ABSTRACT:
A sign having several movable panels with the panels each consisting of parallel strips interleaved with the strips of the other panels. The strips of one panel present a composite display when in view. A panel drive mechanism includes an endless motor driven member from which an arm projects and successively engages panel carried abutments located at points along the path of arm travel for panel positioning. Step-like guideways for the arm include inclined segments which divert the arm to cause the arm to disengage a panel abutment to terminate panel movement. Each sign panel is formed with overlapped strips which upon incorporation into a sign forms rows of interleaved panel strips. The composite display of each panel is presented in succession upon retraction of an overlying panel's strips back into a stored row of strips and again upon drawing of the panel strips to be viewed outwardly from their row positions.
