Abstract
A rotating sign assembly includes a number of multi-sided, rotatable sign segments driven by an elongated drive shaft operably interconnected with each of the sign segments. The drive shaft includes at least one multi-armed driven cam fitted to the drive shaft. Each arm of the driven cam includes an outer sloped driving surface and a peaked extremity. The driven cam is rotatably driven by a driving arm assembly comprising a driving pin plate and a driven arm stop plate. The driving pin plate includes a pair of pins, one situated on each end of the plate. Each driving pin alternatingly interacts with the outer sloped surfaces of the cam for rotation thereof, this rotation being halted by interaction of the peaked extremities alternatingly with the ends of the stop plate.
