Abstract
A sign has slat panels mounted for sliding laterally on one side of a base plate and bars having cam followers mounted on the other side. Each bar has a pin, some of which project through slats in the bars and all of which project through slots in the base plate to terminate in a hole in the panels, respectively for driving the panels laterally in response to sequential lateral shifting of the bars. A first driven gear has axially extending cam pins of increasingly greater lengths to engage successive followers and shift the bars and panels to present a series of pictures. A second commonly driven gear has one cam pin which orbits in the opposite direction for periodically engaging all followers simultaneously and driving said bars back to initial position to start a new display cycle.
