ABSTRACT:
Rectangular transparency panels form the sides of triangular units that are lighted from within. A gear train drives the units in synchronism. A base housing has a plurality of parallel aligned round posts projecting upwardly from it. The posts have a bore in which the lower end of a tubular lamp resides. Annular recesses around the posts have ring bushings in them. Gears having axially upwardly and downwardly projecting hub portions rotate concentrically to but not directly on the posts. The downwardly projecting hub portion has an annular shoulder that imparts a thrust load to the bushing and the hub extends through the bushing to be journaled for rotation. A gear cover arranged above the posts contains similar bushings that journal the upper hub portions and accept upward thrust load. The upper hub portions of the gears have axial slots. The end caps on which the lower end of the triangular units are slip fitted have hooked deflectable prongs extending from them for sliding into the slots and snapping onto the hub so the gears drive the end caps rotationally. A guide plate having bored pedestals for the upper ends of the tubular lamps to extend through and releasably mounted at a level above the base housing. Upper end caps for the triangular transparency units are journaled for rotation on the pedestals.
