ABSTRACT:
A flag waving machine for automatically waving a flag in a figure 8 pattern. A rod provides a support for the flag to be waved, this rod being attached to a pitman arm through a universal joint, the rod being pivotally supported in a bushing. The pitman arm is rotatably driven at one end to provide reciprocal motion of the rod, this reciprocal motion being guided in a figure 8 pattern by means of a guide channel. The channel is formed between a figure 8 shaped wall formed on a base member and a pair of spring-urged elliptical guide members which are also shaped and positioned to form a figure 8, the guide members operating to guide the path of the arm in the channel through a figure 8 pattern.
