small balls 24 constituting the locking means for the roll-er. The disk 16 -is provided with Y,

recesses or pockets 25 in the periphery there- ,'o, at diametrically opposite points, whichr coperate withI the balls 24 in the pockets 23. When the roller is rapidly rotated, the balls are thrown out into the pockets 23 and donot contact with the disk 16. When the roller is stopped, the ball at'the upper side of the roller may drop down linto one of the pockets 25, so that upon an attempted rotation of the body of the roller in one direction, a'ball will enter the recess 25 and lock dicated in Fig. 5.

the roller against rotation, as is clearly in- The two plates are held in engagement with the end of the body of the roller by a suitable metal cap 26, so that,

the lugs 2O cannot become disengaged from the end-of the body of the roller. 'As will be noted particularly in Fig. 1, the lugs 2() i hold theplate 14against rotation in respect to the body,the lugs 21 hold the two plates against rotation in respect to each other, the plate 14 holds one end of the coil spring, while the opposite end is secured to the spindle. In this form, both of the plates' arev formed of sheet metal.

. In Figs. 6 to 10, inclusive, l have illustrated a somewhat diierent form, in which the same body 10, spindle 12, spring 13, cap

' 26 and balls 24, are employed, but in place and 15, employ two plates 14a and 15a of somewhat different construction. The plate 14a is formed from sheet metal and serves the same three Afunctions asthe plate 14 above described. The plate is provided with downwardly-extending lugs 27, 27, eut and stamped up from the body of the plate and adapted to enter recesses in the end of the wooden body 10, to

of the two plates 14 'prevent rotation of the plate in respect to from the edge, so,

xvliich'latter is eut trom a plate of substantially the same thickness as the disk. lihe late 15a has a central aperture 22a, to receive the disk 16, and pockets 23a at the sides thereof to receive the balls 24. The plate 14L forms a bottom :tor this central recess and side pockets, inasmuch as said recess and pocketsare cut entirely through the plate i 15a. The two plates are held to the end of the body vby the cap 26, and the general op-` eration is substantially the same as that in the form first described.
