Abstract: A generally planar base panel member has mounted to its back face a pair of laterally spaced apart chambers whose open fronts are covered by the panel. A pair of electrical receptacles in each chamber are arranged in alignment with apertures in the base panel. First and second front panels each have a neon tubing configuration mounted on a front side of the panel with the electric end terminals at opposite ends of the tubing configurations projecting through holes in the front panels so that when the front panels are juxtaposed to the front of the base panel the neon tube terminals plug into the receptacles. A power supply for neon tubing is mounted to the back face of the base panel member. The neon tubing configurations on the individual front panels when plugged into the receptacles form a series circuit which connects across the high voltage output terminals of the power supply.

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.

Abstract: A sign in which multiple scenes are presented in sequence is comprised of a plurality of juxtaposed rotationally driven display units that are assembled with triangularly-shaped hollow sleeves whose side panels are constituted by transparencies on each of which there is a portion of a different complete scene. There are adapters on the upper and lower ends of the display units which have bushings for allowing the juxtaposed display units to be journaled for rotation on a stationary light transmissive tubes that serves as axles. The tubes are retained at their lower ends in a row of equally spaced apart and colinear bores and they are retained at their upper ends by a plate which also has a corresponding row of bores that provide for stabilizing the upper ends of the tubes and for maintaining them in perfect alignment and spacing.
