ABSTRACT:
A portable fan providing oscillation in two axes. Oscillation may occur simultaneously in two axes, or in one selected axis. Two oscillation mechanisms are provided, each having its own oscillation motor and each being selectively operable independent of the other. Optionally, the main fan motor may be employed to power one oscillation mechanism. The fan has a base for desk top support, or a base and extensible column for floor support, or a bracket for permanent mounting. All embodiments have controls for controlling the fan motor and the oscillation motor or motors, and a limited tilting feature for maintaining the fan blade at an angle to the base or bracket.
