Patented Feb. 3, 1931 UNITED ANDREW CHRISTIAN HANSON, on RACINE, wIsooNsIN CONTROLLING DEVICE FOR SHADES I Application filed July 20, 1928. Serial No. 294,069(

This invention relates to improvements in controlling devices for shades.

It is a primary object of the present invention to provide a curtain or shade roller fixture by which the curtain is retained at any desired height, and in which the need of a spring in the curtain roller is eliminated.

A further object of the invention is to provide a curtain roller fixture which when 1 applied to the end portion of a curtain roller, will very satisfactorily balance and tension the curtain at different positions of ad ustment. r

A further object of the invention is to provide a controlling device for curtains or shades which holds the shade in any adjusted position and in which the tension of the shade in any of its movements is not varied.

A further object of the invention is to provide a curtain roller fixture having improved friction brake means for holding the roller in any position, said brake means being adjustable as to the amount of friction to slut the requirements of various curtalns.

A further object of the invention is to provide a controlling device for shades which is simple in construction, inexpensive to manufacture and install, strong and durable, and

well adaptedfor the purposes described.

With the above and other objects in view, the invention consists of the improved ourtain roller fixture, and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing, in which the same reference charactersindicate the same parts in all of the views:

Fig. 1 is a front view of a window and shade therefor mounted on a roller, one end portion of the roller being engaged by the improved controlling fixtures;

Fig. 2 is a side view on a larger scale of the curtain roller fixture looking at the roller engaging portion; 7

Fig. 3 is a sectional view taken on the line 33 of Fig. 4;

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 2, a portion of the curtain roller being shown in attachment with the device;

Fig. 5 is a view showing the opposite side of the device from that shown in Fig.2, part of the casing being broken away;

Fig. 6 is a perspective View of the bracket and outer casing; and V :Fig. 7 is a perspective view of the drum.

Referring now more particularly to the drawing it will appear that the numeral 8 designates a window casing and'9 a window sash mounted therein, and adapted to be covered bya shade or curtain 10 which is secured at its upper end portion to and adapted .to be rolled about a roller 11 horizontally mounted at the upper portion of the casing. One end portion of said rolleris journaled in a bracket- 12 of ordinary construction, while the other end portion has a sleeve 13 secured thereto by pins 14. The outer end of the sleeve 15. is smaller in diameter than the main portion and has a closed end 16 whichis provided with'a pair of openings 17. f The openings are engaged by lugs 18 which are stamped from and project out of the outer end of a drum. 19 forming part of the improved rollercontrolling fixture, the latter being indicated generally by the numeral 20. 1

The controlling. fixture comprisesan outershell '21 whichis-open atone side and which has its other side stamped inwardly to form a cylindrical projecting portion 22 and also forming a recess 23 in the side of the casing. Within the casing and surrounding the cylindrical portion 22 is a washer 24.

I The drum 19 is open at one end, the said opening fitting over the projecting portion 22. The outer periphery of the drum is formed with side flanges '25 between which a tape 26 is wound. Oneset of flanges are adapted to bear against the washer 24.

. The closed endof the drum' in addition to having lugslS extending therefrom is provided with a central opening 27 through which a bolt 28- eXtends. .The bolt alsoextends through an opening 29 in the central part of. the cylindrical projecting portion 22. On the end of the bolt is a lock washer. 30 and a pair of. nuts 31. It may readily be seen that by tightening the bolt the drum may be caused to engage the Washer-24 with any 1 desired degree of friction between the two.

The casing is provided with an opening 32 through which the tape 26 is adapted to extend. The casing is also formed with a suitable bracket 33 having openings 3 1 by which it may be secured to the window frame. It is obvious that the-exact form of bracket may be varied to meet the requirements of various types of windows. The bracket may be so constructed that the device may be secured to the inner edge of the window frame instead of the outside of the frame as shown.

In use, a curtain is mounted, as at Fig. 1 with the end of its roller containing the s eeve 13 engaged by the lugs 18 of the drum 19 of the fixture. The shade may be lowered by pulling it downwardly with the ordinary shade cord and it is retained in any adjusted position by the friction brake means comprising the washer and means for causing the drum to bear against said washer. When the curtain is lowered the tape 26 is wound up on the drum, and to raise the curtain the tape is pulled downwardly, unwinding the drum-and turning the rollerto wind'the curtainthereon. As ,mentionechthe degree of pressure exerted on the washer may bevaried by adjusting the bolt 28. For a large heavy curtain, it will be necessary to have the drum engaging the washer with considerably more pressure than for a small light weight curtain. The screw may be set when the fixture is installed and it is unnecessary to vary the adjustment thereafter.

From the foregoing description it will be seen that the improved controlling device for curtains or shades is both simple and novel and is well adapted for the purposes described.

What I claim is:

1. A curtain roller fixture comprising a cylindrical casing having an openend and a and adjustable means for causing said drum to frictionally engage the washer.

3. A curtain roller fixture comprising a cylindrical casing having an open end and a closed end, said closed end being stamped inwardly to form a cylindrical projection within the casing and to form a recess on the outside, said projection having a perforation therein, a drum having an open end and a closed end revolubly mounted within said casing, and having its open end positioned around said cylindrical projecting portion of the casing, said closed end of the drum beingformed with means for engaging an end portion of a curtain roller and being also formed with a perforation, a bolt extending through the perforation ofthe drum and of the projecting portion of the casing, and a nut threaded on said bolt within the recess formed by theprojecting portion, said In testimony whereof, I afliX my signature.
