ABSTRACT:
An adjusting mechanism for desired angle of an oscillating electric fan is disclosed. The adjusting knob is conveniently located about the top rear portion of the fan motor, adjacent the clutch knob. Adjusting the oscillating angle may be made when the fan is at rest, when it is running and oscillating at the same time, or when it is running at a fixed direction. Adjusting is fast and simple, only one hand is needed and no tools and mechanical know-how is necessary.
