ABSTRACT:
A rotating sign assembly has a plurality of rotatable, multi-sided, sign segments and a drive mechanism for rotatably driving the sign segments. The drive mechanism includes a drive shaft and one or more output shafts that each operate to rotate a multi-sided sign segment. A cam is fitted to each of the output shafts so that rotation of the cam causes rotation of the corresponding output shaft and sign segment. The cam has an outer perimeter and multiple equally spaced engagement slots which extend radially inwardly from the outer perimeter. Outwardly facing stabilizing portions are positioned between each of the engagement slots. The cam has multiple dwell positions, each corresponding to the display of one side of the multi-sided sign segment operated by the corresponding output shaft. A cam driver assembly is fitted to the drive shaft so that it rotates with the drive shaft. The cam driver assembly has a cam driver which extends outwardly from the axis of rotation and terminates in a knob. The knob describes an arc as the cam driver is rotated about the axis of rotation. The cam driver is configured to engage one of the engagement slots when the cam is in a dwell position and to rotate the cam to another dwell position as the cam driver assembly is rotated about its axis of rotation. The cam driver assembly also includes a stabilizing member which is configured to engage one of the stabilizing portions of the cam when the cam is in a dwell position.
