CURTAIN-FIXTURE.

SPECIFICATION forming part f Letters Patent No. 682,781, dated September 17, 1901.

Application filed July 9 1900. Serial No. 22,917. (No model.)

To a/ZZ whom it' may concern,.-

le 'it known that I, FRED H. BAssE'rT, a cltizen of the United States, and a resident of -Waterbury, in the county of New Haven and the roller-bearings with the cord that the -roller is 'made Aself-adj usting with respect to l its horizontal position and such horizontal po- 1 sition readily and easily maintained.

To enable others to understand my invention, reference is had to the accompanying;

drawings, in which;-

Figure 1 represents a broken front elevai tion of a window-casing with the c-urtain-fixy tures attachedv thereto, showing also the curr tain-roller partially lowered. Fig. 2 is asectional view of the casing and side elevation of the fixtures and curtain-roll looking in the direction of arrow a, of Fig. 1. Fig. 3 is a detail perspective view of the upper left-hand' bracket. of the upper right-hand bracket. Fig. 5 is a detail front elevation ofthe lower roll-frame with the fastening-cleat removed therefrom, said bracket adapted to be secured to the casing below. the center and below the downward Itravel o'f the curtain-roller. Fig. 6 is a detail side elevation of the cord-fastening cleat and its retaining-screw. Fig. 7 isa broken side elevation o'f the left-hand end of the curtainroller with the bearing secured thereto, also 'section of the cord threaded through said bearing. v Fig. 3k is an end elevation of the curtain-roller and side elevation of its bearing looking in the direction of arrow b, Fig. 7. Fig. 9 is a broken'side elevation of the right- -hand end of the curtain-roller, the bearing journaled on a screw in the end thereof and a section of the cord secured to said bearing. Fig. 10 is an end elevation of vthe curtain- Fig. 4 is a detail perspective viewl 5, 6, and 7 are cord-pulleys. The pulley 5,.

Fig. 3, is journaled on the pin 8, which passes through the turned-over extension 3C, Whose extreme end is bent at right` angles and secured by the pin 9, on which the pulley 6 is jonrnaled. This feature of bending around this extension will form the housing v3d to prevent the cord slipping oft the pulley 5, which feature is of more importance on this pulley than on the others by reason of lthe'fact that the controlling or operating portion of the cord passes over or leads from, this pulley.

The other pulleys 6 and 7 are journaled between the ears 3e and 4 and the latter pulley on the pin 10.

The roller 11 is an -ordinary spring-roller, and 12 is a bearing, Figs. 7 and 8, having the elongated slot 13, adapted to embrace the spring-winding projection 14. of the roller and is secured thereto bythe pointed screws 15. This slot is placed out of center between the two extreme endsof the bearing for the purpose Vof enabling the upper 4end to project above the roller to act as a buffer by such upperend striking against the bracket 3, and thus protect the curtain. In the drawings an ordinary-sized roller is used; but for alarger roller the bearing would be reversed. 16 and 17 are holes in the ends of said bearing fory the cord, presently to be described, to pass through. On the opposite or left-hand end of the roller, Figs. 9 and '10, is the other bearing 18, journaled on the body of the screwl 19, which screw is inserted in the end of the roller. 20 is a hole in the upper end of said bearing, through which the cord passes, while the end of such cord is anchored in the bifurcatedlower end 2l.

22 is a bracket secured to the casing by the screws 23 and 24, Fig. l. This latter screw, Fig. 6, also secures the cord-fastening cleat 25 to the outer face of this bracket. 26 represents lugs on the back of said cleat, which enter the elongated opening 27,.Fig. 5, of the bracket to prevent said cleat turning when secured thereto. The upper end of said bracket carries the cord-pulley 28, journaled on the pin 29. One cord only is' used in operating the device; but the portions or sections that run to the different parts will be designated by different figures of reference. The cord 30 is the one that operates the device and Whose lower end is free to be wound around the cleat 25 when the roller is adjusted to position. This cord passes around the pulley 5 of the bracket 3. Thence as section 50a it passes through the hole 16 in the upper end of the bearing 12 and thence outside of said bracket and through the hole 17 at the lower end of said bracket. Threading the cord through the upper andlower ends of the bracket gives that end of the roller a frictional support on thecord for the purpose to be hereinafter more fullydescribed. From the lower end of saidv bracket the cord passes around the pulley 28A of the lower bracket 22. From thence as section 30b it runs over the pulley 6, journaled on the pin 9 of the. upper left-hand bracket 3. From thence as section 30c it extends across the upper part of the window and over the .pulley 7, mounted on pin 10 of the upper left-hand bracket 4. From thence as section 80l it is passed through the hole 2O in the upper end of the right-hand bearing 18 and knotted, and from thence it passes over the outside of said bearing and is anchored in the bifurcated end 21. The object of passing the cord over and outside of the floating bearings is that the cord acts as a buer to' prevent direct contact of these metal bearings with the inside face of the window-casings in cases Where the wind blows the curtain or it is otherwise swung violently to one side. Without this provision the casing would be apt to be more or less defaced. Therefore the cord itself furnishes the cheapest and most efficient means for this purpose.

The arrangement shown ,whereby the rollerbearingl2 is mounted on the cord 30a, effectually prevents said bearing turning and consequently the accidental unwinding of the curtain-roller spring. This form of bearing and the manner of threading the cord through the top and bottom thereof imparts such a frictional contact between said cord and bearing that it cannot slip accidentally, but it can be shifted when necessary to adjust the horizontal position of the curtain-roller. While this can be done by hand, it is preferable to do so by manipulating the cord-section 30 in the manner presently to be described. The cord- sections 30 and 30d being the longest are liable to stretch, which will cause the right-hand end of the curtain-roller to drop lower than the opposite end,and while the cord can be taken up by withdrawing the end of section 30d from the lower bifurcated end of the bearing 18 and unloosening the knot at the upper end of said bearing such an arrangement is both tedious and unsatisfactory. The better way is to remove the cord 30 from the cleat 25 and raise the curtain-roller smartly to the top of the window, and as the upper end of the bearing 12 projects above said roller such end will strike against the bracket 3, and this sudden impact, combined with the weight of the roller, will jar the bearing down the said cord a distance suiiicient to level the said roller and cause the curtain 3l to hang straight. This position is automatically reached by the fact that as both of the roller-bearings project the same distance above the roller and the brackets 3 and 4 are on a line with each other it is quite evident that when the ri ght-hand rollerbearing also strikes against the bracket 4 the roller must be level. This self-adjusting featureA is a very important one in curtainfixtures of this character, where the roller is lowered from the top, as such roller is liable at any time to get out of level; but with my improved method of hanging the roller it can be leveled instantly.

While I show the bearing 12 frictionally connected to the cord-section 30a', it will be understood that the cord may be fastened to such bearing in a similar manner as shown at the upper end of the bearing 18; but such a construction is not as satisfactory, as the roller is not then self-adjusting.

Having thus described my invention,- What I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described improvement in spring curtain-roller fixtures, consisting of single and double cord-pulley brackets, the double one having .the housing 3d as shown, a cord running through said brackets, the curtain-roller having end bearings 12 and 18, said cord frictionally. connected to bearing 124and firmly anchored to the bearing 18, said bearing l2 having an elongated sloteccentrically located with respect to the ends of said bearing in which slot one end of the roller is supportedA for the purpose of reversing said bearing for different diameters of rollers, for the purpose set forth.

2. The combination, herein shown and described, consisting of the` double pulleybracket 3 and the single pulley-bracket 4, pulley-bracket 22 attached to the casing as shown, a single cord passing over said pulleys as follows: section 30 passing overpulley 5 of the bracket 3, from thence, as section 30, passing over pulley 28 of the bracket 22,

thence as section 30", passing over pulley 6 .0f said bracket 3, thence, as section 30e, pass` ing over pulley 7 of the bracket 4, with a curtain-roller carrying awinding-spring in. one end thereof, a bea-ring secured tothe spring-winding projection, the opposite ends of said bearing having openings therein Ido iid

through which the cord-section 30L passes and the said bearing is thus frictionally supported to such cord-section, said cord also operating as a buer to protect the windowcasing, a second bearing in which the opposite end of the roller is journaled, means for securing the cordsection 30d thereto, the ends of said bearings projecting above said roller so that, when such projecting ends are brought firmly against the brackets 3 and 4 the said roller is leveled, means for securing the free end of cord 30, for the purpose set forth.

8. In a curtain-fixture of the character described, the bracket 22 adapted to be secured to the lower part of the Window-casing and FRED H. BASSETT Witnesses:
