ABSTRACT:
Theatrical equipment including riggings sets, light fixtures and the like are supported from a batten which is elevated and lowered relative to a stage floor by a plurality of ropes. The ropes are coupled to the batten and depend from a rectilinear array of rotary bodies mounted aloft. A mechanical coupling device intercouples the rotary bodies for providing simultaneous rotation of the bodies. An electrically energized drive device is also mounted aloft and is coupled to the array for causing rotation of the bodies. A locking device is mounted aloft and engages the coupling device for selectively enabling and inhibiting rotation. The ropes are coupled to the rotary bodies for causing ropes of different bodies to travel in laterally opposite directions for offsetting potential lateral movement of the batten. A plurality of rectilinear arrays of rotary bodies is provided which extends between a proscenium wall and a rear stage wall.
