controlling devices for window shades. Itv is one of the objects of the present invention to provide a fixture for one end portion of a curtain or shade roller providing for the. retention ofthe curtain atanydesired height and eliminating the need of a spring in the curtain roller.

A further object of the invention is to providea curtain roller fixture which, when applied to the end portion of a curtain roller, will very satisfactorily balance and tension the curtain during its various movements and at anyposition' of adjustment. J

A further object of=the invention is to provide a curtain roller fixture having friction means which is adjustable from the exterior of the fixture for holdingthe roller in any desired position. Y i

A further object of the invention is to provide a curtain roller fixture which, when applied to a window casing, is'neat and attractive in appearance and which, is very simple mechanically and 'canbe manufactured very reasonably. A-further object of the invention 1s to providea curtain roller fixture which is of very In the accompanying drawings illustratingfone complete embodiment of the preferred form of the invention, in which the same reference characters indicate the same pa'rts'i n'all of the views Fig. 1 is a front view of a window casing and window sashes equipped with a shade embodying the'improved controlling device of ordinary construction and mounted at its otherend in the improved fixture, parts being broken away andpartsbeing shown in section to bring out the details of construction;

Fig. 3 is a front view of the improved ourtain roller fixture shown mounted on a portion of a window casing; I I

Fig. 4 is an enlarged vertical sectional view of the fixture;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 2; and

- Fig. 6 is a broken away view showing a portion of the casing with an edge view of the improved fixture in connection therewith.

Referring now more particularly to the drawings it will appear that the numeral 8 designates a window casing having window sashes 9 slidably mounted therein. The window sashes are adapted to be covered or shaded to any desired degree by a shade or curtain 10 which is secured at its upper end portion to and adapted to be rolled about a roller 11 mounted horizontally at the upper portion of the casing. One end portion of said roller is covered by a metal ferrule 11 of ordinary construction, and a stud 12 projectingoutwardly therefrom is journaled in a bracket 13 of ordinary construction which is mounted onone side of the upper portion ofthe Window casing. The other end portion of the roller 11 carries a metal ferrule 14 of a' somewhat modified construction. By reference particularly to Figs. 2 and 5 it will be noted that said ferrule 14 has its outer faceformed with a slot or-opening 15 of rectangular shape, and the stock stamped out of said face to form the opening is bent inwardly, as at 16, to extend toward the end portion of the roller 11. Said ferrule 14 is adapted forrev oluble engagement with the improved curtain roller fixture indicated generally by the numeral 17 which will now be described in detail.

Said-curtain roller fixture 17 is mounted on the upper portion of the window casing 8 opposite the fixture 12. The body of said fixture 17 is cup-shaped, and extending from opposed side portions of the annular wall 18 against the inner surface of the bottom or end 21 thereof is a disc 22 having inwardly projecting'portions 23 stamped therefrom and extending inwardly to form a drum.

-The disc 22 is revolubly mounted on the shank of a rivet 24, the latter being connected to the central portion of the end 21 of the w0und around the four projecting portions as indicated in Fig. 4. The annular side wall 18 of the fixture is provided with an,

opening 26 through which the tape or cord 25 extends. A curved braking strip 27' is formed at one end with a depending lug 28 which fits into an opening 29 ofthe casing,

j and at its other end with an opening 30 through which the. tape is adapted to be extended so that it'may depend downwardly along. the side ofthe window casing. The braking strip 27 is bowed outwardly slightly from the side of the casing so as to normally engage thetape onlylat a point adjacent the opening 30. A. screw 31, "which extends through an opening 32 of the braking strip,

is threaded into the side of the casing. By adjusting said screw, the amount of pressure placed upon the tape by the strip 27 may be varied. The extreme lower end of the tape 25, maycarry aring 33 for convenience in operating i In use,'a curtain roller is mounted in the manner shown in Figs. 1 and 2, with the clon gated projecting portions 23 of the drum of the fixture extending into the opening of the end ferrule 14 of the roller. The shade may be lowered by pulling it downwardly in the ordinary manner with the ordinary shade cord, and it is retained in any adjusted position because of the frictional engagement between the braking strip 27 and the tape 25; When thecurtain is lowered the tape 25 is wound upon the drum forming projecting.

portions28of the fixture, and to raise the curtain the end portionof the tape 25 is pulled downwardly, unwinding the tape from the drum and turning the drum and curtain roller in adirection to efiect the rolling or winding of the shade upon the curtain roller. As 1nentioned,.the degree of frictional engagement between the braking strip 27 and the tape 25 may be adjusted by loosening or tightening the screw 31. For a large heavy curtain, it is desirable to have more of a frictional engagement between saidparts than when a light curtain is used. As shown in Fig. 6, the head of the screw 31 is readily acof a curtain roller, a flexible member wound on said drum and extending exteriorly thereof, operation of said flexible member serving to rotate said drum and roller to raise the curtain,-, and braking means positioned exteriorly of the casing and engageable'with the flexible member for pressing the flexible member against aqca'singportionto hold the curtain in any. position of adjustment.

2. A curtain roller fixture, comprising a casing, a drum revolubly mounted therewithin and engageable with the end portion of a curtain roller, a flexible member wound on said drum and extending exteriorly thereof, operation of said flexible member serving to rotate said drum and roller to raise the cur tain, braking means positioned exteriorly of the casing and engageable with the flexible member for pressing the flexible member againsta casing portion to holdthe curtain in any position of adjustment, and means in connection with said braking'means for adjusting the pressure exerted thereby on the flexible member'to suit the requirements of curtains of different weights.

3. A curtain roller fixture, comprising a casing, a drum revolubly mounted therewithin and engageable with the end portion of a curtain roller, a flexible memberwoundon said drum and extending exteriorly thereof,

operation of said flexible member serving to rotate said drumand'roller to raise the curtain, and a'curved braking strip positioned exterior-1y "of the casing for pressing the flexible member against a casing portionto hold the curtain in any position of adjustment.
