Apparatus for storing a plurality of signs and automatically displaying said signs at predetermined timed intervals

An improved apparatus for storing a plurality of signs and automatically displaying them at timed intervals of the type having a pair of discs, each said disc affixed to the opposite ends of an elongated shaft and a plurality of panels, each said panel having copy placed on each side, pivotally mounted off center at each end around the periphery of said discs so that they can be displayed when they reach a strong display area in a rectangular box-like housing wherein the improvement comprises:

• (a) a plurality of elongated pins, each pin placed on each side of each panel;
• and
• (b) a pair of damping devices each of said damping device mounted within said housing adjacent one said disc, said damping device having a mounting plate affixed to a side portion of said housing, three different spring loaded adjustable cams pivotally affixed to said mounting plate to make operation of said apparatus smoother in appearance as said discs rotate, said three different spring loaded adjustable cams having a first cam member that is adjustably spring loaded by a spring tension adjustment member, a second cam member that is adjustably spring loaded by a spring tension adjustment member designed to make contact with the edge of said disc and to wedge said elongated pin between said second cam member and said first cam member as said discs rotate, and a third cam member designed to make contact with said second elongated pin on said second panel that has gone past said first and second cam members so that said second panel will be prevented from swinging back and forth and from hitting the other panels, and a modesty panel transversely affixed to said mounting plate to cover said cams when said damping device is mounted within said housing of said apparatus.
