ABSTRACT:
A simplified gear box for intermittently displaying a number of displays on a display apparatus is comprised of a partial gear driven by a drive shaft, the partial gear cooperates with a number of pins on a rotatable pin wheel which is secured to a triangular shaped display element so as to intermittently rotate the display element upon rotation of the pin wheel. A number of gear boxes are connected to a number of triangular elements to intermittently synchronously rotate all of the triangular display elements, to display different images upon a face of the display apparatus.
