1 Claim. (Cl. 156-21) This invention relates to curtain operating ing a connection with suitable fasteners 29 which means and more particularly to means for the are secured to the curtain, and since each fastener support and operation of stage curtains. The 29 and swivel will be disposed in a vertical plane, objects of the invention, broadly, are to provide any swinging movement of the curtain due to 5 improvements in the track, the use of axleany cause, will be resisted. 1S
mounted double rollers and traction therefor, 'I'he fasteners 29 for the curtain are disposed noiseless movements of the hangers when the at uniform distances apart, and the cord or pullcurtains yare moved, and maintenance of the rope 26 slidably engages in the tubular sections. hangers in vertical planes midway between the The single primary hanger is indicated at B l0` double rollers. The invention also includes a (Figs. 2 and 3) and consists, in part, of four 10 primary roller of such construction that lateral or wheels 20 arranged in pairs, the wheels of each longitudinal movements may be avoided, and inpair being the same in all respects as the Wheels cludes stabilized mountings for the pulleys. o-r rollers 20 of the secondary hangers.

The ball or roller bearing best shown in Fig. 4 consists of an outer bearing-ring 50, an inner bearing-ring 5I and balls or rollers 52 between said'rings, these parts being conned as a complete unit, indicated at C by an annular cap 53 which covers the periphery and one end of the bearing-rings 50 and 5| and also covers the annular slot 54 at one side of said unit,` that part of the slot 54 at the opposite side of theunit being uncovered; and at 55 is indicatedjthe opening in the inner bearing-ring for receiving the end of an axle.
Numeral 56 indicates a bracket intermediate"j the ends of the track I5 upon the ,topi and.*c:ei1 trally thereof, and secured theretofby.keepers` 51,
and any suitable number of such 'brackets may be used, depending upon the; length fof "the track,
and since these brackets are disposed midway between the sides of the track the movable parts will normally be disposed in operative position to resist swinging movements.
I claim as my invention:
In operating means for a. curtain provided in spaced relation with upwardly projecting fastening devices, the combination with a track, the roller-bearing hangers supported by the track and having arms attached to said fastening devices, and `Ithe pull-rope for moving 'the hangers to dispose the curtain in extendedl position, of a ofpsaid fastening-devices to cause the formation *er folds-menthe curtain is extended.
